Turn the handle; the brush includes a brush handle, the top of the brush handle is evenly distributed with bristles, and the brushes are arranged on the lower horizontal rod in a straight line and evenly spaced.

According to the above scheme, the transmission rod is a hollow rod with an open end, and the open end passes through the box body and is connected to one end of a hose, and the other end of the hose is connected to a high-pressure medium source.

According to the above solution, the brush handle is a hollow structure, and several through holes are evenly opened on the top of the brush handle.

According to the above solution, a cut-off valve is provided on the open end of the transmission rod.

According to the above scheme, the bearing holes on the two side walls of the box are provided with fasteners, and the fasteners are two blocks arranged on the inner and outer end faces of the side walls of the box. There is a circular hole in the center, the inner wall of the circular hole is in contact with the outer peripheral surface of the bearing, and the block on the outer end surface is connected with the bearing end cover through bolts.

According to the above solution, the lower horizontal bar is provided with a protrusion, and the protrusion is in contact with the inner end surface of the block on the inner end surface.

The beneficial effects of the present invention are: 1. The surface of the spiral blade is scraped by a wear-resistant soft brush, and then sprayed and rinsed with water or compressed air, so that the cleaning efficiency is high; 2. The cleaning mechanism can be realized by manually rotating the transmission rod The switch between working state and standby state is easy to operate; 3. The cleaning force of the blade is mainly from the rotation of the blade shaft, which saves labor; 4. Manually swinging the transmission shaft at a small angle can realize cleaning of two blade shafts at the same time, with high efficiency.

detailed description

In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

As shown in Figure 1-4, a blade cleaning device for a screw conveyor mechanism includes a transmission rod 1 and a brush. The transmission rod 1 is a bent rod with two right angles, and its lower horizontal rod passes through the bottom of the screw conveyor mechanism. The bearing holes on the two side walls of the casing 5 are placed above the screw blade shaft 4, the lower horizontal bar is connected to the casing 5 through the bearing 6, and the upper horizontal bar of the transmission rod is a rotating handle, which can be manually rotated; the brush includes The brush handle 2, the top of the brush handle 2 is evenly distributed with bristles, and the brushes are arranged in a straight line and evenly spaced on the lower horizontal rod of the transmission rod. The contact or separation between the brush and the spiral blade shaft 4 is controlled by manual rotation, so as to realize the standby state and the working state. State switching.

The transmission rod is a hollow rod with an open end, and its open end passes through the box body 5 and is connected to one end of the hose 7, and the other end of the hose 7 is connected to a high-pressure medium source. It is also a hollow structure. Several through holes 13 are evenly opened on the top of the brush handle (see Figure 5). The cut-off valve 8 controls the on-off of the high-pressure medium. The high-pressure medium can be gas or liquid. The spiral blade shaft 4 is cleaned by the brush During this time, high-pressure gas or liquid can be ejected from the through hole 13 to blow the screw blade shaft.

The bearing holes of the two side walls of the box body 5 are provided with fasteners. The fasteners are two blocks 9 located on the inner and outer end faces of the side walls of the box body. The center of the block body 9 has a round hole, and its inner wall In contact with the outer circumferential surface of the bearing 6, the outer block and the bearing end cover 10 are connected by bolts 11, and the wall thickness of the box is increased through the inner and outer blocks to make the connection between the transmission rod and the two side walls of the box more stable. Protrusions 12 are provided on the horizontal bar, and the protrusions 12 are in contact with the inner end surface of the inner block to position the fastener.

In the working state, the screw blade shaft 4 rotates, the brush scrapes the surface of the screw blade shaft, and at the same time opens the stop valve 8, supplemented by high-pressure medium flushing, which not only cleans the screw blade shaft, but also rinses the brush; Swing the hairbrush back and forth in the angle range, and one brush head can clean the two blades 14 of the helical blade shaft at the same time; Can enter standby mode.
