[0001] The utility model relates to the technical field of sweet potato planting, in particular to a sweet potato planting seedling combing and dividing device. Background Technique

[0002] Sweet potato, also known as sweet potato, is a twining herbaceous vine of the genus Dioscorea in the Convolvulaceae family. The underground tuber branches at the top and the end bulges into an ovoid tuber. The outer skin is light yellow and smooth. The stem twines counterclockwise, with thorns at the base and is covered with T-shaped pubescence. The leaves are alternate, broadly heart-shaped; the male inflorescence is a spike inflorescence, solitary. The male flowers have no pedicels or very short pedicels; the bracts are ovate, with a gradually pointed apex; the perianth is shallow cup-shaped and covered with short pubescence; the capsule is triangular prism-shaped, slightly concave at the top, truncate at the base, and each edge is wing-shaped; the seeds are round and have wings. The flowering period is in early summer.

[0003] At present, in order to prevent the plants of sweet potatoes from growing excessively, people usually prune the branches manually. When pruning sweet potato seedlings, it is necessary to start pruning from 1-2 nodes close to the seedbed, so that each branch has about 7 stem nodes, so as to prevent the germs on the seedbed from being brought onto the sweet potato seedlings. However, since ordinary scissors are generally used for pruning, especially when pruning these seedlings, this type of scissors is very easy to cause hand fatigue after long-term use. At the same time, since there is no protection at the top of the scissors, it is also very easy to hurt people. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a sweet potato planting seedling combing and dividing device, which has the advantages of labor saving and strong safety, and solves the problems of easy hand fatigue and poor safety caused by long-term use of traditional scissors.

[0005] To achieve the above-mentioned purposes of labor saving and strong safety, the utility model provides the following technical solution: a sweet potato planting seedling combing and dividing device, including a pruning box, sliding components are arranged on both inner walls of the pruning box, a pruning mechanism is arranged on the sliding components, and two retaining pins are fixedly installed on the right inner wall of the pruning box;

[0006] The pruning mechanism includes an assembly block. The outer parts of both retaining pins are clamped with the assembly blocks. Pruning blades are fixedly installed on the left sides of both assembly blocks. Pressure handles extending to the outside of the pruning box are fixedly installed on the separating ends of both assembly blocks. Sliders are fixedly installed inside both assembly blocks. A sliding rod is slidably connected inside both sliders. Two limit blocks are fixedly installed on the outer part of the sliding rod. Two groups of return springs are arranged between both assembly blocks.

[0007] Furthermore, the sliding assembly includes a slide box, and two slide boxes are fixedly installed on the front and rear inner walls of the trimming box. The inner walls of the slide box are slidably connected to pulleys, and a rotating rod is fixedly connected between the two front pulleys and the two rear pulleys. The outer surfaces of the two rotating rods are fixedly connected to bearings, and the outer surfaces of the two bearings are fixedly connected to connecting blocks.

[0008] Furthermore, the opposite surfaces of the two connecting blocks are fixedly connected to the upper and lower ends of the sliding rod.

[0009] Furthermore, both upper and lower ends of the trimming box are provided with long sliding grooves adapted to the two pressure handles.

[0010] Furthermore, an extension slot adapted to fit the two trimming blades is provided on the left side of the trimming box.

[0011] Furthermore, the right sides of the two assembly blocks are each provided with a clamping hole adapted to two clamping pins, the two clamping pins are made of magnets, and the inner walls of the two clamping holes are fixedly connected with iron sheets.

[0012] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0013] 1. The sweet potato seedling combing and dividing equipment is provided with a pruning mechanism.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. 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.

[0022] Please refer to Figures 1-5 , a sweet potato planting seedling combing and dividing device in this embodiment, including a pruning box 1, sliding assemblies 2 are arranged on the inner walls on both sides of the pruning box 1, a pruning mechanism 3 is arranged on the sliding assemblies 2, and two retaining pins 4 are fixedly installed on the inner wall on the right side of the pruning box 1;

[0023] The pruning mechanism 3 includes an assembly block 301. The outer parts of the two retaining pins 4 are both clamped with the assembly block 301. Pruning blades 302 are fixedly installed on the left sides of the two assembly blocks 301. Pressure handles 303 extending to the outside of the pruning box 1 are fixedly installed at the separated ends of the two assembly blocks 301. Sliders 304 are fixedly installed inside the two assembly blocks 301. A sliding rod 305 is slidably connected inside the two sliders 304. By pressing the pressure handles 303 at the upper and lower ends, the handles will drive the sliders 304 inside the assembly block 301 to move on the sliding rod 305 after being stressed. At the same time, the pruning blade 302 on the left side can also move along with the assembly block 301. By merging the sharp ends of the two pruning blades 302 with each other, an object can be quickly pruned and divided. Two limit blocks 306 are fixedly installed on the outer part of the sliding rod 305. Two groups of return springs 307 are arranged between the two assembly blocks 301. After pruning is completed, only need to gently release the two handles, and the two handles can quickly separate the two assembly blocks 301 and the two pruning blades 302 through the restoring characteristics of the two return springs 307. At the same time, the two limit blocks 306 can prevent the force of the return spring 307 from being too large and causing the slider 304 to slide out of the sliding rod 305. Therefore, this device is both simple to operate and time-saving and labor-saving during the pruning process.

[0024] In the implementation of the case, the sliding component 2 includes a chute box 201. Two chute boxes 201 are fixedly installed on the inner walls of the front and rear sides of the trimming box 1. A pulley 202 is slidably connected to the inner wall of the chute box 201. A rotating rod 203 is fixedly connected between the two front pulleys 202 and the two rear pulleys 202. Bearings 204 are fixedly connected to the outer surfaces of the two rotating rods 203. Connecting blocks 205 are fixedly connected to the outer surfaces of the two bearings 204. The opposite surfaces of the two connecting blocks 205 are fixedly connected to the upper and lower ends of the sliding rod 305. Thus, with the assistance of the sliding component 2, the trimming mechanism 3 can move left and right within the trimming box 1.

[0025] In the implementation of the case, long chute grooves adapted to the two pressure handles 303 are provided at both the upper and lower ends of the trimming box 1, enabling the two pressure handles 303 to freely control the movement of the cutting mechanism 3 with the assistance of the sliding component 2. An extension groove adapted to the two trimming blades 302 is provided on the outer side of the left side of the trimming box 1, allowing the two trimming blades 302 to be exposed outside the trimming box 1, facilitating subsequent trimming work.

[0026] In the implementation of the case, card holes adapted to the two pins 4 are provided on the right sides of the two assembly blocks 301. The two pins 4 are made of magnets, and iron sheets are fixedly connected to the inner walls of the two card holes. When the trimming mechanism 3 is inside the trimming box 1, the two pins 4 can tightly adsorb the trimming mechanism 3, effectively preventing accidents and greatly enhancing its safety.

[0027] During implementation, the operations are carried out in the following steps:

[0028] 1) First, push the two pressure handles 303;

[0029] 2) Then, with the assistance of the sliding component 2, expose the two trimming blades 302 outside the trimming box 1;

[0030] 3) Then, press the pressure handles 303 at the upper and lower ends;

[0031] 4) Finally, perform rapid trimming and splitting by merging the sharp ends of the two trimming blades 302 with each other.

[0032] In summary, the sweet potato seedling combing and dividing device is provided with a trimming mechanism 3. By pressing the pressure handles 303 at the upper and lower ends, the handles will drive the slider 304 inside the assembly block 301 to move on the slide rod 305 after being subjected to force. At the same time, the trimming blade 302 on the left side can also move with the assembly block 301. By merging the sharp ends of the two trimming blades 302 with each other, the object can be quickly trimmed and divided. After trimming is completed, it is only necessary to gently release the two handles. The two handles can quickly separate the two assembly blocks 301 from the two trimming blades 302 through the restoration characteristics of the two return springs 307. At the same time, the two limit blocks 306 can prevent the restoration force of the return spring 307 from being too large, causing the slider 304 to slide off the slide rod 305. Therefore, the device is easy to operate and saves time and effort during the trimming process, solving the problem that long-term use of this type of scissors easily leads to hand fatigue.

[0033] Moreover, by providing the sliding assembly 2, the latch 4 and the trimming box 1, it can be ensured that when the trimming mechanism 3 is not needed, the trimming mechanism 3 can stay inside the trimming box 1 honestly, which can effectively prevent accidents, greatly enhance its safety, and solve the problem that the top of the scissors has no protection and is easy to hurt people.
