Description

Technical Field

[0001] This invention relates to the field of grain machinery technology, specifically to a combined device for preventing grain grading and reducing breakage in shallow circular silos. Background Technology

[0002] In existing technologies, the feed inlet of a grain silo is typically located at the top. During the feeding process, the grain accumulates into a cone shape, and subsequent feed slides from the top to the bottom of the cone. During this sliding process, grain particles undergo grading based on their characteristics; specifically, particles of the same grade are distributed on different circumferences of the cone's projection. Taking rice as an example, smaller particles are distributed at the bottom of the cone, near the silo's sidewalls, while larger, more intact particles are concentrated further away from the sidewalls. This uneven distribution can easily occur during feed collection.

[0003] As described in application number 201921193423.4, the non-powered automatic material distribution and anti-grading device uses a material distribution component fixedly installed at the top of the inner cavity of the silo. After the grain reaches a sufficient weight, the door is pressed open toward the powder chamber, and the material forms a material flow of equal thickness in the distribution trough. The material is then evenly distributed to each chute by the distribution trough with equal width, and then evenly spread into the grain silo through the discharge port on each chute.

[0004] Based on the above data retrieval, it can be seen that existing grain silos lack pre-screening treatment for substandard grains and impurities, resulting in the inability to effectively remove broken grains generated during grain transportation. Furthermore, the feeding assembly is fixedly installed at the top of the silo's inner cavity. Grain silos are typically set high to increase capacity, and when grain is fed into the silo from the top, the height of the silo easily leads to grain breakage. Broken grain is prone to insect infestation and spoilage, affecting the overall effective storage period of the grain in the silo. Therefore, a shallow circular silo grain anti-grading and breakage reduction combined device is proposed. This device can reduce grain breakage during feeding and simultaneously screen out substandard grains, providing a reliable guarantee for the effective storage of grains. Summary of the Invention

[0030] This invention provides a combined device for preventing grain grading and reducing breakage in shallow circular silos. It has the following beneficial effects:

[0031] (1) The present invention, through the coordinated arrangement of the pretreatment box, the drive component and the wire winding and unwinding component, can realize the lifting and lowering adjustment of the cloth component. During the grain entering the silo, the lifting and lowering of the cloth component, in conjunction with the stretchable and foldable material basin integrated component, can realize the lowering height of the grain, thereby reducing the amount of grain breakage.

[0032] (2) The present invention achieves S-shaped feeding of grain by using a bottomless material basin, steel wire rope and angle iron block. This avoids grain breakage and allows adjacent bottomless material basins to be stacked as the material feeding assembly rises and falls, which is convenient for storage. With the setting of the box door opening and closing assembly, the box door can be automatically opened when the material feeding assembly descends, which is convenient for grain to enter the box. After the material feeding assembly rises to the set position, the box door can be automatically closed, which is more convenient to use.

[0033] (3) The present invention, through the combination of screen plate, arc-shaped guide and eccentric shaft, can make the screen plate swing and tilt by squeezing it, so as to screen the broken grain during the grain entering the warehouse. At the same time, the alternating use of two feeding troughs can avoid the grain from clogging the feeding trough. With the addition of arc-shaped trough, filter chamber, filter screen plate, discharge port, soft bag tube and valve flange pipe, the screening of broken grain can also be automatically cleaned, ensuring the continuity of grain entering the warehouse and providing convenient guarantee for grain entering the warehouse.

A synchronous stepped swing gear 504 is also fixedly installed at the front end of the eccentric shaft 503. The synchronous stepped swing gear 504 is rotatably installed on the front side of the second partition 302. The top of the 01 is provided with an arc-shaped groove 5011. A filter screen plate 5012 is fixedly installed on the top of the inner wall of the arc-shaped groove 5011. A filter chamber 5013 is fixedly installed at the bottom of the sieve plate 501. A discharge port 5014 communicating with the filter chamber 5013 is provided at the bottom of the sieve plate 501. A soft bag tube 5015 is fixedly installed on the front of the filter chamber 5013. A valve flange pipe 5016 is connected to the front of the pretreatment box 3. One end of the soft bag tube 5015 passes through the second partition 302 and communicates with the valve flange pipe 5016.

The pretreatment box 3 is fixedly installed between the first partition 301 and the second partition 302. The top of the pretreatment box 3 is provided with a feeding port 303. The tops of the two first arc-shaped plates 5021 are fixedly installed on the top of the inner cavity of the pretreatment box 3, and the two first arc-shaped plates 5021 are respectively arranged on both sides of the feeding port 303. The top of the silo 1 is provided with a feeding port 101. The bottom of the third arc-shaped plate 5023 is fixedly installed on the top of the silo 1, and the two third arc-shaped plates 5023 are respectively arranged on both sides of the feeding port 101. The two sides of the screen plate 501 are in sliding contact with the inner surfaces of the two first arc-shaped plates 5021 and the second arc-shaped plate 5022.

[0064] As a preferred embodiment, to reduce the height from which grain falls, the stretchable and foldable feed trough integrated assembly 8 includes several bottomless feed troughs 801 and four steel wire ropes 802. The several bottomless feed troughs 801 are vertically arranged between the four steel wire ropes 802, and the four steel wire ropes 802 are fixedly connected to the four sides of the bottomless feed troughs 801 respectively. Angle iron blocks 803 are also fixedly installed on the top of the front and rear sides of the inner cavity of the bottomless feed trough 801. In this way, when the grain falls into the bottomless feed trough 801, it rests on the inclined surface of the angle iron block 803. The grain is ejected onto the inner wall of the bottomless grain container 801, then falls onto the inclined surface of the angle iron block 803 in the bottomless grain container 801, and is then ejected onto the inner wall of the bottomless grain container 801, achieving an S-shaped grain entry into the silo. To prevent direct spillage of the grain, the top of the topless grain container 801 is fixedly connected to the top of the inner cavity of the silo 1, and the bottomless grain container 801 is located on the outer periphery of the feed inlet 101. The top ends of the four steel wire ropes 802 are all fixedly connected to the top of the inner cavity of the silo 1. The bottom ends of the four steel wire ropes 802 are all fixedly connected to the top of the fabric assembly 2. Specifically, the fabric assembly 2 includes a positioning block 202, the top of which has an inlet cavity 203. The inlet cavity 203 is used in conjunction with the outer periphery of the bottomless material basin 801. The inside of the positioning block 202 also has a distribution cavity 204. The inlet cavity 203 and the distribution cavity 204 are connected. Six chutes 206 are evenly fixedly installed on the outer periphery of the positioning block 202, and all six chutes 206 are... The six chutes 206 are connected to the distribution chamber 204. Each of the six chutes 206 has two feeding ports 205 at the bottom. One end of each of the six thin steel wires 6031 is fixedly connected to the top of the six chutes 206. Four steel wire ropes 802 are fixedly installed on the top of the positioning block 202. After the grain passes through the bottomless trough 801, it will enter the feeding chamber 203, pass through the distribution chamber 204 and enter the six chutes 206. The grain is then distributed through the feeding ports 205 and the chutes 206.

[0065] To further explain, a material level sensor 201 is also fixedly installed at the bottom of the positioning block 202. The material level sensor 201 is an infrared laser rangefinder used to monitor the distance between the material distribution assembly 2 and the bottom of the inner cavity of the silo 1. When the grain is put into the silo, it monitors the distance between the material distribution assembly 2 and the highest point of the grain, providing a reference and height adjustment basis for the grain to be put into the silo within a safe distance.

[0066] In this embodiment, a low breakage rate can be ensured during the grain entering the warehouse, and the broken grain generated during transportation before the grain is injected into the silo 1 can be screened out, providing a reliable guarantee for the effective storage period of the grain.

[0067] Example 2

[0068] This embodiment, as an improvement on the previous embodiment, provides a shallow circular grain anti-grading and anti-crushing combined device, which further includes a door opening and closing assembly 7. The door opening and closing assembly 7 includes a door 701 and two toothed rollers 702. Two protective plates 703 are fixedly installed on one side of the door 701. Guide rods 704 and first toothed plates 705 are sequentially fixedly installed on one side of each protective plate 703 from top to bottom. Both the guide rods 704 and the first toothed plates 705 penetrate the pretreatment box 3 and extend into its interior. Two toothed rollers 702 are fixedly installed on the left side of the pretreatment box 3's inner cavity. A guide cylinder 706 and two first positioning rods 707 are respectively disposed on the opposite side of the first partition 301 and the second partition 302. The outer periphery of the guide rod 704 slides in contact with the inner surface of the guide cylinder 706. A spring 708 is also disposed inside the guide cylinder 706, and the two ends of the spring 708 respectively contact one end of the guide rod 704 and the left side of the inner cavity of the pretreatment box 3. One end of the first positioning rod 707 passes through the first toothed plate 705 and extends into the interior of the first toothed plate 705.

[0069] Two second positioning rods 709 are fixedly installed on the top of the inner cavity of the pretreatment box 3. A second toothed plate 7010 is sleeved and slidably installed on the outer periphery of the second positioning rods 709. The bottom end of the second toothed plate 7010 penetrates the silo 1 and extends into the interior of the silo 1.

[0070] Two toothed rollers 702 are rotatably installed on the front and rear sides of the pretreatment box 3. The toothed side of the first toothed plate 705 meshes with the top of the toothed roller 702, and the toothed side of the second toothed plate 7010 meshes with the right side of the toothed roller 702. The bottom of the box door 701 slides in contact with the top of the pretreatment box 3. In order to further ensure the stability of the box door 701, two slide rails are also fixed on the top of the pretreatment box 3 to limit the vertical movement of the box door 701.

[0071] A pressing plate 7011 is also fixedly installed on one side of the positioning block 202. The pressing plate 7011 is used in conjunction with the second tooth plate 7010.

[0072] The advantage of Example 2 over Example 1 is that it can automatically leak grain from the feeding port 303 when grain needs to be put into the warehouse, and automatically seal the feeding port 303 after the grain is put into the warehouse.

[0073] The specific steps for using this product include:

[0074] S1. In the initial state, as shown in the attached diagram. Figure 2As shown, during use, the drive motor 401 is started, which drives the drive gear 402 to rotate. The drive gear 402 drives the intermediate gear 403 and the first step swing gear 404 to rotate in opposite directions. The intermediate gear 403 drives the second step swing gear 405 to rotate. At this time, the first step swing gear 404 and the second step swing gear 405 rotate in opposite directions. The first step swing gear 404 and the second step swing gear 405 each drive a small gear 602 to rotate the shaft 601. The shaft 601 starts to release the integrated steel wire 603. Under the gravity traction of the fabric assembly 2, the fabric assembly 2 moves towards the bottom of the inner cavity of the silo 1. During the process, when the material level sensor 201 detects that the distance from the bottom of the inner cavity of the silo 1 is less than 4 meters, the drive motor 401 stops rotating.

[0075] S2. During the descent of the fabric assembly 2, the steel wire rope 802 is driven to cause several bottomless material basins 801 to gradually detach from the bottomless material basins 801 set at the bottom starting from the top.

[0076] When the fabric assembly 2 descends in S1, the fabric assembly 2 drives the extrusion plate 7011 to move downward. During this process, the extrusion plate 7011 gradually disengages from the second toothed plate 7010. During this process, the spring 708 extends and resets, pushing the guide rod 704 to cause the guard plate 703 to move the box door 701 and the first toothed plate 705 until the box door 701 disengages from the feed port 303, allowing the feed port 303 to leak out. During the movement of the first toothed plate 705, the toothed roller 702 rotates, and the toothed roller 702 drives the second toothed plate 7010 to move downward.

[0077] S3. Grain falls from the feed inlet 303 onto the filter screen plate 5012. Broken grains pass through the filter screen plate 5012 into the arc-shaped trough 5011, then through the discharge outlet 5014 into the filter chamber 5013. The grain flows along the bottom of the filter chamber 5013 through the soft bag tube 5015 into the valve flange pipe 5016 and is discharged outside the pretreatment box 3. Grain on the filter screen plate 5012 enters the guide channel 5025 through a discharge trough 5024, then enters the bottomless material basin 801 at the top through the feed inlet 101. Finally, the grain falls into... After passing through the inclined surface of the angle iron block 803 in a bottomless material basin 801, the grain is ejected onto the inner wall of the bottomless material basin 801, and then falls onto the inclined surface of the angle iron block 803 in the bottomless material basin 801. It is then ejected onto the inner wall of the bottomless material basin 801, thus achieving S-shaped grain entry. After the grain passes through the bottomless material basin 801, it enters the feeding chamber 203 of the feeding assembly 2, and then enters the six chutes 206 through the distributing chamber 204. The grain is then scattered into the interior of the silo 1 through the feeding port 205 and the chutes 206.

[0078] S4. When the level sensor 201 detects that the distance between the grain and the bottom of the inner cavity of the silo 1 is less than the preset safety distance (this safety distance can be set by the user), the drive motor 401 is rotated in the reverse direction, causing the rotating shaft 601 to tighten the integrated steel wire 603, which in turn causes the thin steel wire 6031 to drive the cloth assembly 2 to rise a set distance. Then, the rotation of the drive motor 401 is stopped. During this process, as shown in the attached... Figure 11 As shown, the bottomless material tray 801 set at the bottom will first stack with the bottomless material tray 801 set at the next bottom, and then the stacking will repeat as the fabric component 2 rises.

[0079] S5. When the fabric assembly 2 rises to the point where the extrusion plate 7011 contacts the second toothed plate 7010, it indicates that the grain feeding is complete. Continue to control the drive motor 401 to reverse. The extrusion plate 7011 presses the second toothed plate 7010 upward to make it move upward. The second toothed plate 7010 drives the toothed roller 702 to rotate. The toothed roller 702 drives the first toothed plate 705 to move. The first toothed plate 705 drives the guard plate 703 to move the box door 701 and the guide rod 704 until the box door 701 completely blocks the feeding port 303. During the process, the guide rod 704 compresses the spring 708.

[0080] It should be noted that during the rotation of the drive motor 401, the first stepped oscillating gear 404 and the second stepped oscillating gear 405 will rotate synchronously in opposite directions, thereby driving an eccentric shaft 503 to alternately contact the bottom of the screen plate 501, as shown in the attached diagram. Figure 9 Figures b and d show the states of the second-step oscillating gear 405 when it rotates 90° and 270°, respectively. It should be noted that during the feeding process, the screen plate 501 needs to be used alternately in the states shown in Figures b and d. That is, during the feeding process, when the drive motor 401 stops, the screen plate 501 should be in the state shown in Figure b or d. As an optional solution, the intermediate gear 403, the first-step oscillating gear 404 and the second-step oscillating gear 405 have the same shape and size. When the transmission ratio between the intermediate gear 403 and the drive gear 402 is 2:1, as long as the drive motor 401 takes one-eighth of a revolution as one stroke, the intermediate gear 403 can be driven to rotate 90 degrees within one stroke.
