Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of vegetable grafting, especially to a vegetable grafting device capable of preventing excessive cutting. BACKGROUND

[0002] The vegetable cutting grafting device is a key tool in modern agriculture, and its function is to cut the grafting part of the vegetable. Through the cutting assembly, the staff can quickly and accurately complete the cutting operation of the stock and the scion, creating an ideal contact surface for grafting.

[0003] The existing vegetable grafting device faces a practical problem during operation. The design often only includes one cutting blade, which means that once the cutting blade is damaged or worn out, it must be replaced immediately to maintain uninterrupted grafting operations. This design can easily hinder the grafting process because replacing the blade often requires interrupting the operation, which can affect work efficiency and progress. Therefore, the current vegetable grafting device generally lacks an effective backup blade mechanism to quickly switch in case of blade damage, ensuring that grafting operations can continue seamlessly.

[0006] In at least some embodiments,

[0007] The limiting ring is located below the limited ring; and a locking bolt is threadedly installed on one side of the limiting ring.

[0008] In at least some embodiments,

[0009] The inner bottom end of the main body is slidably installed with a sliding piece; and the top of the sliding piece is fixedly connected with the bottom end of the pressing rod.

[0010] In at least some embodiments,

[0011] The inner rotating installation of the sliding piece is provided with a rotating shaft; and a clamping groove is formed in the circumferential outer wall of the rotating shaft.

[0012] In at least some embodiments,

[0013] The front side of the sliding piece is provided with a sliding groove; and the part of the rotating shaft provided with the clamping groove is also located inside the sliding groove.

[0014] In at least some embodiments,

[0015] The inner sliding installation of the sliding groove is provided with a clamping block; the clamping block is in a T-shaped structure; and one end of a restoring spring B is embeddedly installed in the top of the clamping block.

[0016] In at least some embodiments,

[0017] The other end of the restoring spring B is embeddedly installed in the top of the sliding groove; a switching piece is fixedly installed on the rotating shaft; and a cutting blade is fixedly installed on the switching piece.

[0018] The utility model provides a kind of overcutting-preventing vegetable grafting device, with following beneficial effects:

[0019] 1. By setting switching piece, and being equipped with a cutting blade in each end thereof, this design ensures that during use, once a cutting blade is damaged, only needs to rotate switching piece simply, another standby cutting blade can be quickly enabled, so that the grafting operation is effectively avoided long time interruption due to replacement blade, ensure the smooth progress of vegetable grafting work.

[0020] 2. By introducing the combined design of limiting ring and limited ring, the cutting depth of limited ring, pressing rod and cutting blade in the descending process is accurately controlled using the height setting of limiting ring, ensure that this depth is strictly limited in the space range between limiting ring and limited ring, so that the accurate limitation of cutting depth is realized, the overcutting condition is effectively prevented, the fault tolerance of vegetable grafting operation is significantly improved, and the high quality and stability of operation are ensured.

[0032] In order to make the technical scheme of the embodiments of the present application clearer, the drawings of the embodiments will be briefly introduced below.

[0033] Please refer to Figures 1 to 6 : Embodiment one

[0034] The utility model provides a kind of overcutting-preventing vegetable grafting device, comprising: main body 1, the inside top of main body 1 is provided with mounting groove 2;Pressing rod 3 is slidably installed in the inside of mounting groove 2;Pressing rod 3 is fixedly installed on the circumferential outer wall of embedding disc 4;Embedding disc 4 is disc-shaped structure;Embedding disc 4 is also slidably installed in the inside of mounting groove 2;One end of restoring spring A 5 is embedded and installed in the bottom of embedding disc 4;The other end of restoring spring A 5 is embedded and installed in the bottom of mounting groove 2;Limited ring 6 is slidably installed on the outer wall of main body 1;Limited ring 6 is circular structure;Limited ring 6 is also fixedly connected with embedding disc 4;Limiting ring 7 is also slidably installed on the circumferential outer wall of main body 1, by setting switching piece 15, and one cutting blade 16 is set in the both ends of switching piece 15, so that after the damage of one cutting blade 16 in the use process, another cutting blade 16 can be quickly replaced and used by rotating switching piece 15, so the design will not cause grafting work to be hindered for a long time due to the replacement of cutting blade 16, and the normal progress of vegetable grafting work is avoided due to the replacement of cutting blade 16 for too long.

[0035] In example two, on the basis of example one, limiting ring 7 is located below limited ring 6;Locking bolt 8 is threadedly installed on one side of limiting ring 7;Sliding piece 9 is slidably installed in the inside bottom of main body 1;The top of sliding piece 9 is fixedly connected with the bottom end of pressing rod 3;Rotating shaft 10 is rotatably installed in the inside of sliding piece 9;Rotating shaft 10 is provided with clamping groove 11 on the circumferential outer wall;By setting limiting ring 7 and limited ring 6, the height of limiting ring 7 is limited, so that the cutting depth of limited ring 6, pressing rod 3 and cutting blade 16 can only reach the height between limiting ring 7 and limited ring 6, the cutting depth is limited, the situation of excessive cutting is avoided, and the fault tolerance of the vegetable grafting work is improved.

[0036] In example three, on the basis of example two, sliding groove 12 is formed in the front side of sliding piece 9;The part of rotating shaft 10 provided with clamping groove 11 is also located in the inside of sliding groove 12;Clamping block 13 is slidably installed in the inside of sliding groove 12;Clamping block 13 is T-shaped structure;One end of restoring spring B 14 is embedded and installed in the top of clamping block 13;The other end of restoring spring B 14 is embedded and installed in the top of sliding groove 12;Switching piece 15 is fixedly installed on rotating shaft 10;Cutting blade 16 is fixedly installed on switching piece 15;Since there are four clamping grooves 11, the state of cutting blade 16 can also be switched to horizontal state, so that cutting blade 16 and main body 1 can form an axe-shaped structure, the operation mode of the grafting device is changed, and the needs of more staff are met.
