specific Embodiment approach

[0023] Referring to the accompanying drawings, the specific implementation is as follows:

[0024] like figure 1 As shown, a self-adaptive adjustable threshing machine based on the detection of threshing force includes a frame 1 on which an axial flow threshing device is installed. The axial flow threshing device includes a cylinder 2 arranged horizontally. The body 2 is provided with a bar-type threshing drum 3, and a grid-shaped concave plate 4 is arranged under the bar-type threshing drum 3. The two ends of the cylinder body 2 are respectively provided with a feed inlet 5 and a miscellaneous outlet 6. 1 side is also equipped with a motor 7, the motor 7 drives the threshing drum 3 to rotate through the transmission belt 12, and the rotation of the threshing drum 3 cooperates with the grid-shaped concave plate 4 to separate the grain from the straw and is screened by the grid-shaped concave plate 4 The straw after threshing is discharged from the cylinder body 2 from the mis...

Abstract

A threshing machine with self-adaptive adjustment of concave plate gap based on threshing force detection, including a frame, an axial flow threshing device is installed on the frame, and a grid-shaped concave plate is arranged under the bar-shaped threshing drum of the axial flow threshing device The frame is equipped with a telescopic mechanism that can drive the grid concave plate to move in the vertical direction, and the frame is also equipped with a displacement sensor that can detect the height of the grid concave plate; the grid concave plate is close to the side of the threshing drum There are multiple sets of stress sensors installed on the screen surface, and the tangential force on the grid concave plate is detected by the stress sensors and transmitted to the controller in real time. The weight distribution ratios corresponding to all the stress sensors are preset in the controller , the controller calculates the effective value of the threshing force, compares the effective value of the threshing force with the optimal threshold value of the threshing force stored in the controller, and controls the telescopic mechanism to drive the grid concave plate to move to the optimum threshold of the threshing force according to the comparison result. The height corresponding to the optimal threshold can realize the automatic real-time adjustment of the concave plate gap.

Description

technical field [0001] The invention relates to the field of threshing devices, in particular to a threshing machine with self-adaptive adjustment of concave plate gap based on threshing force detection. Background technique [0002] As a key machine in the combined harvesting process, the thresher's working status directly determines the performance of the whole machine. At present, most of the threshing devices on the market are mechanically fixed, and it is difficult to realize the self-adaptive adjustment of its internal structure and working parameters. Under the conditions of different harvesting objects or different growth states of agricultural materials, poor threshing effect and drum Problems such as blockage seriously affect harvesting efficiency and delay farming time. The main reason is that the combination of threshing elements and concave screens produces different threshing mechanisms. The threshing mechanism between threshing materials is mainly manifested ...
