Description

Technical field:

[0001] The utility model relates to the technical field of garlic sowing, in particular to a fast lifting depth regulating device for a hand-held garlic sowing machine. Background technology:

[0002] The hand-held garlic planter is a semi-mechanized garlic planting equipment. It still has a good market because of its low price and relatively simple operation. In order to better sow garlic, the existing hand-held garlic planter has a sinking depth adjustment function. The existing sinking depth adjustment is mainly adjusted by bolts or screw nuts. For example, a small hand-held self-propelled garlic planter disclosed in a Chinese patent (authorization announcement number: CN110476554B) has solved the technical problem of sinking depth adjustment in the prior art, but there are still deep technical problems in practical applications. Among them, the more prominent one is that when the hand-held garlic planter turns around at the head of the field, it needs to be lifted. However, since the prior art generally uses bolts or screw nuts for adjustment, it requires complicated operations to remove the bolts or adjust the screw when lifting it to achieve turning around without lifting the sinking wheel, which seriously affects the sowing efficiency. Sometimes, in order not to affect the sowing efficiency, many operators directly lift the sinking wheel together to turn around, which consumes a lot of physical strength. Therefore, it is necessary to improve and optimize on the basis of the existing sinking depth adjustment, so as to achieve rapid lifting and lowering to facilitate turning around under the premise of sinking depth adjustment.

[0003] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility model content:

[0024] In addition, terms such as "upper end" and "lower end" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the position of the indicated technical features.

[0025] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "coupling", "fixing" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral body; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] As shown Figures 1-4 in the figure, a quick lifting and depth adjustment device for a walking garlic planter includes a frame 1, where the frame 1 is an existing component on the walking garlic planter 24. On both sides of the frame 1, outer cylinders 2 are vertically provided. An inner cylinder 3 is sleeved inside the outer cylinder 2. The lower end of the inner cylinder 3 is arranged on a depth wheel support 4. A depth wheel 5 is rotatably arranged between the two depth wheel supports 4. A nut 6 is arranged on the inner cylinder 3. For the convenience of installation, the nut 6 is usually arranged at the upper end of the inner cylinder 3. A handle screw rod 7 is arranged on the nut 6. A limiting part 8 is arranged on the handle screw rod 7. A limiting plate 9 is arranged at the upper end of the corresponding outer cylinder 2. A through hole 10 for the handle screw rod 7 to pass through is arranged on the limiting plate 9. A support 11 is arranged on the side wall of the outer cylinder 2. A return spring 12 and a wire rope 13 are arranged on the support 11. The front end of the wire rope 13 passes through the return spring 12 and is connected with a bolt 14. An outer insertion hole 15 is arranged on the side wall of the outer cylinder 2. A plurality of inner insertion holes 16 are vertically arranged at intervals on the side wall of the inner cylinder 3. The bolt 14 passes through the outer insertion hole 15 and is inserted into one of the inner insertion holes 16. The rear end of the wire rope 13 is connected with a control lever 17. A handrail 23 is arranged on the frame 1. The control lever 17 is arranged on the handrail 23. By adopting the structure of the nut 6, the handle screw rod 7 and the cooperation of the limiting part 8 and the limiting plate 9, it can not only meet the depth adjustment but also realize the separation of the outer cylinder 3 and the inner cylinder 2, providing the possibility for subsequent quick separation and connection. By designing the structure of the bolt 14, the return spring 12, the wire rope 13, the outer insertion hole 15 and the inner insertion hole 16, the connection and separation of the outer cylinder 2 and the inner cylinder 3 can be quickly realized by using the bolt, so as to meet the requirements of sowing and turning around.

[0027] The outer cylinder 2 and the inner cylinder 3 adopt a square tube structure, and the outer cylinder 2 is welded on the frame 1. The square tube structure has the advantages of low cost and high structural strength.

[0028] The handle screw rod 7 includes a threaded section 701, a smooth shaft section 702 and a handle 703 arranged in sequence from bottom to top. The threaded section 701 is in threaded connection with the nut 6, and the limiting part 8 is arranged on the smooth shaft section 702. This structural design can realize the depth adjustment by thread and can also be separated.

[0029] The limiting part 8 is a limiting block or a limiting bearing fixed on the smooth shaft section 702.

[0030] The wire rope 13 includes a steel wire rope 1301. A wire tube 1302 is wrapped on the outer wall of the steel wire rope 1301. The front end of the steel wire rope 1301 passes through the return spring 12 and is connected with the bolt 14. A baffle 18 is arranged between the bolt 14 and the return spring 12. The return spring 12 can ensure that the bolt 14 always has an outward force, so that when the frame 1 is lowered, the bolt 14 can be automatically inserted into the inner insertion hole 16, and then smoothly enter the sowing state.

[0031] The front end of the bolt 12 is arranged in a conical shape 22, which facilitates the quick insertion of the bolt 12 into the inner jack 16.

[0032] A control lever 17 is rotatably arranged on the handrail 23. An active cable 19 is connected to the control lever 17. The active cable 19 is connected to a cable distribution box 20. The two cables 13 are respectively connected to the cable distribution box 20. Here, the cable distribution box 20 realizes synchronously pulling the two cables 13 with one active cable 19. The cable distribution box 20 belongs to the prior art and can be directly purchased. Its internal structure is relatively simple, including a joint bracket slidably arranged vertically. An upper joint is arranged at the upper end of the joint bracket, and two lower joints are arranged at the lower end. The upper joint is connected to the active cable 19, and the two lower joints are respectively connected to a cable 13, so that one active cable 19 can synchronously pull the two cables 13.

[0033] A locking handle 21 is arranged on the front side wall of the outer cylinder 2. The locking handle 21 assists in connecting and locking the inner cylinder and the outer cylinder.

[0034] Instructions for use:

[0035] During sowing, the bolt 14 is inserted into the inner jack 16, and the outer cylinder 2 and the inner cylinder 3 are connected together.

[0036] When turning around, the cable 13 is pulled by operating the control lever 17. The cable 13 pulls the bolt 14 out of the inner jack 16, and then the handrail 23 (driving the frame 1 to move together) is lifted to achieve separation. At this time, turning around is relatively easy to operate. After turning around is completed, the handrail 23 is pressed down. Under the action of the return spring 12, the bolt 14 always has an outward extending movement. When the bolt 14 corresponds to the inner jack 16 during the process of the handrail 23 descending, it is quickly inserted, thereby realizing the connection.

[0037] The above specific implementation manners cannot be used as a limitation to the protection scope of the present invention. For those skilled in the art of this technology, any alternative improvement or transformation made to the implementation manner of the present invention falls within the protection scope of the present invention.

[0038] Those parts not detailed in the present invention are all well-known technologies to those skilled in the art of this technology.
