Detailed Description

Example 1:

as shown in figures 1, 2 and 3, when the greenhouse deep ploughing machine is used, the tractor is connected with the transverse adjusting device 29, and can deeply plough places where other machines can not plough through transverse adjustment. The transverse adjustment implementation method comprises the following steps: the hydraulic cylinder 31 connected to the hinged block 22 on the support is extended when hydraulic pressure is applied so that the other hinged point connected to the lateral adjustment device is moved relative to the green house deep ploughing machine. Power is transmitted to a gearbox 1 through a universal joint, the gearbox 1 adopts gear transmission, the contact area between the box body and the ground when the box body is buried is reduced as much as possible, the power is transmitted to two cutter shafts 2 through the gearbox 1, each cutter shaft 2 fixes a deep-turning shovel 28 through a disc type cutter frame 3, two deep-turning cutters 28 are installed on each disc type cutter frame 3, two cutter storehouses 4 are arranged outside a support side plate 8, and the greenhouse deep-turning machine can be buried more easily. Every two adjacent disc type tool rests 3 rotate 90 degrees relatively along the cutter shaft 2. The tool bit of the deep-turning shovel 28 is arranged at the side edge of the tip end, one of the tool handles of the deep-turning shovel 28 is connected with the tool bit at the side close to the tip end, and the other tool handle is connected with the turning surface of the tool bit at the side close to the tip end. The deep ploughing shovels 28 are small in arrangement number, small in shovel distance and compact in working area, and power consumption can be reduced. The soil planing position of the cutter head is edged and inclined towards the center line of the working shaft. Thus, the resistance to penetration into the ground can be reduced by setting the shape of the cutter after use.

The deep ploughing shovels 28 and the middle furrow plough 33 on the two sides of the bracket side plate 8 can enable the greenhouse deep ploughing machine to easily dig into the soil and reduce the traction resistance; the cutter shaft 2 of the greenhouse deep ploughing machine is slowly pressed into the soil layer through a tractor hydraulic device. The side view of the welding part of the tool shank and the tool bit of each deep ploughing shovel 28 is triangular, so that the side view can play a role of a reinforcing rib and increase the welding area of the tool bit and the tool shank, so that the deep ploughing shovel is more stable, soil is ploughed by the deep ploughing shovel 28 with low rotating speed, and then the ploughed soil is overturned uniformly by the ploughing plate 26 welded on the disc type tool rest 3 to reach the depth of 30 centimeters; the thrown soil is collided with the rear soil covering plate 25, the soil can be finely crushed, the ground can be smoothed, the soil covering force is automatically adjusted by the spring 14 behind the soil covering plate 25, and the smoothing angle can be changed by changing the axial length of the spring.

The preferred embodiments of the present invention disclosed above are intended only to help illustrate the present invention. The preferred embodiments are not intended to be exhaustive or to limit the invention to the precise embodiments disclosed.
