The soil sampler solves the problems that the ridge body structure is easy to damage and the representativeness of the collected soil is poor in the existing soil sampling.
Description
Technical Field
The invention belongs to the technical field of soil sampling equipment, and particularly relates to a soil sampler.
Background
In order to improve the yield and quality of crops, the soil of ridge bodies is often sampled and detected to provide a basis for fertilizing and improving the soil. However, the ridge body is often sampled by means of shovel excavation, T-shaped sampler and the like, but the sampling efficiency is low, the representativeness of the taken soil sample is poor, and the ridge body structure is damaged.
Disclosure of Invention
The invention aims to provide a soil sampler, which solves the problems that the ridge structure is easy to damage and the representativeness of the collected soil is poor in the existing soil sampling.
The technical scheme includes that the soil sampler comprises a cylinder body, wherein a motor is fixedly connected inside the cylinder body, the motor is connected with a closing mechanism, the closing mechanism is connected with a grabber, and handrails are symmetrically arranged on two sides of the top end of the cylinder body.
The present invention is also characterized in that,
the closing mechanism comprises a ball screw, one end of the ball screw is connected with the motor, a moving block is sleeved on the ball screw, two sides of the moving block are respectively and movably connected with a pull rod, and one end, far away from the moving block, of the pull rod is movably connected with a grabber.
The grabber comprises two grabbing bodies which are symmetrically arranged, the two grabbing bodies are movably connected through a rotating shaft, and the two grabbing bodies are semicircular when closed.
The end parts of the two grabbing bodies are provided with cutting edges.
The two sides of the cylinder body are symmetrically provided with strip-shaped grooves which are used for the movement of the pull rod.
The two side walls of one end of the cylinder body close to the grabber are arc-shaped, so that the grabber can be opened.
The other end of the ball screw is provided with a baffle plate.
The invention has the beneficial effects that:
(1) according to the soil sampler, the cutting edge is arranged, so that the resistance between the grabbing body and the soil can be reduced, and quick grabbing is realized;
(2) according to the soil sampler, the motor, the ball screw and the pull rod are arranged to control the closing of the grabber, so that manual control of closing is replaced, manpower is saved, and grabbing efficiency is improved;
(3) the soil sampler provided by the invention can adapt to the structure of the ridge, and can grab from two sides of the ridge to the middle of the ridge, so that the damage to the structure of the ridge is avoided, and the sampling is uniform and representative.

In the figure, 1, a cylinder, 2, a motor, 3, a ball screw, 4, a moving block, 5, a pull rod, 6, a baffle, 7, a grabber, 8, a handrail and 9, a groove are arranged.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The invention relates to a soil sampler, which comprises a cylinder body 1, wherein a motor 2 is fixedly connected inside the cylinder body 1, the motor 2 is connected with a closing mechanism, the closing mechanism is connected with a grabber 7, handrails 8 are symmetrically arranged on two sides of the top end of the cylinder body 1, two side walls of one end of the cylinder body 1 close to the grabber 7 are arc-shaped, so that the grabber 9 can be opened, and a baffle 6 is arranged at the other end of a ball screw 3.
The closing mechanism comprises a ball screw 3, one end of the ball screw 3 is connected with a motor 2, a moving block 4 is sleeved on the ball screw 3, two sides of the moving block 4 are respectively and movably connected with a pull rod 5, one end, far away from the moving block 4, of the pull rod 5 is movably connected with a grabber 7, and the moving block 4 is prevented from sliding down from the ball screw 3 through a baffle 6.
As shown in fig. 2, strip-shaped grooves 9 are symmetrically arranged on two sides of the cylinder 1, and the grooves 9 are used for the vertical movement of the pull rod 5, so as to control the opening and closing of the grabber 7.
The grabber 7 comprises two grabbing bodies which are symmetrically arranged, the two grabbing bodies are movably connected through a rotating shaft, the two grabbing bodies are semicircular when being closed, the two grabbing bodies are movably connected with one ends, far away from the moving block 4, of the pull rods 5 respectively, the two grabbing bodies are provided with cutting edges at the end parts, the cutting edges can reduce grabbing resistance, and grabbing of soil samples is more labor-saving.
The working process of the soil sampler of the invention is as follows: during the use, as shown in fig. 3, motor 2 is opened, then ball 3 rotates and drives movable block 4 upward movement, then pull rod 5 pulling snatchs the body, then snatch the body and open, motor 2 is closed, will snatch the body and place the back on the ridge that needs the sampling, open motor 2 again, make ball 3 reversal drive movable block 4 downward movement, then pull rod 5 promotes and snatchs the body and make and snatch the body closure, then there is soil sample in the grabber, motor 2 is closed, motor 2 is opened again, the lead screw rotates and drives movable block 4 upward movement and drive and snatch the body and open, collect soil sample can.
