Description

Technical Field

[0001] This invention relates to the field of barley breeding and pollination technology, and in particular to a portable precision pollination device for barley breeding. Background Technology

[0002] Barley is an annual herbaceous plant with erect, smooth stems and smooth leaf sheaths, mostly shorter than the internodes or longer than the internodes at the base. It has auricles on both sides of the apex, which clasp each other. The ligule is membranous, and the leaf blades are slightly rough. The spike-like inflorescence turns yellowish-brown or purplish-brown when mature. The spikelets are linear-lanceolate, covered with short hairs, and have an acuminate, awn-like tip. The lemma extends to an awn at the tip and has fine bristles on both sides. The caryopsis easily detaches from the lemma when mature. It is commonly cultivated in the northwestern and southwestern provinces of China. It thrives in cool, high-altitude climates. It is highly cold-hardy, has a short growing season, is high-yielding, early-maturing, and widely adaptable. A search revealed Chinese patent publication number CN104160947A, which discloses a pollination gun. This invention includes a gun body, a handle, and a transparent pollen storage cup located at the lower center of the gun body. A pollen outlet tube is built into the front end of the gun body, with one end extending outside the gun body and the other end extending into the transparent pollen storage cup. An air inlet tube is located inside the handle, with one end extending through the gun body into the transparent pollen storage cup and connected to a pollen generator at its end. The other end extends outside the handle and connects to an air pump. A power switch is located inside the handle, connecting a battery and the air pump via wires. This invention features a compact structure, simple operation, lightweight practicality, and portability, meeting the pollination needs of crops and fruit trees under various conditions. Furthermore, it is easy to operate, has excellent results, and is highly efficient, ensuring a stable pollen output and uniform pollen dispersion, making it suitable for various users. Existing pollination equipment is mostly large or semi-fixed in structure, which is inconvenient to carry. Especially when working in the field, it requires frequent bending over or changing positions, which increases the physical exertion of operators. Traditional devices lack effective vibration or knocking mechanisms, and pollen is prone to clumping or adhering to the inner wall of the container during storage and transportation, resulting in uneven feeding or even blockage, affecting the continuity of pollination. At the same time, the nozzles of existing equipment are mostly fixed angles, which cannot be flexibly adjusted according to the height and orientation of the flower spike, thus limiting the scope and effectiveness of pollination. To address this, a portable precision pollination device for barley breeding is proposed. Summary of the Invention

[0003] In view of this, the present invention provides a portable highland barley breeding precision pollination device to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0004] The technical solution of the present invention is a portable highland barley breeding precision pollination device, comprising: a pollination machine body, a handle fixedly installed at the bottom of the pollination machine body, and a mobile power supply installed inside the handle; The powder-spraying assembly is installed inside the powder-spraying machine body, and a feeding assembly is installed on the top of the powder-spraying machine body. An adjustment assembly is installed inside the powder-spraying machine body on one side of the powder-spraying assembly. The powder spraying assembly includes a connecting pipe fixedly installed inside the pollination machine body, one end of the connecting pipe is connected to a transmission pipe, and one end of the transmission pipe is provided with a filter screen and extends to the top of the pollination machine body. The adjustment assembly includes a nozzle movably installed inside the pollination machine body. One end of the nozzle is connected to a connecting pipe via a corrugated pipe. Linkage rods are fixedly installed on both sides of the nozzle. A top plate is fixedly installed on the top of the linkage rods. An adjustment plate is slidably installed on the inner top of the pollination machine body. A moving block is fixedly installed on the bottom of the adjustment plate. A fitting wheel that mates with the moving block is rotatably installed on the top of the top plate. A threaded sleeve that mates with the thread of the adjustment plate is rotatably installed on the outside of the fitting wheel. The feeding assembly includes a mounting box fixedly installed on the top of the pollinator body. A filling bottle is threadedly installed on the top of the pollinator body. The filter screen is located at the bottom of the filling bottle. A flipping rod is movably installed inside the mounting box. A knocking head is fixedly installed at the top of the flipping rod. The other end of the flipping rod extends to the outside of the mounting box and is fixedly installed with a pressing plate.

[0005] In a further preferred embodiment, the transmission pipe and the connecting pipe are connected by a T-junction, and the top of the T-junction is also connected to an air duct. A transmission pump is installed on the connecting pipe between the connecting pipe and the T-junction. By setting up the transmission pump and the air duct, a stable airflow channel can be formed, which can efficiently draw pollen from the filling bottle and transport it along the pipeline, avoiding pollen deposition and blockage. At the same time, the air duct introduces external air to regulate the airflow pressure, making the pollen spraying more uniform and continuous.

[0006] In a further preferred embodiment, a fixed box is provided on the top of the pollination machine body, and a dustproof net is provided on one side of the fixed box. One end of the air duct extends into the interior of the fixed box and corresponds to the dustproof net. The dustproof net can effectively filter impurities in the air, prevent foreign objects from entering the air duct and transmission system, ensure pollen cleanliness, and extend the service life of the equipment. At the same time, the fixed box provides stable support for the air duct.

[0007] More preferably, the power bank has an installation plate at its bottom, a magnetic ring corresponding to the bottom of the handle on its inner side, a metal ring that mates with the installation plate at the bottom of the handle, and a protective cover on the outside of the handle. The magnetic ring and the metal ring work together to enable quick assembly and disassembly of the power bank and secure attachment, preventing it from loosening and falling off during operation. The protective cover increases grip comfort and anti-slip performance, improving operational safety.

[0008] In a further preferred embodiment, the nozzle is located inside the pollination machine body and is movably installed via a rotating shaft. A sliding rod is fixedly installed on the top of the pollination machine body, and the adjusting plate is slidably installed between the sliding rod and the adjusting plate. A wedge-shaped groove corresponding to the bonding wheel is provided on the inner side of the moving block. The adjusting plate is guided to slide smoothly by the sliding rod. The cooperation between the wedge-shaped groove and the bonding wheel enables the adjusting plate to accurately drive the top plate to rise and fall when it moves horizontally, thereby driving the nozzle to swing around the rotating shaft, realizing stepless adjustment of the nozzle angle and improving the pollination positioning accuracy.

[0009] More preferably, a limiting sleeve is fixedly installed on the outside of the pollination machine body, and the threaded sleeve is rotatably installed on the inner side of the limiting sleeve. A friction sleeve is provided on the outside of the threaded sleeve. The limiting sleeve provides axial constraint for the threaded sleeve to prevent it from moving. The friction sleeve increases the friction force when screwing, which makes it easier for the operator to make fine adjustments, avoids slippage, and ensures that it does not easily rotate on its own after adjustment.

[0010] In a further preferred embodiment, a support frame is movably mounted at the bottom of the linkage rod, and a spring is fixedly mounted at the top of the pollination machine body. The top of the spring is fixedly connected to the bottom of the support frame. The spring always applies an upward elastic force to the support frame, keeping the linkage rod and the nozzle in their initial positions. When the adjusting plate is pressed down, the spring is compressed, and it automatically resets after being released, achieving elastic return of the nozzle angle and simplifying the operation process.

[0011] More preferably, the bottom of the filling bottle is provided with a threaded opening, the top of the pollination machine body is provided with an internal thread that mates with the threaded opening, the front end of the filling bottle is provided with an observation window, and the outside of the filling bottle is provided with anti-slip texture. The threaded connection makes the filling bottle easy to install and remove and ensures a reliable seal, preventing pollen leakage; the observation window allows for real-time monitoring of the remaining pollen in the bottle and timely replenishment; the anti-slip texture increases the friction when twisting, making operation easier.

[0012] In a further preferred embodiment, a pressing rod is movably mounted on one side of the flipping rod. The top of the pressing rod is provided with a roller that cooperates with the inner wall of the mounting box. An elastic component is provided on the outer side of the pressing rod near the flipping rod. When the pressing plate is pressed, the flipping rod drives the striking head to rise, and at the same time, the pressing rod rolls along the inner wall of the mounting box through the roller. The elastic component accumulates energy. When the pressing plate is released, the elastic component releases, causing the striking head to fall rapidly and hit the bottom of the filling bottle, generating vibration to promote pollen to fall, effectively preventing pollen from clumping and clogging the filter screen, and ensuring smooth feeding.

[0013] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions: I. This invention, through the cooperation between the powder spraying component and the feeding component, uses a transfer pump to generate negative pressure to draw pollen from the filling bottle through the filter screen into the transfer pipe. At the same time, the air duct introduces filtered air to form an air-powder flow. In conjunction with the pressing plate driving the knocking head to repeatedly strike the bottom of the filling bottle to generate vibration, it effectively prevents pollen from clumping and clogging the filter screen, achieving continuous and stable powder supply and uniform spraying, and greatly improving pollination efficiency and pollen utilization rate.

[0014] II. This invention utilizes the interplay between a threaded sleeve, an adjusting plate, a wedge-shaped groove, a contact wheel, and a spring in an adjusting assembly. By rotating the threaded sleeve, the adjusting plate is driven to move horizontally along a sliding rod, which in turn drives the contact wheel to roll along the wedge-shaped groove, thereby raising and lowering the top plate. This allows the nozzle to achieve stepless angle adjustment around the rotation axis. Simultaneously, the spring provides elastic restoring force, resulting in a clear operating feel and precise positioning. This invention enables targeted pollination of barley spikes at different heights, significantly improving the accuracy and applicability of pollination.

[0015] Third, by setting up a mobile power supply, mounting plate, magnetic ring and metal ring at the bottom of the handle, the mobile power supply can be quickly disassembled and firmly attached by magnetic attraction, which can prevent it from falling off during operation. At the same time, the protective cover on the outside of the handle increases the grip comfort and anti-slip performance. The overall structure is compact and easy to carry, which meets the portability needs of long-term field work.

[0016] The above overview is for illustrative purposes only and is not intended to be limiting in any way.

[0020] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-7 As shown, this embodiment of the invention provides a portable highland barley breeding precision pollination device, including: a pollination machine body 1, a handle 101 fixedly installed at the bottom of the pollination machine body 1, a mobile power supply 102 installed inside the handle 101, a mounting plate 103 at the bottom of the mobile power supply 102, a magnetic ring 104 corresponding to the bottom of the handle 101 on the inner side of the mounting plate 103, a metal ring cooperating with the mounting plate 103 at the bottom of the handle 101, and a protective cover on the outside of the handle 101; a powder spraying component 2 is installed inside the pollination machine body 1, a feeding component 3 is installed at the top of the pollination machine body 1, and an adjustment component 4 is installed inside the pollination machine body 1 on one side of the powder spraying component 2; The powder spraying assembly 2 includes a connecting pipe 201 fixedly installed inside the pollination machine body 1. One end of the connecting pipe 201 is connected to a transmission pipe 203. One end of the transmission pipe 203 is provided with a filter screen 204 and extends to the top of the pollination machine body 1. The adjustment component 4 includes a nozzle 401 movably installed inside the pollination machine body 1. One end of the nozzle 401 is connected to the connecting pipe 201 through a corrugated pipe 209. Linkage rods 403 are fixedly installed on both sides of the nozzle 401. A top plate 404 is fixedly installed on the top of the linkage rods 403. An adjustment plate 408 is slidably installed on the inner side of the top of the pollination machine body 1. A moving block 406 is fixedly installed on the bottom of the adjustment plate 408. A bonding wheel 405 that cooperates with the moving block 406 is rotatably installed on the top of the top plate 404. A threaded sleeve 410 that is threadedly engaged with the adjustment plate 408 is rotatably installed on the outside of the bonding wheel 405. The feeding assembly 3 includes a mounting box 301 fixedly installed on the top of the pollinator body 1. A filling bottle 302 is threadedly installed on the top of the pollinator body 1. A filter screen 204 is located at the bottom of the filling bottle 302. A flipping rod 307 is movably installed inside the mounting box 301. A knocking head 309 is fixedly installed at the top of the flipping rod 307. The other end of the flipping rod 307 extends to the outside of the mounting box 301 and is fixedly installed with a pressing plate 308.

[0023] In detail, the mobile power supply 102 inside the handle 101 powers the entire device. The powder spraying component 2 uses the negative pressure generated by the transfer pump 202 to draw pollen from the filling bottle 302 through the filter screen 204 into the transfer pipe 203, and then through the connecting pipe 201 and the corrugated pipe 209 to the nozzle 401 for spraying. The adjustment component 4 drives the adjustment plate 408 to move horizontally by rotating the threaded sleeve 410, which drives the bonding wheel 405 to move along the wedge groove 407, thereby pushing the top plate 404 and the linkage rod 403 to swing up and down, so as to achieve precise adjustment of the nozzle 401 angle. The feeding component 3 causes the flipping rod 307 to rotate by pressing the pressing plate 308, which drives the striking head 309 to repeatedly strike the bottom of the filling bottle 302, shaking off the pollen attached to the bottle wall and the filter screen 204, ensuring continuous and stable powder supply. The overall structure is compact, the operation is intuitive, and it significantly improves the accuracy and efficiency of pollination.

[0024] The transmission pipe 203 and the connecting pipe 201 are connected by a three-way pipe 205. The top of the three-way pipe 205 is also connected to an air duct 206. A transmission pump 202 is installed on the connecting pipe 201 between the connecting pipe 201 and the three-way pipe 205. A fixed box 207 is installed on the top of the pollination machine body 1. A dustproof net 208 is installed on one side of the fixed box 207. One end of the air duct 206 extends into the interior of the fixed box 207 and corresponds to the dustproof net 208.

[0025] In detail, after the transfer pump 202 is started, the air is filtered by the dust screen 208 and enters the three-way pipe 205 through the air duct 206. It mixes with the pollen from the transfer pipe 203 to form an air-powder flow, which is then transported to the nozzle 401 through the connecting pipe 201. On the one hand, this ensures clean air intake, and on the other hand, the amount of powder sprayed can be controlled by adjusting the speed of the transfer pump 202 to adapt to different pollination needs. At the same time, the dust screen 208 is easy to clean and maintain, reducing the system failure rate.

[0026] The filling bottle 302 has a threaded opening 305 at its bottom, and the pollination machine body 1 has an internal thread 306 that mates with the threaded opening 305 at its top. The filling bottle 302 has an observation window 303 at its front end, and the filling bottle 302 has anti-slip texture 304 on its exterior. A squeezing rod 310 is movably installed on one side of the flipping rod 307. The top of the squeezing rod 310 has a roller 311 that mates with the inner wall of the mounting box 301. An elastic component is provided on the outer side of the squeezing rod 310 near the flipping rod 307.

[0027] In detail, the filling bottle 302 is screwed and fixed to the top of the pollination machine body 1 through the threaded port 305 and the internal thread 306, which has good sealing performance. The observation window 303 is made of transparent material, allowing the operator to visually check the pollen quantity at any time. The anti-slip texture 304 makes it easy to twist with one hand. The knocking mechanism composed of the flipping rod 307 and the squeezing rod 310 causes the roller 311 on the squeezing rod 310 to roll along the inner wall of the mounting box 301 and compress the elastic component when the pressing plate 308 is pressed. After being released, the elastic component pushes the squeezing rod 310 to reset, causing the flipping rod 307 to rotate quickly. The knocking head 309 violently hits the bottom of the bottle, and the high-frequency vibration generated effectively destroys the bridging and clumping of pollen, ensuring smooth material discharge at the filter screen 204. There is no need for manual tapping of the bottle body, which improves the degree of automation and ease of use.

[0028] The nozzle 401 is located inside the pollinator body 1 and is movably installed via a rotating shaft 402. A sliding rod 409 is fixedly installed on the top of the pollinator body 1. An adjusting plate 408 is slidably installed between the sliding rod 409 and the adjusting plate 408. A wedge groove 407 corresponding to the contact wheel 405 is provided on the inner side of the moving block 406. A limiting sleeve 411 is fixedly installed on the outside of the pollinator body 1. A threaded sleeve 410 is rotatably installed on the inner side of the limiting sleeve 411. A friction sleeve is provided on the outside of the threaded sleeve 410. A support frame 412 is movably installed at the bottom of the linkage rod 403. A spring 413 is fixedly installed on the top of the pollinator body 1. The top of the spring 413 is fixedly connected to the bottom of the support frame 412.

[0029] In detail, the nozzle 401 is hinged to the pollinator body 1 via a rotating shaft 402 and can swing up and down. During adjustment, the operator rotates the threaded sleeve 410 to move it axially along the limiting sleeve 411, which in turn drives the adjusting plate 408 to move along the sliding rod 409. The moving block 406 at the bottom of the adjusting plate 408 is provided with a wedge-shaped groove 407. The contact wheel 405 is embedded in the groove and rolls up and down with the moving block 406, thereby pushing the top plate 404 to rise and fall. The linkage rod 403 then drives the nozzle 401 to deflect around the rotating shaft 402. The support frame 412 and the spring 413 provide pre-tightening force and reset assistance, making the adjustment process clear and accurate in positioning. The adjustment mechanism has a simple structure and a stable transmission ratio, which can achieve precise alignment of flower spikes at different heights, greatly expanding the applicable scenarios of the device.

[0030] In operation, the operator fills the filling bottle 302 with barley pollen and screws it onto the top of the pollination machine 1 through the engagement of the threaded opening 305 and the internal thread 306. After confirming that the amount of pollen is sufficient through the observation window 303, the operator holds the handle 101 and attaches the mobile power supply 102 to the bottom of the handle 101 through the magnetic ring 104. The power is then turned on to power the entire machine. The power switch is pressed, and the transfer pump 202 starts to work. Outside air is filtered by the dustproof net 208 and enters the three-way pipe 205 through the air duct 206, forming a stable airflow. The negative pressure generated by the transfer pump 202 is transmitted to the filter screen 204 through the connecting pipe 201 and the transfer pipe 203, drawing the pollen from the bottom of the filling bottle 302 into the transfer pipe 203. The pollen and airflow mix at the three-way pipe 205, forming a uniform air-powder two-phase flow, which is then transported to the nozzle 401 through the connecting pipe 201 and the corrugated pipe 209.

[0031] If pollen clumps and adheres to the bottle wall or filter screen 204 due to moisture or static charge accumulation, causing poor feed, the operator can intermittently press the pressing plate 308. The pressing plate 308 drives the rotating rod 307 to rotate, causing the striking head 309 to lift upwards. At the same time, the roller 311 on the squeezing rod 310 rolls along the inner wall of the mounting box 301, compressing the elastic component. After releasing the pressing plate 308, the elastic component is released instantly, pushing the squeezing rod 310 to reset. The rotating rod 307 swings back quickly, and the striking head 309 violently hits the bottom of the filling bottle 302. The high-frequency vibration causes the pollen in the bottle to loosen and fall off, smoothly passing through the filter screen 204 and entering the transmission system, ensuring continuous and stable pollen supply.

[0032] Based on the height and orientation of the barley spikes to be pollinated, the operator rotates the threaded sleeve 410. The threaded sleeve 410 moves axially along the limiting sleeve 411, causing the adjusting plate 408 to slide horizontally along the sliding rod 409. The inner side of the moving block 406 at the bottom of the adjusting plate 408 is provided with a wedge-shaped groove 407. The contact wheel 405 is embedded in the groove and rolls up and down with the displacement of the moving block 406, thereby pushing the top plate 404 to rise and fall. The top plate 404 drives the nozzle 401 to swing up and down around the rotating shaft 402 through the linkage rod 403. The spring 413 always applies an upward elastic force to the support frame 412, so that the nozzle 401 has a tendency to return to the center after adjustment, which is convenient for the next operation. By finely rotating the threaded sleeve 410, the elevation angle of the nozzle 401 can be infinitely adjusted to accurately aim at the target spike.

[0033] After the nozzle 401 is aligned with the target flower spike, the air and powder flow is sprayed out from the nozzle 401, evenly covering the surface of the stigma. The operator can adjust the amount of powder sprayed by controlling the start / stop or speed of the transfer pump 202 according to the amount of pollen and the pollination progress, so as to achieve quantitative and directional precise pollination. After completing pollination at one location, the operator can quickly move to the next target and repeat the above steps.

[0034] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
