Novel side manhole

Abstract

The invention discloses a novel side manhole. The side manhole comprises a side manhole shell, a check block, a manhole cover, a supporting device, a locking device, locating plates, a handle and a sampling device. The side manhole is formed in the lower portion of one side of a milk tank vehicle tank. The same type of milk tank vehicles in domestic is not provided with the novel side manhole. Theside manhole is generally mounted on the top of the milk tank vehicle tank and is called as an upper manhole. Compared with the upper manhole, the side manhole has obvious advantages. After milk is loaded into the tank vehicle, the manhole cover cannot be opened. In this way, other substances cannot be mingled into the milk before the milk tank vehicle tank goes into a milk plant, and the safetyand hygiene of fresh milk are guaranteed. Compared with a manhole located in the top of the tank vehicle, unnecessary additional devices, such as a pedal, are omitted, and the unladen mass of the whole vehicle is effectively reduced. The milk sampling device is further arranged on the side manhole, so that a worker does not need to climb up the top of the tank to conduct sampling in the fresh milkplant. The climbing labor intensity of the worker and the falling risk of the worker are reduced. The situation that the upper manhole is opened and dust falls into the milk is avoided.

Description

technical field [0001] The invention relates to the technical field of milk tank trucks, in particular to a novel side manhole. Background technique [0002] The side manhole of the milk tanker is a very important part of the milk tanker. It is the passage for personnel to enter the milk tanker for cleaning, inspection, maintenance and repair. At present, the side manhole of the milk tanker in China is usually installed on the top of the milk tanker. It is called the upper manhole; it needs to be climbed, it is extremely inconvenient and dangerous to use; in addition, the structure and function of the side manhole of the current domestic milk tanker are single; when used on the top, dust is easy to enter the tank body of the milk tanker. Contents of the invention [0003] The purpose of the present invention is to provide a new type of side manhole to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present ...
