Description

Anti-disengaging frame for corn thresher Technical Field The utility model relates to the technical field of corn thresher frames, in particular to an anti-threshing frame for a corn thresher. Background The corn thresher is an agricultural machine for separating grains on corn ears from a mandrel through mechanical impact, kneading or axial-flow roller rotation, wherein a separation preventing frame is one of important parts of the corn thresher and can support and facilitate movement of the corn thresher; The existing corn thresher is directly connected with the anti-drop frame at the lower end in a bolt fixing mode, the rigid connection structure has obvious defects, in the running process of equipment, the machine is easy to generate displacement due to vibration due to lack of an effective positioning component and a vibration reduction component, and in particular, when high-strength threshing operation is performed and the corn thresher is positioned on uneven ground, the anti-drop frame for the corn thresher has the potential safety hazard of toppling, so that the design of the anti-drop frame for the corn thresher is needed to be considered for solving the problem. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides an anti-drop rack for a corn thresher, which is provided with a limiting mechanism aiming at the use problem, can conveniently realize stable limiting and vibration absorption of a corn thresher main body, avoid displacement or tilting of the corn thresher main body, and is further provided with two positioning assemblies, so that the stability of the equipment in a special working environment can be further improved, and the applicability is better. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The anti-drop rack for the corn thresher comprises a base, a supporting frame is arranged above the base, the supporting frame is fixedly connected with the base through a fixing frame, a corn thresher main body is arranged in the supporting frame, a limiting mechanism comprises two clamping plates arranged in the supporting frame, first rubber shock pads are fixedly arranged on the side walls of the two clamping plates, a first threaded rod is rotatably connected to the other side of the two clamping plates, the other end of the two first threaded rods penetrates through the supporting frame and is fixedly connected with a first rotating disc, the threaded ends of the two first threaded rods are in threaded connection with the supporting frame, and two positioning components are used for fixing the base. Preferably, the side walls of the two clamping plates are fixedly connected with guide rods, and the two guide rods penetrate through the support frame and are in sliding connection with the support frame. Preferably, the left side inner wall, the rear side inner wall and the inner bottom of the support frame are fixedly provided with second rubber shock pads. Preferably, the two first rubber shock-absorbing pads and the plurality of second rubber shock-absorbing pads are attached to the outer side of the corn thresher main body.
