Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a height adjustment device for the upper and lower threshing bins of corn threshers, through which the height of the upper and lower threshing bins can be adjusted at the same time to meet the needs of the corncobs in the upper and lower threshing bins. Fast threshing can be carried out in both, and there will be no situation where the corn cob is stuck or broken due to the large diameter of the cob, and there will be no situation that the corn cob cannot be removed because of the small diameter of the cob.

Embodiment 1

[0022] Such as figure 1 As shown, the height adjustment device for the upper and lower threshing bins of the corn thresher includes a shift gear 1, an adjustment handle 2, and an adjustment arm. The adjustment handle 2 is snapped into the gear slot of the shift gear 1. The adjustment arm is connected; the adjustment arm is divided into the adjustment rear arm 3 and the adjustment forearm 4. The section closer to the adjustment handle 2 is the adjustment rear arm 3, and the farther section from the adjustment handle 2 is the adjustment forearm 4. The adjustment rear arm 3 and the adjustment forearm 4 There is a rotating support point between them, and the adjusting rear arm 3 and the adjusting forearm 4 can rotate around the rotating supporting point. The adjusting rear arm 3 is connected with the upper threshing bin adjusting arm 5, and the upper threshing bin adjusting arm 5 is connected with the bin shell on the corn thresher. 6 connection; the adjustment forearm 4 is connec...

Embodiment 2

[0027] According to the height adjustment device for the upper and lower threshing bins of the corn thresher described in Embodiment 1, a shifting reset device 9 can be arranged between the adjusting handle 2 and the adjusting rear arm 3, and the shifting reset device 9 includes a shifting box, The gear adjustment rotating shaft and the reset tension spring, the adjusting rear arm 3 is connected with the gear shifting box, the gear adjusting rotating shaft is connected with the adjustment handle 2, one end of the reset tension spring is connected with the gear adjustment clip, and the other end of the reset tension spring is connected with the adjustment handle 2 connect. The adjustment handle 2 is pulled back by the return spring, so that the adjustment handle 2 can be quickly clamped in the gear slot, and will not loosen and disengage from the gear teeth, which improves the adjustment stability of the entire adjustment device.

[0028] After the device is installed on the co...

Embodiment 3

[0030] Such as figure 2 As shown, according to the height adjustment device for the upper and lower threshing bins of the corn thresher described in Example 1, the rotating support point can be realized by using the rotating support hole 11 in cooperation with the screw rod, and the specific structure is as follows:

[0031]A positioning piece 10 is arranged between the adjusting front arm 4 and the adjusting rear arm 3, and a rotating support hole 11 is arranged on the positioning piece 10, and the positioning piece 10 is fixed on the corn thresher by a screw. A supporting piece is arranged on the corn thresher, and the positioning piece 10 is located between the thresher and the supporting piece, and the screw passes through the supporting piece, and the positioning piece 10 is fixed on the corn thresher. The screw rod cooperates with the rotation support hole 11 as a rotation support point. The horizontal displacement of the positioning piece 10 is limited by the limited ...

Abstract

The invention discloses an upper threshing warehouse and lower threshing warehouse height adjusting device used for a corn thresher. The upper threshing warehouse and lower threshing warehouse height adjusting device used for the corn thresher comprises gear shifting teeth, an adjusting handle and adjusting arms, wherein the adjusting handle is clamped into a gear tooth groove of the gear shifting teeth; the adjusting handle and the adjusting arms are connected; the rear adjusting arm and the front adjusting arm of the adjusting arms rotate with a rotating supporting point as the rotating center; the rear adjusting arm drives an upper threshing warehouse adjusting arm connected with the rear adjusting arm to move; the upper threshing warehouse adjusting arm drives a warehouse shell to move; the front adjusting arm is connected to the lower portion of a bottom pressing board at the lower end of a threshing cylinder in a sleeved mode; the front adjusting arm pulls the bottom pressing board to move; in this way, the height of an upper threshing warehouse and the height of a lower threshing warehouse can be adjusted at the same time, corn can be rapidly threshed not only in the upper threshing warehouse but also in the lower threshing warehouse, the corn is prevented from being clamped or being broken when the diameter of the corn is large, and the corn can be completely threshed even when the diameter of the corn is small.

Description

technical field [0001] The invention relates to the field of corn threshers, in particular to a height adjustment device for upper and lower threshing chambers of corn threshers. Background technique [0002] In the field of traditional small corn threshers, there are two types of corn threshers, one is a thresher that feeds corn cobs horizontally, and the other is a thresher that feeds corn cobs vertically. [0003] Because the vertical feeding corn thresher is not easy to break the core, the threshing effect is better than the horizontal feeding corn thresher, so the horizontal feeding corn thresher is almost eliminated. For the vertical feed corn thresher, there is a further design, because the diameter of the corn cob is different, so when entering the threshing bin, the height of the threshing bin needs to be adjusted according to the diameter of the corn cob, so some threshing occurs. Bin height adjustment device. [0004] For example, the publication number is CN101...
