Description

Technical Field

[0001] The present application relates to the technical field of agricultural machinery, and in particular to an intelligently controlled suspended crusher corn harvesting header. Background Art

[0002] With the rapid development of modern agricultural technology, corn harvester design and technological innovation have become key to improving agricultural production efficiency and reducing costs. In particular, during the corn harvesting process, the header, as the part that comes into direct contact with the crop, has a significant impact on harvesting efficiency and quality. Therefore, developing an efficient and intelligent corn harvesting header is crucial for the advancement of modern agriculture.

[0003] In existing corn harvester technology, the header is typically mechanically driven, with rotating blades cutting the corn stalks. A straw chopper is installed at the bottom to shred the stalks. However, this approach presents several issues. First, the stalk chopper and header are integrated into one unit. To meet stubble cutting requirements, the operator cannot raise the header during harvesting, otherwise shredding will occur. This also results in excessive stubble height, which reduces user satisfaction. With existing structures, the header's low cutting height, the large amount of straw fed to the header, and the heavy load on the header affect harvesting efficiency. Utility Model Content

[0004] In order to make up for the above deficiencies, the present application provides an intelligently controlled suspended crusher corn harvesting header to solve the problems raised in the above background technology.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention to solve the technical problem is as follows:

[0006] An intelligent controlled suspended pulverizer corn harvesting header comprises a frame, a header assembly is mounted on the top of one end of the frame, and a pulverizer assembly is mounted on the bottom, the header assembly and the side walls of the pulverizer assembly are respectively engaged with a header transmission chain and a pulverizer transmission chain, two pulverizer control cylinders are respectively hinged at the ends of the header assembly and the pulverizer assembly, a two-way control valve is mounted on the top of the frame, and a cylinder oil inlet pipe and a cylinder oil return pipe are provided between the two pulverizer control cylinders and the two-way control valve.

[0007] Furthermore, a pulverizer blade is provided inside the pulverizer assembly.

[0008] Furthermore, two sets of cutting platform cylinder telescopic rods and cutting platform cylinder bodies are installed between the frame and the cutting platform assembly. The cutting platform cylinder telescopic rods are arranged inside the cutting platform cylinder body. The telescopic ends of the cutting platform cylinder telescopic rods are hinged to the bottom end of the cutting platform assembly, and the bottom end of the cutting platform cylinder body is hinged to the top end of the frame.

[0009] Furthermore, a header height adjustment rod and a locking nut are provided on the outer wall of the header oil cylinder body, and the header height adjustment rod is bolted to the header oil cylinder body through the locking nut.

[0010] Furthermore, a sequence control valve is provided on the side wall of the frame, and the sequence control valve is installed on the oil inlet pipe of the oil cylinder.

[0011] Furthermore, the frame is provided with a drive system inside, and the output end of the drive system is engaged with a header drive chain, and the other end of the header drive chain is engaged with the header assembly.

[0012] The utility model has the following beneficial effects:

[0013] The optimized header and pulverizer in this utility model are controlled by separate hydraulic cylinders, enabling the harvesting of corn ears at high header clearance, reducing header load and improving harvesting efficiency. This also meets the agronomic requirements of pulverizing straw at the desired stubble height. Specifically, the operator pushes the down button on the two-way control valve and simply observes the header's stubble height. The restricted stop of the header's hydraulic cylinder generates a high-pressure signal. A controller controls the sequence, providing a signal to the pulverizer hydraulic cylinder, causing the pulverizer assembly to descend to the stubble height.

[0014] This new front-mounted pulverizer consistently operates at the required height above the ground, completely pulverizing straw without any leakage. This effectively increases the harvesting height of the header, reducing straw feed requirements, alleviating the stalk-pulling load, and improving harvesting efficiency. This header can accommodate corn cultivation operations with widely varying scion heights. It also meets the operator's needs for cross-region harvesting, demonstrating its wide adaptability.

[0015] The cutting table assembly and the pulverizer assembly of the utility model are precisely adjusted through the pulverizer control cylinder and an intelligent control system. They can automatically adjust the working parameters according to different terrains and crop conditions to achieve efficient and accurate harvesting. The suspended design reduces the frictional resistance between the pulverizer blade and the ground, reducing power consumption, while ensuring the stability of the pulverizer on different terrains, avoiding excessive crop stubble height, which affects planting in the next season. The height and angle of the cutting table assembly can be flexibly adjusted by retracting the telescopic rod of the cutting table cylinder to adapt to corn plants of different heights and lodging angles, ensuring the thoroughness of the harvest. The setting of the cutting table height adjustment rod and the locking nut makes the adjustment of the cutting table height more precise and easy to fix, further improving the convenience of operation.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0022] Example

[0023] See also Figure 1 、 Figure 2 、 Figure 3 A corn harvesting header with an intelligently controlled suspended pulverizer includes a frame 1. Frame 1, constructed of high-strength steel, serves as the foundation for the entire harvesting header. This frame not only ensures structural stability and durability but also efficiently withstands and transmits the various loads generated by the header assembly 2 and pulverizer assembly 3 during operation, providing solid support for corn harvesting operations. Both the header assembly 2 and pulverizer assembly 3 utilize components from existing corn harvesting headers, and their specific structure and operating principles are based on existing technologies.

[0024] See also Figure 1 、 Figure 2 、 Figure 3, an intelligent controlled suspended crusher corn harvesting header, including a header assembly 2 installed on the top of one end of a frame 1 and a crusher assembly 3 installed on the bottom; the side walls of the header assembly 2 and the crusher assembly 3 are respectively engaged with a header transmission chain 4 and a crusher transmission chain 5; two crusher control cylinders 6 are hinged at both ends of the header assembly 2 and the crusher assembly 3; a two-way control valve 7 is installed on the top of the frame 1; a cylinder oil inlet pipe 8 and a cylinder oil return pipe 9 are provided between the two crusher control cylinders 6 and the two-way control valve 7; a crusher blade 10 is provided inside the crusher assembly 3; two sets of header cylinder telescopic rods 11 and a header cylinder body 12 are installed between the frame 1 and the header assembly 2; a header height adjustment rod 13 and a locking nut 14 are provided on the outer wall of the header cylinder body 12; a sequential control valve 15 is provided on the side wall of the frame 1; the frame 1 has its own drive system, and the output end of the drive system is engaged with a header active chain 16. In this embodiment, the driving system may adopt an electric motor.

[0025] The header assembly 2 is securely bolted to one end of the frame 1, enabling efficient corn stalk capture and precise collection of corn ears. This mounting method not only ensures the stability and reliability of the header assembly 2, but also provides sufficient support to cope with various challenges during the harvesting process.

[0026] The operation of the header assembly 2 relies on the precise transmission of the header drive chain 4. This design ensures precise and smooth cutting, enabling the header to accurately and quickly capture corn stalks while ensuring the integrity and cleanliness of the corn cobs. This design significantly improves the quality and efficiency of harvesting operations, reduces the contact time between corn cobs and the header, and prevents damage and loss of corn cobs.

[0027] Among them, the stem pulling plate of the stem pulling roller of the cutting table assembly 2 has been specially treated and optimized, and has excellent wear resistance and gripping performance. The stem pulling plate of the stem pulling roller can quickly and accurately grab the corn stalks, and can maintain an efficient stem pulling effect even when facing hard straw. In addition, the cutting table assembly 2 is also equipped with an advanced collection system that can quickly collect the separated corn cobs to avoid scattering and waste. The collection system adopts the collection system on the cutting table in the prior art, which is a mechanism equipped on the cutting table assembly in the prior art. Its specific structure and working principle are the prior art.

[0028] The pulverizer assembly 3 is mounted at the bottom of the frame 1. Its primary function is to finely pulverize materials such as corn stalks remaining after harvest. To achieve efficient pulverization, the pulverizer assembly 3 is equipped with sturdy and sharp pulverizer blades 10, which can quickly and thoroughly cut the material into fine particles.

[0029] The pulverizer assembly 3 is connected to the drive system via a pulverizer transmission chain 5. When the drive system is activated, the transmission chain 5 drives the pulverizer blades 10 to rotate at high speed. This design not only ensures the stability and reliability of the pulverizer blades 10, but also enhances the pulverization effect by increasing the rotational speed, making the pulverized material more uniform and fine.

[0030] The pulverizer control cylinders 6, a key component, are two in total, precisely articulated at either end of the header assembly 2 and pulverizer assembly 3. Their primary function is to flexibly adjust the height and angle of the header assembly 2 and pulverizer assembly 3 to suit varying working conditions and operational requirements. The pulverizer control cylinders 6 also boast strong load-bearing capacity and stability. Constructed from high-strength materials, they can withstand significant loads and impacts. Furthermore, their sealing properties are fully guaranteed, ensuring stable performance even in harsh operating environments.

[0031] When encountering corn stalks of varying heights or needing to adjust the harvesting angle, the operator can activate the shredder control cylinder 6 through the control system. As the cylinder retracts and retracts, the header assembly 2 and shredder assembly 3 adjust their height and angle accordingly, ensuring that the header's stalk-pulling rollers can accurately grasp the corn stalks and that the shredder blades 10 can effectively process the remaining material.

[0032] The two-way control valve 7 is mounted on top of the frame 1. Its core function is to precisely control the flow rates in the cylinder inlet pipe 8 and the cylinder return pipe 9, enabling precise adjustment of the telescopic movement of the two pulverizer control cylinders 6 and the header cylinder telescopic rod 11. This design not only ensures flexible adjustment of the height and angle of the header assembly 2 and pulverizer assembly 3 to suit different work requirements, but also greatly improves operational flexibility and efficiency. Through the precise operation of the two-way control valve 7, the operator can easily adjust the angle of the header assembly 2 and pulverizer assembly 3, ensuring more accurate and efficient harvesting operations.

[0033] Between the frame 1 and the header assembly 2, the header cylinder telescopic rod 11 and the header cylinder body 12 form a key adjustment mechanism for flexibly adjusting the height and angle of the header assembly 2. Specifically, the header cylinder telescopic rod 11 is located inside the header cylinder body 12, with its telescopic end hinged to the bottom end of the header assembly 2, while the bottom end of the cylinder body is hinged to the top end of the frame 1. This design allows the header cylinder telescopic rod 11 to freely extend and retract within the cylinder body 12, thereby achieving precise adjustment of the height and angle of the header assembly 2 to accommodate different harvesting conditions and crop heights. This adjustment mechanism not only improves the flexibility and adaptability of harvesting operations, but also ensures efficiency and safety.

[0034] Mounted on the outer wall of the header cylinder 12 is a header height adjustment rod 13 and a lock nut 14. This design allows the operator to fine-tune the height of the header assembly 2 by adjusting the rod 13 and securing it with the lock nut 14. This fine-tuning mechanism not only improves operational precision but also ensures optimal harvesting results under varying operating conditions. With simple operation, the operator can easily adjust the header height to accommodate crops of varying heights, improving harvesting efficiency.

[0035] A sequence control valve 15 is installed on the side wall of the frame 1, located at a key position on the oil cylinder inlet pipe 8. This design precisely controls the sequence and flow of oil entering the cylinders, ensuring coordinated movement and stable operation of the header assembly 2, pulverizer assembly 3, and other related components during operation. The introduction of the sequence control valve 15 not only improves the accuracy and controllability of the operational process but also effectively ensures the efficient operation and long-term stability of the entire harvesting header system.

[0036] The operating principle of this intelligently controlled suspended pulverizer corn harvesting header is as follows: When in use, drive the harvester into the cornfield and activate the drive system within the frame 1, causing the header drive chain 16 to begin operation. This chain, in conjunction with the header drive chain 4 and the pulverizer drive chain, drives the header assembly 2 to prepare for harvesting and the pulverizer assembly 3 to prepare for pulverizing the corn stalks. Depending on the height of the corn plants, operate the header height adjustment lever 13 and, using the locking nut 14, adjust the height of the header cylinder 12 relative to the header assembly 2 to the appropriate position, ensuring that the header can smoothly contact and capture the corn stalks. The header drive chain 4 causes the header assembly 2 to begin harvesting the corn stalks and transfers them to the pulverizer assembly 3. The pulverizer blades 10 within the pulverizer assembly 3 begin operation, pulverizing the stalks. The pulverizer control cylinder 6 adjusts the position and angle of the pulverizer assembly 3 as needed to achieve the optimal pulverizing effect. Through two-way control valve 7 and sequence control valve 15, the intelligent control system monitors the operating status of the harvester and pulverizer in real time, automatically adjusting their operating parameters based on crop conditions to ensure smooth harvesting and pulverizing. After completing harvesting an area, the drive system and operating control system are disconnected, and the harvester moves to the next work area to continue operations.

[0037] It should be noted that the specific models and specifications of the crusher control cylinder 6, the two-way control valve 7, the cylinder oil inlet pipe 8, the cylinder oil return pipe 9, and the sequence control valve 15 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present application is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
