Description

Technical Field

[0001] The invention relates to the technical field of harvesting equipment, and in particular to a cyclic harvesting method and harvesting equipment for ramie. Background Art

[0002] Ramie is a perennial herb, and its bark fiber has important textile value. With the development of agricultural mechanization, mechanized harvesting technology has gradually been applied to the ramie industry to improve production efficiency and reduce labor costs. After searching, the Chinese patent publication number CN214508038U discloses a ramie harvester. Although the device uses a spiral feeding rod and a conveyor belt to enable the machine to directly send the ramie to a storage bin for storage after harvesting, and before the harvester enters the field, the harvesting mechanism can be lifted away from the ramie under the action of a hydraulic rod to prevent damage to the ramie. However, after the ramie is collected in the collection bin, the ramie is stored relatively loosely, resulting in a large space occupied by the ramie in the storage bin. When harvesting a large area of ​​ramie, the number of unloading increases, thereby affecting the harvesting efficiency.

[0003] In addition, the existing device cuts the ramie by bringing the ramie into contact with the cutter during the forward movement, but the contact cutting with the cutter may not ensure the smoothness of the cutting, and the uneven cutting edge may cause the fiber quality to deteriorate, affecting the quality of the final product, and causing uneven stubble heights in the cyclic harvesting method.

[0004] To this end, the present invention proposes a ramie cyclic harvesting method and harvesting equipment, aiming to provide a more efficient, more environmentally friendly, and more adaptable ramie harvesting method and equipment to meet the needs of modern agricultural production. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a cyclic harvesting method and harvesting equipment for ramie, which solves the problems in the background art that ramie is loosely stored inside a collecting bin, occupies a large space, and that the prior device uses a cutter for contact cutting, which may result in uneven cutting.

A transition bin is installed on the top of the storage mechanism, and a discharge port is arranged on one side of the transition bin, and the discharge port is connected with the interior of one end of a conveying pipe. A conveyor belt is arranged inside the conveying pipe, and the other end of the conveying pipe is movably connected with a guide plate. Side plates are fixedly installed on both sides of the guide plate by bolts, and a first motor is installed on one side of the side plate by bolts. An auger is mounted on the outside of the output end of the first motor, and the auger is located inside the guide plate. A second motor is installed at one end of the top of the side plate, and a harvesting claw is installed at the output end of the second motor. A cutting mechanism is installed at one end of the guide plate, and the cutting mechanism is used for cutting ramie stalks.

[0008] Preferably, the compression mechanism includes a collecting bin installed inside the main body of the device, a hydraulic cylinder is embedded on the outside of one end of the collecting bin, the hydraulic cylinders are distributed in a straight line with equal intervals, the telescopic ends of the hydraulic cylinders are welded to the surface of the push plate, a rectangular hole is opened at one end of the collecting bin, the cross-section of the push plate is an L-shaped structure, and the top end of the push plate is in sliding contact with the bottom surface of the transition bin, and the compression mechanism drives the push plate to move by the telescopic hydraulic cylinder to achieve the compaction of the ramie inside the collecting bin; the ramie can be compacted evenly and tightly, which significantly improves the space utilization of the collecting bin, reduces the problem of frequent unloading due to insufficient space, and thus improves the continuity and efficiency of the harvesting operation.

[0009] Preferably, the unloading mechanism includes a cylinder, two of which are provided and are distributed on both sides of the device body, one end of the top of the cylinder is rotatably connected to one end of the second connecting shaft, the other end of the second connecting shaft is rotatably connected to the device body, the outside of the telescopic end at the bottom of the cylinder is rotatably connected to one end of the rotating shaft, the other end of the rotating shaft is rotatably connected to both sides of one end of the unloading plate, the other end of the unloading plate is rotatably connected to one end of the bottom of the collecting bin, one end of the unloading plate is rotatably connected to the bottom of the collecting bin, and the other end is rotatably connected to both sides of the rotating shaft.

[0010] Preferably, a hole groove is provided at the bottom of the transition bin, and the hole groove at the bottom of the transition bin is connected to the interior of the collecting bin. The interior of the transition bin has sloped structures on both sides, and one end of the top of the transition bin is an open structure. The sloped structures on both sides of the interior of the transition bin help to guide the ramie to slide smoothly into the hole groove. This design makes full use of the space of the transition bin, reduces the accumulation of ramie inside, and also reduces the difficulty of operation caused by ramie accumulation. The hole groove at the bottom of the transition bin will be closed during the pushing process of the push plate, thereby preventing ramie from falling into the collecting bin.

[0011] Preferably, hydraulic rods are installed on both sides of the device body, one end of the top of the hydraulic rod is rotatably connected to the device body, the outside of the bottom telescopic end of the hydraulic rod is rotatably connected to the side panel, one side of the side panel is welded to one end of the connecting arm, the other end of the connecting arm is rotatably connected to both sides of the device body, the top of the hydraulic rod is rotatably connected to the device body, and the bottom telescopic end is rotatably connected to the side panel. Such a design allows the side panel to move up and down under the push of the hydraulic rod, thereby adjusting the working height of the entire cutting mechanism to adapt to ramie plants of different heights.

The shearing mechanism is realized through the cooperation between the fixed teeth and the movable teeth. This mechanism avoids the problems of fiber damage and uneven cutting that may be caused by traditional cutters, protects the integrity of ramie fibers, and improves the quality of fibers.

[0014] Preferably, the steps are as follows:

[0015] S01. Planting and initial management: Select suitable soil and climatic conditions for planting ramie, and prepare the soil, including deep tillage, basal fertilizer application and weeding; after planting, ensure that the soil is moist to promote seed germination and seedling growth; initial management also includes regular inspection of seedling growth and timely replanting of missing plants;

[0016] S02. Division of cyclic harvesting areas: Ramie plantations are divided into three major areas: early mowing area, normal mowing area, and stubble mowing area; the stubble mowing area is divided into variety 1 area and variety 2 area according to different varieties; this zoning method can extend the harvesting period, achieve seamless connection between the two mowings, and ensure cyclic harvesting;

[0017] S03. Mechanized first harvest: Use automated harvesting equipment for the first harvest; the equipment moves via tracks and uses fixed teeth and movable teeth to cut off the ramie stem; when the ramie stem is stuck between two fixed teeth, the third motor drives the driven wheel to rotate via the transmission wheel and the transmission belt, and then drives the movable teeth to move back and forth via the connecting rod, thereby cutting off the ramie stem;

[0018] S04. Ramie transportation and storage: The cut ramie is sent to the guide plate by the harvesting claws, and the first motor drives the auger to rotate. The rotation of the auger drives the ramie on the guide plate to move to the connection of the conveying pipe, and then is transported to the discharge port through the conveyor belt, and finally falls into the transition bin, and then falls into the collection bin through the bottom of the transition bin for storage;

[0019] S05. Compacting and optimizing storage: During the storage of ramie, the hydraulic cylinder acts on the push plate, causing the push plate to slide and push the ramie inside the collection bin to the other end, compacting the ramie and increasing the storage capacity of the collection bin;

[0020] S06. Multi-round harvesting: By controlling the hydraulic rod to extend and retract, the side plate is driven to move up and down, and the height of the cutting mechanism is adjusted to adapt to the harvesting of ramie at different heights; this method can achieve multi-round harvesting, and after each harvest, the plant height is controlled at 55-100 cm, realizing cyclic harvesting;

[0021] S07. Unloading: When the ramie inside the collecting bin is full, the telescopic end of the cylinder extends downward, driving one end of the unloading plate to move downward, so that the ramie can be poured out through the unloading plate for easy unloading; at the same time, the growth and soil conditions are continuously monitored, and management measures are adjusted to maintain plant health and increase yields; environmental impacts are taken into consideration, and measures are taken to reduce soil erosion, protect biodiversity, and reduce chemical inputs to achieve sustainability in ramie cultivation.

[0022] Preferably, after ramie is harvested, crops that complement the biological characteristics of ramie are selected for crop rotation, such as planting broad beans or astragalus in spring, planting corn in summer, and planting wheat in autumn, so as to maximize land use and balance soil nutrients throughout the year;

[0023] Every year after ramie harvest, deep plowing is carried out to a depth of more than 30 cm to break up the plow bottom layer and increase soil aeration and water permeability; green manure crops, including astragalus or broad beans, are planted in winter to increase the organic matter content of the soil, which can also be used as organic fertilizer after being turned over in spring to increase the nitrogen content in the soil and improve the soil structure;

[0024] During the ramie growing season, tillage and soil cultivation are carried out to thicken the soil around the ramie stumps to protect the ramie root system, reduce the impact of wind damage and drought, and expand the nutritional area of ​​the root system.

[0025] The present invention provides a ramie cyclic harvesting method and harvesting equipment, which have the following beneficial effects:

[0026] (1) A cyclic harvesting method and harvesting equipment for ramie. The scheme provides a push plate driven by a hydraulic cylinder inside the collecting bin. The push plate of the hydraulic cylinder slides during the storage of the ramie, pushing the ramie inside the collecting bin toward the other end to squeeze the ramie, so that the ramie is compacted and the storage volume inside the collecting bin is increased; the compacting function of the ramie is realized; this design enables the ramie to be effectively compacted when stored inside the collecting bin, reducing the gaps between the ramie, thereby improving the space utilization rate inside the collecting bin; this improvement significantly reduces the number of unloading times when harvesting large areas of ramie, improves the overall harvesting efficiency, reduces operating costs, and reduces the time waste caused by frequent unloading.

[0027] (2) This solution realizes a shearing mechanism by cooperating with fixed teeth and movable teeth. This mechanism avoids the fiber damage and uneven cutting problems that may be caused by traditional cutters, protects the integrity of ramie fibers, and improves the quality of fibers. The smooth cutting edge helps in subsequent processing and ensures the quality of the final product. When the ramie stem is inserted between the two fixed teeth, the third motor rotates through the transmission wheel, and the transmission wheel drives the driven wheel to rotate through the transmission belt, so that the driven wheel can drive the movable teeth to reciprocate through the connecting rod. The ramie stem can be cut by the lateral reciprocating movement of the movable teeth. This reciprocating shearing method reduces damage to the ramie stem.

[0028] (3) This solution uses the telescopic control of the hydraulic rod to enable the side plate to move up and down, thereby adjusting the height of the cutting mechanism. This design enables the harvesting equipment to adapt to ramie plants of different heights and achieve precise harvesting. In addition, this adjustment mechanism also helps to maintain the consistency of stubble height during the harvesting cycle, providing a good foundation for the next growth and harvesting. It also reduces damage to the soil structure and helps maintain the ecological balance of the field. Before the ramie harvesting equipment needs to enter the field, the harvesting mechanism can be lifted away from the ramie under the action of the hydraulic rod to prevent damage to the ramie. This design improves the field passability of the equipment and the protection of crops.

[0029] Thus, the problem that the ramie is stored loosely inside the collecting bin, occupies a large space, and the problem that the existing device uses a cutter for contact cutting, which may cause uneven cutting, is solved. BRIEF DESCRIPTION OF THE DRAWINGS
