Description

Technical Field

[0001] This invention relates to the field of straw fermentation technology, specifically to an agricultural straw substrate fermentation device. Background Technology

[0002] For a long time, the indiscriminate dumping and burning of straw have persisted despite repeated bans. This not only results in a serious waste of biomass resources but also generates large amounts of smoke and harmful gases, causing a series of environmental and safety problems such as air pollution and fire hazards, which violates the concept of green and sustainable agricultural development. At the same time, the long-term and excessive use of chemical fertilizers in modern agriculture easily leads to soil compaction, decreased organic matter content, and soil fertility decline, resulting in a continuously rising market demand for green and ecological organic fertilizers. Converting agricultural straw into commercial organic fertilizer through microbial aerobic fermentation can achieve the reduction, harmlessness, and resource utilization of straw waste, making up for the shortage of organic matter in arable land. It can also build an agricultural circular industrial chain of "straw—organic fertilizer—farmland," combining ecological, social, and economic benefits, and has now become the mainstream technological direction in the field of comprehensive utilization of agricultural waste.

[0003] In the process of straw fermentation, the straw raw material needs to be pre-treated by crushing it to 2-3 cm before composting. During composting, the treated straw needs to be evenly spread, maintaining a certain height and width (0.6-1m) to meet the composting requirements. However, currently, the straw cannot be spread evenly during composting, resulting in inconsistent straw pile heights, which in turn affects the composting effect of the same batch of straw. Therefore, this application is filed to ensure that the compost pile height remains consistent during the composting process. Summary of the Invention

[0004] The purpose of this invention is to provide an agricultural straw substrate fermentation device that solves the problem of inconsistent compost height during the composting process.

[0005] The objective of this invention can be achieved through the following technical solutions: An agricultural straw substrate fermentation device includes a composting trough and a turning mechanism disposed on the composting trough and moving along its length. The turning mechanism includes a sliding plate, an X-axis moving assembly disposed between the sliding plate and the composting trough, and a Y-axis moving assembly disposed inside the sliding plate. The Y-axis moving assembly includes a lead screw rotatably connected inside the sliding plate, and a moving block that can move along the Y-axis is meshed on the lead screw. A limiting groove is formed inside the sliding plate, and the moving block moves inside the limiting groove. A telescopic assembly is fixedly installed at the lower end of the moving block, and a soil turning assembly is fixedly installed at one end of the telescopic assembly.

[0006] As a further embodiment of the present invention: an auxiliary component is provided on the rear side of the moving block, the auxiliary component includes a moving frame fixedly connected to the rear side of the moving block, a connecting shaft is rotatably connected between the moving frame and the moving block, and a connecting gear is sleeved on the connecting shaft, a connecting toothed plate that meshes with the connecting gear is fixedly installed inside the limiting groove, and a baffle is provided at the lower end of the moving frame, the baffle can cover the straw turned up by the turning component.

[0007] As a further embodiment of the present invention: the connecting axis extends outward to the interior of the movable frame and is connected to the bevel gear set, and a rotating shaft is fixedly installed on the other end face of the bevel gear set, and the rotating axis extends downward and is fixedly connected to the baffle.

[0008] As a further aspect of the present invention: the soil turning component moves along the Y-axis to turn the soil in an intermittent manner, that is, it first turns the soil at a certain position, and after the soil turning at that position is completed, it moves again, and so on until all positions under the same X coordinate point are turned.

[0009] As a further aspect of the present invention: the soil turning component moves a distance M from one turning point to the next, and the rotation angle of the rotating shaft corresponds to the distance M.

[0010] As a further embodiment of the present invention: a rotating wheel is fixedly installed at one end of the connecting shaft and inside the movable frame, and an inflation structure is fixedly installed on the side of the movable frame. The inflation structure includes a piston and a connecting rod, the connecting rod being connected to the rotating wheel. The inflation structure is also provided with a one-way air outlet valve and a one-way air inlet valve, and the one-way air outlet valve is connected to the soil turning component through a connecting hose.

[0011] As a further embodiment of the present invention: a fixing plate is fixedly installed above the soil turning component along its length, the fixing plate is connected to the connecting hose, and a plurality of evenly distributed air vents are provided inside the fixing plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are: This agricultural straw substrate fermentation equipment uses an intermittent movement method when the turning component moves along the Y-axis to turn the straw. It turns the straw at a certain location, then moves on to the next location, repeating this process until all locations at the same X-coordinate point are turned. During the movement from one turning point to the next, a distance M is traveled. The connecting gear rotates under the action of the connecting toothed plate, simultaneously driving the connecting shaft to rotate. This, in turn, causes the bevel gear set inside the moving frame to rotate, driving the rotating shaft to rotate. The angle of rotation corresponds to the distance M traveled, causing the lower baffle to rotate accordingly. Therefore, the baffle guides the higher pile of material at increasingly larger angles (spreading out in a fan shape), thus achieving a flat, evenly distributed pile effect.

[0015] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0016] like Figure 1The diagram shows the overall structure of an agricultural straw substrate fermentation device. The device includes a composting trough 10 and a turning mechanism 20 mounted on the composting trough 10 and moving along its length. The turning mechanism 20 includes a sliding plate 21. An X-axis moving assembly (not shown) is provided between the sliding plate 21 and the composting trough 10. The X-axis moving assembly can drive the sliding plate 21 to move on the composting trough 10. A Y-axis moving assembly 30 is provided inside the sliding plate 21. The Y-axis moving assembly 30 includes a lead screw 31 rotatably connected inside the sliding plate 21. One end of the lead screw 31 is connected to a driving component, which can be a stepper motor. A moving block 32 that can move along the Y-axis is meshed on the lead screw 31. A limiting groove 22 is provided inside the sliding plate 21. The moving block 32 moves within the limiting groove 22. The design of the limiting groove 22 improves the stability of the moving block 32's movement. A telescopic component 33 is fixedly installed at the lower end of the movable block 32. The telescopic component 33 can be a hydraulic rod. A soil-turning component 34 is fixedly installed at one end of the telescopic component 33. The soil-turning component 34 rotates to turn over the straw in the compost, thereby improving the straw fermentation effect.

[0017] Furthermore, such as Figure 2 As shown, an auxiliary component 40 is provided on the rear side of the moving block 32. The auxiliary component 40 includes a moving frame 41 fixedly connected to the rear side of the moving block 32. A connecting shaft 42 is rotatably connected between the moving frame 41 and the moving block 32, and a connecting gear 43 is sleeved on the connecting shaft 42. A connecting toothed plate 44 that meshes with the connecting gear 43 is fixedly installed inside the limiting groove 22. In this embodiment, the lead screw 31 is driven to rotate by the stepper motor. The lead screw 31 can drive the moving block 32 to move inside the limiting groove 22. On the one hand, it can drive the turning component 34 below to move along the Y-axis direction. On the other hand, it can also drive the auxiliary component 40 on the rear side to move. A baffle 45 is provided at the lower end of the moving frame 41. The baffle 45 can block the straw turned up by the turning component 34. The blocked straw will fall back into the manure pile and be piled up again. The specific working steps are as follows: When the soil turning component 34 turns the pile, it will move downward under the action of the telescopic component 33 to turn over the piled straw. When it descends to the standard height for turning, the turned-over material will splash up and hit the baffle 45. Because of the tilt angle of the baffle 45, the material will be guided in the greater tilt direction. For positions that are too high, as the turning proceeds, the high part can be transferred in the direction of movement, and finally the effect of even spreading can be achieved.

[0018] If the shading angle is changed during the shading process, it will affect the location of recomposting. Therefore, this application also proposes the following improvements.

[0019] like Figure 3As shown, the connecting shaft 42 extends outward into the interior of the moving frame 41 and connects to the bevel gear set 46. A rotating shaft 47 is fixedly installed on the other end face of the bevel gear set 46, and the rotating shaft 47 extends downward and is fixedly connected to the baffle 45. In this embodiment, during the turning process, the turning component 34 moves along the Y-axis in an intermittent motion. That is, it first turns the soil at a certain location, and after that location is turned, it moves again, repeating this process until all locations at the same X-coordinate point are turned. During the process of moving from one turning point to the next, the distance M is moved. The connecting gear 43 will rotate under the action of the connecting toothed plate 44. At the same time, the connecting shaft 42 will rotate synchronously, and the bevel gear set 46 inside the moving frame 41 will also rotate, driving the rotating shaft 47 to rotate. The angle of rotation corresponds to the distance M of movement. Consequently, the baffle 45 below will also rotate at a corresponding angle. Therefore, the angle of the baffle 45 guiding the higher pile of material is getting larger and larger (spreading out in a fan-shaped direction), thus achieving the effect of flat piling of material.

[0020] like Figure 4 and Figure 5 As shown, a rotating wheel 48 is fixedly installed at one end of the connecting shaft 42 and inside the movable frame 41. An inflation structure 49 is fixedly installed on the side of the movable frame 41. The inflation structure 49 includes a piston and a connecting rod, with the connecting rod connected to the rotating wheel 48. The inflation structure 49 is also equipped with a one-way exhaust valve and a one-way intake valve. The one-way exhaust valve is connected to the soil-turning assembly 34 via a connecting hose 50. In this embodiment, during the movement of the soil-turning assembly 34 a distance M, the connecting shaft 42 drives the rotating wheel 48 to rotate. The rotating wheel 48 drives the piston to move inside the inflation structure 49 via the connecting rod. The gas generated can then act on the soil-turning assembly 34 through the connecting hose 50, blowing air onto the moving soil-turning assembly 34. This blows off any straw and debris remaining on the soil-turning assembly 34, preventing it from affecting subsequent soil-turning operations.

[0021] A fixed plate 60 is fixedly installed above the soil turning component 34, which is distributed along its length. The fixed plate 60 is connected to the connecting hose 50, and multiple evenly distributed air vents are provided inside the fixed plate 60. The gas generated by the inflation structure 49 passes through the connecting hose 50 and then acts on the soil turning component 34 through the air vents in the fixed plate 60, blowing away the debris in the soil turning component 34.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
