Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery processing, in particular to a full-automatic Chinese prickly ash stalk cutting and grading device. Background Technique

[0002] Chinese prickly ash is a deciduous shrub or small tree, which can be planted alone or used as a protective thorn hedge. Its pericarp can be used as a condiment, can extract aromatic oil, and can also be used as medicine. The seeds can be eaten and can also be processed to make soap; Chinese prickly ash removes the fishy smell of various meats, promotes saliva secretion, and increases appetite; it dilates blood vessels, thus playing a role in lowering blood pressure.

[0003] The Chinese prickly ash stalk refers to the part connecting the Chinese prickly ash fruit and the branch. There are multiple branches of Chinese prickly ash on the branch, and one branch of Chinese prickly ash has multiple Chinese prickly ash stalks connecting to the Chinese prickly ash fruits. The fruits are purplish red, and the diameter of a single mericarp is 4-5 mm. They are usually relatively thick and hard structures. The existence of the Chinese prickly ash stalks makes it necessary to remove the stalks after the Chinese prickly ash fruits are picked to obtain a better taste and flavor.

[0004] The existing method is to first sun-dry the Chinese prickly ash fruits with stalks. During the sun-drying process, the stalks of the Chinese prickly ash fruits will gradually dry out, making them more brittle and easier to separate. Then, the stalks and fruit grains are separated manually. This usually requires a lot of manpower and time because the operator needs to separate the fruit stalks and fruit grains one by one. At the same time, this separation efficiency is relatively slow.

[0005] The authorized publication number: CN219835158U disclosed a Chinese prickly ash stalk removing device on October 17, 2023, which includes a working disk; a number of through holes are provided through the working disk; each through hole is used to hold a Chinese prickly ash, and a part of the Chinese prickly ash protrudes from the through hole; a moving disk is provided on the working disk and contacts the part of the Chinese prickly ash protruding from the through hole; a driving unit is provided on the working disk to drive the moving disk to drive the Chinese prickly ash to rotate in the through hole. In this application, by pouring the Chinese prickly ash onto the working disk and then shaking, each Chinese prickly ash can correspondingly enter a through hole. Then, through the movement of the moving disk, the Chinese prickly ash can rotate in the through hole, so that the Chinese prickly ash stalk contacts the hole wall of the through hole and breaks. The Chinese prickly ash stalks in each through hole can be removed simultaneously. Compared with the method of manually removing Chinese prickly ash stalks, the efficiency of removing Chinese prickly ash stalks is higher. However, the working efficiency of this Chinese prickly ash stalk removing device is low, and it cannot automatically grade the size of Chinese prickly ash grains, and cannot meet the requirements of modern industrialization.

[0018] The utility model has the following advantages:

[0019] 1. In this fully automatic Chinese prickly ash stalk cutting and grading device, the sieve holes of the first, second, and third cylindrical screens are groove-shaped holes. The optimal size of the groove-shaped holes is a width of 1.8 - 2.1 mm and a length of 15 - 25 mm. The length direction is set along the axis of the cylindrical screen. When the Chinese prickly ash branches roll in the cylindrical screen, the branches are likely to insert into the groove-shaped holes of the cylindrical screen with the length direction along the axis of the cylindrical screen, improving the speed of cutting the stalks of Chinese prickly ash and meeting the requirements of modern industrialization. The motor drives the first, second, and third cylindrical screens to rotate through a reduction gearbox, a power output shaft, a transmission shaft, and a transmission shaft gear and a cylindrical screen gear ring. The rotation of the Chinese prickly ash in the cylindrical screen drives the Chinese prickly ash to move in the barrel through the frictional force of the inner wall of the cylindrical screen on the Chinese prickly ash. The movement speed of the Chinese prickly ash is higher than the speed of the Chinese prickly ash sliding at the bottom and lower than the centrifugal movement speed of the Chinese prickly ash, causing the Chinese prickly ash to roll in the barrel. During the rolling process, there is a certain probability that the Chinese prickly ash branches will insert and be stuck in the sieve holes of the second cylindrical screen to complete the fixation of the direction. While the Chinese prickly ash is moving, the Chinese prickly ash branches extend out of the barrel due to the centrifugal force. There are blades closely attached to the cylindrical screen outside the cylindrical screen. The rotation of the cylindrical screen generates a shearing force, completing the work of cutting the stalks while cutting off the Chinese prickly ash branches. The Chinese prickly ash undergoes multiple cuts of the stalks in the cylindrical screen, improving the cleaning rate of the Chinese prickly ash stalks.

[0020] 2. In this fully automatic Chinese prickly ash stalk cutting and grading device, the Chinese prickly ash in the first cylindrical screen rolls and slides from the inlet end to the outlet of the first cylindrical screen and enters the grading cylindrical screen during the rotation of the cylindrical screen. The Chinese prickly ash with the stalks cut rolls and slides in the grading cylindrical screen. The smaller Chinese prickly ash particles fall from the small holes of the grading cylindrical screen into the small particle Chinese prickly ash receiving hopper; the larger Chinese prickly ash particles fall from the large holes of the grading cylindrical screen into the large particle Chinese prickly ash receiving hopper, realizing the automatic grading of the sizes of Chinese prickly ash particles.

[0021] 3. In this fully automatic Chinese prickly ash stalk cutting and grading device, a Chinese prickly ash ejecting device is provided on the frame corresponding to the grading cylindrical screen. The end of the brush is inserted into the large and small holes of the grading cylindrical screen. While the grading cylindrical screen rotates and drives the brush barrel to rotate through the brush, the brush ejects the Chinese prickly ash particles stuck in the large and small holes of the grading cylindrical screen into the cylindrical screen, preventing the large and small holes of the grading cylindrical screen from being blocked by the Chinese prickly ash particles.

[0022] 4. In the rotation support device of the cylindrical screen of this fully automatic Chinese prickly ash stalk cutting and grading device, the outer circle of the support roller is in rolling connection with the outer circle of the cylindrical screen, and the side of the support roller is in rolling contact with the outer side of the retaining ring of the cylindrical screen. This structural design prevents the axial movement and radial jump of the cylindrical screen during rotation, improving the stability of the whole machine.

[0023] 5. The flow - promoting plate set on the cylindrical screen of this fully automatic Chinese prickly ash stalk cutting and grading device, while promoting the Chinese prickly ash to flip, also pushes the Chinese prickly ash from the inlet end of the cylindrical screen to the outlet of the cylindrical screen.

[0024] 6. The feeding ports of the first, second, and third drum screens of this fully automatic Chinese prickly ash stalk-cutting and grading device are inclined with the feeding ports higher than the discharging ports. While the Chinese prickly ash rotates and tumbles along with the drum screens, it is also facilitated to move along the length direction of the drum screen towards the end with the discharging port.

[0025] 7. In this fully automatic Chinese prickly ash stalk-cutting and grading device, a first waste blocking slide plate is inclined front and back on the frame between the first drum screen and the second drum screen, and a second waste blocking slide plate is inclined front and back on the frame between the second drum screen and the third drum screen. While preventing the cut Chinese prickly ash stalks from falling into the lower drum screen, the Chinese prickly ash stalks are slid to one side of the frame, facilitating centralized collection.

[0042] Working principle of this embodiment:

[0043] The Chinese prickly ash is fed into the second feed hopper 9 through the feeding device. The Chinese prickly ash falls from the second feed hopper 9 into the second drum sieve 4. One branch of Chinese prickly ash has multiple prickly ash stalks connected to the prickly ash fruits. The fruits are purplish red, and the diameter of a single fruit lobe is 4 - 5 mm. The branches of the Chinese prickly ash cannot protrude from the smaller round sieve holes of the drum sieve for cutting. If the sieve holes of the drum sieve are too large, the Chinese prickly ash grains will fall out. Through repeated experiments, the sieve holes 4.2 of the second drum sieve are groove-shaped holes. The optimal size of the groove-shaped holes is a width of 1.8 - 2.1 mm and a length of 15 - 25 mm. The length direction is set along the axis direction of the drum sieve. When the Chinese prickly ash branches roll in the drum sieve, the Chinese prickly ash branches are easily inserted into the groove-shaped holes of the drum sieve with the length direction along the axis direction of the drum sieve, which improves the speed of cutting the stalks of Chinese prickly ash and can meet the requirements of modern industrialization. The motor 3.1 drives the second drum sieve 4 to rotate through the speed reducer 3.2, the power output shaft 3.3, the transmission shaft 3.4, the transmission shaft gear 3.6, and the drum sieve gear ring 3.7. The rotation of the Chinese prickly ash in the drum sieve drives the Chinese prickly ash to move in the barrel through the friction force of the inner wall of the drum sieve on the Chinese prickly ash. The movement speed of the Chinese prickly ash is higher than the sliding speed of the Chinese prickly ash at the bottom and lower than the centrifugal movement speed of the Chinese prickly ash, so that the Chinese prickly ash tumbles in the barrel. During the tumbling process, there is a certain probability that the Chinese prickly ash branches are inserted and clamped into the sieve holes 4.2 of the second drum sieve to complete the direction fixation. While the Chinese prickly ash is moving, the Chinese prickly ash branches extend out of the barrel due to the centrifugal force. There are blades closely attached to the drum sieve outside the drum sieve. The rotation of the drum sieve generates a shearing force, and the stalk-cutting work is completed while cutting off the Chinese prickly ash branches.

[0044] The Chinese prickly ash in the second drum sieve 4 tumbles and slides from the inlet end to the discharge port 4.1 of the second drum sieve during the rotation of the drum sieve, and falls into the first drum sieve 7 through the first feed hopper 5. One branch of Chinese prickly ash has multiple prickly ash stalks connected to the prickly ash fruits. The fruits are purplish red, and the diameter of a single fruit lobe is 4 - 5 mm. The branches of the Chinese prickly ash cannot protrude from the smaller round sieve holes of the drum sieve for cutting. If the sieve holes of the drum sieve are too large, the Chinese prickly ash grains will fall out. Through repeated experiments, the sieve holes 7.2 of the first drum sieve are groove-shaped holes. The optimal size of the groove-shaped holes is a width of 1.8 - 2.1 mm and a length of 15 - 25 m. The length direction is set along the axis direction of the drum sieve. The motor 3.1 drives the first drum sieve 7 to rotate through the speed reducer 3.2, the power output shaft 3.3, the transmission shaft 3.4, the transmission shaft gear 3.6, and the drum sieve gear ring 3.7. The rotation of the Chinese prickly ash in the drum sieve drives the Chinese prickly ash to move in the barrel through the friction force of the inner wall of the drum sieve on the Chinese prickly ash. The movement speed of the Chinese prickly ash is higher than the sliding speed of the Chinese prickly ash at the bottom and lower than the centrifugal movement speed of the Chinese prickly ash, so that the Chinese prickly ash tumbles in the barrel. During the tumbling process, there is a certain probability that the Chinese prickly ash branches are inserted and clamped into the sieve holes 7.2 of the first drum sieve to complete the direction fixation. While the Chinese prickly ash is moving, the Chinese prickly ash branches extend out of the barrel due to the centrifugal force. There are blades closely attached to the drum sieve outside the drum sieve. The rotation of the drum sieve generates a shearing force, and the stalk-cutting work is completed while cutting off the Chinese prickly ash branches.

[0045] During the rotation of the first drum screen 7, the Chinese prickly ash in it tumbles and slides from the inlet end to the discharge port 7.1 of the first drum screen and enters the grading drum screen 10. The Chinese prickly ash that has been cut through the handle tumbles and slides on the grading drum screen 10. The smaller Chinese prickly ash particles fall into the small particle Chinese prickly ash receiving hopper 17 through the small holes of the grading drum screen; the larger Chinese prickly ash particles fall into the large particle Chinese prickly ash receiving hopper 18 through the large holes of the grading drum screen, realizing the automatic grading of the sizes of Chinese prickly ash particles.

[0052] The working principle of this embodiment is as follows:

[0053] The Chinese prickly ash is fed into the third feed hopper 14 through the feeding device. The Chinese prickly ash falls into the third drum sieve 14 through the third feed hopper 13. A branch of Chinese prickly ash has multiple Chinese prickly ash stalks connected to the Chinese prickly ash fruits. The fruits are purplish red, and the diameter of a single divided fruit lobe is 4-5 mm. The branches of the Chinese prickly ash cannot protrude from the smaller round sieve holes of the drum sieve for cutting. If the sieve holes of the drum sieve are too large, the Chinese prickly ash grains will fall out. Through repeated experiments, the sieve holes 14.2 of the third drum sieve are groove-shaped holes. The optimal size of the groove-shaped holes is a width of 1.8-2.1 mm and a length of 15-25 mm, and the length direction is arranged along the axis direction of the drum sieve; the motor 3.1 drives the third drum sieve 14 to rotate through the speed reducer 3.2, the power output shaft 3.3, the transmission shaft 3.4, the transmission shaft gear 3.6 and the drum sieve gear ring 3.7. The rotation of the Chinese prickly ash in the drum sieve drives the Chinese prickly ash to move in the barrel through the frictional force of the inner wall of the drum sieve on the Chinese prickly ash. The moving speed of the Chinese prickly ash is higher than the sliding speed of the Chinese prickly ash at the bottom and lower than the centrifugal movement speed of the Chinese prickly ash, so that the Chinese prickly ash tumbles in the barrel. During the tumbling process, there is a certain probability that the Chinese prickly ash branches will be inserted and clamped into the sieve holes 14.2 of the third drum sieve to complete the fixation of the direction. While the Chinese prickly ash is moving, the Chinese prickly ash branches extend out of the barrel due to the centrifugal force. There are blades closely attached to the drum sieve outside the drum sieve. The rotation of the drum sieve generates a shearing force, and while cutting off the Chinese prickly ash branches, the work of cutting the handles is completed; the Chinese prickly ash in the third drum sieve tumbles and slides from the inlet end to the discharge port 14.1 of the third drum sieve during the rotation of the drum sieve, and falls into the second drum sieve 4 through the second feed hopper 9.
