Description

Technical Field

[0001] The invention belongs to the technical field of grain storage equipment, and in particular relates to a shallow circular silo grain feeder. Background Art

[0002] Grain reserves are often necessary to regulate the national grain supply and demand, stabilize the grain market, and respond to major natural disasters or other emergencies. However, during grain storage, especially as it enters shallow silos, automatic grading often occurs. For example, when storing soybeans, fine impurities and broken soybean dregs easily accumulate below the grain inlet. This area has extremely poor air permeability and thermal conductivity, seriously hindering the application and effectiveness of advanced grain storage technologies such as ventilation and cooling, fumigation, and nitrogen storage. This results in poor grain quality, high bacterial loads, active respiration, and numerous insect eggs. This easily causes condensation, heat, and the spread of pests, seriously compromising soybean storage safety. Furthermore, because the shallow silo's sloping grain inlet is high, over 20 meters above the ground, the soybeans are affected by gravity during their fall, resulting in a rapid drop. This increases the number of broken grains during entry and affects the stability of the stored grain. Summary of the Invention

[0003] In view of this, the object of the present invention is to provide a shallow silo grain feeder to solve the problem of automatic grading and grain breakage that is very easy to occur during the shallow silo grain feeding process in the prior art.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the grain distributor for shallow silo of the present invention is:

[0005] A grain distributor for a shallow silo, comprising:

[0006] Frame: used to support the top of the shallow silo;

[0007] Feeding barrel: fixed on the frame;

[0008] Feeding cylinder: It is set below the feeding cylinder and rotates relative to the frame;

[0009] Support plate: fixed at the lower part of the frame, with a through hole for the cloth tube to pass through on the support plate, and an annular groove on the side of the through hole facing the cloth tube, and an annular ridge on the cloth tube, which is supported in the annular groove;

[0010] Driving device: fixedly arranged relative to the frame, the driving device is connected to the distributing drum to rotate the distributing drum;

[0011] The first discharging support cylinder is arranged at the lower part of the distributing cylinder;

[0012] The second discharging support tube is arranged at the lower part of the distributing drum. The second discharging support tube is located below the first discharging support tube. The first discharging support tube and the second discharging support tube are arranged alternately in the circumferential direction of the distributing drum. The distance between the discharging port of the second discharging support tube and the axis of the distributing drum is greater than the distance between the discharging port of the first discharging support tube and the axis of the distributing drum.

[0013] Discharge adjustment mechanism: It is arranged in the distributing cylinder. The discharge adjustment mechanism includes a first working position and a second working position. When the discharge adjustment mechanism is located in the first working position, the grain in the distributing cylinder is discharged from the first discharging branch cylinder; when the discharge adjustment mechanism is located in the second working position, the grain in the distributing cylinder is discharged from the second discharging branch cylinder.

[0014] Beneficial effect: A shallow silo feeding grain distributor of the present invention can rotate under the action of a driving device when grain enters the feeding drum from the feeding drum, and the feeding drum includes a first discharging support drum and a second discharging support drum. Since the discharge port of the first discharging support drum and the discharge port of the second discharging support drum are at different distances from the axis of the feeding drum, when the feeding drum rotates, the grain discharged from the first discharging support drum is circular in the shallow silo, and the grain discharged from the discharge port of the second discharging support drum is circular in the shallow silo, and the diameters of the two circles are different, thereby achieving the purpose of distributing grain in the shallow silo; the first discharging support drum and the second discharging support drum can be adjusted to discharge grain through the setting of the discharging adjustment mechanism, so that grain distribution can be adjusted when the shallow silo feeds grain, avoiding grain grading when feeding grain and affecting grain storage.

[0015] Furthermore, the discharge adjustment mechanism includes a first telescopic hydraulic cylinder arranged at the bottom of the material distributing cylinder, a guide cylinder elastically supported on the top of the first telescopic hydraulic cylinder, the guide cylinder and the inner wall of the material distributing cylinder are slidingly matched, the guide cylinder includes a cylindrical cylinder wall and a conical cylinder bottom, and the cylindrical cylinder wall is provided with a first through hole and a second through hole, the first through hole and the second through hole are staggered in the circumferential direction of the guide cylinder, when the discharge adjustment mechanism is in the first working position, the first through hole corresponds to the first discharge support cylinder, and when the discharge adjustment mechanism is in the second working position, the second through hole corresponds to the second discharge support cylinder.

[0016] Beneficial effects: The discharge adjustment mechanism has a simple structure, and can choose to discharge grain from the first discharge support cylinder or the second discharge support cylinder by changing the working position of the discharge adjustment mechanism, thereby realizing the distribution of grain when feeding into the shallow circular silo.

[0017] Furthermore, a support plate is fixed on the top of the first telescopic hydraulic cylinder, a vertically extending support column is fixed on the support plate, a spring is fixed between the support plate and the conical cylinder bottom, and the spring is passed through the support column.

[0018] Beneficial effect: When the grain feeding speed is high, the grain will produce a large downward impact force on the bottom of the cylinder. At this time, the bottom of the cylinder will compress the spring so that the through hole is opposite to the discharge support cylinder in the up and down directions. The opening of the discharge support cylinder corresponding to the through hole will be completely open, and a large amount of grain will be discharged quickly from the discharge support cylinder. When the grain feeding speed is low, the grain will produce a downward impact on the bottom of the cylinder. At this time, the spring is compressed less, the through hole corresponds to the discharge support cylinder in the up and down directions, and the opening of the discharge support cylinder corresponding to the through hole is partially blocked by the guide cylinder, and the speed at which grain is discharged from the discharge support cylinder is reduced.

[0019] Furthermore, the first discharging support cylinder and the second discharging support cylinder are arranged at 180 degrees at the lower part of the distribution cylinder.

[0020] Beneficial effects: the positioning and installation of the first discharging support cylinder and the second discharging support cylinder are more convenient, and the installation of the first through hole and the second through hole on the guide cylinder is more convenient.

[0021] A gear ring is fixed on the outer wall surface of the material distributing cylinder, and the driving device is a driving motor. The output shaft of the driving motor is provided with a gear meshing with the gear ring for transmission.

[0022] Beneficial effect: the gear is driven to rotate by the driving motor, and the gear is meshed with the gear ring for transmission, thereby realizing the rotation of the fabric drum, and the transmission structure is simpler to set.

[0023] The feeding barrel includes an upper barrel section and a lower barrel section with a flared portion at the upper part, an upper connecting flange is provided at the lower part of the upper barrel section, and an upper connecting flange is provided at the upper part of the lower barrel section. The upper connecting flange includes a front connecting plate and a rear connecting plate provided on the front and rear sides of the upper barrel section; the lower connecting flange includes a lower concave cavity and a front connecting wall and a rear connecting wall provided on the front and rear sides of the lower concave cavity, the front connecting wall is detachably connected to the front connecting plate, and the rear connecting wall is detachably connected to the rear connecting plate, and filter plates are provided on the left and right guides in the lower concave cavity.

[0024] Beneficial effect: The setting of the filter plate can filter impurities in the grain.

[0025] Furthermore, guide strips are provided on the front and rear sides of the filter plate, the front connecting wall is provided with a front guide groove adapted to guide the front guide strip, and the rear connecting wall is provided with a rear guide groove adapted to guide the rear guide strip.

[0026] Beneficial effect: The setting of the guide structure makes the filter plate smoother in the left and right movement process, and the setting of the guide structure also realizes the support of the filter plate.

[0027] The filter plate includes two left and right circular through holes, and filter nets are arranged in the circular through holes.

[0028] Beneficial effect: the filter plate is provided with two filter screens, which can realize that when one filter screen is cleaned, the other filter screen is working, thereby not delaying the filtering of the grain.

[0029] Furthermore, a left rotating shaft and a right rotating shaft are respectively provided on the left and right sides of the filter screen, a rotating motor is provided on the filter plate, the rotating motor is transmission-connected to the left rotating shaft of the filter screen, and a retractable stopping structure is provided on the front and rear sides of the bottom of the filter screen.

[0031] A second telescopic hydraulic cylinder is fixed on the right side of the frame, and the right side of the filter plate is fixedly connected to the telescopic hydraulic cylinder.

DETAILED DESCRIPTION

[0038] The following is a further detailed description of a shallow silo grain distributor according to the present invention in conjunction with the accompanying drawings and specific embodiments:

[0039] like Figure 1As shown, a shallow silo grain feeder of the present invention includes a frame 1 supported on the top of the shallow silo, a feed cylinder fixed on the frame 1, and a feed cylinder 4 provided below the feed cylinder. The diameter of the feed cylinder 4 is approximately larger than the diameter of the feed cylinder, and the upper portion of the feed cylinder 4 overlaps the lower portion of the feed cylinder in the vertical direction. The feed cylinder 4 is rotatably arranged relative to the frame 1. Specifically, a support plate 5 is fixedly provided at the lower portion of the frame 1. The support plate 5 has a through hole corresponding to the position of the feed cylinder 4 for the feed cylinder 4 to pass through. The side of the through hole facing the feed cylinder 4 has an annular groove. The feed cylinder 4 is provided with an annular ridge 6, which is supported in the annular groove. A driving device is fixedly provided on the frame 1, and the driving device is connected to the fabric drum 4 for transmission to rotate the fabric drum 4. Specifically, the driving device is a first driving motor, and a ring gear 7 is fixed to the outer wall surface of the fabric drum 4. A gear meshing with the ring gear 7 is provided on the output shaft of the first driving motor. When the first driving motor rotates, the gear is driven to rotate, and the gear meshes with the ring gear 7 for transmission, thereby driving the fabric drum 4 to rotate through the first driving motor.

[0040] A first discharge branch 8 and a second discharge branch 9 are provided below the distributing drum 4. The second discharge branch 9 is located below the first discharge branch 8. The first and second discharge branches 8 and 9 are arranged alternately in the circumferential direction of the distributing drum 4. In this embodiment, the first and second discharge branches 8 and 9 are arranged at a 180-degree angle below the distributing drum 4. The distance between the discharge opening of the second discharge branch 9 and the axis of the distributing drum 4 is greater than the distance between the discharge opening of the first discharge branch 8 and the axis of the distributing drum 4.

[0041] A discharge adjustment mechanism is provided at the lower portion of the distributing drum 4. The discharge adjustment mechanism includes a first working position and a second working position. When the discharge adjustment mechanism is in the first working position, the grain in the distributing drum 4 is discharged from the first discharge support drum 8; when the discharge adjustment mechanism is in the second working position, the grain in the distributing drum 4 is discharged from the second discharge support drum 9. Specifically, the discharge adjustment mechanism includes a first telescopic hydraulic cylinder 14 provided at the bottom of the distributing drum 4, a guide cylinder elastically supported at the top of the first telescopic hydraulic cylinder 14, and the guide cylinder slidingly cooperating with the inner wall of the distributing drum 4. Specifically, an inwardly protruding guide bar 27 is provided on the inner wall of the distributing drum 4, and a slide groove (not shown in the figure) adapted to the sliding guidance of the guide bar 27 is provided on the outer wall of the guide cylinder. The provision of the guide bar 27 and the slide groove can prevent the guide cylinder from rotating inside the distributing drum 4.

[0042] The guide cylinder includes a cylindrical cylinder wall 10 and a conical cylinder bottom 11. A first through hole 12 and a second through hole 13 are opened on the cylindrical cylinder wall 10. The first through hole 12 and the second through hole 13 are staggered in the circumferential direction of the guide cylinder. In this embodiment, the first through hole 12 and the second through hole 13 are arranged 180 degrees in the circumferential direction of the guide cylinder. When the discharge adjustment mechanism is in the first working position, the first through hole 12 corresponds to the first discharge support cylinder 8, and the bottom of the first through hole 12 is located above the bottom of the communication port between the first discharge support cylinder 8 and the distribution cylinder 4, and the top of the first through hole 12 is located above the top of the communication port between the first discharge support cylinder 8 and the distribution cylinder 4; when the discharge adjustment mechanism is in the second working position, the second through hole 13 corresponds to the second discharge support cylinder 9, and the bottom of the second through hole 13 is located above the bottom of the communication port between the second discharge support cylinder 9 and the distribution cylinder 4, and the top of the second through hole 13 is located above the top of the communication port between the second discharge support cylinder 9 and the distribution cylinder 4.

[0043] A support plate 15 is fixed to the top of the first telescopic hydraulic cylinder 14, and a vertically extending support column 22 is fixed on the support plate 15. A spring 16 is fixed between the support plate 15 and the conical barrel bottom 11, and the spring 16 is passed through the support column 22. When the grain feeding speed is high, the grain produces a large downward impact force on the barrel bottom. At this time, the barrel bottom will compress the spring 16 so that the through hole is directly opposite the discharge branch barrel in the up and down directions. The opening corresponding to the discharge branch barrel and the through hole will be completely open, and a large amount of grain will be discharged quickly from the discharge branch barrel. When the grain feeding speed is low, the downward impact of the grain on the barrel bottom, at this time, the spring 16 is compressed less, the through hole corresponds to the discharge branch barrel in the up and down directions, and the opening corresponding to the discharge branch barrel and the through hole is partially blocked by the guide barrel, and the grain discharge speed from the discharge branch barrel is reduced.

[0044] The feed barrel includes an upper barrel section 2 with a flared upper portion and a lower barrel section 3. The lower barrel section 3 is a straight barrel. An upper connecting flange 17 is provided at the lower portion of the upper barrel section 2, and a lower connecting flange 18 is provided at the upper portion of the lower barrel section 3. The upper connecting flange 17 includes a front connecting plate 23 and a rear connecting plate 24 arranged on the front and rear sides of the upper barrel section 2. The lower connecting flange 18 includes a lower concave cavity and a front connecting wall 25 and a rear connecting wall 26 arranged on the front and rear sides of the lower concave cavity. The front connecting wall 25 is detachably connected to the front connecting plate 23, and the rear connecting wall 26 is detachably connected to the rear connecting plate 24. A filter plate 20 is provided on the left and right guides in the lower concave cavity. Guide bars 27 are provided on the front and rear sides of the filter plate 20. The front connecting wall 25 is provided with a front guide groove that adapts to the guidance of the front guide bar 27, and the rear connecting wall 26 is provided with a rear guide groove that adapts to the guidance of the rear guide bar 27.

[0045] The filter plate 20 includes two circular through holes on the left and right sides, and a filter mesh 21 is provided in the circular through holes. That is, the filter plate 20 is provided with two filtering positions in the left and right directions. A second telescopic hydraulic cylinder 19 is fixed to the right side of the frame 1, and the right side of the filter plate 20 is fixedly connected to the telescopic hydraulic cylinder. By extending and retracting the second telescopic hydraulic cylinder 19, the filter plate 20 can be moved in the left and right directions, thereby realizing the transformation of the two filtering positions of the filter plate 20.

[0046] In this embodiment, the two filter screens 21 on the filter plate 20 can be flipped separately. Specifically, a left rotating shaft and a right rotating shaft are respectively provided on the left and right sides of the filter screen 21. A rotating motor 29 is provided on the filter plate 20, and the rotating motor 29 is transmission-connected to the left rotating shaft of the filter screen 21. A retractable stopping structure 28 is provided on the front and rear sides of the bottom of the filter screen 21. The stopping structure 28 is a telescopic cylinder fixed to the bottom of the filter screen 21. When the telescopic cylinder is extended, the filter screen 21 is stopped in the front and rear directions. At this time, the filter screen 21 is stably arranged relative to the filter plate 20. The filter screen 21 can be used to filter the grain passing through the feeding drum 4. When the telescopic cylinder is retracted, the telescopic cylinder will not stop the filter screen 21 at the bottom of the filter screen 21. At this time, the rotating motor 29 works and can drive the filter screen 21 to rotate in the circular through hole, thereby removing the filtered impurities on the filter screen 21.

[0047] During use, grain enters the distributing drum 4 from the feeding drum, and the distributing drum 4 rotates under the action of the driving device. The distributing drum 4 includes a first discharging branch drum 8 and a second discharging branch drum 9. Since the discharge port of the first discharging branch drum 8 and the discharge port of the second discharging branch drum 9 are at different distances from the axis of the distributing drum 4, when the distributing drum 4 rotates, the grain discharged from the first discharging branch drum 8 is circular in the shallow circular silo, and the grain discharged from the discharge port of the second discharging branch drum 9 is circular in the shallow circular silo, and the diameters of the two circles are different, thereby achieving the purpose of distributing grain in the shallow circular silo; the setting of the discharging adjustment mechanism can adjust the first discharging branch drum 8 and the second discharging branch drum 9 to discharge grain, thereby adjusting the grain distribution when the shallow circular silo is fed, avoiding grain grading when feeding grain, and ensuring the safety of grain storage.

[0048] In the above embodiment, the discharge adjustment mechanism includes a first telescopic hydraulic cylinder arranged at the bottom of the feeding cylinder 4, and a guide cylinder elastically supported on the top of the first telescopic hydraulic cylinder; in other embodiments, the guide cylinder can also be fixed on the upper part of the first telescopic hydraulic cylinder.
