Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a tiller with a leveling component. Background Technology

[0002] With the large-scale advancement of agricultural mechanization and ecological restoration projects in high-altitude areas, tillage machines, as core tillage equipment, are mainly used to break up compacted soil layers, improve soil aeration, and bury weed residues and surface gravel, creating basic conditions for the germination of Kentucky bluegrass and crested wheatgrass seeds. However, the soil in high-altitude areas is affected by long-term low-temperature freeze-thaw cycles, resulting in a loose structure that easily forms hard clods. After traditional tillage, a large number of large-diameter soil clods are easily left on the surface, and obvious furrows and ridges are easily generated during the tillage process, leading to uneven surface and extremely poor flatness. In addition, the strong winds in high-altitude areas make the exposed furrows and ridges after tillage susceptible to wind erosion, further exacerbating the unevenness of the surface and accelerating soil moisture loss, thus destroying the microenvironment required for seed germination.

[0003] Current methods for post-farmland treatment require separate leveling using soil shredders or manual labor. This step-by-step approach not only increases the time and labor intensity of agricultural production but also makes it difficult to guarantee the quality of the work. If the farmland is not level enough, the seeds will be planted at inconsistent depths during subsequent sowing operations. Some seeds will be buried too deep and fail to sprout, while others will be buried too shallow and easily dry out. Ultimately, this results in low germination rates and uneven growth of crops, seriously affecting crop yield and quality.

[0004] Therefore, this utility model proposes a tillage machine with a leveling component to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the existing technology of tillage machines with leveling components, such as large clods of soil and uneven ground after tillage, resulting in uneven sowing depth, uneven seedling growth, and low efficiency of manual leveling, this utility model aims to provide a tillage machine with leveling components that has been structurally improved and can effectively solve the above problems.

[0006] This utility model provides a tillage machine with a leveling component, including a fixed rod 1, with multiple disc rakes arranged on the lower side of the bottom of the fixed rod 1, a cylinder fixedly connected to one side of the fixed rod 1, a connecting rod connected to the output end of the cylinder, multiple connecting blocks connected to one side of the connecting rod, the bottom of the connecting blocks connected to the disc rakes, a fixed frame fixedly connected to the inner middle of the fixed rod 1, an electric push rod rotatably connected to the top of the fixed frame, a connecting frame rotatably connected to the output end of the electric push rod, a tire connected to the bottom of the connecting frame, and a crushing mechanism connected to the left end of the fixed rod 1. The crushing mechanism includes a fixed rod 2 fixedly connected to the top of the fixed rod 1, a telescopic rod 2 slidably connected to the top surface of the fixed rod 2, a traction rope connected to the left end of the telescopic rod 2, and a leveling floor connected to the bottom end of the traction rope.

[0007] The disc rake is driven by a cylinder to adjust the angle of entry into the soil, the tires are driven by an electric push rod to adjust the height and pressure, and the flat floor is flexibly dragged by a traction rope to adapt to the undulations of the ground.

[0008] Preferably, a triangular support and a telescopic rod are rotatably connected to the top right side of the fixed rod one. The telescopic rod one is fixedly connected to the outer top of the triangular support. The triangular support, the telescopic rod one, and the fixed rod one form a triangular structure. The stability of the triangular structure enhances the structural strength and load-bearing capacity of the connection between the overall device and the tiller. The output end of the cylinder is rotatably connected to the connecting rod, and the connecting block is rotatably connected to the disc rake via a hinge shaft. The cylinder drives the disc rake to deflect around the hinge shaft. This connection method can convert the linear motion of the cylinder into the angular deflection motion of the disc rake, thereby flexibly adjusting the cutting angle of the disc rake to adapt to soils of different hardness. Bolts are threaded to both ends of the fixed rod two. The ends of the bolts pass through the fixed rod two and abut against the outer wall of the telescopic rod two. By tightening the bolts, the telescopic rod two can be locked in the required position, thereby adjusting the working range of the tail crushing mechanism according to the width of the furrows in the cultivated land.

[0009] Preferably, the flat floor is a long steel channel structure or two short channel steel structures. The two ends of the flat floor are respectively connected to the bottom of the traction rope. The channel steel structure has a large mass, which can increase the downward pressure on the ground and improve the flatness and compaction effect. The flat floor can be selected as a long steel channel structure or two short channel steel structures according to actual needs, so as to cover different work areas.

[0010] Preferably, the connecting frame has an inverted U-shaped structure, with both ends of the tire connected to the two sides of the open end of the connecting frame. The inverted U-shaped structure provides stable dual-point support, ensuring that the tire is evenly stressed during leveling operations and is less prone to tilting. The fixed frame includes two vertically arranged support plates, with the electric push rod located between the two support plates. The top of the electric push rod protrudes from the top surface of the fixed rod. The support plate structure provides a stable mounting base for the electric push rod, ensuring the stability of the push rod's movement.

[0011] Preferably, the telescopic rod two slides horizontally along the length of the fixed rod two. The traction rope is made of steel wire rope or high-strength nylon rope, which allows for convenient and quick horizontal sliding adjustment. The high-strength flexible traction rope can withstand large drag forces and buffer the impact of the ground, preventing breakage caused by rigid connections. Multiple disc rakes are evenly distributed along the axis of the fixed rod one. The leveling mechanism is located between the disc rakes and the crushing mechanism. The evenly distributed disc rakes ensure full coverage of the tillage width. The reasonable mechanism layout realizes a streamlined operation of crushing, leveling, and fine finishing.

[0012] This utility model has the following beneficial effects: 1. This utility model solves the problem of inconsistent sowing depth caused by large clods and uneven soil surface after tillage operation in existing technologies. It achieves the effects of refining soil particles, significantly improving the flatness of cultivated land, ensuring uniform sowing depth, and promoting uniform crop emergence and growth. It is equipped with a disc rake at the bottom of a fixed rod and an adjustable cylinder to adjust the angle of the soil for initial cutting and breaking. It is also equipped with a weighted flat floor driven by an electric push rod in the middle to smooth the ground. Finally, it is equipped with a flexible drag flat floor at the tail for final finishing.

[0013] 2. This utility model solves the problem that existing equipment is difficult to adapt to soil with different hardness and different tillage width requirements by setting a cylinder to drive the disc rake to change the soil entry angle, and using an electric push rod to control the lifting and pressing force of the tires. Combined with the adjustable width telescopic rod at the tail, it achieves the effect of realizing the automatic adjustment of crushing and leveling operations, increasing operational flexibility, optimizing the crushing adaptability according to different ground conditions, and improving agricultural production efficiency.

[0014] 3. This utility model solves the problems of weak load-bearing capacity of existing devices and easy breakage and damage of rigid connecting parts when working on undulating ground by setting a triangular support structure at the front end of the fixed rod and the telescopic rod, and using a flexible traction rope to drag the flat floor at the tail end. It achieves the effect of enhancing the overall structural strength, using flexible connection to buffer the impact of the ground, preventing equipment breakage, and extending the service life of the equipment.

The fixed rod 1 serves as the basic support component of the overall device. A triangular brace 201 and a telescopic rod 202 are rotatably connected to the top right side of the fixed rod 1. The telescopic rod 202 is fixedly connected to the top outer side of the triangular brace 201. The triangular brace 201, the telescopic rod 202, and the fixed rod 1 form a stable triangular structure to enhance the connection strength.

An electric push rod 206 is rotatably mounted on the top of the fixing frame 209 via a pin. The telescopic end of the electric push rod 206 extends vertically upward through the through hole on the top surface of the fixing rod 1 and extends above the fixing rod 1. The top of the electric push rod 206 is hinged to the middle of the connecting frame 207 via a rotating bearing. The connecting frame 207 adopts an inverted U-shaped steel structure design. The connecting frame 207 spans across the top of the fixing rod 1, and its two side arms extend downward to both sides of the fixing rod 1. The bottom ends of the two side arms of the connecting frame 207... The cylinder 203 is fixedly connected to both ends of the tire 208. At the same time, a cylinder 203 is fixedly installed on the side wall of the fixing rod 1 by bolts 302. The cylinder 203 is arranged parallel to the axis of the fixing rod 1. The piston rod end of the cylinder 203 is hinged to one end of the connecting rod 204 through a joint bearing. The connecting rod 204 extends along the side of the fixing rod 1.

The top of the disc rake 4 is provided with a hinge hole that cooperates with the rotating shaft. When the cylinder 203 drives the connecting rod 204 to perform axial reciprocating motion, the connecting block 205 drives the disc rake 4 to deflect around the rotating shaft, thereby realizing the continuous adjustment of the angle of the disc rake 4 entering the soil.

[0022] To enhance the structural strength of the connection between the device and the traction power source and to prevent deformation at the connection point, please refer to... Figure 1 and Figure 6 The top right side of the fixed rod 1 is rotatably connected to the triangular brace 201 and the telescopic rod 202 via a pin. The telescopic rod 202 is welded and fixed to the top of the outer side of the triangular brace 201. The triangular brace 201 and the telescopic rod 202 are connected end to end with the fixed rod 1 to form a stable triangular support structure.

[0023] To adjust the tail-end breaking range according to different widths of furrows, please refer to... Figure 1 and Figure 6 The second fixing rod 301 is welded and fixed to the front and rear sides of the top of the first fixing rod 1. A straight groove is opened on the top surface of the second fixing rod 301. The second telescopic rod 303 is slidably engaged in the groove. Threaded through holes are opened on the side walls at both ends of the second fixing rod 301. Bolts 302 are screwed into the threaded through holes. The end of the bolt 302 passes through the side wall of the second fixing rod 301 and abuts against the outer wall surface of the second telescopic rod 303. The position of the second telescopic rod 303 is locked by tightening the bolts 302.

[0024] To improve the wear resistance of the traction connection and prevent breakage, the traction rope 304 is made of high-strength multi-strand steel wire rope or wear-resistant nylon rope. One end of the traction rope 304 is fixed to the end of the telescopic pole 303 by a lock buckle, and the other end of the traction rope 304 is fixed to the flat floor 306. The flat floor 306 adopts a channel steel structure to ensure sufficient downward pressure on the ground. Multiple disc rakes 4 are distributed in an equally spaced array along the length of the fixed pole 1 to ensure that no area is missed during cultivation.

[0025] Working principle: When the tiller moves the fixed rod 1 forward to till the land, the operator first controls the cylinder 203 to start. The piston rod of the cylinder 203 extends and retracts, pushing the connecting rod 204 to move along the side of the fixed rod 1. The connecting rod 204 drives the connecting block 205 to rotate, thereby changing the angle between the disc harrow 4 and the forward direction. The rotating disc harrow 4 cuts into the soil and cuts and breaks up the large clods of soil after tilling.

[0026] According to the required working width, the bolts 302 are loosened in advance and the position of the telescopic rod 303 on the fixed rod 301 is adjusted by sliding and then tightened again. As the device moves forward, the telescopic rod 303 drags the flat floor 306 behind it through the flexible traction rope 304. The flat floor 306 slides against the ground by its own weight, crushing and breaking up the small soil clods remaining on the ground and finally smoothing and tidying up the surface of the cultivated land. This flexible dragging connection method effectively avoids rigid breakage of the connecting parts due to excessive ground undulation. Thus, the efficient leveling of the cultivated land is completed through three processes: crushing, leveling and dragging.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
