Description

Technical Field

[0001] This utility model relates to the field of crop-livestock recycling technology, and in particular to a manure return device. Background Technology

[0002] In the manure return process of crop-livestock cycle, the final step is to transport the processed and decomposed organic manure to the crop fields that need fertilization, mix the decomposed organic manure with a certain proportion of chemical fertilizers, chemically supplement or adjust the composition of the decomposed organic manure (such as supplementing N, P and / or K elements), and then apply the compounded fertilizer to the field.

[0003] An essential step in the above process is to mix the well-rotted organic manure with chemical fertilizer using a mixing device. For this purpose, the transport vehicle needs to transport the well-rotted organic manure, chemical fertilizer, mixing device, fertilizer transfer vehicle, and fertilization equipment to the fertilization site. Then, all the above equipment is unloaded from the transport vehicle, and the batching, mixing, and fertilization operations are carried out according to the process.

[0004] Since most fertilization sites lack the facilities to run industrial cables or provide large-scale lifting or hoisting equipment, the above work is basically carried out manually or with the help of simple machinery. In this case, not only is a large amount of manpower consumed, but the mixing equipment also needs to be miniaturized. This makes the most critical mixing process too inefficient, and the operation process is close to the traditional manual agricultural operation without machinery. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model proposes a manure returning device that can adapt to the conditions of the fertilization site and can carry out relatively efficient fertilizer batching, mixing and feeding operations without relying on professional lifting or hoisting equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A manure return device includes: Transport vehicles are used to transport well-rotted organic manure storage and feeding components, mixing equipment, and chemical fertilizers to the fertilization site. A well-rotted organic manure storage and feeding assembly is used to supply well-rotted organic manure to mixing equipment without unloading the truck. A mixing device is used to mix well-rotted organic manure and chemical fertilizer without unloading the vehicle. The mixing device has an operating trolley and a mixing working part. The mixing working part has a mixing bin and a downward-facing discharge port. The operating trolley is configured to switch the mixing unit between a transport state and a working state. In the transport state, the mixing unit is positioned inside the load-bearing section of the transport vehicle. In the working state, the mixing bin of the mixing unit is moved to the outside of the load-bearing section of the transport vehicle, so that the discharge port of the mixing bin extends beyond the edge of the load-bearing section of the transport vehicle.

[0007] In the above-described manure return device, preferably, the well-rotted organic manure storage and feeding assembly includes a support frame and a storage bin, wherein the storage bin is suspended on the support frame and a manual unloading valve is connected to the lower part of the storage bin.

[0008] In the manure return device described above, preferably, the operating trolley has wheels distributed on both sides of the mixing bin.

[0009] In the above-described manure returning device, preferably, the transport vehicle is equipped with a counterweight steel plate, the support frame is fixed on the counterweight steel plate, and the mixing equipment is also mounted on the counterweight steel plate.

[0010] In the manure returning device described above, preferably, the counterweight steel plate is provided with a track to guide the traveling wheels or has a guide groove to guide the traveling wheels.

[0011] In the above-described manure return device, preferably, the operating trolley is provided with a first locking structure and the counterweight steel plate is provided with a second locking structure. In the working state, the first locking structure and the second locking structure can cooperate to lock the operating trolley.

[0012] In the manure returning device described above, preferably, a guide plate mounting frame is installed on the storage silo, and the guide plate is detachably mounted on the guide plate mounting frame.

[0013] In the manure returning device described above, preferably, a long strip adjustment groove is provided on the side plate on the side where the guide plate is connected to the guide plate mounting frame.

[0014] In the above-described manure return device, preferably, the mixing equipment is located at the rear end of the load-bearing section of the transport vehicle.

[0015] The manure return device described above preferably also includes a fertilizer transfer vehicle for receiving and transferring the fertilizer released from the unloading port of the mixing silo.

[0016] The beneficial effects of this utility model are: This invention addresses the current situation where, during manure return to the field, fertilization operations lack the resources for running industrial cables, providing large-scale lifting or hoisting equipment, and where the processes of batching, mixing, and fertilization are labor-intensive and inefficient, particularly in the critical mixing stage. It provides a manure return device integrating a well-rotted organic manure storage and supply component and a mixing device on a transport vehicle. The mixing device can mix well-rotted organic manure and chemical fertilizers without unloading the vehicle, and the well-rotted organic manure storage and supply component can supply the well-rotted organic manure to the mixing device without unloading the vehicle. The material mixing equipment has a discharge port that extends beyond the edge of the transport vehicle's load-bearing section, allowing for convenient direct feeding of material into the fertilizer transfer vehicle's hopper. This working mode eliminates the need to move the entire mixing equipment off the transport vehicle, nor does it require significant changes to the equipment's working posture or expansion of its conveying function. The decomposed organic manure storage and feeding component can store and transport large quantities of decomposed organic manure and unload it manually. The entire system is highly suitable for efficient manure return operations in large-scale integrated farming enterprises, resulting in significant industrial benefits. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1 Reference Figure 1-6 This embodiment of a manure return device includes: The transport vehicle 10 is used to transport the well-rotted organic manure storage and feeding assembly 20, the mixing equipment 30, and the chemical fertilizer 40 to the fertilization site.

[0026] The purpose of this embodiment is: 1. The mixing equipment 30 can mix well-rotted organic manure and chemical fertilizer 40 without unloading the truck; 2. The decomposed organic manure storage and feeding component 20 can supply decomposed organic manure to the mixing equipment 30 without unloading the truck.

[0027] First, the composted organic manure storage and supply component 20 is introduced. As a first improvement in the transportation, storage and supply of composted organic manure, the composted organic manure storage and supply component 20 provided in this embodiment is used to supply composted organic manure to the mixing equipment 30 without unloading. Specifically, the composted organic manure storage and supply component 20 includes a support frame 21 and a storage bin 22. The support frame 21 is mounted on the transport vehicle 10.

[0028] In this embodiment, the load-bearing part of the transport vehicle 10 is provided with a counterweight steel plate 11. The load-bearing part of the transport vehicle 10 can be a cargo platform of a flatbed truck or a carriage with railings and side panels, depending on the type of transport vehicle 10 used. The support frame 21 is fixed on the counterweight steel plate 11. The thickness of the counterweight steel plate 11 is more than 10mm, and it has sufficient weight and strength to provide stable support for the composted organic manure storage and feeding assembly 20.

[0029] Through the above robust design, such as Figure 3As shown, the storage bin 22 in this embodiment can be suspended on the support frame 21. The storage bin 22 can be placed on the support frame 21 in any way. It can be fixed by welding, fixed by disassembly, or placed as a whole in the placement groove of the crossbeam of the support frame 21 by gravity. The storage bin 22 can be open or have a cover. It can also be equipped with a hook for easy hoisting in the workshop.

[0030] from Figure 1-4 As can be seen, in this embodiment, the overall height of the composted organic manure storage and supply component 20 exceeds the roof height of the transport vehicle 10. As long as the transport size and load limits are not exceeded, the volume capacity of the storage bin 22 can be appropriately increased to store and transport a large amount of composted organic manure, which is very suitable for the efficient operation of manure return to the field in large-scale planting and breeding cycle enterprises.

[0031] As a preferred option in this embodiment, the lower part of the storage silo 22 is connected to a manual discharge valve 23, so that the material can be discharged at the fertilization site without any external power.

[0032] Next, we will introduce the mixing equipment 30. As mentioned earlier, the primary consideration in this embodiment is to enable the mixing equipment 30 to mix the well-rotted organic manure and chemical fertilizer 40 without unloading the truck.

[0033] See Figure 1-5 The mixing equipment 30 described in this embodiment has an operating trolley 31 and a mixing working part 32, and the mixing equipment 30 is also set on the counterweight steel plate 11 mentioned above.

[0034] Specifically, in this embodiment, since the composted organic manure storage and feeding component 20 is located closer to the tail end of the carrying part of the transport vehicle 10, in order to form a cooperation, the mixing device 30 is located at the tail end of the carrying part of the transport vehicle 10.

[0035] The mixing unit 32 has a mixing bin 321, which has a downward-facing discharge port. In order to enable the mixing equipment 30 to mix the decomposed organic manure and chemical fertilizer 40 without unloading, the solution in this embodiment is to configure the operating trolley 31 to switch the mixing unit 32 between a transport state and a working state.

[0036] Specifically, such as Figure 1 and Figure 3 As shown, in the transportation state (referring to transportation in the transport vehicle 10), the mixing unit 32 can be positioned entirely inside the load-bearing part of the transport vehicle 10.

[0037] like Figure 2 and Figure 4As shown, in the working state (referring to the operation at the fertilization site), the mixing bin 321 of the mixing work unit 32 can be moved to the outside of the bearing part of the transport vehicle 10, so that the discharge port of the mixing bin 321 extends out of the edge of the bearing part of the transport vehicle 10.

[0038] like Figure 6 As shown, the hopper of the fertilizer transfer vehicle 50, which is used to receive and transfer fertilizer released from the discharge port of the mixing bin 321, is open upwards, so that the discharge port of the mixing bin 321 of the mixing equipment 30 extends out of the edge of the carrying part of the transport vehicle 10. This allows for very convenient direct feeding of fertilizer into the hopper of the fertilizer transfer vehicle 50. This working mode does not require moving the mixing equipment 30 out of the transport vehicle 10 as a whole, nor does it require significantly changing the working posture of the mixing equipment 30 or increasing the size of the material conveying function part of the mixing equipment 30, which has very good industrial benefits.

[0039] In order to achieve the functions of the designed operating trolley 31, such as Figure 3-5 As shown, the operating trolley 31 has traveling wheels 33 distributed on both sides of the mixing bin 321, and preferably a track is provided on the counterweight steel plate 11 to guide the traveling wheels 33 or a guide groove is provided on the counterweight steel plate 11 to guide the traveling wheels 33. A pusher 34 is provided at the operated end of the operating trolley 31 to facilitate manual operation.

[0040] In this embodiment, from the attached Figure 1-6 As can be seen, the operating trolley 31 has three rows of wheels 33. One row of wheels 33 is located on the right side of the mixing bin 321 and can extend out of the edge of the load-bearing part of the transport vehicle 10 together with the mixing bin 321 during the operation of the mixing equipment 30. This row of wheels can have one or two. If it is one, it only needs to be installed in the center of the bottom plate of the operating trolley 31. If it is two, they are arranged on both sides of the bottom plate of the operating trolley 31. The other two rows of wheels 33 are located on the left side of the mixing bin 321. These two rows of wheels 33 are the main balance support of the mixing equipment 30. There are two in each row, arranged on both sides of the bottom plate of the operating trolley 31.

[0041] Although the stability of the entire mixing equipment 30 on the transport vehicle 10 can be ensured by the size and weight distribution of the components on the operating trolley 31 when the mixing bin 321 extends beyond the edge of the load-bearing part of the transport vehicle 10, for safety reasons, this embodiment still provides a first locking structure 35 on the operating trolley 31 and a second locking structure 12 on the counterweight steel plate 11. In the working state, after the operating trolley 31 moves to the position where the mixing bin 321 extends beyond the edge of the load-bearing part of the transport vehicle 10 and is in place, the first locking structure 35 on the operating trolley 31 will be in the position of the second locking structure 12 on the counterweight steel plate 11, and the first locking structure 35 and the second locking structure 12 can cooperate to lock the operating trolley 31.

[0042] For example, the first locking structure 35 is a screw or bolt, which is set in the middle position near the edge of the operating trolley 31, and the second locking structure 12 is a fixed platform with a threaded groove, which is set on the path that the first locking structure 35 will take when the operating trolley 31 moves to the right.

[0043] Obviously, the threaded locking structure in the above example is just an example. Any mechanical locking structure that can reliably fix the operating trolley 31 is applicable in this embodiment.

[0044] In addition to the anti-rollover locking structure mentioned above, one or more of the traveling wheels 33 of the operating trolley 31 can also improve the stability of the operating trolley 31 when it is stopped by self-locking.

[0045] The following describes how the well-rotted organic manure storage and feeding component 20 feeds material into the mixing hopper 321 of the mixing equipment 30, such as... Figure 2 and Figure 4 As shown, a guide plate mounting bracket 24 is installed on the storage bin 22. The guide plate 25 is detachably mounted on the guide plate mounting bracket 24. That is, the guide plate 25 is an accessory that can be installed on the guide plate mounting bracket 24 on the storage bin 22 by means of mounting pins or threaded mounting parts when the work starts.

[0046] In order to allow for a certain degree of adjustment of the position of the end of the guide plate 25 extending to the feed inlet of the mixing bin 321, such as... Figure 4 As shown, a long strip adjustment groove 26 is provided on the side plate on the side where the guide plate 25 is connected to the guide plate mounting bracket 24. The aforementioned mounting pin or threaded mounting part can cooperate with the long strip adjustment groove 26 to temporarily lock the position of the guide plate 25 or adjust the angle and position after loosening.

[0047] According to the component construction description of this embodiment, when the transport vehicle 10 arrives at the fertilization site, apart from the fertilizer transfer vehicle 50 and the fertilization device (any fertilization device in the prior art), the other components do not need to be unloaded. Before operation, it is only necessary to push the operating trolley 31 to move the mixing bin 321 of the mixing work unit 32 to the outside of the carrying part of the transport vehicle 10, so that the discharge port of the mixing bin 321 extends out of the edge of the carrying part of the transport vehicle 10 and is in place. Then, the guide plate 25 is installed and adjusted on the guide plate mounting frame 24, and the manual discharge valve 23 is manually operated to release material into the mixing bin 321 of the mixing work unit 32. The inner wall of the mixing bin 321 has volume scales. By observing the scales, the amount of decomposed organic manure released into the mixing bin 321 can be controlled, which is better than relying entirely on the experience of agronomists.

[0048] The amount of chemical fertilizer 40 used is relatively small. The attached figure of this embodiment shows the bagged chemical fertilizer 40. An appropriate amount of chemical fertilizer 40 can be manually scooped into the mixing bin 321 with the decomposed organic manure for mixing. The volume ratio of the two is flexibly controlled by the agronomist according to the purpose of fertilization, different crop types, etc.

[0049] After the well-rotted organic manure and chemical fertilizer 40 are properly mixed, the mixing unit 32 can be started to mix the materials. During this process, the mixing hopper 321 can be either open or closed, depending on the amount of material to be mixed and the operating speed of the mixing element used.

[0050] It should be noted that, according to the concept of this utility model, it is not important what kind of mixing working parts the mixing working part 32 adopts, as long as the discharge port of its mixing bin 321 can extend out of the edge of the bearing part of the transport vehicle 10 and can discharge material into the hopper of the fertilizer transfer vehicle 50 through the discharge port after the mixing is completed.

[0051] Example 2 This embodiment further designs the structure of the mixing unit 32 based on embodiment 1. As mentioned above, the structure of the mixing unit 32 is diverse, and this embodiment is only a preferred option rather than the only solution.

[0052] like Figure 5 As shown, the mixing unit 32 in this embodiment includes a mixing rod 322 located inside the mixing bin 321, and a drive assembly 323 and a transmission assembly 324 that provide power to the mixing rod 322. In this embodiment, the drive assembly 323 is selected as a motor, and the transmission assembly 324 is selected as a sprocket and a chain. Again, as an example, the mixing rod 322 is arranged horizontally inside the mixing bin 321. One side of the rotating shaft extends out of the mixing bin 321 and is driven to rotate by the motor through the transmission of the sprocket and the chain. The other side is mounted on the wall of the mixing bin 321 through a bearing.

[0053] In this embodiment, to facilitate the arrangement of the mixing rod 322, the upper part of the mixing bin 321 is a cube, and the lower four sides taper downwards to form a conical transition, all the way to the discharge port.

[0054] However, the shape of the mixing hopper 321 can also be other common shapes, such as a simple cube, cuboid, cylinder, or a combination of different shapes or a combination of the same shape but different sizes, as long as it is convenient to arrange the mixing components inside and to discharge materials through the downward discharge port.

[0055] exist Figure 5 One significant advantage of the mixing unit 32 shown is that both the drive assembly 323 and the transmission assembly 324 are located on the operating trolley 31 and on the left side of the mixing bin 321. This places the weight on the side that does not extend beyond the edge of the load-bearing part of the transport vehicle 10, which helps improve the stability of the entire mixing equipment 30. In this embodiment, the mixing equipment 30 operates through an independent power supply 36, which is also located on the operating trolley 31 and on the left side of the mixing bin 321. This also places the weight on the side that does not extend beyond the edge of the load-bearing part of the transport vehicle 10, further improving the stability of the entire mixing equipment 30.

[0056] See appendix for further details. Figure 5 In the mixing unit 32 listed in this embodiment, the discharge port of the mixing silo 321 uses a discharge gate 325 for discharge. The discharge gate 325 can adopt any structure in the prior art, such as a downward opening type or a side-sliding opening type. The discharge gate 325 is preferably locked or opened by a manual gate locking member 326. An elastic rubber ring can be used to improve the sealing effect between the discharge port and the discharge gate 325. Although this is just a traditional manual gate valve structure, it can reduce the introduction of electrical components, which is very friendly to outdoor fertilization operation sites like the one described in this application.

[0057] Similarly, the discharge assembly used at the discharge port of the mixing silo 321 can also be other discharge valves in the prior art, as long as they can be locked or opened.

[0058] Example 3 The difference between this embodiment and embodiment 1 is that the fertilizer transfer vehicle 50 is not used, and the discharge port of the mixing silo 321 directly discharges the material into the hopper (not shown in the figure) of the fertilizer application device.

[0059] Example 4 The difference between this embodiment and embodiment 1 is that the mixing device 30 is not located at the rear end of the bearing section near the transport vehicle 10, but is located on one side of the bearing section near the transport vehicle 10. The other components are matched in the same way as in embodiment 1, which can also ensure that the discharge port of the mixing bin 321 can extend out of the edge of the bearing section.

[0060] Example 5 The difference between this embodiment and embodiment 1 is that the first locking structure 35 is changed to a limiting groove located in the middle of the operating trolley 31 near the side, and the second locking structure 12 is changed to a limiting rod that can rotate or move on the counterweight steel plate 11. It is set on the path that the first locking structure 35 will pass through when the operating trolley 31 moves to the right. The cooperation between the limiting groove and the limiting rod is a common structure and will not be shown in the figure.

[0061] Example 6 The difference between this embodiment and embodiment 2 is that there is no independent power supply 36, and the mixing equipment 30 operates directly through the vehicle power supply.

[0062] Example 7 The difference between this embodiment and embodiment 2 is that a mixing unit with a vertical stirring rod is used. The mixing equipment with a vertical stirring rod and a downward discharge port is a common mixing equipment in the prior art and will not be shown in the figure.

[0063] Example 8 The difference between this embodiment and embodiment 2 is that the unloading assembly used at the unloading port of the mixing silo 321 is changed to an electrically controlled valve.

[0064] Example 9 The difference between this embodiment and embodiment 1 is that the mixing silo 321 is equipped with a weight sensor, which controls the amount of decomposed organic manure released into the mixing silo 321 by recognizing the weight, while the chemical fertilizer 40 can be weighed using weighing instruments (electronic scale, balance, etc.).

[0065] Example 10 The difference between this embodiment and embodiment 1 is that the guide plate 25 is replaced by a guide hose, one end of which is fitted onto the outlet of the manual unloading valve 23, and the other end extends to the inlet of the mixing silo 321.

[0066] Example 11 The difference between this embodiment and embodiment 1 is that a separate counterweight steel plate 11 is no longer used. Instead, a support frame 21 is directly installed on the carrying platform of the transport vehicle 10, and the mixing equipment 30 is arranged there.

[0067] Example 12 The difference between this embodiment and embodiment 2 is that the transmission component 324 is selected as a pulley and a belt.

[0068] The above description is only a preferred embodiment of the present utility model. Any equivalent substitutions or modifications made by those skilled in the art based on the technical solution disclosed in the present utility model within the scope of the present utility model should be included within the protection scope of the present utility model.
