Description

Technical Field

[0001] The invention relates to the field of agriculture, and in particular to an offset foldable traction-type compost material turner. Background Art

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

[0003] A composting machine is a mechanical device used to turn materials during the composting process. It processes organic waste such as livestock and poultry manure and crop straw, converting it into high-quality organic fertilizer, improving soil structure and fertility. Traditional composting machines typically consist of a frame, power system, turning mechanism, and travel mechanism. These components work together to effectively handle simple, everyday composting tasks.

[0004] However, the horizontal width of the tiller currently in use is often designed to be relatively wide in terms of the equipment's overall dimensions, and the most prominent problem is that it does not have flexible adjustment functions such as telescopic and folding. This means that when busy agricultural production operations come to a halt and the equipment needs to be parked after use, it will occupy a considerable area of site space. In addition, since it cannot effectively shorten its own length when parked, if other agricultural operations are being carried out in the surrounding area at the same time, it is very easy for the operator to accidentally collide with it if he is not careful. Once an accidental collision occurs, the fragile parts of the tiller may suffer varying degrees of damage, which will undoubtedly significantly shorten the equipment's originally expected normal service life, increase agricultural production costs, and reduce production efficiency.

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

Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0029] Example 1

[0030] like Figure 1 、 Figure 2 and Figure 3As shown, the offset foldable traction type compost material turner includes: an offset traction frame 1, an articulated connection mechanism 2, an arc-shaped shield 3, a turning roller 4, a double spiral blade group 5, a reducer 6, a sprocket transmission assembly 7, a hydraulic cylinder 8, a liquid storage tank 9, a water pump 10, a nozzle assembly 11 and a rubber pipe 12. One side of the offset traction frame 1 is foldably connected to the arc-shaped shield 3 through the articulated connection mechanism 2. At least two first wheels 100 are installed on the offset traction frame 1, and a second wheel 200 is installed on the side of the arc-shaped shield 3 away from the offset traction frame 1 to facilitate towing the equipment. The curvature radius of the arc-shaped shield 3 is 1.2~1.5m. The articulated connection mechanism 2 includes an articulated support 2a and a rotating arm 2b. The articulated support 2a is fixed to the offset traction frame 1. The rotating arm 2b is fixedly connected to the arc-shaped shield 3, and the rotating arm 2b is connected to the hinged support 2a through a pin shaft to ensure 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 serves as a folding control mechanism to drive the arc-shaped shield 3 to expand or retract relative to the offset traction frame 1, and the expansion angle of the arc-shaped shield 3 is controlled by hydraulic telescoping. In the expanded state, the working length of the flipping drum 4 is 4.5m, and the length is shortened to 2.1m after retraction. The flipping drum 4 is rotatably installed in the arc-shaped shield 3, and its axis is perpendicular to the traction direction. A double helical blade group 5 is provided on the surface of the flipping drum 4. The double helical blade group 5 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 along the axis of the flipping drum 4. Both the left-handed blade array 5a and the right-handed blade array 5b are composed of multiple blades, and the blade edges adopt a serrated structure with an edge inclination angle of 25° to 35° and a blade spacing of 100 to 150 mm. The speed reducer 6 and the sprocket transmission assembly 7 are both mounted on the offset traction frame 1, and the two together constitute a power transmission system. The speed reducer 6 drives the flipping drum 4 to rotate through the sprocket transmission assembly 7. The sprocket transmission assembly 7 includes: a flexible coupling 7a, a driving sprocket 7b, a driven sprocket 7c and a transmission chain 7d. There are two flexible couplings 7a, one end of each of the two flexible couplings 7a is connected to the 90-degree steering shaft end of the speed reducer 6. The other end of one of the flexible couplings 7a is connected to the output end of an external power output motor. The driving sprocket 7b is rotatably mounted on the arc-shaped shield 3, and the driving sprocket 7b is fixedly connected to the other end of the other flexible coupling 7a. A driven sprocket 7c is rotatably mounted on the curved shield 3 and fixedly connected to one end of the flipping drum 4. The driven sprocket 7c is spaced parallel to the driving sprocket 7b. A transmission chain 7d is looped between the driving and driven sprockets 7b, driving the flipping drum 4. In this embodiment, the flexible coupling 7a is a cross-axis universal coupling with a maximum deflection angle of 20° to 30° between its input and output ends.A liquid reservoir 9 is fixed to the offset traction frame 1. A water pump 10 is mounted to the reservoir 9 using a flange seal. The suction port of the water pump 10 is connected to the reservoir 9. A spray head assembly 11 is mounted on the inner front end of the curved shield 3 and connected to the water pump 10 via a rubber pipe 12. The liquid reservoir 9, water pump 10, and spray head assembly 11 together constitute the spraying system, which moves synchronously with the folding of the curved shield 3. The spray head assembly 11 in the spraying system includes multiple sets of fan-shaped atomizing nozzles, evenly distributed along the inner front end of the curved shield 3. A flow control valve is also installed on the rubber pipe 12 to control the flow rate of the sprayed liquid. A first counterweight 13 is fixed below the liquid reservoir 9. A second counterweight 14 is fixed to the offset traction frame 1, located on the opposite side of the curved shield 3 when it is deployed. The first and second counterweights 13, 14 are made of cement and are used to maintain balance. Furthermore, the offset traction frame 1 is equipped with a traction arm 1a for connecting to the traction equipment. The center of mass of the offset traction frame 1 is offset by 0.8 to 1.2 meters. The traction point of the traction arm 1a is located to one side of the longitudinal axis of the offset traction frame 1, and the offset direction is opposite to the direction in which the arc-shaped shield 3 is deployed. This ensures the stability of the traction equipment during overall movement and prevents skew.

[0031] The specific working principle of the above structure is as follows: when in use, the traction arm 1a is connected to the tractor, and the flexible coupling 7a that is not connected to the driving sprocket 7b is connected to the external motor. The external motor is turned on and the speed regulation transmission is transmitted through the reducer 6 and the flexible coupling 7a, so that the driving sprocket 7b rotates, and then cooperates with the transmission chain 7d to drive the driven sprocket 7c to rotate, driving the turning drum 4 to rotate, and the double-helical blade group 5 is used to turn the fertilizer on the ground. The inclined left-handed blade array 5a and the right-handed blade array 5b can not only ensure the sharpness of the blade when cutting into the material, and with its serrated edge, it can sharply cut the fertilizer fiber, but also cleverly reduce the resistance during cutting, thereby reducing energy consumption and reducing cutting resistance, reducing energy consumption. At the same time, the continuity of the turning operation is guaranteed. At the same time, the water pump 10 is turned on synchronously. Under the suction and pressure transmission of the water pump 10, the clean water in the liquid storage barrel 9 flows smoothly to the nozzle assembly 11 through the rubber pipe 12, and is evenly sprayed on the fertilizer to be turned over in advance by the nozzle assembly 11 to prevent the fertilizer from flying when turning over. The nozzle assembly 11 can also be used to add additives to the compost. The tractor pulling equipment can continue to work. After the operation is completed, the hydraulic cylinder 8 is turned on to retract its output end, and the arc-shaped shield 3 is pulled to fold as shown. Figure 2 shown.

[0032] The above structure can realize automatic turning over of the fertilizer on the ground, and can spray clean water while turning over to avoid dust. At the same time, the arc-shaped shield 3 can be automatically folded after use, reducing the floor space of the equipment and avoiding damage caused by accidental contact with the equipment.

[0033] Example 2

[0034] During the turning process, the compost on the ground is likely to gather, which in turn leads to inconsistent compost fermentation. Therefore, the solution proposed in this embodiment is used to level the fertilizer after turning. The specific solution is as follows, refer to Figure 4 、 Figure 5 、 Figure 7 and Figure 8 , a leveling assembly is installed on the inner side of the arc-shaped shield 3, and the leveling assembly can level the fertilizer on the ground. The leveling assembly includes: a fixed plate 20, a limiting groove 201, a turntable 21, a first connecting column 22, a connecting rod 23, a second connecting column 24, a moving rod 25 and a shifting rod 26. The fixed plate 20 is fixedly installed on the inner side of the arc-shaped shield 3. There are several groups of limiting grooves 201, and each group of limiting grooves 201 is equidistantly opened on the fixed plate 20, wherein each group of limiting grooves 201 has two mutually symmetrical arc grooves. There are several turntables 21, which are equidistantly rotatably installed on the fixed plate 20. The first connecting column 22 is installed on the turntable 21, and two first connecting columns 22 are symmetrically installed on the upper surface of each turntable 21. The connecting rod 23 is rotatably connected to the first connecting column 22. The connecting rod 23 is used to associate the first connecting columns 22 at corresponding positions on each turntable 21 to ensure that when one turntable 21 rotates, each turntable 21 can rotate synchronously under the linkage of the connecting rod 23. The second connecting column 24 is installed on the lower surface of the turntable 21, and the second connecting column 24 is slidably installed in the limit groove 201. The limit groove 201 can limit the second connecting column 24. The moving rod 25 is rotatably installed at the bottom end of the second connecting column 24. The shifting rod 26 is installed at the bottom end of the moving rod 25, and the shifting rod 26 is L-shaped. The shifting rod 26 is divided into two groups, which are symmetrically installed at the bottom ends of the two moving rods 25.

[0035] When in use, the above structure drives one of the rotating discs 21 to rotate back and forth, and the rotating discs 21 rotate synchronously through the linkage of the connecting rod 23. At the same time, each second connecting column 24 can slide back and forth in the limiting groove 201, thereby causing the two second connecting columns 24 to reciprocate in opposite directions, thereby causing the two sets of shifting rods 26 to swing back and forth in an interlaced manner, thereby leveling the fertilizer on the ground.

[0036] refer to Figure 4 The arc-shaped shield 3 is also equipped with a driving mechanism 27, which can drive the turntable 21 to rotate back and forth. Figure 5 、 Figure 6 、 Figure 8 、 Figure 9 and Figure 10As shown, the drive mechanism 27 includes: a first mounting frame 2701, a drive post 2702, a first chute 2703, a rotating cylinder 2704, a second chute 2705, a sliding rod 2706, a sliding plate 2707, a fixed cylinder 2708, a blind slot 2709, a second mounting frame 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 frame 27016, and a motor 27017. The first mounting frame 2701 is mounted within the arc-shaped shield 3. The drive post 2702 is rotatably mounted on the first mounting frame 2701. The first chute 2703 is formed on the drive post 2702, and has a height difference between the upper and lower directions. The rotating cylinder 2704 is mounted on the outside of the drive column 2702. A second chute 2705 is defined within the rotating cylinder 2704. The second chute 2705 is angled, with a height difference that matches the height difference of the first chute 2703. A slide bar 2706 extends through both the first and second chute 2703 and 2705, which together limit the position of the slide bar 2706. A slide plate 2707 is mounted on the end of the slide bar 2706 away from the drive column 2702. A second mounting bracket 27010 is mounted within the curved shield 3. A fixed cylinder 2708 is mounted on the second mounting bracket 27010, with the rotating cylinder 2704 positioned within the fixed cylinder 2708. Blind groove 2709 is defined within fixed cylinder 2708, and slide 2707 is slidably mounted within blind groove 2709. Blind groove 2709 limits slide 2707, ensuring that slide rod 2706 and slide 2707 can only move in the direction of blind groove 2709. A drive seat 27011 is mounted at the bottom end of rotating cylinder 2704. A drive groove 27012 is defined within drive seat 27011, and first connecting post 22 is mounted within drive groove 27012. A first bevel gear 27013 is fixedly mounted on drive post 2702. A connecting frame 27016 is mounted on first mounting frame 2701. A rotating shaft 27015 is rotatably mounted on connecting frame 27016. The second bevel gear 27014 is mounted on one end of the rotating shaft 27015 and is meshed 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, thereby transmitting the driving force in a perpendicular direction. The motor 27017 is mounted on the side wall of the arc-shaped shield 3, and the output end of the motor 27017 is connected to the other end of the rotating shaft 27015. When the motor 27017 is turned on, the rotating shaft 27015 and the second bevel gear 27014 can be driven to rotate.

[0037] The above structure is specifically used as follows: First, turn on the motor 27017 to rotate the rotating shaft 27015 and the second bevel gear 27014, which in turn drives the first bevel gear 27013 and the drive column 2702 to rotate synchronously. As the drive column 2702 rotates, the first chute 2703 limits the position of the slide bar 2706, and the blind slot 2709 limits the position of the slide plate 2707, causing the slide bar 2706 to move up and down. The second chute 2705 limits the position of the slide bar 2706, causing the rotating cylinder 2704 to rotate. Each rotation of the drive column 2702 synchronizes with a rotation of the first chute 2703. The slide bar 2706, constrained by the first chute 2703, moves up and down one full rotation, causing the rotating cylinder 2704 to rotate once. This in turn causes the drive base 27011 to swing back and forth once, and the drive slot 27012 limits the position of the first connecting column 22, causing the corresponding turntable 21 to rotate once. The above structure can realize the reciprocating swing of the lever 26, and the structure is precise and easy to operate.

[0038] It is worth noting that the paving assembly and the driving mechanism 27 are both installed on the side of the arc shield 3 away from the forward direction of the equipment, ensuring that the fertilizer can be paved after being thrown. In addition, some fertilizers are prone to clumps due to the spraying process. In order to conveniently break up the clumps, the following solution is proposed: 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 respectively located on both sides of the connection between the rotating frame 29 and the connecting piece 28, ensuring that the pressure roller 30 can be lifted by pressing the protrusion 31. A pressure rod 32 is mounted on the turntable 21. The pressure rod 32 can swing as the turntable 21 rotates. When the pressure rod 32 contacts the protrusion 31, it can press it down, causing the pressure roller 30 to tilt up. When the pressure rod 32 leaves the contact state with the protrusion 31, the pressure roller 30 falls back to the ground, knocking the fertilizer on the ground to break up clumps. The protrusion 31 is trapezoidal in shape, ensuring that the pressure rod 32 can smoothly press down the protrusion 31.

[0039] 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.
