Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural equipment, in particular to a compactor. Background Art
[0002] When planting crops such as wheat, the soil is often loose after sowing, which makes it impossible for the seeds to be tightly combined with the soil, resulting in a low germination rate and low soil temperature. When the temperature drops, the seedlings are easily frozen to death and frostbitten, resulting in a low germination rate and serious marketing benefits. In the prior art, a traction-type pressing roller is often used, and the tractor drives the traction-type pressing roller to move and press, so as to narrow the gaps in the land and play a role in moisture conservation and temperature increase. However, when the traction-type pressing roller is in use, the tires of the tractor roll over the bottom surface as it passes by, causing part of the soil to be rolled over by the wheels, and part of the soil to be squeezed to both sides of the wheels. After the subsequent traction-type pressing roller is pressed, the soil is still uneven, and it is difficult to ensure the germination rate. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a soil compactor which can compact the soil uniformly.
[0004] In order to solve the above technical problems, the utility model includes a vehicle body, and its structural features are: an engine is provided on the vehicle body, a drive shaft that can be driven to rotate by the engine is provided at the rear of the vehicle body, a steering shaft that can rotate to adjust the forward direction of the vehicle body is provided on the front side of the vehicle body, a front pressing roller is installed on the steering shaft, rear pressing rollers are installed on the left and right ends of the drive shaft respectively, the distance between the two rear pressing rollers in the left and right directions is not greater than the width of the front pressing roller in the left and right directions, and a soil breaking chain that can fill the soil gaps after pressing is provided on the rear side of the vehicle body.
[0005] After adopting the above structure, the engine on the vehicle body drives the driving shaft to rotate, and the driving shaft is equipped with a rear crushing roller, and then the rear crushing roller acts as the rear wheel of the vehicle body to drive the vehicle body to move forward. While moving, the rear crushing roller uses the dead weight of the vehicle body to crush the ground it passes through. The vehicle body moves forward, and a front crushing roller is installed on the front steering shaft of the vehicle body. The front crushing roller also acts as the front wheel of the vehicle body to crush the passing road surface during the movement. By changing the direction of the steering shaft, the forward direction of the vehicle body is changed, and then the crushing position of the vehicle body is changed. The front crushing roller crushes the middle soil that the vehicle body passes through, and then the two rear crushing rollers crush the soil on both sides. Soil, the width of the soil that the pressing function can press is the width formed between the two rear pressing rollers, and the distance between the rear pressing rollers is not greater than the width of the front pressing roller in the left and right directions, thereby avoiding the formation of a gap between the front and rear pressing rollers after pressing, which causes part of the soil or wheat seedlings to not be pressed, thereby ensuring the uniformity and efficiency of the pressing. The soil after pressing is more compact, which plays a role in retaining entropy and increasing temperature, and improves the seedling rate of crops. After pressing, the soil-breaking chain located on the rear side of the vehicle body breaks up the surface soil, and the soil-breaking chain is used to fill the gaps in the soil after pressing, thereby further achieving the effect of retaining entropy and increasing temperature, thereby ensuring the seedling rate and improving economic benefits.
[0006] The front pressing roller is composed of a plurality of front wheels, and each rear pressing roller is composed of a plurality of rear wheels. The tires facilitate installation and maintenance, and are easy to adapt to uneven ground, avoiding the skewness of the integrated pressing roller caused by uneven farmland, and better completing the soil pressing and improving the pressing efficiency.
[0007] The front wheels are provided with wavy patterns to increase the friction of the front wheels, thereby increasing the friction of the front pressing roller, making it easier to grip the ground and increasing the applicability of the pressing machine.
[0008] The rear wheels are provided with herringbone patterns, which increase the friction of the rear wheels, thereby increasing the friction of the rear pressure roller, making it easier to grip the ground and increasing the applicability of the pressure roller.
[0009] A rotatable front bracket is provided on the front side of the vehicle body, the steering shaft is installed on the lower side of the front bracket, and a shock absorbing device is installed between the front bracket and the steering shaft. By controlling the rotation of the front bracket and then the rotation of the steering shaft, the shock absorbing device reduces the vibration impact on the driver when moving forward and ensures the stability of the moving process.
[0010] The soil-breaking chain includes a rear bracket hinged to the vehicle body, the left and right width of the rear bracket is not less than the left and right width of the two rear pressing rollers, a metal chain capable of breaking up the soil on the lower side of the rear bracket is fixedly connected to the rear end of the rear bracket, and an adjustment device for adjusting the angle of the bracket is provided on the rear bracket, and the position of the metal chain is adjusted by the adjustment device so that the metal chain can contact the soil. At the same time, the width of the rear bracket is not less than the left and right width of the rear pressing rollers, thereby ensuring that the metal chain can break up the top of all the pressed land, and then let the broken up soil enter the gap, reducing the gaps in the soil, further achieving the effect of maintaining entropy and increasing temperature, and thus ensuring the emergence rate.
[0011] The rear bracket is provided with a plurality of lifting ears, and the metal chain is mounted on the lifting ears. The metal chain forms a plurality of annular metal chain rings. The plurality of annular metal chains not only play the role of crushing the soil but also play the role of hanging the crushed soil, thereby ensuring the filling effect of the soil. At the same time, one chain can be hung on a plurality of lifting ears to form a metal chain ring, which is convenient for installation and improves efficiency.
[0012] Two wheel covers are arranged on the rear side of the vehicle body, and the two wheel covers are respectively covered above the rear pressing rollers, so as to ensure the safety of the operator and the balance of the vehicle body.
[0013] In summary, the utility model has the advantages of being able to evenly compact the soil, reduce soil gaps, retain moisture and increase temperature, increase the germination rate, and improve efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
