Description

Technical Field

[0001] The present invention relates to the technical field of wheat processing, and specifically to a horizontal wheat peeling machine. Background Art

[0002] Wheat is a general term for plants of the genus Triticum. The representative species is common wheat, which is a gramineous plant and a cereal crop widely planted around the world. The caryopsis of wheat is one of the main foods of humans. After being ground into flour, it can be used to make foods such as bread, steamed buns, biscuits, and noodles. After fermentation, it can be made into beer, alcohol, liquor (such as vodka), or biomass fuel. Wheat is one of the three major cereals, almost all of which are used for food, and only about one-sixth is used as feed. In the process of making wheat into flour, machinery is needed to peel the wheat.

[0003] A wheat peeling machine is a mechanical device widely used in the agricultural field. It can remove the outer shell of wheat, thereby improving the processing efficiency of wheat and the quality of grain. The wheat peeling machine mainly consists of a feed inlet, a spiral roller, a discharge outlet, a motor and other components. When wheat enters the feed inlet, after being transported and rubbed by the spiral roller, the outer shell is peeled off, and the wheat grains are discharged through the discharge outlet. This peeling method is not only efficient but also causes less damage to the wheat grains, so it has been widely used.

[0004] Existing wheat peeling machines often only use the same roll gap pressure to process wheat with mixed particle sizes, which will cause situations such as insufficient peeling of small particles or breakage of large particles, thus affecting the product quality of subsequent wheat processing. And the existing equipment simply uses the rotation of the spiral roller to control the peeling process of wheat, making it difficult to completely peel the wheat. At the same time, the fixed sieve mesh used in conjunction with the spiral roller for peeling is prone to clogging and serious local friction, which is not conducive to improving the actual peeling rate of the equipment. The cleaning of the equipment after use is also an urgent problem to be solved. Therefore, those skilled in the art have provided a horizontal wheat peeling machine to solve the problems raised in the above background art. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. In the present invention, by setting the swing screening component, the wheat to be processed can be pre-sorted. After sorting, wheat with different particle sizes can be separately peeled and processed by two sets of peeling components. The small-particle-size wheat is peeled by the spiral groove roller with characteristics such as high linear speed and high-density fine threads, and the large-particle-size wheat is peeled by the spiral groove roller with characteristics such as low linear speed and wide-distance deep grooves. The large-particle-size wheat is peeled strongly, and the small-particle-size wheat is gently treated. After separation, the energy can be accurately matched to reduce the ineffective energy consumption of the equipment. At the same time, the actual peeling rate of wheat can be improved and the breakage rate of wheat can be reduced. Moreover, the sieve barrel of the peeling component can swing together with the screening component, and the wheat generates a compound movement of multi-directional friction between the spiral groove roller and the sieve barrel, which can further improve the wheat epidermis peeling rate and effectively reduce the clogging of the sieve barrel mesh holes by bran and the local wear of the sieve barrel.

[0021] 2. In the present invention, by setting structures such as the connecting piece and the ventilation box connecting the winnowing component, when the equipment is running, the winnowing component can directly convey part of the wind force between the spiral groove roller and the sieve barrel. The air flow can immediately remove the bran generated during processing, which is beneficial to improving the uniformity of wheat peeling, effectively reducing the risk of sieve barrel clogging, and at the same time accelerating the heat dissipation of the equipment. Moreover, the bottom of the ventilation box supported by the elastic member is provided with a cleaning brush. Pressing down the cleaning brush to contact the spiral groove roller can facilitate the automatic cleaning of the equipment. At the same time, the ventilated ventilation box can accelerate the air drying of the internal components of the equipment after use, effectively avoiding the occurrence of mildew and other situations due to internal dampness or impurities after the equipment is used.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1 to 10 , in an embodiment of the present invention, a horizontal wheat peeling machine includes an equipment support 10, a peeling assembly 20, a swing screening assembly 40 and a winnowing assembly 50. The equipment support 10 is used to support the peeling processing box 11. There are two sets of peeling assemblies 20 installed inside the peeling processing box 11. The two sets of peeling assemblies 20 are respectively used to process large-grain wheat and small-grain wheat. An external part of the peeling processing box 11 is provided with a first driving member 30 for controlling the differential rotation of the two sets of peeling assemblies 20. The swing screening assembly 40 includes a screening box 401 with a feeding port 12 at the top. A screening component 402 is arranged inside the screening box 401 fixedly installed on one side of the peeling processing box 11. The screening component 402 is used to screen wheat and deliver the sorted wheat into the corresponding peeling assemblies 20. An external part of the screening box 401 is provided with a second driving member 403 for controlling the left and right swing of the screening component 402 and the outer cylinder of the peeling assembly 20. The winnowing assembly 50 is detachably installed on the equipment support 10 and is used to separate the wheat grains and the outer shells output by the peeling assembly 20. A rice outlet 13 for outputting the wheat grains separated by the winnowing assembly 50 and a bran outlet 14 for the outer shells are arranged at the bottom of the peeling processing box 11.

[0039] When the horizontal wheat peeling machine is actually used, the wheat to be processed is fed from the feeding port 12 onto the screening component 402 inside the screening box 401. The second driving member 403 is started to drive the screening component 402 to swing left and right. The swaying screening component 402 can screen the wheat into two portions of materials with large particle size and small particle size. The screened wheat is respectively delivered into the two sets of peeling assemblies 20. The first driving member 30 is started. The first driving member 30 can drive the rotors of the two sets of peeling assemblies 20 to rotate at the center of the outer cylinder of the peeling assembly 20. While the peeling assembly 20 rubs and peels the wheat, it synchronously conveys the wheat. Moreover, the swaying screening component 402 can synchronously drive the outer cylinder of the peeling assembly 20 to swing around the outer ring of the rotor of the peeling assembly 20, which can generate multi-directional movement of the materials to be peeled, thereby facilitating the improvement of the skinless efficiency of the materials.

[0040] In one embodiment, refer to Figures 1 to 8, Specifically, the peeling assembly 20 includes two sets of rotating rods 201 rotatably connected to the peeling processing box 11 and connected to the first driving member 30. Two sets of retaining discs 202 and spiral groove rollers 203 located between the two sets of retaining discs 202 are fixedly installed on the two sets of rotating rods 201. A sieve barrel 204 is sleeved outside the spiral groove rollers 203 and the two sets of retaining discs 202. The outer circles of the retaining discs 202 are close to the inner walls at both ends of the sieve barrel 204, and the diameter of the retaining discs 202 can be larger than that between the spiral groove rollers 203, which can prevent the processed wheat from directly detaching from the components at both ends of the sieve barrel 204. An elastic bracket 205 for supporting the left-right swing of the sieve barrel 204 is detachably installed inside the peeling processing box 11. A feed hopper 206 that slides and extends into the screening box 401 is connected to the top of one end of the sieve barrel 204, and a discharge hopper 207 located directly above the rice outlet 13 is connected to the bottom of the other end of the sieve barrel 204.

[0041] The material to be processed is fed into the interior of the sieve barrel 204 from the feed hopper 206, and the processed material is conveyed to the outside of the peeling assembly 20 from the discharge hopper 207. The retaining discs 202 and the spiral groove rollers 203 act as the rotors of the peeling assembly 20 to convey and peel the wheat. The sieve barrel 204 that follows the swing of the screening assembly 402 acts as the outer cylinder of the peeling assembly 20 to cooperate with the spiral groove rollers 203 to peel the wheat. The swing of the sieve barrel 204 causes the wheat to generate multi-directional friction (similar to the "kneading" effect) between the spiral groove rollers 203 and the sieve barrel 204, which is especially suitable for hard wheat or wheat with thick cortex. Combining with the propelling force of the spiral groove rollers 203, it forms a compound movement of "forward + left-right tumbling", which can effectively improve the wheat epidermis peeling rate.

[0042] Among them, for the spiral groove rollers 203 used to process small particle sizes, high-density fine threads can be adopted to increase the contact area, and the surface can be treated with diamond sand blasting, etc. The spiral groove rollers 203 for processing small particle sizes run at a high linear speed, and cooperate with the sieve barrel 204 with small mesh holes to peel the bran from the small particle size wheat through micro-cutting. For the spiral groove rollers 203 for processing large particle sizes, wide-distance deep grooves can be adopted to increase the capacity, and the surface can be treated with a tungsten carbide steel layer to increase wear resistance, etc. The spiral groove rollers 203 for processing large particle sizes run at a lower linear speed, increase the processing residence time of the large particle size wheat, and cooperate with the sieve barrel 204 with large mesh holes to form a certain rolling and rubbing movement for the large particle size wheat to peel the bran.

[0043] Correspondingly, the elastic support 205 includes two sets of mounting plates 2051 detachably installed inside the peeling processing box 11. A sliding rod 2052 is fixedly installed between the two sets of mounting plates 2051. Sliding blocks 2053 are welded to the outer circles at both ends of the sieve barrel 204 and are slidably sleeved on the sliding rod 2052. A stopper 2054 is provided in the middle of the sliding rod 2052. A first spring 2055 sleeved on the outer part of the sliding rod 2052 is installed between the stopper 2054 and the sliding block 2053. When the screening assembly 402 pulls the sieve barrel 204 to move, the sieve barrel 204 drives the sliding block 2053 to slide on the sliding rod 2052, and the sliding block 2053 drives the first spring 2055 to expand and contract, which can improve the stability of the swinging operation of the sieve barrel 204.

[0044] Refer to Figures 1 to 6 , specifically, the first driving member 30 includes a first motor 301 fixedly installed on the equipment support 10. The output shaft of the first motor 301 is connected to a first driving wheel 302. The first driving wheel 302 is connected to a first driven wheel 303 through a belt drive. One end of one set of rotating rods 201 is fixedly connected to the middle of the first driven wheel 303. A first gear 304 is fixedly installed at the other end of the rotating rod 201 connected to the first driven wheel 303. The first gear 304 is connected to a second gear 305 through two transmission gears 307. The second gear 305 is fixedly connected to the end of the other set of rotating rods 201. A round rod 306 for supporting the transmission gear 307 is rotatably connected to the side of the peeling processing box 11. One end of the round rod 306 can be welded to one of the components, and the other end is rotatably connected to the other component through a bearing.

[0045] Start the first motor 301. The first motor 301 drives one set of rotating rods 201 and the spiral groove roller 203 to rotate through the first driving wheel 302 and the first driven wheel 303. The above-mentioned rotating rods 201 drive the other set of rotating rods 201 and the spiral groove roller 203 to rotate through the first gear 304, the transmission gears 307 and the second gear 305. By designing a reasonable transmission ratio among the first gear 304, the transmission gears 307 and the second gear 305, for example, when the device is actually operating, the rotation speed of the small particle size roller is 1.5 times that of the large particle size roller, and wheat with different particle sizes is processed separately, which can improve the actual peeling rate of wheat and effectively reduce the breakage rate of wheat during the peeling process.

[0046] On the basis of the above embodiment, refer to Figures 1 to 10, Specifically, the screening component 402 includes two sets of support rods 4021 fixedly installed inside the screening box 401. A swing box 4022 connected to the second driving member 403 is slidably installed on the two sets of support rods 4021. An inclined screening mesh 4023 and a diversion plate 4024 received below the screening mesh 4023 are fixedly installed inside the swing box 4022. Feeding chutes 4025 connecting to the end of the feeding hopper 206 are provided at the inclined bottom ends of both the screening mesh 4023 and the diversion plate 4024. Second springs 4026 sleeved outside the support rods 4021 are installed between both sides of the swing box 4022 and the inner wall of the screening box 401. The swaying swing box 4022 drives components such as the screening mesh 4023 inside it to move. The materials delivered from the feeding port 12 directly fall onto the screening mesh 4023. The screening mesh 4023 can screen the materials. The screened materials fall into the corresponding feeding chutes 4025. The feeding chutes 4025 with an inclined bottom surface can deliver the materials into the feeding hopper 206 for subsequent processing. The swing box 4022 drives the screening barrel 204, etc. to swing through the feeding hopper 206 fixedly connected to it.

[0047] Correspondingly, the second driving member 403 includes two sets of connecting rods 4031 rotatably installed on one side of the screening box 401. Discs 4032 are welded to the adjacent ends of the two sets of connecting rods 4031. A push-pull rod 4034 slidably penetrating through the two sets of moving frames 4033 is fixedly installed between the two discs 4032. Moving rods 4035 slidably extending into the screening box 401 are fixedly installed on the sides of the two sets of moving frames 4033. One end of the moving rod 4035 located inside the screening box 401 is fixedly connected to the swing box 4022. A second driven wheel 4036 is fixedly installed at the end of one set of connecting rods 4031. The second driven wheel 4036 is connected to a second driving wheel 4037 by a belt drive. A second motor 4038 with an output shaft connected to the center of the second driving wheel 4037 is fixedly installed on the equipment support 10.

[0048] Start the second motor 4038. The second motor 4038 drives the connecting rod 4031 to rotate through the second driving wheel 4037 and the second driven wheel 4036. The above-mentioned connecting rod 4031 drives the disc 4032 and the push-pull rod 4034 to rotate. The push-pull rod 4034 drives the moving frame 4033 and the moving rod 4035 to make left and right reciprocating movements. The moving rod 4035 drives the swing box 4022 to slide on the support rod 4021. While the swing box 4022 moves, it drives the second spring 4026 to expand and contract. The second spring 4026 can improve the actual swinging stability of the swing box 4022. The second motor 4038 and the first motor 301 can be stepper motors or servo motors, etc. in the prior art. The specific model can be selected from the corresponding off-the-shelf motors on the market according to the actual size of the equipment.

[0049] In one embodiment, refer to Figures 1 to 9, a support box 15 communicating with its interior is fixedly installed at the top of the sieve barrel 204. An air vent box 17 with multiple groups of ventilation holes 16 at the bottom is slidably installed up and down inside the support box 15. A cleaning brush 18 is fixedly installed at the bottom of the air vent box 17. Two positioning rods 19 that slidably penetrate through the air vent box 17 are fixedly installed inside the support box 15. A limit nut 110 for pressing down the air vent box 17 is threadedly connected to the top end of the positioning rod 19. The limit nut 110 and the positioning rod 19 facilitate the quick assembly of the air vent box 17 into the support box 15. A third spring 111 sleeved on the outer circle of the positioning rod 19 is fixedly installed between the bottom of the air vent box 17 and the support box 15. The third spring 111 can lift the cleaning brush 18 during the operation of the device. The air vent box 17 is communicated with the air separation component 50 through a telescopic hose 113 and a connector 60.

[0050] During the actual use of the horizontal wheat peeling machine, when the air separation component 50 operates, air can be sent into the interior of the air vent box 17 through the connector 60. The air vent box 17 directly ventilates the interior of the sieve barrel 204 through the ventilation holes 16, which can immediately remove the bran generated during processing. The airflow quickly takes away the peeled bran, preventing it from reattaching to the surface of the wheat grains. Ventilation can also help the floating fine bran quickly discharge through the sieve holes. The air vent box 17 can also accelerate the heat dissipation of the device. After the device is used, the connector 60 can be used to press down the air vent box 17 and the cleaning brush 18. The cleaning brush 18 contacts the surface of the spiral groove roller 203, and the cleaning brush 18 can quickly clean the surface of the rotating spiral groove roller 203. The air vent box 17 can quickly air-dry the wet spiral groove roller 203, effectively avoiding mildew inside the device after use.

[0051] Correspondingly, the connector 60 includes a pipe rack 601 detachably connected to the tops of the two telescopic hoses 113. Two shielding covers 114 sleeved on the outer circles of the telescopic hoses 113 are welded on the pipe rack 601. When the air vent box 17 swings with the component, the telescopic hose 113 swings inside the shielding cover 114. Both ends of the pipe rack 601 are communicated with a ventilation pipe 603 through a telescopic pipe 602. The ventilation pipe 603 fixedly installed inside the peeling processing box 11 is used to connect the air separation component 50 and the pipe rack 601. Transverse plates 604 are welded on the outer circles of both ends of the pipe rack 601. A fixing plate 605 is welded at the end of the ventilation pipe 603. A vertical rod 606 that slidably penetrates through the transverse plate 604 is fixedly installed at the top of the fixing plate 605. A fourth spring 607 sleeved on the outside of the vertical rod 606 is installed between the transverse plate 604 and the fixing plate 605. A pressing component 70 for controlling the downward pressure of the pipe rack 601 is provided at the top of the peeling processing box 11. The ventilation pipe 603, the telescopic pipe 602, and the pipe rack 601 can convey part of the ventilation of the air separation component 50 to the air vent box 17. Components such as the fourth spring 607 and the transverse plate 604 can lift components such as the pipe rack 601 and the air vent box 17 during the operation of the device, avoiding the cleaning brush 18 from affecting the normal operation of the device.

[0052] Specifically, the pressing assembly 70 includes an adjusting screw rod 701 threadedly connected to the peeling processing box 11. The bottom end of the adjusting screw rod 701 is rotatably connected to a lower pressing plate 702 that abuts against the top of the pipe support 601. A plurality of limiting rods 703 are fixedly installed on the top of the lower pressing plate 702. A plurality of limiting tubes 704 are fixedly installed on the inner wall of the peeling processing box 11 and are slidably sleeved outside the limiting rods 703. When it is necessary to clean the equipment using the cleaning brush 18, rotate the adjusting screw rod 701 to move the lower pressing plate 702. The movement of the lower pressing plate 702 drives the limiting rods 703 to slide up and down inside the limiting tubes 704. The limiting rods 703 and the limiting tubes 704 can improve the stability of the movement of the lower pressing plate 702. The lower pressing plate 702 can drive the pipe support 601 to move downward. The shielding cover 114 covers the outside of the telescopic hose 113. The inner diameter of the shielding cover 114 is more than half larger than the inner diameter of the telescopic hose 113. The telescopic hose 113 can be selected as a metal hose, etc. The pipe support 601 can drive components such as the ventilation box 17 to press downward through the bottom end of the shielding cover 114. The overall pressing of the components drives the fourth spring 607 and the third spring 111 to compress, enabling the cleaning brush 18 to move downward to contact the spiral groove roller 203. When the lower pressing plate 702 moves upward, the reset of the fourth spring 607 and the third spring 111 can drive the cleaning brush 18 and the pipe support 601 to automatically reset.

[0053] In one embodiment, referring to Figures 1 to 6 , specifically, the winnowing assembly 50 includes a blower 501 detachably installed on the equipment support 10. A wind box 502 communicating with the air outlet of the blower 501 is fixedly installed on the side of the peeling processing box 11. The two top ends of the wind box 502 are communicated with the ends of the ventilation pipes 603. Two ventilation openings 112 corresponding to the discharge hopper 207 are provided between the wind box 502 and the peeling processing box 11.

[0054] Start the blower 501. The blower 501 can blow air into the peeling processing box 11 through the ventilation openings 112 on the side of the wind box 502, capable of separating the peeled wheat and bran falling from the discharge hopper 207. The bran is blown to the outside of the equipment through the bran outlet 14, and the wheat separated from the bran falls to the rice outlet 13 and is conveyed to the outside of the equipment. The wind box 502 can also convey part of the wind force of the blower 501 to the ventilation pipes 603, so as to directly convey the wind force into the sieve barrel 204, thereby improving the actual use performance of the equipment.

[0055] The fixed connection between components can adopt common bolt connection, welding, etc. in the prior art. The rotational connection between components can be achieved through components such as bearings. Most of the components adopt a detachable structure for the subsequent maintenance of the equipment. Other content not described in detail in this specification belongs to the well-known prior art of those skilled in the art.
