DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0035] In one embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a feeding device for a grain conveyor, comprising:

[0036] A conveyor body 2, wherein the conveyor body 2 has a material conveying cavity;

[0037] A feed hopper 1 is provided at a side of the feeding end adjacent to the conveyor body 2, a material passing cylinder 14 is provided between the feed hopper 1 and the conveyor body 2, the feed hopper 1 is connected to the feeding cavity of the conveyor body 2 through the material passing cylinder 14, and a stirring assembly 5 is provided in the feed hopper 1; for example, Figure 2 As shown, the stirring assembly 5 includes a second motor 51, a stirring rod 52, a cantilever 53 and a mounting frame 11, the cantilever 53 is fixedly arranged on the mounting frame 11, the second motor 51 is fixedly arranged on the cantilever 53, and the stirring rod 52 is drivingly connected to the output shaft of the second motor 51, which is used to stir the grain in the feed hopper 1 to avoid the formation of a "rat hole";

[0038] It should be noted that "rat hole" refers to the uneven flow of materials during the unloading process, resulting in the material flow in certain areas of the bottom of the silo 4 being replaced by local voids or channels, while the material in other areas may still be accumulated or stagnant. This phenomenon looks like a small hole.

[0039] Feed components, such as Figure 4 As shown, the material passing component is arranged on the material passing barrel 14, and the material passing component includes a material dispersing rod 137, a material dispersing driving component and a shifting and adjusting distance component. The material dispersing driving component is arranged on the outside of the material passing barrel 14, and the output end of the material dispersing driving component is transmission-connected with the material dispersing rod 137, and the output end of the material dispersing rod 137 passes through the material passing barrel 14 and is slidingly connected with the material passing barrel 14, and the shifting and adjusting distance component is transmission-connected with the material dispersing driving component. Under the periodic distance adjustment of the shifting and adjusting distance component, the material dispersing rod 137 is shifted multiple times within the cycle, and the shifting distance gradually increases.

[0040] In the above embodiment, if Figure 1As shown, the grains need to be uniformly transported to the silo 4 with the help of the conveyor body 2, by first putting the grains into the hopper 1, and then falling into the feeding cavity of the conveyor body 2 through the feeding barrel 14. In order to avoid the grains in the feeding barrel 14 from being blocked due to friction or obstruction between each other, the discharging rod 137 is shifted multiple times within a cycle, and the movement law of gradually increasing the shifting distance is used, that is, the distance value of the discharging rod 137 extending into the feeding barrel 14 gradually increases, so that the discharging rod 137 can gradually loosen the grain materials in the feeding barrel 14, and avoid further tightening of the grain materials due to excessive force applied at one time, that is, gradually increasing the distance that the discharging rod 137 extends into the feeding barrel 14, which helps to disperse the pressure and allow the material to flow gradually without generating a strong sense of pressure, which is conducive to removing the blockage.

[0041] For example, see Figure 4 The end of the material dispersing rod 137 located in the material passing cylinder 14 is a material extruding end 1371, the lower part of the material extruding end 1371 is a circular arc convex surface, and the upper part of the material extruding end 1371 is an inclined surface. The tip of the material extruding end 1371 is convenient for extruding into the grain, and the grain is squeezed toward the lower material passing direction by means of the circular arc convex surface, which is helpful for material dispersing.

[0042] For example, see Figure 4 and Figure 8 The material dispersing driving assembly includes a driving member, an eccentric column 135 and a connecting rod 136. The output end of the driving member is connected to the eccentric column 135 in a transmission manner. Under the transmission of the driving member, the eccentric column 135 performs eccentric motion. The eccentric column 135 is rotatably connected to the connecting rod 136. The end of the connecting rod 136 away from the eccentric column 135 is rotatably connected to the material dispersing rod 137. Through the eccentric motion of the eccentric column 135, the material dispersing rod 137 driven by the connecting rod 136 extends into the grain material in the material barrel 14 in a motion law of first accelerating and then decelerating. During the acceleration process, the material dispersing rod 137 can more easily break through the surface resistance of the grain material and quickly enter the blocking area. At this time, the loosening of the material will make the subsequent advancement smoother, so that the material dispersing rod 137 only needs to decelerate and move forward to achieve dynamic material dispersing of the material dispersing rod 137.

[0043] For example, see Figure 4 , Figure 7 and Figure 8The shifting and adjusting distance assembly includes a shifting member 139, an arc plate 138, a spring 1353, a guide slider 1351 and a guide rail 1352. The output end of the driving member is connected to the guide rail 1352 in a transmission manner. The guide slider 1351 is slidably connected in the guide rail 1352. One end of the guide slider 1351 located in the guide rail 1352 is fixedly connected to a guide rod 1354. The guide rod 1354 is sleeved with a spring 1353. The guide slider 1351 is located in the guide rail One end outside 1352 is fixedly connected to the eccentric column 135, and the output end of the displacement member 139 is fixedly connected to the arc plate 138, and the arc plate 138 has an arc concave surface on the side facing the eccentric column 135, and the displacement member 139 is used to adjust the limit position of the arc plate 138, wherein the arc radius of the arc plate 138 is larger than the eccentric motion trajectory radius of the eccentric column 135, wherein the arc plate 138 is located between the eccentric column 135 and the barrel 14.

[0044] It should be noted that the displacement member 139 is a hydraulic expansion member, an electric expansion member, etc., which is not limited here. Figure 8 Taking the position shown in the figure as an example, under the drive of the shifting member 139, the arc plate 138 moves rightward from the leftmost position to the rightmost initial position, and the arc plate 138 gradually moves rightward to the limit position of the eccentric column 135. It should be noted that the linear distance of the eccentric column 135 from the leftmost position to the rightmost position and the limit position of the arc plate 138 in friction contact with the arc plate 138 is the displacement distance of the material discharging rod 137 extending into the material barrel 14. Therefore, when the arc plate 138 gradually moves rightward to the limit position of the eccentric column 135, the displacement distance of the material discharging rod 137 gradually increases, so that the material discharging rod 137 can gradually loosen the grain material in the material barrel 14 to avoid further tightening of the grain material due to excessive force applied at one time. After completing a cycle of material discharging operation, the arc plate 138 continues to return to the leftmost position and repeats the above action. When the eccentric column 135 is subjected to the friction and compression of the arc plate 138 , the guide sliding block 1351 slides toward the guide rail 1352 , thereby compressing the spring 1353 .

[0045] For example, see Figure 4 and Figure 6The driving member includes a first motor 131, a first gear 132, a first gear ring 1331, a second gear ring 1332 and a second gear 134. The output end of the first motor 131 is fixedly connected to the first gear 132, and the first gear 132 is meshed with the first gear ring 1331. The outer side of the material barrel 14 is fixedly provided with a shell 12, and the inner side of the shell 12 is fixedly provided with a limit seat 1333, and the limit seat 1333 is slidably connected with the limit ring 133. The first gear ring 1331 is fixedly provided on the limit ring 133, and the limit ring 133 is also fixedly provided with a second gear ring 1332. The second gear ring 1332 is meshed with the second gear 134 for transmission, wherein the first gear ring 1331 and the second gear ring 1332 are respectively located on both sides of the limit ring 133, and the output shaft of the second gear 134 is fixedly connected with a guide rail 1352.

[0046] There are multiple material dispersing rods 137, and the multiple material dispersing rods 137 are evenly distributed on the material passing barrel 14 in the circumferential direction. The number of the second gears 134 is consistent with the number of the material dispersing rods 137, and the multiple second gears 134 are all meshed with the second gear ring 1332. Under the drive of the first motor 131, the material dispersing operation of the multiple material dispersing rods 137 is realized. It should be noted that Figure 6 It is shown in the figure that there are four second gears 134. In other embodiments, the number of the second gears 134 can be five, six, seven, etc., and the material discharging rods 137 are correspondingly arranged, which is not limited here.

[0047] It should be noted that, please continue to refer to Figure 4 The sliding direction of the material discharging rod 137 and the material passing barrel 14 is parallel to the radial direction of the material passing barrel 14. In other embodiments, continue to refer to Figure 5 The second gear ring 1332 is a bevel gear ring, and the second gear 134 is a bevel gear. Through the meshing transmission of the bevel gear ring and the bevel gear, the material dispersing rod 137 is set at an angle, that is, there is an angle between the sliding direction of the material dispersing rod 137 and the material barrel 14 and the radial direction of the material barrel 14, and the extruding end 1371 of the material dispersing rod 137 is set toward the discharge direction of the material barrel 14, so that under the reciprocating movement of the material dispersing rod 137, the inclined material dispersing rod 137 has a tendency to push the food material in the discharge direction, which is helpful for material dispersing.

[0048] For example, see Figure 3 and Fig.10A material guide cylinder 242 is also provided between the material through cylinder 14 and the conveyor body 2. The material through cylinder 14 is connected with the material feeding cavity between the conveyor body 2 through the material guide cylinder 242. A material guide assembly 24 is provided in the material guide cylinder 242. The material guide assembly 24 includes a material guide plate 245 and a buffer assembly. The material guide plate 245 is tiltedly arranged in the material guide cylinder 242. The upper end of the material guide plate 245 is rotatably connected to the material guide cylinder 242, and a torsion spring is provided on the rotating shaft of the material guide plate 245. A buffer assembly is provided on the lower side of the material guide plate 245. The output end of the buffer assembly abuts against the material guide plate 245. Under the drive of the buffer assembly, the opening size between the lower end of the material guide plate 245 and the material guide cylinder 242 is dynamically adjusted.

[0049] While the guide plate 245 is guiding the material, the guide plate 245 swings under the transmission of the buffer assembly, so that the actual discharge opening is dynamically retracted and released, effectively avoiding the material from being blocked at the discharge port of the guide barrel 242.

[0050] For example, see Fig.10 The buffer assembly includes an abutment driving member 246, an abutment member 2461, a swing arm 248 and a protrusion 249. The abutment driving member 246 is transmission-connected with the abutment member 2461, and the abutment member 2461 frictionally abuts against the swing arm 248. One end of the swing arm 248 is rotationally connected to the mounting seat of the abutment driving member 246, and the other end of the swing arm 248 is provided with a protrusion 249, which frictionally abuts against the lower side surface of the guide plate 245.

[0051] Under the drive of the abutment driving member 246, the abutment member 2461 abuts against the swing arm 248 reciprocatingly, causing the swing arm 248 to swing. Fig.10 Taking the shown position as an example, when the abutment 2461 moves outward and the swing arm 248 swings counterclockwise, the protrusion 249 pushes the material guide plate 245 to swing counterclockwise. When the abutment 2461 moves inward, under the pressure of the material accumulation and the reset action of the torsion spring, the material guide plate 245 swings clockwise and resets, so that the protrusion 249 drives the swing arm 248 to swing clockwise to the initial position synchronously, so that the abutment 2461 is always in frictional contact with the swing arm 248.

[0052] It should be noted that a fixed block 247 is fixedly connected to the side of the mounting seat of the abutting driving member 246, and a sliding groove 2471 is opened on the fixed block 247, so that the limiting column on the side of the swing arm 248 is slidably connected to the fixed block 247 through the sliding groove 2471 to constrain and support the swing of the swing arm 248.

[0053] For example, see Fig.10The side of the material guide barrel 242 is provided with an inspection port, and an inspection plate 244 is hingedly connected to the position of the material guide barrel 242 corresponding to the inspection port. The upper end of the material guide plate 245 is rotatably connected to the inspection plate 244, and the mounting seat of the abutting driving member 246 is fixedly arranged on the inspection plate 244. By opening the inspection plate 244, the material guide assembly 24 can be moved outward to the outside of the material guide barrel 242, so as to facilitate the inspection of the equipment.

[0054] It should be noted that if Fig.10 As shown, the upper part of the guide barrel 242 is fixedly connected to the housing 12 through the upper connecting plate 241, and the lower part of the guide barrel 242 is fixedly connected to the conveying box 22 through the lower connecting plate 243, and the opening size of the feeding end of the guide barrel 242 is larger than the opening size of the feeding end of the through barrel 14, which is helpful for conveying grain materials and avoiding grain blockage. Among them, the inspection plate 244 is hinged to the guide barrel 242 through the hinge joint 2442, and the inspection plate 244 is limited by the latch 2441 to control the opening or closing state of the inspection plate 244.

[0055] For example, see Figure 1 , Figure 2 and Fig. 9 The conveyor body 2 includes a third motor 21, a conveying box 22 and a spiral feed rod 23. The spiral feed rod 23 is arranged in the feed cavity of the conveying box 22. The input end of the spiral feed rod 23 is transmission-connected with the output end of the third motor 21. The discharge end of the conveying box 22 is provided with a discharge pipe 3, which is connected to the feed cavity of the conveying box 22, so that the grain materials are uniformly transported to the silo 4 for storage or transportation.

[0056] It should be noted that, when the feeding device of the grain conveyor is in use, grain is put into the feed hopper 1, and driven by the second motor 51, the stirring rod 52 stirs the grain in the feed hopper 1, so that the grain is continuously fed into the feeding barrel 14, thereby avoiding the formation of a "rat hole" due to excessive grain accumulation, which causes the problem of material blockage in the feed hopper 1;

[0057] Moreover, a material passing assembly is arranged in the material passing barrel 14, and the guide rail 1352 drives the guide sliding block 1351 to rotate through the meshing transmission of the second gear ring 1332 and the plurality of second gears 134, and then the material discharging rod 137 is extended into the material passing barrel 14 through the transmission of the eccentric column 135 and the connecting rod 136 to dredge the material, and the limiting constraint of the arc plate 138 and the eccentric column 135 makes the displacement distance of the material discharging rod 137 reciprocatingly extending into the material passing barrel 14 gradually increase within one cycle, so that the material discharging rod 137 can gradually loosen the food material in the material passing barrel 14, and avoid further tightening of the food material due to excessive force applied at one time;

[0058] In addition, a material guide assembly 24 is also provided in the material guide cylinder 242. With the help of the reciprocating swing of the material guide plate 245, the material at the position of the material guide cylinder 242 adjacent to the conveying box 22 is continuously kept loose, and the material discharge is smooth, so that the grain material can be discharged smoothly from the feed hopper 1 into the conveying box 22 after passing through the material cylinder 14 and the material guide cylinder 242 in sequence, thereby realizing all-round anti-blockage of material transportation between the feed hopper 1 and the conveying box 22.

[0059] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
