Description

Technical Field

[0001] The present invention relates to the field of deep tillage machines, and in particular to a vibrating soil deep tillage machine. Background Art

[0002] At present, in agricultural cultivation, deep soil loosening is an effective means to change the growth of crop planting. Deep soil loosening refers to the use of deep loosening machines to loosen the 5 to 15 cm plow bottom layer below the tillage layer, loosen the soil and deepen the thickness of the loose soil layer. As an important technology of soil cultivation, deep loosening has received more and more attention at home and abroad. Due to long-term plowing or stubble removal operations on the land, the plow bottom layer of the soil will float up, the tillage layer will become shallower, and finally soil erosion will intensify and the soil will gradually degrade. The more the soil degrades, the lower the farmers' income and the lower the production efficiency. Soil deep loosening technology can break the soil compaction and deepen the tillage layer. Soil deep loosening can break the hard plow bottom layer formed by plowing or stubble removal for many years, increase the thickness of the tillage layer, and create good soil conditions for the normal growth of crops. Breaking the plow bottom layer can improve soil permeability, thereby improving the soil's water, fertilizer, gas and heat coordination ability, improve soil fertility level and buffering capacity, and increase field water holding capacity. Soil deep tillage technology can greatly improve the soil's ability to store water and retain moisture. After mechanical deep tillage, the soil can absorb more rainwater, establish a good "soil reservoir" to reduce surface runoff, and avoid soil erosion. More importantly, it can store rainwater in summer and autumn in the soil to achieve the effect of storing water and retaining moisture.

[0003] When the existing subsoiler is operating, the traction resistance of the subsoiler increases with the increase of the subsoil depth. At present, four-row subsoiling requires medium-to-high-power tractors, which increases the subsoiling cost and fuel consumption. In addition, the large size of high-power tractors makes it difficult to turn at the end of the field. The vibration mechanism of the existing vibrating subsoiler is a cantilever structure, which results in a long shaft length, resulting in a large bearing pressure at the other end of the cantilever. The vibration of the vibrating subsoiler also causes the vibration of the tractor, which can easily cause discomfort to the tractor driver.

[0004] For this reason, a vibrating soil deep tiller is needed to solve this problem. Summary of the invention

[0005] The purpose of the present invention is to provide a vibrating soil deep tiller, aiming to solve the problems raised in the background technology.

A piston is provided in the damping sleeve, and the piston is connected to the shock absorbing shaft, and the shock absorbing shaft is connected to the vibration back plate. A shock absorbing spring is sleeved on the outer side of the shock absorbing shaft.

[0012] Preferably, a vibrator is provided between the middle plate and the vibrating back plate, a plurality of spring-tooth plowshare fixing plates are connected to the bottom surface of the vibrating back plate, reinforcing plates are provided between the spring-tooth plowshare fixing plates, the spring-tooth plowshare fixing plates are provided with fixing through holes, the fixing through holes are engaged with fixing screws, vibration springs are provided on both sides of the spring-tooth plowshare fixing plates, the vibration springs are connected to the vibration groove, and a deep loosening shovel is connected to the outer side of the vibration groove.

[0014] Beneficial effect: When the electromagnetic coil housing of the present invention is energized, an electromagnetic field is generated inside it and acts on the magnet at one end of the main shaft, so that the main shaft is suspended in the electromagnetic coil housing without mechanical contact, thereby reducing the contact friction and wear of the cantilever bearing and reducing the bearing pressure. At the same time, the frame adopts an arched structure to enhance the structural stability, and the main shaft on the frame is connected to the main support plate through a stabilizer bar to further reduce the pressure on the cantilever structure bearing and provide stability for the cantilever structure. A vibration spring is provided between the vibration groove connected to the deep loosening shovel of the present invention and the spring-tooth plow shovel fixing plate. When subjected to vibration force, the vibration amplitude is larger, which is more stable than that of a rigid shovel. The deep tillage shovel has a better drag reduction effect, can reduce traction resistance, and has a better deep tillage effect. At the same time, the spiral rod can be driven to rotate by rotating the turntable, thereby changing the preload force of the adjustment spring to adapt to soils with different physical properties, thereby obtaining an ideal deep tillage effect and effectively reducing the tillage resistance of the machine. When the vibrator is used to vibrate, the vibration back plate of the present invention will squeeze the shock-absorbing spring to cause deformation, and at the same time, the shock-absorbing shaft will drive the piston to move in the damping sleeve, and the vibration energy will be consumed by compressed air, thereby reducing the vibration force transmitted upward from the bottom, minimizing the vibration of the tractor caused by vibration, and avoiding physical discomfort to the tractor driver.

[0029] First, the tractor is fixedly connected to the tractor through the tractor connecting rod 43 to drive the deep tiller to move.
