Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a grape thinning machine. Background Technology

[0002] As the grape industry continues to develop, the market's demands for grape yield and quality are increasing. High-quality grapes require proper fruit thinning to ensure uniform fruit size, good color, and sufficient sugar content. Traditional manual fruit thinning is inefficient and cannot meet the needs of large-scale vineyards. Moreover, manual fruit thinning has obvious drawbacks: it is labor-intensive, requiring a large amount of manpower and time, making it difficult to complete the thinning quickly and ensuring that the grapes are thinned properly during their optimal growth stage. In addition, the accuracy is greatly affected by human factors, such as differences in the skill levels of different thinners, leading to inconsistent thinning results. Utility Model Content

[0003] The purpose of this invention is to provide a grape thinning machine that can effectively solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A grape thinning machine includes two outer shells, each with a rotating handle. The rotating handles on the two outer shells are arranged crosswise and connected by a first positioning shaft. An inner shell is located inside each outer shell and connected to the outer shell by a second positioning shaft. A row of fruit rollers is distributed at the opening of the inner shell. Multiple fruit protrusions are arranged in a circular array on the outer wall of each fruit roller. After pressing the two rotating handles to bring the fruit rollers in the two inner shells closer together and clamp the bunch of grapes, a drive assembly drives the fruit rollers in the two inner shells to rotate simultaneously to thin the bunch of grapes. The outer wall of each outer shell has a first protrusion and a second protrusion located on both sides of the second positioning shaft. The first and second protrusions are respectively threaded to a first adjusting stud and a second adjusting stud.

[0006] Preferably, the drive assembly includes a drive motor and a transmission belt, the fruit and vegetable roller is mounted on a drive shaft, one end of the drive shaft is provided with a drive wheel, the output end of the drive motor is equipped with a drive wheel, and the drive wheel is connected to the drive wheel through the transmission belt.

[0007] Preferably, a return spring is provided between the two rotary handles. The return spring and the vegetable and fruit machine housing are respectively located on both sides of the first positioning shaft. Under the action of external force, the two rotary handles move closer to each other and cause the return spring to contract. The extension of the return spring causes the two rotary handles to open.

[0008] Preferably, a fixing stud is provided on one of the rotating handles facing the other rotating handle, and an adjusting sleeve is threadedly connected to the fixing stud.

[0009] Preferably, the cross-section of the adjusting screw sleeve is a regular polygonal structure.

[0010] Preferably, both of the rotating handles are provided with positioning bosses, and a positioning ring is rotatably installed on the positioning boss of one of the rotating handles. When the two rotating handles approach each other until the positioning bosses on the two rotating handles abut against each other, the positioning ring is snapped onto the other rotating handle.

[0011] Preferably, the outer wall of the vegetable and fruit roller has four vegetable and fruit protrusions arranged in a circular array.

[0012] Preferably, each of the two vegetable and fruit machine housings has an outlet slot on its rear side.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When processing grapes, simply place the two rows of fruit-removing rollers from the two outer casings of the fruit-removing machine on either side of the bunch of grapes. Manually press the two rotating handles to make the two rows of fruit-removing rollers rotate around the first positioning axis with the two outer casings until the bunch of grapes is clamped between the two rows of fruit-removing rollers. Then, the drive motor starts working and drives the two rows of fruit-removing rollers to rotate simultaneously through the drive wheel, transmission belt, and transmission wheel. This causes the fruit-removing protrusions on the two rows of fruit-removing rollers to rotate, and the corresponding fruit-removing protrusions on the two rows of fruit-removing rollers to remove the grapes. The fallen grapes pass through the opening slot at the rear end of the inner casing of the fruit-removing machine. The outlet groove on the outer shell of the fruit and vegetable machine is emptied; the size of the openings of the two inner shells of the fruit and vegetable machine can be adjusted according to the size of the bunch of grapes. First, loosen the first adjusting stud, then tighten the second adjusting stud so that the second adjusting stud pushes the front opening of the inner shell of the fruit and vegetable machine closer to each other, while the front openings of the two rows of fruit and vegetable rollers become smaller; similarly, first loosen the second adjusting stud, then tighten the first adjusting stud so that the first adjusting stud pushes the rear opening of the inner shell of the fruit and vegetable machine closer to each other and the front openings of the two inner shells of the fruit and vegetable machine move away from each other, while the front openings of the two rows of fruit and vegetable rollers become larger.

[0015] By adjusting the position of the adjusting sleeve on the fixed stud, the distance between the adjusting sleeve and the other rotating handle is adjusted. When the two rotating handles are manually pressed to rotate around the first positioning axis, when the adjusting sleeve and the other rotating handle abut against each other, the opening of the two rows of vegetable and fruit rollers inside the two vegetable and fruit machine shells reaches its minimum, thereby limiting the minimum included angle between the two vegetable and fruit machine shells. After the grape thinning work is completed, the two rotating handles are brought close together until the positioning bosses on the two rotating handles abut against each other. The return spring is then compressed, and the positioning ring is then snapped onto the other rotating handle. Under the action of the return spring, the other rotating handle is tensioned on the positioning ring, which facilitates the storage and handling of this utility model. This utility model improves the working efficiency of grape thinning. Attached Figure Description

[0023] Please see Figure 1-5As shown, a grape thinning machine includes two outer shells 1, each with a rotating handle 2. The rotating handles 2 on the two outer shells 1 are arranged crosswise and connected by a first positioning shaft 3. An inner shell 4 is provided inside the outer shell 1, and the outer shells 1 and the inner shells 4 are connected by a second positioning shaft 5. A row of fruit rollers 6 is distributed at the opening of the inner shell 4. The outer walls of the fruit rollers 6 are arranged in a circular array with multiple fruit protrusions 7. After pressing the two rotating handles 2 to bring the fruit rollers 6 in the two inner shells 4 closer together and clamp the bunches of grapes, the drive assembly drives the fruit rollers 6 in the two inner shells 4 to rotate simultaneously to thin the bunches of grapes. The outer walls of the outer shells 1 are provided with a first protrusion 8 and a second protrusion 9 located on both sides of the second positioning shaft 5. The first protrusion 8 and the second protrusion 9 are respectively threadedly connected to a first adjusting stud 10 and a second adjusting stud 11.

[0024] First loosen the first adjusting stud 10, then tighten the second adjusting stud 11 so that the second adjusting stud 11 pushes the inner shell 4 of the vegetable and fruit machine closer to the front opening around the second positioning shaft 5, while the front openings of the two rows of vegetable and fruit rollers 6 become smaller; similarly, first loosen the second adjusting stud 11, then tighten the first adjusting stud 10 so that the first adjusting stud 10 pushes the inner shell 4 of the vegetable and fruit machine closer to the rear opening around the second positioning shaft 5, while the front openings of the two inner shells 4 of the vegetable and fruit machine move away from each other, while the front openings of the two rows of vegetable and fruit rollers 6 become larger;

[0025] The drive assembly includes a drive motor 12 and a transmission belt 13. The fruit and vegetable roller 6 is mounted on a transmission shaft. One end of the transmission shaft is provided with a transmission wheel. The output end of the drive motor 12 is provided with a drive wheel. The drive wheel and the transmission wheel are connected by the transmission belt 13.

[0026] A return spring 14 is provided between the two rotating handles 2. The return spring 14 and the vegetable and fruit machine housing 1 are respectively located on both sides of the first positioning shaft 3. When the two rotating handles 2 are subjected to external force, they move closer to each other and cause the return spring 14 to contract. When the return spring 14 extends, it causes the two rotating handles 2 to open.

[0027] One of the rotating handles 2 has a fixing stud 15 on the side facing the other rotating handle 2, and the fixing stud 15 is threadedly connected to the adjusting sleeve 16;

[0028] The cross-section of the adjusting screw sleeve 16 is a regular polygon structure, and the cross-section of the adjusting screw sleeve 16 can be a regular square or a regular hexagon.

[0029] Both of the rotating handles 2 are provided with positioning protrusions 17. A positioning ring 18 is rotatably installed on the positioning protrusion 17 of one of the rotating handles 2. When the two rotating handles 2 approach each other until the positioning protrusions 17 on the two rotating handles 2 abut against each other, the positioning ring 18 is snapped onto the other rotating handle 2.

[0030] The outer wall of the vegetable and fruit roller 6 has four vegetable and fruit protrusions 7 arranged in a circular array.

[0031] Both of the vegetable and fruit machine outer shells 1 have an outlet groove 19 on their rear sides, and the vegetable and fruit machine inner shell 4 has an opening groove at its rear end.

[0032] When processing grapes, simply place the two rows of fruit and vegetable rollers 6 from the two outer shells 1 of the fruit and vegetable machine on both sides of the bunch of grapes. Manually press the two rotating handles 2 to make the two rows of fruit and vegetable rollers 6 rotate around the first positioning shaft 3 along with the two outer shells 1 until the bunch of grapes is clamped between the two rows of fruit and vegetable rollers 6. Then, the drive motor 12 works and drives the two rows of fruit and vegetable rollers 6 to rotate simultaneously through the drive wheel, transmission belt 13 and transmission wheel, causing the fruit and vegetable protrusions 7 on the two rows of fruit and vegetable rollers 6 to rotate. The corresponding fruit and vegetable protrusions 7 on the two rows of fruit and vegetable rollers 6 process the grapes. The fallen fruits pass through the opening slot at the rear end of the inner shell 4 of the fruit and vegetable machine. The outlet groove 20 on the outer shell 1 of the fruit and vegetable machine pours out; the size of the openings of the two inner shells 4 of the fruit and vegetable machine can be adjusted according to the size of the bunch of grapes. First loosen the first adjusting screw 10, then tighten the second adjusting screw 11 and make the second adjusting screw 11 push the front opening of the inner shell 4 of the fruit and vegetable machine closer to each other, while the openings of the two rows of fruit and vegetable rollers 6 become smaller; similarly, first loosen the second adjusting screw 11, then tighten the first adjusting screw 10 and make the first adjusting screw 10 push the rear opening of the inner shell 4 of the fruit and vegetable machine closer to each other, so that the front openings of the two inner shells 4 of the fruit and vegetable machine move away from each other, while the openings of the two rows of fruit and vegetable rollers 6 become larger;

[0033] By adjusting the position of the adjusting sleeve 16 on the fixing stud 15, the distance between the adjusting sleeve 16 and the other rotating handle 2 is adjusted. When the two rotating handles 2 are manually pressed to rotate around the first positioning shaft 3, when the adjusting sleeve 16 and the other rotating handle 2 abut against each other, the openings of the two rows of vegetable and fruit rollers 6 inside the two vegetable and fruit machine housings 1 reach their minimum, thereby limiting the minimum included angle between the two vegetable and fruit machine housings 1. After the grape thinning work is completed, the two rotating handles 2 are brought close to each other until the positioning bosses 17 on the two rotating handles 2 abut against each other. The return spring 14 is then compressed, and the positioning ring 18 is then fastened to the other rotating handle 2. Under the action of the return spring 14, the other rotating handle 2 is tensioned on the positioning ring 18, which facilitates the storage and handling of this utility model.
