Description

Technical Field

[0001] The present application relates to the technical field of soil extractors, and in particular to a soil extractor with a pedal. Background Art

[0002] A soil sampler, also known as a soil sampler, is a tool used to obtain soil samples. Commonly used ones include soil drills, spades and shovels. A soil drill consists of a drill bit and a handle made of hard material (steel or hard plastic). The drill bit is usually spiral or cylindrical. The top of the spiral drill bit is a pair of sharp blades that can be rotated to cut into the soil. Immediately following the blade is an expanded cavity for holding soil. As the handle rotates, it drills down into the soil surface, and the soil sample of the soil layer to be collected can be introduced into the cavity.

[0003] In the current soil sampling work, especially in the environment with hard soil and more gravel, the sampling process often becomes extremely difficult. When facing such an environment, the traditional soil sampler needs to expend a lot of physical strength and is inefficient. The Chinese patent (Announcement No.: CN209387321U) discloses a pedal resistance type convenient soil sampler. By installing a pedal rod, the operator can apply greater downward pressure by stepping on the lever to assist the drill bit to drill into the soil. This design significantly reduces the demand for hand strength and makes the sampling process easier, but the pedal rod in the above document is fixed on the vertical pole, and the pedal rod is inconvenient to flip up and down, which makes the soil sampler inconvenient to carry.

When the fixing blocks 12 are fixed in the storage holes, the handles 11 can be vertically fixed to the two sides of the grip 1, so that the area for storing and placing the soil extractor can be further reduced.

[0033] See also Figures 1 to 3 The flip assembly in this embodiment includes two round blocks 51, two connecting blocks 52, two connecting plates 53, and a limiting structure fixedly installed inside the two connecting plates 53.

[0034] Among them, two rotating grooves are opened on the opposite sides of the two connecting blocks 52, and the round blocks 51 are rotatably connected to the inside of the rotating grooves, and the two round blocks 51 are respectively fixed to the front and rear walls of the fixed plate 4, and the two connecting blocks 52 are fixed to the left side wall of the foot pedal 5, so that the round blocks 51 are located in the rotating grooves, so that the fixed plate 4 and the foot pedal 5 can be rotatably connected, and the foot pedal 5 can be flipped up and down at the right end of the fixed plate 4.

[0035] See also Figure 3 The limiting structure in this embodiment includes two moving blocks 55, two sets of sleeve rods 56, two limiting blocks 54 fixedly installed on the opposite sides of the two moving blocks 55, a pull rope 58 fixedly installed on the opposite sides of the two moving blocks 55, and a pull block 59 fixedly installed on the other end of the pull rope 58. A spring 57 is sleeved on the outside of the sleeve rod 56, and a vertical stick 510 is abutted on the inner side of the pull rope 58. The vertical stick 510 is rotatably connected to the upper two walls of the inner cavity of the connecting plate 53 through bearings, so as to guide the pull rope 58 so that the pull rope 58 can be in an L shape.

[0036] Secondly, four limiting holes are provided on the opposite sides of the two round blocks 51, and the limiting blocks 54 are inserted into the inner sides of the limiting holes. When the limiting blocks 54 are located in the limiting holes, the round blocks 51 can be fixed in the rotating groove so as to limit the direction of the foot pedal 5, and four through holes are provided on the opposite sides of the two connecting blocks 52, and two connecting holes are provided on the opposite sides of the two connecting plates 53. The limiting blocks 54 are slidably connected to the connecting holes and the inner sides of the through holes, so that the limiting blocks 54 can be moved from the connecting plates 53 to the limiting holes of the round blocks 51.

[0037] In addition, four sleeve holes are opened on the opposite sides of the two shift blocks 55, and the sleeve rods 56 are slidably connected to the inside of the sleeve holes, and the two groups of sleeve rods 56 are respectively fixed to the opposite side of the inner cavity of the two connecting plates 53, so that the sleeve rods 56 can move into the interior of the shift block 55 through the sleeve holes.

[0038] In addition, a sliding hole is provided on the opposite side of the front and rear connecting plates 53, and the pull block 59 is slidably connected to the inner side of the sliding hole so that the pull block 59 can pass through the connecting plate 53, and a transverse groove is provided on the opposite wall of the inner cavity of the two connecting plates 53, and the pull block 59 is slidably connected to the inside of the transverse groove so that the pull block 59 can be stably located in the connecting plate 53.

[0039] See also Figure 1 and Figure 4 The disassembly assembly in this embodiment includes an insert block 31, two insert tubes 32, two sleeves 33, and an insert rod 34 fixedly mounted on the inner wall of the sleeve 33. The insert tube 32 is threadedly connected to the inside of the sleeve 33.

[0040] Furthermore, the insert block 31 is fixed to the top of the soil drilling bit 2 , and the connecting tube 3 is in a cylindrical shape with a hollow interior and a missing lower end, so that the insert block 31 can be inserted into the connecting tube 3 .

[0041] At the same time, two circular holes are provided at both ends of the connecting tube 3. The insert tube 32 is a cylinder with a hollow interior and missing left and right ends.

[0043] The working principle of the above embodiment is:

[0044] When in use, when the footrest 5 needs to be stored, the two pull blocks 59 move to the right, so that the pull block 59 pulls the drawstring 58 to move, so that the two drawstrings 58 can pull the front and rear moving blocks 55 to move in opposite directions, so that the sleeve rod 56 gradually moves into the moving block 55, and the moving block 55 can squeeze the spring 57, so that the moving block 55 can drive the limit block 54 to move out of the two horizontal limit holes of the round block 51 and retract into the connecting plate 53, so that the footrest 5 can be turned upward, and the pull block 59 can be loosened, so that the drawstring 58 is no longer subjected to tension, and the spring 57 is no longer subjected to pressure compression, so that the spring 57 can push the limit block 54 to move into the two vertical limit holes of the round block 51 through the moving block 55, so that the turned footrest 5 can be positioned and fixed, so that the footrest 5 is easy to turn up and down, and it is easy to fold and store it;

[0045] When the soil drill bit 2 needs to be disassembled, the sleeve 33 is rotated to make the sleeve 33 and the insert sleeve 32 threadedly connected. When the insert sleeve 32 is gradually exposed to the outside, the insert rod 34 can be moved out of the mounting hole of the insert block 31 and can be moved out of the connecting tube 3 and the insert sleeve 32, so that the insert rod 34 can be pulled out of the connecting tube 3, and the above steps are repeated to operate the sleeve 33 on the other side so that the insert block 31 can fall off from the connecting tube 3, thereby facilitating the disassembly and replacement of the soil drill bit 2.
