Description

Technical Field

[0001] The present invention relates to the technical field of food processing, and specifically to a lifting device for processing selenium-rich millet. Background Art

[0002] Selenium-rich millet is a nutritious grain, containing a large amount of protein, fat, carbohydrates, minerals and vitamins. Among them, selenium is the main characteristic of selenium-rich millet: it is an essential trace element with various biological activities such as antioxidant, immune enhancement, and cancer prevention. In addition, millet is also rich in dietary fiber, which helps to improve intestinal health and promote digestion. Selenium-rich millet can be used to cook porridge, steam rice, grind into powder, etc.

[0003] Publication No. CN220181824U discloses a bucket-type grain elevator that is easy to adjust. In actual use, it can facilitate the rotation of the elevator and adjust the height of the discharge port of the elevator, so as to facilitate the lifting and discharging of positions at different heights, which is convenient for people to use. Moreover, in actual use, through the discharge anti-blocking component, the problem that when discharging, materials are likely to adhere to the discharge pipe or discharge plate, and if not cleaned, it will block the discharge port and affect the grain transportation is solved. By setting a conveying motor, the conveying motor can drive one of the driving roller wheels to rotate, and one of the driving roller wheels drives the other driving roller wheel to rotate through a transmission belt. At this time, the transmission belt can drive the grain bucket to convey materials. However, the following problems still exist in the actual use process of this patent: Although the bucket-type grain elevator that is easy to adjust can realize the function of lifting and conveying materials, when using the conveying bucket for conveying, since the weight that the conveying bucket can bear at one time is limited, it is necessary to strictly control the conveying volume of materials when using the conveying bucket for lifting materials. When there is too much material, it will increase the burden on the conveying bucket and affect the service life of the conveying bucket. When using a conveyor belt or a screw conveyor for conveying selenium-rich millet, since the conveyor belt cannot achieve vertical lifting, it is limited to a certain extent when conveying millet. When using a screw conveyor for conveying, the screw conveyor will generate greater resistance during operation. These resistances mainly come from the friction between the machine trough and the screw blade, the screw surface and the material, and the machine trough and the material. Therefore, the power consumption of the screw conveyor is usually relatively high, which increases the production cost to a certain extent. Due to serious friction, the wear speed of the parts of the screw conveyor is relatively fast, which will lead to an increase in equipment maintenance costs. In addition, the materials may be subjected to a greater crushing effect during the conveying process.

[0004] Therefore, a lifting device for processing selenium-rich millet is proposed to solve the problems mentioned above. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: For a lifting device for selenium-rich millet processing, when there is a large amount of selenium-rich millet, under the action of the second hinge, the second cover plate is unfolded, and the excess selenium-rich millet falls to the bottom through the second cover plate, avoiding the situation that the large amount of selenium-rich millet causes the excessive weight of the lifting bucket, thus affecting the lifting and conveying of selenium-rich millet. By driving the first lifting rotating rod and the bevel gear transmission assembly to rotate with the first lifting motor, the bevel gear transmission assembly drives the first lifting threaded rod to rotate. At the same time, the first lifting threaded sleeve drives the discharge pipe and the meshing rack to move up and down. By using the characteristic of the meshing connection between the meshing rack and the rotating gear, the rotation of the rotating baffle can be realized, and the rotating baffle is rotated to an inclined state, facilitating the introduction of selenium-rich millet to the discharge pipe for the lifting and conveying of selenium-rich millet. The specific content is as follows: 1. By setting the lifting mechanism, not only can the lifting motor drive the first lifting roller and the first sprocket body to rotate, and by using the meshing connection characteristics among the first sprocket body, the transmission chain and the second sprocket body, the second sprocket body drives the second lifting roller to rotate. By using the transmission connection characteristics among the first lifting roller, the second lifting roller and the transmission belt, when the transmission belt rotates, it drives the lifting bucket to rotate, thus realizing the lifting and conveying function of selenium-rich millet. When the selenium-rich millet accumulates on the arc-shaped baffle, under the action of the gravity of the selenium-rich millet and the feeding sliding rod and the feeding sliding sleeve, the support block slides, and the selenium-rich millet falls into the lifting bucket through the through groove for storage. When there is a large amount of selenium-rich millet, under the action of the second hinge, the second cover plate is unfolded, and the excess selenium-rich millet falls to the bottom through the second cover plate, avoiding the situation that the large amount of selenium-rich millet causes the excessive weight of the lifting bucket, thus affecting the lifting and conveying of selenium-rich millet, and at the same time increasing the burden on the first sprocket body, the transmission chain and the second sprocket body, resulting in the phenomenon of the transmission chain breaking, which is not conducive to the normal use of the entire lifting device. When the lifting bucket moves to one side of the discharge pipe, under the action of the first hinge and the self-gravity of the guiding cover plate, the guiding cover plate rotates by a certain angle, and the selenium-rich millet stored in the lifting bucket is discharged under the action of gravity; 2. By setting up the lifting mechanism, not only can the first lifting motor drive the first lifting rotating rod and the bevel gear transmission assembly to rotate, causing the bevel gear transmission assembly to drive the first lifting threaded rod to rotate, while the first lifting threaded sleeve drives the discharge pipe and the meshing rack to move up and down. Utilizing the meshing connection between the meshing rack and the rotating gear, the rotation of the rotating baffle can be achieved, and the rotating baffle can be rotated to an inclined state, facilitating the introduction of selenium-rich millet to the discharge pipe for the lifting and conveying of selenium-rich millet. When the meshing rack is separated from the rotating gear, since a torsion spring is provided inside the rotating gear, the reset of the rotating baffle can be realized, causing the rotating baffle to rotate to a horizontal state, thereby blocking the discharge frame. The discharge pipe can be adjusted arbitrarily according to the discharge height, facilitating the conveyance of selenium-rich millet to different heights for subsequent storage or processing. By starting the second lifting motor to drive the sprocket transmission assembly and the lifting double-threaded rod to rotate, while the second lifting threaded sleeve moves relatively on the outside of the lifting double-threaded rod, the second lifting rotating rod is driven to rotate, and at the same time, the lifting sliding sleeve slides relatively on the outside of the lifting sliding rod, thereby adjusting the distance between the lifting bottom frame and the lifting top frame, enabling the adjustment of the height of the entire lifting box, facilitating the lifting and conveying of selenium-rich millet. By rotating the adjustment knob to drive the support threaded rod to rotate, the support base moves up and down, thereby adapting to uneven ground and improving the stability of the lifting and conveying of selenium-rich millet.

A drive belt 107 is drivingly connected to the outside of the first lifting roller 102 and the second lifting roller 106. A first sprocket limit cover 108 is arranged outside the drive chain 104. One side of the top of the lifting hopper 109 is fixedly connected to the drive belt 107. The lifting motor 101 is used to drive the first lifting roller 102 and the first sprocket body 103 to rotate. By using the meshing connection characteristics among the first sprocket body 103, the drive chain 104 and the second sprocket body 105, the second sprocket body 105 drives the second lifting roller 106 to rotate. By using the driving connection characteristics among the first lifting roller 102, the second lifting roller 106 and the drive belt 107, the drive belt 107 rotates and drives the lifting hopper 109 to rotate at the same time, so as to realize the lifting and conveying function of selenium-rich millet.

[0020] Please refer to Figures 4 - 5 , on one side of the top of the lifting hopper 109, first hinges 110 are symmetrically installed. A material guiding cover plate 111 is rotatably connected to the outside of the two first hinges 110. A through groove 112 is opened on one side inside the material guiding cover plate 111. On the side of the material guiding cover plate 111 far from the through groove 112, feeding sliding rods 113 are symmetrically installed.

The support block 116 is slidably connected to the material guiding cover plate 111. When the lifting hopper 109 moves to one side of the discharge pipe 212, under the action of the self-gravity of the first hinge 110 and the material guiding cover plate 111, the material guiding cover plate 111 rotates by a certain angle, and the selenium-rich millet stored inside the lifting hopper 109 is discharged under the action of gravity.

[0021] Please refer to Figures 6 - 7, on one side of the bottom of the lifting bucket 109, second hinges 118 are symmetrically installed. On the outer sides of the two second hinges 118, a second cover plate 119 is rotatably connected. On the bottom of the lifting bucket 109 near the second hinges 118, support sleeves 120 are symmetrically installed. Inside each of the two support sleeves 120, a support spring 121 is fixedly installed. Inside the support spring 121, a spring telescopic rod 122 is arranged. At the ends of the spring telescopic rod 122 and the support spring 121, support sliding rods 123 are fixedly installed. At the end of the support sliding rod 123, a support slider 124 is fixedly installed. At the end of the support slider 124, a guiding inclined groove 125 is formed. When the selenium-rich millet accumulates on the arc-shaped baffle 117, due to the gravity of the selenium-rich millet, under the action of the feeding sliding rod 113 and the feeding sliding sleeve 114, the support block 116 slides, and the selenium-rich millet falls into the lifting bucket 109 through the through groove 112 for storage. When there is more selenium-rich millet, under the action of the second hinge 118, the second cover plate 119 unfolds, and the excess selenium-rich millet falls to the bottom through the second cover plate 119, preventing the excessive weight of the lifting bucket 109 caused by too much selenium-rich millet, which affects the lifting and conveying of the selenium-rich millet, and at the same time increasing the burden on the first sprocket body 103, the transmission chain 104, and the second sprocket body 105, resulting in the phenomenon of the transmission chain 104 breaking, which is not conducive to the normal use of the entire lifting device.

[0022] Please refer to Figure 1 , Figures 8 - 9, the lifting mechanism 2 includes a lifting box 201. The lifting motor 101 and the first sprocket limit cover 108 are both fixedly installed on the outside of the lifting box 201. One side of the bottom of the lifting box 201 is fixedly installed with a feed pipe 202. One side of the top of the lifting box 201 is fixedly installed with a discharge frame 203. A number of rotating gears 204 are rotatably connected to both sides inside the discharge frame 203. A rotating baffle 205 is fixedly installed between the two rotating gears 204. A lifting bracket 206 is fixedly installed on the outside of the lifting box 201 close to the discharge frame 203. One side of the bottom of the lifting bracket 206 is fixedly installed with a first lifting motor 207. The output end of the first lifting motor 207 is fixedly connected with a first lifting rotating rod 208. Conical gear transmission components 209 are fixedly installed at both ends of the first lifting rotating rod 208. First lifting threaded rods 210 are fixedly installed at the tops of the two conical gear transmission components 209. First lifting threaded sleeves 211 are symmetrically threaded on the outside of the two first lifting threaded rods 210. A discharge pipe 212 is fixedly installed between the first lifting threaded sleeves 211. Meshing racks 213 are symmetrically installed on one side of the discharge pipe 212. The meshing racks 213 are meshed with the rotating gears 204. A torsion spring is arranged inside the rotating gear 204. By driving the first lifting rotating rod 208 and the conical gear transmission component 209 to rotate by the first lifting motor 207, the conical gear transmission component 209 drives the first lifting threaded rod 210 to rotate. At the same time, the first lifting threaded sleeve 211 drives the discharge pipe 212 and the meshing rack 213 to move up and down. By using the characteristic of the meshing connection between the meshing rack 213 and the rotating gear 204, the rotation of the rotating baffle 205 can be realized, and the rotating baffle 205 is rotated to an inclined state, which is convenient for guiding the selenium-rich millet to the discharge pipe 212 for the lifting and conveying of the selenium-rich millet. When the meshing rack 213 is separated from the rotating gear 204, due to the torsion spring arranged inside the rotating gear 204, the reset of the rotating baffle 205 can be realized, and the rotating baffle 205 is rotated to a horizontal state, so as to block the discharge frame 203. The discharge pipe 212 can be adjusted arbitrarily according to the discharge height, which is convenient for conveying the selenium-rich millet to different heights and is convenient for subsequent storage or processing.

[0023] Please refer to Figures 8 - 11, the lifting plate 214 is fixedly installed at the bottom of the lifting box 201. An installation groove 215 is formed inside the lifting plate 214. Lifting top frames 216 are fixedly installed on both sides of the lifting plate 214. A second sprocket limit cover 217 is fixedly installed on one side of the two lifting top frames 216. A second lifting motor 218 is fixedly installed on one side inside the second sprocket limit cover 217. The output end of the second lifting motor 218 is fixedly connected to a sprocket transmission assembly 219. Lifting bidirectional threaded rods 220 are symmetrically installed on one side of the sprocket transmission assembly 219. Second lifting threaded sleeves 221 are symmetrically and threadedly connected to the outer sides of the two lifting bidirectional threaded rods 220. The bottom of the second lifting threaded sleeve 221 is rotatably connected to a second lifting rotating rod 222. The bottom of the second lifting rotating rod 222 is rotatably connected to a lifting sliding sleeve 223. A lifting sliding rod 224 is slidably connected inside the lifting sliding sleeve 223. A lifting bottom frame 225 is fixedly installed on the outer side of the lifting sliding rod 224. Support threaded rods 226 are threadedly connected to both sides inside the lifting bottom frame 225. An adjustment knob 227 is fixedly installed at the top of the support threaded rod 226. The bottom of the support threaded rod 226 is rotatably connected to a support base 228. By starting the second lifting motor 218 to drive the sprocket transmission assembly 219 and the lifting bidirectional threaded rods 220 to rotate, the second lifting threaded sleeves 221 move relatively on the outer sides of the lifting bidirectional threaded rods 220 while driving the second lifting rotating rods 222 to rotate. At the same time, the lifting sliding sleeves 223 slide relatively on the outer sides of the lifting sliding rods 224, thereby adjusting the distance between the lifting bottom frame 225 and the lifting top frames 216, and being able to adjust the height of the entire lifting box 201, facilitating the lifting and conveying of selenium-rich millet. By rotating the adjustment knob 227 to drive the support threaded rod 226 to rotate, the support base 228 moves up and down, thereby adapting to uneven ground and improving the stability of the lifting and conveying of selenium-rich millet.

[0024] Working principle: Before using this lifting device for selenium-rich millet processing, it is necessary to first check the overall situation of the device to ensure that it can work normally. According to Figure 1 - Figure 11As shown in the figure, first, the lifting motor 101 is used to drive the first lifting roller 102 and the first sprocket body 103 to rotate. By virtue of the meshing connection among the first sprocket body 103, the transmission chain 104 and the second sprocket body 105, the second sprocket body 105 drives the second lifting roller 106 to rotate. By virtue of the transmission connection among the first lifting roller 102, the second lifting roller 106 and the conveyor belt 107, the conveyor belt 107 rotates and drives the lifting bucket 109 to rotate at the same time, so that the lifting and conveying function of the selenium-rich millet can be realized. When the selenium-rich millet accumulates on the arc-shaped baffle 117, under the action of the gravity of the selenium-rich millet and the action of the feeding sliding rod 113 and the feeding sliding sleeve 114, the support block 116 slides, and the selenium-rich millet falls into the lifting bucket 109 through the through groove 112 for storage. When there is a large amount of selenium-rich millet, under the action of the second hinge 118, the second cover plate 119 unfolds, and the excess selenium-rich millet falls to the bottom through the second cover plate 119, avoiding the situation that too much selenium-rich millet causes the weight of the lifting bucket 109 to be too large, which affects the lifting and conveying of the selenium-rich millet, and at the same time increasing the burden on the first sprocket body 103, the transmission chain 104 and the second sprocket body 105, resulting in the phenomenon of the transmission chain 104 breaking, which is not conducive to the normal use of the entire lifting device.

[0025] Secondly, when the lifting bucket 109 moves to one side of the discharge pipe 212, under the action of the self-gravity of the first hinge 110 and the guide material cover plate 111, the guide material cover plate 111 rotates by a certain angle, and the selenium-rich millet stored inside the lifting bucket 109 is discharged under the action of gravity. The first lifting motor 207 is used to drive the first lifting rotating rod 208 and the bevel gear transmission assembly 209 to rotate, so that the bevel gear transmission assembly 209 drives the first lifting threaded rod 210 to rotate. At the same time, the first lifting thread sleeve 211 drives the discharge pipe 212 and the meshing rack 213 to move up and down. By virtue of the meshing connection between the meshing rack 213 and the rotating gear 204, the rotation of the rotating baffle 205 can be realized. The rotating baffle 205 is rotated to an inclined state, which is convenient for guiding the selenium-rich millet to the discharge pipe 212 for the lifting and conveying of the selenium-rich millet. When the meshing rack 213 is separated from the rotating gear 204, due to the torsion spring arranged inside the rotating gear 204, the reset of the rotating baffle 205 can be realized, and the rotating baffle 205 is rotated to a horizontal state, thereby blocking the discharge frame 203. The discharge pipe 212 can be adjusted arbitrarily according to the discharge height, which is convenient for conveying the selenium-rich millet to different heights and is convenient for subsequent storage or processing.

[0026] Finally, by starting the second lifting motor 218 to drive the sprocket transmission assembly 219 and the lifting bidirectional threaded rod 220 to rotate, the second lifting thread sleeve 221 moves relatively on the outside of the lifting bidirectional threaded rod 220 while driving the second lifting rotating rod 222 to rotate. At the same time, the lifting sliding sleeve 223 slides relatively on the outside of the lifting sliding rod 224, thereby adjusting the distance between the lifting bottom frame 225 and the lifting top frame 216, enabling the adjustment of the height of the entire lifting box 201, facilitating the lifting and conveying of selenium-rich millet. By rotating the adjustment knob 227 to drive the support threaded rod 226 to rotate, the support base 228 moves up and down, thereby adapting to uneven ground and improving the stability of the lifting and conveying of selenium-rich millet.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
