In addition, the bracket and the first horizontal conveyor belt The manner and position of the conveyor belt connection are easily determined by those skilled in the art, and the present invention is not limited here. For example, the bracket can be connected to the fixed point of the first horizontal conveyor belt by welding or riveting.

In the present invention, the motors used to control the movement of the first horizontal conveyor belt 11 and the second horizontal conveyor belt 21 are brake motors, and the brake motors are also called electromagnetic power-off brake motors and brake asynchronous motors. The prior art in the field is characterized in that the motor stops running immediately after power failure, and the brake can be realized within a few tenths of a second to achieve the effect of stopping at a fixed point. The specific method of using brake motors to control the movement of the first horizontal conveyor belt 11 and the second horizontal conveyor belt 21 can be realized by using related technical solutions in the prior art, which is not limited in the present invention.

In the present invention, the lift used can be a hydraulic lift commonly used in the field, preferably a four-column lift. Since the lift itself is also a prior art in the field, the present invention does not need to describe the structure of the lift in detail here. For example, the four-column lift disclosed in patent application CN105293369A can be used to realize the technical solution of the present invention, or some adjustments can be made to the four-column lift disclosed in CN105293369A to meet the needs of the present invention, of course The adjustments made do not require creative work for those of ordinary skill in the art.

The second horizontal conveyor belt 21 is fixed on the elevator 22 (more specifically, fixed on the lifting part of the elevator 22), and can also move vertically with the elevator 22, which can also be realized by using the prior art.

The present invention is electrically connected with the first brake motor and the second brake motor through a control circuit to further control the movement or stop of the incoming and outgoing double conveyor 10 and the elevator airborne double conveyor 20, that is, the first level The motion or stop of conveyer belt 11 and second horizontal conveyer belt 21; The inventor believes that for those of ordinary skill in the art, according to the description of the function of the control circuit in this present invention, the structure of the control circuit itself and the structure of the control circuit itself can be realized without creative work. The electrical connection between the control circuit and the brake motor. In practical applications, in order to facilitate the operator to control the movement or stop of the incoming and outgoing double-link conveyor 10 and the elevator-mounted double-link conveyor 20 through the control circuit, several buttons can also be connected to the control circuit; Set a forward start button, a reverse start button and a stop button, the forward start button is used to control the movement of the first horizontal conveyor belt 11 and the second horizontal conveyor belt 21 to the direction of the wind tunnel, and the reverse start button is used to control the first level The conveyor belt 11 and the second horizontal conveyor belt 21 move away from the wind tunnel; further, the control circuit can also be connected with the motor of the elevator 22 to control the rise and fall of the elevator 22, and then control the onboard double conveyor 20 of the elevator. rise or fall.

In the technical solution of the present invention, the position of the loading and unloading double conveyor 10 is fixed, while the position of the elevator-mounted double conveyor 20 is fixed in the horizontal direction, but movable in the vertical direction. For the positional relationship between the two, it should be understood that when the second horizontal conveyor belt 21 moves vertically to be on the same level as the first horizontal conveyor belt 11, the second horizontal conveyor belt 21 and the first horizontal conveyor belt 11 are aligned with each other along their moving direction. near. The degree of proximity should only prevent that when the wind tunnel sample 01 is transferred from the incoming and outgoing double conveyor 10 to the elevator onboard double conveyor 20, the wind tunnel sample 01 will not fall or other abnormalities will occur. It is enough to transfer from the incoming and outgoing double conveyor 10 to the situation on the elevator airborne double conveyor 20. For example, when the second horizontal conveyor belt 21 moves vertically to be on the same level as the first horizontal conveyor belt 11, the second horizontal conveyor belt 21 moves vertically. The distance between the horizontal conveyor belt 21 and the first horizontal conveyor belt 11 along their moving direction may be less than 20 cm.

The horizontal transmission of the conveyor belt 21, the transmission direction is to the bottom of the wind tunnel 02. The wind tunnel sample 01 is first transported on the first horizontal conveyor belt 11, and then moved to the second horizontal conveyor belt 21 for transportation. When the wind tunnel sample 01 reaches below the sample inlet of the wind tunnel 02, the operator triggers the connection with the control circuit stop button, the second horizontal conveyor belt 21 stops the horizontal transmission, and due to the effect of stopping at a fixed point of the brake motor, the wind tunnel sample 01 can be parked directly below the sample entrance; then the weighing button is triggered to control the elevator 22 Moving downwards, when the horizontal position of the second horizontal conveyer belt 21 is lower than the horizontal position of the weighing device 30, it stops, and now the wind tunnel sample 01 is positioned on the weighing device 30 (the weighing device 30 is positioned at the sample entrance directly below), after weighing the weight of the wind tunnel sample 01, trigger the test button to control the upward movement of the elevator 22, and the wind tunnel sample 01 can be directly transported from the sample inlet into the wind tunnel for the wind tunnel test. , trigger the weighing button, control the elevator 22 to move downward, weigh the weight of the wind tunnel sample 01 after the test, and then trigger the return button, so that the second horizontal conveyor belt 21 and the first horizontal conveyor belt 11 are located on the same plane, and then The reverse start button is triggered again, and the wind tunnel sample 01 is transported out in the reverse direction through the first horizontal conveyor belt 11 and the second horizontal conveyor belt 21 .
