Description

Technical Field

[0001] This utility model belongs to the field of wheat processing technology, and specifically relates to a foreign matter screening device for winter rye. Background Technology

[0002] Winter rye is a highly adaptable winter forage crop belonging to the genus *Lycium* of the Poaceae family. It is drought- and cold-resistant, undemanding in terms of soil, and can grow in various environments, including poor and saline soils. Winter rye grows rapidly and greens up early, typically harvested from late May to early June, effectively alleviating the shortage of green fodder in early winter and early spring. Its well-developed root system provides significant windbreak and sand-fixing effects, while also improving land utilization and fertility, offering a scientific and efficient forage planting model for large-scale livestock farming. During processing, winter rye grains often require sieving to remove large stones.

[0003] Chinese Patent No. CN221361150U discloses a primary screening device for foreign matter in rye, comprising a box body, a door installed on the outer surface of the front side of the box body near the bottom, a feed pipe fixedly installed on the top of the box body, a vertical plate fixedly installed between the upper and lower inner walls near the middle of the box body, a screening plate snapped between the right wall of the box body and the right side of the vertical plate near the middle, an inclined plate fixedly installed between the right wall of the box body and the right side of the vertical plate near the bottom, a horizontal plate fixedly installed on the left wall of the box body, an auxiliary screening structure provided on the horizontal plate, a compaction component fixedly installed at the bottom of the horizontal plate, and a holding plate fixedly installed on the bottom wall of the box body.

[0004] While traditional winter rye foreign matter screening devices can basically meet the requirements for initial screening of mixed stones, there are still some shortcomings in actual use. For example, when feeding material into the screening plate inside the box through the feed pipe on the box, the feed amount cannot be effectively controlled, which can easily cause excessive feeding at one time, resulting in particle compression and affecting screening efficiency. Secondly, although continuously hitting the screening plate with a striking block can improve the screening effect through vibration, long-term use can easily damage the screening plate.

The collection drawer is inserted into the inner side of the positioning groove, and an observation window is provided on the inner side of the front of the box door.

[0015] In summary, the present invention has the following main advantages:

[0016] First, the agitator is driven by the output of the stirring motor to stir in the storage box, and the heating plate in the storage box can dehumidify the winter rye. During the initial screening process, the screw conveyor can gradually transport the winter rye in the storage box to the feed pipe, avoiding the compression caused by adding too much winter rye at one time, thereby greatly improving the initial screening efficiency of winter rye.

This structure can keep the stones and impurities from the initial screening on the screen box and make it easy to pour out. At the same time, the collection hopper at the bottom of the mounting frame can easily discharge the winter rye after initial screening into the collection drawer for collection, and this structure will not damage the screen box.

Because the screen box 805 is inserted into... On the moving frame 804, the electric push rod 803 on the mounting frame 801 quickly extends and retracts to push the moving frame 804 to roll back and forth on the mounting frame 801, so that the screen box 805 can quickly perform initial screening on the winter rye that falls from the feed pipe 3. This structure can keep the stones and impurities from the initial screening on the screen box 805 and make it easy to pour out. At the same time, the collection hopper 802 at the lower end of the mounting frame 801 can easily discharge the winter rye after initial screening into the collection drawer 11 for collection, and this structure will not damage the screen box 805.

[0026] refer to Figure 4 The inner side of the mounting frame 801 is symmetrically provided with wheel grooves 18. The moving frame 804 and the wheel grooves 18 are connected by a rolling mechanism.

The first support column 2 at the lower end of the housing 1 and the second support at the lower end of the connecting plate 501 can ensure the stable support of the device. The fixing plate 9 with fixing holes 10 at the lower ends of the first support column 2 and the second support column 502 can be used to fix the primary screening device.

[0029] refer to Figure 3The lower end of the screw conveyor 503 is symmetrically welded with connecting blocks 14, and the lower end of the connecting blocks 14 is welded with connecting seats 15. The connecting seats 15 on the right half of the lower end of the screw conveyor 503 are fixedly installed on the upper end of the connecting plate 501 by screws, and the connecting seats 15 on the left half of the lower end of the screw conveyor 503 are fixedly installed on the upper end of the housing 1 by screws. By using the connecting blocks 14 with connecting seats 15 welded to the lower end of the screw conveyor 503, the bolt conveyor can be easily installed and fixed on the housing 1 and the connecting plate 501.

[0030] refer to Figure 2 A placement seat 12 is fixedly installed on the inner side of the box body 1. A positioning groove 13 is opened on the side of the placement seat 12 facing the box door 6. The collection drawer 11 is inserted into the inner side of the positioning groove 13. An observation window 7 is provided on the inner side of the front of the box door 6. By using the placement seat 12 with the positioning groove 13 on the inner side of the box body 1, the collection drawer 11 can be easily positioned and inserted into the placement seat 12, so that the collection drawer 11 is directly below the opening of the collection hopper 802, which facilitates the collection of sieved winter rye.

[0031] Operating principle and advantages: During use, winter rye is first added to the storage box 505 through the feed inlet 504. Then, the stirrer is driven by the output end of the stirring motor 506 to stir in the storage box 505. In conjunction with the heating plate 507 in the storage box 505, the winter rye can be dehumidified. During the initial screening process, the screw conveyor 503 can gradually transport the winter rye in the storage box 505 to the feed pipe 3.

[0032] After the winter rye enters the mesh box 805 inside the box 1 through the feed pipe 3, the electric push rod 803 on the mounting frame 801 quickly extends and retracts to push the moving frame 804 to roll back and forth on the mounting frame 801, so that the mesh box 805 can quickly perform initial screening of the winter rye falling from the feed pipe 3. During the initial screening process, the dust and air raised by the screening mechanism 8 inside the box 1 can be sucked away and filtered by the vacuum cleaner 4. The stones and impurities of the initial screening are retained on the mesh box 805 and can be easily removed and cleaned by the handle 17. The winter rye after initial screening is discharged into the collection drawer 11 through the collection hopper 802 for collection. Then, the collection can be taken out by opening the box door 6.
