Description

Technical Field

[0001] The invention relates to the technical field of scraper conveyors, in particular to an agricultural grain scraper conveyor. Background Art

[0002] Scraper conveyors are mostly horizontal conveyors with a simple structure. They can transport materials from the feed end to the discharge end. They consist of a cabin and sprockets arranged at the feed and discharge ends of the cabin, and a scraper plate transmitted between the two sprockets through a chain. The material is put into the cabin from the feed port and falls on the scraper plate, and then the scraper plate is transferred to the discharge end to complete the discharge. It is mostly used in grain transportation.

[0003] Through searching, the Chinese patent with the announcement number CN119329990B discloses a chain scraper conveyor, which includes a frame, a chain, a scraper mechanism, a conveyor belt and a synchronization mechanism. By cooperating with the sliders and the chute at both ends of the scraper plate, the scraper plate is always perpendicular to the chain, which solves the problem of wear between the scraper plate and the outer shell caused by the deflection of the scraper plate due to the force of the chain in the scraper conveyor in the prior art; in addition, by changing the relative movement between the support platform and the scraper plate to a synchronous movement of the two, friction and wear between the scraper plate and the support platform are avoided. By setting up a synchronization mechanism, the conveyor can adjust the relative movement relationship between the scraper plate and the conveyor belt according to different working conditions. When the material is heavy, the scraper plate moves relative to the conveyor belt to push the material on the conveyor belt; when the material is light, the two move synchronously, reducing the wear between the conveyor belt and the scraper plate and the bending wear of the conveyor belt, further extending the service life.

[0004] The scraper conveyor in the prior art will wear out the scraper assembly during the conveying process, which will increase the fitting clearance and cause material leakage. Moreover, when the bottom plate turns a corner, the existing scraper cannot fit the bottom plate and stably push the material to move. At the corner position, the fitting clearance between the scraper and the bottom plate will change, which will cause material leakage. Therefore, an agricultural grain scraper conveyor is proposed to solve the above problems. Summary of the Invention

[0010] Preferably, the upper end of the receiving plate is a cavity, the inner wall of the cavity is slidingly connected to the upper end surface of the compensation spring plate, and the lower end of the outer surface of the cavity is provided with a chamfer to prevent the material from being stuck in the lower end surface of the cavity.

[0013] Preferably, the traction mechanism includes a reel and a reel rope. The reel is arranged on the inner side of the arc-shaped plate of the receiving plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1.

By arranging a receiving plate and a compensation spring plate to wrap around the outside of the scraper assembly, the material will not be directly stuck in the roller of the scraper assembly. By arranging a circular arc chamfer at the lower end of the material-discharging spring piece, the friction loss between the material-discharging spring piece and the guide base plate when moving is reduced, thereby reducing the friction loss of the scraper when moving, and solving the problem that the scraper will cause loss due to continuous friction when moving, resulting in an increase in the fitting gap and leakage during transportation. 2. The agricultural grain scraper conveyor sets a compensation spring plate that slides on the inner side of the receiving plate, and sets an extrusion shaft to rotate and push the compensation spring plate, so that the compensation spring plate can be extended in time at the corner position of the scraper assembly, so that the material-diverting spring piece can fit closely with the guide base plate. By setting a lifting assembly, the material-diverting spring piece can be bent and fit on the surface of the receiving plate after being extended, so that the material-diverting spring piece will not be subjected to excessive stress and deformation, achieving the effect of protruding the material-diverting spring piece and fitting it to the guide base plate at the corner position, solving the problem of increased fitting clearance at the corner position during material transportation, which is prone to material leakage. 3. The agricultural grain scraper conveyor drives the scraper assembly to move by dragging a chain, and sets a limit mechanism at both ends of the scraper assembly so that the limit mechanism slides on the inside of the side fence, making the movement of the scraper assembly more stable, achieving the effect of stable material conveying, and solving the problem of unstable scraper assembly and prone to material leakage during movement.

[0032] like Figure 1-11 As shown, the agricultural grain scraper conveyor includes a side plate 1 and a guide bottom plate 2. A supporting wheel is provided on the inner side of the side plate 1, and a drag chain 3 is sleeved on the outer surface of the supporting wheel. There are multiple groups of supporting wheels according to the direction and turning angle of the drag chain 3, which are used to support the outline of the drag chain 3 and drive the drag chain 3 to rotate.

[0033] A tensioning device 21 is provided on the outside of the support wheel for adjusting the tightness of the drag chain 3. A scraper assembly 4 is connected to the surface of the drag chain 3. The scraper assembly 4 is a flat frame. A force shaft is provided on the upper end of the scraper assembly 4 for being driven by the drag chain 3 to pull the scraper assembly 4. A roller is provided at the lower end of the scraper assembly 4 for moving on the surface of the guide base plate 2 to reduce friction. The scraper assembly 4 can be driven by the drag chain 3 to move and push the material to slide and transport on the surface of the guide base plate 2. By arranging a roller at the lower end of the scraper assembly 4, the scraper assembly 4 will not have direct friction with the guide base plate 2 during movement, thereby reducing wear on the guide base plate 2 and the scraper assembly 4.

[0034] Limiting mechanisms 5 are provided at both ends of the scraper assembly 4 to prevent the scraper assembly 4 from tilting during movement. Side blocks 6 are provided on the outside of the limiting mechanism 5. A support frame is provided in the middle of the limiting mechanism 5. The four sharp corners of the support frame are provided with cylindrical sliding keys, and the sliding keys are in sliding contact with the side blocks 6. The limiting mechanism 5 is provided with cylindrical sliding keys at the sharp corners of the support frame to minimize friction during the sliding process of the limiting mechanism 5. The cylindrical sliding keys are provided to make the limiting mechanism 5 smoother at the corner position. Through the setting of the limiting mechanism 5, the scraper assembly 4 can push the material for transportation neatly and smoothly under the drive of the drag chain 3.

[0035] The side enclosure 6 is arranged on the surface of the side plate 1, and the side enclosure 6 is arranged on the outside of the drag chain 3. A chute is arranged on the surface of the side enclosure 6, and the limiting mechanism 5 slides inside the chute of the side enclosure 6. The inner wall of the outer side of the chute of the side enclosure 6 is arranged to be inclined to guide the entering material to fall quickly. The side enclosure 6 is arranged on the side of the scraper assembly 4 so that the scraper assembly 4 will not leak material on the side when pushing the conveyed material. By arranging a chute on the surface of the side enclosure 6, the limiting mechanism 5 can move along the preset track. By arranging the outer wall of the chute of the side enclosure 6 to be inclined, the material that accidentally enters the chute can fall quickly or be pushed to fall.

[0036] A squeezing mechanism 7 is provided on the inner side of the scraper assembly 4, and a receiving plate 8 is provided on both sides of the scraper assembly 4. The squeezing mechanism 7 passes through the outer shell of the receiving plate 8 surface and is provided inside the cavity of the receiving plate 8. A compensation spring plate 9 is slidingly provided on the inner side of the receiving plate 8. The squeezing mechanism 7 includes a pushing tooth 71, and the pushing tooth 71 is provided on the inner side of the scraper assembly 4. The surface of the pushing tooth 71 is engaged with an squeezing shaft 72. The middle of the squeezing shaft 72 is a round shaft, and cams are provided at both ends of the round shaft. The cam is provided on the inner side of the receiving plate 8, and the surface of the round shaft is provided with matching teeth. The matching teeth are engaged with the pushing tooth 71. The squeezing mechanism 7 pushes the squeezing compensation spring plate 9 to slide on the inner side of the receiving plate 8 through the rotation of the cam. By providing the motor on the inner side of the scraper assembly 4 and driving the pushing tooth 71 by the motor, the pushing tooth 71 can control the angle of the squeezing shaft 72, thereby controlling the squeezing angle of the compensation spring plate 9.

[0037] The upper end of the receiving plate 8 is a cavity, and the inner wall of the cavity is slidingly connected to the upper end surface of the compensation spring plate 9. The lower end of the outer surface of the cavity is provided with a chamfer to prevent the material from being stuck in the lower end surface of the cavity. The lower end of the receiving plate 8 is an arc-shaped plate, and the arc-shaped plate does not contact the guide bottom plate 2. The receiving plate 8 is able to wrap the cam of the extrusion shaft 72 on the inside by providing a cavity at the upper end. By providing the arc-shaped plate, the compensation spring plate 9 can use the arc-shaped plate as a support after being extruded, thereby preventing the compensation spring plate 9 from being excessively deformed by extrusion.

[0038] The lower end of the receiving plate 8 is provided with a traction mechanism 10, and the compensation spring plate 9 includes a slide plate 91. The slide plate 91 is slidably connected to the inner wall of the cavity of the receiving plate 8. The end face of the slide plate 91 is "L"-shaped. The outer surface of the slide plate 91 contacts the cam of the extrusion shaft 72. The lower end of the slide plate 91 is provided with a material-dispensing spring piece 92. The lower end of the material-dispensing spring piece 92 is provided with an arc chamfer. The compensation spring plate 9 is provided with a sliding fit in the cavity of the receiving plate 8, so that the compensation spring plate 9 and the receiving plate 8 are more tightly connected. To prevent the material from entering the fitting gap, a compensation spring plate 9 and a receiving plate 8 are arranged on the outside of the scraper assembly 4, so that the material-discharging spring piece 92 can prevent the material from being stuck in the gap between the scraper assembly 4 and the guide base plate 2. By setting a circular chamfer at the lower end of the material-discharging spring piece 92, the friction of the material-discharging spring piece 92 when sliding on the surface of the guide base plate 2 is minimized, and the characteristic of the material-discharging spring piece 92 that it can bend and deform makes the material-discharging spring piece 92 and the guide base plate 2 fit more closely, thereby preventing leakage.

[0039] The traction mechanism 10 is connected to the compensation spring plate 9. The traction mechanism 10 includes a winding shaft 101 and a winding rope 102. The winding shaft 101 is arranged on the inner side of the arc plate of the receiving plate 8. The winding rope 102 is wound around the surface of the winding shaft 101. The free end of the winding rope 102 is fixedly connected to the material-diverting spring piece 92. The traction mechanism 10 can pull the material-diverting spring piece 92 through the winding traction of the winding rope 102. The material-diverting spring piece 92 is always in contact with the guide base plate 2 at the corner position.

[0040] A lifting assembly 11 is provided between the receiving plate 8 and the compensation spring plate 9, which is used to pull the compensation spring plate 9 up. The lifting assembly 11 includes a spring shaft 111. The upper end of the spring shaft 111 is provided in the cavity of the receiving plate 8. The outer surface of the lower end of the spring shaft 111 is slidingly connected to the slide plate 91. A lifting spring 112 is sleeved on the outer side of the spring shaft 111. One end of the lifting spring 112 is fixedly connected to the receiving plate 8, and the other end is fixedly connected to the slide plate 91. The lifting assembly 11 connects the receiving plate 8 and the compensation spring plate 9 together through the lifting spring 112, so that the compensation spring plate 9 can be maintained at a suitable height and can still be reset in time after being squeezed.

[0041] When in use, first set the device in a suitable position, and start the motor to drive the support wheel to rotate, so that the support wheel rotation drives the drag chain 3 to rotate, and the drag chain 3 drives the scraper assembly 4, so that the scraper assembly 4 moves along the slide groove on the surface of the side fence 6 under the restriction of the limiting mechanism 5, so that the scraper assembly 4 moves on the surface of the guide base plate 2 under the drag of the drag chain 3, and the material to be transported is placed on the surface of the guide base plate 2, and the scraper assembly 4 is driven by the drag chain 3 so that the material is pushed on the surface of the guide base plate 2. The roller at the lower end of the scraper assembly 4 rolls on the surface of the guide base plate 2 to reduce friction, and the receiving plate 8 and the compensation spring plate 9 are set on the outside of the scraper assembly 4 to prevent the material from passing through the gap of the scraper assembly 4. When the guide base plate 2 turns a corner, the pushing tooth 71 is driven to rotate by the starting motor, so that the pushing tooth 71 drives the extrusion shaft 72 to rotate. The cam on the surface of the extrusion shaft 72 rotates and presses down the compensation spring plate 9. The compensation spring plate 9 slides down on the receiving plate 8 under pressure, causing the material-dispensing spring piece 92 to drop and contact the surface of the guide base plate 2. At the same time, the motor is started to drive the reel-up shaft 101 to wind the reel-up rope 102, so that the material-dispensing spring piece 92 moves closer to the receiving plate 8, so that the material-dispensing spring piece 92 can fit the curved plate of the receiving plate 8 when it is extended and bent, so that the material-dispensing spring piece 92 will not be deformed after being subjected to force. By extending the material-dispensing spring piece 92 to fit the guide base plate 2, when the scraper assembly 4 pushes the material, there will be no situation where the scraper assembly 4 encounters a corner when pushing the material on the surface of the guide base plate 2 and leaks the material from the fitting gap. When the scraper assembly 4 passes the corner, the extrusion shaft 72 and the reel-up shaft 101 are reset, the compensation spring plate 9 is reset, and finally the scraper assembly 4 moves in a straight line on the surface of the guide base plate 2 to complete the material conveying.
