Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically a dual-shaft rotary tillage assembly for weeding chestnut forests. Background Technology

[0002] In chestnut forests, weeds compete with chestnut trees for nutrients, water, and sunlight. Rotary tillers, as commonly used agricultural machinery, play a crucial role in weed control within chestnut forests. They mechanically turn over the soil, altering the weed's growth environment, helping to maintain a healthy ecosystem in the chestnut forest, and creating suitable conditions for chestnut tree growth.

[0003] Utility model patent CN220586774U discloses a combined rotary tiller and weeder for orchards. This machine includes a frame, with a support plate fixedly connected to the outer surface of the frame. A motor is fixedly connected to the top of the support plate. Fixing bolts penetrate the outer surface of the mounting plate to secure two sets of bushings. Multiple sets of rotary blades are fixed to the outside of the drive shaft. Starting the motor drives the transmission assembly, which in turn rotates the drive shaft, thus driving the rotary blades for rotary tilling and weeding. Since weeding in orchard areas may involve hard soil or rocks, if one set of rotary blades is damaged during weeding, workers can quickly disassemble and replace it by removing the fixing bolts on one set of bushings. This eliminates the need to replace the entire set of blades, reducing the time spent replacing weeding components and improving weeding efficiency.

[0004] The existing orchard rotary tiller primarily relies on the rotation of the blades to turn over and cover weeds during operation. However, this structure only turns the weeds into the soil and cannot effectively cut them, resulting in the weed roots and stems remaining intact. Even after being covered, the weeds can still take root and regrow, affecting the durability of the weeding effect. In view of this, we propose a dual-shaft rotary tiller assembly for weeding chestnut forests. Utility Model Content

[0017] Preferably, the double-groove pulley has two grooves for mounting belts, one groove is connected to the driven pulley by a belt, and the other groove is connected to the diesel engine output pulley on the rotary tiller by a belt.

[0018] In this configuration, the two grooves of the double-groove pulley can transmit power to the passive pulley and receive power from the diesel engine, respectively, enabling a single power source to drive the operation of two mechanisms.

[0019] Preferably, the rotating shaft passes through the partition and is rotatably connected to the partition, and the partitions separate the plurality of crushing components;

[0020] In this setup, the rotating shaft is rotatably connected to the partition plate without affecting its rotation, and the partition plate separates the crushing components to prevent mutual interference during operation.

[0021] Preferably, the blades are distributed in multiple layers, and the blades are arranged in a ring array on the outside of the fixed sleeve with the fixed sleeve axis as the center;

Subsequently, the rotary tillage blades further mix the crushed weeds with the soil for covering. During this process, the weeds lose their complete growth structure after being crushed and are difficult to regrow after being covered, thus improving the durability of the weeding effect.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example 1

[0039] Please see Figures 1-3 A dual-shaft rotary tiller assembly for weeding chestnut forests includes a frame assembly 100, within which a rotary tiller mechanism 200 is installed. The frame assembly 100 includes a cover 110 and two beams 120 fixed to the left and right ends of the cover 110. The cover 110 provides protection for the rotary tiller mechanism 200, preventing soil and weeds from splashing outwards during rotary tillage. A crossbeam 122 is fixed between the ends of the two beams 120, enhancing the stability of the connection between the two beams 120. The ends of the two beams 120 are connected to the main body of the rotary tiller, thus achieving the installation and fixation of the frame assembly 100 and the main body of the rotary tiller.

[0040] In this invention, the rotary tillage mechanism 200 includes a rotating shaft 210 and several rotary tillage blades 220. A reducer 211 is coaxially connected to the rotating shaft 210. The reducer 211 can adjust the input speed to achieve a suitable rotary tillage speed for the rotating shaft 210. A double-grooved pulley 212 is coaxially connected to the input shaft of the reducer 211. The double-grooved pulley 212 is used to transmit power. A cover 110 encloses the rotary tillage mechanism 200. The input shaft of the reducer 211 passes through the beam 120 and extends to the outside of the beam 120. The double-grooved pulley 212 is located on the outside of the cover 110. The double-grooved pulley 212 has two grooves for mounting a belt. One of the grooves is connected to the output pulley of the diesel engine on the rotary tiller via a belt drive, transmitting the power of the diesel engine to the reducer 211.

[0041] Specifically, a number of rotary tillage blades 220 are arranged in a circular array around the axis of the rotating shaft 210. This arrangement allows the rotary tillage blades 220 to evenly turn over the soil. The end of the rotating shaft 210 away from the reducer 211 passes through a corresponding beam 120 and is rotatably connected to the beam 120. The beam 120 provides support for the rotating shaft 210, ensuring stable rotation. A number of connecting discs 230 are fixed to the outside of the rotating shaft 210. The rotary tillage blades 220 are fixed to the outer surface of the connecting discs 230. The connecting discs 230 provide installation positions for the rotary tillage blades 220, allowing the rotary tillage blades 220 to be securely connected to the rotating shaft 210.

[0042] In this embodiment, the dual-shaft rotary tillage assembly for weeding chestnut forests is used as follows: First, the ends of the two beams 120 are connected and fixed to the main body of the rotary tiller. One groove of the double-grooved pulley 212 is connected to the output wheel of the diesel engine on the rotary tiller by a belt. Then, the diesel engine is started, and the power is transmitted to the double-grooved pulley 212 via the belt, and then to the rotating shaft 210 via the reducer 211, causing the rotating shaft 210 to start rotating. Next, the rotating shaft 210 drives the rotary tillage blades 220 on the connecting plate 230 to rotate, performing rotary tillage on the soil. Finally, during the rotary tillage process, the cover 110 protects the rotary tillage mechanism 200 to prevent soil and weeds from splashing.

[0043] Example 2

[0044] like Figure 1 and Figures 4-6 As shown, a crushing mechanism 300 is provided at the front end of the frame assembly 100. A protruding rod 121 is fixed at the bottom position of the ends of the two beams 120. The protruding rod 121 provides a mounting support point for the rotating shaft 320. The crushing mechanism 300 includes a separating assembly 310 installed between the ends of the two beams 120, a rotating shaft 320 rotatably connected between the two protruding rods 121, and several crushing components 330 sleeved and fixed around the rotating shaft 320.

[0045] like Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment, the separating component 310 includes a fixing rod 311 fixed between the ends of two beams 120 and several partitions 312 evenly distributed between the ends of the two beams 120. The fixing rod 311 fixes the partitions 312 to ensure the stability of the partitions 312. The fixing rod 311 passes through the partitions 312 and is fixedly connected to the partitions 312. The partitions 312 can separate adjacent crushing components 330 to avoid mutual interference between the crushing components 330 during operation.

[0046] like Figure 4 and Figure 5 As shown, specifically, the rotating shaft 320 passes through the partition 312 and is rotatably connected to the partition 312. The partition 312 does not affect the rotation of the rotating shaft 320, but at the same time plays a certain limiting role for the rotating shaft 320. The end of the rotating shaft 320 is coaxially connected to a driven pulley 321. The driven pulley 321 is sleeved in another groove on the double groove pulley 212, so that the driven pulley 321 and the double groove pulley 212 are connected by a belt. Through belt drive, the double groove pulley 212 can transmit power to the driven pulley 321, thereby driving the rotating shaft 320 to rotate.

[0047] like Figure 1 , Figure 4 and Figure 6 As shown, furthermore, several partitions 312 separate several crushing components 330. The crushing components 330 are distributed within the spaces formed by two adjacent partitions 312. Each crushing component 330 includes a fixing sleeve 331 and several blades 332 disposed on the outer periphery of the fixing sleeve 331. The fixing sleeve 331 can securely fix the crushing component 330 on the rotating shaft 320 and rotate with the rotating shaft 320. The blades 332 are distributed in multiple layers, forming a circular array around the axis of the fixing sleeve 331 on the outer side of the fixing sleeve 331. The multi-layered and circular arrayed blades 332 can more comprehensively crush weeds and improve the crushing effect. Several connecting plates 333 are fixed in a circular array around the axis of the fixed sleeve 331 on the outer peripheral surface of the fixed sleeve 331. The number of connecting plates 333 is the same as the number of blades 332. The blades 332 are fixed on the connecting plates 333. The connecting plates 333 provide mounting connection points for the blades 332, so that the blades 332 are securely mounted on the fixed sleeve 331.

[0048] It is worth noting that the reducer 211 involved in this utility model is a conventional technology and will not be described in detail here.

[0049] In this embodiment, the dual-shaft rotary tillage assembly for weeding chestnut forests first transmits power to the driven pulley 321 via a belt through the double-groove pulley 212, causing the rotating shaft 320 to rotate and the crushing mechanism 300 to start working. Then, the rotating shaft 320 drives the blades 332 on the fixed sleeve 331 to rotate within the space formed by the adjacent partitions 312, thus pre-crushing the weeds that have entered the space formed by the adjacent partitions 312. Finally, the crushed weeds are moved with the equipment to the rotary tillage mechanism 200, where the rotary tillage blades 220 further mix and cover them with the soil, completing the weeding operation.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
