Description

Technical Field

[0001] The invention relates to the field of bulk grain storage, and in particular to an automatic bulk grain warehousing device. Background Art

[0002] my country is a major grain producer and also a major grain storage country. At present, there are four main types of warehouses for grain storage in my country: bungalow warehouses, building warehouses, shallow round warehouses and vertical silos. Building warehouses can store both packaged grain and loose grain. Compared with other warehouse types, they have the advantages of small footprint, flexible granary layout, and flexible division of single granary capacity according to demand. They are suitable for construction in areas with expensive land prices, scarce land resources, and the need to store multiple varieties of grain in separate warehouses.

[0003] However, there are also some problems in the application of building warehouses. The single-layer height can reach 10m, and the grain pile height is 8-9m. For example, a building warehouse usually consists of more than 3 layers of grain storage layers and a conveying equipment layer, i.e. the top layer. When entering the warehouse, when the loose grain falls from the top layer to the bottom layer through the chute, the falling height is high and the height difference with the bottom of the warehouse is large, resulting in a fast speed and great impact when the grain enters the warehouse, causing different degrees of breakage and automatic grading of the grain.

[0004] Grain breakage and automatic grading affect and relate to each other. For example, grain breakage causes uneven grain particles and differences in bulk density, which will inevitably cause automatic grading when entering the warehouse. Therefore, controlling the grain breakage rate can reduce the occurrence of automatic grading when grain enters the warehouse. Grain breakage and automatic grading bring many unfavorable factors to the long-term storage of grain, seriously affecting the safety and quality of stored grain. Therefore, it is necessary to invent a bulk grain automatic warehousing device that can slow down the falling speed of grain, thereby reducing the grain breakage rate and reducing the occurrence of automatic grading when grain enters the warehouse. Summary of the invention

[0005] The object of the present invention is to provide an automatic bulk grain storage device which can reduce the bulk grain storage speed and thus reduce the bulk grain breakage.

[0006] In order to solve the above technical problems, the technical solution of a bulk grain automatic warehousing device in the present invention is as follows: A device for automatically feeding bulk grain into a warehouse comprises an upper transmission wheel and a lower transmission wheel with a rotating axis arranged horizontally, a flexible circulation component is wound around the upper transmission wheel and the lower transmission wheel, a plurality of circulation hoppers are fixed at intervals along the circumferential direction on the flexible circulation component, the hopper opening of the circulation hopper on the left side of the flexible circulation component faces downward, the hopper opening of the circulation hopper on the right side of the flexible circulation component faces upward, a bulk grain feeding hopper is arranged on the upper side of the circulation hopper on the right side of the flexible circulation component, and during the rotation of the circulation hopper with the flexible circulation member, the uppermost circulation hopper on the right side of the flexible circulation member is used to receive the bulk grain discharged from the bulk grain feeding hopper, and the hopper opening of the circulation hopper on the lower side of the lower transmission wheel faces downward and is used to discharge the bulk grain.

[0007] Furthermore, the rotation of the flexible circulation member depends on the transmission wheel motor connected to the upper transmission wheel and the lower transmission wheel, or the rotation of the flexible circulation member depends on the deadweight of the bulk grain in the circulation hopper on the right side of the flexible circulation member.

[0008] Furthermore, the automatic bulk grain warehousing device also includes a left barrel and a right barrel located on the upper side of the lower transmission wheel, and the left barrel cover is arranged on the outer periphery of the flexible circulation component on the left and the circulation hopper on the left side of the flexible circulation component; the right barrel cover is arranged on the outer periphery of the flexible circulation component on the right and the circulation hopper on the right side of the flexible circulation component.

[0009] Furthermore, the automatic bulk grain silo feeding device also includes a laser ranging sensor for detecting the height of the grain pile in the silo.

[0010] Furthermore, a hopper valve core that can move up and down is provided in the bulk grain feed hopper, and the inner wall of the bulk grain feed hopper is a conical structure with a larger upper part and a smaller lower part. The hopper valve core has a valve core mating part that contacts and seals with the inner wall of the bulk grain feed hopper. A control rocker arm is hinged on the left side of the bulk grain feed hopper, and a rocker arm return spring is provided between the control rocker arm and the bulk grain feed hopper. The control rocker arm is connected to the upper end of the hopper valve core by a pull rope. During the rotation of the flexible circulation component, the bottom of the circulation hopper on the upper side of the upper transmission wheel pushes the control rocker arm, and the control rocker arm lifts the hopper valve core by the pull rope, and a bulk grain channel is formed between the hopper valve core and the inner wall of the bulk grain feed hopper. When the circulation hopper on the upper side of the upper transmission wheel passes over the control rocker arm, the hopper valve core moves downward, and the valve core mating part contacts and seals with the inner wall of the bulk grain feed hopper.

[0011] Furthermore, the outer peripheral surface of the hopper valve core on the upper side of the valve core matching part is a conical structure with a small top and a large bottom, and the outer peripheral surface of the hopper valve core on the lower side of the valve core matching part is a conical structure with a large top and a small bottom.

[0012] Furthermore, a vertically arranged valve core column is fixed to the upper end of the hopper valve core, the upper end of the pull rope is connected to the upper end of the valve core column, an elastic plate is fixed to the inner wall of the hopper valve core on the upper side of the valve core column, and a central hole for the pull rope and loose grain to pass through is provided in the center of the elastic plate. When the pull rope moves the hopper valve core upward, the upper end of the valve core column contacts and cooperates with the bottom of the elastic plate to block the central hole. When the hopper valve core moves downward, a space for loose grain to pass through is formed between the valve core column and the elastic plate.

[0013] The beneficial effects of the present invention are as follows: in the present invention, the circulating hopper arranged on the flexible circulating member realizes the operation of bulk grain entering the warehouse as the flexible circulating member rotates, which can reduce the bulk grain entering the warehouse speed compared to the traditional method of completely relying on the free fall of the bulk grain weight. Specifically, multiple circulating hoppers rotate in a cycle with the flexible circulating member, and the direction of the hopper opening of the circulating hopper pair will change when passing through the upper transmission wheel and the lower transmission wheel. In the present invention, when passing through the upper transmission wheel, the hopper opening of the circulating hopper starts to face upward and is used to receive the bulk grain discharged from the bulk grain feeding hopper. When the circulating hopper passes through the lower transmission wheel, the hopper opening of the circulating hopper starts to face downward, thereby discharging the bulk grain in the circulating hopper.

[0015] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. Preferred embodiments of the present invention are provided in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0016] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0017] An embodiment of an automatic bulk grain storage device of the present invention is as follows: Figures 1 to 7 As shown: it includes an upper transmission wheel 2 and a lower transmission wheel 7 whose rotation axis extends in the front-to-back direction. The upper transmission wheel 2 is a driving wheel driven by a transmission wheel motor 10. A flexible circulation component 4 is wound around the upper transmission wheel 2 and the lower transmission wheel 7. That is to say, the upper transmission wheel and the lower transmission wheel are connected through the flexible circulation component 4. The flexible circulation component in this embodiment is a rubber belt (or chain). The lower transmission wheel can move up and down. A tensioning device 8 is connected to the lower transmission wheel. The tensioning device is used to adjust the upper and lower positions of the lower transmission wheel to achieve tensioning of the flexible circulation component.

[0018] The above all belong to the prior art and will not be described in detail here.

[0019] A plurality of circulation hoppers 5 are fixed at intervals along the circumferential direction on the flexible circulation member 4. The circulation hoppers 5 are respectively arranged in various directions of the flexible circulation member. For example, there is a circulation hopper on the right side of the flexible circulation member, there is a circulation hopper on the left side of the flexible circulation member, there is a circulation hopper on the upper side of the flexible circulation member, that is, on the upper side of the upper transmission wheel, and there is a circulation hopper on the lower side of the flexible circulation member, that is, on the lower side of the lower transmission wheel. The circulation hoppers are overturned and reversed at the upper transmission wheel and the lower transmission wheel. In this embodiment, the flexible circulation member is Figure 1 The viewing angle rotates clockwise, the hopper opening of the circulation hopper on the left side of the flexible circulation member faces downward, and the hopper opening of the circulation hopper on the right side of the flexible circulation member faces upward. A bulk grain feed hopper 1 is arranged on the upper side of the circulation hopper on the right side of the flexible circulation member. During the rotation of the circulation hopper with the flexible circulation member 4, the uppermost circulation hopper on the right side of the flexible circulation member is used to receive the bulk grain discharged from the bulk grain feed hopper, and the hopper opening of the circulation hopper on the lower side of the lower transmission wheel faces downward and is used to discharge the bulk grain 11. Item 12 in the figure indicates the hopper opening of the corresponding circulation hopper.

[0020] In this embodiment, the automatic bulk grain warehousing device also includes a left barrel 6 and a right barrel 3 located on the upper side of the lower transmission wheel. The left barrel 6 covers the flexible circulation component on the left side and the periphery of the circulation hopper on the left side of the flexible circulation component; the right barrel 3 covers the flexible circulation component on the right side and the periphery of the circulation hopper on the right side of the flexible circulation component.

[0021] A horizontal conveyor 15 is provided on the upper side of the bulk grain feed hopper, and the horizontal conveyor 15 is used to convey the bulk grain to the bulk grain feed hopper in a horizontal direction. The bulk grain automatic silo device also includes a laser rangefinder sensor for detecting the height of the grain pile in the silo, and according to the height of the grain pile, it can control whether the drive wheel motor is working and whether to distribute grain into the silo.

[0022] In this embodiment, the inner wall of the bulk grain feed hopper 1 is a conical structure with a large upper part and a small lower part. A hopper valve core 20 capable of moving up and down is provided in the bulk grain feed hopper. The hopper valve core 20 has a valve core matching portion 25 that contacts and seals with the inner wall of the bulk grain feed hopper. The valve core matching portion 25 is a conical structure with a large upper part and a small lower part. A control swing arm 18 is hinged on the left side of the bulk grain feed hopper. The hinge axis of the control swing arm 18 extends in the front-to-back direction. A swing arm reset spring 19 is provided between the control swing arm and the bulk grain feed hopper. The swing arm reset spring is a tension spring connected between the control swing arm and the feed hopper.

[0023] The control rocker arm 18 is connected to the upper end of the hopper valve core 20 through a pull rope 17. In this embodiment, a first reversing pulley is provided on the left side of the bulk grain feed hopper, and a second reversing pulley 16 is provided at the central upper end of the bulk grain feed hopper. The space between the second reversing pulley 16 and the inner wall of the bulk grain feed hopper can allow bulk grain to pass from top to bottom. After the pull rope passes through the first reversing pulley and the second reversing pulley and changes direction, one end of the pull rope is connected to the control rocker arm, and the other end is connected to the hopper valve core.

[0024] During the rotation of the flexible circulation component, the bottom of the circulation hopper on the upper side of the upper transmission wheel pushes the control swing rod 18, and the control swing rod lifts the hopper valve core 20 through the pull rope 17, and a loose grain channel is formed between the hopper valve core 20 and the inner wall of the loose grain feed hopper. When the circulation hopper on the upper side of the upper transmission wheel passes over the control swing rod, the hopper valve core moves downward, and the valve core matching part contacts and seals with the inner wall of the loose grain feed hopper. In this embodiment, the outer peripheral surface of the hopper valve core on the upper side of the valve core matching part is a conical structure with a small top and a large bottom, and the outer peripheral surface of the hopper valve core on the lower side of the valve core matching part is a conical structure with a large top and a small bottom. In this way, on the one hand, the grain storage space on the upper side of the valve core matching part can be increased, and on the other hand, the matching area between the valve core matching part and the inner wall of the loose grain feed hopper can be reduced, and the loose grain mixed between the valve core matching part and the inner wall of the loose grain feed hopper can be reduced, so that the discharge port of the loose grain feed hopper can be smoothly closed. In other embodiments of the present invention, the valve core fitting portion may also be a circle of blade-shaped structure, and a wire seal is used between the valve core fitting portion and the inner wall of the bulk grain feed hopper to achieve sealing of the discharge port of the bulk grain feed hopper.

[0025] A vertically arranged valve core column 21 is fixed to the upper end of the hopper valve core, and the upper end of the pull rope 17 is connected to the upper end of the valve core column 21. An elastic plate 22 is fixed to the inner wall of the hopper valve core on the upper side of the valve core column. A central hole 23 for the pull rope and loose grain to pass through is arranged in the center of the elastic plate 22. When the pull rope 17 moves the hopper valve core 20 upward, the upper end of the valve core column contacts and cooperates with the bottom of the elastic plate to block the central hole. When the hopper valve core moves downward, a loose grain passing space 24 is formed between the valve core column 21 and the elastic plate 22. Item 9 in the figure represents a floor slab.

[0026] When in use, the transmission wheel motor drives the flexible circulation component to rotate clockwise. Figure 4 As shown in FIG. 1 , the uppermost circulating hopper on the right side of the flexible circulating member is at the material receiving position, and the circulating hopper 13 on the upper side of the upper driving wheel pushes the control swing rod to swing downward as the flexible circulating member rotates, and the control swing rod raises the height of the hopper valve core through the pull rope, as shown in FIG. Figure 6 As shown, the bulk grain falls into the uppermost circulation hopper on the right side of the flexible circulation component through the gap between the valve core matching part and the inner wall of the bulk grain feed hopper. During the upward movement of the hopper valve core and the valve core column, the upper end of the valve core column pushes the elastic plate to elastically deform upward, the center hole of the elastic plate is blocked, and the bulk grain on the lower side of the elastic plate falls into the corresponding circulation hopper, realizing quantitative feeding of the circulation hopper. After the circulation hopper on the upper side of the upper transmission wheel passes over the control swing arm, the hopper valve core quickly moves downward under the elastic force of the elastic plate and the deadweight of the hopper valve core and the valve core column, and the valve core matching part contacts and matches with the inner wall of the bulk grain feed hopper, the bulk grain feed hopper no longer discharges downward, and the circulation hopper on the upper side of the upper transmission wheel rotates to the material receiving position, and the next material receiving work is started to prevent the bulk grain discharged from the bulk grain feed hopper from falling to other positions due to the space difference between the two adjacent circulation hoppers.

[0027] In the present invention, the rotation speed of the flexible circulation member can be controlled by the transmission wheel motor, thereby controlling the bulk grain entry speed. The bulk grain is no longer free-falling from high altitude to the ground, so the grain breakage rate can be controlled, and the automatic classification phenomenon when the grain enters the warehouse can be reduced. In other embodiments of the present invention, the transmission wheel motor can also be omitted. In this case, the weight of the bulk grain in each circulation hopper on the right side of the flexible circulation member can be relied on to drive the flexible circulation member to rotate clockwise.
