Optimized access hood

Abstract

The invention discloses an optimized access hood which comprises a cushion plate and a hood body. The hood body is mounted on the right side of the cushion plate, first springs are mounted on the upper and lower sides of the inner wall of the right side of the hood body, a first insertion plate is mounted on the top end of each of the springs, a plurality of slots are formed in the outer wall of the first insertion plate, two second insertion blocks are inserted into connecting blocks, and a second pull rod is mounted on the outer wall of each of second insertion blocks. According to optimizedaccess hood disclosed by the invention, a first insertion block escapes the slots by pulling a first pull rod, so that a screw moves upward or downward along a nut and the second insertion plates orthird insertion plates move upward or downward therelong to achieve a purpose of changing the size of the opening of the hood body. The ventilating heat efficiency can be regulated manually to be accelerated, and the connecting rods are inserted into the second insertion plates, so that when the two second insertion plates and the third insertion plates are closed, the optimized access hood is more stable, the inner heat of the hood body is uniform, the utilization efficiency is high, and convenience is brought to production and life.

Description

technical field [0001] The invention relates to the technical field of access covers, in particular to a novel optimized access cover. Background technique [0002] In people's production and life, the access cover has been widely used due to its simple structure and convenient use. In the prior art, the main functions of the access cover on agricultural machines are divided into two points. The first is to provide important components For protection, the second is placed at the material inlet and outlet to prevent the product from being scattered and wasted. However, most of the inlet and outlet covers cannot guarantee uniform heat, high utilization rate and slow ventilation, which brings inconvenience to production and life. Contents of the invention [0003] The purpose of the present invention is to provide a novel optimized access cover to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the presen...
