Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a harvester. Background Art

[0002] my country is the country with the largest carrot planting area in the world, and its total output accounts for about 40% of the world's total carrot planting area. However, most of my country's carrot planting areas mainly rely on manual harvesting, which is labor-intensive and inefficient, seriously affecting the timely harvest of carrots and limiting the scale of my country's carrot industry production.

[0003] At present, the research and development of carrot combine harvesters has formed a system in developed countries, but it is still in the initial stage of research and development and application in my country. my country's large-scale carrot production bases mainly rely on the introduction of advanced foreign carrot harvesting machinery to solve the harvesting problem on the farm. However, there are the following problems: (1) Foreign carrot harvesters are expensive and have high after-sales maintenance costs, which are beyond the purchasing power of farmers; (2) There are differences in agronomy between China and foreign countries, and foreign carrot harvesters are not suitable for the planting requirements of domestic varieties. Therefore, it is of great significance to develop a carrot combine harvester suitable for my country's national conditions, meet production requirements, improve the level of carrot mechanization operations, and increase farmers' income.

[0004] At present, the carrot harvesters independently developed and designed in my country usually have a relatively simple structure, but still have some shortcomings: (1) A guide rod is set at the front end of the conveying mechanism to guide the carrot leaves. The guide rod is fixed and cannot dynamically gather the leaves, resulting in poor guiding effect, which makes it difficult for the conveying mechanism to ensure the clamping effect of the carrots; (2) A fixed fruit blocking plate is set to align the vertical height of the carrots. After the carrots are stuck by the fruit blocking plate, their leaves are still driven by the conveying device to move, and the carrots are prone to getting stuck, resulting in poor alignment effect; (3) The harvester adjusts the frame angle by setting waist-shaped holes and fasteners. The angle position adjustment range is small, the adjustment direction is single, and the retraction and release adjustment efficiency is low; (4) The leaves cut by the harvester may stick to the harvester when thrown out, making subsequent collection and processing difficult, or even fall into the inside of the harvester and affect the normal operation of the harvester.

[0005] Based on this, the existing technology needs to be further improved. Utility Model Content

[0059] In the harvester of the present embodiment, the leaf-pulling device 2 includes a plurality of groups of leaf-pulling teeth 12, which are arranged in a mounting shell 13 and driven by a chain 14 to rotate around the edge of the mounting shell 13 to comb the carrot leaves. The mounting shell 13 is mounted on the first frame 7 through a fixing plate 15. The leaf-pulling teeth 12 include a vertical connecting end and a protruding end, and the connecting end is rotatably connected to the chain 14. A first limiting plate 16 is installed on the inner side of the mounting shell 13, and the connecting end abuts against the first limiting plate 16 to cause the leaf-pulling teeth 12 to rotate, and causes the protruding end to extend to the outside of the mounting shell 13. A second limiting plate 17 is arranged in the mounting shell 13, and the protruding end abuts against the second limiting plate 17 to cause the leaf-pulling teeth 12 to rotate so as to be accommodated inside the mounting shell 13.

[0060] In the harvester of this embodiment, the connecting end includes two spaced-apart and oppositely arranged blocks, which are connected to the chain plates of the chain 14, and a chain channel is formed between the two blocks. The block abuts against the first limit plate 16, and the two can slide relative to each other. The first limit plate 16 is arranged along the extension direction of the chain 14, and one end of the first limit plate 16 is arc-shaped, and the arc shape surrounds the rotating shaft of the driven sprocket supporting the chain 14. Two first limit plates 16 are arranged, and the two first limit plates 16 are spaced and oppositely arranged, and are respectively fixed to the two guard plates of the mounting shell 13. Two second limit plates 17 are arranged, and the two second limit plates 17 are spaced and oppositely arranged, and the second limit plates 17 are arranged along the extension direction of the chain 14.

[0061] The leaf-pulling teeth 12 are arranged to be rotatably connected with the chain 14, and the first limiting plate 16 and the second limiting plate 17 limit the leaf-pulling teeth 12 and make the leaf-pulling teeth 12 rotate on the chain 14 to reach an extended or retracted state, to pull the leaves or to retract them, and the leaves of the carrots are combed and guided from the root to the top leaves by rotating the extended leaf-pulling teeth 12, so that the leaves of the carrots are made as vertical as possible, thereby facilitating the leaf-clamping and conveying device 1 of the harvester to clamp the carrots for conveying, and the connecting ends of the leaf-pulling teeth 12 are rotatably connected to the chain 14 from both sides through blocks, so that the chain 14 is more stably connected to the leaf-pulling teeth 12, and the chain 14 drives the leaf-pulling teeth 12 to run smoothly. At the same time, the chain 14 guides the leaf-pulling teeth 12 to avoid the deflection of the leaf-pulling teeth 12, and ensure the combing effect of the leaf-pulling teeth 12 on the carrot leaves. Preferably, a mounting seat is arranged on the chain plate of the chain 14, and the mounting seat is rotatably connected to the block through a pin shaft.

[0062] The first limit plate 16 is fixed in position, and the chain 14 moves through the gap between the two first limit plates 16. When the blade tooth 12 is driven by the chain 14 to rotate around the mounting shell 13, the stopper at the connecting end abuts against the end of the arc-shaped portion of the first limit plate 16, and then the stopper rotates to drive the blade tooth 12 to rotate on the chain 14, and the protruding end of the blade tooth 12 extends out, and the stopper slides relative to the surface of the first limit plate 16. The first limit plate 16 is installed on the upper side of the mounting shell 13 to realize the blade tooth 12. The leaf teeth 12 are in an extended state on the upper side of the mounting shell 13 and the part in contact with the carrot leaves, thereby effectively guiding the leaves together; two first limit plates 16 are provided, corresponding to the two blocks at the connecting ends of the leaf-pulling teeth 12, so that the two blocks are limited at the same time and drive the leaf-pulling teeth 12 to rotate as a whole, so that the force is evenly distributed, the service life of the leaf-pulling teeth 12 is increased, and the leaf-pulling teeth 12 are ensured to rotate and extend smoothly, while stably maintaining the extended state for leaf-pulling operations, and further guiding the leaf-pulling teeth 12.

[0063] When the blade tooth 12 rotates to the top of the mounting shell 13, the limiting effect of the first limiting plate 16 is lost, and the blade tooth 12 rotates to the right due to its own gravity. Then, when the blade tooth 12 is continued to be driven by the chain 14 to move to the lower side of the active sprocket, the gravity causes the blade tooth 12 to rotate to the left, and the extended end is vertically downward. Then, with the movement of the chain 14, the extended end abuts against the end of the second limiting plate 17, prompting the blade tooth 12 to rotate, and the extended end gradually retracts into the mounting shell 13, so that the blade tooth 12 is in a storage state on the lower side of the mounting shell 13. Since the first frame 7 is below the mounting shell 13, there is no need to extend the blade tooth 12 to actually The above arrangement can play a guiding role, so the above arrangement makes the overall blade-stretching device 2 have a certain height while reducing the space occupied by the installation; two second limit plates 17 are arranged, which are convenient to install and adjust and have a simple structure. At the same time, when in the storage state, the two blocks of the blade-stretching teeth 12 are respectively limited at the right-angle ends, so that the blade-stretching teeth 12 are also uniformly stressed in the storage state, thereby ensuring the stable rotation of the chain 14; preferably, the protruding end is arranged as a shell, and a cavity is formed inside. When in the storage state, it covers the outside of the chain 14, thereby reducing the installation distance between the second limit plate 17 and the chain 14, making the structure more compact and reducing the overall volume of the mounting shell 13.

[0064] It should be noted that the overall length of the second limit plate 17 is determined according to actual conditions to ensure that the protruding end of the blade-smoothing tooth 12 can be smoothly rotated out while abutting against the end of the first limit plate 16, thereby avoiding motion interference between the blade-smoothing tooth 12 and the second limit plate 17 and the first limit plate 16, which would affect normal operation.

[0065] Preferably, a plurality of blade-pulling teeth 12 are provided and are evenly distributed along the chain 14. The top end of the mounting shell 13 is sleeved on the main shaft 18. The main shaft 18 is rotatably connected to the mounting shell 13 and drives the chain 14 to rotate. The first end of the main shaft 18 is connected to the output end of the hydraulic motor through a coupling, and the second end of the main shaft 18 is mounted on the bearing. The hydraulic motor and the bearing are respectively mounted on the first frame 7 of the harvester through the mounting seat 19.

[0070] Two mounting shells 13 are arranged as a group, and the leaf-pulling teeth 12 on both sides gather and guide the carrot leaves in the middle from both sides to the middle, so that the leaves are concentrated, and the gathering and concentration effect is better, thereby improving the efficiency of guiding the leaves, facilitating the clamping and subsequent transportation of the leaf-clamping and conveying device 1, and avoiding unstable clamping. A connecting sleeve 21 is arranged to increase the connection strength of the two mounting shells 13 in the mounting shell group, so that the leaf-pulling teeth 12 can rotate stably.

[0071] Preferably, the mounting seat 19 and the fixing plate 15 are respectively provided with first waist-shaped holes parallel to each other, and the fixing plate 16 is further provided with a second waist-shaped hole, which is in an arc shape.

The two belts 22 are arranged in close proximity, and the two belts 22 are arranged on the first frame 7 and rotate in opposite directions to clamp the carrot leaves and drive the carrots to be transported obliquely upward along the first frame 7. A guide rubber wheel 23 is arranged below the first frame 7. The guide rubber wheel 23 is circular and the edge is serrated.

The guide rubber wheel 23 is arranged at the bottom of the driven pulley, and the guide rubber wheel 23 is made of rubber material. The teeth on its edge can gather, converge and guide the carrot leaves entering between the two belts 22, so as to avoid the loose carrot leaves causing the belt 22 to be unable to clamp effectively.

[0107] The two limiting chains 41 in the clamping and aligning device 4 are arranged side by side and at intervals to form a limiting channel. The width of the limiting channel is smaller than the width of the carrot, so as to limit the carrot lifted to a certain height by the leaf clamping and conveying device 1.

After contacting the limiting chain 41, the fruit can continue to be driven and perform a synchronous planar movement with the leaves clamped by the leaf clamping conveying device 1 on the top, thereby avoiding the fruit being stuck due to the fruit being limited by the leaves being driven to move only, ensuring the carrot alignment effect, avoiding damage to the fruit, and reducing the bad fruit rate; a Z-shaped connecting plate 44 is set, and the end of the limiting chain 41 extends out of the second frame 8, and is tilted with the end of the second frame 8, with an angle, which is adapted to the leaf clamping conveying device 1 tiltedly set on the harvester, avoiding interference between the second frame 8 and the leaf clamping conveying device 1, and facilitating the carrots to enter between the two second frames 8 for limit alignment; by reinforcing ribs 53 increases the strength of the connecting plate 44, avoids deformation of the Z-shaped connecting plate 44, and improves the service life of the connecting plate 44, thereby improving the service life of the entire device; the chain guide rail 54 is set to limit and guide the limit chain 41 through concave-convex matching, and at the same time can ensure the tension of the limit chain 41, so that two limit chains 41 with a certain distance can also be set closely, and the large distance at the end is convenient for carrots to enter between the limit chains 41, and the middle is close to limit the carrot fruit; preferably, a waist-shaped hole is set on the guide rail mounting plate, and the distance between the two chain guide rails 54 can be adjusted, thereby changing the width of the limit channel, limiting carrots of different sizes, and the tension of the limit chain 41.

The leaves between the leaf clamping conveying device 1 and the limiting chain 41 first enter between the two clamping belts in the lower clamping mechanism 42 and are clamped, driving the carrot to make horizontal linear motion. The top leaves are gradually pulled out of the leaf clamping conveying device, and then the top of the leaves enters between the two clamping belts in the upper clamping mechanism 43.

The lower clamping mechanism 42 clamps the bottom of the carrot leaves, and the upper clamping mechanism 43 clamps the blade part at the top of the leaves to prevent the carrot leaves from falling and affecting the cutting operation of the carrots by the blade 55. At the same time, the two sets of clamping mechanisms can clamp the carrots more stably, avoiding the carrots being shaken by the blade 55 during the cutting process, resulting in a skewed cutting position, thereby reducing the bad fruit rate; the two blades 55 in the blade group are single-sidedly sharpened, the inclination angles of the sharpened edges are equal, and the sharpened edges are on opposite sides, so that the two blades are sharpened. 55 are installed at the same height, and the sharpened blades are close to each other so that the two blades 55 partially overlap, the cutting effect is better, and the carrot fruit and leaves are completely separated, which avoids incomplete cutting and improves cutting efficiency; preferably, the longitudinal section of the connecting seat is an inverted T-shape, which increases the contact area between the connecting seat and the blade 55, ensures the stable installation of the blade 55, increases the stability of the blade 55, and extends the service life of the blade 55; the first installation shaft 47 is driven to rotate by the second transmission chain 48, driving the blade 55 to rotate for cutting, and at the same time, the transmission drives the first transmission chain 46 to rotate, thereby driving the limit chain 41 to run for limit alignment.
