Description

Technical Field

[0001] The invention relates to the technical field of agricultural production, and in particular to a grain transport pipe structure and a transverse grain transport structure. Background Art

[0002] As the saying goes, food is the first necessity of the people. my country is a big country with a population of 1.4 billion. Ensuring an adequate supply of food is particularly important for social stability. Every harvest season, the harvested rice will be stored in the granary in a centralized and unified manner for emergency use. After the harvested rice is loaded into the truck, it will be transported to the granary by road for a period of time. At this time, the rice in the cargo compartment must be transferred to the granary. The traditional practice is to open the cargo compartment door of the truck to pour the rice directly into the granary. For small granaries, this approach is simple and clear, and has good adaptability. However, if the granary space is large and high, this approach will inevitably make the upper space of the granary unable to be fully utilized. At this time, it is usually necessary to fill the upper space of the granary manually. This not only wastes human resources, but also wastes time, causing the progress of grain storage to lag behind. With the continuous improvement of the degree of mechanization of agricultural production, traditional practices are increasingly unable to meet people's actual needs. Faced with the gradual transition from the previous extensive production method dominated by manual operations to the intensive production method dominated by mechanical operations, agricultural production personnel are in a dilemma.

[0003] In the process of using mechanical operations to store grain in warehouses, grain is only entered into the warehouse one by one, which makes it impossible to transport and distribute grain in the warehouse, which may cause grain storage pests and diseases. Summary of the invention

[0004] The invention discloses a grain transport pipe structure and a transverse grain transport structure, aiming to solve the problem of grain storage pests and diseases that may be caused by grain entering a warehouse through only one grain entrance in the prior art, which makes it impossible to transport and distribute grain in the warehouse.

[0006] grain transport support;

[0007] A grain transport pipeline is arranged on the grain transport bracket; a grain transport cavity is formed in the grain transport pipeline, and a grain inlet communicating with the grain transport cavity is arranged on the grain transport pipeline; and,

[0008] The grain pushing mechanism is arranged on the grain transport bracket and extends into the grain transport cavity, and is used for pushing the grain from the grain inlet along the extension direction of the grain transport pipeline to a direction away from the grain inlet.

[0012] A grain pushing mechanism is respectively arranged at both ends of the grain transport pipeline, and each of the grain pushing mechanisms extends into a grain transport cavity and extends to the grain inlet.

[0013] Optionally, the grain pushing mechanism includes a spiral propulsion shaft disposed in the grain transport cavity and extending along the length direction of the grain transport pipe, and a spiral propulsion drive structure connected to the spiral propulsion shaft, and the spiral propulsion drive structure is disposed on the grain transport bracket.

[0014] Optionally, the spiral propulsion shaft includes a propulsion shaft body disposed in the grain transport cavity, and a plurality of propulsion blades protruding in a spiral shape on the circumference of the propulsion shaft body.

[0015] Optionally, the spiral propulsion shaft includes a propulsion shaft body disposed in the grain transport cavity, and a pushing groove spirally opened on the propulsion shaft body.

[0016] Optionally, the spiral pushing drive structure includes a spiral pushing motor arranged on the grain transport bracket, and a spiral pushing reducer connected to the spiral pushing motor, and the spiral pushing reducer is connected to the spiral propulsion shaft.

[0017] Optionally, the grain transport bracket includes a bracket body respectively arranged at both ends of the grain transport pipe, and a pipe fixing ring correspondingly connected to each bracket body, each pipe fixing ring is correspondingly sleeved on one end of the grain transport pipe, and the spiral pushing drive structure is arranged on the bracket body.

[0018] Optionally, the grain transport bracket also includes a connecting rod connecting the bracket body and the pipe fixing ring, a drive structure installation space is formed between the bracket body and the pipe fixing ring, and the spiral push drive structure is located in the drive structure installation space.

[0019] The present invention also provides a transverse grain conveying structure, comprising a grain transport pipe structure and a grain discharge hopper structure arranged at the bottom of a grain transport pipeline of the grain transport pipe structure;

[0020] The grain discharge hopper structure comprises a plurality of grain discharge hopper bodies evenly arranged at the bottom of the grain transport pipeline, and the hopper cavity of each of the grain discharge hopper bodies is connected to the grain transport cavity of the grain transport pipeline.

[0040] As the saying goes, food is the first necessity of the people. my country is a big country with a population of 1.4 billion. Ensuring an adequate supply of food is particularly important for social stability. At the harvest season, the harvested rice will be stored in the granary in a centralized manner for emergency use. Traditional granaries are mainly large flat warehouses, and the storage of grain is basically done by manpower. This not only wastes time, but also places great workload on the workers. In addition, manual labor will make it impossible to evenly distribute the grain in the granary, forming small hills one by one, resulting in low space utilization in the granary. The grain is easily affected by the conical heat flow and becomes moldy and deteriorates, which in turn causes a series of pest and disease problems.

[0041] With the continuous improvement of the mechanization of agricultural production, traditional methods are increasingly unable to meet people's actual needs. Faced with the gradual transition from the previous extensive production method dominated by manual labor to the intensive production method dominated by mechanical operations, agricultural production personnel are in a dilemma.

[0042] In view of this, see Figure 1 The present invention provides a grain distribution robot 4000, which can evenly distribute the grain in the granary 600, adopt mechanized grain distribution operation, and realize the transformation of agricultural production towards intensive production. The grain distribution robot 4000 includes a feeding mechanism 3000 and a grain conveying and distributing device 2000. The feeding mechanism 3000 is arranged outside the granary 600, and is used to convey the grain to the grain conveying and distributing device 2000. The feeding mechanism 3000 includes a feeding rack 400 inclinedly arranged outside the granary 600, a feeding conveyor belt 410 arranged on the feeding rack 400, and a feeding hopper 500 arranged at the upper end of the feeding conveyor belt 410. The feeding hopper 500 is located above the horizontal grain conveyor belt 1100 of the grain conveying and distributing device 2000. The grain is transported to the feeding hopper 500 via the feeding conveyor belt 410 of the feeding rack 400, and is transmitted to the grain conveying and distributing device 2000 by the feeding hopper 500. The grain conveying and distributing device 2000 includes a grain distributing structure 1000, a horizontal grain conveying belt 1100, and a transverse grain distributing structure; the horizontal grain conveying belt 1100 is fixedly arranged on the top of the grain bin 600 and corresponds to the feeding mechanism 3000, and the transverse grain distributing structure 1200 is slidably arranged on the top of the grain bin 600 for distributing grain. This grain distributing robot 4000 can make the grain in the grain bin 600 more evenly distributed, while avoiding the problem of pests and diseases, and can also effectively improve the work efficiency, making the grain transportation and distribution process more controllable.

[0043] As mentioned above, the grain conveying and distributing device includes a grain distributing structure 1000, a horizontal grain conveying belt 1100 and a transverse grain distributing structure 1200. A horizontal grain flow is formed on the horizontal grain conveying belt 1100, and the grain distributing structure 1000 is used to intercept the horizontal grain flow, which is the starting point for subsequent grain storage. Figures 2 to 4 The grain distribution structure 1000 includes a collection bin 100 with a collection cavity 110. The collection cavity 110 in the collection bin 100 collects grains to facilitate the grain distribution operation of the horizontal grain distribution structure. A feed bin 200 having a feed cavity 210 communicating with the collection cavity 110 is provided on the top of the collection bin 100, and a guide plate 300 protruding from the top of the feed bin 200 is provided. A belt installation gap 310 for the horizontal grain conveyor belt 1100 to pass through is formed between the bottom of the guide plate 300 and the top of the collection bin 100. The collection bin 100 is connected to the horizontal grain distribution structure 1200. During operation, the horizontal grain conveyor belt 1100 is passed through the material belt installation gap 310, and the guide plate 300 intercepts the grain on the horizontal grain conveyor belt 1100 and enters the feed bin 200, and reaches the collection bin 100 through the feed cavity 210, and then passes through the collection cavity 110 of the collection bin 100 to be collected into the horizontal grain distribution structure, so as to facilitate the subsequent transportation and distribution process of the grain.

[0044] In order to allow the grain to smoothly enter the collecting bin 100 through the feed bin 200, a feed port 220 communicating with the feed cavity 210 is provided on the side of the feed bin 200, and the feed port 220 corresponds to the side of the horizontal grain conveyor belt 1100. In addition, a guide plate 300 is protrudingly arranged outside the feed port 220, and is used to intercept the grain transported on the horizontal grain conveyor belt 1100 and enter the feed port 220.

[0045] The function of the guide plate 300 is to intercept the grain flow on the horizontal grain conveyor belt 1100. To better realize its function, the guide plate 300 can be set to extend obliquely from the side edge of the feed bin 200 to the conveying start end of the horizontal grain conveyor belt 1100 to achieve a better interception effect. Specifically, during the working process, first, the guide plate 300 intercepts the horizontal grain flow on the horizontal grain conveyor belt 1100, and the grain enters the feed bin 200 through the feed port 220, and transitions from the feed cavity 210 to the collection cavity 110, and finally reaches the collection bin 100. The grain in the collection bin 100 is provided to the transverse grain distribution structure 1200, and the transverse grain distribution structure 1200 transports and distributes the grain in the granary 600.

[0046] It should be noted that only one feed bin 200 can be set on the top of the aggregate bin 100, and then a material guide plate 300 can be set on the feed bin 200 accordingly. However, this approach makes the working efficiency of the grain distribution structure 1000 low, and the impact load acting on the wall of the feed bin 200 is large, which can easily cause structural damage and is not conducive to long-term use.

[0047] In order to improve its working efficiency and enhance the durability of the structure. A feed bin 200 can be set on both sides of the top of the aggregate bin 100, and each feed bin 200 is provided with a guide plate 300. Further, the two feed bins 200 can be symmetrically arranged about the extension line of the horizontal grain conveyor belt 1100, so that a wider range of horizontal grain flow can be intercepted at one time. Alternatively, the two feed bins 200 can be staggered about the extension line of the horizontal grain conveyor belt 1100. In this way, if the workload of the first feed bin 200 is large, a part of the grain can be left for the second feed bin 200 to achieve a reasonable allocation of resources. In addition, setting up two feed bins 200 can also bring convenience to the later maintenance of the equipment. If one of the feed bins 200 works abnormally and needs to be repaired, the feed bin 200 that needs to be repaired can be shut down at this time, and the other feed bin 200 can keep working to maintain the normal operation of the equipment and ensure that the grain warehousing work is uninterrupted.

[0048] Further, see Figure 3 and Figure 4 , the feed ports 220 of the two feed bins 200 can be arranged relatively to each other, and the two guide plates 300 protruding from the outside of the feed ports 220 can also be arranged relatively to each other. The feed bins 200, feed ports 220 and guide plates 300 arranged symmetrically to each other not only give people a sense of beauty visually, but also enable them to better cooperate with each other, and play the role of 1+1>2. At this time, the material belt installation gap 310 is formed between the top of the collection bin 100 and the bottom of the two guide plates 300. In addition, the ends of the two guide plates 300 can be connected to each other to form a whole. On the one hand, this makes the integrity of the structure stronger and resists more external risks. On the other hand, it can also make the interception effect of the guide plates 300 better. It should be further explained that the ends of the two guide plates 300 can be connected to each other as a whole to form a V-shaped plate structure 320.

[0049] It should be noted that, since the intercepted horizontal grain flow finally all converges in the collection bin 100, in order to facilitate the transportation and distribution of the grain in the later stage, a partition plate can be provided in the collection bin 100, and the partition plate separates the collection cavity 110 into the first collection chamber and the second collection chamber. Compared with simply gathering the grain in a large collection cavity 110, the collection bin 100 provided with the partition plate divides the grain into the first collection chamber and the second collection chamber, and the volume of the grain stored therein is relatively small, which is convenient for the transportation and distribution of the grain in the later stage.

[0050] The transportation and distribution of grain is inseparable from the transverse grain distribution structure 1200, which distributes the grain in the collection bin 100 to various places in the granary 600. The transverse grain distribution structure 1200 is slidably arranged on the top of the granary 600, and it includes a distribution pipe structure 700 and a distribution hopper structure 800. For details, see Figure 2 The distribution pipe structure 700 includes a distribution frame 710, a distribution pipe 720 and a spiral grain pushing mechanism 730; the distribution pipe 720 is arranged on the distribution frame 710 and is connected and installed at the discharge port 120 of the grain distribution structure 1000. The discharge port 120 is arranged at the bottom of the collection bin 100, and it guides the grain in the collection bin 100 into the distribution pipe 720. The distribution frame 710 provides structural support for the distribution pipe 720 and the spiral grain pushing mechanism 730 to help them function normally. The spiral grain pushing mechanism 730 is arranged on the distribution frame 710. It should be further explained that a distribution cavity 721 is formed in the distribution pipe 720 to temporarily store grain, and the spiral grain pushing mechanism 730 extends into the distribution cavity 721, which is used to spirally push the grain along the extension direction of the distribution pipe 720 in a direction away from the discharge port 120, so that the grain is transported and distributed in the distribution pipe 720.

[0051] Furthermore, in order to make the material distribution rack 710 more stably fix the material distribution pipe 720, the material distribution rack 710 may include a first support frame body 711a disposed at both ends of the material distribution pipe 720, and a pipe fixing ring 711b correspondingly connected to the first support frame body 711a, and each pipe fixing ring 711b is correspondingly sleeved on one end of the material distribution pipe 720. The material distribution pipe 720 can be fixed to the material distribution rack 710 via the pipe fixing ring 711b, and the connection is stable and not easy to fall off.

[0052] It should be noted that the grain can enter the distribution pipe 720 from the collection bin 100 thanks to the existence of the discharge port 120 arranged at the bottom of the collection bin 100. Without departing from the substantive content of the present invention, there are many ways to set the discharge port 120. For example, the discharge port 120 is opened at one end of the distribution pipe 720, a distribution cavity 721 is formed in the distribution pipe 720, and a spiral grain pushing mechanism 730 is provided at the other end of the distribution pipe 720. The spiral grain pushing mechanism 730 extends into the distribution cavity 721 and extends to the discharge port 120. The advantage of this approach is that only one set of spiral grain pushing mechanism 730 is set, which is convenient for layout and saves costs. However, there is also a disadvantage that when the distribution pipe 720 is long, the spiral grain pushing mechanism 730 is slightly underpowered and cannot achieve a good effect of transporting and distributing grain. To overcome this shortcoming, the following setting method can be adopted: the discharge port 120 is opened in the middle of the distribution pipe 720, and a distribution cavity 721 is formed on both sides of the distribution pipe 720. A spiral grain pushing mechanism 730 is set at each end of the distribution pipe 720, and each spiral grain pushing mechanism 730 extends into a distribution cavity 721 and extends to the discharge port 120. In this way, the discharge port 120 is set in the middle of the distribution pipe 720, and two sets of spiral grain pushing mechanisms 730 are equipped, which can effectively solve the problem of insufficient pushing power when the distribution pipe 720 is long. However, its structure is slightly complicated and the cost is increased. The above two methods can be selected by yourself in the actual production process. For example, when the distribution pipe 720 is short, the first method can be adopted; when the distribution pipe 720 is long, the second method can be selected. It can be compared and selected according to the actual situation to improve economic benefits, so it is not limited here.

[0053] Undoubtedly, the feeding pipe structure 700 is used to transport and distribute grain, and the spiral grain pushing structure plays an irreplaceable role. Figure 5 and Figure 6 The spiral grain pushing mechanism 730 includes a spiral propulsion shaft 731 disposed in the material distributing cavity 721 and extending along the length direction of the material distributing pipe 720, and a spiral propulsion driving structure 732 connected to the spiral propulsion shaft 731, and the spiral propulsion driving structure 732 is disposed on the material distributing frame 710. The spiral propulsion shaft 731 is a pusher for transporting and distributing grain, and the spiral propulsion driving structure 732 provides propulsion power for the spiral propulsion shaft 731. It should be noted that the material distributing frame 710 provides an installation foundation for the entire structure, and the material distributing frame 710 includes a first support frame body 711a and a pipe fixing ring 711b. Further, the material distributing frame 710 may also include a connecting rod 711c connecting the first support frame body 711a and the pipe fixing ring 711b, and a drive structure installation space is formed between the first support frame body 711a and the pipe fixing ring 711b, and the spiral propulsion driving structure 732 is located in the drive structure installation space.

[0054] It should be further explained that the spiral propulsion shaft 731 is a pusher for transporting and distributing grains, and there are many ways to set it without departing from the substantive content of the present invention. For example, the spiral propulsion shaft 731 includes a propulsion shaft body 733 arranged in the material distribution cavity 721, and a plurality of push blades 734 spirally protruding from the circumference of the propulsion shaft body 733. For another example, the spiral propulsion shaft 731 includes a propulsion shaft body 733 arranged in the material distribution cavity 721, and a push groove spirally opened on the propulsion shaft body 733. It should be pointed out that in the former setting, since the push blade 734 is protruding from the circumference of the propulsion shaft body 733, it is easy to break, and the push blade 734 is easy to be bent and broken when encountering a foreign object. Therefore, the latter setting adopts the setting of the push groove, which can not only achieve the effect of transporting and distributing grains, but also effectively avoid the unfavorable situation of bending and breaking.

[0055] Since the spiral push drive structure 732 provides propulsion power for the spiral propulsion shaft 731, it is the power source of the spiral grain push mechanism 730 and can be said to be the heart of the spiral grain push mechanism 730. Figure 5 The screw push driving structure 732 includes a screw push motor 735 disposed on the material distributing frame 710, and a screw push reducer 736 connected to the screw push motor 735, and the screw push reducer 736 is connected to the screw propulsion shaft 731. Since similar drive structures are already relatively mature technologies, they will not be described in detail here.

[0056] It should be further explained that the material distribution pipe structure 700 is used to transport and distribute grain in the granary 600. In the actual working process, if there is too much grain in the material distribution pipe 720, it will cause damage to the material distribution pipe 720 and thus affect the storage of grain in the silo. To solve this problem, a material sensing mechanism 900 can be arranged in the material distribution pipe 720, and the material sensing mechanism 900 can be used to sense the grain capacity in the material distribution pipe 720 in real time to avoid such problems. It should be explained that the material sensing mechanism 900 can be set in many ways. It can be set as a laser sensing structure 910, an infrared sensing structure, and a sonar sensing structure without departing from the substantive content of the present invention. The laser sensing structure 910 used in this embodiment will be described in detail below.

[0057] See also Figures 8 to 10The laser sensing structure 910 includes a laser transmitter 920 disposed on the material distribution frame 710, and a laser receiver 930 rotatably disposed on the inner wall of the material distribution pipe 720, and the laser receiver 930 cooperates with the laser transmitter 920; wherein, when the grain in the material distribution pipe 720 reaches the end of the material distribution pipe 720 and the laser receiver 930 is squeezed out of the end of the material distribution pipe 720, and the laser receiver 930 is aligned with the laser transmitter 920, the laser receiver 930 works normally, and this is the normal working state of the laser sensing structure 910 (i.e., Fig. 9 ), indicating that the grain flow in the distribution pipe 720 is within a normal range and the distribution pipe 720 is in good operating condition.

[0058] Specifically, the material distribution pipe 720 includes a horizontal pipe body 723 disposed on the material distribution frame 710, and a pipe elbow 724 disposed at the end of the pipe body, and the opening direction of the pipe elbow 724 is vertically upward; the laser receiver 930 includes a material baffle 931 hinged at the end of the pipe body and located in the inner cavity of the pipe elbow 724, and a laser receiving plate 932 protruding from the material baffle 931, and the laser receiving plate 932 cooperates with the laser transmitter 920920. Further, the material distribution pipe 720 is in the initial state (i.e., Figure 8 ), there is no grain in the pipe. At this time, the material baffle 931 is blocked at the end of the pipe body, and the laser receiving plate 932 is located in the inner cavity of the pipe elbow 724 and is misaligned with the laser transmitter 920. With the operation of the material distribution pipe structure 700, grain gradually flows into the distribution pipe 720. When the flow rate in the pipe is in a normal state (i.e., Fig. 9 state), that is, when the distribution pipe 720 is operating in a normal state, the material baffle 931 rotates toward the outlet of the pipe elbow 724 under the squeeze of the grain material in the pipe body, so that the laser receiving plate 932 protrudes out of the outlet of the pipe elbow 724 and corresponds to the laser emitter 920. The laser emitted by the laser emitter 920 shines on the laser receiving plate 932, so that the staff knows that the internal operation of the grain transport pipe is good and in a normal working state; however, when the grain feed rate is too large, there is too much grain in the distribution pipe 720. If it runs for a long time, it will cause damage to the distribution pipe structure 700 and affect the storage of grain into the warehouse. The staff needs to make timely adjustments. Therefore, in an abnormal working state (that is, Fig.10 ), the material baffle 931 rotates to the outside of the pipe elbow 724 under the pressure of the food material in the pipe body, and the laser receiving plate 932 protrudes from the outside of the pipe elbow 724 and is misaligned with the laser emitter 920. At this time, the laser emitted by the laser emitter 920 cannot be normally received by the laser receiving plate 932, so that the staff can promptly discover the abnormal operation state of the material distribution pipe 720 and make timely adjustments to prevent structural damage and delays in production progress.

[0059] Further, see Figure 8 , the pipe elbow 724 can be set as a circular arc elbow, and the material baffle 931 can be set as a fan-shaped baffle matched with the circular arc elbow. Furthermore, in order to avoid excessive accumulation of grain in the pipe body and a greater obstruction to the transportation and distribution of grain, the height value of the top opening of the pipe elbow 724 can be set to be less than or equal to the radius value of the pipe body, so that an overflow port can be formed at the end of the material distribution pipe 720. When the grain flow inside the pipe is too large, the excess grain can be discharged in time through the overflow port to avoid structural damage.

[0060] As mentioned above, the transverse grain distribution structure 1200 is slidably arranged on the top of the granary 600, and it includes a distribution pipe structure 700 and a distribution hopper structure 800. After the distribution pipe structure 700 has completed the transportation and distribution of grain along the distribution pipe 720, at this time, the distribution hopper body 810 of the distribution hopper structure 800 connected to the distribution pipe 720 is filled with grain, and the funnel mouth 811 is opened, so that the distribution pipe structure 700 slides on the top of the granary 600, and the grain can be transported and distributed in the granary 600. However, in the actual working process, the grain flow condition in the distribution pipe 720 will change, and at this time, the grain in the distribution pipe 720 needs to be unloaded according to the actual situation.

[0061] To this end, the material distribution hopper structure 800 may include a plurality of material distribution hopper bodies 810 and a flow regulating mechanism 820. The flow regulating mechanism 820 may adjust the discharge flow of the material distribution hopper body 810 according to actual conditions to solve this problem. Figure 7 , multiple distribution hopper bodies 810 are respectively arranged at the bottom of the distribution pipe 720, and are used to discharge the grain in the distribution pipe 720 from multiple positions at the bottom of the distribution pipe 720; the flow regulating mechanism 820 includes an adjusting drive structure 821 arranged on the distribution frame 710, and a flow regulating plate 822 connected to the adjusting drive structure 821, the flow regulating plate 822 is arranged at the funnel opening 811 at the bottom of multiple grain discharge hopper bodies, and a plurality of adjusting holes 823 are opened on the flow regulating plate 822, each adjusting hole 823 corresponds to a funnel opening 811, and the adjusting drive structure 821 is used to drive the flow regulating plate 822 to move so that the adjusting hole 823 is misaligned or aligned with the funnel opening 811. It should be noted that when the adjustment hole 823 and the funnel mouth 811 are misaligned or aligned, the overlapping area is constantly changing. If the overlapping area between the two is larger, it means that the material hopper structure 800 unloads grain faster; conversely, if the overlapping area between the two is smaller, the grain output speed is slower.

[0062] Further, see Figure 5 and Figure 6, the adjustment drive structure 821 includes a linear drive structure 821a provided on the material distribution frame 710, and a drive connecting rod 821b connected to the linear drive structure 821a, and the drive connecting rod 821b is connected to the flow regulating plate 822. It should be noted that the linear drive structure 821a can be set as a linear drive motor. Specifically, the linear drive structure 821a includes a servo drive motor provided on the support structure, and a linear transmission structure connected to the servo drive motor, and the linear transmission structure is connected to the drive connecting rod 821b. In addition, the linear transmission structure can be set as a screw nut transmission structure or a gear rack transmission structure.

[0063] It should be noted that the role of the regulating drive structure 821 is to provide power for the flow regulating plate 822 to adjust the opening size of the funnel mouth 811. Therefore, without departing from the essential content of the present invention, any mechanical component that can provide power can be used, such as: cylinder or hydraulic cylinder, etc.

[0064] In order to make the regulating function of the flow regulating plate 822 more excellent and reduce the working pressure of the regulating driving structure 821, in the present technical solution, the flow regulating plate 822 can be set as a thin plate, and, accordingly, the regulating driving structure 821 includes a connecting block 821c arranged at the bottom of one end of the flow regulating plate, and the driving connecting rod 821b is connected to the connecting block 821c.

[0065] In order to obtain a more comprehensive adjustment effect, please refer to Figure 7 The material distribution hopper structure 800 may also include a hopper bottom plate 814 arranged at the bottom of the multiple material distribution hopper bodies 810, and the hopper bottom plate 814 is connected to the material distribution frame 710; a plurality of discharge holes 815 are opened at the bottom of the hopper bottom plate 814, and the plurality of discharge holes 815 are directly opposite to the funnel openings 811 of the multiple material distribution hopper bodies 810, and correspond to the plurality of adjustment holes 823 on the flow adjustment plate 822.

[0066] Specifically, each material distribution hopper body 810 includes a hopper fixing plate 812 fixed on the material distribution pipe 720 and a hopper body 813 connected to the hopper fixing plate 812 . A hopper bottom plate 814 is disposed at the bottom of the plurality of hopper bodies 813 .

[0067] It should be noted that the material distribution frame 710 mainly plays the role of a supporting structure in the present invention. The material distribution frame 710 may include a first support frame 711 and a second support frame 712 respectively arranged at both ends of the material distribution pipe 720; and in order to make the horizontal grain distribution structure 1200 slide on the top of the granary 600, the material distribution frame 710 may also include a support rail 713 respectively arranged on the first support frame 711 and the second support frame 712, and a track motor arranged on the first support frame 711 or the second support frame 712. The two support rails 713 correspond to the guide rails on the top of the granary 600 one by one and slide in cooperation.

[0068] In addition, in order to enable the material sensing mechanism 900 to work in coordination with the material distribution hopper structure 800, to achieve control of the flow regulating mechanism 820 according to the working state of the laser sensing structure 910, and to flexibly adjust the grain flow in the material distribution pipe 720, the transverse grain distribution structure 1200 may also include a controller electrically connected to both the laser transmitter 920 and the laser receiver 930, and the controller is also electrically connected to the adjustment drive structure 821 of the flow regulating mechanism 820. Specifically, during the working process, if the laser sensing structure 910 senses that the grain flow in the pipe is too large and may threaten the normal operation of the mechanism, it will feedback the working condition information in the pipe to the controller. The controller receives the information that the working condition in the pipe is not good and the material distribution pipe 720 is in an abnormal working state, then the controller controls the adjustment drive structure 821 to drive the flow regulating plate 822 to increase the overlap area of ​​the adjustment hole 823 and the funnel mouth 811, so as to achieve the purpose of quickly unloading the grain in the pipe, so as to adjust the bad working condition in the pipe and adjust the material distribution pipe 720 to a normal working state as soon as possible.

[0069] In the present invention, the working process of the preferred embodiment is as follows: the grain distribution robot 4000 includes a feeding mechanism 3000 and a grain conveying and distributing device, wherein the grain conveying and distributing device includes a horizontal grain conveyor belt 1100, a grain distributing structure 1000 and a transverse grain distributing structure 1200; the feeding mechanism 3000 transports the grain located outside the grain silo 600 to the horizontal grain conveyor belt 1100 on the top of the grain silo 600. A horizontal grain flow is formed on the horizontal grain conveyor belt 1100, and the grain distributing structure 1000 intercepts the flow to allow the grain to enter the transverse grain distributing structure 1200. The transverse grain distributing structure 1200 is slidably arranged on the top of the granary 600. The transverse grain distributing structure 1200 can spirally propel the grain to be pre-transported and distributed along the first direction of the granary 600. Then, the transverse grain distributing structure 1200 that has pre-transported and distributed the grain can move along the top of the granary 600 along the second direction interlaced with the first direction. At this time, the funnel 811 at the bottom of the transverse grain distributing structure 1200 is opened, and the grain is output to the granary 600. Compared with the previous manual operation method, on the one hand, it can save labor costs, and on the other hand, the grain output in this way is more evenly distributed in the granary 600, which can significantly improve the utilization rate of the granary 600 and effectively prevent pests and diseases during the grain storage process. The present invention greatly improves the mechanization degree of agricultural production, changing the previous extensive production method dominated by manual operation to an intensive production method dominated by mechanical operation.
