Now, when a raised culm planted in a field by a traveling machine equipped with a threshing device is cut by a cutting blade (not shown), is lifted and conveyed by a stock carrier, and is transferred to a threshing feed chain 2. The grain culm is conveyed toward the handling plate 5 with the stock side clamped by the threshing feed chain 2. On the toothing 5a side of the handling plate 5, an ear carrier 7 composed of a wire conveyor is horizontally arranged. Since it is arranged in
In the conveying process, there is no delay in the tip of the spike and it is conveyed in synchronization with the root of the stock. In addition, the handling plate 5 is tilted vertically or backward with respect to the flow of the harvested culm so that the teeth 5a contact the tip of the culm from the tip. Since the culm is conveyed, the grain culm conveyed from the spike to the culm body in the direction of the culm is passed through the gripping plate 5 that vibrates up and down at a high speed while coming into contact with the gripping tooth 5a, and is threshed by the impact of the toothing 5a. Further, in the process of being pulled out and conveyed in the direction perpendicular to the vibration direction of the handling plate 5, the particles are shed by the impact of the handling teeth 5a. When being pulled out and transported, the tip side is transported along the curved surface 5b,
The flow of the culm is smooth, and the culm after threshing can be smoothly transported and discharged without disturbing the culm posture.

招く不具合がある。In the course of the above-described series of cutting and threshing operations, the amount of culms per unit time conveyed and supplied to the handling plate 5 by the threshing feed chain 2 varies depending on field conditions such as the density of planted culms. . A similar phenomenon occurs depending on the speed at which the vehicle speed (working speed) increases or decreases. For this reason, when the frequency of the handling plate 5 is constant, the frequency of contact with the tooth 5a decreases when the amount of culm increases, and the shedding rate decreases. When the amount of culm decreases, the tooth handling 5a decreases. In addition, there is a problem that the spike breaks due to excessive impact, which also lowers the shedding rate.

減に対し、５０Ｈｚ〜３０Ｈｚが好ましい。On the other hand, the frequency of the handling plate 5 is determined by the vehicle speed (working speed).
Can be varied according to That is, the vehicle speed (working speed) is detected by the rotation speed detector, a frequency corresponding thereto is calculated by the microcomputer 19, and based on the result, an AC wave of the corresponding frequency is generated from the inverter 20, and the vibration drive unit 6 By driving at a frequency, the handling plate 5 can be vertically reciprocated. Therefore, a suitable frequency can be set for each culm amount or for each vehicle speed, and it is possible to improve the shedding rate by minimizing shedding. According to the experiment, the variable range of the frequency is preferably 50 Hz to 30 Hz with respect to the increase and decrease of the culm amount.

を行うことができる。In short, in the present invention, the handling plate, in which the teeth are planted in a sword mountain shape, is reciprocated up and down, and the spike side of the cutting grain culm is transported and supplied to the handling plate by a threshing feed chain for threshing. The threshing device is configured to be able to change the frequency of the handling plate to a frequency corresponding to the increase or decrease of the amount of culm conveyed and supplied to the handling plate or to increase or decrease the vehicle speed. When the amount of culm to be transported and supplied increases, or when the vehicle speed increases, the frequency of the handling plate is increased, and when the culm amount is reduced or the vehicle speed is reduced, the frequency is reduced, so that it is always A suitable frequency can be set for each culm amount or each vehicle speed. Therefore, the tip side of the grain culm conveyed and supplied to the handling plate by the threshing feed chain contacts the teeth of the handling plate that vibrates at a frequency corresponding to the amount of culm or a frequency corresponding to the vehicle speed and impacts. As a result, the shedding of the attached grains is as small as possible, and the shedding rate can be remarkably improved, so that efficient threshing work can be performed.
