DETAILED DESCRIPTION OF THE EMBODIMENTS
[0025] In order to make the objectives, technical solutions and advantages of the present utility model more clearly understood, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are merely used to explain the present utility model and are not intended to limit the present utility model.
[0026] Embodiment 1, refer to Figure 1 - Figure 2, a multifunctional micro green vegetable tillage harvester provided in this embodiment aims to solve the problem of low harvesting efficiency of micro green vegetables under complex terrain conditions. It includes a traveling mechanism and a harvesting mechanism. The traveling mechanism has a frame 10 and a conveying component. The frame 10 is made of high-strength aluminum alloy material to ensure that the structure is both light and strong to adapt to the complex terrain of mountainous and hilly areas. Two sets of rollers are installed at the bottom of the frame 10, and the rear roller is equipped with an independent motor drive system to ensure that the machine can move forward smoothly on terrains with different slopes. A collection box is installed at the rear end of the frame 10 for collecting the harvested micro green vegetables. The collection box is designed to be detachable for easy dumping and cleaning. Several weighing devices are also provided on the frame 10, which are located below the collection box and are mainly used to measure the weight of the micro green vegetables.
[0027] The conveying component is arranged along the extending direction of the frame 10. Its input end 201 is located at the front end of the frame 10, and the output end 202 is located at the rear end of the frame 10, near the position of the collection box. To adapt to terrain changes, the output end 202 of the conveying component is designed as a structure that can move up and down. Specifically, the input end 201 of the conveying component is rotationally connected to the frame 10. This rotational connection can be achieved by setting a connecting shaft at the input end 201 of the conveying component and corresponding rotating bearings at the front end of the frame 10. The connecting shaft passes through the rotating bearings to realize the rotational connection between the input end 201 and the frame 10, which is suitable for the output end 202 of the conveying component to move up and down relative to the frame 10, so as to compensate for the undulation of the terrain, enabling the equipment to flexibly adjust according to real-time terrain changes, maintaining the stable conveying of micro green vegetables during the harvesting process, and ensuring that the micro green vegetables always maintain the best posture throughout the process from cutting to conveying in farmlands with different heights and inclinations.
[0028] The harvesting mechanism is installed at the front end of the frame 10. The harvesting mechanism has a guiding component 30 and a cutting component 40. The main function of the guiding component 30 is to guide the micro green vegetables into the harvesting area to ensure that the micro green vegetables can be cut by the cutting component 40. The cutting component 40 is arranged below the guiding component 30, between the guiding component 30 and the conveying component. A harvesting area is formed between the guiding component 30 and the cutting component 40, and the micro green vegetables are cut in this area. At least part of the input end 201 of the conveying component extends into the harvesting area to ensure that the cut micro green vegetables can directly fall onto the conveying component, ensuring a smooth process from cutting to conveying of the micro green vegetables and reducing the loss of micro green vegetables during the conveying process.
[0029] During the harvesting operation, the micro green vegetables are guided by the guiding leaves into the harvesting area. After the micro green vegetables enter the harvesting area, they are cut by the cutting component 40. The cut micro green vegetables directly fall onto the input end 201 of the conveying component and then are conveyed to the collection box.
[0030] In this way, the multifunctional micro-tillage and harvesting machine for pakchoi of the present utility model can efficiently complete the processes of guiding, cutting, and conveying pakchoi in a traveling state, ensuring that the pakchoi maintains the best posture throughout the harvesting process, reducing pakchoi losses, and improving the harvesting efficiency.
[0031] Example 2, refer to Figure 3 - Figure 4 , on the basis of the above embodiment, the frame 10 has an adjusting part 101. The adjusting part 101 is arranged on the lower side of the conveying assembly. Along the movement direction of the output end 202 of the conveying assembly, the adjusting part 101 penetrates through the frame 10, and the adjusting part 101 is in rotational threaded cooperation with the frame 10, so that one end of the adjusting part 101 can contact the conveying assembly in an up-and-down rotatable manner.
[0032] In specific implementation, the adjusting part 101 may mainly consist of an adjusting screw rod. The screw rod has an external thread. A threaded hole corresponding to the adjusting screw rod is opened on the frame 10. The adjusting screw rod passes through the threaded hole and is in threaded cooperation with it. An adjusting handle can be equipped on the adjusting screw rod for easy manual operation. By rotating the adjusting part 101, the relative position between it and the frame 10 can be changed, so that one end of the adjusting part 101 can contact the conveying assembly in an up-and-down rotatable manner, ensuring that the output end 202 of the conveying assembly can be adjusted up and down according to the terrain changes. By rotating the adjusting part 101, the output end 202 of the conveying assembly can be moved up and down within a certain range to adapt to terrains of different heights.
[0033] Through this design, the adjusting part 101 can effectively adjust the height of the output end 202 of the conveying assembly, ensuring that crops can smoothly enter the collection box under complex terrain conditions, reducing crop losses, and improving the harvesting efficiency. This adjustment mechanism is simple and reliable, easy to operate, and suitable for the operation requirements under various terrain conditions.
[0034] Example 3, refer to Figure 5 , on the basis of the above embodiment, a chute 102 is opened on the frame 10. Both ends of the chute 102 form a height difference. Slide rods 203 are arranged on both sides of the conveying assembly. At least part of the slide rods 203 is arranged in the chute 102, suitable for the slide rods 203 to move along the extension direction of the chute 102. At least part of the part of the slide rods 203 located outside the chute 102 abuts against the side wall of the chute 102.
[0035] In specific implementation, the chute 102 is opened on the side wall of the frame 10. The chute 102 can be an arc-shaped groove. There is a certain height difference at both ends of the chute 102, that is, one end is higher and the other end is lower. The slide bars 203 are arranged on both sides of the conveying component. There are at least two slide bars 203, located on both sides respectively. The slide bars 203 can be made of materials with a certain rigidity, such as metal or high-strength plastic. At least part of the slide bars 203 is arranged in the chute 102, so that the slide bars 203 can move along the extending direction of the chute 102. The part of the slide bars 203 located outside the chute 102 is at least partially abutted against the side wall of the chute 102 to ensure that the conveying component will not deviate from the predetermined track during the up and down movement. Specifically, a threaded section can be arranged on the part of the slide bars 203 located outside the chute 102, and a nut is sleeved on the threaded section. By rotating the nut, the locking of the slide bars 203 and the chute 102 can be achieved.
[0036] Through this design, the cooperation between the chute 102 and the slide bars 203 enables the conveying component to remain stable under complex terrain conditions, ensuring that crops are not damaged during the harvesting process and improving the harvesting efficiency.
[0037] Example 4, refer to Figure 2 , on the basis of the above embodiment, the guiding component 30 has a rotating part 301. A plurality of guiding blades are arranged on the rotating part 301. The rotating part 301 is erected on the upper side of the conveying component, and both ends of the rotating part 301 are rotationally matched with the frame 10, so that a plurality of guiding blades can be rotated to the upper side of the conveying component to form a conveying area between the conveying component. Among them, the input end 201 of the conveying component penetrates through the conveying area and extends into the harvesting area.
[0038] In specific implementation, the main supporting structure of the rotating part 301 is a main shaft. The main shaft penetrates through the rotating part 301 and is connected to the frame 10 at both ends thereof. The guiding blades are fixed on the rotating part 301, and the number can be adjusted according to needs. The number of guiding blades can be adjusted according to the type and density of crops. The guiding blades can be designed into a shape with a certain curvature to better guide the crops into the harvesting area. Both ends of the rotating part 301 are connected to the frame 10 through bearings. The bearings can be ball bearings or needle bearings to ensure the smooth rotation of the rotating part 301.
[0039] When the machine is moving forward, the crops first come into contact with the guiding blades and generate a reverse force. The rotating part 301 starts to rotate under the action of the reverse force of the crops. The guiding blades guide the crops into the harvesting area to be harvested by the cutting component 40. The harvested crops continue to be driven by the guiding blades into the conveying area.
[0040] Through this design, seamless connection from crop cutting to conveying can be achieved, thereby improving the harvesting efficiency.
[0041] Example 5, refer toFigure 6 On the basis of the above embodiment, the cutting assembly 40 has a driving device 401, a first shearing blade 402 and a second shearing blade 403. The driving device 401 is arranged on the frame 10, and the first shearing blade 402 and the second shearing blade 403 are arranged horizontally in the harvesting area. The plate surfaces of the first shearing blade 402 and the second shearing blade 403 are in sliding contact with each other. The driving device 401 is transmission-connected to the first shearing blade 402 and is suitable for driving the first shearing blade 402 to slide horizontally relative to the second shearing blade 403.
[0042] In a specific implementation, the first shearing blade 402 and the second shearing blade 403 can be serrated shearing blades, which are flat and have sharp serrations on the edges for cutting crops. The first shearing blade 402 and the second shearing blade 403 are arranged horizontally in the harvesting area and are parallel to each other. The second shearing blade 403 can be fixedly mounted on the frame 10 by fasteners such as bolts. The plate surfaces of the first shearing blade 402 and the second shearing blade 403 are in sliding contact with each other. The driving device 401 is arranged on the frame 10 to provide power for the cutting assembly 40. The driving device 401 can be an electric reciprocating motor, and a transmission mechanism such as a connecting rod and a crank can be used to connect the electric reciprocating motor and the first shearing blade 402. After the electric reciprocating motor is started, the reciprocating motion of the output shaft drives the first shearing blade 402 to move back and forth horizontally.
[0043] Through this design, the first shearing blade 402 can be effectively driven to move back and forth laterally, thereby achieving precise cutting of crops and improving harvesting efficiency.
[0044] Example 6, reference Figure 7 On the basis of the above embodiment, the walking mechanism has a micro-tillage component 50, the micro-tillage component 50 has a connecting end, and a plurality of mounting positions 60 are provided on the frame 10. The plurality of mounting positions 60 form a height difference, and the connecting end of the micro-tillage component 50 is selectively assembled on the plurality of mounting positions 60.
[0045] In specific implementation, the micro-tillage component 50 is equipped with tillage parts, such as a plow or a rake, for turning over or loosening the soil. The micro-tillage component 50 can be mechanically driven or hydraulically driven, and the tillage parts are driven by power transmission of the walking mechanism. The mounting position 60 can be designed to be bolt-fixed, and the connecting end of the micro-tillage component 50 is mounted on the mounting position 60 by fasteners such as bolts.
[0046] When the machine is moving, the micro-tillage component 50 follows the machine, and the tillage components contact the ground to turn over or loosen the soil. The connection end of the micro-tillage component 50 is adjusted to the installation position 60 at different heights as needed to change the tillage depth.
[0047] With this design, the micro-tillage component 50 can effectively carry out tillage operations on different terrains, creating good soil conditions for subsequent planting and harvesting.
[0048] Example 7, refer to Figure 8 , on the basis of the above embodiments, the traveling mechanism has a counter 70, the counter 70 is arranged on the frame 10, and the sensing end of the counter 70 faces the output end 202 of the conveying component.
[0049] In specific implementation, the counter 70 is arranged on the frame 10, usually above or on the side of the output end 202 of the conveying component, ensuring that the passing of crops can be accurately detected. The counter 70 is used to record the number of crops sent out by the output end 202 of the conveying component. The main body of the counter 70 generally includes components such as a processor, a memory, and a display panel. The counter 70 can be powered by a built-in battery or by an external power supply. The sensing end of the counter 70 can adopt a photoelectric sensor, an infrared sensor, or a proximity switch, etc. These sensors can detect the passing of crops. When a crop passes through the output end 202 of the conveying component, it will trigger the sensing end of the counter 70. After the sensing end detects the passing of the crop, it sends a signal to the counter 70. After receiving the signal, the counter 70 will record an event of crop passing. The counter 70 continuously records the number of times the crop passes until the harvesting operation ends.
[0050] Example 8, refer to Figure 3 , on the basis of the above embodiments, a transition section 80 is arranged between the input end 201 and the output end 202 of the conveying component. The transition section 80 has an arc surface, and the center of the arc surface is downward.
[0051] In specific implementation, the conveying component can adopt a conveyor belt mechanism. The conveying component includes a support structure, and the support structure can be a frame or a bracket for supporting the conveyor belt. The conveying component can be driven by an electric motor, and the electric motor can be installed on the frame 10 and connected to the conveyor belt through a transmission belt or a chain drive. The transition section 80 can be arranged at the end of the conveyor belt, that is, at a position close to the output end 202. The transition section 80 helps the crops to smoothly transition from the input end 201 to the output end 202, reducing losses during the conveying process. The center of the arc surface is downward, which helps the crops to naturally transition under the action of gravity.
[0052] With this design, the transition section 80 can effectively help the crops to smoothly transition from the input end 201 to the output end 202, reducing losses during the conveying process.
[0053] Working principle:
[0054] When harvesting pakchoi, after the device is started, the motor drives the rollers to make the machine move forward. When the machine moves forward, the crop first contacts the guiding component 30. The guiding blades of the guiding component 30 guide the crop into the harvesting area. After the crop enters the harvesting area, the cutting action of the cutting component 40 starts. The cutting component 40 drives the first cutting blade 402 to slide laterally relative to the second cutting blade 403 through the driving device 401 to achieve the cutting of the crop. The cut crop continues to be driven by the guiding blades into the conveying area. The input end 201 of the conveying component penetrates the conveying area and extends into the harvesting area. The cut crop directly falls onto the conveying component. The crop moves smoothly from the input end 201 to the output end 202 along the conveyor belt of the conveying component. After the crop reaches the output end 202, it is counted by the counter 70 and smoothly transitions to the collection box through the transition section 80.
