Description

Technical Field

[0001] The present invention relates to the technical field of corn harvesters, and in particular to an intelligent agricultural machinery corn harvester. Background Art

[0002] Corn harvesters are important tools for modern agricultural mechanization. One of their core components is the ear picking board, which is responsible for picking corn ears from the plants during the harvesting process and is a key link in ensuring the quality of the harvest.

[0003] However, in the current corn harvester design, there are the following problems:

[0004] 1. The ear picking plates cannot detect the spacing by themselves, nor can they be adjusted automatically. This limitation means that in actual operation, the operator needs to manually adjust the spacing of the ear picking plates to adapt to corn plants with different growth conditions;

[0005] The main reasons for this problem can be attributed to the following aspects:

[0006] 1. The design of existing corn harvesters often focuses on the optimization of the overall structure and power system, while ignoring the intelligent upgrade of the detail function of adjusting the spacing between ear picking plates;

[0007] 2. Due to the limitations of the development level of sensor technology and intelligent control algorithms, it is difficult to integrate a high-precision, high-reliability automatic detection and adjustment system on the ear picking board.

[0008] To sum up, the corn harvesters currently on the market do not have the function of real-time monitoring of the spacing between ear picking plates, nor do they have the function of automatic adjustment. The manual adjustment method is not only inefficient and increases labor intensity, but also difficult to ensure the accuracy and consistency of the adjustment, which in turn affects the corn harvesting efficiency and quality. For this reason, we propose an intelligent agricultural machinery corn harvester. Summary of the invention

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Example 1: Please refer to Figure 1-Figure 11 , the present invention provides a technical solution:

[0045] An intelligent agricultural mechanical corn harvester includes a machine body 1 and a header 10. The machine body 1 and the header 10 are both common existing structures and will not be described in detail herein. The machine body 1 and the header 10 also include:

[0053] The monitoring control unit 3 includes two shift plates 31 slidably arranged on each group of two bottom plates 13, each bottom plate 13 is provided with a connecting piece 4 for adjusting the displacement of the ear picking plate 14, a monitoring component 5 is arranged between the two shift plates 31, and is used for real-time monitoring of the spacing between two adjacent ear picking plates 14, and an adjustment component 7 is arranged between the two bottom plates 13, and is used for automatically adjusting the spacing between the two ear picking plates 14 in cooperation with the monitoring component 5;

[0054] A plurality of straight slots 41 are provided on the bottom plate 13, and the connecting member 4 includes a plurality of screws 42 movably arranged in the straight slots 41, and both ends of the plurality of screws 42 are sleeved with fixed seats 43, and both ends of the screws 42 are provided with nuts, and a U-shaped seat 44 is provided on the upper fixed seat 43, and the ear picking plate 14 is provided on the lower fixed seat 43, and the ear picking plate 14 is respectively connected to the adjacent shifting plate 31, and the U-shaped seat 44 and the ear picking plate 14 are adjusted synchronously through the connecting member 4, which is conducive to ensuring the efficiency of corn harvesting;

[0055] The monitoring assembly 5 includes a mounting cavity 51 on any one of the shift plates 31, a piston rod 1 52 is arranged in the mounting cavity 51, the piston rod 1 52 is connected to the shift plate 31 away from the mounting cavity 51, a support plate 53 is arranged between the two bottom plates 13, a guide plate 54 is arranged on the support plate 53, and a connecting piece 6 is arranged on the support plate 53 for driving the adjustment assembly 7 to work through the displacement of the piston rod;

[0056] The connecting member 6 includes a fixed cavity 61 disposed on the support plate 53, piston rods 62 are movably disposed on both sides of the fixed cavity 61, and a connecting pipe 63 is disposed between the installation cavity 51 and the fixed cavity 61;

[0061] The monitoring control unit 3 monitors the distance between two adjacent ear-picking plates 14 in real time through the shifting plate 31, the monitoring component 5, the connecting piece 6 and the adjusting component 7, and adjusts it through the controller 71 and the electric push rod 82;

[0062] When the spacing changes, the two shift plates 31 shift, which can drive the piston rod 1 52 and the installation cavity 51 to produce relative displacement, thereby changing the gas in the installation cavity 51. The piston rod 1 52 in the monitoring component 5 senses and transmits a signal, and controls the gas to enter or discharge the fixed cavity 61 through the connecting tube 63, so that the piston rod 2 62 in the fixed cavity 61 moves, drives the conductive column 92 to slide on the resistance layer 91, changes the circuit resistance value, and then controls the extension or contraction of the electric push rod 82, drives the shift plate 31 to move, and realizes the automatic adjustment of the spacing of the ear picking plates 14;

[0063] When the spacing between the ear picking plates 14 is adjusted to a preset range, the monitoring component 5 stops sending the adjustment signal, the system maintains a stable state, and continues to perform corn harvesting operations efficiently and accurately.

[0064] Example 2: Please refer to Fig.12 , the present invention provides a technical solution:

[0065] Different from Example 1, a sealing cover 15 is provided on the positioning seat 72, and the piston rod 62 is movable through the sealing cover 15. The provision of the sealing cover 15 is conducive to ensuring the normal operation of the resistance layer 91 and the conductive column 92, avoiding circuit failures, and facilitating the normal use of the corn harvester.
