Description

Technical Field

[0001] This invention relates to the field of material conveying devices, specifically to a material conveying device for processing miscellaneous grains. Background Technology

[0002] Coarse grains generally refer to grain and legume crops other than the five major crops of rice, wheat, corn, soybeans, and potatoes. They mainly include: sorghum, millet, buckwheat, oats, barley, foxtail millet, foxtail millet, Job's tears, amaranth, as well as kidney beans, mung beans, adzuki beans, broad beans, peas, cowpeas, lentils, black beans, etc. They are characterized by short growing seasons, small planting areas, special planting regions, and low yields. They generally contain rich nutrients. Various equipment is required in the processing of coarse grains, including material conveying devices.

[0003] Publication No. CN118744869A discloses a feeding device and method for processing miscellaneous grains. By setting up a support mechanism, the conveyor belt can be driven to retract downwards, reducing its height and facilitating movement. Simultaneously, this support mechanism, in conjunction with connecting components and a power component, can synchronously drive the feeding hopper to move upwards with the conveyor belt during its retraction, and drive the power component to follow the conveyor belt's movement. This allows the feeding hopper and power component to adapt synchronously to changes in the conveyor belt's operating state, preventing them from obstructing the conveyor belt's movement and ensuring its normal retraction and retraction. Furthermore, after switching to the extended state, the conveyor belt can be immediately put into use, making it very convenient. However, this patent still has the following problems in actual use:

[0004] Although this grain processing conveying device can drive the conveyor belt to retract downwards by setting up a support mechanism to reduce the height of the conveyor belt and facilitate its movement, the center of gravity will shift after the height of the conveyor belt is adjusted because the length of the conveyor belt is fixed. Since the size of the base is fixed, when the height of the conveyor belt changes and the center of gravity shifts, the base will become unstable and sway when conveying a large amount of grain at a height. In severe cases, the entire device may tip over, which is detrimental to the stability of grain conveying. At the same time, when using the conveyor belt to convey grain, due to the high conveying height, grain may slip off the conveyor belt, thus affecting the efficiency of grain conveying.

[0005] Therefore, a conveying device for processing miscellaneous grains is proposed to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a conveying device for processing miscellaneous grains, in order to solve the problems mentioned in the background art. Because the length of the conveyor belt is fixed, its center of gravity will shift after the height of the conveyor belt is adjusted, while the size of the base is fixed. Therefore, when the height of the conveyor belt changes and its center of gravity shifts, when a large amount of miscellaneous grains are conveyed to a higher position, it will cause the base to become unstable and sway. In severe cases, it will cause the entire device to tip over, which is detrimental to the stability of grain conveying. At the same time, when using the conveyor belt to convey miscellaneous grains, due to the high conveying height, the miscellaneous grains will slip off the conveyor belt, thereby affecting the efficiency of grain conveying.

A lifting motor is fixedly installed on one side of the inner side of the second sprocket limit cover, and a second sprocket transmission assembly is fixedly connected to the output end of the lifting motor.

[0018] Preferably, the conveying mechanism includes a conveying pipe, a feed hopper is fixedly installed on one side of the top of the conveying pipe, a discharge pipe is fixedly installed on the bottom side of the conveying pipe away from the feed hopper, a conveying motor is fixedly installed on the side of the conveying pipe close to the feed hopper, a conveying rotating rod is fixedly connected to the output end of the conveying motor, and a conveying auger is fixedly installed on the outside of the conveying rotating rod.

[0019] Preferably, a screening screen is fixedly installed on the inner bottom of the conveying pipe, and the cleaning box is fixedly installed on the outer bottom of the conveying pipe. The cleaning box is rotatably connected to the connecting rotating support, the supporting cylinder and the top rotating support respectively. A torsion spring hinge is symmetrically installed on one side of the cleaning box, and a sealing plate is rotatably connected to the outer side of the two torsion spring hinges. A triangular bracket is fixedly installed on the outer side of the conveying pipe and the cleaning box, and a chain limiting groove is opened inside the triangular bracket.

[0020] Preferably, a drive sprocket is fixedly installed at the end of the conveying rotating rod, a conveying chain is meshed with the outer side of the drive sprocket, driven sprockets are symmetrically meshed with the inner bottom of the conveying chain, a cleaning reciprocating screw is fixedly installed on one side of each of the two driven sprockets, a screw sleeve is fitted on the outer side of each of the two cleaning reciprocating screws, a connecting bracket is symmetrically installed on the outer side of each of the two screw sleeves, an arc-shaped cleaning brush is fixedly installed on the top of each connecting bracket, the arc-shaped cleaning brush is in close contact with the bottom of the screening screen, a rotating gear is rotatably connected to one side of each of the two screw sleeves, a cleaning roller is fixedly installed between the two rotating gears, a meshing rack is meshed with the top of each of the two rotating gears, and the meshing racks are symmetrically installed inside the cleaning chamber.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: When the angle of the conveying mechanism is adjusted, the bottom rotating support moves horizontally, simultaneously driving the supporting connecting block and the first vertical rod to move. At the same time, the limiting slider moves inside the translational sliding groove. The first vertical rod drives the horizontal connecting rod and the second vertical rod to move. Under the action of the first universal wheel, the support sleeve can move. Due to the angle adjustment of the conveying mechanism causing its center of gravity to shift, the conveying machine can achieve [the desired movement] by moving the first universal wheel and the support sleeve in the same direction as the conveying mechanism. The stable support structure prevents the entire conveying equipment from becoming unstable and tipping over, improving the stability of the conveying equipment when transporting grains. The lead screw sleeve drives the connecting bracket and the arc-shaped cleaning brush to move, cleaning the bottom of the screening screen and preventing clogging, which would affect the screening effect. Simultaneously, the movement of the lead screw sleeve drives the rotating gear and the cleaning roller. Utilizing the meshing connection between the rotating gear and the gear rack, the cleaning roller rotates, improving its cleaning effect and allowing the screened grain fragments to be discharged from the sealing plate. The specific details are as follows:

[0022] 1. By setting up a stable support mechanism, not only can the tilting motor drive the first sprocket transmission assembly and the tilting threaded rod to rotate, causing the two tilting threaded sleeves to move on the outer threads of the tilting threaded rod, but the tilting threaded sleeves also drive the bottom rotating support and the tilting rotating rod to rotate. Under the action of the top rotating support and the connecting rotating support, the angle of the conveying mechanism can be adjusted. At the same time, the support cylinder is used to achieve stable support for the conveying mechanism, improving the stability of grain conveying. When the angle of the conveying mechanism is adjusted, the bottom rotating support moves horizontally, driving the support connecting block and the first vertical rod to move. Simultaneously, the limit slider moves inside the translational slide, and the first vertical rod drives the horizontal connecting rod and the second vertical rod to move. Under the action of the first universal wheel, the support sleeve can move. Because the angle adjustment of the conveying mechanism causes its center of gravity to shift, the first universal wheel and the support sleeve move in the same direction as the conveying mechanism, achieving stable support for the conveying mechanism and avoiding the phenomenon of the entire conveying equipment becoming unstable and tipping over, thus improving the efficiency of conveying. The stability of the conveying equipment for transporting grains is achieved by utilizing the sliding connection between the second vertical rod and the support sleeve. This allows for the extension and retraction adjustment of the support sleeve, which is then fixed by a locking knob. Starting the lifting motor drives the second sprocket transmission assembly and the lifting bidirectional threaded rod to rotate. This causes the lifting threaded sleeve to move outside the lifting bidirectional threaded rod, simultaneously rotating the lifting rotating rod. At the same time, the lifting sliding sleeve moves outside the lifting sliding rod. Under the action of the connecting spring, the distance between the lifting base and the lifting top frame can be adjusted, facilitating the adjustment of the height of the conveying mechanism. The second universal wheel allows for the movement of the entire conveying equipment, facilitating the transport of grains. Because the conveying mechanism is relatively long, it facilitates transporting grains to different heights for processing or storage. The stable support mechanism, to save space and avoid impacting other equipment during transport, is shorter in length. Therefore, by utilizing the synchronous adjustment of the second vertical rod and the support sleeve with the conveying mechanism, stable support of the entire conveying device can be achieved, improving the stability of grain transport.

[0023] 2. By setting up a conveying mechanism, not only can grains be put into the feed hopper, but starting the conveyor motor also drives the conveyor rotating rod and the conveyor auger to rotate. Utilizing the structural characteristics of the conveyor auger, the grains can be conveyed. At the same time, the screening screen can screen the grains, separating some broken grains and thus improving the quality of the grains. The screened grains are discharged through the discharge pipe. When the conveyor rotating rod rotates, it drives the drive sprocket to rotate. Utilizing the meshing connection between the drive sprocket, the conveyor chain, and the driven sprocket, and with the limiting action of the chain limiting groove, the grains are effectively controlled. The driven sprocket drives the cleaning reciprocating screw to rotate, while the screw sleeve moves back and forth on the outside of the cleaning reciprocating screw. The screw sleeve drives the connecting bracket and the arc-shaped cleaning brush to move, which can clean the bottom of the screening screen and avoid clogging of the screening screen, thus affecting the screening effect of the grains. At the same time, the movement of the screw sleeve drives the rotating gear and the cleaning roller to move. Utilizing the meshing connection between the rotating gear and the meshing rack, the cleaning roller can be rotated, thereby improving the cleaning effect of the cleaning roller and discharging the screened broken grains from the sealing plate.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-4The present invention provides a technical solution: a conveying device for processing miscellaneous grains, comprising a stabilizing support mechanism 1 and a lifting top frame 121 installed at the bottom of the stabilizing support mechanism 1. A conveying mechanism 2 is provided at the top of the stabilizing support mechanism 1, and a cleaning box 208 is provided at the bottom of the conveying mechanism 2. The stabilizing support mechanism 1 includes an inclined base 101, a connecting rotating support 102 is rotatably connected to one side of the top of the inclined base 101, and a supporting cylinder 103 is rotatably connected to the side of the inclined base 101 away from the connecting rotating support 102. A first sprocket limiting cover 104 is fixedly installed at one end of the inclined base 101 near the supporting cylinder 103. An inclined motor 105 is fixedly installed on one side of the inside of the first sprocket limiting cover 104. A first sprocket transmission assembly 106 is fixedly connected to the output end of the inclined motor 105, and inclined threaded rods are symmetrically installed on the outside of the first sprocket transmission assembly 106. 107. Inclined threaded sleeves 108 are threadedly connected to the outer sides of two inclined threaded rods 107. Bottom rotating supports 109 are fixedly installed on the top of each of the two inclined threaded sleeves 108. An inclined rotating rod 110 is rotatably connected inside the bottom rotating support 109. A top rotating support 111 is rotatably connected to the end of the inclined rotating rod 110 away from the bottom rotating support 109. The inclined motor 105 drives the first sprocket transmission assembly 106 and the inclined threaded rods 107 to rotate. As the two inclined threaded sleeves 108 move along the outer threads of the inclined threaded rods 107, the inclined threaded sleeves 108 drive the bottom rotating support 109 and the inclined rotating rod 110 to rotate. Under the action of the top rotating support 111 and the connecting rotating support 102, the angle of the conveying mechanism 2 can be adjusted. At the same time, the support cylinder 103 is used to achieve stable support for the conveying mechanism 2, thereby improving the stability of grain conveying.

[0038] Please see Figures 1-5The inclined base 101 has symmetrically arranged translational grooves 112 inside. A support connecting block 113 is fixedly installed between two inclined threaded sleeves 108. A first vertical rod 114 is fixedly installed at the bottom of the support connecting block 113. Limiting sliders 115 are symmetrically installed on the outer side of the first vertical rod 114. The limiting sliders 115 are slidably connected to the inclined base 101 through the translational grooves 112. A horizontal connecting rod 116 is fixedly installed at the bottom of the first vertical rod 114. A second vertical rod 117 is fixedly installed on the side of the bottom of the horizontal connecting rod 116 away from the first vertical rod 114. A support sleeve 118 is slidably connected to the outer side of the second vertical rod 117. A first universal wheel 11 is fixedly installed at the bottom of the support sleeve 118. 9. When the angle of the conveying mechanism 2 is adjusted, the bottom rotating support 109 moves horizontally, driving the support connecting block 113 and the first vertical rod 114 to move. At the same time, the limiting slider 115 moves inside the translational slide 112. The first vertical rod 114 drives the horizontal connecting rod 116 and the second vertical rod 117 to move. Under the action of the first universal wheel 119, the support sleeve 118 can move. Due to the angle adjustment of the conveying mechanism 2, its center of gravity shifts. By moving the first universal wheel 119 and the support sleeve 118 in the same direction as the conveying mechanism 2, the conveying mechanism 2 can be stably supported, avoiding the phenomenon of the entire conveying equipment becoming unstable and tipping over, and improving the stability of the conveying equipment in conveying grains.

[0039] Please see Figures 5-7A locking knob 120 is threadedly connected to one side of the top of the support sleeve 118. The locking knob 120 is in contact with the surface of the second vertical rod 117. The lifting frame 121 is symmetrically installed at the bottom of the inclined base 101. A second sprocket limit cover 122 is fixedly installed at the end of the two lifting frames 121. A lifting motor 123 is fixedly installed inside one side of the second sprocket limit cover 122. A second sprocket transmission assembly 124 is fixedly connected to the output end of the lifting motor 123. A lifting bidirectional threaded rod 125 is symmetrically installed on the outside of the second sprocket transmission assembly 124. Two lifting double-threaded rods 125 are symmetrically threaded with lifting threaded sleeves 126 on their outer sides. A lifting rotating rod 127 is rotatably connected to the bottom of the lifting threaded sleeve 126. A lifting sliding sleeve 128 is rotatably connected to the bottom of the lifting rotating rod 127. A lifting sliding rod 129 is slidably connected inside the lifting sliding sleeve 128. A connecting spring 130 is fixedly installed on one side of the lifting sliding sleeve 128. A lifting base 131 is fixedly installed on the outer side of the lifting sliding rod 129. Second universal wheels 132 are symmetrically installed at the bottom of both lifting bases 131, utilizing the second vertical... The sliding connection between rod 117 and support sleeve 118 allows for the telescopic adjustment of support sleeve 118, which is then fixed by locking knob 120. Starting lifting motor 123 drives second sprocket transmission assembly 124 and lifting bidirectional threaded rod 125 to rotate. This causes lifting threaded sleeve 126 to move outside of lifting bidirectional threaded rod 125, simultaneously driving lifting rotating rod 127 to rotate. At the same time, lifting sliding sleeve 128 moves outside of lifting sliding rod 129. Under the action of connecting spring 130, the lifting base frame 131 and lifting top frame 121 can be connected. The adjustable distance between the conveying mechanism 2 facilitates the adjustment of its height. The second caster 132 enables the movement of the entire conveying equipment, facilitating the conveying of grains. Due to the relatively long length of the conveying mechanism 2, it is convenient to transport grains to different heights for processing or storage. In order to save space and avoid affecting other equipment during conveying, the stable support mechanism 1 is relatively short. Therefore, by using the second vertical rod 117 and the support sleeve 118 to synchronously adjust with the conveying mechanism 2, the stable support of the entire conveying device can be achieved, improving the stability of grain conveying.

[0040] Please see Figure 1 , Figures 4-8The conveying mechanism 2 includes a conveying pipe 201. A feed hopper 202 is fixedly installed on one side of the top of the conveying pipe 201. A discharge pipe 203 is fixedly installed on the bottom side of the conveying pipe 201 away from the feed hopper 202. A conveying motor 204 is fixedly installed on the side of the conveying pipe 201 near the feed hopper 202. A conveying rotating rod 205 is fixedly connected to the output end of the conveying motor 204. A conveying auger 206 is fixedly installed on the outside of the conveying rotating rod 205. A screening screen 207 is fixedly installed on the inner side of the bottom of the conveying pipe 201. A cleaning box 208 is fixedly installed on... The bottom outer side of the conveying pipe 201 and the cleaning box 208 are respectively rotatably connected to the connecting rotating support 102, the supporting cylinder 103 and the top rotating support 111. When the grains are put into the feed hopper 202, the conveying motor 204 is started to drive the conveying rotating rod 205 and the conveying auger 206 to rotate. The structural characteristics of the conveying auger 206 can realize the conveying of the grains. At the same time, the screening screen 207 can realize the screening of the grains, which can screen out some broken grains, thereby improving the quality of the grains. The screened grains are discharged through the discharge pipe 203.

[0041] Please see Figures 8-11A torsion spring hinge 209 is symmetrically installed on one side of the cleaning chamber 208. A sealing plate 210 is rotatably connected to the outer side of the two torsion spring hinges 209. A triangular bracket 211 is fixedly installed on the outer side of the conveying pipe 201 and the cleaning chamber 208. A chain limiting groove 212 is opened inside the triangular bracket 211. A drive sprocket 213 is fixedly installed at the end of the conveying rotating rod 205. A conveying chain 214 is meshed on the outer side of the drive sprocket 213. A driven sprocket 215 is symmetrically meshed on the inner bottom side of the conveying chain 214. Two driven sprockets 215 are fixedly mounted on one side with cleaning reciprocating screws 216. Screw sleeves 217 are fitted on the outer sides of the two cleaning reciprocating screws 216. Connecting brackets 218 are symmetrically mounted on the outer sides of the two screw sleeves 217. Arc-shaped cleaning brushes 219 are fixedly mounted on the top of the connecting brackets 218. The arc-shaped cleaning brushes 219 are in close contact with the bottom of the screening screen 207. Rotating gears 220 are rotatably connected to one side of each screw sleeve 217. Cleaning rollers 221 are fixedly mounted between the two rotating gears 220. Each gear 220 has a meshing rack 222 meshing at its top. The meshing racks 222 are symmetrically installed inside the cleaning housing 208. When the conveying rotating rod 205 rotates, it drives the driving sprocket 213 to rotate. Utilizing the meshing connection between the driving sprocket 213, the conveying chain 214, and the driven sprocket 215, and under the limiting action of the chain limiting groove 212, the driven sprocket 215 drives the cleaning reciprocating screw 216 to rotate. At the same time, the screw sleeve 217 reciprocates outside the cleaning reciprocating screw 216. 7 drives the connecting bracket 218 and the arc-shaped cleaning brush 219 to move, which can clean the bottom of the screening screen 207 and avoid clogging of the screening screen 207, thereby affecting the screening effect of the grains. At the same time, the movement of the screw sleeve 217 drives the rotating gear 220 and the cleaning roller 221 to move. Utilizing the meshing connection between the rotating gear 220 and the meshing rack 222, the cleaning roller 221 can be rotated, thereby improving the cleaning effect of the cleaning roller 221 and discharging the screened grains from the sealing plate 210.

[0042] Working principle: Before using this type of conveying equipment for grain processing, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 11As shown, firstly, the grains are placed into the feed hopper 202. The conveyor motor 204 is started, driving the conveyor rotating rod 205 and the conveyor auger 206 to rotate. Utilizing the structural characteristics of the conveyor auger 206, the grains can be conveyed. Simultaneously, the screening screen 207 can screen the grains, removing some broken grains and thus improving the quality of the grains. The screened grains are discharged through the discharge pipe 203. When the conveyor rotating rod 205 rotates, it drives the drive sprocket 213 to rotate. Utilizing the meshing connection between the drive sprocket 213, the conveyor chain 214, and the driven sprocket 215, and under the limiting action of the chain limiting groove 212, the driven sprocket 215... 5 drives the cleaning reciprocating screw 216 to rotate, and at the same time the screw sleeve 217 moves back and forth on the outside of the cleaning reciprocating screw 216. The screw sleeve 217 drives the connecting bracket 218 and the arc-shaped cleaning brush 219 to move, which can clean the bottom of the screening screen 207 and avoid the phenomenon of clogging of the screening screen 207, thereby affecting the screening effect of grains. At the same time, the movement of the screw sleeve 217 drives the rotating gear 220 and the cleaning roller 221 to move. Utilizing the meshing connection between the rotating gear 220 and the meshing rack 222, the cleaning roller 221 can be rotated, thereby improving the cleaning effect of the cleaning roller 221 and discharging the screened broken grains from the sealing plate 210.

[0043] Secondly, the tilting motor 105 drives the first sprocket transmission assembly 106 and the tilting threaded rod 107 to rotate. This causes the two tilting threaded sleeves 108 to move along the outer threads of the tilting threaded rod 107, simultaneously driving the bottom rotating support 109 and the tilting rotating rod 110 to rotate. Under the action of the top rotating support 111 and the connecting rotating support 102, the angle of the conveying mechanism 2 can be adjusted. Simultaneously, the support cylinder 103 provides stable support for the conveying mechanism 2, improving the stability of grain conveying. When the angle of the conveying mechanism 2 is adjusted, the bottom rotating support 109 moves horizontally simultaneously... The first vertical rod 114 moves while the supporting connecting block 113 and the first vertical rod 114 move. At the same time, the limiting slider 115 moves inside the translational slide 112. The first vertical rod 114 drives the horizontal connecting rod 116 and the second vertical rod 117 to move. Under the action of the first universal wheel 119, the supporting sleeve 118 can move. Due to the angle adjustment of the conveying mechanism 2, its center of gravity shifts. By moving the first universal wheel 119 and the supporting sleeve 118 in the same direction as the conveying mechanism 2, the conveying mechanism 2 can be stably supported, avoiding the phenomenon of the entire conveying equipment becoming unstable and tipping over, and improving the stability of the conveying equipment in conveying grains.

[0044] Secondly, by utilizing the sliding connection between the second vertical rod 117 and the support sleeve 118, the extension and retraction of the support sleeve 118 can be achieved, and it can be fixed by the locking knob 120. Starting the lifting motor 123 drives the second sprocket transmission assembly 124 and the lifting bidirectional threaded rod 125 to rotate, causing the lifting threaded sleeve 126 to move outside the lifting bidirectional threaded rod 125 while simultaneously driving the lifting rotating rod 127 to rotate. At the same time, the lifting sliding sleeve 128 moves outside the lifting sliding rod 129. Under the action of the connecting spring 130, the lifting base frame 131 and the lifting top frame can be connected. Adjusting the distance between 121 facilitates adjusting the height of the conveying mechanism 2. The second universal wheel 132 enables the movement of the entire conveying equipment, facilitating the conveying of grains. Since the conveying mechanism 2 is relatively long, it is convenient to transport grains to different heights for processing or storage. In order to save space and avoid affecting other equipment during conveying, the stabilizing support mechanism 1 is relatively short. Therefore, by using the second vertical rod 117 and the support sleeve 118 to synchronously adjust with the conveying mechanism 2, the entire conveying device can be stably supported, improving the stability of grain conveying.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
