Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural machinery, in particular to a slope grassland planting bag filling and applying device. BACKGROUND

[0002] Slope grassland is a special form of topography and vegetation cover, usually located on the slopes or inclined land. Compared with flat land, the vegetation cover of slope grassland is often more sparse, and its ecosystem is more fragile. In recent years, due to the influence of climate change, frequent extreme weather events, and human activities such as overgrazing and unreasonable land use, the degradation of slope grassland has become increasingly serious. The main manifestations are soil erosion, soil structure destruction, physical property deterioration, significant decline in soil fertility, and reduction of grassland species diversity. These problems not only seriously affect the ecological function and service value of slope grassland, such as water conservation, soil conservation, and biodiversity maintenance, but also have a serious negative impact on the surrounding livestock industry which relies on these grassland resources.

[0003] Traditional slope grassland restoration methods mainly include direct grass seed supplementation and fertilization measures, but practice shows that the effect of these methods is limited and difficult to meet actual needs. In order to improve the restoration effect, a new method has been adopted in recent years - planting bags combined with artificial grass seed supplementation and fertilization. This method can effectively improve soil conditions and promote plant growth, thereby accelerating the restoration process of slope grassland. However, when implementing this restoration strategy, the application method mainly relies on manual operation with heavy equipment such as cranes, which not only increases the operation cost, but also has a high safety risk. In addition, for some areas with poor transportation conditions or particularly rugged terrain, the existing application method is difficult to apply, limiting the widespread application and promotion of this method.

[0004] Therefore, developing a new type of slope grassland restoration and application technology and equipment that is safe, economical and efficient, and suitable for various complex terrain conditions, has become a problem to be solved. SUMMARY

[0005] The purpose of the present application is to provide a slope grassland planting bag filling and applying device to solve the technical problem of safety risk in manual operation with heavy equipment such as cranes in the prior art.

[0057] The following is in conjunction with the appendix Figures 1-5 To further describe this application in detail, embodiments of this application disclose a device for filling and distributing vegetation bags on slope grasslands.

[0058] Referring to Figure 1 and Figure 2 The present application provides a slope grassland planting bag filling and applying device, which comprises a carriage, a filling mechanism, a feeding mechanism, a conveying mechanism and a sealing mechanism.

[0059] The carriage can be used in cooperation with a transport vehicle and is installed on the transport vehicle during use. The top and rear section of the carriage are both provided with openings that are in communication with the carriage. A partition is fixedly installed on the carriage, and the partition divides the inner cavity of the carriage into a containing cavity at the front end and a conveying cavity at the rear section. The containing cavity is used to contain sand soil for repairing slope grassland. The filling mechanism is installed in the containing cavity and is used to convey the sand soil in the containing cavity to the conveying cavity. The feeding mechanism is installed at the front end of the filling mechanism. The conveying mechanism is installed on the carriage and is located below the feeding mechanism. The sealing mechanism is installed at the front end of the conveying mechanism.

[0060] Referring to Figure 1 and Figure 2 The filling mechanism 200 comprises a feeding pipe 210, a spiral feeding shaft 220, a feeding motor 230, a feeding hopper 250, a conveying pipe 260 and an elbow 240.

[0061] The feeding pipe 210 is obliquely arranged and fixedly installed on the carriage 100, with one end abutting against the bottom surface of the containing cavity 120 and the other end extending toward the partition 110. This oblique design ensures that the sand soil can be smoothly extracted from the bottom of the containing cavity 120 and conveyed by gravity assistance. The elbow 240 is fixedly connected to the end of the feeding pipe 210 close to the partition 110 and is arranged in an L shape, with one end fixedly connected to the feeding pipe 210 and the other end outputting sand soil toward the bottom surface of the containing cavity 120. Such a structure not only improves the efficiency of material transmission but also reduces the residual amount of material in the pipeline, ensuring the cleanliness and consistency of each operation.

[0062] The feeding hopper 250 is fixedly connected to the partition 110 and is located in the containing cavity 120 below the elbow 240, ensuring that the sand soil can accurately fall into it. The spiral feeding shaft 220 is rotationally arranged in the feeding pipe 210, with the axial direction parallel to the length extension direction of the feeding pipe 210. This configuration enables the spiral feeding shaft 220 to form an effective pushing force inside the feeding pipe 210, efficiently extracting sand soil from the containing cavity 120.

[0063] The feeding motor 230 is fixedly installed on the partition 110, with its output shaft penetrating the connection point between the elbow 240 and the feeding pipe 210 and being fixedly connected to the spiral feeding shaft 220 coaxially. The rotation of the motor drives the spiral feeding shaft 220 to rotate, thereby realizing the extraction and conveying of sand soil. This design simplifies the mechanical structure, improves the stability and reliability of the system.

[0064] The material conveying pipe 260 is also inclined, with one end fixedly connected to the feeding hopper 250 through the partition plate 110 and in communication with the feeding hopper 250. The other end of the material conveying pipe 260 extends away from the partition plate 110 by the conveying cavity 130, and is lower than the end connected to the feeding hopper 250, so that the sand flows along the material conveying pipe 260 by gravity. This design not only improves the efficiency of material conveying, but also reduces the need for additional power and energy consumption. In addition, the inclined arrangement helps to prevent material blockage, improving the overall performance and service life of the device.

[0065] Referring to Figure 2 and Figure 3 The feeding mechanism 300 includes a bracket 310 and two motorized rollers 320.

[0066] The bracket 310 is sleeved on the material conveying pipe 260 and fixedly connected to the inner wall of the carriage 100 through two connecting plates 330 on both sides. This design not only provides stable support, but also enables the entire device to withstand greater working loads. The design of the bracket 310 ensures the stability of the material conveying pipe 260 during the filling process, avoiding position deviation caused by vibration or external forces, thereby ensuring the accuracy and reliability of material conveying.

[0067] The two motorized rollers 320 are symmetrically arranged around the material conveying pipe 260, with the axial direction of the motorized rollers 320 perpendicular to the lengthwise extension direction of the material conveying pipe 260. The rotation directions of the two motorized rollers 320 are oppositely arranged, which ensures that the grow bag moves smoothly and uniformly during the filling process. The opposite rotation of the motorized rollers 320 drives the grow bag using friction, allowing it to continuously move outward, thereby achieving efficient and continuous sand filling.

[0068] During use, the grow bag that needs to be filled with sand is sleeved on the material conveying pipe 260 between the partition plate 110 and the bracket 310, and one end of the grow bag is pulled out between the motorized rollers 320 and the material conveying pipe 260 and beyond the material conveying pipe 260. When the material conveying pipe 260 conveys sand outward, the sand is just delivered into the interior of the grow bag. At this time, the motorized rollers 320 are started, driving the grow bag to move outward along the material conveying pipe 260 using friction, ensuring continuous filling of sand into the grow bag. This design significantly improves the filling efficiency, reduces manual intervention, and reduces labor intensity.

[0069] The grow bag is a long and continuous cylindrical bag with both ends open. This structure facilitates quick installation and disassembly, while ensuring smooth flow of materials during the filling process.

[0070] Referring to Figure 3 and Figure 4As shown, the conveying mechanism 400 comprises a support frame 410, an extension frame 420, a conveying motor 460, a conveying gear 470 and a conveying belt assembly 450.

[0071] The support frame 410 is rotatably mounted at the tail end of the carriage 100. This rotatable design allows the support frame 410 to adjust the angle according to the actual needs, thereby improving the flexibility and adaptability of the device. The conveying motor 460 is fixedly connected to the bottom of the tail end of the carriage 100, and its output shaft is connected with the conveying gear 470 through the carriage 100. The conveying gear 470 is fixedly connected to the output shaft of the conveying motor 460 and is arranged in the conveying cavity 130. The tail end of the support frame 410 is provided with an annular gear groove, and the conveying gear 470 is clamped in the annular gear groove. In this way, the rotation of the conveying motor 460 can accurately drive the support frame 410 to rotate, ensuring the stability and reliability of the operation.

[0072] The extension frame 420 is slidingly arranged on the support frame 410 and slides along the length direction of the support frame 410. The support frame 410 is provided with a first electric cylinder 430, the cylinder body of which is fixedly mounted on the support frame 410, and the piston rod is fixedly connected to the extension frame 420, so as to realize the telescopic function of the extension frame 420. This telescopic mechanism not only enhances the expansion capability of the device, but also can flexibly adjust the conveying distance according to needs.

[0073] The conveying belt assembly 450 comprises a driving motor 453, a driving shaft 451, a driven shaft 454 and a conveying belt 452. The driving shaft 451 is rotatably arranged at one end of the support frame 410 away from the extension frame 420, and the driving motor 453 is fixedly connected to the support frame 410 and connected with the driving shaft 451, for driving the driving shaft 451 to rotate. The driven shaft 454 is rotatably arranged at one end of the extension frame 420 away from the support frame 410. The conveying belt 452 is mounted on the driving shaft 451 and the driven shaft 454, and the driving motor 453 drives the driving shaft 451 to rotate to drive the conveying belt 452 to move back and forth. When the extension frame 420 is fully extended, the conveying belt 452 is fully unfolded; and when the extension frame 420 is retracted, the conveying belt 452 is bent. This design not only ensures the stability and continuity of material transportation, but also effectively reduces the space occupation.

[0074] The top of the support frame 410 is also rotatably provided with an auxiliary roller 440, which plays an important role in use. The material conveying pipe 260 is located above the support frame 410, and the planting bag filled with sand is dropped from above the support frame 410 to the conveying belt 452, and is transported by the movement of the conveying belt 452. When the planting bag is transported by the support frame 410 to the conveying belt 452, it will contact the auxiliary roller 440 on the top of the support frame 410. The rotation of the auxiliary roller 440 helps the planting bag to smoothly fall onto the conveying belt 452, avoiding the problem of being stuck on the support frame 410, making the material more smooth when entering the conveying belt 452, and further improving the transportation efficiency and stability.

[0075] Referring to Figure 3 and Figure 5 As shown, the sealing mechanism 500 includes a sealing seat 510, a second electric cylinder 520, and a push plate 530.

[0076] The sealing seat 510 is fixedly connected to the front end of the extension frame 420, and a containing groove 540 for containing the U-shaped sealing rod is formed in the sealing seat 510. The side of the containing groove 540 is arranged in a stepped manner, specifically, one end of the containing groove 540 is open at the top and close to the extension frame 420, and the other end of the containing groove 540 is open at the bottom and away from the extension frame 420. The middle plane position of the containing groove 540 is designed in an inverted U shape, and is arranged inclined downward from one end close to the extension frame 420 to the other end. This design makes the sealing rod can be easily put into the containing groove 540 from the top opening. Through this structure, not only is it convenient for the operator to place the sealing rod, but also ensures that the sealing rod can smoothly slide to the bottom opening under the action of gravity, improving the work efficiency and operation convenience.

[0077] The sealing seat 510 also has a ligature opening 550 in communication with the containing groove 540, and the ligature opening 550 is located above the bottom opening of the containing groove 540. The push plate 530 is slidably arranged in the ligature opening 550, and the second electric cylinder 520 is fixedly installed in the ligature opening 550, and the piston rod thereof is connected to the push plate 530 for pushing the push plate 530 to slide. This design makes the sealing rod can be accurately controlled in force and speed by the electric cylinder when it is pushed into the slope grass surface, thereby ensuring the stability and reliability of the sealing effect.

[0078] In actual use, first, the sealing rod is put into the accommodating groove 540, and the sealing rod slides along the inclined bottom surface to the bottom opening, and the two ends of the U-shaped sealing rod naturally abut against the slope grass surface. The vegetation bag passes through the middle of the sealing rod, so that when the second electric cylinder 520 pushes the push plate 530, the sealing rod will press and ligate the cylindrical vegetation bag, and divide it into small sections. This design not only achieves high sealing effect, but also effectively prevents soil or sand from leaking from the vegetation bag. At the same time, since the sealing rod is in close contact with the slope grass surface, the reliability and stability of the sealing are further enhanced.

[0079] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
