Description

Technical Field

[0001] This utility model relates to the field of fruit cultivation, and in particular to a separation device with screening function for fruit seed processing. Background Technology

[0002] Fruits generally refer to the fruiting part of a plant, and are usually sweet or sour, suitable for consumption. They contain seeds. Seeds, also known as germinal seeds, are the basic unit of plant reproduction. They contain an embryo and, when conditions are suitable, can germinate and grow into a new plant.

[0003] Currently, since a fruit often contains many seeds, it is often necessary to further screen the separated seeds before planting to select the best seeds suitable for cultivation. Existing seed screening devices, such as the multi-stage screening device for pumpkin seed processing disclosed in CN216779409U, include a main body with bases fixedly connected to both sides of the bottom end of the main body, a cover plate at the top of the main body, a feed inlet on one side of the top of the main body, a blower at the bottom of the feed inlet, an air collector at the output end of the blower, a first guide plate inside the main body, and a discharge port at the bottom of the first guide plate away from the blower. The aforementioned application documents state that the seeds enter the main body of the device through the feed inlet. Under the action of the blower, the smaller seeds are blown to the top of the first guide plate and discharged through the discharge port, while the larger seeds fall onto the surface of the second guide plate and slide onto the surface of the screening plate. Under the action of the electric push rod, the screening plate moves back and forth, so that the seeds on the surface of the screening plate are screened a second time.

[0004] Although the above-mentioned application documents can achieve a good screening effect through secondary screening, in actual use, since larger seeds are often heavier than smaller seeds, blowing the seeds with a blower first may screen out some plump but small seeds, leaving some seeds that are not plump but are large, thus affecting the yield. Therefore, a separation device with screening function for fruit seed processing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a separation device with screening function for fruit seed processing, which aims to improve the problem in the prior art that it is inconvenient to accurately screen seeds of corresponding quality according to the plant size.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 4 One embodiment of this utility model is a separation device with screening function for fruit seed processing, including a machine body 1. The bottom of the machine body 1 is provided with support legs for supporting the equipment, and the top of the machine body 1 is hinged with a baffle 2. By setting the baffle 2, it is ensured that the fruit seeds are not easily shaken out of the machine body 1 due to excessive vibration during the screening process.

[0034] Reference Figure 1 , Figure 3 and Figure 4The machine body 1 has a sieving mechanism 3 both inside and outside. The sieving mechanism 3 includes a sieve plate 31. The inner wall of the sieve plate 31 has multiple vertically connected holes, and the size of the holes increases from right to left. The sieve plate 31 is installed at an angle, and the right side of the sieve plate 31 is higher than the left side. The outer wall of the sieve plate 31 is slidably connected to the inner wall of the machine body 1. Through the angle and the size of the holes, fruit seeds falling above the sieve plate 31 can first pass through the small hole area and then move to the large hole area, thus ensuring that the fruit seeds can finally pass through the holes of the appropriate size. The inner wall of the machine body 1 below the sieve plate 31 is rotatably connected to... A rotating rod 32 is fixedly connected to a cam 33 on its outer wall. The distance between the outer wall of the cam 33 and the rotating rod 32 varies at different positions. A receiving frame 34 is fixedly connected to the inner wall of the machine body 1 below the screen plate 31. A venting plate 35 is fixedly connected to the inner wall of the receiving frame 34. The venting plate 35 is installed at an angle, and the height of the rear end of the venting plate 35 is higher than the height of the front end. The holes opened on the venting plate 35 are smaller than the holes opened on the screen plate 31. A fan 36 is fixedly connected to the inner wall of the receiving frame 34. The fan 36 is located on the inner wall of the receiving frame 34 on the higher side of the venting plate 35, and the vertical position of the fan 36 is the same as the vertical position of the middle part of the venting plate 35.

[0035] Reference Figure 4 - Figure 6 A collection frame 37 is fixedly connected to the outer wall of the machine body 1. A collection drawer 38 is slidably connected to the inner wall of the collection frame 37. The cross-sectional shape of the collection drawer 38 is concave, and the interior of the collection drawer 38 is provided with a partition for distinguishing seeds of different sizes. A collection drawer 39 is slidably connected to the inner wall of the collection frame 37. The shape of the collection drawer 39 is a concave frame connected to a triangular prism. The triangular prism is located on the side of the collection drawer 39 away from the collection drawer 38. The cross-sectional shape of the triangular prism is a right triangle, and the inclined surface of the right triangle is located at the lower end of the side close to the collection drawer 38. Through the shape setting of the collection drawer 39, it is ensured that after the wind blown by the fan 36 blows the seeds into contact with the inclined surface of the triangular prism of the collection drawer 39, it can slowly move downward as the number of seeds blown in increases. A telescopic plate 310 is fixedly connected to the inner wall of the receiving frame 34.

[0036] Reference Figure 2 - Figure 4The machine body 1 is equipped with a rotating assembly 4, which includes a motor 41. The outer wall of the motor 41 is fixedly connected to the inner wall of the machine body 1. The output shaft of the motor 41 is fixedly connected to a rotating rod 42. The length of the rotating rod 42 is the same as the length of the rotating rod 32. The outer wall of the rotating rod 42 is connected to the outer wall of the rightmost rotating rod 32 by a conveyor belt. Adjacent rotating rods 32 are connected by a conveyor belt. Through the transmission connection between each pair, it is ensured that multiple rotating rods 32 can rotate at the same time, thereby ensuring the vibration effect of the screen plate 31.

[0037] Reference Figure 2 - Figure 4 The rotating rod 42 and the machine body 1 are jointly provided with a feeding assembly 5. The feeding assembly 5 includes a chute 51. The rotating rod 42 is located inside the chute 51, which is located on the right inner wall of the machine body 1. A sliding rod 52 is slidably connected to the inner wall of the chute 51. A reciprocating groove 53 is provided on the outer wall of the rotating rod 42. The sliding rod 52 is located outside the reciprocating groove 53. When the rotating rod 42 rotates, the sliding rod 52 can move back and forth under the drive of the reciprocating groove 53. A feeding hopper 54 is fixedly connected to the outer wall of the sliding rod 52. The feeding hopper 54 is shaped as a hollow cuboid at the top, a hollow platform in the middle, and a cuboid at the bottom with a bottom area smaller than the hollow cuboid at the top. The shape of the feeding hopper 54 ensures that the falling speed of the fruit seeds inside the feeding hopper 54 is limited by the size of the bottom opening, thereby avoiding excessive feeding that would affect the screening effect.

[0038] Working principle: When in use, the operator turns on the power of the equipment and pours the fruit seeds to be screened into the hopper 54. When the fruit seeds enter the hopper 54, the feeding speed of the fruit seeds is limited because the opening at the bottom of the hopper 54 is small.

[0039] At the same time, the motor 41 starts and drives the rotating rod 42 to rotate. As the rotating rod 42 rotates, the sliding rod 52 moves back and forth under the control of the reciprocating groove 53. This ensures that the fruit seeds are not on the same horizontal line, thus minimizing interference from other fruit seeds during the screening process.

[0040] Meanwhile, as the rotating rod 42 rotates, the rightmost rotating rod 32 is driven to rotate by the conveyor belt, and all rotating rods 32 rotate through mutual transmission between adjacent rotating rods 32. This causes the rotating rods 32 to drive the cam 33 to rotate. When the cam 33 rotates to the upper position, the cam 33 pushes the sieve plate 31, causing the sieve plate 31 to move upward. When the cam 33 rotates to the lower position, the sieve plate 31 returns to its original position under the action of gravity. Therefore, when the cam 33 continues to rotate, the sieve plate 31 moves up and down, thus generating vibration. This causes the fruit seeds above the sieve plate 31 to vibrate. Since the sieve plate 31 is installed at an angle, when the sieve plate 31 vibrates, it can cause the fruit seeds to move to the left. Since the sieve plate 31 has sieve holes of different sizes, when smaller fruit seeds move to the smaller sieve holes, they can pass through the sieve holes directly and fall down. However, when larger fruit seeds move to the area where the smaller sieve holes are located, they cannot pass through and therefore move to the left until they enter a sieve hole larger than their diameter and fall down.

[0041] After the fruit seeds pass through the sieve holes, they fall above the ventilation plate 35. At this time, because the fan 36 is activated, the lighter fruit seeds can move to the right under the action of the wind until they come into contact with the inclined surface of the triangular prism part of the collection drawer 39. Since the lighter fruit seeds can continue to move to the right, they can push some of the fruit seeds downward until the power of the device is turned off.

[0042] When the power to the device is turned off, the fruit seeds are not affected by the wind. Although the fruit seeds are light and have little weight, they still have gravity. Therefore, they move downwards into the inside of the collection drawer 2 39 under the action of gravity.

[0043] When heavier fruit seeds are subjected to wind, they experience a slightly greater gravitational force and thus enter the collection drawer 38 in a parabolic trajectory. Since the collection frame 37 is equipped with a telescopic plate 310 and multiple fans 36 are provided, the speed of the fans 36 can be adjusted according to the corresponding seed diameter, thus ensuring that the standard weight of seeds of different sizes can be adjusted.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
