Description

Technical Field

[0001] The utility model relates to the technical field of grassland restoration, in particular to a soil sampling device for grassland restoration. Background Technique

[0002] Soil remediation is a technical measure to restore the normal function of polluted soil. In modern society, various pollutants are often generated incidentally when people produce various products, and the most polluted environmental factor is soil. Therefore, in some environmental protection fields, soil remediation is essential. Soil remediation refers to using physical, chemical, and biological methods to transfer, absorb, degrade, and transform pollutants in the soil, reduce their concentration to an acceptable level, or convert toxic and harmful pollutants into harmless substances. During the process of soil remediation, it is necessary to first sample and detect the soil to be remediated.

[0003] Existing soil sampling devices for grassland restoration include a sampling tube, a device box, and a telescopic mechanism. The telescopic mechanism drives the sampling tube to extend out of the device box by telescoping and inserts the sampling tube into the soil to achieve soil sampling. Due to different regional environments, when sampling soil, it is also necessary to sample the soil with the required thickness according to the actual sampling site environment to facilitate the staff's detection of the soil and improve the accuracy of soil detection data. However, the thickness of the soil after sampling by the existing device is consistent, and the sampling thickness cannot be adjusted, resulting in insufficient soil sampling and affecting the accuracy of soil detection data.

[0004] Therefore, in view of the above current situation, there is an urgent need to develop a soil sampling device for grassland restoration to overcome the deficiencies in current practical applications. Content of the Utility Model

[0005] The purpose of the utility model is to provide a soil sampling device for grassland restoration to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution:

[0007] A soil sampling device for grassland restoration includes a device box. One end of the device box is fixed with a handle, and the other end of the device box is movably provided with a sampling tube. A pedal is movably provided on the side wall of the device box, and one side of the pedal is connected to the outer wall of the device box through a spring. It further includes:

[0008] A lifting mechanism, which is fixed in the device box and is fixedly connected to one end of the sampling tube. The lifting mechanism is used to drive the sampling tube to sample the soil.

[0009] A limiting mechanism is provided inside the device box. One end of the limiting mechanism is in movable contact with the lifting mechanism, and the limiting mechanism is used to cooperate with the lifting mechanism to adjust the downward stroke of the sampling tube.

[0010] As a further solution of the present utility model: The lifting mechanism includes a guide seat, a driving member, a first screw rod, a sliding column and a connecting seat. The guide seat is fixed inside the device box. The driving member and the first screw rod are both arranged on the guide seat. The output end of the driving member is connected to the first screw rod. The first screw rod is threadedly connected to the sliding column. One end of the sliding column is slidably arranged on the guide seat. The sliding column passes through the connecting seat and is in contact with the limiting mechanism. And the sliding column is slidably matched with the connecting seat. The connecting seat is fixed on the sampling tube.

[0011] As a further solution of the present utility model: The contact surfaces between the guide seat and the sliding column are all arranged as inclined surfaces.

[0012] As a further solution of the present utility model: The limiting mechanism includes a turning handle, a second screw rod and a limiting seat. The turning handle is fixed at one end of the second screw rod. The other end of the second screw rod extends into the device box. And the second screw rod is threadedly matched with the limiting seat. One end of the limiting seat is slidably installed on the inner wall of the device box. The other end of the limiting seat is in movable contact with the sliding column.

[0013] As a further solution of the present utility model: A discharging seat is also fixed inside the device box. One end of the discharging seat extends into the sampling tube through a guiding groove opened on the side wall of the sampling tube. And one end of the discharging seat is attached to the inner wall of the sampling tube.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] When soil sampling is required, workers align the sampling tube with the sampling area by holding the handle and stepping on the pedal. The driving member drives the first screw rod to rotate. The first screw rod drives the sliding column to slide on the guide seat. Since the contact between the guide seat and the sliding column is an inclined surface, and the sliding column is slidably connected to the connecting seat, the sliding column moves both horizontally and vertically. Due to the limitation of the discharging seat and the device box on the sampling tube, the sliding column can only drive the sampling tube to move vertically, so as to realize the sampling of the soil by the sampling tube.

[0016] When it is necessary to adjust the sampling thickness of the soil, turning the handle drives the second screw rod to rotate, and the second screw rod drives the limit seat to move. The limit seat adjusts the distance between the limit seat and the sliding column by moving, so as to adjust the moving stroke of the sliding column, and further adjust the moving stroke of the sampling tube, so as to realize the adjustment of the sampling thickness of the soil, meet the sampling of the soil in various environments, improve the practicability and working efficiency of the device, and improve the accuracy of soil detection data.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] The technical solutions of the present utility model will be further described in detail below in conjunction with the specific embodiments.

[0024] As Figure 1 and 2 shown, as a soil sampling device for grassland restoration provided in an embodiment of the present utility model, it includes a device box 1, a grip 2 is fixed at one end of the device box 1, a sampling tube 3 is movably arranged at the other end of the device box 1, a pedal 4 is movably arranged on the side wall of the device box 1, one side of the pedal 4 is connected to the outer wall of the device box 1 through a spring 41, and further includes:

[0025] A lifting mechanism 5, the lifting mechanism 5 is fixed in the device box 1, one end of the lifting mechanism 5 is fixedly connected to the sampling tube 3, and the lifting mechanism 5 is used to drive the sampling tube 3 to take soil samples.

[0026] A limiting mechanism 6, the limiting mechanism 6 is arranged in the device box 1, one end of the limiting mechanism 6 is in movable contact with the lifting mechanism 5, and the limiting mechanism 6 is used to cooperate with the lifting mechanism 5 to adjust the downward stroke of the sampling tube 3.

[0027] In this embodiment, the lifting mechanism 5 cooperates with the limiting mechanism 6 to adjust the sampling thickness of the soil, so as to meet the requirement of taking soil samples at different depths in various environments, improve the practicability and working efficiency of the device, and improve the accuracy of soil detection data.

[0028] Such as Figure 1 and 2 As shown, as a preferred embodiment of the present invention, the lifting mechanism 5 includes a guide seat 51, a driving member 52, a first screw 53, a sliding column 54 and a connecting seat 55. The guide seat 51 is fixed in the device box 1, the driving member 52 and the first screw 53 are both arranged on the guide seat 51, the output end of the driving member 52 is connected to the first screw 53, the first screw 53 is threadedly connected to the sliding column 54, one end of the sliding column 54 is slidably arranged on the guide seat 51, the sliding column 54 penetrates through the connecting seat 55 and contacts the limiting mechanism 6, and the sliding column 54 is slidably matched with the connecting seat 55. The connecting seat 55 is fixed on the sampling tube 3.

[0029] Such as Figure 1 and 2 As shown, as a preferred embodiment of the present invention, the contact surfaces between the guide seat 51 and the sliding column 54 are all arranged as inclined surfaces.

[0030] Such as Figure 1 and 2 As shown, as a preferred embodiment of the present invention, the limiting mechanism 6 includes a turning handle 61, a second screw 63 and a limiting seat 63. The turning handle 61 is fixed at one end of the second screw 63, the other end of the second screw 62 extends into the device box 1, and the second screw 62 is threadedly matched with the limiting seat 63. One end of the limiting seat 63 is slidably installed on the inner wall of the device box 1, and the other end of the limiting seat 63 is in movable contact with the sliding column 54.

[0031] In this embodiment, when soil sampling is required, the worker aligns the sampling tube 3 with the sampling area by holding the handle 2 and stepping on the pedal 4. The driving member 52 drives the first screw 53 to rotate, and the first screw 53 drives the sliding column 54 to slide on the guide seat 51. Since the contact between the guide seat 51 and the sliding column 54 is an inclined surface, and the sliding column 54 is slidably connected to the connecting seat 55, the sliding column 54 moves both horizontally and vertically. Due to the limitation of the unloading seat 7 and the device box 1 on the sampling tube 3, the sliding column 54 can only drive the sampling tube 3 to move vertically, thereby realizing the sampling of the soil by the sampling tube 3;

[0032] When the sampling thickness of the soil needs to be adjusted, the turning handle 61 drives the second screw 62 to rotate, and the second screw 62 drives the limit seat 63 to move. The limit seat 63 adjusts the distance between the limit seat 63 and the sliding column 54 by moving, thereby adjusting the moving stroke of the sliding column 54, and further adjusting the moving stroke of the sampling tube 3, so as to realize the adjustment of the sampling thickness of the soil, meet the sampling of soils with different depths in various environments, improve the practicability and working efficiency of the device, and improve the accuracy of soil detection data.

[0033] In a preferred embodiment, the driving member 52 is preferably a servo motor.

[0034] As Figure 3 and 4 shown, as a preferred embodiment of the present invention, a discharge seat 7 is further fixed in the device box 1. One end of the discharge seat 7 extends into the sampling tube 3 through a guide groove 31 opened on the side wall of the sampling tube 3, and one end of the discharge seat 7 is in contact with the inner wall of the sampling tube 3.

[0035] In this embodiment, when the sampling tube 3 descends to the sampling depth, due to the setting of the guide groove 31, the sampling tube 3 does not cut off the sampled soil. At this time, the worker rotates the device box 1 and the sampling tube 3 through the handle 2, so as to realize the cutting of the sampled soil by the sampling tube 3, so that when the sampling tube 3 moves upward, the sampled soil is still in the sampling tube 3. When the sampling tube 3 moves upward to a certain height and continues to move upward, the discharge seat 7 limits the sampled soil and pushes the sampled soil out of the sampling tube 3, which is convenient for the worker to collect it and also convenient for the device to carry out the next stage of sampling work, improving the practicability and working efficiency of the device.

[0036] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
