Description

Technical Field

[0001] The invention belongs to the field of agricultural tillage equipment, and in particular relates to a lightweight paddy field crawler tillage machine. Background Art

[0002] A crawler tiller is an agricultural machine that utilizes a crawler-type travel system. Its large contact patch and strong adhesion make it suitable for operations in complex terrain and diverse soil types, combining high efficiency, versatility, and intelligent operation. A crawler tiller uses tracks instead of traditional tires, with the engine driving the tracks in a circular motion to propel the machine forward. The tracks increase the contact area with the soil, distributing the machine's weight and reducing soil pressure, effectively preventing sinking and slipping in soft, wet fields.

[0003] Existing tracked tillers typically require a towed implement for tilling the fields. However, these implements are typically stationary, relying solely on the movement of the machine for passive tillage. Limited by the tiller's speed, tillage efficiency is low, often requiring repeated operations. Existing dynamic tillage equipment often requires additional power sources to drive the implements, resulting in complex structures and hindering lightweighting. Summary of the Invention

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0033] See also Figures 1 to 5 The present invention provides a lightweight paddy field crawler tillage machine, comprising:

[0034] A tillage machine 1, comprising:

[0035] The machine body 11 is provided with a control module and a drive module for controlling the movement of the crawler tiller;

[0036] Two driving wheels 12 are symmetrically mounted on both sides of the body 11 via a driving shaft 121. The driving shaft 121 is movable and extends into the body 11 to be transmission-connected to the driving module in the body 11.

[0037] Two guide wheels 13 are mounted on both sides of the machine body 11 so as to rotate symmetrically around the central axis;

[0038] Two crawlers 14 are movably mounted on the driving wheels 12 and guide wheels 13 on both sides of the machine body 11;

[0039] The handrail 2 is fixed to the side of the machine body 11 by bolts;

[0040] The tillage component 3 is used for tilling the surface soil of the paddy field, and includes:

[0041] Two connection boxes 31 are symmetrically located on both sides of the tiller 1 and are sealed and connected by a box body 311 and a sealing cover 312;

[0042] The two driven shafts 33 are connected to the driving shaft 121 through a transmission unit 32 movably installed in the connecting box 31. The outer sides of the two driven shafts 33 are fixedly installed with turning rollers 34. The two driven shafts 33 are movably connected together by the connecting sleeve 35.

[0043] In actual application, the present invention drives the driving shaft 121 to rotate through the driving module in the body 11, thereby driving the driving wheel 12 to rotate, and the guide wheel 13 tightens the track 14 to drive the track 14 to rotate, thereby driving the entire tillage machine to move. The driven shaft 33 connected to the driving shaft 121 is driven to rotate while the tillage machine moves as a whole, and the tillage roller 34 is used to turn the surface soil of the paddy field.

[0044] The present invention transmits the rotational torque of the drive shaft 121 to the driven shaft 33 through the connection box 31 and the transmission unit 32, and drives the tillage roller 34 to rotate through the driven shaft 33 to realize the tillage of the surface soil of the paddy field. Compared with the existing passive tillage machine, the tillage efficiency and stability are improved, no additional power source is required, and the lightweight structure is achieved. By movably connecting the two independently set driven shafts 33 using the connecting sleeve 35, when the tillage machine changes direction, the two driven shafts 33 and the tillage roller 34 can be driven to rotate normally by the drive shaft 121. Compared with the existing integrated tillage roller, the tillage roller can avoid being affected by the torsional stress caused by the speed difference on both sides when the tillage machine turns, thereby reducing the physical damage of the connecting sleeve 35 and improving the service life of the equipment.

[0045] In one case of this embodiment, the driven shaft 33 and the tiller roller 34 can also be replaced by other traction agricultural implements that require axial rotation to achieve functions such as rotary tillage, furrowing, fertilizing, sowing, spraying pesticides, and weeding, thereby reducing purchase costs by achieving multiple uses of one machine.

[0046] See also Figure 2 As another preferred embodiment of the present invention, the tiller 1 also includes two mounting frames 15 symmetrically mounted on both sides of the machine body 11, and a plurality of load-bearing wheels 16 and track-supporting rollers 17 are rotatably mounted on the mounting frames 15 through a central axis, and the load-bearing wheels 16 and track-supporting rollers 17 are in rolling contact with the inner side of the crawler 14.

[0047] In actual application, the present invention directly bears the weight of the machine body 11 through the provided load-bearing wheels 16 and disperses the pressure to the crawler 14, and supports the upper branch section of the crawler 14 through the provided track rollers 17, thereby reducing vibration and impact during travel.

[0048] See also Figure 2 and Figure 3 As another preferred embodiment of the present invention, the transmission unit 32 includes a driving sprocket 321 and a driven sprocket 322. The driving sprocket 321 and the driven sprocket 322 are rotatably installed in the connecting box 31 through a wheel core, and the wheel core movably penetrates the side wall of the connecting box 31 and extends to the outside of the connecting box 31. The driving sprocket 321 and the driven sprocket 322 are connected by a meshing chain 323.

[0049] Furthermore, a mounting groove 123 is fixedly provided at the shaft end of the driving shaft 121 , and a transmission column 122 is clamped in the mounting groove 123 . The transmission column 122 is configured as a prism with a regular polygonal cross section.

[0050] Furthermore, the transmission column 122 movably passes through the core of the driving sprocket 321 and extends to the other side of the driving sprocket 321 , and the shaft end of the driven shaft 33 movably passes through the connecting box 31 and is fixedly connected to the driven sprocket 322 .

[0051] In actual application of the present invention, the driving sprocket 321 is driven to rotate by the transmission column 122, and the driven sprocket 322 is driven to rotate by the chain 323, and then the driven shaft 33 and the turning roller 34 are driven to rotate by the driven sprocket 322. Based on the relative rotation of the driving sprocket 321 and the driven sprocket 322 and the connecting box 31, the connecting box 31 only provides support and is not affected by the movement of the drive shaft 121 and the transmission unit 32, thereby ensuring that the height position of the driven shaft 33 and the turning roller 34 remains unchanged.

[0052] See also Figure 1 As another preferred embodiment of the present invention, the tillage component 3 also includes a mudguard 36 fixedly mounted on the two connecting boxes 31 through a connecting plate 361. The mudguard 36 is configured as an arc-shaped plate. The mudguard 36 is wrapped around the outside of the two tillage rollers 34 to prevent mud and water from splashing back.

[0053] In actual application, the mud guard 36 is provided to cover the outside of the tilling roller 34, thereby preventing mud and water from splashing on the tilling roller 34 when the tiller is working, ensuring the cleanliness of the equipment and the operator, and improving the comfort of the operator.

[0054] See also Figure 1 、 Figure 2 and Figure 5 As another preferred embodiment of the present invention, the tillage assembly 3 further includes a fixing rod 37 horizontally connecting the two connection boxes 31 , and the middle portion of the fixing rod 37 is fixedly connected to the handrail 2 through an adjusting rod 38 .

[0055] Furthermore, the adjusting rod 38 includes an upper mounting seat 381 and a lower mounting seat 382 fixedly mounted on the handrail 2 and the middle of the fixed rod 37. The upper mounting seat 381 is movably hinged to one end of the adjusting screw rod 383, and the lower mounting seat 382 is movably hinged to one end of the movable rod 384. The other end of the adjusting screw rod 383 is movably extended into the movable rod 384, and the other end of the movable rod 384 is rotatably mounted with an adjusting sleeve 385 that is compatible with the outer thread of the adjusting screw rod 383.

[0056] In actual application, the present invention cooperates with the movable rod 384 through the adjustment screw 383 movably hinged on the upper mounting seat 381 and the lower mounting seat 382, and the overall length of the adjustment rod 38 is adjusted by rotating the adjustment sleeve 385, and then cooperates with the fixed handrail 2 and the fixed rod 37 to adjust the inclination angle of the connecting box 31, thereby improving the flexibility of the driven shaft 33 and the turning roller 34.
