Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and more specifically, to a novel cabbage-digging trolley. Background Technology

[0002] In modern agricultural production, the improvement of agricultural mechanization and automation is of great significance for increasing agricultural production efficiency and reducing labor intensity. However, my country's agricultural modernization process is still relatively lagging behind, especially in areas dominated by small-scale farmers, where agricultural production efficiency is low, labor productivity is only 25.3% of that of non-agricultural industries, and problems such as low comparative benefits in agriculture and insufficient international competitiveness of agricultural products are particularly prominent. One of the root causes of these problems is the lack of agricultural mechanization and automation, especially in vegetable planting and harvesting, where the penetration rate of mechanized equipment is low, seriously restricting the modernization of agricultural production.

[0003] Chinese cabbage, the most widely cultivated vegetable crop in my country, accounts for approximately 15% of the country's total vegetable planting area annually, generating over 60 billion yuan in output value, making it a crucial component of my country's agricultural production. However, due to the small arable land area, dense rural population, and numerous terraced fields in southeastern my country, large-scale agricultural machinery cannot be used for the harvesting and collection of Chinese cabbage. Currently, most small-scale farmers still rely on manual labor for harvesting and transporting Chinese cabbage, a method that is not only inefficient but also labor-intensive, failing to meet the demands of modern, high-efficiency agricultural production. Therefore, developing a portable, economical, and efficient Chinese cabbage harvesting device suitable for small-scale farmers has become an urgent problem to be solved. Utility Model Content

[0004] This utility model provides a novel cabbage-digging cart, which aims to improve the technical problems of low efficiency, high labor intensity, and inability to meet the needs of small-scale farmers when manually digging cabbage.

[0005] To solve the above-mentioned technical problems, this utility model provides a novel cabbage-digging trolley, including a frame and a drive unit, a transmission mechanism, a digging mechanism, and a collection device mounted on the frame. The frame has a groove for mounting the collection device. The digging mechanism includes a first turntable and a second turntable rotatably mounted at the front end of the frame, and a plurality of cutter holders connected between the first and second turntables. The end of each cutter holder away from the cutter head is hinged to the first turntable, and the middle portion of the cutter holder is hinged to the second turntable. The axes of the first and second turntables are staggered. The drive unit is connected to the digging mechanism via the transmission mechanism. When the digging mechanism is running, the cutter holders can rotate and simultaneously extend / retract relative to the frame, enabling the cutter head to dig the cabbage.

[0006] As a further optimization, the axis of the second turntable is located in front of the axis of the first turntable; the distance between the connection end of the first turntable and the tool holder and the axis of the first turntable is greater than the distance between the connection end of the second turntable and the tool holder and the axis of the second turntable.

[0007] As a further optimization, the collecting device is located behind the excavating mechanism, and the collecting port of the collecting device faces upward.

[0008] As a further optimization, the front end of the frame is provided with a slot, the first turntable is rotatably connected to one side of the slot, and the second turntable is rotatably connected to the other side of the slot; the slot is provided vertically so that the tool holder can pass through the slot when it rotates.

[0009] As a further optimization, the second turntable includes a turntable portion and a connecting handle, the connecting handle being detachably mounted between the turntable portion and the tool holder.

[0010] As a further optimization, the tool holder includes a tool handle and two cutting heads, with the tool handle arranged in a T-shape; the two cutting heads are mounted on both sides of the front end of the tool handle.

[0011] As a further optimization, the cutter head is arranged in an arc shape.

[0012] As a further optimization, the front end of the cutter head is provided with a limiting part, and the distance between the limiting parts of the two cutter heads gradually decreases towards the head end.

[0013] As a further optimization, the frame is also provided with wheels and a handle, the wheels being located in the middle of the bottom end of the frame, and the handle being located on the side of the frame away from the excavating mechanism.

[0014] As a further optimization, the transmission mechanism includes a reduction gear set, a transmission chain, and a transmission gear. The transmission gear is coaxially connected to the first turntable. The drive unit is connected to the input end of the reduction gear set, and the transmission chain is connected between the output end of the reduction gear set and the transmission gear.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0016] This application provides a novel cabbage-digging cart, comprising a frame, a drive unit, a transmission mechanism, a digging mechanism, and a collection device. The digging mechanism employs a double-crank structure, with the cutter head rotating and retracting simultaneously to ensure the cutter head can penetrate the soil at its lowest point to complete the digging action, and retract at its highest point to transport the cabbage, thereby improving digging efficiency. A single-wheel design forms a lever, allowing for stepless adjustment of the digging depth by raising or lowering the handle end, adapting to different terrains and planting environments. High-strength materials and an optimized transmission system ensure stable operation of the equipment in complex terrain. The integrated design of digging, transporting, and collecting simplifies the operation process and reduces labor intensity. Furthermore, this invention has a simple structure and low cost, making it suitable for small-scale farmers and possessing broad application prospects. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] This utility model provides a novel cabbage-digging cart, the specific implementation of which is described in conjunction with the accompanying drawings. Figure 1 To be continued Figure 4 Please provide a detailed explanation.

[0025] The novel cabbage-digging trolley in this embodiment includes a frame 1, a drive unit 2, a transmission mechanism 3, a digging mechanism 4, and a collection device 5. The technical solution of this utility model will be fully described below in conjunction with the specific structure of each component and their working principle.

[0026] Preferably, the frame 1, as the main load-bearing structure of the entire cart, is made of lightweight, high-strength aluminum profiles and steel. This material selection not only ensures the structural strength of the frame 1 but also reduces the overall weight, facilitating use in complex terrain. The front end of the frame 1 has a through-slot 6, which accommodates the cutter head 12 of the digging mechanism 4, allowing it to smoothly pass through the frame 1 and insert into the soil during rotation to complete the digging operation. A set of wheels 8 is installed at the bottom center of the frame 1, creating a seesaw-like lever. The handle 9 is located on the side of the frame 1 furthest from the digging mechanism 4. By raising or lowering the handle 9, the user can change the relative position between the front end of the frame 1 and the ground, thus achieving stepless adjustment of the digging depth. This design is particularly suitable for planting environments with different terrain conditions, meeting the needs of small-scale farmers for various digging depths.

[0027] Preferably, the digging mechanism 4 is the core component of this utility model. As shown in the attached drawings, the digging mechanism 4 includes a first turntable 10, a second turntable 11, and a plurality of tool holders 12 connected between the first turntable 10 and the second turntable 11. The first turntable 10 and the second turntable 11 are rotatably mounted on the front end of the frame 1 via rotating shafts, and their axes are arranged alternately. The end of the tool holder 12 away from the cutter head 16 is hinged to the first turntable 10, with the connecting end located on the outer periphery of the first turntable 10; the middle part of the tool holder 12 is hinged to the second turntable 11, with the connecting end located on the outer periphery of the second turntable 11, thus forming a double-crank structure for the digging mechanism 4. In this embodiment, specifically, the axis of the first turntable 10 is located behind the axis of the second turntable 11, and the distance from the connecting end of the first turntable 10 and the tool holder 12 to the axis of the first turntable 10 is greater than the distance from the connecting end of the second turntable 11 and the tool holder 12 to the axis of the second turntable 11. This unique geometric layout allows the cutter holder 12 to perform circular motion around the first turntable 10 while simultaneously extending and retracting relative to the frame 1. When the cutter holder 12 rotates to its lowest point, the cutter head 16 extends outward and inserts into the soil to complete the digging action; when the cutter holder 12 rotates to its highest point, the cutter head 16 retracts inward, transporting the dug-up cabbage to the collection device 5. By setting up three sets of cutter holders 12, continuous digging is achieved. This design realizes integrated digging and conveying operations, significantly improving work efficiency.

[0028] The first turntable 10 is an integrated design. According to the number of tool holders 12 to be connected, it extends outward from the center circle to form an appropriate number of extension handles, which is simple in structure and achieves lightweight. The second turntable 11 includes a turntable part 13 and a connecting handle 14. The two ends of the connecting handle 14 are detachably installed between the turntable part 13 and the tool holder 12. One end is fixed to the turntable part 13, and the other end is hinged to the tool holder 12. In this way, the extension and retraction range of the tool holder 12 during the telescopic movement can be adjusted by replacing the connecting handle 14 of different lengths.

[0029] Furthermore, the blade holder 12 includes a T-shaped handle 15 and blade heads 16 mounted on both sides of the front end of the handle 15. The blade heads 16 are arc-shaped to facilitate insertion into the soil and reduce resistance. A limiting part 17 is provided at the front end of the blade head 16, and the distance between the limiting parts 17 on both sides of the blade head 16 gradually decreases towards the front end. This design utilizes the characteristic that cabbage gradually increases in size from bottom to top. During digging, the two blade heads 16 move upwards from the lower sides of the cabbage and are positioned on both sides of the cabbage, while the limiting parts 17 restrict the cabbage to prevent it from falling off from the front end. The blade heads 16 have no enclosed design in the middle, allowing soil and impurities to fall naturally during digging, avoiding accumulation that affects digging efficiency. In addition, the arc-shaped design of the blade heads 16 and the optimized configuration of the limiting parts 17 further improve digging accuracy and reduce damage to the cabbage.

[0030] Preferably, the transmission mechanism 3 is responsible for transmitting power from the drive unit 2 to the digging mechanism 4, ensuring that the digging mechanism 4 receives sufficient power to overcome soil resistance. As shown in the attached figures, the transmission mechanism 3 includes a reduction gear set 18, a transmission chain 19, and a transmission gear 20. The motor of the drive unit 2 is connected to the input end of the reduction gear set 18, which reduces the motor speed and increases the torque. The output end of the reduction gear set 18 is connected to the transmission gear 20 via the transmission chain 19. The transmission gear 20 is coaxially connected to the first turntable 10, transmitting power to the digging mechanism 4. Rotating the first turntable 10 drives the cutter head 12 to rotate and extend. The transmission ratio of the reduction gear set 18 is precisely calculated to ensure that the digging mechanism 4 receives smooth and sufficient power support during operation. The cooperation of the reduction gear set 18, the transmission chain 19, and the transmission gear 20 makes power transmission more stable.

[0031] The collecting device 5, located behind the digging mechanism 4, includes a collecting net. A groove 7 is formed on the frame 1 to accommodate and install the collecting net. The collecting net has a double-layer structure, with one layer being an elastic net and the other a non-elastic net. When the cabbage falls from the digging mechanism 4, the elastic net acts as a buffer, preventing damage from impact; the non-elastic net provides support and fixation, ensuring effective collection. The groove 7 is angled towards the digging mechanism 4, facilitating the cabbage's sliding and minimizing damage. This design fully considers the physical characteristics of the cabbage and the stress during collection, ensuring efficient and reliable collection. When the blade holder 12, carrying the cabbage, rotates above the opening of the collecting net, the blade 16 reverses, causing the cabbage to fall into the collecting net, while the blade 16 retracts to avoid the groove 7.

[0032] The vehicle is equipped with an electronic control system, featuring a simple control circuit system including forward, reverse, and emergency stop buttons. By operating the forward or reverse buttons, drive unit 2 drives the vehicle to move forward or backward. The emergency stop button can quickly cut off the power supply in case of emergencies, ensuring safe and convenient operation. The electronic control system adopts a modular design for easy maintenance and upgrades, and also has overload protection to prevent damage due to excessive load.

[0033] The specific operation process of this utility model is as follows: The user adjusts one side of the lifting handle 9 of the frame 1 according to actual needs, changing the relative position between the front end of the frame 1 and the ground via a lever, thereby adjusting the digging depth. Then, the drive unit 2 is activated, transmitting power to the digging mechanism 4 through the transmission mechanism 3. The first turntable 10 and the second turntable 11 begin to rotate, driving the cutter holder 12 to rotate in a circular motion around the first turntable 10 as the center. Due to the double crank structure, the cutter holder 12 simultaneously exhibits telescopic movement during rotation. When the cutter holder 12 rotates to its lowest point, the cutter head 16 extends outward and inserts into the soil to complete the digging action; after digging, the cutter holder 12 continues to rotate to its highest point, the cutter head 16 retracts inward, and the dug-up cabbage is transported to the collection device 5. The cabbage falls into the collection net, where the elastic net acts as a buffer, and the absence of the elastic net provides support, ensuring effective collection of the cabbage. The user can operate the trolley to move forward or backward using the control buttons to complete the digging of the next cabbage. During operation, in case of an emergency, the user can quickly cut off the power using the emergency stop button to ensure operational safety.

[0034] This invention solves the problem of cabbage easily falling off during digging by designing the shape of the cutter head 16 and the limiting part 17, while also improving digging accuracy. The arc-shaped design of the cutter head 16 facilitates insertion into the soil, and the gradually decreasing spacing of the limiting parts 17 ensures that the cabbage is always held between the cutter heads 16 during digging, preventing it from falling off due to soil resistance or external interference. This design not only improves the success rate of digging but also reduces damage to the cabbage. In addition, the wheels 8, combined with a lever structure, allow for stepless adjustment of the digging depth by raising or lowering the height of one side of the handle 9 on the frame 1, adapting to different terrains and planting environments. The high strength and lightweight materials, along with the efficient transmission system, ensure stable operation of the equipment in complex terrains. The integrated design of digging, transporting, and collecting simplifies the operation process and reduces labor intensity. In summary, this invention provides an efficient, flexible, and reliable cabbage digging trolley, effectively solving the problems in the prior art and possessing broad application value.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
