Description

Technical Field

[0001] The invention relates to the technical field of feed processing equipment, and in particular to a raw material conveying equipment used for crushing and sorting high-yield pig feed. Background Art

[0002] With the continuous development of animal husbandry, the scale of pig farming is expanding, and the requirements for the output and quality of pig feed are getting higher and higher. In the process of pig feed production, the crushing and sorting of raw materials are crucial links. High-quality crushing and sorting operations can ensure the uniform distribution of nutrients in pig feed, improve the digestibility of feed, and meet the needs of pigs at different growth stages for feed particle size. At the same time, in large-scale production, the equipment footprint and processing efficiency also need to be considered to meet the requirements of high production.

[0003] At present, traditional pig feed raw material processing equipment often has problems such as single function, low efficiency or large footprint, which cannot meet the comprehensive needs of modern high-yield pig feed production. Pig feed raw material processing technology has many limitations in crushing and sorting. Some equipment cannot achieve effective mixing and compaction of raw materials when conveying raw materials, resulting in uneven subsequent crushing, affecting feed quality. In the crushing process, some equipment can only perform a single degree of crushing, lacking flexibility, and cannot perform adaptive crushing for raw materials of different specifications. Moreover, during the sorting process, most equipment can only achieve simple specification differentiation and cannot meet the requirements of multi-specification, high-precision sorting. In addition, traditional processing equipment is often a combination of multiple independent equipment, occupying a large area, and the overall crushing and sorting efficiency is low, which increases production costs and production cycles, and is not conducive to the production of large-scale high-yield pig feed.

The surfaces of the upper and lower transmission rods 13 are connected by two pulleys 12 and belts, and the back of the driving gear 10 on the left and the rear side of the transmission rod 13 on the top are also connected by two pulleys 12 and belts. Furthermore, a discharging rack 18 and a discharging rack 2 19 are fixedly provided on the right side of the sorting rack 17, the left side inside the discharging rack 2 19 is on the same horizontal line with the upper surface of the conveyor belt 15, and the top inside the discharging rack 18 is on the same horizontal line with the upper surface of the conveyor belt 2 16.

[0030] It should be noted that when the second crushing component is controlled to perform secondary crushing on the raw materials after preliminary sorting, the raw materials after preliminary sorting are fed into the interior of the sorting frame 20 through the discharging frame 18, and the crushing gap between the two crushing belts 21 is preset, and the output shaft of the driving motor 25 cooperates with the pulley 28 to drive the driving gear 26 on the right to rotate counterclockwise. Since the tooth surfaces of the two driving gears 26 are engaged and transmitted, the crushing belt 21 on the left will rotate clockwise synchronously. Therefore, the secondary crushing of the raw materials is completed by the two relatively rotating crushing belts 21, and the crushing gap between the two crushing belts 21 is flexibly adjustable, so that the crushing requirements of raw materials of different specifications can be met. By crushing the raw materials for the second time and then further sorting them, raw materials of various specifications can be obtained at one time, thereby improving the crushing and sorting efficiency of the raw materials.

[0031] Specifically, the second sorting component includes a scraper rack 22, a scraper rack 22 is rotatably arranged at the lower part of the sorting rack 20, and one end of the output shaft of the driving motor 25 is fixedly connected to the interior of the scraper rack 22, a plurality of sorting slots are arranged at the bottom of the sorting rack 20, a screening rack 23 is fixedly arranged above the interiors of the plurality of sorting slots, and the mesh diameters of the plurality of screening racks 23 are different, a material blocking rack 29 is slidably arranged at the lower part of the interiors of the plurality of sorting slots, a plurality of micro electric cylinders 30 are also fixedly arranged at the bottom of the sorting rack 20, and the driving ends of the plurality of micro electric cylinders 30 are respectively fixedly connected to one side of the plurality of material blocking racks 29, a plurality of blanking racks 27 are also fixedly arranged at the bottom of the sorting rack 20, and the tops of the plurality of blanking racks 27 are respectively connected to the interiors of the plurality of sorting slots, and the bottoms of the plurality of blanking racks 27 are respectively connected to the interiors of the plurality of pneumatic conveying pipes 11.

[0032] It should be noted that when the two crushing belts 21 are used to perform secondary crushing on the raw materials after preliminary sorting, the output shaft of the second driving motor 25 synchronously drives the scraper frame 22 to rotate inside the second sorting frame 20, and the scrapers arranged on the outer peripheral surface of the scraper frame 22 are used to turn the secondary crushed raw materials inside the second sorting frame 20, and the screening frame 23 with the smallest mesh diameter is first controlled to perform secondary sorting on the secondary crushed raw materials, and the micro electric cylinder 30 is used to control the blocking frame 29 at the bottom of the screening frame 23 with the smallest mesh diameter.

Since the tooth surfaces of the two driving gears 26 are meshed and driven, the left crushing belt 21 will rotate clockwise synchronously, so the secondary crushing of the raw materials is completed by the two relatively rotating crushing belts 21; Step 5. When the two crushing belts 21 are used to perform secondary crushing on the raw materials after preliminary sorting, the output shaft of the second driving motor 25 synchronously drives the scraper frame 22 to rotate inside the second sorting frame 20, and the scrapers arranged on the outer peripheral surface of the scraper frame 22 are used to turn the secondary crushed raw materials inside the second sorting frame 20.
