Description

Technical Field

[0001] This utility model relates to the field of pomelo flower thinning technology, specifically an adjustable pomelo flower thinning device. Background Technology

[0002] In the pomelo cultivation industry, flower thinning is a crucial step in ensuring fruit quality and yield. By removing weak and overly dense flowers, the tree's nutrients can be concentrated on supplying healthy flowers, preventing the fruit from becoming small, less sweet, or experiencing significant fruit drop due to nutrient dispersion. However, the flower thinning devices currently used in pomelo orchards have significant technical deficiencies in terms of adaptability, stability, and ease of operation, making it difficult to meet the needs of refined cultivation.

[0003] Existing flower thinning devices generally lack flexible height and angle adjustment functions, resulting in poor adaptability. During the growth of pomelo trees, the distribution of flower branches exhibits significant differences in height and angle. However, the flower thinning components of traditional devices are mostly fixed structures or can only achieve coarse adjustments in one dimension. For example, some manual flower thinning tools require operators to frequently bend over and stand on tiptoe to adjust their stance in order to reach flower branches at different heights. Although some mechanical flower thinning devices can adjust the height, the angle is fixed. When facing slanted flower branches, the flower thinning components cannot conform to the growth direction of the flower branches, easily leading to situations such as "missing to prune overly dense flowers" or "mistakenly pruning strong flowers," resulting in insufficient flower thinning precision, directly affecting the subsequent fruit quality and reducing work efficiency.

[0004] In view of this, we provide an adjustable flower thinning device for pomelos. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable flower thinning device for pomelos, which solves the problems mentioned in the background art, such as the lack of flexible height and angle adjustment functions in existing flower thinning devices, poor adaptability, and the tendency to "miss the cutting of overly dense flowers" or "mistakenly cut robust flowers".

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable flower thinning device for pomelos, comprising a flower thinning machine with a flower thinning shaft on its outer side; it also includes a movable component for adjusting the height and angle of the flower thinning shaft; and a fixed component for restricting the adjusted flower thinning shaft; the movable component includes: a telescopic cylinder mounted on the top of the flower thinning machine, a sliding frame mounted on the top of the telescopic cylinder, the sliding frame slidably connected to the inside of the flower thinning machine, a drive motor mounted on the bottom of the sliding frame, a movable rod mounted on the output shaft surface of the drive motor, the movable rod rotatably connected to the top of the sliding frame, a flower thinning frame mounted on the surface of the movable rod, the flower thinning shaft rotatably connected to the inner side of the flower thinning frame, a control motor mounted on the bottom of the flower thinning frame, and the flower thinning shaft mounted on the top of the output shaft of the control motor.

[0007] Preferably, a connecting frame is installed on the top of the flower thinning machine, a toothed plate is installed on the inner side of the connecting frame, the movable rod passes through the connecting frame, a fixed plate is installed on the top of the sliding frame, and an insert plate is slidably connected inside the fixed plate, the insert plate being inserted into the surface of the toothed plate.

[0008] Preferably, a fixing spring is installed on the inner side of the insert plate, and the fixing spring is installed inside the fixing plate.

[0009] Preferably, the fixing component includes: a short plate, the short plate being mounted on top of the fixing plate, a limiting plate being rotatably connected to the inner side of the short plate, a limiting strip being installed at the bottom of the limiting plate, and a spiral spring being installed on the outer side of the limiting plate, the spiral spring being mounted on the inner wall of the fixing plate.

[0010] Preferably, a telescopic rod is installed on the top of the connecting frame, a connecting rod is installed on the surface of the telescopic rod, a fixed plate is installed on the outside of the connecting rod, a protective rod is hinged to the inside of the fixed plate, a torsion spring is installed at one end of the protective rod and the torsion spring is installed on the outer wall of the fixed plate, and a stop block is provided at the other end of the protective rod and the stop block is installed on the outer wall of the fixed plate.

[0011] Preferably, a rotating shaft is installed at the top of the movable rod, and a limit rod is installed on the outside of the rotating shaft.

[0012] Preferably, the cross-sections of the insert plate and the limiting strip are triangular, the cross-sections of the inner side of the protective rod and the limiting rod are L-shaped, and a strip groove is provided on the top of the insert plate.

[0013] As can be seen from the above technical solutions, the adjustable flower thinning device for pomelos provided in the embodiments of this specification has at least the following beneficial effects:

[0014] 1. This utility model, through the setting of movable components, activates the telescopic cylinder, pushing the sliding frame to slide upward along the inner wall of the flower thinning machine. The fixed plate drives the insert plate to slide along the toothed plate. The triangular cross-section of the insert plate cooperates with the toothed groove. Under the action of the fixed spring, it automatically engages with the toothed groove every time it rises a certain distance, initially restricting the descent of the sliding frame. After the flower thinning shaft rises to be level with the target flower branch, the cylinder is closed, and the insert plate is fixed at its height to prevent it from falling due to gravity. Then, the drive motor is activated to drive the movable rod and the flower thinning frame to rotate to adjust the angle of the flower thinning shaft, preventing the flower thinning shaft from shifting and causing misalignment of the flower thinning, improving accuracy, ensuring fruit quality, and enhancing the adaptability of the device.

[0015] 2. This utility model, through the setting of fixed components, ensures that after the height of the sliding frame is fixed, the limiting plate rotates around the short plate under the action of the spiral spring, causing the limiting strip to insert into the strip groove of the insert plate. The triangular cross-section of the limiting strip fits tightly with the strip groove, preventing the insert plate from detaching from the toothed plate. Even if the device vibrates, it can ensure the stability of the sliding frame height and prevent the flower axis from accidentally falling and damaging the flower branches. When the movable rod rotates, it drives the rotating shaft and the limiting rod to rotate. The inner side of the L-shaped protective rod is attached to the limiting rod, and the torsion spring makes it tightly abut against the limiting rod. The stop block prevents the protective rod from moving away. The bidirectional limitation ensures that the angle of the movable rod is fixed, preventing the flower thinning axis from shifting due to the resistance of the flower branches, ensuring stable flower thinning, improving fruit quality, and speeding up the process.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1 - Figure 3 As shown, an adjustable flower thinning device for pomelos includes a flower thinning machine 1, and a flower thinning shaft 2 is provided on the outside of the flower thinning machine 1.

[0026] It also includes an active component 3 for adjusting the height and angle of the basting axis 2;

[0027] Fixing component 4 is used to restrict the sparse flower shaft 2 after it has been adjusted;

[0028] First, the active component 3 includes: a telescopic cylinder 31, which is installed on the top of the flower thinning machine 1; a sliding frame 32 is installed on the top of the telescopic cylinder 31, and the sliding frame 32 is slidably connected inside the flower thinning machine 1; a drive motor 33 is installed at the bottom of the sliding frame 32; a movable rod 34 is installed on the surface of the output shaft of the drive motor 33, and the movable rod 34 is rotatably connected to the top of the sliding frame 32; a flower thinning frame 35 is installed on the surface of the movable rod 34; a flower thinning shaft 2 is rotatably connected to the inner side of the flower thinning frame 35; a control motor 36 is installed at the bottom of the flower thinning frame 35; and the flower thinning shaft 2 is installed on the top of the output shaft of the control motor 36. By combining the telescopic cylinder 31 and the sliding frame 32, the piston rod of the telescopic cylinder 31 extends and retracts, pushing the sliding frame 32 to slide up and down along the inner wall of the flower thinning machine 1. This linear power is converted into the height adjustment action of the flower thinning shaft 2, enabling the flower thinning shaft 2 to adapt to pomelo branches of different heights. Through the fixed connection between the output shaft of the drive motor 33 and the movable rod 34, the rotational power of the motor is transmitted to the movable rod 34, causing the movable rod 34 to rotate around the top hinge point of the sliding frame 32. This drives the flower thinning frame 35 to adjust its angle synchronously with the flower thinning shaft 2, solving the problem that the angle of traditional flower thinning components is fixed and cannot fit the tilted flower branches.

[0029] Secondly, a connecting frame 37 is installed on the top of the flower thinning machine 1, and a toothed plate 38 is installed on the inner side of the connecting frame 37. The movable rod 34 passes through the connecting frame 37. A fixed plate 39 is installed on the top of the sliding frame 32. An insert plate 310 is slidably connected inside the fixed plate 39. The insert plate 310 is inserted into the surface of the toothed plate 38. A fixing spring 311 is installed inside the insert plate 310. The fixing spring 311 is installed inside the fixed plate 39. Through the structure of "fixing spring 311 connecting insert plate 310 and inner wall of fixed plate 39", the natural elasticity of fixing spring 311 is used to continuously apply outward pushing force to insert plate 310, ensuring that insert plate 310 is always tightly inserted into the tooth groove of toothed plate 38 when there is no external force intervention, thus enhancing the stability of height locking.

[0030] In this embodiment, by setting up the movable component 3, the telescopic cylinder 31 is activated, pushing the sliding frame 32 to slide up along the inner wall of the flower thinning machine 1. The fixed plate 39 drives the insert plate 310 to slide along the toothed plate 38. The triangular cross section of the insert plate 310 cooperates with the toothed groove. Under the action of the fixed spring 311, it automatically engages with the toothed groove every time it rises a certain distance, initially restricting the descent of the sliding frame 32. After the flower thinning shaft 2 rises to be level with the target flower branch, the cylinder is closed, and the insert plate 310 is fixed at its height to prevent it from falling due to gravity. Then, the drive motor 33 is activated, driving the movable rod 34 and the flower thinning frame 35 to rotate to adjust the angle of the flower thinning shaft 2, preventing the flower thinning shaft 2 from shifting and causing misalignment of the flower thinning, improving accuracy, ensuring the quality of the fruit, and enhancing the adaptability of the device.

[0031] Example 2

[0032] Please see Figure 4 - Figure 5 As shown, the fixing component 4 includes: a short plate 41, which is installed on the top of the fixing plate 39. A limiting plate 42 is rotatably connected to the inner side of the short plate 41. A limiting strip 43 is installed at the bottom of the limiting plate 42. A spiral spring 412 is installed on the outer side of the limiting plate 42. The spiral spring 412 is installed on the inner wall of the fixing plate 39.

[0033] Furthermore, a telescopic rod 44 is installed on the top of the connecting frame 37, a connecting rod 45 is installed on the surface of the telescopic rod 44, a fixed plate 46 is installed on the outside of the connecting rod 45, a protective rod 47 is hinged to the inside of the fixed plate 46, a torsion spring 48 is installed at one end of the protective rod 47 and is installed on the outer wall of the fixed plate 46, and a stop block 49 is provided at the other end of the protective rod 47 and is installed on the outer wall of the fixed plate 46. Through the telescopic movement of the telescopic rod 44, the connecting rod 45 and the fixed plate 46 are moved closer to or away from the movable rod 34, so as to realize the adjustable deployment of the structure.

[0034] Finally, a rotating shaft 410 is installed on the top of the movable rod 34, and a limiting rod 411 is installed on the outside of the rotating shaft 410. Through the fixed connection between the rotating shaft 410 and the movable rod 34, the rotating shaft 410 rotates synchronously with the movable rod 34, thereby driving the limiting rod 411 to adjust the angle synchronously.

[0035] Both the insert plate 310 and the limiting strip 43 have triangular cross-sections. The triangular cross-section of the insert plate 310 reduces the contact area between the insert plate 310 and the toothed groove of the toothed plate 38, lowering the frictional resistance during sliding and allowing the insert plate 310 to slide more smoothly along the surface of the toothed plate 38 and engage in the toothed groove. The triangular cross-section of the limiting strip 43 is adapted to the strip groove 3100 at the top of the insert plate 310, ensuring that the limiting strip 43 can be quickly and accurately inserted into the strip groove 3100, achieving secondary insertion of the insert plate 310. The inner side of the protective rod 47 and the cross-section of the limiting rod 411 are both L-shaped. The top of the insert plate 310 has a strip groove 3100. The inner side of the protective rod 47 and the L-shaped cross-section of the limiting rod 411 are adapted to each other, increasing the contact area between the two and improving the contact effect, avoiding the problem of easy slippage at a single contact point. The strip groove 3100 at the top of the insert plate 310 provides a dedicated slot for the limiting strip 43, further strengthening the locking effect between the insert plate 310 and the toothed plate 38, and preventing the insert plate 310 from accidentally disengaging from the toothed groove.

[0036] In this embodiment, with the setting of the fixing component 4, after the height of the sliding frame 32 is fixed, the limiting plate 42 rotates around the short plate 41 under the action of the spiral spring 412, driving the limiting strip 43 to insert into the strip groove 3100 of the insert plate 310. The triangular cross section of the limiting strip 43 fits tightly with the strip groove 3100, preventing the insert plate 310 from disengaging from the toothed plate 38. Even if the device vibrates, it can ensure the height of the sliding frame 32 is stable, preventing the flower axis 2 from accidentally falling and damaging the flower branches. When the movable rod 34 rotates, it drives the rotating shaft 410 and the limiting rod 411 to rotate. The inner side of the L-shaped protective rod 47 fits against the limiting rod 411, and the torsion spring 48 makes it tightly abut against the limiting rod 411. The stop block 49 prevents the protective rod 47 from moving away. The bidirectional restriction ensures that the angle of the movable rod 34 is fixed, preventing the flower thinning axis 2 from shifting due to the resistance of the flower branches, ensuring the stability of flower thinning, improving fruit quality, and speeding up efficiency.

[0037] This utility model discloses an adjustable flower thinning device for pomelos. In use, the flower thinning machine 1 serves as the main support, and the flower thinning shaft 2 is the flower thinning execution component. The height and angle of the flower thinning shaft 2 are precisely adjusted via the movable component 3, and the adjusted position is stably locked by the fixing component 4, ensuring that the flower thinning shaft 2 can adapt to flower branches of different heights and angles on pomelo trees, efficiently completing the flower thinning operation. When the device is not in use, it is in a standby state: the flower thinning machine 1 is placed on a flat ground or a movable base, and the flower thinning shaft 2 is suspended at its initial position outside the flower thinning machine 1 via the flower thinning frame 35, not in contact with the flower branches; in the movable component 3, the telescopic cylinder 31 is in a retracted state, causing the sliding frame 32 to be located at the lowest point inside the flower thinning machine 1, and the insert plate 310 is fixed by the spring. Under the action of the elastic force of 311, it is inserted into the initial tooth groove of the toothed plate 38 on the inner side of the connecting frame 37, restricting the up and down movement of the sliding frame 32; the drive motor 33 and the control motor 36 are both in the de-energized state, and the movable rod 34, the flower thinning frame 35 and the flower thinning shaft 2 remain stationary; in the fixed assembly 4, under the action of the elastic force of the spiral spring 412, the limiting plate 42 drives the limiting strip 43 to be inserted into the strip groove 3100 at the top of the insert plate 310, and locks the position of the insert plate 310 for the second time; the telescopic rod 44 is in the retracted state, the fixed plate 46 and the protective rod 47 are close to the connecting frame 37, and the protective rod 47 is attached to the fixed plate 46 under the action of the torsion spring 48, and the limiting rod 411 does not contact the protective rod 47. At this time, the flower thinning machine 1 can be pushed to the side of the target pomelo tree to prepare for the flower thinning operation.

[0038] Based on the height and angle differences of the pomelo tree branches, the position of the thinning shaft 2 is adjusted in three steps using the movable component 3 to ensure that the thinning shaft 2 is accurately aligned with the target branch. The telescopic cylinder 31 is activated, and its piston rod extends upward, pushing the sliding frame 32 upward along the inner wall of the thinning machine 1. Simultaneously, the fixed plate 39 at the top of the sliding frame 32 rises, causing the insert plate 310 to slide along the surface of the toothed plate 38. The triangular cross-section of the insert plate 310 engages with the toothed groove of the toothed plate 38. Under the elastic force of the fixed spring 311, it automatically engages with the corresponding toothed groove after rising a certain distance, initially limiting the descent of the sliding frame 32. When the thinning shaft 2 rises to the same height as the target branch, the telescopic cylinder 31 is closed. At this point, the insert plate 310 is stably locked in the toothed groove of the toothed plate 38, ensuring the height of the thinning shaft 2 is fixed and preventing it from falling due to gravity. The drive motor 33 is then activated, and its output shaft drives the movable rod 34 to rotate around the hinge at the top of the sliding frame 32. The contact point rotates; the movable rod 34 passes through the connecting frame 37, and during its rotation, it drives the flower thinning frame 35 on the surface to rotate synchronously. The flower thinning shaft 2 inside the flower thinning frame 35 adjusts its angle accordingly. After the height and angle of the flower thinning shaft 2 are adjusted, the control motor 36 at the bottom of the flower thinning frame 35 is started. The output shaft of the control motor 36 drives the flower thinning shaft 2 to rotate at high speed around the inside of the flower thinning frame 35. This pushes the flower thinning machine 1 so that the rotating flower thinning shaft 2 contacts the target flower branch. The flower thinning shaft 2 cuts off weak and overly dense flowers by rotating, while retaining strong flowers, thus achieving precise flower thinning. If it is necessary to adjust the flower thinning range, the above height and angle adjustment steps can be repeated without moving the entire flower thinning machine 1, which improves the flexibility of operation. By adjusting the height and angle of the flower thinning shaft 2 through the movable component 3, it is possible to prevent the offset of the height and angle of the flower thinning shaft 2 from causing flower thinning misalignment, thereby improving the accuracy of flower thinning, ensuring the quality of fruit trees, and enhancing the adaptability of the device to different planting scenarios.

[0039] After the movable component 3 completes the position adjustment of the flower thinning shaft 2, multiple locking is achieved through the fixing component 4 to prevent the position of the flower thinning shaft 2 from shifting during the flower thinning process. After the height of the sliding frame 32 is fixed, the limiting plate 42 rotates downward around the short plate 41 under the elastic force of the spiral spring 412, causing the limiting strip 43 at the bottom of the limiting plate 42 to insert into the strip groove 3100 at the top of the insert plate 310. The triangular cross section of the limiting strip 43 fits tightly with the strip groove 3100, preventing the insert plate 310 from sliding into the fixed plate 39 and disengaging from the toothed plate 38. Even if the device vibrates slightly during the flower thinning process, the insert plate 310 will not come out of the toothed groove, ensuring the height of the sliding frame 32 is stable and preventing the flower thinning shaft 2 from accidentally falling and damaging the flower branches. The movable rod 34 also rotates when it is in motion. The rotation of the rotating shaft 410 causes the limiting rod 411 to rotate. When the limiting rod 411 rotates, the inner L-shaped side of the protective rod 47 fits against the limiting rod 411, and the torsion spring 48 continuously provides elastic force to keep the protective rod 47 tightly against the limiting rod 411, restricting the limiting rod 411 from rotating around the rotating shaft 410. At the same time, the stop block 49 prevents the protective rod 47 from rotating away from the limiting rod 411, forming a two-way restriction to ensure that the angle of the movable rod 34 is fixed. During the flower thinning process, the flower thinning shaft 2 will not shift in angle due to the resistance of the flower branches, preventing accidental changes in the height and angle of the flower thinning shaft 2 that could damage the flower branches, ensuring the stability of flower thinning, improving fruit quality, and speeding up work efficiency.

[0040] The above embodiments are only used to illustrate the present utility model, and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
