Embodiment 1

[0012] A mechanical pneumatic subsoiler, connected to the rear of the tractor, including a vehicle frame 1 connected to the traction device at the rear of the tractor, an intermittent mechanism installed in the middle of the vehicle frame 1 and a high-pressure air injection device installed on the pulley 7, The pulley stop mechanism is fixed on the high-pressure air pump 2, the air pressure control system assembly 3, the hydraulic motor 18, the reduction box 16 and the electromechanical hydraulic control system assembly 19 at the front of the vehicle frame 1. The high-pressure air output port of the high-pressure air pump 2 is connected with the high-pressure air input port of the air gun 14 through the air pressure control system assembly 3, the hydraulic input port of the hydraulic motor 18 is connected with the hydraulic output port of the tractor, and the output shaft of the hydraulic motor 18 is connected through a coupling 17 is connected with the input shaft of the reduc...

Embodiment 2

[0014] Intermittent mechanism comprises the gear 4 that is installed on vehicle frame 1 front portion, the I-shaped slide rail 15 that is fixed on vehicle frame 1 rear portion, the tackle 7 that is assembled on the I-shaped slide rail 15 and the rack 6 that is installed on the tackle 7 . The input shaft of gear 4 is connected with the output shaft of reduction box 16, and meshes with rack 6, and rack 6 has guide groove. During the working process, when the gear 4 rotates in the toothed area, the gear 4 rotates to drive the rack 6 to move forward, and the traction block 7 moves forward relative to the I-shaped slide rail 15 fixed on the frame 1. When the gear 4 rotates to no When it is in the tooth zone, the block 7 stops moving, so that the high-pressure air injection device installed on the block 7 moves intermittently relative to the frame 1 .

Embodiment 3

[0016] The tackle stop mechanism comprises a stop push rod 10, a stop push rod support 11 and a ground support device 13, the stop push rod support 11 is fixed on the upper surface of the tackle 7, and one end of the stop push rod 10 is connected to the stop push rod. The bracket 11 is connected, and the other end is connected with the ground supporting device 13 . During the working process, when the trolley 7 moves forward relative to the I-shaped slide rail 15, the trolley stop mechanism fixed on the trolley 7 also moves accordingly. When the trolley 7 stops moving, the electromechanical hydraulic control system assembly 19 controls the stop push Rod 10 promotes and grips support device 13 and plunges into the ground surface, which can ensure that the high-pressure air injection device installed on the tackle 7 is relatively motionless on the ground.

Abstract

The invention discloses a mechanical air pressure subsoiler to solve the technical problems that an existing subsoiler is large in energy consumption and poor in subsoiling effect. According to the technical scheme, the mechanical air pressure subsoiler comprises a frame connected to the back portion of a tractor, a high-pressure air pump fixed to the front portion of the frame, an air pressure control system assembly, a mechanical electrohydraulic control system assembly, a hydraulic motor and a reduction gearbox, and is characterized by further comprising an intermittent mechanism, a high-pressure air injection device and a tackle sliding stopping mechanism. The intermittent mechanism comprises a gear installed in the middle of the frame, an H-shaped sliding rail fixed to the back portion of the frame, a tackle assembled on the H-shaped sliding rail, and a rack installed on the tackle. The high-pressure air injection device comprises an air gun pressing device and an air gun installed on the tackle. The tackle sliding stopping mechanism comprises a push rod stretching and retracting mechanism and a gripping supporting device installed on the tackle. The mechanical air pressure subsoiler is dragged by the tractor, the ploughing plow sole is broken by injecting high-pressure air in the arable soil deep layer, and the arable soil is subsoiled. The subsoiling effect is good, and energy consumption is reduced.

Description

technical field [0001] The invention belongs to agricultural machinery, in particular to a mechanical air pressure subsoiler. Background technique [0002] Subsoiling the cultivated land can break the bottom layer of the cultivated land to prevent water and soil loss caused by surface runoff, improve the soil structure of the cultivated layer, and form a "soil reservoir", which can effectively improve the utilization rate of precipitation, improve the water storage capacity of the soil, and increase the protection of crops. Water supply. [0003] However, traditional subsoilers, such as shovel subsoilers and vibrating subsoilers, are mainly used in the subsoiling of cultivated land in my country, which not only has poor subsoiling effect, but also consumes a lot of energy. Contents of the invention [0004] The present invention provides a mechanical air pressure subsoiler to solve the technical problems in the above-mentioned background technology. The subsoiler is pulle...
