Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain processing technology, and in particular to a grain processing assembly line screening machine. Background Technology
[0002] With the continuous development of society and the continuous progress of science and technology, the technology related to grain processing is also constantly improving. In real life, after harvesting, grains often contain dust, sand, weeds and other impurities. Usually, a production line screening machine is used to screen the grains before processing to prevent impurities from mixing into the grains.
[0003] The patent document with publication number "CN216094744U" discloses a grain processing assembly line screening machine, including a frame and a connecting unit; the frame has evenly distributed springs on its upper surface, and the upper ends of the springs are fixedly connected to the lower surface of the screening box.
[0004] Although the aforementioned patent documents have solved the problem that excessive material is squeezed on one side when the screening box is tilted longitudinally, which is not conducive to screening and affects the screening quality, the following disadvantages still exist: when the upper and lower screen plates are blocked by impurities after long-term use, it is inconvenient to clean the upper and lower screen plates thoroughly, which can easily lead to a poor screening effect on grains and is not conducive to the use of the screening machine. Utility Model Content
[0005] The purpose of this utility model is to solve the following shortcomings in the prior art: when the upper and lower screen plates are blocked by impurities after long-term use, it is inconvenient to clean the upper and lower screen plates thoroughly, which easily leads to a poor screening effect on grains and is not conducive to the use of the screening machine. Therefore, a production line screening machine for grain processing is proposed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A grain processing assembly line screening machine includes a frame and a screening box mounted on the frame. A door is provided on one side of the screening box, and multiple support slide rails are fixedly connected to one side surface of the door. Two screen plates are arranged between the multiple support slide rails.
[0008] Mounting plates are fixedly connected to both sides of the box door. Two sliders are mounted on the back of the screening box via two springs. A bending rod is fixedly connected to each slider. A circular hole for connecting the bending rod is provided on each mounting plate. A limit assembly is provided on the back of the screening box. The limit assembly includes a limit strip on the back of the screening box. The limit strip has a concave cross-section. The surface of each slider is in contact with the surface of the limit strip.
[0009] Preferably, a herringbone frame is fixedly connected to the back of the screening box, a rectangular block is slidably connected inside the herringbone frame, a round rod is fixedly connected to the rectangular block, and the round rod is fixedly connected to the limiting strip.
[0010] Preferably, limiting plates are fixedly connected to the inner surfaces of both sides of the rectangular frame, and the surface of each limiting plate is in contact with the surface of the rectangular block.
[0011] Preferably, the cross-section of each of the support slide rails is U-shaped, and the upper surface of the support slide rail is set as an inclined surface.
[0012] Preferably, a rotating shaft is rotatably connected to the door, and multiple striking strips are fixedly connected to the rotating shaft.
[0013] Preferably, two transparent observation windows are fixedly connected to the door, and the two transparent observation windows are arranged symmetrically.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] Push the rectangular block upwards, then pull the limiting strip outwards to detach the rectangular block from the U-shaped frame. After the limiting strip moves, it will detach from the surfaces of the two sliders. Under the elastic force of the two springs, the two bent rods are located on the outside of the two mounting plates respectively. Then, pull the box door outwards to detach it from the screening box. Then, the two screen plates can be pulled out from their respective support slide rails for more thorough cleaning. This allows for a more thorough cleaning of both the upper and lower screen plates simultaneously, effectively preventing a deterioration in the subsequent screening effect of the grain and facilitating the use of the screening machine.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model.

[0023] Reference Figures 1-4 A grain processing assembly line screening machine includes a frame and a screening box 1 mounted on the frame. A door 5 is provided on one side of the screening box 1, and the door 5 has good sealing when connected to the screening box 1. Multiple support slide rails 12 are fixedly connected to one side surface of the door 5, and two screen plates 11 are arranged between the multiple support slide rails 12. Mounting plates 3 are fixedly connected to both sides of the door 5. Two sliders 7 are mounted on the back of the screening box 1 via two springs 6. A bent rod 4 is fixedly connected to each slider 7. A circular hole for connecting the bent rod 4 is provided on each mounting plate 3. A limit assembly is provided on the back of the screening box 1, including a limit strip 8 on the back of the screening box 1. The limit strip 8 has a U-shaped cross-section, and the surface of each slider 7 is in contact with the surface of the limit strip 8.
[0024] A U-shaped frame 15 is fixedly connected to the back of the screening box 1. A rectangular block 14 is slidably connected inside the U-shaped frame 15. A round rod 13 is fixedly connected to the rectangular block 14. The round rod 13 is fixedly connected to the limiting strip 8. Limiting plates 16 are fixedly connected to the inner surfaces of both sides of the U-shaped frame 15. The surface of each limiting plate 16 is in contact with the surface of the rectangular block 14. The two limiting plates 16 can prevent the rectangular block 14 from detaching from the U-shaped frame 15 at will. The surface of each limiting plate 16 in contact with the rectangular block 14 is relatively rough to prevent the rectangular block 14 from detaching from the U-shaped frame 15. The relative sliding between the rectangular block 14 and the limiting plate 16 can also prevent the rectangular block 14 from moving up and down significantly during the vibration of the screening box 1, thereby preventing the rectangular block 14 from separating from the loop frame 15. The limiting strip 8 will also not separate from the slider 7. When the upper surface of the rectangular block 14 is in contact with the upper inner wall of the loop frame 15, the rectangular block 14 is completely offset from the two limiting plates 16. Then, by pulling the limiting strip 8 outward, the rectangular block 14 can be separated from the loop frame 15. After the limiting strip 8 moves, it will separate from the surface of the two sliders 7.
[0025] Each support slide rail 12 has a concave cross-section, and the upper surface of the support slide rail 12 is set as an inclined surface. When each sieve plate 11 is connected to the concave support slide rail 12, the sealing performance is good. The inclined surface can effectively prevent grain from accumulating on the upper surface of the support slide rail 12. A rotating shaft 10 is rotatably connected to the door 5. Multiple tapping strips 9 are fixedly connected to the rotating shaft 10. The servo motor drives the rotating shaft 10 to rotate in both directions multiple times. During the back-and-forth rotation of the multiple tapping strips 9, the upper and lower sieve plates 11 can be tapped back and forth. The sieve plates 11 vibrate so that the impurities blocking them can fall off. Two transparent observation windows 2 are fixedly connected to the door 5. The two transparent observation windows 2 are symmetrically arranged. Through the transparent observation windows 2, the grain screening situation can be observed more intuitively when the door 5 is not opened.
[0026] In this invention, when the two sieve plates 11 are severely clogged by impurities, the rectangular block 14 is first pushed upwards, causing it to move upwards along the limiting plate 16. When the upper surface of the rectangular block 14 is in contact with the upper inner wall of the loop frame 15, the rectangular block 14 is completely displaced from the two limiting plates 16. Then, the limiting strip 8 is pulled outwards, causing the rectangular block 14 to detach from the loop frame 15. After the limiting strip 8 moves, it will detach from the surface of the two sliders 7. Since each slider 7 is horizontally slidably mounted on the screening box 1, and one end of each spring 6 is fixedly connected to the corresponding slider 7, and the other end is fixedly connected to the screening box 1, under the elastic force of the two springs 6, the two sliders 7 will... The screening box 1 slides relative to each other, and the distance between the two sliders 7 increases. In the initial state, one end of each of the two bent rods 4 is inserted into the corresponding round hole. After each bent rod 4 moves with the slider 7, it will disengage from the corresponding round hole. The two bent rods 4 are located on the outside of the two mounting plates 3 respectively. Then, the box door 5 can be pulled outward to disengage it from the screening box 1. Then, the two screen plates 11 can be pulled out from the support slide rails 12 to facilitate a more thorough cleaning of the screen plates 11. This allows for a more thorough cleaning of both the upper and lower screen plates 11 at the same time, effectively preventing a deterioration in the subsequent screening effect of the grain and facilitating the use of the screening machine.
