DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] A separation device for extracting pepper seeds according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0036] See also Figure 1-Figure 10 According to an embodiment of the present application, a separation device for extracting pepper seeds includes: a device main frame unloading mechanism 10, a screening mechanism 20, a loading mechanism 30 and a pepper skin breaking mechanism 40.

[0037] Among them, the pepper and onion feeding mechanism 30 is put in, the pepper peeling mechanism 40 completes the pepper peeling, the peeled pepper seeds are screened by the screening mechanism 20 and discharged to the unloading mechanism 10 of the device main frame, and the peeled pepper skin is directly screened out by the screening mechanism 20.

[0038] See also Figure 1 , Figure 4 , Figure 5 and Figure 7 The unloading mechanism 10 of the main frame of the device includes a frame 110 and a lower seed plate 120. The lower seed plate 120 is tilted inside the frame 110. The screening mechanism 20 is installed above the frame 110. The feeding mechanism 30 includes a feeding bin 310 and a guide plate 320. The feeding bin 310 is located above the screening mechanism 20 and is fixedly installed with the frame 110. The guide plate 320 is fixed to one side of the inside of the feeding bin 310, and the right-angle groove area of ​​the lower section of the guide plate 320 is provided with equidistantly distributed strip grooves 340. The pepper peeling mechanism 40 includes a roller 410, a shaft tube 420, an L-shaped nail claw 430 and a rotation drive assembly 450. The roller 410 is fixedly sleeved on the outside of the shaft tube 420, and the shaft tube 420 rotates through the feeding bin 310. A plurality of groups of nail claws 430 are arranged outside the drum 410 in an equidistant and annular array. The rotating nail claws 430 penetrate the strip grooves 340. The drum 410 is provided with convex nails 440 arranged in an equidistant and annular array. The convex nails 440 are staggered with the nail claws 430. The rotation drive assembly 450 is installed on the frame 110, and the rotation drive assembly 450 drives the shaft tube 420 to rotate.

[0039] The working principle of the separation device for extracting pepper seeds is as follows: peppers are put into the upper part of the guide plate 320 inside the upper bin 310, and the peppers slide along the guide plate 320 inside the upper bin 310 to the right angle groove of the lower part of the guide plate 320. At the same time, the rotating drive assembly 450 drives the shaft tube 420 to rotate, and the rotating shaft tube 420 drives the roller 410 to rotate, and the rotating roller 410 drives the external nail claw 430 to rotate. The rotating nail claw 430 falls on the pepper inside the right angle groove, and the rotating nail claw 430 tears the pepper skin apart and breaks it. The crushed pepper seeds and pepper skin fall into the screening mechanism 20 below through the strip groove 340. A gap is reserved between the bottom end of the guide plate 320 and the roller 410 so that the convex nail 440 can pass through. The rotating roller 410 drives the convex nail 440 to rotate, and the pepper skin at the gap can be separated to the upper part of the screening mechanism 20. The method of tearing the pepper skin by rotating nail claws 430 has a better protection effect on pepper seeds than the traditional blade cutting method, and it is not easy to damage the pepper seeds while breaking the skin. The peeled pepper seeds and pepper skin fall into the screening mechanism 20, and the screening mechanism 20 screens the pepper seeds and falls on the seed lower plate 120 for unloading, and the peeled pepper skin is directly unloaded after being screened by the screening mechanism 20.

[0040] In the above specific implementation, please refer to Figure 5 and Figure 7 The pepper peeling mechanism 40 further includes an air pump 460, an air inlet pipe 470 and a cylinder shell 480. The outer side of the cylinder shell 480 is fixedly connected to the frame 110 through a bracket, and one end of the shaft tube 420 is rotatably connected to the cylinder shell 480. The air pump 460 is mounted on the frame 110, one end of the air inlet pipe 470 is connected to the air outlet port of the air pump 460, and the other end of the air inlet pipe 470 is connected to the cylinder shell 480. The nail claw 430 is a hollow tubular structure, and a vent 421 is provided on the outer side of the shaft tube 420 located inside the drum 410.

[0041] The air pump 460 pumps pressurized air into the cylinder shell 480, and the air enters the shaft tube 420 through the cylinder shell 480, and then enters the drum 410 through the vent 421 on the outside of the shaft tube 420. The over-pressurized air inside the drum 410 is then blown out to the upper bin 310 through the nail claws 430 of the tubular structure, and part of the air is directly blown out to the surface of the glass pepper, so that the juice produced when the pepper is peeled can be quickly dried, reducing the probability of the pepper skin or pepper seeds adhering to the surface of the drum 410 or the guide plate 320, and ensuring that the equipment can operate stably for a long time.

[0042] Furthermore, a mounting plate 492 is fixedly provided on the frame 110, and the air pump 460 is installed above the mounting plate 492. Both sides of the upper bin 310 are provided with bearing seats 491 fixed above the frame 110, and the shaft tube 420 is installed in cooperation with the bearing seats 491. The bearing seats 491 are used to stably support the shaft tube 420.

[0043] For specific settings, see Figure 6 The rotation drive assembly 450 includes a driving motor 451, a driving pulley 452 and a driven pulley 453. The driving pulley 452 is fixedly arranged at the output shaft end of the driving motor 451, and the driven pulley 453 is fixedly sleeved outside the shaft tube 420, and the driven pulley 453 and the driving pulley 452 are connected by a transmission belt 454. The driving motor 451 in the rotation drive assembly 450 drives the driving pulley 452 to rotate, and the rotating driving pulley 452 drives the driven pulley 453 to rotate through the transmission belt 454, that is, drives the shaft tube 420 and the roller 410 to rotate.

[0044] Specifically, see Figure 1 The main frame unloading mechanism 10 of the device includes a discharge guide housing 130, which is arranged at one side of the bottom end of the lower seed plate 120. The discharge guide housing 130 is arranged to change the discharge direction of the pepper seeds discharged from the lower seed plate 120. The main frame unloading mechanism 10 of the device also includes a lower skin plate 140, which is located below the screening mechanism 20, and the lower skin plate 140 is fixedly installed with the frame 110, and the pepper skin peeled from the screening mechanism 20 can be smoothly discharged under the guidance of the lower skin plate 140.

[0045] In the above specific implementation, please refer to Figure 2 The screening mechanism 20 includes an outer plate 210, a screen plate 220, a vibration motor 230 and an elastic support part 240. The elastic support part 240 connects the outer plate 210 and the frame 110, the screen plate 220 is fixedly arranged on the inner side of the outer plate 210, and the vibration motor 230 is installed at the bottom of the screen plate 220. The pepper seeds and pepper skins peeled from the upper hopper 310 fall on the screen plate 220 on the inner side of the outer plate 210, and the vibration motor 230 drives the screen plate 220 to vibrate, and the pepper seeds pass through the screen plate 220 and fall onto the lower seed plate 120, and the pepper skins are discharged along the inclined screen plate 220.

[0046] For further information, see Figure 3 The elastic support part 240 includes a shock absorber 241, a fixing plate 242 and a supporting plate 243. The fixing plate 242 is fixed to the outside of the outer plate 210. The supporting plate 243 is fixedly connected to the frame 110. The shock absorber 241 connects the fixing plate 242 and the supporting plate 243. The shock absorber 241 in the elastic support part 240 plays a good shock absorbing role and is used to elastically support the outer plate 210 and the screen plate 220.

[0047] For specific settings, see Figure 4 An inclined loading plate 330 is provided on the side of the loading bin 310 away from the roller 410. The peppers are loaded onto the loading plate 330 above the loading bin 310, and the peppers will slide along the loading plate 330 to the guide plate 320 for smooth loading.

[0048] The compressed air generated by the air pump 460 in the above-mentioned separation device for extracting pepper seeds is finally discharged from the nail claws 430 of the tubular structure on the roller 410. The air discharged from the nail claws 430 cannot be completely discharged outward from the nail claws 430 at the location where the pepper skin is peeled.

[0049] In the above specific implementation, please refer to Figure 8 and Fig. 9 The nail claw 430 includes an L-shaped pipe 431, a sleeve pipe 432, a stopper block 433, a protruding block 434, a connecting column 435 and a spring 436. The bottom end of the pipe 431 is connected to the roller 410, the sleeve pipe 432 is screwed and installed on the top of the pipe 431, and a small hole is provided at the end of the sleeve pipe 432. The connecting column 435 connects the stopper block 433 and the protruding block 434, and the connecting column 435, the protruding block 434 and the stopper block 433 are integrally formed. The small hole at the end of the sleeve pipe 432 is movable. The first ventilation groove 437 is located inside the sleeve pipe 432 to stop the protruding block 434, and the spring 436 is arranged inside the sleeve pipe 432 between the stopper block 433 and the pipe 431. The first ventilation groove 437 is provided on the outside of the stopper block 433, and the second ventilation groove 438 is provided on the outside of the protruding block 434.

[0050] With the cooperation of the spring 436 and the first ventilation groove 437, the small hole at the end of the sleeve tube 432 is blocked, and the air pressurized by the air pump 460 into the drum 410 will not be discharged directly through the pipe 431 and the sleeve tube 432. When the rotating nail claw 430 contacts the pepper skin on the guide plate 320, the protruding block 434 at the end of the pipe 431 contacts the pepper skin in advance to break and peel the pepper skin. When the protruding block 434 is under pressure when contacting the pepper skin, the protruding block 434 will move backward together with the connecting column 435 and the limit block 433 to compress the spring 436, and at this time, the end face of the limit block 433 and the small hole at the end of the sleeve tube 432 are changed from a fitting state to a disengaged state. The air inside the pipe 431 is discharged outward to the peeled pepper surface through the first ventilation groove 437, the small hole and the second ventilation groove 438, so that the peeled portion of the pepper surface can contact with more air, accelerating the air drying speed of the juice when peeling the pepper skin. Similarly, a large amount of wind is discharged from the lower section of the guide plate 320 and near the groove 340, so that the guide plate 320 in the peeling operation section can be in a relatively dry state, reducing the adhesion of pepper skins and pepper seeds to the guide plate 320, and having a good protective effect on the long-term operation of the device.

[0051] When the air pump 460 of the separation device for extracting pepper seeds pressurizes the air, if all the pipes 431 outside the drum 410 or a large number of the pipes 431 are blocked by the first ventilation grooves 437 and cannot vent air, that is, a large number or all of the nail claws 430 are not in a state of peeling the pepper skin, the air pressure inside the drum 410 will continue to increase, which may easily cause damage to the internal components of the device.

[0052] See also Fig.10 The separation device for extracting pepper seeds also includes a pressure relief air drying auxiliary mechanism 50, which includes an air outlet transverse pipe 510, a connecting pipe 520 and a pressure relief valve 530. The air outlet transverse pipe 510 is fixed above the discharge port inside the upper bin 310, and multiple groups of air outlet holes 540 are arranged at the bottom of the air outlet transverse pipe 510. One end of the connecting pipe 520 is connected to the end of the shaft pipe 420 away from the air pump 460, and the other end of the connecting pipe 520 is connected to the air outlet transverse pipe 510, and the pressure relief valve 530 is installed on the connecting pipe 520.

[0053] When the nail claws 430 are not in contact with the pepper skin, or only a few nail claws 430 are in contact with the pepper skin, and the air inside the drum 410 is over-pressurized, the over-pressurized air will be discharged from the connecting pipe 520 to the inside of the air outlet transverse pipe 510 through the pressure relief valve 530, and the over-pressurized air inside the air outlet transverse pipe 510 will be discharged from the air outlet hole 540 at the bottom of the air outlet transverse pipe 510 to the surface of the pepper seeds and pepper skin discharged from the upper bin 310, so that the pepper seeds and pepper skin are further dried. This design can not only protect the device components, but also use the over-pressurized air to dry the pepper seeds and pepper skin, reducing the possibility of the pepper seeds and pepper skin adhering to the device components, which has a good protective effect on the long-term use of the device and is more convenient for later cleaning.

[0054] It should be noted that the specific model specifications of the air pump 460, the drive motor 451, and the vibration motor 230 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail. The power supply and principle of the air pump 460, the drive motor 451, and the vibration motor 230 are clear to those skilled in the art and will not be described in detail here.

[0055] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
