Abstract
Description
Technical Field
[0001] The invention relates to the technical field of agricultural equipment, and in particular to a cauliflower harvesting damage reduction device. Background Art
[0002] The existing cauliflower harvesting damage reduction device is an important tool to ensure the quality of cauliflower. It is mainly composed of picking parts, a conveying system and a buffer protection structure. The picking parts mostly use flexible mechanical grippers, which are designed after human hands. They can adaptively adjust the gripping force according to the size and shape of the cauliflower, and gently pick the cauliflower from the plant to avoid pedicel breakage and flower ball damage caused by hard pulling. The conveying system connects the picking and collection links, and often uses conveyor belts. There are mostly soft cushions on the surface, which can not only stably carry the cauliflower, but also reduce friction and bumps. The buffer protection structure is distributed at key nodes, such as below the picking port and the transition point during transportation. It has built-in elastic materials such as sponges and rubber. When the cauliflower comes into contact with it, the impact force is effectively reduced. This set of devices works in coordination, controls from the source of picking, throughout the entire transportation process, minimizes the damage to the cauliflower during harvesting, improves the market competitiveness of cauliflower, and increases production and income for growers.
[0003] The existing cauliflower harvesting damage reduction device will still cause cauliflower to be damaged during harvesting when it is installed and used. Although there is a flexible mechanical gripper, it is difficult to accurately adapt the gripper to cauliflowers with special growth forms and different flower heads with different firmness. Local pressure may be too large, resulting in slight dents or scratches on the surface of the flower head. The soft cushion layer on the conveyor belt is prone to wear and deformation after long-term use, not only losing its buffering effect, but also aggravating the bumping of the cauliflower due to the uneven surface. Moreover, the sponge and rubber materials in the buffering protection structure are prone to aging and hardening in high temperature and high humidity outdoor environments, and cannot effectively buffer the impact force. When the cauliflower passes by, especially when it falls quickly at the transition point and hits the protection structure heavily, it will still cause problems such as broken peduncles and loose flower heads of the cauliflower, which will damage the quality of the cauliflower, cause economic losses to the growers, and bring certain adverse effects to people's use process.

[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. In the present invention, the device body is matched with moving wheels, a driver's seat and an operating table, which provides convenient controllability and good maneuverability for the entire harvesting operation. The operator can easily move the device to the cauliflower planting area and accurately issue instructions. Secondly, the cross frame and its attached parts are exquisitely designed. The first sliding groove effectively guides the cut cauliflower to slide to the designated collection area to avoid cauliflower scattering in the field and causing damage or loss, ensuring that the harvesting process is orderly. Moreover, the semi-gear linkage system driven by the first servo motor is even more critical. On the one hand, the gathering plate driven by it moves flexibly in the open groove. , which can gather the cut cauliflower in time to prevent the surface of the cauliflower from being scratched or broken due to collision, rolling, etc., and maintain the integrity of the cauliflower; on the other hand, the coordinated cutting knife accurately cuts the cauliflower stems in the open groove close to the lower surface of the horizontal frame. The incision is smooth and neat, reducing the pulling and damage to the main body of the cauliflower, and retaining the nutrition and taste of the cauliflower to the greatest extent. Finally, the design of the protective barrel and the corresponding through holes ensures the stable operation of the entire structure, avoids interference from debris, ensures the smooth linkage of various components, realizes efficient and low-loss harvesting of cauliflower, and lays a solid foundation for improving the quality and efficiency of the cauliflower industry.
[0017] 2. In the present invention, through the linkage of various components, the clamping distance can be accurately adjusted according to the size of the cauliflower, the cauliflower can be stably fixed, and the cauliflower can be effectively prevented from shaking, tipping over or skin damage during harvesting, thereby retaining the integrity of the cauliflower to the greatest extent. The powerful soil pretreatment system is used in a powerful way. The third servo motor drives the relevant components to operate, and the excavation wall gently loosens the soil at the root of the cauliflower, greatly reducing the resistance to cutting and collecting materials, and avoiding the risk of tearing and damaging the cauliflower due to forced pulling of the roots. In general, this structure reduces harvesting damage in all directions, lays a solid foundation for the cauliflower industry to move towards refinement and intelligence, and helps to harvest cauliflower with high quality and high efficiency.
[0018] 3. In the present invention, the fourth servo motor drives powerfully, the second sliding groove cooperates with the third sliding groove, and with the help of the flexibly rotating second threaded rod and the fixed limit rod, the precise movement of the cross frame is guaranteed, the cutting and collecting structure is seamlessly connected, and the carefully laid out feed port corresponds to the first sliding groove, allowing the cauliflower to smoothly enter the discharge trough. Among them, the fifth servo motor drives the dividing arm to rotate at high speed, and the cauliflower is delivered according to its characteristics. The dividing ports of different sizes meet various needs, and the corresponding receiving bins are accurately classified and stored, which not only eliminates the trouble of manual secondary sorting, but also avoids collision of divided materials, effectively guarantees the quality of cauliflower, and improves the overall harvesting efficiency.
[0019] 4. In the present invention, after the cauliflower is dug and cut, the cutting and collecting structure and the harvesting positioning structure are moved to the upper end of the device body to start an efficient material processing process. The seventh servo motor is the key to starting. It relies on a unique connection design to ensure power transmission, drive the connecting rod and other components to work together, and accurately pull the aggregate shed to collect the cauliflower rhizomes and send them into the mixing barrel. Subsequently, the sixth servo motor drives the stirring rod to rotate at high speed, and the crushing frame powerfully crushes the cauliflower residual leaves, rhizomes and impurities. The filter plate strictly screens and the materials that meet the particle size slide down through the conical groove and the second sliding groove. The first fixed shell and others continue to work together throughout the process to accurately control the material outflow rhythm. The fixed rod stabilizes the structure to ensure the smooth operation of the dispersed structure, smoothly connect the various links of cauliflower harvesting, reduce material processing obstacles, and improve overall operation efficiency.

DETAILED DESCRIPTION
[0043] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0044] Embodiment 1, as Figure 1-Figure 6 As shown, first, the device body 1 provides support and installation foundation for the entire structure, and the moving wheels 103 around the lower side facilitate the movement of the device to the cauliflower planting area. The operator sits on the driver's seat 101 and can control the device and input relevant operation instructions through the operating table 102. When the cauliflower begins to be harvested, the cross frame 21 extends to the side of the cauliflower plant, and its first sliding groove 22 close to the side wall of the device body 1 is used to guide the cut cauliflower to slide to the designated collection area. The first servo motor 25 in the placement block 24 in the rectangular groove 23 is started, driving the half gear 26 at the rotor to rotate, and the first spur gear 27 meshing with the upper part of the half gear 26 rotates accordingly, and the first spur gear 27 drives the first deflection cylinder 28 fixedly connected to its axis to rotate synchronously, and the outer wall of the first deflection cylinder 28 The linkage block 29 moves accordingly, thereby causing the gathering plate 210 fixed at one end of the linkage block 29 to move in the opening groove 214. The gathering plate 210 can gather the cut cauliflower to prevent it from scattering. At the same time, the second spur gear 212 meshing on the lower side of the half gear 26 rotates in the opposite direction. The cutting knife 213 fixedly installed at the axis of the second spur gear 212 is in the opening groove 214, close to the lower surface of the cross frame 21, and performs a cutting action to cut off the cauliflower stems. The protective barrel 211 protects the first spur gear 27, the second spur gear 212 and other components to prevent debris from entering and affecting the operation. The through holes opened at the corresponding positions of the cross frame 21 and the protective barrel 211 ensure that the structural linkage is not hindered. In this way, through the coordinated operation of various components, accurate cutting and efficient material collection of cauliflower are achieved, reducing damage.
[0045] Embodiment 2, as Figure 7-Figure 12As shown, when the cutting and collecting structure 2 is ready to work, the harvesting positioning structure 3 is started synchronously, and the protective barrel 211 serves as a key connecting component. The spur rack 31 fixed on the lower outer wall thereof meshes with the first cylindrical gear 32. When the second servo motor 33 is started and drives the components connected thereto to operate, the first cylindrical gear 32 will roll along the spur rack 31, prompting the sliding frame 34 to slide in the direction limited by the first sliding groove 37 on the lower outer wall of the protective barrel 211. The protective frame 35 on the sliding frame 34 plays a role in protecting the second servo motor 33 and other components. At the same time, the second deflection cylinder 38 is in the first sliding groove 37, and the rotating sleeve 310 on its outer wall can rotate around the cylinder. The deflection block 312 on the inner wall of the rotating sleeve 310 is embedded in the first limiting groove 311 to ensure that the rotating sleeve 310 rotates stably and will not disengage. The first synchronous wheel 313 on the lower side of the rotating sleeve 310 drives the second synchronous wheel 314 to rotate through the transmission belt. The first threaded rod 315 at the axis of the second synchronous wheel 314 rotates accordingly, causing the threaded block 317 to move on its outer wall thread, and the electric telescopic rod 318 at one end of the threaded block 317 pushes the clamping wall 319 to move closer or farther, so as to accurately adjust the clamping distance according to the size of the cauliflower, and achieve stable clamping of the cauliflower stems. In addition, on the positioning frame 320 on the lower side of the positioning seat 36, the third servo motor 321 drives the second cylindrical gear 322 to rotate, driving the rack ring 323 to rotate, and the rack ring 323 is engaged with the third cylindrical gear 324 distributed at equal intervals. The worm 325 at one end of the third cylindrical gear 324 drives the worm wheel 326 to rotate, and the digging wall 327 on the outer wall of the worm wheel 326 rotates accordingly. The digging wall 327 can loosen the soil around the root of the cauliflower, which is convenient for subsequent cutting and collecting. In this way, through the close cooperation of various components, accurate positioning, clamping and root soil pretreatment of the cauliflower are achieved, and the damage to the cauliflower during the harvesting process is effectively reduced.
[0046] Embodiment 2, as Figure 13-14As shown, the device body 1 provides support for the entire structure, and the fourth servo motor 41 is firmly fixed thereon. The installation position close to the upper surface of one side of the cross frame 21 is very critical. When the material distribution process begins, the second sliding groove 42 and the third sliding groove 43 play a guiding and limiting role. The second threaded rod 44 rotates flexibly in the second sliding groove 42 and cooperates with the cross frame 21, and the limiting rod 45 is fixedly installed in the third sliding groove 43, which not only ensures that the cross frame 21 can slide stably, but also limits its degree of freedom, so that its movement is accurate and correct, ensuring the close connection between the cutting and collecting structure 2 and the material distribution adjustment structure 4. The position of the feed port 46 is carefully designed, accurately corresponding to the first sliding groove 22, and is in the movement trajectory of the cross frame 21. The cut cauliflower can smoothly enter the discharge trough 47 from the first sliding trough 22 through the feed port 46. In the discharge trough 47, the fifth servo motor 48 becomes the core power source. The detachable dividing arm 49 at its rotor rotates at high speed under the drive of the motor. According to the size, quality and other characteristics of the cauliflower, the cauliflower is sent to the dividing ports 410 of different sizes. The design of the dividing ports 410 of different sizes is ingenious and can meet the diverse distribution needs. The corresponding collecting bins 411 on the lower side collect various types of cauliflower in an orderly manner to achieve accurate classification and storage, which greatly improves the efficiency of subsequent processing of cauliflower and reduces the tediousness of manual secondary sorting. At the same time, it avoids collision damage to the cauliflower during the dividing process and ensures the quality of the cauliflower.
[0047] Embodiment 2, as Figure 13-Figure 18As shown, after the cauliflower is dug and cut, the cauliflower will be separated from the root part. In this process, the cutting and collecting structure 2 and the harvesting positioning structure 3 will move to the uppermost end of the device body 1 through the material dividing and adjusting structure 4. The seventh servo motor 516 is used as a power source, and its rotor is detachably connected to one end of the connecting rod 512, which ensures the flexibility and maintainability of power transmission. When the motor rotates, it drives the connecting rod 512 to move. Since the two groups of first fixed shells 59, connecting rod 512, and second fixed shells 513 are symmetrically distributed on both sides of the transmission rod 510 and the collection shed 514, the transmission rod 510 is in the middle. The auxiliary block 511 in the middle of the transmission rod 510 rotates stably, and it contacts the lower outer wall of the blocking wall 55 rotatably installed on the outer wall of one side of the mixing barrel 51, and pushes the blocking wall 55 to open. In this process, the connecting rod 512 is unfolded to push the second fixed shell 513, and the collecting shed 514 is pulled to the bottom of the harvesting positioning structure 3 by the second fixed shell 513, which corresponds to the expansion range of the threaded block 317, so that the cut cauliflower roots and stems are collected on the expanded collecting shed 514, and enter the mixing barrel 51 from the collecting shed 514 through the opened blocking wall 55. The sixth servo motor 52 on the upper wall of the body 1 is started, driving the detachable stirring rod 53 at the rotor to rotate at a high speed, and a number of crushing racks 54 evenly distributed on the outer wall of the stirring rod 53 move violently, so as to crush the materials entering the stirring barrel 51, such as the residual leaves, roots, and soil impurities in the process of cauliflower harvesting, so as to make them fine and convenient for subsequent processing. The filter plate 56 fixedly installed on the lower side of the stirring barrel 51 plays a fine screening role. Only materials that meet the specific particle size requirements can pass through the filter plate 56 and enter the conical groove 57 below. The conical groove 57 uses its special shape to guide the materials to The materials converge on one side and then slide down to the next processing step through the second sliding groove 58. At the same time, the first fixed shell 59 and its related components work together to accurately control the outflow rhythm of the materials in the mixing barrel 51 to avoid blockage or uneven dispersion caused by the materials gushing out all at once. The fixed rod 515 is arranged between the two second fixed shells 513 to stabilize the structure and provide auxiliary support, thereby ensuring that the entire dispersion structure 5 runs smoothly, efficiently completing the dispersion, screening and orderly transportation of the materials, reducing the obstacles to the cauliflower harvesting process caused by material accumulation and improper handling, and ensuring the smooth operation of the device as a whole.
[0048] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
