Description

A conveying and screening device and sorting equipment

Technical field

The invention belongs to the field of fruit sorting technology and equipment, and in particular relates to a conveying and screening device and sorting equipment.

Background technique

The fruit leaf and small fruit screening machine is in the process of screening fruits. Usually, the raw fruit will be mixed with some leaves, branches and small worthless fruits and other debris. When these debris flow into the rear section of the sorting line, they will block the sorting gap and even seriously affect the sorting efficiency. In order to solve this problem, perforated endless belt screening machines and fixed circulating drum screening machines are currently used.

Perforated Ring Belt Screening Machine: The debris in the raw fruit leaks into the lower layer through the holes in the upper layer of the ring belt. Because the leak holes of the upper belt and the lower belt cannot be aligned, the debris cannot be discharged, and most of the debris is drawn into the rear end drum of the ring belt. On the other hand, the screening effect is poor, the efficiency is low and the failure rate of the machine is greatly increased;

Fixed circulating drum screening machine: When the raw fruit flows into the fixed circulating drum screening machine, multi-layer accumulation is easy to occur. The debris contained in the accumulation layer cannot be spread out because the drum itself is fixed, so the debris cannot pass through the drum gap. Screening and discharge greatly reduces the effect and efficiency of the gap screening and the useless small fruits can only be screened with a fixed fruit diameter, thus reducing the flexibility and versatility of the equipment.

Please refer to Figures 1 to 3. Embodiments of the present application provide a conveying and screening device. The conveying and screening device is used to screen impurities in raw fruits, so that the impurities are filtered after passing through the conveying and screening device. The desired fruit Transported to the designated location by the transport device.

Referring to FIGS. 1 to 4 , the conveying and screening device includes a power structure 200 and a gap adjustment structure 300 . The power structure 200 includes a traversing rod located on the conveying surface 101 and a transmission member 201 for driving the traversing rod to move in the conveying surface 101. It can be understood that the conveying surface 101 is arranged horizontally, and the transmission The member 201 drives the traversing rod to move laterally along the conveying surface 101, and the traversing rod can slide a certain distance in the direction away from the conveying surface under the action of external force, that is, the traversing rod can jump up and down. Two of the transmission members 201 are arranged at intervals, and the two ends of the traversing rod are respectively connected to the two transmission members 201, and a plurality of the transverse rods are arranged at intervals along the transmission direction of the transmission member 201; it can be It is understood that the raw fruit is placed on a plurality of traversing rods on the conveying surface 101, and each traversing rod moves along the conveying surface 101. The raw fruit will move with the traversing rods, and the debris in the raw fruit will be removed. Will fall from the gap between two adjacent traversing rods, while the fruit in the raw fruit will remain on the traversing rod. The gap adjustment structure is used to guide the traverse rod moved to its position to jump in a direction away from the conveying surface to adjust the gap between the two adjacent traverse rods located at the gap adjustment structure. spacing.

When the traverse rod moves to the gap adjustment structure, the gap adjustment structure will drive the traverse rod to jump upward relative to the conveying surface 101, thereby increasing the size of the traverse rod located on the gap adjustment structure and its front and rear adjacent ones. Through the gap between the two traversing rods, larger debris of raw fruit and small worthless fruits within the set range are discharged from the traversing rod through the increased gap, thereby improving the screening efficiency, and the two The gap between the traversing rods is variable, which improves the versatility of the conveying and screening device and allows it to be adapted to different screening situations.

It can be understood that the gap adjustment structure can drive the traverse rod to jump in the direction away from the conveying surface by pushing upward. For example, the gap adjustment structure is a cylinder, and the piston rod of the cylinder pushes the traverse rod upward, so that The entire traverse rod moves upward, thereby increasing the distance between two adjacent transverse rods.

It can be understood that the gap adjustment structure includes a hook. When the traverse rod is located at the gap adjustment structure, the hook hooks the traverse rod and pulls the traverse rod upward so that the traverse rod moves in a direction away from the conveying surface. A jump is generated, which can increase the distance between two adjacent traverse rods.

In some embodiments, there are two gap adjustment structures 300, and the two gap adjustment structures 300 are respectively adjacent to the two transmission members 201.

At this time, the gap between the traverse rod and its front and rear traverse rods is the largest. The moving rod returns to the conveying surface 101 along the guide surface 3041. The next traversing rod continues to rise along the guide wheel 304, and each traversing rod passes the guide wheel 304 in sequence.

It can be understood that the traversing rod may not rotate, but only move linearly with the transmission member 201, that is, the raw materials are placed on a plurality of transverse rods arranged at intervals, and each transverse rod moves along with the transmission member 201. Moving forward, when passing through the gap adjustment structure 300, each traverse rod member jumps in sequence, thereby screening out large-diameter debris in the raw fruit. It can also be understood that the traverse rod also rotates during the movement of the transmission member 201, that is, the traverse rod not only moves in translation with the movement of the transmission member 201, but also the transverse rod During the forward translation process, a rotational movement around its own central axis 206 also occurs, that is, the traversing rod performs a planar motion, which can accelerate the removal of debris in the raw fruit through the rotation of the traversing rod itself. filter. In this embodiment, the transverse rod undergoes both translation and rotation. In other embodiments, the selection can be made according to the actual situation and is not limited here.

The limiting plate 205 moves along the predetermined direction along with the transmission member 201, so that The roller 202 is driven to move forward. It can be understood that the predetermined direction is perpendicular to the axial direction of the roller 202 and parallel to the conveying surface 101 . When the roller 202 passes the guide wheel 304, the guide wheel 304 will first lift the central shaft 206 upward, and the central shaft 206 will jump upward along the limiting groove 2051. At the same time, the central shaft 206 drives the roller 202 to jump upward, and the guide wheel 304 will then jump upward. The central shaft 206 is guided downward to lower the roller 202 to the conveying surface 101 .
