Description

Technical Field

[0002] In recent years, with the continuous advancement and development of technology, various agricultural machinery, such as rotary tillers and field levelers, have been widely used in the cultivation of vast farmlands.

[0003] Field-leveling machinery plays an important role in land consolidation work, usually using heavy rollers or leveling plates to compact and level the land. These methods can effectively complete land consolidation tasks in most cases. However, traditional methods may face challenges in specific soil types such as clay or soils rich in root and stem debris. Clay soil, due to its sticky properties, easily adheres to the rollers or leveling plates of field-leveling machinery, thereby affecting the efficiency of the machinery. In addition, compacted clay soil may become harder, forming a hard block structure that is difficult to break, which has an adverse effect on crop growth. In response to these problems, we need to further explore and innovate land consolidation methods to adapt to different types of soil conditions and provide stronger support for agricultural production.

[0004] In view of this, we propose an agricultural machinery field leveling device. Utility Model Content

The end of the rotating shaft away from the pear wheel is fixedly connected to one end of the reciprocating screw.

[0008] As a further improvement of the technical solution, the upper end of the protrusion and the lower end of the push rod are both designed to be arc-shaped.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In recent years, with the continuous advancement and development of technology, various agricultural machinery, such as rotary tillers and field levelers, have been widely used in the cultivation of vast farmlands.

[0024] Field leveling machines play an important role in land preparation, usually using heavy rollers or leveling plates to compact and level the land. These methods are effective in most cases. However, in certain soil types such as clay or soils rich in root and stem debris, traditional methods may face challenges. Clay soils, due to their sticky nature, tend to adhere to the rollers or leveling plates of field leveling machines, which in turn affects the efficiency of the machine. In addition, compacted clay soils may become harder, forming a hard block structure that is difficult to break, which has an adverse effect on crop growth. Clay soil is a type of soil with sticky properties, which makes it easy to adhere to the rollers or leveling plates of field leveling machines. When clay soil adheres to these machine parts, it will affect the efficiency of the machine. This is because the sticky nature of clay soil makes it difficult to completely remove, which increases the burden and difficulty of the machine.

[0025] In addition, clay soils may become harder after compaction, forming a hard block structure that is difficult to break. The formation of this hard block structure has an adverse effect on crop growth. First, the hard block structure will hinder the growth and expansion of plant roots, limiting the plant's ability to absorb water and nutrients. Second, the hard block structure will also increase the density of the soil, resulting in a decrease in the voids in the soil, thereby affecting the aeration and permeability of the soil. These factors will have a negative impact on the growth and development of crops, reducing the yield and quality of crops.

[0027] Pear wheels 201 are installed on both sides of the field leveling machine 200. The pear wheels 201 rotate by being pulled by the agricultural tractor 100 on the front side. The pear wheel 201 is fixedly connected to an axle 204 at the axis center. The axle 204 improves the working stability of the pear wheel 201. The end of the axle 204 away from the pear wheel 201 is rotatably connected to the side wall of the field leveling machine 200. The side wall of the field leveling machine 200 is rotatably connected to a rotating shaft 308. The rotating shaft 308 drives the reciprocating screw rod 304 to rotate by rotating. The outer wall of the rotating shaft 308 and the outer wall of the axle 204 are rotatably connected with a belt 307. The end of the rotating shaft 308 away from the pear wheel 201 is fixedly connected to one end of the reciprocating screw rod 304, so that the axle 204 transmits power to the rotating shaft 308 through the belt 307, so that the rotating shaft 308 drives the reciprocating screw rod 304 to rotate.

[0028] The improvement of this embodiment is that:

[0029] The agricultural tractor 100 pulls the field leveler 200 to perform operations and drives the pear wheel 201 to rotate. The rotation of the pear wheel 201 further drives the reciprocating screw rod 304, so that it drives the push rod 305 to reciprocate left and right on the upper side of the vibration plate 301. Since a plurality of bumps 306 are provided on the upper side of the vibration plate 301, the push rod 305 will produce intermittent downward thrust on the vibration plate 301 when passing through these bumps 306. At the same time, springs 303 are connected to both sides of the vibration plate 301, so that each time the push rod 305 is pushed down, the vibration plate 301 can be moved up and reset by the action of the spring 303, thereby producing an effect of up and down vibration. This vibration has an effect on the land, can effectively loosen and break the soil, make the soil particles more evenly distributed, improve the air permeability and permeability of the soil, and promote the growth and development of the root system. In addition, vibration can also eliminate gaps and cracks in the soil, increase the density and stability of the soil. This is of great significance for reducing water evaporation, maintaining soil moisture, and increasing crop growth and yield.

[0030] Considering the fluency, smoothness and efficiency of the vibration system, the upper end of the protrusion 306 and the lower end of the push rod 305 are both designed to be arc-shaped, so that the push rod 305 can be smoother when passing through the protrusion 306.

[0031] Considering that the field leveling machine 200 can work more efficiently, quickly and stably, a suspension frame 203 is installed on the upper side of the field leveling machine 200, and a plurality of buckets 202 are fixedly connected to the front side of the field leveling machine 200. A hook 101 is rotatably connected to the top of the suspension frame 203, and an end of the hook 101 away from the suspension frame 203 is rotatably connected to an agricultural tractor 100, so that the field leveling machine 200 can perform efficient field leveling work driven by the agricultural tractor 100.

[0032] When the utility model agricultural machinery field leveling device is used, the staff connects the field leveling machine 200 to the agricultural tractor 100 through the hook 101, and after the agricultural tractor 100 is started, the field leveling machine 200 is pulled on the land surface. In this process, the bucket 202 performs the operation of crushing and turning over the land, and at the same time, the pear wheel 201 starts to rotate, thereby driving the wheel shaft 204 to rotate. The rotation of the wheel shaft 204 drives the rotating shaft 308 to rotate through the belt 307. The rotation of the rotating shaft 308 further drives the reciprocating screw 304 to rotate. The reciprocating screw 304 drives the push rod 305 to perform left and right reciprocating motion inside the slide rail 300 through the meshing transmission mechanism. During this movement, the lower end of the push rod 305 continuously pushes up the protrusion 306 on the upper side of the vibration plate 301, thereby stimulating the vibration plate 301 to generate intermittent downward thrust. However, the springs 303 connected to both sides of the vibration plate 301 ensure that each time the push rod 305 is pushed down, the vibration plate 301 can rise and reset with the help of the elastic force of the springs 303, thereby generating an up and down vibration effect.
