Description

Technical Field

[0001] The invention relates to the technical field of vehicles, in particular to a vehicle feed port cover and a control method thereof. Background Art

[0002] At present, the domestic livestock and poultry industry has developed rapidly and has formed a large-scale, industrialized and automated industry. In this large-scale industry, biosafety is increasingly valued. If the feed is contaminated, the livestock and poultry of the farmers are very likely to die on a large scale, resulting in losses for the farmers. Therefore, feed mills and farms all use automation technology. The feed in the feed mill is automatically loaded into bulk feed transport vehicles after high-temperature drying and disinfection. The feed trucks transport the feed to the storage tower outside the farms through automatic unloading. The farms use automatic feeding technology to deliver the feed to the mouths of livestock and poultry. However, before loading the feed, the feed port cover of the feed truck is generally opened and closed manually, which invisibly increases the biosafety risk. In order to facilitate loading and achieve a higher filling coefficient in the tank, the feed port is designed to be larger and larger, and there is almost no platform on the top of the tank. There is also a great personal safety hazard when workers walk on the top of the tank to manually open and close the feed port cover. Summary of the invention

[0003] One of the purposes of the present invention is to provide a vehicle feed port cover, which can solve the problem that the existing vehicle feed port cover needs to be opened and closed manually, which increases biosafety risks and poses a hidden danger to personal safety.

[0004] In order to solve the above problems, the technical solution adopted by the present invention is: this vehicle feed port cover includes a cover body installed on the tank mouth of a transport tank, and the tank mouth of the transport tank is divided into an even number of feed ports by a partition along the width direction, and a cylinder is arranged on the partition between every two adjacent feed ports; the cover body is composed of sub-cover bodies corresponding to the number of feed ports, and the two sub-cover bodies arranged on both sides of the cylinder are connected to form a sub-cover body pair by a connecting strip, and the connecting strip spans the cylinder; the two sides of the sub-cover body are slidably connected with the two sides of the adjacent partition, and the telescopic rod of the cylinder is connected to a connecting seat located on the outside when the sub-cover body pair moves outward.

[0005] In the technical solution of the above-mentioned vehicle feed port cover, a more specific technical solution can also be: guide rails are arranged on both sides of each of the partitions, and guide rail telescopic rods corresponding to the guide rails are arranged on both sides of each of the sub-cover bodies, and the telescopic rods are connected and fixed to the sub-cover bodies through the inner wing plate part; the guide rail is a cylinder with an opening, and the telescopic rod is inserted into the guide rail, and the outer diameter of the end of the telescopic rod in the guide rail is larger than the inner diameter of the outlet of the guide rail.

[0006] In some possible implementation schemes, guide rails are provided on both sides of each of the sub-cover bodies, and guide rail telescopic rods corresponding to the guide rails are provided on both sides of each of the partitions, and the telescopic rods are connected and fixed to the partitions through the inner wing plate parts; the guide rail is a cylinder with an opening, and the telescopic rod is inserted into the guide rail, and the outer diameter of the end of the telescopic rod in the guide rail is larger than the inner diameter of the outlet of the guide rail.

[0007] In some possible implementation schemes, a plurality of rows of ribs are evenly arranged on the surface of the sub-cover body, and both ends of the connecting strip are welded and fixed to the ribs.

[0008] In some possible implementation schemes, the length L of the guide rail is less than or equal to the width of the tank body and greater than or equal to the width of the sub-cover body.

[0009] In some possible implementation schemes, the length of the guide rail telescopic rod is less than or equal to the width of the tank body and greater than or equal to the width of the sub-cover body.

[0010] Another object of the present invention is to provide a control method for opening the vehicle feed port cover of the transport tank cover body by the driver in the cab.

[0011] In order to solve the above problems, the technical solution adopted by the present invention is: It includes an air-controlled valve, the inlet of which is connected in series with an oil-water separator and a stop valve through a pipeline and then connected to an air cylinder, and the outlet of the air-controlled valve is respectively connected to the front end and the rear end of the cylinder through two pipelines, wherein the stop valve, the oil-water separator and the air-controlled valve are installed in the cab. When the pressure of the air cylinder reaches 6-12MPa, the stop valve is opened, and the air pressure flows out through the inlet and outlet of the air-controlled valve to reach the front end of the cylinder, the telescopic rod of the cylinder is in a retracted state, and the sub-cover body is in a closed state; conversely, when the air-controlled valve is pulled, the air pressure flows out through the inlet and outlet of the air-controlled valve to reach the rear end of the cylinder, the telescopic rod of the cylinder is in an extended state, and the sub-cover body is in an open state.

[0012] In some possible implementation schemes, the air-controlled valve is a two-position five-way air-controlled valve.

[0013] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art: 1. The cylinder pushes or retracts the telescopic rod of the cylinder to drive the opening or closing of the sub-cover body, avoiding the biosafety risk of personnel contacting the feed during the loading process, and there is no need to manually climb onto the tank top, thereby reducing the workload and personal safety of workers. At the same time, the opening and closing speed of the feed inlet cover is increased, improving work efficiency.

[0014] 2. Since the cylinder is arranged between the sub-cover body pair, the sub-cover body pair is closed and opened, the sub-cover body pair is evenly stressed and operates flexibly.

[0015] 3. The sliding connection between the guide rail and the guide rail telescopic rod makes the sub-cover body more stable and smooth when sliding, reducing the error caused by shaking.

[0016] 4. Since the stop valve, oil-water separator and two-position five-way air-controlled valve of the control system are installed in the cab, the driver does not need to get off the vehicle when unloading. He can operate in the cab to open the cover, prohibiting the driver from getting off the vehicle to reduce the pollution risk of outsiders, reduce the workload and personal safety of workers.
