Description

Technical Field

[0001] This utility model belongs to the field of soil sampling equipment, specifically relating to an orchard soil sampling device. Background Technology

[0002] The heavy metal content in soil is one of the indicators for assessing soil quality, and soil samples need to be tested frequently during fruit cultivation. Soil sampling equipment is required when collecting soil samples from orchards.

[0003] Existing orchard soil sampling devices require opening the sampling tube after sampling, and then using a shovel to remove the soil at the end and the remaining soil. However, soil tends to adhere to the tube wall, making removal and cleaning difficult and affecting sampling efficiency. Therefore, we have proposed an orchard soil sampling device to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that in existing orchard soil sampling devices, soil tends to adhere to the wall of the sampling tube after sampling, making it difficult to remove and clean, which affects the efficiency of the sampling work.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] An orchard soil sampling device includes a frame with handles at both ends, an engine, a connecting rod, and a sampling cylinder. The engine is fixedly mounted on the frame, and the output shaft of the engine passes through the lower end of the frame. The connecting rod is located at the end of the output shaft, and the sampling cylinder is fixedly mounted on the lower end of the connecting rod. The lower part of the connecting rod has a slot that extends into the sampling cylinder, and the connecting rod has a limiting groove that extends horizontally through the slot. An insert rod is movably inserted into the slot, and a push plate is fixedly mounted on the lower end of the insert rod, which is located inside the sampling cylinder. A crossbar is fixedly mounted on the upper end of the insert rod, and the crossbar moves within the limiting groove.

[0007] Further specifying, the sampling cylinder has an opening, and the cylinder wall has a groove at the edge of the opening. An arc-shaped baffle, made of transparent material, is movably installed at the opening. A protrusion matching the groove is fixedly installed at the lower end of the arc-shaped baffle, and a strip groove is formed on the upper part of the arc-shaped baffle. This structural design allows for easy observation of the position of the pushing disk inside the sampling cylinder through the arc-shaped baffle, and facilitates cleaning of the sampling cylinder when the arc-shaped baffle is separated from it.

[0008] Furthermore, a locking sleeve is fitted onto the upper part of the sampling cylinder. When the locking sleeve contacts the upper end of the sampling cylinder, the inner wall of the locking sleeve abuts against the upper part of the arc-shaped baffle. This structural design allows the locking sleeve to move within the upper part of the sampling cylinder, locking the upper part of the arc-shaped baffle and securing it at the opening of the sampling cylinder. It also facilitates the separation of the arc-shaped baffle from the sampling cylinder.

[0009] Furthermore, a compression spring is fitted onto the connecting rod between the locking sleeve and the crossbar. Both ends of the compression spring are fixedly fitted with retaining rings, which respectively abut against the locking sleeve and the crossbar. This structural design, under the elastic force of the compression spring, causes the locking sleeve to abut against the upper end of the sampling cylinder, while the crossbar and insert rod push the pusher to the upper end of the sampling cylinder's inner wall. The structure is simple and easy to use.

[0010] Further specifying, a threaded sleeve is fixedly installed on the upper part of the connecting rod, a threaded disc is threadedly connected to the threaded sleeve, and a force-bearing cylinder is fixedly installed on the lower end of the threaded disc. The force-bearing cylinder is sleeved on the outside of the threaded sleeve, and the lower end of the force-bearing cylinder contacts the crossbar. With this structural design, when the threaded disc moves on the threaded sleeve, it can drive the crossbar to move downward through the force-bearing cylinder, thereby causing the insertion rod and the pushing disc to push the soil inside the sampling cylinder.

[0011] The utility model employing the above technical solution has the following advantages:

[0012] In this invention, when the sampling tube is filled with soil and removed from the soil, the crossbar can drive the insertion rod to move, thereby driving the pushing plate to push the soil in the sampling tube downwards to push the soil out. This can prevent the soil from adhering to the tube wall, which would increase the difficulty of cleaning and soil removal and affect the sampling efficiency. Attached Figure Description

[0027] like Figures 1-6 As shown, the orchard soil sampling device of this utility model includes a frame 1 with handles at both ends, an engine 2, a connecting rod 3, and a sampling cylinder 4. The engine 2 is fixedly installed on the frame 1, and the output shaft of the engine 2 passes through the lower end of the frame 1. The connecting rod 3 is located at the end of the output shaft. The sampling cylinder 4 is fixedly installed at the lower end of the connecting rod 3. A slot is opened at the lower part of the connecting rod 3, which passes through the sampling cylinder 4. A limiting groove 31 is opened on the connecting rod 3, which passes through the slot laterally. An insert rod 32 is movably inserted into the slot. A push plate 33 is fixedly installed at the lower end of the insert rod 32. The push plate 33 is located inside the sampling cylinder 4. A crossbar 34 is fixedly installed at the upper end of the insert rod 32. The crossbar 34 moves within the limiting groove 31.

[0028] The sampling cylinder 4 has an opening, and the cylinder wall of the sampling cylinder 4 has a groove at the edge of the opening. An arc-shaped baffle 41 is movably installed at the opening. The arc-shaped baffle 41 is made of transparent material. A protrusion 42 that matches the groove is fixedly installed at the lower end of the arc-shaped baffle 41. The protrusion 42 can lock the lower end of the arc-shaped baffle 41 by engaging the groove. A strip groove 43 is opened at the upper part of the arc-shaped baffle 41. The arc-shaped baffle 41 can be easily pried open through the strip groove 43 to separate the arc-shaped baffle 41 from the sampling cylinder 4.

[0029] A locking sleeve 44 is fitted on the upper part of the sampling cylinder 4. When the locking sleeve 44 contacts the upper end of the sampling cylinder 4, the inner wall of the locking sleeve 44 abuts against the upper part of the arc-shaped baffle 41. The inner wall of the locking sleeve 44 is provided with an elastic gasket, which can make the arc-shaped baffle 41 fit tightly against the opening.

[0030] A compression spring 5 is sleeved on the connecting rod 3 between the locking sleeve 44 and the crossbar 34. Both ends of the compression spring 5 are fixedly installed with fixing rings 51, and the fixing rings 51 at both ends of the compression spring 5 abut against the locking sleeve 44 and the crossbar 34 respectively.

[0031] A threaded sleeve 6 is fixedly installed on the upper part of the connecting rod 3. A threaded disc 61 is threadedly connected to the threaded sleeve 6. A force-bearing cylinder 62 is fixedly installed on the lower end of the threaded disc 61. The force-bearing cylinder 62 is sleeved on the outside of the threaded sleeve 6, and the lower end of the force-bearing cylinder 62 is in contact with the crossbar 34. The threaded disc 61 moves on the threaded sleeve 6. The crossbar 34 and the insertion rod 32 can be moved by the force-bearing cylinder 62 to drive the pusher disc 33 to push out the soil sample in the sampling tube 4. The position of the pusher disc 33 in the sampling tube 4 can be adjusted, thereby adjusting the soil sampling depth.

[0032] The method of using this utility model is as follows:

[0033] When in use, place the sampling tube 4 end on the ground where the sample is to be taken, the engine 2 works, and the output shaft drives the connecting rod 3 and the sampling tube 4 to rotate, thereby drilling into the soil until the upper end of the sampling tube 4 is close to the soil surface. Apply force to lift the entire sampling device upward through the handle on the frame 1, thereby extracting the sampling tube 4 from the soil.

[0034] When it is necessary to remove the soil from the sampling tube 4, rotate the threaded disc 61, causing the threaded disc 61 to drive the force-bearing cylinder 62 to move downwards. This causes the crossbar 34 to push the insertion rod 32 and the pushing disc 33 to move inside the sampling tube 4 under the limiting action of the limiting groove 31, thereby pushing the soil out of the sampling tube 4. When the soil at the opening of the sampling tube 4 is pushed out, the soil sample can be collected. After the other soil is pushed out, reset the threaded disc 61 and the force-bearing cylinder 62 for subsequent use.

[0035] By manually pushing the locking sleeve 44 upwards, the upper part of the arc-shaped baffle 41 can be disengaged from the sampling cylinder 4, making it easier to clean the inside of the sampling cylinder 4.

[0036] The orchard soil sampling device provided by this utility model has been described in detail above. The specific embodiments are only used to help understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
