Description

Technical Field

[0001] This utility model relates to the field of plant protection technology, and in particular to a pollination device for increasing the yield of bitter gourd in vegetable greenhouses. Background Technology

[0002] Bitter melon, as an important vegetable crop, is widely cultivated in greenhouse agriculture. Efficient and thorough artificial pollination is crucial for improving yield and fruit quality. However, current pollination operations for greenhouse bitter melon face the following main challenges: 1. Traditional pollination generally uses manual pollination, where operators use pollinators or brushes to pollinate each female flower individually. This method is extremely labor-intensive, inefficient, and requires a significant investment of manpower, especially in large-scale greenhouse cultivation. During peak pollination periods, insufficient manpower or operator fatigue can easily lead to missing the optimal pollination opportunity, resulting in a reduced fruit set rate. 2. Bitter gourd vines twine and grow at varying heights and densities, with flowers distributed over a wide area (from low to high). Fixed pollination equipment or simple hand tools are insufficient to reach flowers at different heights and angles. Operators must frequently bend over, stand on tiptoe, or move ladders, which not only increases labor intensity but also poses safety hazards.

[0003] Therefore, this application provides a pollination device to increase the yield of bitter gourd in vegetable greenhouses to meet the demand. Summary of the Invention

[0004] In order to overcome the problems in the background technology, this utility model provides a pollination device to increase the yield of bitter gourd in vegetable greenhouses, which solves the problems of poor operational flexibility and insufficient adaptability of existing bitter gourd pollination devices.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A pollination device for increasing the yield of bitter gourd in vegetable greenhouses mainly includes a base, on which tracked wheels are slidably connected on both sides of the bottom to adapt to different ground environments inside the greenhouse. A rotating mechanism, which is fixed to one side of the upper surface of the base, is used to achieve multi-angle pollination adjustment; A pollination mechanism is detachably connected to the top of a rotating mechanism, and a push-pull handle is integrally formed on the side of the base away from the rotating mechanism. The pollination mechanism includes a rotating rod, a pollination support column, a sliding groove, a top cover, a hydraulic lifting assembly, a pollination spraying branch pipe, a bottom pollination nozzle, and an end pollination nozzle. The bottom of the pollination support column is coaxially fixed to the rotating rod, and the bottom of the rotating rod is drivenly connected to the top of the rotating mechanism. The outer surface of the pollination support column has four sets of centrally symmetrical sliding grooves, and the top of the pollination support column is fixed to the top with bolts. The hydraulic lifting assembly is built into the pollination support column, and the four corners of the hydraulic lifting assembly are symmetrically fixed to the pollination spraying branch pipe. The bottom of the pollination spraying branch pipe is provided with several bottom pollination nozzles along its length, and the outer end of the pollination spraying branch pipe away from the pollination support column is fitted with an end pollination nozzle.

[0006] Preferably, the hydraulic lifting assembly includes a hydraulic cylinder, a hydraulic rod, a connecting shaft, and a fixing pin; the hydraulic cylinder is fixed to the bottom of the inner cavity of the pollination support column by a bracket, and the output end of the hydraulic cylinder is coaxially fixed to one end of the hydraulic rod; the connecting shaft is uniformly fixed around the outer wall of the hydraulic rod in the circumferential direction, and the fixing pin is integrally formed on the outer wall of the connecting shaft away from the hydraulic rod.

[0007] Preferably, the pollination spraying branch pipe has a pin hole adapted to the fixing pin at one end near the pollination support column. The fixing pin is interference-fitted into the pin hole to realize the detachable connection between the pollination spraying branch pipe and the hydraulic lifting assembly.

[0008] Preferably, a flexible pollen delivery pipe is connected through the bottom side wall of the pollination support column, the output end of the pollen delivery pipe is connected to the input end of the two sets of pollination spraying branch pipes at the upper end through a T-connector, and a pressure-resistant protective sleeve is provided on the outside of the pollen delivery pipe.

[0009] Preferably, a lifting guide groove is provided on the inner end of the pollination support column along the height direction. The size of the lifting guide groove is adapted to the outer size of the hydraulic lifting component, and the hydraulic lifting component can slide up and down along the inner wall of the lifting guide groove.

[0010] Preferably, the rotating mechanism includes a support plate, a drive motor, a transmission rod, a drive wheel, a belt, a driven wheel, and a deep groove ball bearing; the support plate has an L-shaped structure, with its horizontal section fixed to the upper surface of the base by expansion bolts, and the top of the vertical section fixed to the drive motor by bolts; the output end of the drive motor is coaxially fixed to one end of the transmission rod, and the other end of the transmission rod is fixedly fitted with the drive wheel; one side of the drive wheel is connected to the driven wheel via a belt drive, and the transmission ratio between the drive wheel and the driven wheel is 1:2; the rotating rod passes through the driven wheel and is rotatably connected to the top of the base through a deep groove ball bearing.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model achieves mechanized and automated powder spraying operations through an integrated pollination mechanism and a rotating mechanism. Operators no longer need to spray the pollen individually; they only need to push the equipment and control its start and stop to complete large-area pollination work. This greatly liberates labor, freeing workers from heavy and repetitive labor, increasing work efficiency by several times or even dozens of times, effectively solving the problem of insufficient manpower during peak pollination periods, and significantly reducing labor and time costs.

[0012] 2. The pollination mechanism is designed with multiple sets of centrally symmetrically distributed pollination spray branches, each equipped with bottom and end pollination nozzles. This multi-directional, three-dimensional nozzle layout can simulate artificial pollination but more evenly spray pollen mist onto all layers of the bitter gourd plant, ensuring that the flowers (especially female flowers) are fully covered with pollen, greatly reducing missed pollination and uneven pollination. Even and sufficient pollination directly translates into higher fruit set rate, more uniform fruit shape, and a more substantial yield per unit area. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0020] This utility model discloses a pollination device for increasing the yield of bitter gourd in vegetable greenhouses. The pollination device for increasing the yield of bitter gourd in vegetable greenhouses mainly includes a base 1, and tracked wheels 4 are slidably connected to both sides of the bottom of the base 1 to adapt to different ground environments in the greenhouse. Rotation mechanism 3 is fixed to one side of the upper surface of base 1 and is used to achieve multi-angle pollination adjustment. Pollination mechanism 2 is detachably connected to the top of rotating mechanism 3, and a push-pull handle 5 is integrally formed on the side of the base 1 away from rotating mechanism 3. The pollination mechanism 2 includes a rotating rod 201, a pollination support column 208, a sliding groove 203, a top cover 204, a hydraulic lifting assembly, a pollination spray branch pipe 205, a bottom pollination nozzle 206, and an end pollination nozzle 207. The bottom of the pollination support column 208 is coaxially fixed to the rotating rod 201, and the bottom of the rotating rod 201 is drivenly connected to the top of the rotating mechanism 3. The outer surface of the pollination support column 208 has four sets of centrally symmetrical sliding grooves 203, and the top of the pollination support column 208 is fixed to the top of the pollination support column 208 by bolts. The hydraulic lifting assembly has a built-in dry pollination mechanism. Inside the pollen support column 208, and symmetrically fixed at the four corners of the outer side of the hydraulic lifting assembly, are pollination spraying branch pipes 205. Several bottom pollination nozzles 206 are arranged along the length of the bottom of the pollination spraying branch pipes 205, and end pollination nozzles 207 are embedded at the outer end of the pollination spraying branch pipes 205 away from the pollination support column 208. Tracked wheels 4 solve the problem of navigating complex ground conditions inside the greenhouse, ensuring stable and smooth equipment movement and expanding the operating range. The combined use of the rotating mechanism 3 and the pollination mechanism 2 achieves automated pollination operations and multi-angle coverage. The rotating mechanism provides 360° horizontal rotation adjustment, allowing pollination to cover the surrounding plants without moving the equipment itself, greatly increasing the single-point operating range and reducing the frequency of operator movement. The push-pull handle 5 provides excellent ergonomic design, making pushing and operating this relatively heavy equipment effortless and convenient.

[0021] The hydraulic lifting assembly includes a hydraulic cylinder 209, a hydraulic rod 210, a connecting shaft 211, and a fixing pin 212. The hydraulic cylinder 209 is fixed to the bottom of the inner cavity of the pollination support column 208 by a bracket, and the output end of the hydraulic cylinder 209 is coaxially fixed to one end of the hydraulic rod 210. The connecting shaft 211 is uniformly and circumferentially fixed to the outer wall of the hydraulic rod 210, and the fixing pin 212 is integrally formed on the outer wall of the connecting shaft 211 away from the hydraulic rod 210. The hydraulic cylinder 209 and the hydraulic rod 210 provide a strong linear thrust, ensuring that the four pollination spraying branch pipes and their auxiliary components can be raised and lowered simultaneously and smoothly. The operation is stable and the load-bearing capacity is strong. The design of the connecting shaft 211 and the fixing pin 212 efficiently converts the linear motion of the hydraulic rod into a lifting force on the pollination spraying branch pipes. The circumferential fixing method ensures the uniformity and synchronization of force transmission, prevents one-sided jamming, and ensures that the four branch pipes are raised and lowered in a consistent manner.

[0022] The pollination spray branch pipe 205 has a pin hole inside its end near the pollination support column 208, which is adapted to the fixing pin 212. The fixing pin 212 is interference-fitted into the pin hole, realizing the detachable connection between the pollination spray branch pipe 205 and the hydraulic lifting assembly. The interference fit of the fixing pin 212 into the pin hole ensures a firm and reliable connection, which can withstand vibration and a certain degree of torque during operation, ensuring that the connection does not loosen. At the same time, the interference fit also makes disassembly very convenient. The branch pipe can be pulled out without tools or with only simple tools, which facilitates cleaning, replacement, or maintenance of the spray head or branch pipe, greatly reducing the later maintenance costs and time.

[0023] The bottom side wall of the pollination support column 208 is connected to a flexible pollen delivery pipe 202. The output end of the pollen delivery pipe 202 is connected to the input end of the two sets of pollination spray branch pipes 205 at the top through a three-way connector. The pollen delivery pipe 202 is also fitted with a pressure-resistant protective sleeve. The flexible pollen delivery pipe 202 is designed to bend freely without breaking or flattening when the pollination mechanism rotates and rises, ensuring smooth airflow. The connection through the three-way connector enables a pollen supply method of one pipe input and multiple pipe distribution, which is simple in structure and reduces the complex entanglement of external pipelines.

[0024] The inner end of the pollination support column 208 is provided with a lifting guide groove along the height direction. The size of the lifting guide groove is adapted to the outer dimensions of the hydraulic lifting component, and the hydraulic lifting component can slide up and down along the inner wall of the lifting guide groove. The lifting guide groove provides a clear movement trajectory for the hydraulic lifting component, effectively preventing it from shaking, deflecting or getting stuck during the lifting process. The size adaptation and sliding connection ensure low friction and high precision of the movement, so that all pollination spraying branch pipes can move synchronously in the vertical direction, thereby ensuring accurate control of the spraying height and avoiding pollen waste or uneven spraying caused by the tilting of the branch pipes.

[0025] The rotating mechanism 3 includes a support plate 302, a drive motor 301, a transmission rod 303, a drive wheel 304, a belt 305, a driven wheel 306, and a deep groove ball bearing 307; the support plate 302 is L-shaped. The structure consists of a horizontal section fixed to the upper surface of the base 1 by expansion bolts, and a drive motor 301 fixed to the top of the vertical section by bolts. The output end of the drive motor 301 is coaxially fixed to one end of the transmission rod 303, and the other end of the transmission rod 303 is fitted with a drive wheel 304. A driven wheel 306 is connected to one side of the drive wheel 304 via a belt 305, and the transmission ratio between the drive wheel 304 and the driven wheel 306 is 1:2. The rotating rod 201 passes through the driven wheel 306 and is rotatably connected to the top of the base 1 via a deep groove ball bearing 307. The L-shaped support plate 302 provides robust support, reliably transmitting the weight and torque of the drive motor to the base, ensuring the machine body is stable and does not tip over during operation. The belt drive 305 and the 1:2 transmission ratio have the advantages of buffering, vibration absorption, and overload protection, and low operating noise. Secondly, the 1:2 transmission ratio is a design that reduces speed and increases torque. It reduces the output speed, making the pollination mechanism rotate more smoothly and controllably, avoiding pollen being blown away or damage to the plant caused by high-speed rotation; at the same time, the increased torque ensures easy start and rotation even under load, and reliable performance.

[0026] Working process: First, the operator pushes the equipment by pushing or pulling the handle 5. The track wheels 4 at the bottom allow it to smoothly cross the uneven ground inside the shed, moving the equipment to the target work area. Next, the hydraulic cylinder 209 of the hydraulic lifting component is activated to push the hydraulic rod 210, which drives the four pollination spraying branch pipes 205 fixed thereon to rise or fall vertically along the slide groove 203 on the pollination support column 208, adjusting the nozzles to the position that best matches the height of the bitter gourd flowers. The drive motor of the rotating mechanism 3... Machine 301 drives the rotating rod 201 and the entire pollination mechanism 2 to rotate horizontally via belt 305, so that the spraying branch pipes 205 are aligned with different positions of the plant to achieve 360° coverage without dead angles. Finally, under the action of the external pneumatic conveying device, the pollen is transported to each pollination spraying branch pipe 205 through the flexible pollen conveying pipe 202, and finally sprayed out in the form of atomization by the evenly distributed bottom pollination nozzles 206 and end pollination nozzles 207, and evenly sprayed onto the bitter gourd flower to complete the pollination.

[0027] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
