Description

Soil sampling device

Technical Field

The utility model relates to a soil testing field, especially a soil sampling device.

Background

Soil sampling is one of the important basic works engaged in scientific and technological work of soil and ecological research, and a soil sampler is a special tool for soil sampling in soil testing, formula fertilization, soil monitoring, farmland soil investigation and quality evaluation projects. When soil is detected, soil samples of different depths are generally required to be detected, a traditional tool can only sample a sample of a certain depth and cannot collect samples of multiple depths at one time, so that great inconvenience is brought to collection work, and meanwhile, because the depths of the samples to be collected are not consistent, an instrument for collecting the samples at fixed intervals cannot be suitable for collecting the soil samples of any depth; there is therefore a need to solve the above problems.

Disclosure of Invention

To the situation, for solving the problem that exists among the prior art, the utility model aims at providing a soil sampling device, can effectively solve the problem of arbitrary degree of depth multilayer soil sample.

The technical scheme for solving the problem is that the sampling device comprises a supporting rod, wherein a plurality of sleeves capable of moving up and down along the supporting rod are sleeved on the supporting rod, a sampler is fixed on the right side surface of each sleeve, a blind hole is formed in the sampler, and the right end of the sampler is pointed; the left vertical pipeline and the right vertical pipeline are arranged on the supporting rod, an upper air bag and a lower air bag are arranged on each pipeline, and a valve is arranged at the upper end of each pipeline; an upper baffle and a lower baffle are inserted on the supporting rod, the baffles are placed in the front-back direction, and the upper baffle and the lower baffle correspond to the upper air bag and the lower air bag.

The utility model discloses can realize the sample of the soil layer of the arbitrary degree of depth of multilayer, sampling speed is fast, and manpower and material resources have been saved to efficient.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1 to 3, the utility model comprises a support rod 1, a plurality of sleeves 2 capable of moving up and down along the support rod 1 are sleeved on the support rod 1, a sampler 3 is fixed on the right side surface of each sleeve 2, a blind hole 4 is arranged in the sampler 3, and the right end of the sampler 3 is pointed; the support rod 1 is provided with a left vertical pipeline 5 and a right vertical pipeline 5, each pipeline 5 is provided with an upper air bag 6 and a lower air bag 6, and the upper end of each pipeline 5 is provided with a valve 7; an upper baffle plate 8 and a lower baffle plate 8 are inserted on the supporting rod 1, the baffle plates 8 are placed in the front-back direction, and the upper baffle plate 8 and the lower baffle plate 8 correspond to the upper air bag 6 and the lower air bag 6 in position.

In order to fix the sleeves 2, a compression bolt 9 is mounted on each sleeve 2.

For better sampling, a plurality of baffles 10 which incline towards the left are inserted on the outer wall of the sampler 3.

In order to adjust the depth of the sampler 3 better, the support rod 1 is provided with scales.

When the utility model is used, firstly, the region where the sample needs to be collected is drilled by using the excavating equipment, so that the device can be arranged in the hole; then, adjusting the height of each sleeve 2 according to the depth of the soil sample to be collected, and screwing a compression bolt 9; then the upper and lower baffle plates 8 are inserted into the support rod 1.

After the device is installed, the whole device is placed in the hole, all the air bags 6 are not inflated before use, the left pipeline 5 is inflated firstly at the moment, the baffle 8 is positioned in the middle of the left air bag 6 and the right air bag 6, so that after the left air bag 6 is inflated, the air bags 6 push the baffle 8 and then push the supporting rod 1 to move rightwards at the moment under the action of the air bags 6, and after the supporting rod 1 moves rightwards at the moment, the samplers 3 installed on the supporting rod 1 all move rightwards and are inserted into the soil layer.

After sampler 3 inserted the inside of soil layer, the soil can enter into sampler 3's inside, because install a plurality of separation blades 10 on the sampler 3, consequently enter into the inside that the soil in the sampler 3 can be better stays in sampler 3.

After the sampler 3 is inserted into the soil layer, the left air bag 6 is deflated at the moment; aerify through the gasbag 6 on right side simultaneously, under the effect of gasbag 6 on right side, whole device can move left, makes sampler 3 break away from the soil layer left, because the effect of separation blade 10, enters into the inside soil sample of sampler 3 and can remain in sampler 3, even soil texture is inseparable, also can remain partly in the inside of sampler 3.

After the sampler 3 is detached from the soil layer, the whole device is taken out, detaching from the pre-drilled hole.

When the soil sample inside the sampler 3 needs to be taken out, the baffle 10 inserted into the sampler 3 is taken out, the baffle 10 does not block the soil, and then the sample inside the sampler 3 can be taken out after the sampler 3 is lightly knocked. After the sample is taken, the entire device may be washed and then the sample may be taken again.

In this device, because the restriction is not established to the quantity of sleeve 2, consequently can set up a plurality of sleeves 2 and sampler 3 as required, once only satisfy the sample of the soil of the arbitrary degree of depth of multilayer, it is simple quick, improved work efficiency, each other do not influence between each sampler 3 simultaneously, can not produce the mixing of sample.

This device adopts gasbag 6 to come left right side drive, realizes inserting and taking out of sampler 3, can be adapted to the sample of the great soil of degree of depth, and the aperture that sets up in advance simultaneously requires for a short time, and the construction is quick.

Go up the cartridge in the sample in this device and have a plurality of separation blades 10, when sampler 3 breaks away from the soil layer, separation blade 10 can block soil, makes soil remain in sampler 3, when taking out the soil in sampler 3, can pull out behind the separation blade 10, pours out fast.
