Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a pollen purification machine. Background Technology

[0002] In agricultural production, artificial pollination is usually used to achieve high yields of crops.

[0003] Chinese patent CN102273366A discloses a pollen separator, including a support base and a support rod. A power suction device and a straight cylinder are mounted on the support base. A bottom sealing plate is provided at the bottom of the straight cylinder. An anther inlet is provided on the lower side wall of the straight cylinder. A sieve cylinder for sieving pollen from the anthers is placed inside the straight cylinder. The sieve cylinder includes a sieve support frame and a sieve wire wound around the sieve support frame. A top sealing plate is provided at the top of the straight cylinder. The straight cylinder is located on one side of the support rod, and a conical barrel is provided on the other side of the support rod. The straight cylinder and the conical barrel are connected by a connector. A pollen collector is installed at the bottom of the conical barrel. This separator can achieve efficient pollen separation. However, this device still has the following problems: 1. After the anthers enter the straight cylinder, some anthers will adhere to the screen, and pollen will also adhere to the screen, causing the screen to become clogged, which is not conducive to the continuous purification of anthers. 2. The airflow in the straight cylinder flows into the conical cylinder in the same tangential direction as the cone, forming a high-speed spiral airflow, which makes the separated pollen easy to accumulate on the inner wall of the conical cylinder, and the purified pollen also easy to accumulate at the bottom of the conical cylinder.

[0004] Based on this, the present invention designs a pollen purification machine to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a pollen purification machine.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A pollen purification machine includes a support, a decomposing cartridge and a separating cylinder mounted on the support, a blower, and a pollen collection tank detachably connected to the discharge end of the separating cylinder. The decomposing cartridge and the separating cylinder are connected by a connector, and the air inlet of the blower is connected to the top of the separating cylinder through an air duct. A filtration mechanism is installed inside the decoction cartridge. The filtration mechanism includes a filter screen assembly, a rotary drive assembly, an auxiliary decoction cracking assembly, and a filter screen anti-clogging assembly. The filter screen assembly is connected to the inner wall of the upper side of the decoction cartridge. The rotary drive assembly is installed at the top of the decoction cartridge. The filter screen anti-clogging assembly and the auxiliary decoction cracking assembly are installed on the upper and lower sides of the filter screen assembly, respectively. The rotary drive assembly is driven by the filter screen anti-clogging assembly and the auxiliary decoction cracking assembly. The auxiliary decoction cracking assembly is used to crush the anthers attached to the filter screen assembly to crack them. The filter screen anti-clogging assembly is used to vibrate the filter screen assembly and use part of the exhaust gas in the exhaust pipe to backflush the filter screen assembly. The upper end of the separator is equipped with a turbulence reduction mechanism that uses part of the exhaust gas in the exhaust pipe to slow down the airflow flowing into the separator. The lower end of the separator is equipped with an anti-clogging mechanism to prevent the separated pollen from clogging at the discharge end of the separator. The lower end of the support is also equipped with a waste discharge component for receiving waste material from the pollen cartridge.

[0007] Furthermore, the rotary drive assembly includes a motor, a reducer, and a rotating rod. The motor and reducer are fixedly mounted on the top of the detonating cartridge. The input end of the reducer is fixedly connected to the output end of the motor, and the output end of the reducer is fixedly connected to the rotating rod. The rotating rod is rotatably connected to the detonating cartridge.

[0008] Furthermore, the auxiliary crushing assembly includes a crushing roller and a self-rotation drive assembly. One end of the crushing roller is rotatably connected to the rotating rod via a bearing, and the other end of the crushing roller is installed between itself and the inner wall of the crushing cylinder to drive the crushing roller to rotate when it revolves around the rotating rod.

[0009] Furthermore, the filter screen anti-clogging component includes an air-induced backflushing component and a filter screen vibration component. Multiple air-induced backflushing components and filter screen vibration components are equally spaced along the circumference of the rotating rod and correspond one-to-one. The air-induced backflushing component is connected to the rotating rod, and the filter screen vibration component is installed between the air-induced backflushing component and the inner wall of the drug cartridge.

[0010] Furthermore, the air-induced backflushing assembly includes a bypass ventilation pipe, a connecting block, and a backflushing pipe. The connecting block is fixedly installed on the upper end of the reducer and is rotatably connected to the upper end of the rotating rod via a bearing. The two ends of the bypass ventilation pipe are fixedly connected to the exhaust pipe and the bypass ventilation pipe, respectively. The backflushing pipe is located on the upper side of the filter assembly and is fixedly connected to the rotating rod. The lower end of the backflushing pipe has a blowing groove, and the rotating rod has a ventilation groove that communicates with the bypass ventilation pipe and the backflushing pipe.

[0011] Furthermore, the filter vibration assembly includes an elastic striking component and a toggle component. The elastic striking component is connected to the inner wall of the cartridge, and the end of the backflush pipe away from the rotating rod is equipped with a toggle component for driving the elastic striking component.

[0012] Furthermore, the turbulence reduction mechanism includes a second bypass ventilation pipe, a flow control valve, a second filter screen, and a guide plate. The two ends of the second bypass ventilation pipe are fixedly connected to the separation cylinder and the exhaust pipe, respectively. A flow control valve is fixedly installed on the second bypass ventilation pipe. Multiple air outlet slots communicating with the second bypass ventilation pipe are opened on the upper side wall. A second filter screen and a guide plate are fixedly installed in the air outlet slots, and the guide plate is located outside the second filter screen.

[0013] Furthermore, the anti-clogging mechanism includes a induced air blowing rotation component and an elastic striking component two. The induced air blowing rotation component is installed at the lower end of the separator cylinder, and the elastic striking component two is installed at the output end of the induced air blowing rotation component.

[0014] Furthermore, the air-blowing rotating assembly includes a third side ventilation pipe, an impeller, a rotating shaft, and a bracket. The two ends of the third side ventilation pipe are fixedly connected to the exhaust pipe and the separation cylinder, respectively. The third side ventilation pipe extends through the side wall of the separation cylinder and into the separation cylinder. The air outlet at one end of the third side ventilation pipe inside the separation cylinder is vertically downward. The bracket is fixedly connected to the inner wall of the separation cylinder. The rotating shaft is rotatably connected to the bracket through a bearing. The impeller is fixedly connected to the top of the rotating shaft.

[0015] Furthermore, the waste discharge assembly includes a feed pipe, a collection box, and a locking assembly.

The rear end of the collection box is hinged to the lower end of the support, and a locking assembly is provided between the lower end of the support and the collection box to keep the collection box in a horizontal state.

[0016] Compared with the prior art, the beneficial effects of this invention are as follows: 1. The motor drives the rotating rod to rotate through the reducer, which in turn drives the crushing roller and the back-blowing pipe to rotate synchronously. During the revolution, the crushing roller continuously rotates and crushes the anthers attached to the filter screen, accelerating the process of the anthers cracking and releasing pollen. Meanwhile, part of the exhaust gas in the exhaust pipe blows back onto the filter screen through the air trough of the back-blowing pipe. During the revolution of the back-blowing pipe, the back-blowing pipe drives the striking block to strike the filter screen through the driven inclined block and the driving inclined block, causing the filter screen to vibrate continuously. The cooperation between the back-blowing pipe and the striking block makes it difficult for pollen to adhere to the filter screen, avoiding clogging of the filter screen, which is beneficial for the continuous purification of anthers.

[0017] 2. Part of the exhaust gas in the exhaust pipe flows back to the air outlet slot, is filtered by the second filter screen, and its flow direction is controlled by the guide plate. It is blown towards the rotating airflow that flows from the pollen cartridge through the connector into the separation cylinder, so that the pollen loses its rotational force and falls down, avoiding the pollen from colliding with the inner wall of the separation cylinder and accumulating, thus reducing pollen loss.

[0018] 3. Part of the exhaust gas in the exhaust pipe is blown towards the discharge port of the separator through the bypass ventilation pipe three, causing the impeller to rotate. The impeller drives the cam to rotate through the rotating shaft. The cam continuously pushes the slide rod two, causing the slide rod two to strike the side wall of the discharge port of the separator, causing the discharge end of the separator to vibrate continuously. Under the action of the airflow in the bypass ventilation pipe three and the striking action of the striking block two, pollen is effectively prevented from clogging at the discharge port of the separator, which is beneficial to the collection of pollen in the pollen collection tank.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0024] Example 1: In some embodiments, please refer to the accompanying drawings. Figure 1 , Figure 2 and Figure 5 A pollen purification machine includes a support 10, a herb-removing cylinder 11, a separating cylinder 12, a blower 14, and an exhaust pipe 15 fixedly installed on the support 10, and a pollen collection tank 13 detachably connected to the discharge end of the separating cylinder 12. The two ends of the exhaust pipe 15 are fixedly connected to the top of the separating cylinder 12 and the air inlet of the blower 14, respectively. The top of the herb-removing cylinder 11 and the separating cylinder 12 are connected by a connector, so that the airflow in the herb-removing cylinder 11 flows into the separating cylinder 12 along the tangential direction. A feed pipe 16 is fixedly installed on the side wall of the herb-removing cylinder 11. The feed pipe 16 is used to connect with a hose to facilitate the suction and feeding of the herb. A filter mechanism 2 is installed inside the herb-cracking cartridge 11. The filter mechanism 2 includes a filter screen assembly 21, a rotary drive assembly 22, an auxiliary herb-cracking assembly 23, and a filter screen anti-clogging assembly. The filter screen assembly 21 is connected to the inner wall of the upper side of the herb-cracking cartridge 11. The rotary drive assembly 22 is installed on the top of the herb-cracking cartridge 11. The filter screen anti-clogging assembly and the auxiliary herb-cracking assembly 23 are respectively installed on the upper and lower sides of the filter screen assembly 21. The rotary drive assembly 22 is driven to connect with the filter screen anti-clogging assembly and the auxiliary herb-cracking assembly 23. The auxiliary herb-cracking assembly 23 is used to crush the herb attached to the filter screen assembly 21 to crack it. The filter screen anti-clogging assembly is used to vibrate the filter screen assembly 21 and use part of the exhaust gas in the exhaust pipe 15 to back-blow the filter screen assembly 21. The upper end of the separator 12 is equipped with a turbulence reduction mechanism 3 for using part of the exhaust gas in the exhaust pipe 15 to reduce the speed of the airflow flowing into the separator 12. The lower end of the separator 12 is equipped with an anti-clogging mechanism 4 for preventing the separated pollen from clogging at the discharge end of the separator 12. The lower end of the support 10 is also equipped with a waste discharge component 5 for receiving waste material in the decomposed cartridge 11.

[0025] In this invention, the blower 14 is started to allow the anthers to enter the anther-cracking cylinder 11 from the feed pipe 16. The anthers gradually crack open in the anther-cracking cylinder 11, and the separated pollen passes through the filter assembly 21 to the upper part of the anther-cracking cylinder 11. During the separation of anthers and pollen, the rotary drive assembly 22 drives the auxiliary anther-cracking assembly 23 and the filter anti-clogging assembly to operate. The auxiliary anther-cracking assembly 23 continuously crushes the anthers attached to the filter assembly 21 to crack them, making the pollen easier to separate. At the same time, the filter anti-clogging assembly causes the filter assembly 21 to vibrate, and uses part of the exhaust gas in the exhaust pipe 15 to back-blow from the filter assembly 21, effectively preventing the pollen from clogging the filter assembly 21, which is conducive to the continuous operation of pollen purification. Subsequently, the pollen in the splitting cartridge 11 enters the separating cylinder 12 through the connector. The turbulence reduction mechanism 3 uses part of the exhaust gas in the exhaust pipe 15 to blow the airflow from the connector, causing the pollen flowing out of the connector to lose its rotational force and fall downwards, thus preventing the pollen from accumulating on the inner wall of the separating cylinder 12. At the discharge end of the separating cylinder 12, the anti-clogging mechanism 4 continuously taps the side wall of the separating cylinder 12 to prevent the pollen from clogging the discharge port of the separating cylinder 12. The turbulence reduction mechanism 3 and the anti-clogging mechanism 4 work together to effectively reduce the amount of pollen loss. The pollen is then collected by the pollen collection tank 13. After the pollen collection tank 13 is full, it can be removed from the discharge port of the separating cylinder 12.

[0026] The cover plate at the top of the cracking cartridge 11 is connected to the flange of the cracking cartridge 11, which allows the top cover and the filter mechanism 2 to be removed from the top of the cracking cartridge 11 for easy maintenance and cleaning. The cracking cartridge 11 is also detachably assembled from an upper cylindrical body and a lower conical body, which facilitates cleaning of the inner wall of the cracking cartridge 11 and maintenance of the internal parts of the cracking cartridge 11.

Multiple crushing rollers 231 are equally spaced along the circumference of the rotating rod 223. One end of the crushing roller 231 is rotatably connected to the rotating rod 223 via a bearing. The other end of the crushing roller 231 is installed between itself and the inner wall of the drug-cracking cylinder 11, and a self-rotation drive assembly is installed to drive the crushing roller 231 to rotate when it revolves around the rotating rod 223. The self-rotation drive assembly includes a friction wheel 232 and a track 233. The friction wheel 232 is fixedly connected to the rolling roller 231, and the track 233 is fixedly connected to the inner wall of the cracking cartridge 11. The friction wheel 232 and the track 233 are in a rolling connection. In some embodiments, the self-rotating drive assembly adopts a bevel gear and bevel gear drive structure, the bevel gear is fixedly connected to the rolling roller 231, the bevel gear is fixedly connected to the inner wall of the decomposition cartridge 11, and the bevel gear meshes with the bevel gear. The filter screen anti-clogging component includes an air-blowing component 24 and a filter screen vibration component 25. Multiple air-blowing components 24 and filter screen vibration components 25 are equally spaced and correspond one-to-one along the circumference of the rotating rod 223. The air-blowing component 24 is connected to the rotating rod 223. The filter screen vibration component 25 is installed between the air-blowing component 24 and the inner wall of the medicine cartridge 11. The air-induced back-blowing assembly 24 includes a bypass ventilation pipe 241, a connecting block 242, and a back-blowing pipe 244. The connecting block 242 is fixedly installed on the upper end of the reducer 222 and is rotatably connected to the upper end of the rotating rod 223 via a bearing. The two ends of the bypass ventilation pipe 241 are fixedly connected to the exhaust pipe 15 and the bypass ventilation pipe 241, respectively.

The lower end of the back-blowing pipe 244 is provided with a blowing groove, and the rotating rod 223 is provided with a ventilation groove 243 that communicates with the bypass ventilation pipe 241 and the back-blowing pipe 244. The filter vibration assembly 25 includes an elastic striking assembly and a toggle assembly. The elastic striking assembly is connected to the inner wall of the cartridge 11. The backflush pipe 244 is equipped with a toggle assembly for driving the elastic striking assembly at the end away from the rotating rod 223. The elastic striking assembly includes a slide rod 251, a striking block 252, a spring 253, and a connecting frame 254. The slide rod 251 is slidably connected to the inner wall of the cartridge 11. The striking block 252 is fixedly installed at the lower end of the slide rod 251, and the connecting frame 254 is fixedly installed at the upper end of the slide rod 251. The spring 253 is sleeved on the outside of the slide rod 251, and both ends of the spring 253 are fixedly connected to the connecting frame 254 and the inner wall of the cartridge 11, respectively.

In this invention, motor 221 drives rotating rod 223 to rotate via reducer 222, which in turn drives pressing roller 231 and backflush pipe 244 to rotate synchronously. During the revolution of pressing roller 231, friction wheel 232 rolls on track 233, causing pressing roller 231 to continuously rotate and crush the anthers attached to filter screen 212, accelerating the process of anther dehiscence and pollen release. Part of the exhaust gas in exhaust pipe 15 passes through bypass ventilation pipe 241, connecting block 242 and ventilation groove 243 inside rotating rod 223, and finally flows out from the air groove of backflush pipe 244, onto filter screen 212. The filter screen 212 is blown downwards from the side. During the revolution of the backflush pipe 244, the backflush pipe 244 continuously lifts the slide rod 251 through the cooperation of the driven inclined block 255 and the driving inclined block 256. After the driven inclined block 255 and the driving inclined block 256 separate, the slide rod 251 drives the striking block 252 to strike the filter screen 212 under the reset action of the spring 253, causing the filter screen 212 to vibrate continuously. The cooperation of the backflush pipe 244 and the striking block 252 makes it difficult for pollen to adhere to the filter screen 212, avoiding the filter screen 212 from becoming clogged, which is beneficial to the continuous purification of anthers.

[0028] Please see Figure 5 The turbulence reduction mechanism 3 includes a second side ventilation pipe 31, a flow control valve 32, a second filter screen 34, and a guide plate 35. The two ends of the second side ventilation pipe 31 are fixedly connected to the separation cylinder 12 and the exhaust pipe 15, respectively. The flow control valve 32 is fixedly installed on the second side ventilation pipe 31.

It is blown towards the rotating airflow that flows from the pollen cartridge 11 through the connector into the separator 12, causing the pollen to lose its rotational force and fall, avoiding the pollen from colliding with the inner wall of the separator 12 and accumulating, thus reducing pollen loss. Furthermore, the flow rate of the exhaust gas flowing back into the air outlet slot 33 can be controlled by the flow control valve 32, and the airflow can be controlled by the guide plate 35 to achieve accurate deceleration of the pollen airflow.

[0029] Please see Figure 7 and Figure 8 The anti-clogging mechanism 4 includes a induced air blowing rotation component and an elastic striking component 2.

In this invention, part of the exhaust gas in the exhaust pipe 15 is blown towards the discharge port of the separator 12 through the bypass ventilation pipe 3 41, causing the impeller 42 to rotate. The impeller 42 drives the cam 45 to rotate through the rotating shaft 43. The cam 45 continuously pushes the slide bar 2 46, causing the slide bar 2 46 to strike the side wall of the discharge port of the separator 12, causing the discharge end of the separator 12 to vibrate continuously. Under the action of the airflow in the bypass ventilation pipe 3 41 and the striking action of the striking block 2 47, pollen is effectively prevented from clogging the discharge port of the separator 12, which is beneficial to the collection of pollen by the pollen collection tank 13.

When the collection box 52 is in a horizontal state, the bottom of the collection box 52 abuts against the sealing ring at the lower end of the guide pipe 51, so that the anther-breaking cylinder 11 remains sealed. After the anthers are separated, the collection box 52 is rotated downward to separate the collection box 52 from the lower end of the guide pipe 51, and the anthers will slide down along the collection box 52, which facilitates the collection of the anthers.
