Description

Technical Field

[0001] The invention relates to the field of agricultural product processing machinery, in particular to a camellia husk seed sticking and separation machine. Background Art

[0002] Tea oil contains a large amount of unsaturated fatty acids, vitamins and other substances that are beneficial to the human body. It is an edible vegetable oil with high nutritional value. After the oil-tea fruit is harvested, the tea seeds are separated from the fruit shells through drying and shelling. The oil-tea seed is the raw material for extracting tea oil, and the tea seeds need to be selected from the mixture of shells and seeds.

[0003] Existing methods for cleaning the shells and seeds of tea oil fruits mainly include tooth roller sorting, color sorting, and air sorting. Among them, tooth roller sorting requires the squeezing action of the tooth tips on the roller surface, which can easily damage the tea seeds; color sorting utilizes the color difference between tea seeds and fruit shells, such as a crawler color sorter, but the sorting actuator of the color sorter can easily remove some tea seeds along with the fruit shells by blowing air; air sorting separates materials through physical properties such as specific gravity. Since the weight of some fruit shells and tea seeds is similar, many shells and seeds are still not effectively sorted. In summary, the shell and seed cleaning technology of tea oil fruits needs to be further improved.

[0004] In order to improve the cleaning rate of tea seeds and reduce the damage of tea seeds, the prior art discloses a tea fruit and seed sorting machine, which mainly utilizes the different roughness of the surface of tea seeds and fruit shells, adheres the fruit shells in the linear vibrating screen to the cloth through the exciting force and moves with it to the unloading end, and then uses a beating device to remove the fruit shells on the cloth to achieve the function of shell seed cleaning. This sorting method has a good cleaning effect and will not damage the tea seeds. However, the beating head in the beating device of the sorting machine frequently beats the sticky cloth, which will inevitably damage the sticky cloth, thereby affecting the adhesion effect and reducing the cleaning rate. The sticky cloth must be replaced after a certain period of use. Summary of the invention

[0005] In order to improve the problems of low cleaning rate and easy damage of sticky cloth, the present invention provides a camellia husk seed sticking and separating machine and a use method thereof.

[0006] The oil-tea camellia shell seed sticking and separation machine provided by the present invention adopts the following technical scheme: A tea oil shell seed sticking and separation machine, comprising: frame; The sorting drum is installed on the frame and rotates at a low speed driven by the first power mechanism; Adhesive strips, a plurality of adhesive strips are wound around the circumference of the sorting drum at intervals; A distribution plate is arranged on the side of the sorting drum moving upward, a sorting space is formed between the distribution plate and the side of the sorting drum, and a certain gap is reserved between the bottom of the distribution plate and the sorting drum to form a discharge port for discharging tea seeds; Comb teeth are arranged under the sorting roller on the side opposite to the cloth plate, and are used to comb the fruit shells off the sticky strips, and the teeth of the comb teeth just correspond to the gaps between adjacent sticky strips; and The feeding mechanism is used for feeding the shell-seed mixture into the sorting space. Furthermore, the sorting drum is provided with a plurality of annular grooves in its circumference, and the adhesive strips are detachably installed in the annular grooves.

[0007] Furthermore, the sorting drum is a hollow drum for reducing weight.

[0008] Furthermore, the distribution plate is an arc-shaped plate with its bottom bent toward the sorting drum, and end plates are respectively provided at both ends of the arc-shaped plate along the axial direction of the sorting drum, so that a sorting space with a larger top and a smaller bottom is formed between the distribution plate and the side of the sorting drum, and the gap between the bottom of the arc-shaped plate and the side of the sorting drum allows the tea seeds to leak out.

[0009] Furthermore, the two ends of the top of the arc plate are installed on the frame through a first rotating shaft. The arc plate is driven by a swing mechanism to rotate back and forth around the first rotating shaft to change the gap between the arc plate and the sorting roller, so that the shell-seed mixture is beaten and squeezed on the side of the sorting roller.

[0010] Furthermore, the swing mechanism includes an annular tooth provided at the end of the sorting drum and a driving pin provided on the end plate. The driving pin abuts against the annular tooth. During the rotation of the sorting drum, the annular tooth intermittently drives the driving pin, so that the arc plate swings back and forth around the first rotating shaft.

[0011] Furthermore, by selecting the tooth shape of the annular teeth, when the arc plate swings back and forth around the first rotating shaft, the gap between the lower end of the arc plate and the side surface of the sorting drum varies between 3 mm and 25 mm.

[0012] Furthermore, the bottom of the arc plate is tilted so that the bottom of the sorting space is a chute-type slideway, the outlet of the feeding mechanism is located above the high point of the bottom of the arc plate, and a leakage port for discharging tea seeds is provided at the low point of the bottom of the arc plate.

[0013] Furthermore, the comb teeth are mounted on the frame via a second rotating shaft, driven to rotate via a second power mechanism, and the rotating speed of the comb teeth is greater than the rotating speed of the sorting drum.

[0014] Furthermore, the feeding mechanism includes a hopper, a feeding chute and a vibration mechanism. The hopper is used to hold the shell-seed mixture to be sorted. The feeding chute is arranged below the hopper. The upper end of the feeding chute is installed on the frame through a third rotating shaft, and the lower end is suspended on the frame through an elastic member. The discharge port at the lower end of the feeding chute is located above the sorting space. The vibration mechanism is installed on the feeding chute for vibrating and feeding the feeding chute.

[0015] Furthermore, it also includes a tea seed collecting hopper and a fruit shell collecting hopper. The tea seed collecting hopper is arranged below the discharge port of the sorting space, and the fruit shell collecting hopper is arranged below the comb teeth.

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-4 The present invention is described in further detail.

[0021] Example 1 The embodiment of the present invention discloses a tea oil shell seed sticking and separation machine. Figure 1-8 The oil tea fruit shell and seed sticking and separating machine includes a frame 1, a sorting roller 2, a sticking strip 23, a cloth plate 3, comb teeth 4 and a feeding mechanism. The sorting roller 2 is installed on the frame 1 and rotates at a low speed under the drive of a first power mechanism, and the first power mechanism is a first motor 12; a plurality of sticking strips 23 are wound around the circumference of the sorting roller 2 in an intermittent manner; the cloth plate 3 is arranged on the side of the sorting roller 2 on the side where the sorting roller 2 moves upward, and a sorting space is formed between the cloth plate 3 and the side of the sorting roller 2, and a certain gap is reserved between the bottom of the cloth plate 3 and the sorting roller 2 to form a discharge port for discharging tea seeds; the comb teeth 4 are arranged under the sorting roller 2 on the side opposite to the cloth plate 3, and are used to comb off the fruit shells stuck on the sticking strip 23, and the teeth of the comb teeth 4 just correspond to the gaps between adjacent sticking strips 23; and a feeding mechanism is used to feed the shell-seed mixture into the sorting space.

[0022] Since the spacing between adjacent sticky strips 23 is smaller than the maximum size of the shells to be sorted, the comb teeth 4 can comb the shells off by combing the gaps between adjacent sticky strips 23. Since the comb teeth 4 do not contact the sticky strips 23, the sticky strips 23 will not be damaged, thereby increasing the service life of the sticky strips 23. By forming a sorting space between the cloth plate 3 and the side of the sorting drum 2, the sorting efficiency of the oil tea shell seeds is improved, and the damage of the tea seeds during the sorting process is avoided.

[0023] Reference Figure 1 , Figure 2 , Figure 3 The sorting drum 2 is provided with a plurality of annular grooves 22 in the circumferential direction, and the adhesive strip 23 is detachably installed in the annular groove 22. The adhesive strip 23 includes a rubber tube 24 and an adhesive cloth 28 wrapped around the rubber tube 24. A hook 25 is provided inside the rubber tube 24, and the rubber tube 24 is connected end to end through the hook 25.

[0024] Reference Figure 1 The sorting drum 2 is a hollow drum for reducing weight, which helps to reduce equipment costs.

[0025] Reference Figure 1 , Figure 4 , Figure 5 , Figure 6 The distribution plate 3 is an arc-shaped plate 5 whose bottom is bent toward the sorting drum. The arc-shaped plate 5 is provided with end plates 6 at both ends along the axial direction of the sorting drum 2, so that a sorting space with a larger top and a smaller bottom is formed between the distribution plate 3 and the side of the sorting drum 2, and the gap between the bottom of the arc-shaped plate 5 and the side of the sorting drum 2 allows the tea seeds to leak out.

[0026] Furthermore, the two ends of the top of the arc plate 5 are installed on the frame 1 through the first rotating shaft 7. The arc plate 5 is driven by the swing mechanism to rotate back and forth around the first rotating shaft 7, thereby changing the gap between the arc plate 5 and the sorting drum 2, so that the shell-seed mixture is beaten and squeezed on the side of the sorting drum 2.

[0027] Furthermore, the swing mechanism includes an annular tooth 8 provided at the end of the sorting drum 2 and a driving pin 9 provided on the end plate 6. In this embodiment, the annular tooth 8 is a disc cam, and the driving pin 9 abuts against the annular tooth 8. During the rotation of the sorting drum 2, the annular tooth 8 intermittently drives the driving pin 9, so that the arc plate 5 swings back and forth around the first rotating shaft 7.

[0028] Furthermore, by selecting the tooth shape of the annular teeth 8, when the arc plate 5 swings back and forth around the first rotating shaft 7, the gap between the lower end of the arc plate 5 and the side of the sorting drum 2 varies between 3mm and 25mm. Different tooth shapes of the annular teeth 8 can be selected according to shell-seed mixtures of different sizes, which helps to improve the sorting efficiency.

[0029] Furthermore, the bottom of the arc plate 5 is tilted so that the bottom of the sorting space is a chute-type slide 26, the outlet of the feeding mechanism is located above the high point of the bottom of the arc plate 5, and a leakage port 10 for discharging tea seeds is provided at the low point of the bottom of the arc plate 5.

[0030] Reference Figure 5 , Figure 6 The side of the end plate 6 facing the sorting drum 2 is inwardly concave, which helps the distribution plate 3 to swing continuously; the arc plate 5 is a concave arc surface, which helps to reduce the gap between the bottom of the arc plate 5 and the sorting drum 2, and also helps the shell-seed mixture to contact the sorting drum 2 better; the top of the distribution plate 3 is fixedly connected to the side away from the sorting drum 2, and the partition 27 is the same length as the axial length of the sorting drum 2. The partition 27 helps to prevent the shell-seed mixture from falling directly into the tea seed receiving hopper 19 without being cleaned in the sorting space.

[0031] Reference Figure 1 , Figure 7 , Figure 8The comb teeth 4 are mounted on the frame 1 through the second rotating shaft 11, and are driven to rotate by the second power mechanism, the second power mechanism is the second motor 13, and the rotation speed of the comb teeth 4 is greater than the rotation speed of the sorting drum 2, which is helpful to comb the fruit shells on the sticky selection strip 23. There are holes for the steel wire 21 to pass through on the multiple teeth of the comb teeth 4, and the steel wire 21 is connected to form a whole, which is helpful to improve the efficiency of combing the fruit shells.

[0032] Reference Figure 1 The feeding mechanism includes a hopper 14, a feeding chute 15 and a vibration mechanism. The hopper 14 is used to hold the shell-seed mixture to be sorted. The feeding chute 15 is arranged below the hopper 14. The upper end of the feeding chute 15 is installed on the frame through the third rotating shaft 16, and the lower end is suspended on the frame through an elastic member. The elastic member is a spring 17. The lower end discharge port of the feeding chute 15 is located above the sorting space. The vibration mechanism is installed on the feeding chute 15 and is used to vibrate and feed the feeding chute 15. The vibration mechanism is a third motor. The feeding chute 15 is tilted to facilitate the transportation of the shell-seed mixture. The setting of the spring 17 helps to control the vibration deformation range of the feeding chute 15.

[0033] Reference Figure 1 , and also includes a tea seed collecting hopper 19 and a fruit shell collecting hopper 20. The tea seed collecting hopper 19 is arranged below the discharge port of the sorting space, and the fruit shell collecting hopper 20 is arranged below the comb teeth 4.

[0034] The invention provides a method for using a tea husk seed sticking and separation machine using the following technical solutions, referring to Figure 1-8 ,include: Step 1: Put the shell-seed mixture into the feeding mechanism, and as the feeding mechanism vibrates, the shell-seed mixture falls into the sorting space; Step 2: Drive the annular gear 8 at the end of the sorting drum 2 to intermittently move the moving pin 9, so that the arc plate 5 swings back and forth around the first rotating shaft 7, so that the shell-seed mixture is beaten and squeezed on the side of the sorting drum 2, and the shell adheres to the sticky strip 23 and moves away with the rotation of the sorting drum 2. The surface of the tea seed is smooth and is not attached to the sticky strip 23, and falls into the gap between the leakage port 10 at the bottom of the arc plate 5 and the side of the sorting drum 2 into the tea seed receiving hopper 19; Step 3: When the husks rotate with the sorting drum 2 to the comb teeth 4 directly below, the teeth on the comb teeth 4 rotate to comb off the husks adhered to the adhesive strip 23 and drop them into the husk collecting hopper 20, completing the sorting of husks and tea seeds.

[0035] The present invention improves the sorting efficiency of tea husk seeds by using a fast-rotating sorting roller; uses a special material wool-covered sticky cloth to adhere to the husk, thereby avoiding the damage of tea seeds during the sorting process; and designs a sticky strip and comb tooth structure arranged at intervals on the sorting roller so that they do not contact the sticky strip during the sorting process, thereby reducing the replacement frequency of the sticky strip.

[0036] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
