Description

Technical Field

[0001] The present invention relates to the technical field of crushing, and particularly relates to a component, a device and a screening method for breaking and screening the pericarp of Xanthoceras sorbifolium Bunge seeds. Background Art

[0002] Xanthoceras sorbifolium Bunge is a woody oil and medicinal plant with high economic and ecological value. It belongs to the genus Xanthoceras of the family Sapindaceae. The seeds of Xanthoceras sorbifolium Bunge mainly consist of three parts: pericarp, endosperm and embryo. The oil of Xanthoceras sorbifolium Bunge seeds mainly comes from the endosperm. The endosperm is the main part storing nutrients, which contains rich oil. The pericarp is the hard shell on the outermost layer of the seeds, wrapping and protecting the internal embryo and nutrients. The pericarp is hard and thick, and direct pressing will hinder the release of oil. Generally, the seeds need to be shelled first to obtain kernels, and then the oil is extracted by methods such as physical pressing or solvent extraction;

[0003] In the prior art, by means of cryogenic freezing (-20°C to -196°C), the water in the pericarp freezes and expands, the cell structure becomes brittle, and the mechanical strength is significantly reduced. The brittle pericarp is easily broken under the action of mechanical force to realize the separation of the kernel and the pericarp, and then screening technology is used to classify the broken pericarp, kernel and impurities according to particle size, so as to achieve efficient separation;

[0004] The pericarp of Xanthoceras sorbifolium Bunge consists of three parts: exocarp, mesocarp and endocarp. The exocarp is located on the outermost layer and has a relatively thin texture. The mesocarp is located between the exocarp and the endocarp and has a relatively loose texture. Since the water content in the exocarp and mesocarp is relatively large, the embrittlement effect is obvious after freezing, and the crushing can be completed relatively simply;

[0005] However, in the actual application process, it is found that there is a membranous structure in the endocarp that adheres closely to the kernel. Due to the presence of lignin or other hard components, its water absorption is poor. Therefore, the effect of using water freezing and expansion is average, and it is difficult to complete the crushing by a single mechanical impact. Extra mechanical treatment is required during the screening process to completely remove the endocarp. Summary of the Invention

[0006] The purpose of the present invention is to provide a component, a device and a screening method for breaking and screening the pericarp of Xanthoceras sorbifolium Bunge seeds. When the roller rotates, it can drive the Xanthoceras sorbifolium Bunge fruits on the material shovel to rub off the skin with the thorn strips, and under the action of the negative pressure component, the pericarp is separated from the kernel of Xanthoceras sorbifolium Bunge.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A Xanthoceras sorbifolium seed coat crushing and screening assembly, including a screening assembly body, the screening assembly body includes a screening cylinder, both sides of the screening cylinder are rotatably connected with two rotating shafts through bearing seats, a roller is sleeved on the rotating shafts, and at least one set of material shoveling components is arranged on the outer wall of the roller;

[0009] A thorn strip plate is fixed inside the screening cylinder, several thorn strips for crushing the seed coat are distributed on the thorn strip plate, several through holes are opened on the thorn strip plate, and the through holes are communicated with a storage cavity installed on the outer wall of the screening cylinder through an air duct;

[0010] A negative pressure component is arranged in the storage cavity. When the storage cavity is squeezed, the seed coat attached to the surface of the thorn strip plate can be sucked into the storage cavity through the through holes, and when released, the seed coat can be discharged through a discharge hole opened on the storage cavity.

[0011] Further, the negative pressure component includes a chute penetrating through the thorn strip plate and extending into the storage cavity, a telescopic rod is slidably connected in the chute, and a piston adapted to the inner wall of the storage cavity is fixedly connected to the telescopic rod.

[0012] Furthermore, the negative pressure component further includes check valves rotatably arranged on both sides of the chute, and the check valves can cover the air duct.

[0013] Further, the material shoveling component includes a fixed seat installed on the outer wall of the roller, and a mounting shaft is rotatably connected inside the fixed seat;

[0014] One end of the mounting shaft is fixedly connected with a material shovel, the other end of the mounting shaft is fixedly connected with a cam, and the cam is matched with a guiding component through a guiding shaft.

[0015] Further, the guiding component includes a guiding ring fixedly connected to the inner wall of the screening cylinder through a sleeve rod, and a guiding groove adapted to the guiding shaft is opened on the guiding ring.

[0016] Further, the guiding groove includes a first guiding groove, and the first guiding groove is communicated with a second guiding groove through a special-shaped groove.

[0017] This application also provides a Xanthoceras sorbifolium seed coat crushing and screening device, including a Xanthoceras sorbifolium seed coat crushing and screening assembly; and a bracket. The screening cylinder is fixedly installed on the bracket through a mounting seat, a motor is fixedly installed on the bracket through a motor seat, the output end of the motor is connected to the rotating shaft, and a driving component for driving the telescopic rod to be compressed is arranged between the rotating shafts.

[0018] Further, the driving component includes two eccentric wheels respectively sleeved on the rotating shafts, a push rod is connected to the end of the eccentric wheel through a hinge shaft, and the push rod is rotatably connected to the telescopic rod through a hinge.

[0019] A method for crushing and screening the seed coat of Xanthoceras sorbifolium Bunge, comprising the following steps:

[0020] S1. Pour Xanthoceras sorbifolium Bunge into the sieve cylinder through the feed inlet;

[0021] S2. Start the motor. The motor drives the roller to rotate through the rotating shaft. During the rotation of the roller, the shoveling component is driven to shovel up the Xanthoceras sorbifolium Bunge in the sieve cylinder, so that the Xanthoceras sorbifolium Bunge rubs against the thorns on the thorn plate to remove the skin;

[0022] S3. During the rotation of the rotating shaft, the driving component drives the telescopic rod to compress in the chute, so that the telescopic rod moves into the storage cavity through the piston to form a negative pressure, and the seed coat attached to the thorn plate is sucked into the storage cavity through the air duct;

[0023] S4. When the driving component drives the telescopic rod to be released in the chute, the piston moves out of the storage cavity, the check valve plate blocks the air duct on the storage cavity, and the piston pushes the air to discharge the seed coat through the discharge hole;

[0024] S5. Open the discharge port and take out the peeled Xanthoceras sorbifolium Bunge kernels from the sieve cylinder.

[0025] The beneficial effects of the present invention are:

[0026] 1. Through the arranged shoveling component, as the roller rotates, the roller drives the material shovel to insert into the Xanthoceras sorbifolium Bunge in the sieve cylinder through the fixed seat, shoveling up the Xanthoceras sorbifolium Bunge. The thorn plate is fixed on the inner side of the sieve cylinder, and thorns for crushing the seed coat are distributed on the thorn plate. As the material shovel rises, the Xanthoceras sorbifolium Bunge can fit on the inner wall of the sieve cylinder and transition to the inner wall of the thorn plate, so that the Xanthoceras sorbifolium Bunge contacts and rubs against the thorns, and the seed coat on the surface of the Xanthoceras sorbifolium Bunge is removed. As the roller continues to rotate, the material shovel drives the Xanthoceras sorbifolium Bunge to continue to rise. When the Xanthoceras sorbifolium Bunge re-transitions to the inner wall of the sieve cylinder, the material shovel deflects around the installation shaft through the guiding component, so that the material shovel can be adjusted from a horizontal state to a vertical state, and the Xanthoceras sorbifolium Bunge on the material shovel slides off and contacts the thorns again for secondary friction to remove the skin;

[0027] 2. Through the arranged negative pressure component, when the telescopic rod drives the piston to extrude the storage cavity, a negative pressure is generated in the storage cavity, and the seed coat attached to the surface of the thorn plate is sucked into the storage cavity through the through hole. The check valve plate rotates under the push of the air flow, and the seed coat can enter the storage cavity through the gap between the check valve plate and the air duct. When the pressure in the storage cavity is released, the check valve plate can cover the air duct, and the piston pushes the air to discharge the seed coat through the discharge hole, which can separate the Xanthoceras sorbifolium Bunge from the seed coat while crushing it.

[0047] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions of a Xanthoceras sorbifolium seed coat crushing and screening component, device and screening method in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0048] As Figure 1 - Figure 12 As shown, the present invention provides a Xanthoceras sorbifolium seed coat crushing and screening device, including a Xanthoceras sorbifolium seed coat crushing and screening component and a bracket 11. A motor 13 is fixedly installed on the bracket 11 through a motor seat.

[0049] As Figure 1 and Figure 2 , Figure 10 As shown, the Xanthoceras sorbifolium seed coat crushing and screening component includes a screening component body 20. The screening component body 20 includes a screening cylinder 22. The screening cylinder 22 is fixedly installed on the bracket 11 through a mounting seat 12. Xanthoceras sorbifolium is put into the screening cylinder 22 through a feeding port 221 opened at the top of the screening cylinder 22. A discharge port 222 is arranged on the side of the screening cylinder 22. The screened Xanthoceras sorbifolium kernels are taken out of the screening cylinder 22 through the discharge port 222.

[0050] Two rotating shafts 21 are rotatably connected to both sides of the screening cylinder 22 through bearing seats. The two rotating shafts 21 are connected by a driving component 60. The output end of the motor 13 is fixedly connected to one of the rotating shafts 21. Drums 23 are respectively sleeved on the rotating shafts 21. At least one set of material shoveling components 40 is arranged on the outer wall of the drum 23.

[0051] As Figure 2 , Figure 5 and Figure 6 As shown, the material shoveling component 40 includes a fixed seat 41 installed on the outer wall of the drum 23. A mounting shaft is rotatably connected in the fixed seat 41. One end of the mounting shaft is fixedly connected to a material shovel 42. When the motor 13 drives the rotating shaft 21 to rotate, the drum 23 drives the material shovel 42 through the fixed seat 41 to be able to insert into the Xanthoceras sorbifolium fruit pile in the screening cylinder 22 and shovel up the Xanthoceras sorbifolium. Preferably, the fixed seat 41 and the material shovel 42 are arranged in an arc structure, which can increase the contact area between the material shovel 42 and the Xanthoceras sorbifolium and ensure that the material shovel 42 can shovel up a sufficient number of Xanthoceras sorbifolium each time. At the same time, a plurality of shovel grooves 421 adapted to the shape of the Xanthoceras sorbifolium are arranged on the surface of the material shovel 42, and the shoveled Xanthoceras sorbifolium can fall into the shovel grooves 421 to prevent the Xanthoceras sorbifolium from rolling off the material shovel 42 during the rotation of the drum 23.

[0052] In addition, a ratchet bar plate 24 with an arc-shaped structure is fixed inside the sieve cylinder 22. A number of ratchet bars for crushing the pericarp of Xanthoceras sorbifolium are distributed on the ratchet bar plate 24. During the rotation of the material shovel 42, the shoveled Xanthoceras sorbifolium will rise along the inner wall of the sieve cylinder 22 and transition to the ratchet bar plate 24, enabling the Xanthoceras sorbifolium to come into contact with and rub against the ratchet bars on the ratchet bar plate 24, removing the pericarp on the surface of the Xanthoceras sorbifolium.

[0053] As Figure 6 , Figure 7 and Figure 9 shown, in order to control the deflection angle of the material shovel 42, the other end of the mounting shaft is fixedly connected to a cam 43, and the cam 43 is cooperatively connected with a guiding assembly 50 through a guiding shaft 44. Specifically, the guiding assembly 50 includes a guiding ring 52 fixedly connected to the inner wall of the sieve cylinder 22 through a sleeve rod 51. The rotating shaft 21 passes through the guiding ring 52 with a gap reserved between them, and a guiding groove adapted to the guiding shaft 44 is formed on the guiding ring 52.

[0054] Among them, the guiding groove includes a first guiding groove 53, and the first guiding groove 53 is communicated with a second guiding groove 54 through a special-shaped groove 55. When the guiding shaft 44 slides along the trajectories of the first guiding groove 53 and the second guiding groove 54, the material shovel 42 can be in a vertical state and a horizontal state respectively. Moreover, when the guiding shaft 44 transitions from the second guiding groove 54 to the first guiding groove 53 through the special-shaped groove 55, the guiding shaft 44 drives the material shovel 42 under the limit of the fixed seat 41, enabling the material shovel 42 to switch between the vertical state and the horizontal state. According to the setting position of the special-shaped groove 55, the timing of the state switching of the material shovel 42 can be controlled. And when the positions of the first guiding groove 53 and the second guiding groove 54 remain unchanged, according to the set length of the special-shaped groove 55, the rotation speed of the material shovel 42 can also be controlled.

[0055] After the Xanthoceras sorbifolium rubs against the ratchet bars on the ratchet bar plate 24 to remove the pericarp, the material shovel 42 rotates from the ratchet bar plate 24 to the inner wall of the sieve cylinder 22. The material shovel 42 will deflect with the axis of the mounting shaft under the action of the special-shaped groove 55. The material shovel 42 is adjusted from the horizontal state to the vertical state (as Figure 5 ), enabling the Xanthoceras sorbifolium to slide down to the curved ratchet bar plate 24 at an appropriate height, and the Xanthoceras sorbifolium will come into contact with the ratchet bars again for secondary friction to remove the skin.

[0056] In addition, the vertical material shovel 42 continues to rotate with the drum 23 until it inserts into the Xanthoceras sorbifolium fruit pile inside the sieve cylinder 22. Compared with the horizontal state, the contact area between the vertical material shovel 42 and the Xanthoceras sorbifolium fruit pile is smaller, and it is easier for the motor 13 to drive the material shovel 42 to insert into the Xanthoceras sorbifolium fruit pile. Moreover, when the material shovel 42 is about to turn out of the Xanthoceras sorbifolium fruit pile or rotates to a shallower position of the Xanthoceras sorbifolium fruit pile, when the material shovel 42 rotates from the vertical state to the horizontal state to scoop up the Xanthoceras sorbifolium, the resistance to scooping up the Xanthoceras sorbifolium is also smaller.

[0057] As Figures 2 - 4 shown, in order to separate the broken seed coat from the Xanthoceras sorbifolium kernel, a storage cavity 25 for collecting the seed coat and a negative pressure component 30 are provided on the side of the sieve cylinder 22 in this application. A number of through holes (not shown in the figure) are opened on the thorn strip plate 24, and the through holes are connected to the storage cavity 25 installed on the outer wall of the sieve cylinder 22 through an air duct 26. Under the action of the negative pressure component 30, the seed coat can pass through the through holes opened on the thorn strip plate 24 and be sucked into the storage cavity 25 through the air duct 26, completing the separation of the seed coat from the Xanthoceras sorbifolium.

[0058] Specifically, the negative pressure component 30 includes a chute 32 that penetrates the thorn strip plate 24 and extends into the storage cavity 25. A telescopic rod 31 is slidably connected in the chute 32. A piston 33 adapted to the inner wall of the storage cavity 25 is fixedly connected to the telescopic rod 31. When the telescopic rod 31 drives the piston 33 to squeeze the storage cavity 25, a negative pressure is generated in the storage cavity 25, sucking the seed coat attached to the surface of the thorn strip plate 24 into the storage cavity 25 through the through holes. When the telescopic rod 31 drives the piston 33 to release, the seed coat can be discharged through the discharge hole 35 opened on the storage cavity 25.

[0059] As Figure 11 and Figure 12 shown, the drive component 60 includes two eccentric wheels 61 sleeved on the rotating shaft 21 respectively. The end of the eccentric wheel 61 is connected to a push rod 63 through a hinge shaft 62, and the push rod 63 is rotatably connected to the telescopic rod 31 through a hinge member 64. When the rotating shaft 21 rotates, the two eccentric wheels 61 can rotate around the rotating shaft 21 as the axis, making the push rod 63 sleeved on the hinge shaft 62 perform a reciprocating motion. The push rod 63 is connected to the telescopic rod 31 through the hinge member 64 provided at the end. Under the limit of the chute 32, the push rod 63 can cooperate with the hinge member 64 to drive the telescopic rod 31 to reciprocate in the storage cavity 25.

[0060] As Figure 3 and Figure 4As shown, the negative pressure component 30 further includes check valves 34 rotatably arranged on both sides of the chute 32. When negative pressure is generated in the storage cavity 25, the check valves 34 are pushed by the air flow to rotate. The check valves 34 rotate towards the storage cavity 25, and the seed coats can enter the storage cavity 25 through the gap between the check valves 34 and the air duct 26. When the pressure in the storage cavity 25 is released, the check valves 34 can cover the air duct 26 to prevent the air flow from blowing away the seed coats attached to the thorn bars. At the same time, the piston 33 pushes the air to discharge the seed coats through the discharge holes 35, which can prevent excessive accumulation of seed coats in the storage cavity 25 and affect the normal movement of the piston 33.

[0061] It should be noted that a torsion spring (not shown in the figure) is installed at the connection between the chute 32 and the check valve 34, so that the check valve 34 can be detachably engaged with the air duct 26 under the action of the torsion spring.

[0062] The present application also provides a method for crushing and screening the seed coats of Xanthoceras sorbifolium, including the following steps:

[0063] S1. Pour Xanthoceras sorbifolium into the sieve cylinder 22 through the feed port 221;

[0064] S2. Start the motor 13. The motor 13 drives the roller 23 to rotate through the rotating shaft 21. During the rotation of the roller 23, the shoveling component 40 drives the Xanthoceras sorbifolium in the sieve cylinder 22 to be shoveled up, so that the Xanthoceras sorbifolium rubs off the skin with the thorns on the thorn bar plate 24;

[0065] S3. During the rotation of the rotating shaft 21, the driving component 60 drives the telescopic rod 31 to be compressed in the chute 32, so that the telescopic rod 31 moves towards the storage cavity 25 through the piston 33 to form negative pressure, and the seed coats attached to the thorn bar plate 24 are sucked into the storage cavity 25 through the air duct 26;

[0066] S4. When the driving component 60 drives the telescopic rod 31 to be released in the chute 32, the piston 33 moves out of the storage cavity 25, the check valve 34 blocks the air duct 26 on the storage cavity 25, and the piston 33 pushes the air to discharge the seed coats through the discharge holes 35;

[0067] S5. Open the discharge port 222 and take out the peeled Xanthoceras sorbifolium kernels from the sieve cylinder 22.

[0068] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
