Description

Technical Field

[0001] The invention relates to the field of crushing technology, and in particular to a Xanthoceras sorbifolia seed coat crushing and screening component, a device and a screening method. Background Art

[0002] Xanthoceras sorbifolia is a woody oil and medicinal plant with high economic and ecological value. It belongs to the genus Xanthoceras of the Sapindaceae family. Xanthoceras sorbifolia seeds are mainly composed of three parts: seed coat, endosperm and embryo. The oil in Xanthoceras sorbifolia seeds mainly comes from the endosperm, which is the main part for storing nutrients and contains rich oil. The seed coat is the outermost hard shell of the seed, which wraps and protects the embryo and nutrients inside. The seed coat is hard and thick, and direct pressing will hinder the release of oil. Generally, the seeds need to be shelled first to obtain the kernel, and then the oil is extracted by physical pressing or solvent extraction. In the prior art, low-temperature freezing (-20°C to -196°C) is used to freeze the water in the seed coat and expand it, which makes the cell structure brittle and significantly reduces the mechanical strength. The brittle seed coat is easily broken under the action of mechanical force to separate the seed kernel from the seed coat. Screening technology is then used to classify the broken seed coat, seed kernel and impurities according to particle size, thereby achieving efficient separation. The seed coat of Xanthoceras sorbifolia consists of three parts: the outer seed coat, the middle seed coat and the inner seed coat. The outer seed coat is located in the outermost layer and has a thin texture. The middle seed coat is located between the outer seed coat and the inner seed coat and has a relatively loose texture. Since the water content in the outer seed coat and the middle seed coat is relatively high, the embrittlement effect is obvious after freezing, and it can be broken relatively easily. However, in actual application, it was found that there is a membrane structure in the endocarp that is closely attached to the kernel. Because it contains lignin or other hard components, its water absorption is poor. Therefore, the effect of utilizing water freezing and expansion is general, and it is difficult to complete the crushing through a single mechanical impact. Additional mechanical treatment is required during the screening process to completely remove the endocarp. Summary of the invention

[0003] The purpose of the present invention is to provide a Xanthoceras sorbifolia seed coat crushing and screening component, a device and a screening method. By providing a screening component body and a shovel component, when the drum rotates, the Xanthoceras sorbifolia on the shovel can be driven to rub against the spines to peel, and the seed coat and the Xanthoceras sorbifolia kernel can be separated under the action of the negative pressure component.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: A Xanthoceras sorbifolia seed coat crushing and screening component, comprising a screening component body, the screening component body comprising a screen drum, two rotating shafts are rotatably connected to the two sides of the screen drum through a bearing seat, a roller is passed through the rotating shaft, and at least one group of shovel components is arranged on the outer wall of the roller; A thorn strip plate is fixed on the inner side of the sieve cylinder, and a plurality of thorn strips are distributed on the thorn strip plate for crushing the seed coat. A plurality of through holes are opened on the thorn strip plate, and the through holes are connected with the storage cavity installed on the outer wall of the sieve cylinder through an air duct; A negative pressure component is arranged in the storage cavity. When the negative pressure component squeezes the storage cavity, the seed coat attached to the surface of the spine plate can be sucked into the storage cavity through the through hole, and when released, the seed coat can be discharged through the discharge hole opened on the storage cavity.

[0005] Furthermore, the negative pressure assembly includes a slide groove penetrating the ratchet plate and extending into the storage cavity, a telescopic rod is slidably connected in the slide groove, and a piston adapted to the inner wall of the storage cavity is fixedly connected to the telescopic rod.

[0006] Furthermore, the negative pressure assembly also includes a check plate rotatably arranged on both sides of the slide groove, and the check plate can cover the air duct.

[0007] Furthermore, the shoveling assembly includes a fixed seat mounted on the outer wall of the drum, and a mounting shaft is rotatably connected in the fixed seat; One end of the installation shaft is fixedly connected to the material shovel, and the other end of the installation shaft is fixedly connected to the cam, and the cam is matched with the guide assembly through the guide shaft.

[0008] Furthermore, the guide assembly comprises a guide ring fixedly connected to the inner wall of the screen drum via a sleeve rod, and the guide ring is provided with a guide groove matched with the guide shaft.

[0009] Furthermore, the guide groove includes a first guide groove, and the first guide groove is connected to the second guide groove through a special-shaped groove.

[0010] The present application also provides a Xanthoceras sorbifolia seed coat crushing and screening device, including a Xanthoceras sorbifolia seed coat crushing and screening component; and a bracket, the screen cylinder is fixedly mounted on the bracket via a mounting seat, a motor is fixedly mounted on the bracket via a motor seat, an output end of the motor is connected to a rotating shaft, and a driving component for driving a telescopic rod for compression is arranged between the rotating shafts.

[0011] Furthermore, the driving assembly includes two eccentric wheels respectively sleeved on the rotating shaft, the ends of the eccentric wheels are connected to push rods through hinge shafts, and the push rods are rotatably connected to the telescopic rods through hinges.

[0012] A method for crushing and screening Xanthoceras sorbifolia seed coats comprises the following steps: S1. Pour the Xanthoceras sorbifolia into the sieve drum through the feed port; S2. Start the motor, the motor drives the drum to rotate through the shaft, and the drum drives the shovel assembly to scoop up the Xanthoceras sorbifolia in the screen drum during rotation, so that the Xanthoceras sorbifolia rubs against the spines on the spines board to peel; S3. During the rotation of the shaft, the drive assembly drives the telescopic rod to be compressed in the chute, so that the telescopic rod moves into the storage chamber through the piston to form a negative pressure, and the seed coat attached to the slats is sucked into the storage chamber through the air duct; S4. When the drive assembly drives the telescopic rod to be released in the chute, the piston moves out of the storage chamber, the check plate blocks the air duct on the storage chamber, and the piston pushes the air to discharge the seed coat through the discharge hole; S5. Open the discharging port and take out the peeled Xanthoceras sorbifolia kernels from the sieve cylinder.

[0013] The beneficial effects of the present invention are: 1. Through the shovel assembly, as the drum rotates, the drum drives the shovel through the fixed seat to insert into the Xanthoceras sorbifolia in the screen drum, and scoops up the Xanthoceras sorbifolia. A thorn strip plate is fixed on the inner side of the screen drum, and thorn strips for crushing the seed coat are distributed on the thorn strip plate. As the shovel rises, the Xanthoceras sorbifolia can fit the inner wall of the screen drum and transition to the inner wall of the thorn strip plate, so that the Xanthoceras sorbifolia contact and rub against the thorn strips, and the seed coat on the surface of the Xanthoceras sorbifolia is removed. As the drum continues to rotate, the shovel drives the Xanthoceras sorbifolia to continue to rise. When the Xanthoceras sorbifolia transitions to the inner wall of the screen drum again, the shovel is deflected through the guide assembly with the installation shaft as the axis, so that the shovel can be adjusted from a horizontal state to a vertical state, so that the Xanthoceras sorbifolia on the shovel slide down and contact the thorn strips again for secondary friction peeling; 2. Through the set negative pressure component, when the telescopic rod drives the piston to squeeze the storage chamber, negative pressure is generated in the storage chamber, and the seed coat attached to the surface of the spinous plate is sucked into the storage chamber through the through hole. The check plate is driven by the airflow to rotate, and the seed coat can enter the storage chamber through the gap between the check plate and the air duct. When the pressure in the storage chamber is released, the check plate can cover the air duct, and the piston pushes the air to discharge the seed coat through the discharge hole, so that the Xanthoceras sorbifolia can be separated from the seed coat while being crushed.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technology in the embodiments of the present invention, a Xanthoceras sorbifolia seed coat crushing and screening component, device and screening method. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] like Figure 1 - Fig.12 As shown, the present invention proposes a Xanthoceras sorbifolia seed coat crushing and screening device, comprising a Xanthoceras sorbifolia seed coat crushing and screening assembly and a bracket 11, on which a motor 13 is fixedly mounted via a motor seat.

[0018] like Figure 1 and Figure 2 , Fig.10As shown, the Xanthoceras sorbifolia seed coat crushing and screening assembly includes a screening assembly body 20, and the screening assembly body 20 includes a sieve drum 22, which is fixedly mounted on the bracket 11 through a mounting seat 12, and the Xanthoceras sorbifolia is put into the sieve drum 22 through a feed port 221 opened at the top of the sieve drum 22, and a discharge port 222 is provided on the side of the sieve drum 22, and the sieved Xanthoceras sorbifolia kernels are taken out of the sieve drum 22 through the discharge port 222.

[0019] Two rotating shafts 21 are rotatably connected to the screen drum 22 on both sides through bearing seats. The two rotating shafts 21 are connected through a driving assembly 60. The output end of the motor 13 is fixedly connected to one of the rotating shafts 21. Rollers 23 are respectively passed through the rotating shafts 21, and at least one set of shoveling assemblies 40 is arranged on the outer wall of the rollers 23.

[0020] like Figure 2 , Figure 5 and Figure 6 As shown, the shovel assembly 40 includes a fixed seat 41 installed on the outer wall of the drum 23, and a mounting shaft is rotatably connected in the fixed seat 41, and one end of the mounting shaft is fixedly connected to the shovel 42. When the motor 13 drives the rotating shaft 21 to rotate, the drum 23 drives the shovel 42 through the fixed seat 41 to insert into the pile of Xanthoceras sorbifolia in the screen drum 22 to scoop up the Xanthoceras sorbifolia. Preferably, the fixed seat 41 and the shovel 42 are configured as an arc structure, which can increase the contact area between the shovel 42 and the Xanthoceras sorbifolia, and ensure that the shovel 42 can scoop up a sufficient number of Xanthoceras sorbifolia each time. At the same time, the surface of the shovel 42 is provided with a plurality of shovel grooves 421 adapted to the shape of the Xanthoceras sorbifolia, and the scooped Xanthoceras sorbifolia can fall into the shovel grooves 421, so as to prevent the Xanthoceras sorbifolia from rolling off the shovel 42 during the rotation of the drum 23.

[0021] In addition, an arc-shaped spine plate 24 is fixed to the inner side of the screen cylinder 22, and a number of spines are distributed on the spine plate 24 for crushing the seed coat of the Xanthoceras sorbifolia. When the shovel 42 rotates, the scooped Xanthoceras will rise along the inner wall of the screen cylinder 22 and transition to the spine plate 24, so that the Xanthoceras sorbifolia can contact and rub against the spines on the spine plate 24, thereby removing the seed coat on the surface of the Xanthoceras sorbifolia.

[0022] like Figure 6 , Figure 7 and Fig. 9 As shown, in order to control the deflection angle of the shovel 42, the other end of the mounting shaft is fixedly connected to the cam 43, and the cam 43 cooperates with the guide assembly 50 through the guide shaft 44. Specifically, the guide assembly 50 includes a guide ring 52 fixedly connected to the inner wall of the screen drum 22 through a sleeve rod 51, the rotating shaft 21 passes through the guide ring 52 and a gap is reserved between the guide ring 52 and the through hole, and a guide groove adapted to the guide shaft 44 is provided on the guide ring 52.

[0023] Among them, the guide groove includes a first guide groove 53, and the first guide groove 53 is connected with the second guide groove 54 through a special-shaped groove 55. When the guide shaft 44 slides along the trajectories of the first guide groove 53 and the second guide groove 54, the shovel 42 can be placed in a vertical state and a horizontal state respectively, and when the guide shaft 44 transitions from the second guide groove 54 to the first guide groove 53 through the special-shaped groove 55, the guide shaft 44 drives the shovel 42 through the cam 43 under the limit of the fixed seat 41, so that the shovel 42 can switch between a vertical state and a horizontal state. According to the setting position of the special-shaped groove 55, the timing of the switching state of the shovel 42 can be controlled, and when the positions of the first guide groove 53 and the second guide groove 54 remain unchanged, the rotation speed of the shovel 42 can also be controlled according to the length of the set special-shaped groove 55.

[0024] After the seed coat is removed by friction between the Xanthoceras sorbifolia and the spines on the spine plate 24, the shovel 42 is rotated from the spine plate 24 to the inner wall of the screen cylinder 22, and the shovel 42 is deflected with the installation axis as the axis under the action of the special-shaped groove 55, and the shovel 42 is adjusted from a horizontal state to a vertical state (such as Figure 5 ), so that the Xanthoceras sorbifolia can slide onto the curved spine plate 24 at a suitable height, and the Xanthoceras sorbifolia will contact the spines again for secondary friction peeling.

[0025] In addition, the shovel 42 in the vertical state continues to rotate with the drum 23 until it is inserted into the Xanthoceras sorbifolia pile in the screen drum 22. Compared with the horizontal state, the contact area between the shovel 42 in the vertical state and the Xanthoceras sorbifolia pile is smaller, and the motor 13 can more easily drive the shovel 42 to insert into the Xanthoceras sorbifolia pile; and when the shovel 42 is about to be turned out from the Xanthoceras sorbifolia pile or rotated to a shallower position in the Xanthoceras sorbifolia pile, when the shovel 42 is rotated from the vertical state to the horizontal state to scoop up the Xanthoceras sorbifolia, the resistance encountered in scooping up the Xanthoceras sorbifolia is also smaller.

[0026] like Figure 2-Figure 4 As shown, in order to separate the crushed seed coat from the Xanthoceras sorbifolia kernel, the present application provides a storage chamber 25 for collecting the seed coat and a negative pressure assembly 30 on the side of the sieve drum 22, and a plurality of through holes (not shown in the figure) are opened on the spine plate 24, which are connected to the storage chamber 25 installed on the outer wall of the sieve drum 22 through the air duct 26. Under the action of the negative pressure assembly 30, the seed coat can pass through the through holes opened on the spine plate 24 and be sucked into the storage chamber 25 through the air duct 26, thereby completing the separation of the seed coat from the Xanthoceras sorbifolia.

[0027] Specifically, the negative pressure assembly 30 includes a slide groove 32 that passes through the spine plate 24 and extends into the storage chamber 25. A telescopic rod 31 is slidably connected in the slide groove 32. A piston 33 that matches the inner wall of the storage chamber 25 is fixedly connected to the telescopic rod 31. When the telescopic rod 31 drives the piston 33 to squeeze the storage chamber 25, a negative pressure is generated in the storage chamber 25, and the seed coat attached to the surface of the spine plate 24 is sucked into the storage chamber 25 through the through hole. 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 chamber 25.

[0028] like Fig.11 and Fig.12 As shown, the driving assembly 60 includes two eccentric wheels 61 respectively sleeved on the rotating shaft 21, and the ends of the eccentric wheels 61 are connected to push rods 63 through hinge shafts 62, and the push rods 63 are rotatably connected to the telescopic rod 31 through hinges 64. When the rotating shaft 21 rotates, the two eccentric wheels 61 can rotate with the rotating shaft 21 as the axis, so that the push rods 63 sleeved on the hinge shaft 62 can reciprocate, and the push rods 63 are connected to the telescopic rod 31 through hinges 64 set at the ends. Under the limit of the slide slot 32, the push rods 63 can cooperate with the hinges 64 to drive the telescopic rod 31 to reciprocate in the storage chamber 25.

[0029] like Figure 3 and Figure 4 As shown, the negative pressure component 30 also includes a check plate 34 rotatably arranged on both sides of the slide groove 32. When negative pressure is generated in the storage chamber 25, the check plate 34 is pushed by the airflow to rotate, and the check plate 34 rotates toward the storage chamber 25. The seed coat can enter the storage chamber 25 through the gap between the check plate 34 and the air duct 26. When the pressure in the storage chamber 25 is released, the check plate 34 can cover the air duct 26 to prevent the airflow from blowing away the seed coat attached to the spines. At the same time, the piston 33 pushes the air to discharge the seed coat through the discharge hole 35, which can prevent excessive seed coat from accumulating in the storage chamber 25 and affecting the normal movement of the piston 33.

[0030] It should be noted that a torsion spring (not shown in the figure) is installed at the connection between the slide groove 32 and the anti-return plate 34, so that the anti-return plate 34 can be detachably matched with the air duct 26 under the action of the torsion spring.

[0031] The present application also provides a method for crushing and screening Xanthoceras sorbifolia seed coats, comprising the following steps: S1. Pour the Xanthoceras sorbifolia into the sieve drum 22 through the feed port 221; S2. Start the motor 13, the motor 13 drives the drum 23 to rotate through the shaft 21, and the drum 23 drives the shovel assembly 40 to scoop up the Xanthoceras sorbifolia in the screen drum 22 during rotation, so that the Xanthoceras sorbifolia and the spines on the spines plate 24 are peeled by friction; S3. During the rotation of the shaft 21, the drive assembly 60 drives the telescopic rod 31 to be compressed in the chute 32, so that the telescopic rod 31 moves into the storage chamber 25 through the piston 33 to form a negative pressure, and the seed coat attached to the spine plate 24 is sucked into the storage chamber 25 through the air duct 26; S4. When the drive assembly 60 drives the telescopic rod 31 to be released in the chute 32, the piston 33 moves out of the storage chamber 25, the check plate 34 blocks the air duct 26 on the storage chamber 25, and the piston 33 pushes the air to discharge the seed coat through the discharge hole 35; S5. Open the discharge port 222 and take out the peeled Xanthoceras sorbifolia kernels from the sieve cylinder 22.

[0032] The above description is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes to the Xanthoceras sorbifolia seed coat crushing and screening component, device and screening method and the inventive concept according to the technology of the present invention, which should be covered by the protection scope of the present invention.
