Description

Technical Field

[0001] This invention relates to the field of agricultural plant pollination mechanism technology, specifically to pollination equipment for large-scale rice seed production. Background Technology

[0002] The main existing pollination methods for plants are as follows: 1. Natural pollination: This is the pollination process that occurs naturally within the plant itself. Pollen moves from the anther to the stigma of the same flower. This process is called self-pollination. Examples include peas and wheat. 2. Artificial pollination: This is a human-assisted pollination method. Pollen is transferred manually or mechanically from the stamen of one flower to the pistil of another. This method can improve fruit set and is commonly used in agricultural production. 3. Cross-pollination: This refers to the movement of pollen from the stamen of one flower to the pistil of another. This process usually involves insects or wind as pollinators. 4. Mechanical pollination: Using specialized equipment, such as a pollinator or pollination gun, to precisely disperse pollen onto the stigma of a flower. This method can improve pollination efficiency and accuracy.

[0003] Rice is a monocotyledonous plant belonging to the Poaceae family and is one of the main food crops for humans. Rice is pollinated by powdery pollen. Its inflorescence is a cyme, and only the spikelets within the inflorescence open, while the male reproductive organs are attached to the inside of the spikelets, which are called florets. Both male and female flowers of rice exist on the same plant; this morphology is called "self-incompatible monoculture," meaning rice is self-pollinating. Rice pollination occurs in two ways: self-pollination and cross-pollination.

[0004] For some types of rice, mechanical pollination is required to help them bear fruit. In this case, electric pollinators are often used for pollination. However, this method is labor-intensive and cannot meet the requirements of fast, large-scale, and low-cost artificial pollination. Moreover, the quantitative control of pollen cannot be effectively adjusted, resulting in uneven pollination. In addition, excessive pollen can easily cause blockages in the pipes, which is detrimental to the normal use of the equipment.

[0005] Therefore, we now need large-scale rice seed pollination equipment to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a pollination device for large-scale rice seed production to solve the problems of high labor intensity in existing devices, which cannot meet the requirements of rapid, large-scale and low-cost artificial pollination, and the inability to effectively regulate the quantitative control of pollen.

[0007] The objective of this invention can be achieved through the following technical solutions: Pollination equipment for large-scale rice seed production includes: case; A feeding mechanism is installed on a conical hopper at the top of the housing, and the feeding mechanism is used to quantitatively control and transport pollen. The fan mechanism includes ventilation holes on both sides of the front end of the housing. A first rotating shaft is movably mounted on the inner wall of the ventilation hole via a bracket. One end of the first rotating shaft is connected to the output shaft of the first motor via a first conveyor belt, and the other end extends to the blades. When the fan mechanism is working, an airflow is formed in the feed tube to transport pollen. The guide pipe is Y-shaped and connected to the bottom of the guide mechanism. A discharge pipe is fixedly connected to one end of the guide pipe away from the ventilation hole. The discharge pipe is fan-shaped and the inner wall of the discharge pipe is equipped with partitions through crossbeams. A guide groove is formed between the partitions and placed inside the discharge pipe.

[0008] Furthermore, the material guiding mechanism includes a second motor placed on a conical hopper, the output shaft of the second motor extending to a roller inside the conical hopper, the roller being equipped with a ring array of baffles, a quantitative region being formed between the baffles and the inner wall of the conical hopper, and a baffle assembly being driven and connected to the output shaft of the second motor via a second conveyor belt.

[0009] Furthermore, the partition assembly includes a second rotating shaft that is connected to the second conveyor belt. One end of the second rotating shaft is fixed to a first bevel gear. The outer wall of the first bevel gear meshes with a second bevel gear fixed to a third rotating shaft. The second bevel gear is equipped with rotating teeth arranged parallel to it. The two ends of the rotating teeth mesh with a first gear plate and a second gear plate, respectively. One end of each of the first gear plate and the second gear plate is connected to an upper panel and a lower panel.

[0010] Furthermore, the upper and lower panels are connected to sliding grooves along the length of the inner wall of the conical hopper. As the second motor starts, the output shaft of the second motor drives the roller to rotate. At the same time, the output power of the second motor is transmitted to the rotating teeth and drives the upper and lower panels to perform reciprocating back-and-forth translational movements, thereby completing the quantitative control of pollen and discharging it into the guide pipe.

[0011] Furthermore, the first rotating shaft is symmetrically arranged around the center of the housing and correspondingly connected to the center of the ventilation hole. The first conveyor belts are staggered, and a filter screen placed on the inner wall of the housing is embedded between the bracket and the blade. A cleaning component is installed at the front end of the filter screen.

[0012] Furthermore, the cleaning assembly includes a cleaning brush fixed on a first rotating shaft. One end of the cleaning brush is adhesively fixed to a brush plate near the filter screen. As the first motor starts, the blades rotate and form a conveying airflow in the guide tube. At the same time, the brush plate cleans the outer wall of the filter screen under the action of the first rotating shaft.

[0013] Furthermore, the first rotating shafts rotate in the same direction, and the outer wall of the first rotating shaft is provided with a positioning ring fixed on the bracket, and one end of the cleaning brush is provided with a docking groove, which is connected to the docking part on the first rotating shaft by insertion.

[0014] Furthermore, the bottom of the feed tube is provided with a support portion installed on the inner wall of the housing.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, by setting a baffle assembly in the material guiding mechanism, continuous primary quantitative conveying of materials can be achieved, preventing excessive accumulation in the pipeline and thus preventing blockage. In addition, the baffle assembly is also equipped with a baffle plate. By rotating the baffle plate, a quantitative area for pollen is created, thus completing the secondary quantitative conveying of pollen. This effectively controls and conveys pollen quantitatively and prevents blockage of pollen in the conveying pipeline. Furthermore, the primary quantitative conveying mechanism and the secondary quantitative conveying mechanism are integrated, which is reasonably designed, has strong linkage, reduces production costs, and improves work efficiency.

[0016] 2. This invention uses a fan mechanism to transport pollen by air. By setting a filter screen at the ventilation hole, particulate impurities in the outside air can be filtered out. At the same time, a cleaning component is provided on the filter screen to further prevent impurities from adhering to the filter screen. Moreover, the cleaning component can be synchronously driven with the fan component. That is to say, when the air transport is carried out, the corresponding impurity filtration and cleaning work can also be carried out. In addition, the bidirectional setting of the first rotating shaft can increase the contact surface of air transport. The co-rotation of both can also ensure the normal transport of pollen, thereby improving the stability of the device operation.

[0017] 3. The baffles in the discharge pipe, together with the guide channel, can make pollen contact with rice on a larger scale and evenly. The fan-shaped design of the discharge pipe itself can also pollinate rice quickly, efficiently and on a large scale, and can significantly reduce the labor intensity and labor cost in the pollination work.

[0021] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] According to an embodiment of the present invention, a pollination device for large-scale rice seed production is provided.

[0023] Reference manual attached Figure 1 Large-scale rice seed pollination equipment, including: The housing 1 and the feeding mechanism 2 are installed on the conical hopper 3 at the top of the housing 1, and the feeding mechanism 2 is used for quantitative control and conveying of pollen. The fan mechanism 4 includes ventilation holes 5 located on both sides of the front end of the housing 1. A first rotating shaft 7 is movably mounted on the inner wall of the ventilation hole 5 via a bracket 6. One end of the first rotating shaft 7 is connected to the output shaft of the first motor 8 via a first conveyor belt 9, and the other end extends to the blade 10. When the fan mechanism 4 is working, an airflow is formed in the guide pipe 11 to transport pollen. The guide pipe 11 is Y-shaped and connected to the bottom of the guide mechanism 2. A discharge pipe 12 is fixedly connected to one end of the guide pipe 11 away from the ventilation hole 5. The discharge pipe 12 is fan-shaped, and a partition 13 is installed on the inner wall of the discharge pipe 12 via a crossbeam. A guide groove 14 is formed between the partitions 13 and placed inside the discharge pipe 12.

[0024] The conical hopper 3 on the feeding mechanism 2 is fixed to the housing 1. The conical hopper 3 can greatly expand the contact surface with the pollen, thereby preventing the pollen from falling to the outside. At the same time, when the equipment is working, the pollen is continuously poured into the conical hopper 3. Through the operation of the feeding mechanism 2, the primary quantitative conveying and secondary quantitative conveying of pollen can be realized. The pollen is conveyed in an orderly manner by controlling the weight. At the same time, the pollen that has completed quantitative control can automatically slide into the feeding tube 11 due to its own weight, thereby completing the pollination work through the feeding component.

[0025] The bottom of the housing 1 is equipped with rollers at multiple locations, which can be rotated by a driver to achieve automatic pollination over a large area. The housing 1 can also be equipped with a cover plate with pin holes, which can be connected to an external drive device. This allows the drive device to assist in its movement and reach the designated position. The pipeline can be equipped with corresponding sensors to measure the pollen content of the sprayed pollen. The speed of the airflow or the ratio of pollen raw materials in the conical hopper 3 can be controlled and adjusted through the electronic screen on the housing 1.

[0026] like Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the material guiding mechanism 2 includes a second motor 15 placed on a conical hopper 3. The output shaft of the second motor 15 extends to a roller 16 inside the conical hopper 3. A ring array of baffles 17 is installed on the roller 16. A quantitative region 18 is formed between the baffles 17 and the inner wall of the conical hopper 3. A baffle assembly 20 is driven to the output shaft of the second motor 15 via a second conveyor belt 19.

[0027] The partition assembly 20 includes a second rotating shaft 21 that is connected to the second conveyor belt 19. One end of the second rotating shaft 21 is fixed to the first bevel gear 22. The outer wall of the first bevel gear 22 meshes with a second bevel gear 24 that is fixed to the third rotating shaft 23. The second bevel gear 24 is equipped with rotating teeth 25 that are parallel to it. The two ends of the rotating teeth 25 mesh with a first gear plate 26 and a second gear plate 27, respectively. One end of the first gear plate 26 and the second gear plate 27 are respectively connected to an upper panel 28 and a lower panel 29.

[0028] Specifically, the upper panel 28 and the lower panel 29 are both connected to sliding grooves along the length of the inner wall of the conical hopper 3. As the second motor 15 starts, the output shaft of the second motor 15 drives the roller 16 to rotate. At the same time, the output power of the second motor 15 is transmitted to the rotating gear 25 and drives the upper panel 28 and the lower panel 29 to perform reciprocating back-and-forth translational movements, thereby completing the quantitative control of pollen and discharging it into the guide pipe 11.

[0029] In this invention, by setting a baffle assembly 20 in the material guiding mechanism 2, the material can be continuously conveyed in a primary quantitative manner, preventing excessive accumulation in the pipeline and thus preventing blockage. In addition, the baffle assembly 20 is also equipped with a baffle plate 17. By rotating the baffle plate 17, a quantitative area 18 for pollen is formed, which can complete the secondary quantitative conveying of pollen, effectively control and convey the pollen quantitatively, and prevent the pollen from being blocked in the conveying pipeline. At the same time, the primary quantitative conveying mechanism and the secondary quantitative conveying mechanism are integrated, which is reasonable in design, has strong linkage, reduces production costs, and improves work efficiency.

[0030] like Figure 5 , Figure 6 and Figure 7 As shown, after the second motor 15 starts, it can simultaneously drive the baffle assembly 20 and the roller 16 through the second conveyor belt 19. The power of the output shaft of the second motor 15 causes the first bevel gear 22 on the second rotating shaft 21 to rotate through the second conveyor belt 19. Then, through the meshing transmission of the gears, the vertical rotational force is converted into the horizontal rotational force, which then drives the rotating teeth 25 fixed on the second bevel gear 24 to move together. Since the rotating teeth 25 are respectively provided with the first gear plate 26 and the second gear plate 27 at both ends, by means of the "coaxial and reverse" principle of the gears, the upper panel 28 and the lower panel 29 connected to the first gear plate 26 and the second gear plate 27 are reciprocated and pulled back and forth. In this way, during the back and forth pushing process, the pollen area formed between the upper panel 28 and the lower panel 29 can be quantitatively conveyed, preventing too much pollen from reaching the pipe and causing blockage between the roller 16 and the inner wall of the conical hopper 3, thereby affecting the quantitative conveying work of the roller 16.

[0031] After the second motor 15 starts, it can not only drive the roller 16 to rotate, but also transmit the force to the upper panel 28 and the lower panel 29, so that the upper panel 28 and the lower panel 29 can perform a back-and-forth reciprocating motion. This allows the primary metering component and the secondary metering component to work synchronously. Moreover, the metering cavity between the upper panel 28 and the lower panel 29 can perform corresponding metering treatment to prevent the amount of pollen in the pipe from accumulating. Furthermore, the size of the metering cavity between the upper panel 28 and the lower panel 29 can be adaptively adjusted according to actual needs. The size of the metering cavity between the two is the primary metering control area. Through the action of the baffle, the amount of pollen poured in can be initially metered.

[0032] During the rotation of the roller 16, the baffle plate 17 forms an annular groove. Therefore, the inner walls of the conical hopper 3 are provided with arc-shaped parts connected to it at both ends. On the one hand, the pollen can be subjected to secondary quantitative processing through the formed quantitative area 18. On the other hand, it can ensure the normal rotation of the baffle plate 17. Moreover, the top of the arc-shaped part is provided with inclined surfaces on both sides, which allows the pollen to automatically slide into the quantitative area 18, preventing the pollen from accumulating on the inner wall of the conical hopper 3 and avoiding resource waste. The primary quantitative conveying component and the secondary quantitative conveying component are synchronously linked and are both powered by the second motor 15. At the same time, if only the quantitative area 18 connected to the roller 16 is set in the conical hopper 3, although the corresponding pollen quantitative processing can be carried out, if the amount of pollen in the pipeline is too large and no pre-quantitative processing is performed, it is very easy for the baffle plate 17 on the roller 16 to become blocked with the inner wall of the pipeline due to excessive pressure during the rotation, which is not conducive to the normal transport of pollen.

[0033] Specifically, the upper panel 28 and the lower panel 29 are connected to the first gear plate 26 and the second gear plate 27 respectively. The upper panel 28 and the lower panel 29 move synchronously in opposite directions. At the same time, the groove on the conical hopper 3 not only provides the corresponding moving track, but also provides the corresponding support force to ensure the normal movement of the upper panel 28 and the lower panel 29.

[0034] like Figure 3 and Figure 4 As shown, the first rotating shaft 7 is symmetrically arranged around the center of the housing 1 and is correspondingly connected to the center of the ventilation hole 5. The first conveyor belts 9 are staggered, and a filter screen 30 is embedded between the bracket 6 and the blade 10 and placed on the inner wall of the housing 1. A cleaning component 31 is installed at the front end of the filter screen 30.

[0035] The cleaning assembly 31 includes a cleaning brush 32 fixed on the first rotating shaft 7. One end of the cleaning brush 32 is attached to a brush plate near the filter screen 30. As the first motor 8 starts, the blades 10 rotate and form a conveying airflow in the guide tube 11. At the same time, the brush plate cleans the outer wall of the filter screen 30 under the action of the first rotating shaft 7.

[0036] The first rotating shafts 7 rotate in the same direction, and the outer wall of the first rotating shaft 7 is provided with a positioning ring 33 fixed on the bracket 6. The cleaning brush 32 has a docking groove at one end, which is connected to the docking part on the first rotating shaft 7 by plugging. The bottom of the guide tube 11 is provided with a support part 34 installed on the inner wall of the housing 1.

[0037] The symmetrical arrangement of the ventilation holes 5 on the housing 1 can make good use of the contact area at the front end of the housing 1, so as to make full contact with the guide tube 11 and ensure that the pollen can be effectively transported by the force of the wind. The Y-shaped arrangement of the guide tube 11 itself can also converge the air volume, and the air volume and direction of the two are set in the same direction, which can expand the air volume and ensure the effective flow and transport of pollen. In addition, the positioning ring 33 on the bracket can provide corresponding support force for the first rotating shaft 7 during rotation and prevent position deviation during rotation. At the same time, a cleaning component 31 is fixedly installed on the first rotating shaft 7, and the cleaning brush 32 can remove the impurities attached to the filter screen 30, thereby ensuring the cleanliness of the filter screen 30 surface.

[0038] In addition, using the fan mechanism 4 to guide and transport pollen is also one of the technical solutions of this patent. However, after working for a long time, due to the outdoor field environment and the poor air quality with a lot of floating particles, even if a filter screen 30 is set up for filtration and separation, particles will inevitably adhere to the filter screen 30, thus affecting the normal delivery of the wind. The docking part on the first rotating shaft 7 is fixedly installed with the docking groove of the cleaning brush 32 by plugging, so that the first rotating shaft 7 can directly clean the filter screen 30 during rotation, thus ensuring that the filter screen 30 can maintain good cleanliness even during long-term use. Moreover, the structural components are connected in a detachable manner, which makes it easy for personnel to disassemble and repair the structural components when they are damaged.

[0039] like Figure 3 and Figure 8As shown, a ring array of baffles 17 is installed on the drum 16. A quantitative region 18 is formed between the baffles 17 and the inner wall of the conical hopper 3. The baffles 17 connected to the drum 16 is the corresponding secondary quantitative control component. During the rotation of the drum 16, the quantitative region 18 can be rotated continuously, thereby quantitatively processing and discharging the pollen in the quantitative region 18, and then discharging it into the feed pipe 11 through the pipe.

[0040] Specifically, the output shaft of the second motor 15 and the protruding shaft of the drum 16 are fixed by a coupling, which can ensure the stability of the transmission and the transmission force can be effectively transmitted to the drum 16. The inner wall of the conical hopper 3 is also provided with a sealing ring connected to the drum 16, which can ensure the sealing of the structural connection and prevent pollen from leaking to the outside of the conical hopper 3.

[0041] This invention uses a fan mechanism 4 to transport pollen by air. By setting a filter 30 at the ventilation hole 5, particulate impurities in the outside air can be filtered out. At the same time, a cleaning component 31 is provided on the filter 30 to further prevent impurities from adhering to the filter 30. Moreover, the cleaning component 31 can be driven synchronously with the fan assembly. That is to say, when the air transport is carried out, the corresponding impurity filtration and cleaning work can also be carried out. In addition, the bidirectional symmetrical arrangement of the first rotating shaft 7 can increase the contact surface of air transport. The co-rotation of both can also ensure the normal transport of pollen, thereby improving the stability of the device.

[0042] like Figure 1 and Figure 3 As shown, the baffle 13 in the discharge pipe 12, together with the guide channel 14, can make pollen come into contact with rice on a larger scale and evenly. The fan-shaped setting of the discharge pipe 12 itself can also pollinate rice quickly, efficiently and on a large scale, and can significantly reduce the labor intensity and labor cost in the pollination work.

[0043] Under the action of the fan assembly, the pollen that has been quantitatively processed can be transported into the discharge pipe 12 by the wind. The guide channel 14 formed by the baffles 13 in the discharge pipe 12 can achieve uniform spraying of pollen, which facilitates subsequent rice pollination. The crossbeams on the inner wall of the discharge pipe 12 provide corresponding support to the multiple baffles 13. The multiple baffles 13 are equidistant from each other, which can form multiple guide channels 14 of the same size. Moreover, under the action of the wind, large-scale pollination can be achieved, freeing up manpower. The equipment is also equipped with a corresponding roller mechanism, which allows the equipment to reach the corresponding indicated position point.
