Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0020] figure 1 and figure 2 It is a left view and a rear view of an embodiment of a traction-type hole depth-adjustable drilling machine. The traction-type hole depth-adjustable punching machine is made up of frame 1, power transmission device, punching device, return device and depth-limiting wheel 27. Wherein, the power transmission device is placed on the frame 1, and the power output by the tractor is transmitted to the punching device. There are 2 groups of punching devices, which are symmetrically distributed and installed on both sides of the rear side of the frame 1, and the punching devices complete the punching action by reciprocating motion.

[0021] The frame 1 includes a frame...

Abstract

A pull-type hole-depth-adjustable perforating machine comprises a rack (1), a power transmission device, perforating devices, a returning device and depth limiting wheels (27), wherein the rack (1) comprises a rack main beam (2), two upper hanging frames (3) and two lower hanging frames (4); the power transmission device comprises a gearbox (5) and a belt transmission mechanism, and the perforating devices are distributed symmetrically and respectively connected to the belt transmission mechanism; the returning device comprises a supporting arm (19), a returning connection rod (18) and a spring rod (20); and the two depth limiting wheels (27) are distributed symmetrically and respectively firmly connected on two sides of the rack main beam (2) and comprise rocker arms (28) and wheels (29).

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a traction-type hole-depth-adjustable punching machine. Background technique [0002] Soil salinization refers to the process in which the salt in the bottom soil or groundwater rises to the surface with the capillary water, and after the water evaporates, the salt accumulates in the surface soil. Soil salinization is one of the most prominent production eco-environmental problems in arid and semi-arid agricultural regions in the world, the main obstacle to the sustainable development of regional agriculture, and the most common land degradation process. Soil salinization is not conducive to plant growth, affects yield, and threatens the sustainable development and utilization of regional land resources. [0003] Among the existing measures to remediate degraded soil, the most common way is land leveling. Leveling the land can make the water infiltrate evenly, im...
