Technical Field
[0001] This utility model relates to the field of forestry seed technology, specifically to a seed screening and drying device for forestry planting. Background Technology
[0002] Forestry planting refers to production and management activities that involve the artificial cultivation, planting, and management of forest vegetation (including trees, shrubs, bamboo, etc.) to achieve multiple goals such as ecological protection, economic output, and social benefits. It is the core link of the forestry industry, involving the entire chain of management from seedling cultivation to timber harvesting and utilization, and at the same time undertaking important ecological functions such as maintaining ecological balance and responding to climate change.
[0003] According to Chinese patent document CN220295152U, a seed screening and drying device for forestry planting includes a screening device, a feeding device at the top of the screening device, and a drying device on the screening device. This utility model provides a seed screening and drying device for forestry planting. The feeding device temporarily stores seeds for forestry planting in a feeding hopper. The screening device, with an auger continuously conveying the seeds, filters them through a sieve cylinder. Simultaneously, the drying device, with a hot air blower, dries the seeds. This device has a simple structure and can simultaneously screen and dry seeds for forestry planting. The continuous movement of the seeds during auger conveying improves the screening and drying efficiency.
[0004] The device described in the aforementioned literature may have several drawbacks during use. For example, the auger may compress the seeds during seed transport, causing small sieve holes to become clogged by large seeds, thus affecting sieving efficiency. Relying solely on the auger for seed transport results in poor seed flowability and insufficient sieving. Furthermore, blowing hot air from only one end may lead to insufficient temperature at the end. Utility Model Content

[0023] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:
[0024] like Figure 1 As shown, this utility model provides a seed screening and drying device for forestry planting, including a support shell 1, a support leg 2 fixedly connected to the bottom of the support shell 1, a drying cylinder 3 fixedly connected inside the support shell 1, a feeding component 4 placed at the bottom of the drying cylinder 3, a support frame 6 provided at the tail of the feeding component 4, a vibration motor 5 fixedly connected to the middle of the support frame 6, and a screening box 7 fixedly connected to the top of the vibration motor 5.
[0025] like Figure 2 and 3As shown, the drying cylinder 3 includes a drying chamber 31. A feed inlet 32 is provided at the top of the drying chamber 31. A condenser pipe 33 is fixedly connected to the top of the drying chamber 31. Several stirring shafts 37 are rotatably connected inside the drying chamber 31. A synchronous belt 38 is rotatably connected between the stirring shafts 37. A rotary motor 36 is fixedly connected to the tail of one of the stirring shafts 37. Two sets of stirring blades 371 with different angles are fixedly connected to the middle of the stirring shaft 37. A heating wire 35 is provided between the support shell 1 and the drying chamber 31. A discharge port 311 is opened at the bottom of the drying chamber 31. A discharge valve 34 is fixedly connected to the bottom of the drying chamber 31. A valve plate 342 is rotatably connected inside the discharge valve 34. A gate 343 is threadedly connected to the tail of the valve plate 342. A handle 341 is fixedly connected to the head of the valve plate 342. Seeds are placed into the drying chamber 31 through the inlet 32. The heating wire 35 brings the drying chamber 31 to a certain temperature to dry the seeds. The rotary motor 36 drives a stirring shaft 37 and stirring blades 371 to rotate. The remaining stirring shaft 37 and stirring blades 371 are driven to rotate synchronously by the synchronous belt 38. During the falling process, seeds that are stuck together are broken up by the rotating stirring blades 371, improving drying efficiency. At the same time, the stirring blades 371 drive the gas in the drying chamber 31 to rotate, making the internal temperature more uniform. The condenser 33 set at the top uses existing technology to condense the water vapor formed by high-temperature evaporation in the drying chamber 31 into water and discharge it to the outside of the drying chamber 31, avoiding water droplets on the inner wall of the drying chamber 31 from affecting the drying effect. The dried seeds are discharged uniformly through the discharge valve 34.
[0026] like Figure 4As shown, the feeding component 4 includes a rotating leg 41. Both ends of the inner wall of the rotating leg 41 are rotatably connected to a rotating shaft 44.

[0030] The working principle of this utility model is as follows: the seeds are placed into the drying chamber 31 through the feed inlet 32, and the temperature inside the drying chamber 31 is raised by the heating wire 35 to dry the seeds. The stirring blades 371 break up the sticky seeds, and the condenser tube 33 condenses the water vapor into water and discharges it to improve the drying efficiency of the seeds. After further drying, the seeds are screened. The vibrating motor 5 can drive the screening plate 74 to vibrate, which can improve the fluidity of the seeds, increase the screening efficiency, and reduce the risk of screen blockage. The inclined baffle 741 can play an isolation role in the screening process to prevent small seeds from being screened out through the large holes at the back due to excessive fluidity, which would affect the screening effect.
