An integrated drying and screening equipment for straw processing

technical field

The invention belongs to the technical field of processing equipment, and in particular relates to an integrated drying and screening equipment for straw processing.

Background technique

Straw refers to the general term for the stems, leaves, and ears of mature crops, and usually refers to the remaining parts of wheat, rice, corn, potatoes, oilseeds, cotton, sugar cane and other crops after harvest. Chinese farmers use straw It has a long history. At the beginning, due to the low level of agricultural production, the amount of straw was small, so a small amount of straw was used to feed livestock, and most of it was burned as fuel, which undoubtedly caused a waste of resources. However, with the vigorous development of agriculture, since the 1980s, China's grain output has been greatly increased, and the amount of straw has gradually increased. There will be a large amount of surplus straw in rural areas, and the utilization of straw is becoming more and more More and more, the effective use of resources has been achieved, and the waste of resources has been effectively avoided.

Straw is a valuable biological resource. In addition to being used as a burning material, straw can also be used as a raw material for fertilizer and feed. However, whether it is used as a raw material for fertilizer or feed, there are requirements for the particle size of straw. The existing Screening equipment for straw processing often only has the function of screening straw particles, but cannot process the screened large particles. It needs to use additional crushing devices for further crushing, which will undoubtedly increase the working process and reduce work efficiency. The straw itself may have a certain amount of moisture after harvesting, so it may become moldy after the straw is screened and piled up, which is likely to affect the quality of the straw, and the existing screening devices for straw processing often do not have the function of drying the straw , so we propose an integrated drying and screening equipment for straw processing to solve the above problems.

There is a port 15, and two screening mechanisms matching the positions of the two ports 15 are respectively installed on the upper and lower sides of the screening barrel 12. The circular wrapping frame 14 is provided with openings 16 symmetrically up and down on the side of the circumference, and the circumference of the circular wrapping frame 14 Two guide assemblies matching the positions of the two openings 16 are installed on the side, the guide assemblies include two material guide plates 17, and the two material guide plates 17 are installed obliquely on the circumferential sides of the circular wrapping frame 14 respectively, and the openings 16 are located on both sides. Between the two material guide plates 17, inlets 171 are provided on the upper and lower sides of the rear end of the screening bucket 12, a matching opening 172 is provided on the upper side of the rear end of the circular installation bucket 11, and a coarse crushing mechanism is installed on the rear end of the circular installation bucket 11. , the discharge end of the coarse crushing mechanism is connected to the matching port 172;

The front end of the screening bucket 12 is equipped with a power mechanism that matches the two fine crushing rollers 13. A first transmission mechanism is provided between the power mechanism and the two screening mechanisms. Box 18, the lower side of one side of the circumference of the circular installation bucket 11 is provided with a connection port 19 communicating with the inside of the storage box 18, the connection port 19 is fixedly equipped with a material receiving box 20, and the lower end of the material receiving box 20 is equipped with a discharge assembly.

After screening, the smaller particles are discharged into the storage box 18 through the connection port 19. At the same time, the staff can start the blast drying simultaneously. Mechanism, the blower drying mechanism generates hot air directly to the inside of the storage box 18 and acts on the straw particles through a number of vent holes 21 to dry the straw particles. The vent holes 21 can only allow air to enter for ventilation and will not cause straw Particles leak out, so that mold can be avoided in subsequent accumulation after drying;

After the screening mechanism screens out the small straw particles, the large straw particles will stay inside the lower fan-shaped area, and the staff can start the second transmission mechanism at regular intervals through the timing module of the controller 1, and the second transmission mechanism will electrically screen the bucket. 12 Rotate 180°, so that the larger particles can be located in the fan-shaped area on the upper side again, and they will fall due to gravity, so that they can be crushed and screened again until they are crushed to a qualified size position, which is completed At the same time of high-efficiency screening, it is convenient to complete the secondary treatment of large particle materials, and can be crushed until it is qualified. No additional operations are required during the process, which can effectively increase the work efficiency of the staff. Finally, the crushed particles will be concentrated in the receiving material. The drying process is carried out in the box 20, and after the drying is completed, it can be discharged and collected through the discharge assembly, which can effectively prevent moldy phenomenon during subsequent storage and ensure the quality of the straw.
