Description

Technical Field

[0001] The invention relates to a pit digging device, in particular to a portable pit digging device for fruit tree planting. Background Art

[0002] The planting of fruit trees is to prune the growing small fruit trees and then send them to orchards or greenhouses for planting. The root soil at the bottom of the fruit trees should be retained to ensure that the fruit trees can survive after transplanting. At the same time, when planting fruit trees, it is necessary to dig holes in the place where the fruit trees are to be planted in advance.

[0003] The existing fruit tree digging device drives the rotating screw by driving the machinery to bring the soil up from the ground, and at the same time presses the machine down to further deepen the depth. However, the method of pressing the machine down by manpower not only has a high labor intensity, but also makes the digging efficiency low, resulting in slow planting progress. In addition, due to the different environments of the planting areas of some fruit trees, the soil is relatively dry, and direct digging will cause dust to fly, which is not conducive to work. Summary of the invention

[0004] In order to make up for the above shortcomings, the present invention provides a portable pit digging device for fruit tree planting, which aims to improve the situation where manual pressure is required to push the digging machine downward to dig the pit. At the same time, when encountering relatively dry land, the nozzle of the machine can be opened to soak the soil to reduce dust.

[0005] In order to achieve the above object, the present invention provides the following technical solutions: A portable pit digging device for planting fruit trees comprises a base plate, four corners of which are fixedly connected with vertical rods, a top plate is arranged at the top of the vertical rods, a cavity is opened in the middle of the vertical rods, a sliding rod is arranged inside the cavity, a battery compartment, a motor, a water tank and a water pump are fixedly connected to the top of the top plate in sequence, an output end of the motor passes through the top plate and is fixedly connected with a rotating shaft, a blade is arranged on the rotating shaft, a lifting mechanism is arranged between the vertical rods, a nozzle is arranged at the front end of the base plate, a support plate is fixedly connected to the rear end of the base plate, L-shaped rods are arranged on both sides of the top of the support plate, one end of the L-shaped rod is fixedly connected to the support plate, and the other end of the L-shaped rod is fixedly connected to the rear end of the top plate, a double-headed motor is arranged between the L-shaped rods, and a first bevel gear is fixedly connected to the output end of the double-headed motor.

[0006] Through the above technical solution, the overall structure of the machine is adjusted so that the original manual support and pressing operations of the machine are replaced by mechanical devices, reducing the labor intensity of manual labor.

[0007] Furthermore, the lifting mechanism includes a prismatic bracket, and the bottom joints of the two prismatic brackets are rotatably connected to the middle of the left and right sides of the top of the point base plate respectively. A threaded rod is arranged in the middle of the prismatic bracket, and both ends of the threaded rod pass through the prismatic bracket. One end of the threaded rod is fixedly connected to a circular slider, which is slidably connected to the sliding rod, and the other end of the threaded rod is fixedly connected to a second bevel gear.

[0008] Through the above technical solution, the first bevel gear is driven by the double-headed motor to rotate, the first bevel gear will drive the second bevel gear to rotate, and the second bevel gear will rotate the threaded rod, thereby controlling the up and down movement of the lifting frame.

[0009] Furthermore, one end of the vertical rod passing through the bottom plate is rotatably connected to a roller, a hub is provided on the roller, and a push-pull rod is fixedly connected to the top end of the support plate.

[0010] Through the above technical solution, wheels are added to the four corners of the machine to further improve the practicality of the machine. At the same time, the wheels can be used in conjunction with push-pull rods to move the machine, and it can be transported without manual lifting.

[0011] Furthermore, a control switch is provided on the rear side of the battery compartment, and the control switch is electrically connected to the battery compartment, the double-head motor and the water pump.

[0012] Through the above technical solution, the control switch controls the electronic components as a whole, and the control switch integrates all switches, making the overall control more convenient and quick.

[0013] Furthermore, latches are provided at the four corners of the top plate, a sliding groove is provided on the inner side of the vertical rod, and the top plate is slidably connected to the vertical rod.

[0014] Through the above technical solution, pins are provided at the four corners of the top plate, and there are slide grooves on the vertical rods. The top plate can move up and down by inserting the pins into the slide grooves, so that the depth can be adjusted when digging a pit.

[0015] Furthermore, the water pump is connected to the nozzle through a water supply pipe.

[0016] Through the above technical solution, the water pump sends the water in the water tank to the nozzle through the water supply pipe, and the nozzle sprays the water onto the ground to soak the ground and reduce the raising of dust.

[0017] Furthermore, a storage battery is arranged in the battery compartment.

[0018] The present invention has the following beneficial effects: In the present invention, lifting mechanisms are added to both sides of the digging machine, and the transmission of the first bevel gear is driven by a double-headed motor to rotate the second bevel gear. The threaded rod connected to the second bevel gear is rotated to control the lifting frame to rise and fall. The top plate and the machinery on the top plate are adjusted up and down through the rising and falling, and the downward pressing of the mechanical digging pit does not require manual labor, thereby reducing the labor intensity of manual labor.

[0019] In the present invention, a water tank and a water pump are arranged at the front end of the machine, and a nozzle is arranged below the front end of the machine, which are connected through a water supply pipe. When digging holes on some dry ground, dust will be raised, which will reduce the work efficiency. Water is sprayed on the ground to wet the soil and reduce the raising of dust.
