Description

Technical Field

[0001] This invention relates to the field of cotton topping technology, specifically to a liftable cotton topping machine. Background Technology

[0002] Cotton is a widely cultivated crop, and its fruits are used to make fabrics of different specifications. It is a plant that requires a lot of sunlight. When planting cotton, it is necessary to prune the top to eliminate the apical dominance of the cotton plant, thereby promoting the growth and development of lateral branches and bolls, which is beneficial to improving the yield and quality of cotton.

[0003] Currently, cotton topping is generally done manually or mechanically. Manual topping is slow and costly. Mechanical topping allows for adjusting the topping height or staggering the topping according to the height of the cotton plants, and then cutting off the top of the cotton plants with a cutting device. However, when using mechanical topping, the positions of the toppled cotton plants are not staggered from those of the untoppled cotton plants. When multiple cotton plants of the same height are toppled consecutively, the lateral branches of the previously toppled plants will be cut and damaged when the subsequent cotton plants are toppled, affecting the growth quality and yield of the cotton plants. Summary of the Invention

[0004] The purpose of this invention is to provide a liftable cotton topping machine, which solves the problem that the lateral branches of the topping cotton plants are cut and damaged when multiple cotton plants of the same height on the same path are not staggered during the topping process.

[0005] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0006] A liftable cotton topping machine includes a moving device and a frame mounted on the moving device. The frame is equipped with a lifting device that moves vertically. The end of the lifting device is equipped with a connecting plate that is slidably connected to the frame. The connecting plate is provided with screening devices and multiple cutting devices at equal intervals along the moving direction perpendicular to the moving device. Each cutting device is equipped with a pushing structure for pushing the topped plant to one side. The frame is also equipped with multiple guide channels for the plants pushed to one side by the pushing structure to pass through to the outside of the frame.

[0007] The screening device is used to screen plants according to their different heights and send them to the corresponding cutting device for topping, and the cutting device is used to rotate and cut the top of the plant.

[0008] As a preferred embodiment of the present invention, the screening device includes a plurality of vertical plates equally spaced on the frame along the moving direction of the moving device, each of the vertical plates is provided with a turntable driven to rotate by a driving device, and a plurality of screening plates are uniformly arranged around the rotation center on the periphery of each turntable.

[0009] The center line along the length of the vertical plate is perpendicular to the horizontal plane, the rotation center line of the turntable is parallel to the movement direction of the moving device, and the height of the multiple turntables decreases sequentially in the opposite direction of the movement direction of the moving device. The multiple screening plates are used to follow the rotation of the turntable to push the plant ends of the corresponding height to the cutting device for topping.

[0010] As a preferred embodiment of the present invention, the vertical plate includes an adjusting sleeve connected to the frame. Each adjusting sleeve has a sliding plate slidably connected to it via adjusting bolts. The end of the sliding plate is threadedly connected to the adjusting bolt. The end of the adjusting bolt facing away from the sliding plate is rotatably connected to a connecting plate and extends vertically upward through the connecting plate to the outside.

[0011] As a preferred embodiment of the present invention, the cutting device includes a stepped connecting seat mounted on a frame. Each stepped surface of the connecting seat is provided with a feeding channel for the plants pushed out by the screening plate to enter, and a rotating cutter for topping the plants. The feeding channel is mounted on the frame along a direction perpendicular to the movement of the moving device, and a plurality of the pushing structures are respectively mounted on one side of the corresponding rotating cutter.

[0012] As a preferred embodiment of the present invention, the ejection structure includes a cylindrical seat disposed on the rotating cutter facing the ground, a pressure plate disposed on the periphery of the cylindrical seat, a circulation groove disposed on the connecting seat for the pressure plate to pass through, and the axis of the cylindrical seat is perpendicular to the horizontal plane.

[0013] As a preferred embodiment of the present invention, the pressing plate is provided with a plurality of strip grooves at equal intervals along the axial direction of the cylindrical seat, and the strip grooves are used for the branches and leaves on the side of the plant to enter.

[0014] As a preferred embodiment of the present invention, the side of the pressing plate that contacts the plant and the edge away from the cylindrical base is provided with a rounded chamfer.

[0015] As a preferred embodiment of the present invention, the guide channel includes a guide seat disposed on the frame and connected to the connecting seat. The guide seat is provided with a discharge channel communicating with multiple feed channels, and the discharge channel restricts the relative movement of the plant in a direction parallel to the moving direction of the moving device.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] (1) The present invention uses a moving device to drive the frame to move, so that the cotton continuously enters the cutting device for topping, thus avoiding the problem of high intensity and low efficiency of manual topping.

[0018] (2) The present invention uses a screening device to select plants of similar height to the corresponding area, and then uses a cutting device to top them. At the same time as topping, the plant is pushed to the guide channel by a push-out structure, so that the movement paths of the topped plants and the untopped plants are staggered, thus avoiding the problem of damage to the side branches of the topped plants by the cutting device when topping.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some 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.

[0028] like Figures 1 to 5 As shown, the present invention provides a liftable cotton topping machine, including a moving device and a frame 2 mounted on the moving device. The frame 2 is provided with a lifting device 3 that moves in a vertical direction. The end of the lifting device 3 is provided with a connecting plate 4 that is slidably connected to the frame 2. The connecting plate 4 is provided with screening devices 5 and multiple cutting devices 6 at equal intervals along the moving direction perpendicular to the moving device. Each cutting device 6 is provided with a pushing structure 7 for pushing the topped plant to one side. The frame 2 is also provided with multiple guide channels 8 for the plants pushed to one side by the pushing structure 7 to pass through to the outside of the frame 2.

[0029] The screening device 5 is used to screen plants according to their different heights and send them to the corresponding cutting device 6 for topping, and the cutting device 6 is used to rotate and cut the top of the plant.

[0030] In practical use, the mobile device is used to drive the frame 2 to move between cotton fields. The moving part of the mobile device and the existing cotton topping machine are moved by manual control, which will not be described in detail here.

[0031] The lifting device 3 is used to adjust the height of the connecting plate 4, so that the screening device 5, the cutting device 6, the ejection structure 7, and the guide channel 8 are suitable for cotton plants with different growth conditions.

[0032] When the moving device drives the frame 2, the plant (i.e., cotton) enters the frame 2 in front of the moving device. Since the plants are planted in distinct rows, plants from different rows enter the corresponding screening device 5. The screening device 5 selects multiple groups of plants of roughly the same height and places them in different areas. Then, the cutting device 6 cuts and tops the plants, avoiding the problems of low efficiency and high intensity of manual topping.

[0033] During the cutting process of the cutting device 6, the push-out structure 7 simultaneously contacts the plant and pushes the plant to one side and into the corresponding guide channel 8 while the cutting device 6 is cutting and topping the plant. This makes the positions of the topped plant and the untopped plant staggered, preventing the topped plant from being cut when the cutting device 6 is topping the adjacent plant. This avoids damage to the lateral branches of the topped plant, which would affect its growth and yield.

[0034] In this embodiment, after the screening device 5 selects multiple groups of plants with approximately the same height according to the height of the plants, each group of plants is pushed to different areas and then cut and topped by the cutting device 6. Then, they are pushed into the guide channel 8 through the push-out structure 7 and leave the frame 2 in sequence.

[0035] In this embodiment, the lifting device 3 is a mechanical structure such as a cylinder or hydraulic push rod that performs telescopic movement along a straight line, and the choice is made according to actual needs.

[0036] The screening device 5 includes multiple vertical plates 501 that are equally spaced on the frame 2 along the moving direction of the moving device. Each vertical plate 501 is provided with a turntable 502 that is driven to rotate by a driving device. Multiple screening plates 503 are evenly arranged around the rotation center on the periphery of each turntable 502.

[0037] Among them, the center line along the length direction of the vertical plate 501 is perpendicular to the horizontal plane, the rotation center line of the turntable 502 is parallel to the movement direction of the moving device, and the setting height of the multiple turntables 502 decreases sequentially in the opposite direction of the movement direction of the moving device. The multiple screening plates 503 are used to follow the rotation of the turntable 502 to push the plant end of the corresponding height to the cutting device 6 for topping.

[0038] When the screening device 5 is in use, the driving device, such as a motor, drives the turntable 502 to rotate synchronously with multiple screening plates 503. The screening plates 503 come into contact with a part of the top of the plant, and the rotation of the screening plates 503 moves the top of the plant to the cutting device 6 for cutting and topping.

[0039] The height of the turntables 502 connected by multiple vertical plates 501 decreases sequentially, so that taller plants are first screened and moved to one side by the screening plate 503, while shorter plants are screened and pushed to one side by the screening plate 503 on the adjacent turntables 502 with lower height, and so on, so that the plants on the moving path of the moving device are screened into multiple groups according to their different heights for cutting and topping.

[0040] In this embodiment, the height of the plants screened by the screening plate 503 on the same turntable 502 is a range value. Plants within this range value are all screened and pushed to one side by the screening plate 503 on the same turntable 502 to ensure that all plants can be roughly divided into multiple groups for cutting and topping.

[0041] The vertical plate 501 includes an adjusting sleeve 504 connected to the frame 2. The adjusting sleeve 504 is slidably connected to a slide plate 506 by adjusting bolts 505. The end of the slide plate 506 is threadedly connected to the adjusting bolt 505. The end of the adjusting bolt 505 facing away from the slide plate 506 is rotatably connected to the connecting plate 4 and passes through the connecting plate 4 vertically upward to the outside.

[0042] Considering the different height differences of plants under different growing environments, the corresponding slide plate 506 is driven to move up and down in the adjusting sleeve 504 by rotating the adjusting bolt 505, thereby adjusting the height difference between two adjacent turntables 502, so that the screening plate 503 can better meet the actual needs when screening plants of different heights.

[0043] The cutting device 6 includes a stepped connecting seat 601 mounted on the frame 2. Each stepped surface of the connecting seat 601 is provided with a feeding channel 602 for the plants pushed out by the screening plate 503 to enter, and a rotary cutter 603 for topping the plants. The feeding channel 602 is mounted on the frame 2 along the moving direction perpendicular to the moving device. Multiple pushing structures 7 are respectively mounted on one side of the corresponding rotary cutter 603.

[0044] When the cutting device 6 is in use, the connecting seat 601 provides installation space, the feeding channel 602 allows the plants screened by the screening plate 503 to enter, and the rotating cutter 603 rotates at a constant speed to cut and top the plants that enter the feeding channel 602.

[0045] In this embodiment, the rotating cutter 603 is a structure in which the rotating device drives the cutter to rotate.

[0046] The ejection structure 7 is located on one side of the rotary cutter 603, so that the ejection structure 7 can rotate synchronously with the rotary cutter 603, thereby allowing the plant to be pushed forward by the ejection structure 7 and enter the guide channel 8 when cutting and topping.

[0047] The ejection structure 7 includes a cylindrical seat 701 disposed on the rotating cutter 603 facing the ground. A pressure plate 702 is disposed on the periphery of the cylindrical seat 701. A circulation groove 703 for the pressure plate 702 to pass through is disposed on the connecting seat 601, and the axis of the cylindrical seat 701 is perpendicular to the horizontal plane.

[0048] When the push structure 7 pushes the plant, the cylindrical seat 701 rotates synchronously with the rotating cutter 603, and drives the pressing tablet 702 to move to abut against the plant. The rotation of the rotating cutter 603 pushes the plant forward along the feeding channel 602 and into the guide channel 8.

[0049] Furthermore, during the rotation of the tablet 702, the movement trajectory of the end of the tablet 702 is circular, so that the tablet 702 will automatically detach from the plant after pushing the plant a certain distance into the guide channel 8, thus avoiding the problem of the tablet 702 squeezing the plant and causing damage to the plant.

[0050] The circulation groove 703 allows the tablet 702 to pass through, preventing the tablet 702 and the cylindrical seat 701 from interfering with the connecting seat 601 as they rotate with the rotating cutter 603.

[0051] Multiple strip grooves 704 are evenly spaced along the axis of the cylindrical seat 701 on the tablet 702, and the strip grooves 704 are used for the branches and leaves on the side of the plant to enter.

[0052] By setting multiple strip grooves 704, multiple gaps are provided on the tablet 702 for the lateral branches of the plant to enter, reducing the damage to the lateral branches of the plant when the tablet 702 comes into contact with the plant.

[0053] A rounded chamfer 705 is provided on the side of the tablet 702 that contacts the plant and is away from the edge of the cylindrical base 701.

[0054] The rounded chamfer 705 prevents the sharp edges of the tablet 702 from damaging the plant when it separates from the plant.

[0055] The guide channel 8 includes a guide seat 801 disposed on the frame 2 and connected to the connecting seat 601. The guide seat 801 is provided with a discharge channel 802 that communicates with multiple feed channels 602, and the discharge channel 802 restricts the plant from moving relative to the direction parallel to the moving direction of the moving device.

[0056] When the plants enter the guide channel 8, they first enter the discharge channel 802 through the feed channel 602. Multiple plants move in the discharge channel 802 in the order of planting and leave the discharge channel 802 to the outside of the frame 2.

[0057] Furthermore, the direction of the discharge channel 802 is parallel to the direction of movement of the moving device, so as to avoid the plant being tilted and pushed at too large an angle, which would cause damage to the plant.

[0058] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
