DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, describe in detail the specific embodiments, structures, features, and their effects according to the present utility model.

[0024] Embodiment: Please refer to Figures 1-3 , an odor-proof dry sludge transfer carriage. The carriage body 2 is located on the vehicle body 1. A lifting hydraulic cylinder 27 is provided in the middle of the bottom of the carriage body 2, and a ground-supporting hydraulic cylinder 28 is provided at the tail of the carriage body 2. A carriage door 25 is rotatably connected to the upper side of the tail end of the carriage body 2. Switching hydraulic cylinders 26 are respectively provided on both sides of the tail end of the carriage body 2, and the piston rod of the switching hydraulic cylinder 26 is connected to the carriage door 25. The setting manners of the lifting hydraulic cylinder 27, the ground-supporting hydraulic cylinder 28, and the switching hydraulic cylinder 26 belong to the prior art and will not be elaborated here. The carriage body 2 can be lifted from the vehicle body 1 by the lifting hydraulic cylinder 27 for discharging materials. The ground-supporting hydraulic cylinder 28 is used to provide a supporting force for the carriage body 2 and the tail of the vehicle body 1 during lifting and discharging to prevent the vehicle from tilting backward. The switching hydraulic cylinder 26 is used to automatically open and close the carriage door 25, and compared with manually closing the carriage door 25, the switching hydraulic cylinder 26 can make the carriage door 25 closer.

[0025] A stepped groove 201 is formed around the carriage opening at the tail end of the carriage body 2. The carriage door 25 is in clearance fit with the stepped groove 201, and the stepped groove 201 makes it more difficult for gas to overflow. Sealing rubber strips are provided at each connection inside the carriage body 2 and at the gap between the carriage door 25 and the stepped groove 201 to achieve a sealed state inside the carriage body 2 and prevent odor from overflowing from the connection gaps. The setting of the sealing rubber strips can adopt the prior art.

[0026] At the top of the carriage body 2, there are a feeding port 23, an air extraction port 24 and a water inlet 22. There are two feeding ports 23 for feeding. Compared with feeding through the carriage door 25, it is more labor-saving, there is no need to frequently open and close the carriage door 25, and it is convenient to fill more materials. The two feeding ports 23 speed up the feeding speed. A sealing cover is installed at the end of the feeding port 23 to seal the feeding port 23. The sealing cover can be made of rubber material with a sealing function, etc. The air extraction port 24 is used to extract air from the inside of the carriage body 2 to form a slight negative pressure after feeding is completed and sealed, so as to prevent the odor from overflowing during transportation. A valve I is provided at the air extraction port 24. After the air extraction is completed, the valve I is closed to maintain the slight negative pressure state inside the carriage body 2. An aqueous pipe 221 is installed at the inner top of the carriage body 2 for cleaning the inside of the carriage body 2 after discharging. The aqueous pipe 221 is provided with water spray nozzles, and the water spray nozzles preferably face the inner wall surface of the nearby carriage body 2. The water inlet 22 is connected to the aqueous pipe 221. When cleaning is required, an external water source enters the aqueous pipe 221 from the water inlet 22. A valve II is provided at the water inlet 22, and the valve II is closed when not in use. The structure of the aqueous pipe 221 can be in an n shape or in a structure with a horizontal bar added in the middle of the n shape. The latter is preferred. The n shape enables each inner wall surface of the carriage body 2 to be cleaned and flushed. The structure with a horizontal bar added in the middle of the n shape increases the flushing force on the inner bottom wall of the carriage body 2 on the basis that each inner wall surface of the carriage body 2 can be cleaned and flushed, and it is convenient to flush the sludge flowing from the wall surface to the bottom wall out of the carriage body 2.

[0027] On one side of the head of the carriage body 2, a ladder 21 is fixedly connected. The self - contained ladder 21 makes it convenient for workers to climb to the top of the carriage body 2 for operations such as feeding, flushing, and air extraction. The top of the ladder 21 is fixedly connected with a handrail 211, which improves the safety and convenience of use.

[0028] The working principle of this embodiment: A deodorizing dried sludge transfer carriage provided in this embodiment. When loading, workers climb to the top of the carriage body 2 through the ladder 21 and feed through the feeding port 23 at the top of the carriage body 2. After feeding is completed, cover the sealing cover, check the airtight state of the carriage body 2, and then extract air from the inside of the carriage body 2 through the air extraction port 24 to form a slight negative pressure to prevent the odor from overflowing during transportation. When discharging, open the carriage door 25 by operating the hydraulic cylinder 26, and lift the carriage body 2 from the vehicle body 1 by the lifting hydraulic cylinder 27 for dumping. The supporting hydraulic cylinder 28 provides a supporting force for the carriage body 2 and the tail of the vehicle body 1 during the lifting and dumping process to prevent the vehicle from tilting backward. After discharging is completed, an external water source enters the aqueous pipe 221 from the water inlet 22 to clean and flush the inside of the carriage body 2. The deodorizing dried sludge transfer carriage realizes airtight anti - odor and prevents odor from overflowing.
