Description

Technical Field

[0001] This invention relates to the agricultural field, specifically to an offset, foldable, towable compost turner. Background Technology

[0002] In modern agricultural production, the treatment of compost materials is a key link in realizing resource recycling and improving soil fertility.

[0003] A compost turner is a mechanical device used in the composting process to turn and process materials, such as livestock and poultry manure and crop straw, into high-quality organic fertilizer, improving soil structure and increasing soil fertility. A traditional compost turner typically consists of a frame, power system, turning device, and walking mechanism. With the coordinated operation of these components, a traditional compost turner can generally handle relatively simple daily material turning tasks.

[0004] However, currently used crop turners are often designed with a relatively large lateral width, and most notably, they lack any flexible adjustment functions such as telescopic or folding capabilities. This means that when busy agricultural production operations come to an end and the equipment needs to be parked, it occupies a considerable amount of space. Furthermore, because it cannot effectively shorten its length when parked, if other agricultural operations are being carried out nearby, operators are highly susceptible to accidental collisions. Once a collision occurs, the fragile components of the crop turner may suffer varying degrees of damage, undoubtedly significantly shortening the equipment's expected lifespan, increasing agricultural production costs, and reducing production efficiency.

[0005] Based on this, the present invention is proposed. Summary of the Invention

[0021] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0022] 1. The present invention provides an offset foldable traction composting material turning machine, which, through the cooperation of a reducer and a sprocket transmission assembly, enables the turning drum to rotate, uses a double helical blade assembly to turn the fertilizer on the ground, and uses a nozzle assembly to spray clean water or additives from the storage tank, which is conducive to the composting work.

[0023] 2. The extension and retraction of the hydraulic cylinder in this invention can realize the unfolding or folding of the arc-shaped cover, ensuring that the arc-shaped cover can be unfolded when in use and folded after use, thus greatly reducing the width of the equipment when not in use, saving the equipment's floor space, and avoiding damage caused by collisions when the equipment is parked.

[0024] 3. In this invention, a driving mechanism is used to drive the turntables in the leveling assembly to rotate back and forth. A connecting rod causes each turntable to rotate back and forth, which in turn causes each lever to move back and forth. This allows the fertilizer to be leveled after turning and spreading, preventing uneven fertilizer distribution that could lead to inconsistent composting results.

[0025] 4. In this invention, the rotation of the turntable can be linked with the pressure rod to make the protrusion descend, thereby causing the rotating frame to rotate and the pressure roller to move up and down repeatedly. The pressure roller can break up clumps of fertilizer and avoid affecting the uniformity of composting.

[0026] In summary, this invention can efficiently turn over and spread fertilizer on the ground; simultaneously, it can spray water or additive solutions to aid composting. Furthermore, it can unfold an arc-shaped shield before operation and retract it afterward, significantly reducing the equipment width and saving floor space. Moreover, it can precisely level the fertilizer after turning and automatically break up clumps, ensuring uniform composting and comprehensively improving the quality and efficiency of composting operations.

[0044] Example 1

[0045] like Figure 1 , Figure 2 and Figure 3As shown, the offset foldable towable compost turner includes: an offset tow frame 1, a hinged connection mechanism 2, an arc-shaped baffle 3, a turning drum 4, a double-helix blade assembly 5, a reducer 6, a sprocket drive assembly 7, a hydraulic cylinder 8, a liquid storage tank 9, a water pump 10, a nozzle assembly 11, and rubber hoses 12. One side of the offset tow frame 1 is foldably connected to the arc-shaped baffle 3 via the hinged connection mechanism 2. At least two first wheels 100 are mounted on the offset tow frame 1, and a second wheel 200 is mounted on the side of the arc-shaped baffle 3 away from the offset tow frame 1 for easy towing of the equipment. The radius of curvature of the arc-shaped baffle 3 is 1.2~1.5m. The hinged connection mechanism 2 includes a hinged support 2a and a rotating arm 2b. The hinged support 2a is fixed to the offset tow frame 1. The rotating arm 2b is fixedly connected to the arc-shaped shield 3. The rotating arm 2b is connected to the hinged support 2a via a pin, ensuring that the two can rotate relative to each other. The two ends of the hydraulic cylinder 8 are respectively hinged to the offset traction frame 1 and the arc-shaped shield 3. The hydraulic cylinder 8 acts as a folding control mechanism, which can drive the arc-shaped shield 3 to unfold or retract relative to the offset traction frame 1. The unfolding angle of the arc-shaped shield 3 is controlled by hydraulic telescopic control. In the unfolded state, the working length of the turning drum 4 is 4.5m, and the length is shortened to 2.1m after retraction. The turning drum 4 is rotatably installed inside the arc-shaped shield 3, and its axis is perpendicular to the traction direction. The surface of the turning drum 4 is provided with a double helical blade group 5, which includes a left-handed blade array 5a and a right-handed blade array 5b. The left-handed blade array 5a and the right-handed blade array 5b are arranged symmetrically to each other along the axial direction of the turning drum 4. Both the left-handed blade array 5a and the right-handed blade array 5b consist of multiple blades with serrated cutting edges, a cutting edge angle of 25°~35°, and a blade spacing of 100~150mm. The reducer 6 and the sprocket drive assembly 7 are both mounted on the offset traction frame 1, together forming the power transmission system. The reducer 6 drives the turning drum 4 to rotate via the sprocket drive assembly 7. The sprocket drive assembly 7 includes: a flexible coupling 7a, a driving sprocket 7b, a driven sprocket 7c, and a drive chain 7d. There are two flexible couplings 7a, one end of which is connected to the 90-degree turning shaft end of the reducer 6. The other end of one flexible coupling 7a is connected to the output end of an external power output motor. The driving sprocket 7b is rotatably mounted on the arc-shaped baffle 3, and the driving sprocket 7b is fixedly connected to the other end of the other flexible coupling 7a. Driven sprocket 7c is rotatably mounted on the arc-shaped baffle 3, and is fixedly connected to one end of the turning drum 4. Driven sprocket 7c and driving sprocket 7b are arranged parallel to each other at intervals. A transmission chain 7d is sleeved between the driving sprocket 7b and driven sprocket 7c, driving the turning drum 4 to rotate. In this embodiment, the flexible coupling 7a is a cross-shaft universal coupling, with a maximum deflection angle of 20°~30° between its input and output ends.A liquid storage tank 9 is fixed to an offset traction frame 1. A water pump 10 is installed on the liquid storage tank 9 using a flange seal. The suction end of the water pump 10 is connected to the liquid storage tank 9. A nozzle assembly 11 is installed on the inner front end of an arc-shaped baffle 3 and is connected to the water pump 10 via a rubber hose 12. The liquid storage tank 9, water pump 10, and nozzle assembly 11 together constitute a spraying system, which moves synchronously as the arc-shaped baffle 3 folds. The nozzle assembly 11 in the spraying system includes multiple sets of fan-shaped atomizing nozzles, each evenly distributed along the inner front end of the arc-shaped baffle 3. A flow regulating valve is also installed on the rubber hose 12 to control the flow rate of the sprayed liquid. A first counterweight 13 is fixed below the liquid storage tank 9. A second counterweight 14 is fixed to the offset traction frame 1 and located on the opposite side of the unfolding direction of the arc-shaped baffle 3. The first counterweight 13 and the second counterweight 14 are made of cement and are used to maintain the balance of the equipment. In addition, a traction arm 1a is installed on the offset traction frame 1 for connecting to the traction equipment. The center of gravity offset of the offset traction frame 1 is 0.8~1.2m. The traction point of the traction arm 1a is located on one side of the longitudinal axis of the offset traction frame 1, and the offset direction is opposite to the unfolding direction of the arc-shaped baffle 3, so as to ensure the stability of the traction equipment when it moves as a whole and avoid tilting.

[0046] The specific working principle of the above structure is as follows: During use, the traction arm 1a is connected to the tractor, and the flexible coupling 7a, which is not connected to the drive sprocket 7b, is connected to an external motor. The external motor is turned on, and through the speed regulation transmission of the reducer 6 and the flexible coupling 7a, the drive sprocket 7b rotates. This, in turn, in conjunction with the transmission chain 7d, drives the driven sprocket 7c to rotate, thereby rotating the turning drum 4. The double-helix blade array 5 turns and scatters the fertilizer on the ground. The inclined left-hand blade array 5a and right-hand blade array 5b ensure the sharpness of the blades when cutting into the material, using their serrated edges to sharply cut the fertilizer fibers, while also cleverly reducing cutting resistance, thus reducing energy consumption. Simultaneously, it ensures the continuity of the turning and scattering operation. Simultaneously, water pump 10 is activated. Under the suction and pressure of water pump 10, the clean water in storage tank 9 flows smoothly through rubber hose 12 to nozzle assembly 11, where it is pre-sprayed evenly onto the compost to be turned, preventing fertilizer from flying during turning. Spray assembly 11 can also be used to add additives to the compost. Continuous operation can be achieved by moving the tractor to pull the equipment. After operation, hydraulic cylinder 8 is activated, causing its output end to retract, pulling the arc-shaped cover 3 to fold as... Figure 2 As shown.

[0047] The aforementioned structure enables automatic turning and spreading of fertilizer on the ground, while simultaneously spraying water to prevent dust from flying. Furthermore, the curved cover 3 automatically folds after use, reducing the equipment's footprint and preventing accidental damage.

[0048] Example 2

[0049] During the turning and spreading process, the compost on the ground can easily clump together, leading to uneven fermentation. Therefore, the solution proposed in this embodiment is used to level the compost after turning and spreading. The specific solution is as follows, for reference. Figure 4 , Figure 5 , Figure 7 and Figure 8 A leveling assembly is installed inside the arc-shaped baffle 3 to level the fertilizer on the ground. The leveling assembly includes: a fixed plate 20, a limiting groove 201, a turntable 21, a first connecting post 22, a connecting rod 23, a second connecting post 24, a moving rod 25, and a lever 26. The fixed plate 20 is fixedly installed inside the arc-shaped baffle 3. There are several sets of limiting grooves 201, each set of limiting grooves 201 being equidistantly opened on the fixed plate 20, and each set of limiting grooves 201 contains two mutually symmetrical arc-shaped grooves. There are several turntables 21, which are equidistantly rotatably installed on the fixed plate 20. The first connecting post 22 is installed on the turntable 21, and two first connecting posts 22 are symmetrically installed on the upper surface of each turntable 21. The linkage 23 is rotatably connected to the first connecting post 22. The linkage 23 is used to associate the first connecting posts 22 at corresponding positions on each turntable 21, ensuring that when one turntable 21 rotates, all turntables 21 can rotate synchronously under the linkage 23. The second connecting post 24 is installed on the lower surface of the turntable 21 and is slidably installed in the limiting groove 201, which can limit the second connecting post 24. The moving rod 25 is rotatably installed at the bottom end of the second connecting post 24. The lever 26 is installed at the bottom end of the moving rod 25 and is L-shaped. The lever 26 is divided into two groups and is symmetrically installed at the bottom ends of the two moving rods 25.

[0050] When in use, the above structure drives one of the turntables 21 to rotate back and forth. Through the linkage of the connecting rod 23, all the turntables 21 rotate synchronously. At the same time, each of the second connecting posts 24 can slide back and forth in the limiting groove 201, thereby causing the two second connecting posts 24 to move back and forth in opposite directions. This causes the two sets of levers 26 to swing back and forth alternately, thus leveling the fertilizer on the ground.

[0051] refer to Figure 4 The arc-shaped baffle 3 is also equipped with a drive mechanism 27, which drives the turntable 21 to rotate reciprocally. (Reference) Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 10As shown, the drive mechanism 27 includes: a first mounting bracket 2701, a drive column 2702, a first sliding groove 2703, a rotating cylinder 2704, a second sliding groove 2705, a sliding rod 2706, a sliding plate 2707, a fixed cylinder 2708, a blind groove 2709, a second mounting bracket 27010, a drive seat 27011, a drive slot 27012, a first bevel gear 27013, a second bevel gear 27014, a rotating shaft 27015, a connecting bracket 27016, and a motor 27017. The first mounting bracket 2701 is installed inside the arc-shaped baffle 3. The drive column 2702 is rotatably mounted on the first mounting bracket 2701. The first sliding groove 2703 is formed on the drive column 2702 with its ends connected, and there is a height difference between the top and bottom of the first sliding groove 2703. A rotating cylinder 2704 is mounted on the outside of the drive column 2702. A second sliding groove 2705 is formed on the rotating cylinder 2704, and the second sliding groove 2705 is inclined, with its height difference matching that of the first sliding groove 2703. A sliding rod 2706 passes through the first sliding groove 2703 and the second sliding groove 2705, and the first sliding groove 2703 and the second sliding groove 2705 together limit the sliding rod 2706. A sliding piece 2707 is mounted on the end of the sliding rod 2706 away from the drive column 2702. A second mounting bracket 27010 is mounted inside the arc-shaped baffle 3, and a fixed cylinder 2708 is mounted on the second mounting bracket 27010, with the rotating cylinder 2704 located inside the fixed cylinder 2708. A blind groove 2709 is formed inside the fixed cylinder 2708, and a sliding piece 2707 is slidably installed in the blind groove 2709. The blind groove 2709 can limit the sliding piece 2707, ensuring that the sliding rod 2706 and the sliding piece 2707 can only move along the direction of the blind groove 2709. A drive base 27011 is installed at the bottom end of the rotating cylinder 2704. A drive groove 27012 is formed on the drive base 27011, and a first connecting post 22 is installed in the drive groove 27012. A first bevel gear 27013 is fixedly installed on the drive post 2702. A connecting bracket 27016 is installed on the first mounting bracket 2701. A rotating shaft 27015 is rotatably installed on the connecting bracket 27016. The second bevel gear 27014 is mounted on one end of the rotating shaft 27015 and meshes with the first bevel gear 27013, ensuring that the rotation of the second bevel gear 27014 can drive the first bevel gear 27013 to rotate synchronously, thus realizing the vertical transmission of driving force. The motor 27017 is mounted on the side wall of the arc-shaped baffle 3, and the output end of the motor 27017 is connected to the other end of the rotating shaft 27015. Turning on the motor 27017 can drive the rotating shaft 27015 and the second bevel gear 27014 to rotate.

[0052] The specific usage method of the above structure is as follows: First, the motor 27017 is turned on to drive the rotating shaft 27015 and the second bevel gear 27014 to rotate, which in turn drives the first bevel gear 27013 and the drive column 2702 to rotate synchronously. While the drive column 2702 rotates, the first sliding groove 2703 limits the sliding rod 2706, and the blind groove 2709 limits the sliding piece 2707, causing the sliding rod 2706 to move up and down. The second sliding groove 2705 limits the sliding rod 2706, causing the rotating cylinder 2704 to rotate. For every one rotation of the drive column 2702, the first sliding groove 2703 rotates synchronously, and the sliding rod 2706 moves up and down a round trip due to the limitation of the first sliding groove 2703, causing the rotating cylinder 2704 to rotate once. This causes the drive seat 27011 to swing back and forth once, and the drive groove 27012 limits the first connecting column 22, causing the corresponding turntable 21 to rotate once. This allows lever 26 to begin the leveling process. The above structure enables the lever 26 to swing back and forth, with precise structure and simple operation.

[0053] It is worth noting that both the leveling component and the drive mechanism 27 are installed on the side of the arc-shaped baffle 3 away from the direction of equipment movement, ensuring that the fertilizer can be leveled after turning and scattering. Furthermore, some fertilizer tends to clump together during spraying; to facilitate breaking up these clumps, the following solution is proposed: [Reference] Figure 4 , Figure 5 and Figure 11 Two connecting pieces 28 are symmetrically mounted on the fixed plate 20. A rotating frame 29 is rotatably mounted between the two connecting pieces 28. A pressure roller 30 is mounted on the end of the rotating frame 29 away from the fixed plate 20. A protrusion 31 is mounted on the rotating frame 29, and the protrusion 31 and the pressure roller 30 are located on opposite sides of the connection between the rotating frame 29 and the connecting piece 28, ensuring that pressing down on the protrusion 31 can lift the pressure roller 30. A pressure rod 32 is mounted on the turntable 21. The pressure rod 32 can swing with the rotation of the turntable 21. When the pressure rod 32 contacts the protrusion 31, it can press it down, causing the pressure roller 30 to lift. When the pressure rod 32 leaves the contact state with the protrusion 31, the pressure roller 30 falls back to the ground, striking the fertilizer on the ground and breaking up clumps. The protrusion 31 is trapezoidal, ensuring that the pressure rod 32 can press down on the protrusion 31 smoothly.

[0054] The above specific embodiments do not limit the scope of protection of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
