Description

Technical Field

[0001] The invention relates to the technical field of food processing, in particular to a lifting device for processing selenium-enriched millet. Background Art

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

[0003] Announcement No. CN220181824U discloses a bucket-type grain elevator that is easy to adjust. In actual use, it is easy to drive the elevator to rotate and adjust the height of the discharge port of the elevator, so as to facilitate the lifting and discharging of materials at positions of different heights, which is convenient for people to use. In actual use, the discharge anti-blocking component solves the problem that materials easily adhere to the discharge pipe or discharge plate during unloading. If they are not cleaned, the discharge port will be blocked, affecting the grain transportation. By providing a conveying motor, the conveying motor can drive one of the drive rollers to rotate, and one of the drive rollers drives the other drive roller to rotate through the transmission belt. At this time, the transmission belt can drive the grain bucket to transport materials. However, the following problems still exist in the actual use of this patent:

[0004] Although the easy-to-adjust bucket-type grain elevator 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, the material conveying amount needs to be strictly controlled when using the conveying bucket for lifting materials. When there is too much material, the burden on the conveying bucket will increase, affecting the service life of the conveying bucket. When using a conveyor belt or a screw conveyor to convey selenium-rich millet, since the conveyor belt cannot achieve vertical lifting, the conveying of millet is subject to certain restrictions. 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 spiral blades, the spiral surface and the material, and the machine trough and the material. Therefore, the power consumption of the screw conveyor is usually high, which increases the production cost to a certain extent. Due to severe friction, the mechanical parts of the screw conveyor wear faster, which will lead to increased equipment maintenance costs. In addition, the material may be subjected to a greater crushing effect during the transportation process.

[0005] Therefore, a lifting device for processing selenium-rich millet is proposed to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a lifting device for processing selenium-rich millet, so as to solve the problem raised in the above background technology that when using a conveyor bucket for conveying, the weight that the conveyor bucket can bear at one time is limited, and the material conveying amount needs to be strictly controlled when using the conveyor bucket for lifting materials.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: when there is a lot of selenium-rich millet, the second cover plate is unfolded under the action of the second hinge, and the excess selenium-rich millet falls to the bottom through the second cover plate, so as to avoid a large amount of selenium-rich millet, which leads to an excessive weight of the lifting bucket, thereby affecting the lifting and transportation of the selenium-rich millet. The first lifting motor is used to drive the first lifting rotating rod and the bevel gear transmission assembly to rotate, so that the bevel gear transmission assembly drives the first lifting threaded rod to rotate, and at the same time, the first lifting threaded sleeve drives the discharge pipe and the meshing rack to move up and down. The meshing connection between the meshing rack and the rotating gear is used to realize the rotation of the rotating baffle, and the rotating baffle is rotated to an inclined state, so as to facilitate the introduction of the selenium-rich millet into the discharge pipe for lifting and transportation of the selenium-rich millet. The specific contents are as follows:

[0022] 1. By setting up the lifting mechanism, not only can the lifting motor be used to drive the first lifting roller and the first sprocket body to rotate, but also the meshing connection between the first sprocket body, the transmission chain and the second sprocket body can be used to make the second sprocket body drive the second lifting roller to rotate. The transmission connection between the first lifting roller, the second lifting roller and the transmission belt can be used to make the transmission belt rotate while driving the lifting bucket to rotate, thereby realizing the lifting and conveying function of selenium-rich millet. When the selenium-rich millet is accumulated on the arc baffle, the gravity of the selenium-rich millet is used to make the support block slide under the action of the feed sliding rod and the feed sliding sleeve, so that the selenium-rich millet falls into the feed through the slot. When the selenium-rich millet is stored in the lifting bucket, the second cover plate is unfolded under the action of the second hinge, and the excess selenium-rich millet falls to the bottom through the second cover plate, so as to avoid the excessive weight of the lifting bucket due to the large amount of selenium-rich millet, thereby affecting the lifting and transportation of the selenium-rich millet and increasing the burden on the first sprocket body, the transmission chain and the second sprocket body, causing the transmission chain to break, 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, the first hinge and the guide cover plate are acted upon by their own gravity, so that the guide cover plate rotates a certain angle, and the selenium-rich millet stored in the lifting bucket is discharged under the action of gravity.

[0023] 2. By setting up the lifting mechanism, not only can the first lifting motor be used to drive the first lifting rotating rod and the bevel gear transmission assembly to rotate, so that the bevel gear transmission assembly drives the first lifting threaded rod to rotate, but the first lifting threaded sleeve drives the discharge pipe and the meshing rack to move up and down. By utilizing the characteristics 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, which is convenient for introducing the selenium-rich millet into the discharge pipe and lifting and conveying the selenium-rich millet. When the meshing rack is separated from the rotating gear, the torsion spring is provided inside the rotating gear, which can realize the reset of the rotating baffle and rotate the rotating baffle to a horizontal state, thereby sealing the discharge frame, and can be based on the discharge. The height of the discharge pipe can be adjusted at will, so that the selenium-rich millet can be transported to different heights for subsequent storage or processing. By starting the second lifting motor to drive the sprocket transmission assembly and the lifting two-way threaded rod to rotate, the second lifting threaded sleeve moves relatively on the outside of the lifting two-way threaded rod while the second lifting rotating rod is rotated. 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 base frame and the lifting top frame. The height of the entire lifting box can be adjusted, which is convenient for lifting and conveying selenium-rich millet. By turning the adjusting knob, the supporting threaded rod is driven to rotate, and the supporting base is lifted and moved, thereby adapting to uneven ground and improving the stability of lifting and conveying selenium-rich millet.

At the same time, the lifting sliding sleeve 223 slides relative to the outside of the lifting sliding rod 224, thereby adjusting the distance between the lifting frame 225 and the lifting top frame 216, and can adjust the height of the entire lifting box 201, which is convenient for lifting and conveying selenium-rich millet. By turning the adjusting knob 227, the support threaded rod 226 is driven to rotate, so that the support base 228 is lifted and moved, thereby adapting to uneven ground and improving the stability of lifting and conveying selenium-rich millet.

[0042] Working principle: Before using this lifting device for selenium-rich millet processing, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 11As shown, first, the lifting motor 101 is used to drive the first lifting roller 102 and the first sprocket body 103 to rotate, and the meshing connection between the first sprocket body 103, the transmission chain 104 and the second sprocket body 105 is used to make the second sprocket body 105 drive the second lifting roller 106 to rotate, and the transmission connection between the first lifting roller 102, the second lifting roller 106 and the transmission belt 107 is used to make the transmission belt 107 rotate while driving the lifting bucket 109 to rotate, thereby realizing the lifting and conveying function of the selenium-rich millet. When the selenium-rich millet is accumulated on the arc baffle 117, the gravity of the selenium-rich millet is used to slide on the feeding slide. Under the action of the moving rod 113 and the feeding sliding sleeve 114, the support block 116 slides, so that the selenium-rich millet falls into the lifting bucket 109 through the through groove 112 for storage. When there is a lot of selenium-rich millet, the second cover plate 119 is unfolded under the action of the second hinge 118, and the excess selenium-rich millet falls to the bottom through the second cover plate 119, so as to avoid a large amount of selenium-rich millet causing the lifting bucket 109 to be too heavy, thereby affecting the lifting and transportation 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, causing the transmission chain 104 to break, which is not conducive to the normal use of the entire lifting device.

[0043] Secondly, when the lifting bucket 109 moves to one side of the discharge pipe 212, the first hinge 110 and the guide cover 111 are rotated to a certain angle under the action of their own gravity, and the selenium-rich millet stored in 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, and 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, and the meshing rack 213 and the rotating gear 204 are used to engage with each other. The characteristics of the meshing connection can realize the rotation of the rotating baffle 205, and the rotating baffle 205 is rotated to an inclined state, which is convenient for introducing the selenium-rich millet into the discharge pipe 212 for lifting and conveying the selenium-rich millet. When the meshing rack 213 is separated from the rotating gear 204, since a torsion spring is provided inside the rotating gear 204, the rotating baffle 205 can be reset, and the rotating baffle 205 is rotated to a horizontal state, thereby sealing the discharge frame 203. The discharge pipe 212 can be arbitrarily adjusted according to the height of the discharge, which is convenient for conveying the selenium-rich millet to different heights and facilitating subsequent storage or processing.

[0044] Finally, by starting the second lifting motor 218, the sprocket transmission assembly 219 and the lifting two-way threaded rod 220 are driven to rotate, so that the second lifting threaded sleeve 221 moves relative to the outside of the lifting two-way threaded rod 220, and at the same time, the second lifting rotating rod 222 is mobilized to rotate, and at the same time, the lifting sliding sleeve 223 slides relative to the outside of the lifting sliding rod 224, thereby adjusting the distance between the lifting base frame 225 and the lifting top frame 216, and the height of the entire lifting box 201 can be adjusted, which is convenient for lifting and conveying selenium-rich millet. By turning the adjusting knob 227, the supporting threaded rod 226 is driven to rotate, and the supporting base 228 is lifted and moved, thereby adapting to uneven ground and improving the stability of lifting and conveying selenium-rich millet.
