Description

Technical Field

[0001] This utility model relates to the technical field of corn harvester crushing boxes, and in particular to a corn harvester crushing box. Background Technology

[0002] In the corn harvesting process, the handling of materials such as corn stalks is crucial. Traditional corn harvesters offer limited post-harvest processing methods, failing to efficiently crush corn stalks and other materials. This results in poor stalk decomposition during return to the field, impacting soil structure and subsequent cultivation. To improve the overall efficiency of corn harvesting operations and optimize the handling of stalks and other materials, the development of a high-efficiency corn harvester crushing box is essential. This corn harvester crushing box, through a series of carefully designed components, effectively solves the aforementioned problems and improves the overall efficiency of corn harvesting. Based on this, a corn harvester crushing box is proposed to address the issues raised in the background technology. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a corn harvester crushing box, which solves the problem that traditional corn harvesters have relatively simple post-harvest material processing methods and cannot efficiently crush corn stalks and other materials. This results in the stalks being difficult to decompose when returned to the field, affecting soil structure and subsequent cultivation. In order to improve the overall efficiency of corn harvesting operations and optimize the processing effect of materials such as stalks, the development of an efficient corn harvester crushing box has become an inevitable requirement.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a corn harvester crushing box, including a crushing box, the crushing box being provided with a connecting mechanism, the connecting mechanism including a connecting component disposed on the outer wall of the crushing box, receiving components disposed at the front and rear ends of the crushing box, and a crushing component disposed in the inner cavity of the crushing box;

[0005] The crushing assembly includes a rotating shaft rotatably connected to the inner wall of the crushing box. Dividers are fixedly connected at equal intervals to the outer wall of the rotating shaft. Connecting rods are fixedly connected between adjacent dividing plates. A chain is sleeved on the outer wall of the connecting rod, and crushing blocks are fixedly connected to the outer end of the chain.

[0006] A further improvement is that the connecting assembly includes a connecting port disposed at the top of the crushing box, a guide plate is fixedly connected to the middle section of the inner wall of the connecting port, side plates are fixedly connected to the outer walls on both sides of the crushing box, a locking plate is fixedly connected to the outer wall of the crushing box, a locking rod is hinged to the inner wall of the locking plate, an installation plate is hinged to the outer wall of the crushing box, and a cabinet plate is fixedly connected to the inner side of the installation plate.

[0007] A further improvement is that the receiving component includes a base frame fixedly installed on both sides of the bottom of the crushing box, a mounting frame one fixedly installed on one end of the back of the crushing box, a bearing frame one fixedly installed on the top of the mounting frame one, a mounting frame two fixedly installed on one end of the front of the crushing box, a bearing frame two fixedly installed on the top of the mounting frame two, and a transmission wheel fixedly connected to the outer wall of the rotating shaft.

[0008] A further improvement is that the outer wall of the rotating shaft is fixedly connected to the inner wall of the bearing bracket; when the transmission wheel rotates under power drive, it drives the rotating shaft to rotate together; the partition plates fixedly connected at equal intervals to the outer wall of the rotating shaft rotate with the rotating shaft, and the connecting rods fixedly connected between adjacent partition plates also rotate accordingly.

[0009] A further improvement is that the guide plate is symmetrically and inclinedly arranged on the inner wall of the connecting port; the guide plate is fixed in the middle section of the inner wall of the connecting port and is symmetrically and inclinedly arranged; its function is to guide the corn stalks and other materials conveyed from other parts of the harvester so that they can be evenly dispersed into the crushing box and avoid the material from accumulating at the inlet.

[0010] A further improvement is that the first bearing bracket is symmetrically arranged on the top of the first mounting frame, and the second bearing bracket is symmetrically arranged on the top of the second mounting frame; the outer wall of the rotating shaft is fixedly connected to the inner wall of the first bearing bracket, and the rotating shaft can rotate stably under the support of the first and second bearing brackets; the transmission wheel is fixedly connected to the outer wall of the rotating shaft, and is connected to the power output device of the corn harvester to receive power and drive the rotating shaft to rotate.

[0011] A further improvement is that the crushing blocks are equidistantly arranged and symmetrically arranged on the outer side of the symmetrically arranged rotating shaft; the partition plates fixedly connected at equal intervals to the outer wall of the rotating shaft rotate with the rotating shaft, and the connecting rods fixedly connected between adjacent partition plates also rotate accordingly; due to the driving of the connecting rod, the chain sleeved on the outer wall of the connecting rod rotates at high speed, and the crushing blocks fixedly connected to the outer end of the chain rotate at high speed during the rotation.

[0012] By employing the above technical solution, this utility model provides a corn harvester crushing box, which has at least the following beneficial effects:

[0013] 1. The unique crushing component design of the crushing box of this corn harvester enables efficient crushing operations. When the shaft rotates, it drives the partition plate, connecting rod, and chain sleeved on the connecting rod to move together, and the crushing blocks fixed at the outer end of the chain rotate at high speed. Since the crushing blocks are equidistantly and symmetrically arranged on the outside of the shaft, they can crush corn stalks and other materials entering the crushing box in an all-round and high-density manner. Compared with traditional processing methods, it greatly shortens the material crushing time, can process more material per unit time, significantly improves the overall efficiency of material processing during corn harvesting, and speeds up the harvesting operation.

[0014] 2. Traditional corn harvesters are ineffective at crushing straw, making it difficult for straw to decompose after being returned to the field. This crushing box, however, efficiently breaks down corn stalks and other materials into smaller fragments. These finer fragments are more easily decomposed by microorganisms in the soil, accelerating the release of nutrients and improving soil structure and fertility. The finer fragments are also more evenly distributed in the soil, unlike large clumps that hinder subsequent cultivation, providing more favorable soil conditions for crop growth. In the long run, this contributes to increased crop yield and quality, achieving sustainable agricultural development. Attached Figure Description
