Description

Technical Field

[0001] This application relates to the field of agricultural harvesting machinery technology, and in particular to a harvesting device for planting Chinese cabbage. Background Technology

[0002] Existing Chinese cabbage harvesting equipment (such as CN219478567U) achieves continuous harvesting through a conveyor belt and a cutting blade, but it has significant drawbacks: the harvested Chinese cabbage goes directly into the collection box, and the attached mud and sand cannot be separated, resulting in two major problems: (1) manual secondary sorting is required, which is inefficient and labor-intensive; (2) mud and sand contaminate the surface of the Chinese cabbage, reducing its quality. This utility model aims to solve the above-mentioned technical bottlenecks. Utility Model Content

[0003] This application provides a harvesting device for Chinese cabbage cultivation, which integrates a vibrating screening module into the collection path. Specifically, a partition divides the trough into a collection platform and a discharge chamber. A screening mechanism is installed at the top of the discharge chamber, employing a combination of a screen and a vibrating motor. This eliminates manual sorting and automatically separates the Chinese cabbage from the mud and sand during the collection path, collecting only the Chinese cabbage. This not only increases sorting efficiency but also reduces labor intensity. Furthermore, 60° inclined discharge plates are installed on both sides of the discharge port to accelerate mud and sand discharge, prevent mud and sand accumulation, and ensure continuous operation of the equipment. Additionally, a dust cover is installed above the screening mechanism to effectively reduce dust emissions, optimize the working environment, and improve worker comfort.

[0004] This application provides a harvesting device for planting Chinese cabbage, including a trough. The front end of the trough is provided with two irregularly shaped fixing rods. One of the fixing rods has a support rod 1 at its bottom and a support plate welded to its side wall. The other fixing rod has a support rod 2 installed at its bottom.

[0005] The same conveyor roller 1 is movably provided between two irregularly shaped fixed rods, and the same conveyor roller 2 is movably provided between support rod 1 and support rod 2. The same inclined conveyor belt is installed on the conveyor roller 1 and the conveyor roller 2, and one end of the conveyor roller 1 is connected to a conveyor motor.

[0006] A cutting motor is installed at the top of the support plate. The output shaft of the cutting motor passes through the support plate and is connected to the cutting blade. It is located in front of the low end of the conveyor belt. An adjustable pressing structure is installed near the cutting blade by bolts through a connecting plate.

[0007] The feature is that the interior of the tank is divided into a collection platform and a discharge chamber by a partition. The top of the discharge chamber is equipped with a screening mechanism, which includes a screen, two side guards and two vibrating motors. The two side guards are located on both sides of the screen, and the two vibrating motors are respectively located on the side walls of the two side guards. The bottom of the discharge chamber is equipped with a discharge port, and both sides of the discharge port are auxiliary discharge plates with an inclination angle of 60°.

[0008] A removable dust cover is provided above the screening mechanism. The dust cover is detachably installed on the tank body by means of bolts through the pressure strips on both sides of its bottom.

[0009] Replaceable collection boxes are placed on top of the collection platform;

[0010] Two connecting structures are provided on one side of the tank, and a wheeled support leg is provided at each of the four corners of the bottom of the tank.

[0011] Furthermore, the transport motor is specifically a servo motor.

[0012] Furthermore, the conveyor belt specifically adopts an anti-slip type.

[0013] Furthermore, the cutting blade is specifically a circular cutting blade.

[0014] Furthermore, the power lines for the transport motor, cutting motor, and vibration motor are integrated and equipped with quick-connect connectors.

[0015] Furthermore, the dust cover is made of transparent PC material.

[0016] As can be seen from the above technical solutions, this application provides a harvesting device for planting Chinese cabbage, including a trough. The front end of the trough is provided with two irregularly shaped fixed rods for assembling support rod one, support rod two and support plate with the trough. One of the fixed rods is provided with support rod one at the bottom, which cooperates with support rod two for setting up transport roller two. Support plate is welded to the side wall for setting up the cutting structure (cutting motor, cutting blade and pressing structure). Support rod two is installed at the bottom of the other fixed rod, which cooperates with support rod one for setting up transport roller two.

[0017] The same transport roller 1 is movably installed between two irregularly shaped fixed rods, and the same transport roller 2 is movably installed between support rod 1 and support rod 2. The same inclined transport belt is installed on transport roller 1 and transport roller 2. One end of transport roller 1 is connected to a transport motor. Together, they form a transport mechanism. During the continuous harvesting of the cabbage hearts, the transport motor provides kinetic energy to drive transport roller 1 to rotate. In turn, transport roller 1 drives the transport belt to drive the transport belt, which in turn drives transport roller 2 to rotate, forming a complete transport system. The cabbage hearts that are continuously cut and harvested by the cutting blade are continuously transported from the lower end to the upper end of the transport mechanism, so that the harvested cabbage hearts continuously fall to the screening mechanism.

[0018] A cutting motor with a kinetic energy output structure is installed at the top of the support plate. During the continuous harvesting of the cabbage hearts, it provides kinetic energy support for the cutting operation of the cutting blade. The output shaft of the cutting motor passes through the support plate and is connected to the cutting blade, which is located in front of the lower end of the conveyor belt. It plays a cutting role. Driven by the cutting motor, it rotates at high speed and uses its sharp blade to cut the stem of the cabbage heart that is pressed down by the pressing structure, so that the cabbage heart is separated from the root and falls onto the conveyor belt. An adjustable pressing structure is installed near the cutting blade by bolts through the connecting plate. It plays a guiding and restraining role. When the power mechanism (such as a tractor) pushes the equipment forward, it gathers and presses down the cabbage hearts within the cutting range in sequence and restrains them near the conveyor belt, so that the cutting blade can just pass through the stem of the cabbage heart and cut the stem, so that the cabbage heart is separated from the root and falls onto the conveyor belt.

[0019] Its features include: a partition dividing the interior of the tank into a collection platform and a discharge chamber; a collection platform for placing collection frames; and a discharge chamber equipped with a screening mechanism. The screening mechanism, located at the top of the discharge chamber, performs a screening function, vibrating and screening the rapeseed transported by the conveyor to separate the rapeseed from the accompanying mud and sand. The mud and sand are allowed to pass through the mesh of the screen into the discharge chamber and be discharged from the discharge port. The rapeseed slides down the screen and finally falls into the collection frame. The screening mechanism includes a screen, two side guards, and two vibrators. The motor has two side guards on both sides of the screen to restrain the cabbage heart and prevent it from deviating from the collection path and falling into the field during the screening and separation process of the cabbage heart and the mud and sand attached to the cabbage heart driven by the vibrating motor. The two vibrating motors are respectively located on the side walls of the two side guards. The kinetic energy output structure provides kinetic energy support for the vibration of the screening mechanism. The bottom of the discharge chamber is provided with a discharge port, which is the channel for the mud and sand screened by the screening mechanism to be discharged from the discharge chamber. Both sides of the discharge port are auxiliary discharge plates with an inclination angle of 60° to facilitate the complete discharge of the mud and sand screened by the screening mechanism from the discharge chamber.

[0020] A detachable dust cover is installed above the screening mechanism to prevent dust. During the screening process of separating the cabbage hearts and sand, the dust raised by the screen vibration is suppressed to optimize the working environment and improve the comfort of the workers. The dust cover is detachably installed on the tank body by bolts through the pressure strips on both sides of its bottom, which is convenient for disassembly, cleaning and maintenance of the screening mechanism and other components.

[0021] The top of the collection platform is equipped with replaceable collection frames and containers for collecting continuously harvested cabbage hearts. These frames are replaceable, and when the collection frame is full of cabbage hearts, the full frame and the cabbage hearts inside can be directly placed onto the transport vehicle and replaced with a new collection frame to continue collecting cabbage hearts. This ensures continuous operation of the equipment and enables rapid loading and unloading of cabbage hearts after harvesting, thereby improving the practicality of the equipment.

[0022] Two connecting structures are provided on one side of the trough for connection. When picking the cabbage hearts, they can be detachably connected to the matching connector on the power mechanism (such as a tractor) to achieve the connection between the equipment and the power mechanism (such as a tractor). Each of the four corners of the bottom of the trough is provided with a wheeled support leg to facilitate the movement of the equipment under the drive of the power mechanism (such as a tractor) to achieve continuous automatic picking of the cabbage hearts.

[0023] In summary, the beneficial effects of this application are as follows:

[0024] 1. A screening mechanism is set at the top of the discharge chamber. It adopts a combination of screen and vibrating motor, which eliminates manual sorting and realizes the automatic separation of cabbage hearts and mud and sand in the collection path. It is not only highly efficient, but also less labor-intensive.

[0025] 2. A screening method is adopted, which automatically separates the cabbage from the mud and sand during the collection process. Only the cabbage is collected, avoiding recontamination of the cabbage by the mud and sand and ensuring the quality of the cabbage.

[0026] 3. The two sides of the discharge port are equipped with 60° inclined auxiliary discharge plates, which accelerates the discharge of mud and sand, avoids the accumulation of mud and sand, and ensures the continuous operation of the equipment.

[0027] 4. A dust cover is installed above the screening mechanism, which effectively reduces dust by suppressing dust, optimizes the working environment, and improves the comfort of the staff.

[0028] 5. The collection frame adopts a replaceable design. When the collection frame is full of bok choy, the full collection frame and the bok choy inside can be directly placed on the transport vehicle and replaced with a new collection frame to continue collecting bok choy. This not only ensures the continuous operation of the equipment, but also enables quick loading and unloading of bok choy after harvesting, thus improving the practicality of the equipment.

Detailed Implementation

[0036] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0037] From the above technical solutions, it can be seen that:

[0038] Example 1:

[0039] See Figures 1-4 .

[0040] A harvesting device for Chinese cabbage cultivation includes a trough 1. Two irregularly shaped fixing rods are provided at the front end of the trough 1 for assembling support rod 6, support rod 7 and support plate 10 with the trough 1. Support rod 6 is provided at the bottom of one of the fixing rods, which cooperates with support rod 7 for setting up the second transport roller. Support plate 10 is welded to the side wall for setting up the cutting structure (cutting motor 11, cutting blade 12 and pressing structure 14). Support rod 7 is installed at the bottom of the other fixing rod, which cooperates with support rod 6 for setting up the second transport roller.

[0041] The same transport roller 1 is movably installed between two irregularly shaped fixed rods, and the same transport roller 2 is movably installed between support rod 1 6 and support rod 2 7. The same inclined transport belt 8 is installed on the transport roller 1 and the transport roller 2. One end of the transport roller 1 is connected to the transport motor 9. Together they form a transport mechanism. During the continuous harvesting of the cabbage, the transport motor 9 provides kinetic energy to drive the transport roller 1 to rotate. In turn, the transport roller 1 drives the transport belt 8 to drive the transport roller 2 to rotate, forming a complete transport system. The cabbage that is continuously cut and picked by the cutting knife 12 is continuously transported from the lower end to the upper end of the transport mechanism, so that the picked cabbage continuously falls to the screening mechanism.

[0042] A cutting motor 11 is installed at the top of the support plate 10. This kinetic energy output structure provides kinetic energy support for the cutting operation of the cutting blade 12 during the continuous harvesting of the cabbage hearts. The output shaft of the cutting motor 11 passes through the support plate 10 and is connected to the cutting blade 12. It is located in front of the lower end of the conveyor belt 8 and plays a cutting role. Driven by the cutting motor 11, it rotates at high speed and uses its sharp blade to cut the stem of the cabbage heart that is pressed down by the pressing structure 14, so that the cabbage heart is separated from the root and falls onto the conveyor belt 8. An adjustable pressing structure 14 is installed near the cutting blade 12 by bolts through the connecting plate 13. This structure plays a guiding and restraining role. When the power mechanism (such as a tractor) pushes the equipment forward, the cabbage hearts within the cutting range are successively gathered and pressed down and restrained near the conveyor belt 8, so that the cutting blade 12 can just pass through the cabbage heart stem and cut the cabbage heart stem, so that the cabbage heart is separated from the root and falls onto the conveyor belt 8.

[0043] The feature is that the interior of the tank 1 is divided into a collection platform 4 and a discharge chamber 2 by a partition 5. The collection platform 4 is a structure for placing the collection frame 20. The discharge chamber 2 is a structure with a screening mechanism. The top of the discharge chamber 2 is equipped with a screening mechanism, which plays a screening role. It is used to vibrate and screen the cabbage hearts conveyed by the transport mechanism, so that the cabbage hearts are separated from the mud and sand attached to the cabbage hearts. The mud and sand fall through the mesh of the screen 15 into the discharge chamber 2 and are discharged from the discharge port 3. The cabbage hearts slide down the screen 15 and finally fall into the collection frame 20. The screening mechanism includes a screen 15, two side guards 16 and two vibrators. Motor 17 and two side guards 16 are located on both sides of screen 15 to constrain the cabbage heart and prevent it from deviating from the collection path and falling into the field during the screening and separation process of the cabbage heart and the mud and sand attached to the cabbage heart driven by the vibrating motor 17 to vibrate the screen 15. The two vibrating motors 17 are respectively located on the side walls of the two side guards 16, and the kinetic energy output structure provides kinetic energy support for the vibration of the screening mechanism. The bottom of the discharge chamber 2 is provided with a discharge port 3, which is the channel for the mud and sand screened by the screening mechanism to be discharged from the discharge chamber 2. Both sides of the discharge port 3 are auxiliary discharge plates 23 with an inclination angle of 60°, which facilitates the complete discharge of the mud and sand screened by the screening mechanism from the discharge chamber 2.

[0044] A detachable dust cover 18 is provided above the screening mechanism to prevent dust. During the screening process of the screening mechanism for separating the cabbage heart and mud and sand, the dust raised by the screen vibration is suppressed to optimize the working environment and improve the comfort of the workers. The dust cover 18 is detachably installed on the tank body 1 by bolts through the pressure strips 19 on both sides of its bottom, which is convenient for disassembly, cleaning and maintenance of the screening mechanism and other components.

[0045] The top of the collection platform 4 is equipped with a replaceable collection frame 20, a collection container for collecting continuously harvested cabbage hearts. It is replaceable. When the collection frame is full of cabbage hearts, the full collection frame 20 and the cabbage hearts collected inside can be directly placed on the transport vehicle and replaced with a new collection frame 20 to continue collecting cabbage hearts, so as to ensure the continuous operation of the equipment and realize the quick loading and unloading of cabbage hearts after harvesting, thereby improving the practicality of the equipment.

[0046] Two connecting structures 22 are provided on one side of the trough body 1, which serve as a connection. When picking the cabbage hearts, they can be detachably connected to the matching connector on the power mechanism (such as a tractor) to achieve the connection between the equipment and the power mechanism (such as a tractor). Each of the four corners of the bottom of the trough body 1 is provided with a wheeled support leg 21, which facilitates the movement of the equipment under the drive of the power mechanism (such as a tractor) to achieve continuous automatic picking of the cabbage hearts.

[0047] As a preferred embodiment, the transport motor 9 is specifically a servo motor, which realizes closed-loop control of position, speed and torque, overcomes the problem of stepper motor step loss, has strong overload resistance, can withstand loads three times the rated torque, meets the characteristics of smooth operation of the transport belt 8, and ensures the orderly harvesting and collection of Chinese cabbage.

[0048] As a preferred embodiment, the conveyor belt 8 is specifically an anti-slip conveyor belt, which increases the coefficient of friction and prevents the vegetable stems from slipping, shifting, or even falling during transport, thereby ensuring that each vegetable heart moves along the preset path.

[0049] As a preferred embodiment, the cutting blade 12 is specifically a circular cutting blade, which facilitates continuous cutting of the cabbage heart and stem that have been pressed down by the overturned structure, so as to achieve the purpose of continuously picking the cabbage heart.

[0050] In a preferred embodiment, the power lines of the transport motor 9, the cutting motor 11, and the vibration motor 17 are integrated and equipped with quick-connect sockets, which facilitates the quick assembly and disassembly of the lines when the device is connected to or disconnected from a power vehicle (such as a tractor).

[0051] As a preferred embodiment, the dust cover 18 is made of transparent PC material, which is visible and easy to clean.

[0052] Working principle: When picking the heart of the bok choy:

[0053] (1) Place the collection box 20 on the collection platform 4 and connect the device to the power mechanism (such as a tractor) using the connection structure 22;

[0054] (2) Insert the quick-connect plug into the power supply plug of the power mechanism (such as a tractor) to power on the equipment and make it run.

[0055] (3) The staff drives the power mechanism (such as a tractor) forward, pushing the running equipment to follow it forward, so that the crushing structure 14 successively gathers and crushes the cabbage hearts within the picking range and restrains them near the conveyor belt 8. Then, the cutting blade 12, which is running in motion, cuts the stems of the cabbage hearts crushed by the crushing structure 14 in sequence, so that the cabbage hearts are separated from the roots and fall continuously onto the conveyor belt 8. The running transport mechanism transports the cabbage hearts that fall onto the conveyor belt 8 from the lower end to the upper end of the transport mechanism, so that the cabbage hearts transported to the upper end of the transport mechanism fall onto the screening mechanism in sequence. The vibrating motor 17 drives the screen 15 to vibrate, so that the cabbage hearts that fall onto the screen 15 in sequence slide from the upper end to the lower end during the vibration. In this process, the mud and sand attached to the cabbage hearts are separated from the cabbage hearts, so that the mud and sand pass through the mesh of the screen 15 and finally return to the field from the discharge port 3, so that the cabbage hearts slide down the screen 15 and fall into the collection frame 20.

[0056] (4) When the collection box 20 is full of cabbage, the staff responsible for collection will unload the full collection box 20 and the cabbage collected inside it and place it on the transport vehicle. The empty collection box 20 will be placed on the collection platform 4 to continue collecting and ensure that the equipment can continuously harvest cabbage.
