Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of screening equipment, especially to the pasture seed screening equipment. BACKGROUND

[0002] Under the impetus of modern animal husbandry, the quality of pasture seeds is increasingly critical, which has given rise to pasture seed screening equipment. Seeds often mix with impurities and are prone to clumping during harvesting and storage, which seriously affects seeding quality, such as causing blockage of seeding machines and uneven seeding. At the same time, the process of standardizing seed quality is accelerating, and strict purity, cleanliness and other indicators need to be met. However, traditional manual screening is low in efficiency and poor in precision, and cannot meet the needs of large-scale production. Under this background, screening equipment has emerged as the times require. It can efficiently and accurately screen out impurities and unqualified seeds, ensuring seed quality and greatly improving agricultural production efficiency, and has become an indispensable part of modern pasture planting industry.

[0003] In the existing general pasture seed screening equipment, the screen for screening seeds is usually installed in the box by a fixed method. When the screen is clogged or needs to be cleaned, it is difficult to quickly disassemble it, which slows down the work efficiency of pasture seed screening. At the same time, in general screening equipment, the pasture seeds to be screened are directly put into the screening box during screening, which cannot fully scatter the clumped seeds, resulting in poor screening effect.

[0004] Based on this, the pasture seed screening equipment is provided, which can optimize the existing drawbacks of the device. UTILITY MODEL CONTENT

[0028] In this embodiment, the vibration generated by the operation of the vibration motor 19 makes the screening box 4 and the screen 10 vibrate together at a high frequency, so that the grass seeds placed on the screen 10 are effectively separated in a regular vibration environment. When the screen 10 needs to be checked, cleaned or replaced, the operator only needs to simply pull the pull plate 11 upwards, and the pull plate 11 will drive the movable rod 15 and the spring 26 fixedly connected thereto to move upwards, so that the lower end of the movable rod 15 is pulled out of the insertion hole 20 on the top of the connecting block 5. At this time, the connecting block 5 can be removed from the insertion slot 21, so that the screen 10 can be smoothly pulled out of the screening box 4 along the chute 23 in the middle part of the inner side of the fixed block 22. The operation is convenient.

[0029] Referring to Figure 2 and Figure 4 In a preferred embodiment, the scattering assembly includes a feed box 7, a servo motor 9 fixedly connected to the top right side of the top cover 6, the servo motor 9 is fixedly connected with the brush roller one 29 at the driving end, the brush roller one 29 is fixedly connected with the second transmission rod 28 at the left middle part, the second transmission rod 28 is fixedly connected with the second gear 17 at the left side, the second gear 17 is engagedly connected with the first gear 16, the first gear 16 is fixedly connected with the first transmission rod 27 at the right middle part, the first transmission rod 27 is fixedly connected with the brush roller two 30 at the left middle part, and the feed box 7 is provided with a feed inlet 8 at the top end.

[0030] In this embodiment, the seeds fed from the feeding port 8 fall into the feeding box 7 through the scattering assembly. The servo motor 9 is started to drive the brush roller I 29 at the driving end to rotate. The rotation of the brush roller I 29 drives the second gear 17 through the second transmission rod 28 fixedly connected at the middle left part. Since the second gear 17 is in meshing connection with the first gear 16, the first gear 16 rotates with the second gear 17, thereby driving the first transmission rod 27 fixedly connected at the middle right part of the first gear 16 to rotate the brush roller II 30 synchronously, and the rotation directions of the two are opposite. This mutual cooperation of the rotation modes makes the seeds in the feeding box 7 receive scattering forces from two directions, further enhances the scattering effect of the seeds, and improves the screening effect.
