Description

Technical Field

[0001] This utility model relates to the field of agricultural screening machinery technology, specifically to a vibrating screening machine for Chinese medicinal materials that ensures they are not damaged, broken, or broken, and are arranged neatly. Background Technology

[0002] Harvesting root and rhizome medicinal herbs requires digging them out of the soil, a traditional method that involves manually picking and removing the soil, which is time-consuming and labor-intensive. Currently, agricultural tractors are often used to tow harvesters for short-rooted medicinal herbs that are not susceptible to damage to the outer skin. Structurally, medicinal herb harvesters include a frame, digging shovel, and conveying and screening devices. The conveying and screening devices feature a chain conveyor structure, utilizing the gaps between the chain plates to remove soil. However, existing medicinal herb harvesters tend to break, crack, and damage the outer skin of long-rooted medicinal herbs when harvesting them, reducing both the yield and quality of the herbs.

[0003] For Chinese medicinal herbs with long rhizomes and fragile skin, especially those harvested as seedlings (such as Astragalus membranaceus seedlings) which are relatively long (50-80cm), the seedlings cannot be planted once the skin is damaged, broken, or fractured.

[0004] Therefore, in response to the aforementioned technical problems, the applicant has researched and designed a vibrating sieve machine for Chinese medicinal materials based on existing vibrating sieve devices. After long-rooted Chinese medicinal materials are dug up, the machine can quickly separate the soil from the medicinal materials, saving time spent on manual picking, improving work efficiency, and reducing planting costs. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the above-mentioned technology and provide a vibrating screen for Chinese medicinal materials. The purpose is to move the entire vibrating screen device forward by towing it with a tractor, and use the vibrating screen to separate the soil from the roots of the Chinese medicinal materials. Using the vibrating screen will not easily damage the skin of the medicinal materials, will not break them, and will arrange them neatly. With the soil separating plate being higher in the front and lower in the back and the soil discharge plate being inclined, the soil will be automatically discharged from the soil discharge plate under the action of this vibration, achieving the technical effect of quickly separating the soil without breaking or damaging the skin. This solves the technical problem that existing Chinese medicinal material harvesters cannot screen out long Chinese medicinal materials completely and in whole pieces.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a vibrating sieve for Chinese medicinal materials, including a frame and traveling wheels rotatably arranged at the bottom of both sides of the frame, and a vibrating sieve and a soil separating plate arranged vertically on the frame;

[0007] The vibrating screen has several screen holes on its screen surface and a feed plate at its rear end. A soil retaining plate is inserted and connected to the rear end of the feed plate. The vibrating screen is set above the soil separating plate and is inclined with the front higher than the back.

[0008] The soil distribution plate has symmetrical soil discharge plates on both sides of its rear end. The soil discharge plates are inclined and are used to discharge the soil from the soil distribution plate. The soil distribution plate is inclined with the front end higher than the rear end.

[0009] Furthermore, the cross-section of the soil dividing plate is inverted V-shaped, which forms a T-shaped structure with the soil exiting plates symmetrically arranged on both sides of the rear end. The end of the soil exiting plate closer to the soil dividing plate is higher than the other end.

[0010] Furthermore, the vibrating screen and the soil separating plate are fixedly connected as an integrated unit. An eccentric vibrating shaft is horizontally arranged below the soil separating plate and rotatably connected thereto. A drive device is arranged on one side of the frame. The output end of the drive device is connected to the eccentric vibrating shaft through a clutch. The drive device drives the eccentric vibrating shaft to rotate, thereby causing the vibrating screen and the soil separating plate to vibrate. Shock absorbers are respectively arranged at the four corners of the lower end of the soil separating plate, and the lower ends of the shock absorbers are fixedly connected to the frame.

[0011] Furthermore, the sieve holes are arranged in a staggered pattern, which is used to sieve the vibrated soil onto the soil separating plate.

[0012] Furthermore, the feed plate is inclined, and slots are provided on both sides of its tail end, with the retaining plate slidingly inserted into the slots.

[0013] The advantages of this invention compared to existing technologies are as follows: This invention separates soil from medicinal herbs using a vibrating screen, and then discharges the soil through a soil separating plate and a soil discharge plate; the medicinal herbs are discharged from the vibrating screen through a feeding plate, completing the sieving and discharge of soil from the root and stem medicinal herbs, allowing the soil to be separated quickly without breaking or damaging the bark. The specially designed soil separating plate and soil discharge plate can quickly discharge the soil, and the staggered sieve holes can effectively sift out the soil. This invention has a reasonable structural design, can be used with a tractor for sieving on-site, is convenient to use, and has strong practicality. Attached Figure Description

[0022] Example 1:

[0023] Combined with appendix Figure 1 , 2 A vibrating sieve for Chinese medicinal materials includes a frame 1, rotatable wheels 2 at the bottom of both sides of the frame 1, and a vibrating sieve 3 and a soil separating plate 4 arranged vertically on the frame 1.

[0024] The vibrating screen 3 has a number of screen holes 301 on its screen surface, and a feed plate 6 is provided at its rear end. A soil retaining plate 7 is provided at the rear end of the feed plate 6 and is inserted and connected to it. The vibrating screen 3 is located above the soil separating plate 4 and is inclined with the front higher than the back.

[0025] The soil distribution plate 4 has symmetrically arranged soil discharge plates 5 on both sides of its rear end. The soil discharge plates 5 are inclined and are used to discharge soil from the soil distribution plate 4. The upper plate of the soil distribution plate 4 is inclined with the front higher than the rear. The soil discharge plates at both ends of the rear side of the soil distribution plate extend to both sides to facilitate the backfilling of soil into the excavator's chemical pit.

[0026] In a preferred embodiment, the soil separating plate 4 has an inverted V-shaped cross-section, forming a T-shaped structure with the soil discharge plates 5 symmetrically arranged on both sides of the rear end. The end of the soil discharge plate 5 closest to the soil separating plate 4 is higher than the other end. The vibrating screen 3 and the soil separating plate 4 are integrally and fixedly connected vertically. An eccentric vibrating shaft 401 is horizontally arranged below the soil separating plate 4 and rotatably connected to it. A drive device 9 is located on one side of the frame 1. The output end of the drive device 9 is connected to the eccentric vibrating shaft 401 via a clutch. The drive device 9 drives the eccentric vibrating shaft 401 to rotate, thereby vibrating the vibrating screen 3 and the soil separating plate 4. This drive device can be a diesel engine.

[0027] Shock absorbers 8 are respectively installed at the four corners of the lower end of the soil separating plate 4, and the lower ends of the shock absorbers 8 are fixedly connected to the frame 1. A start button connected to the drive device 9 is installed on the frame 1 to start and stop the vibrating screen 3 at any time. The start button, i.e., the switch, is located in a relatively safe position, away from the diesel engine.

[0028] In a preferred embodiment, the sieve holes 301 are arranged in a staggered pattern, used to sieve the vibrated soil onto the soil separating plate 4. The sieve holes 301 are drilled from manganese steel plates, resulting in a smooth sieve surface that minimizes friction between the sieve surface and the medicinal materials, thus preventing damage to the surface of the medicinal materials.

[0029] In a preferred embodiment, the feeding plate 6 is inclined, with slots on both sides of its tail end, and the retaining plate 7 is slidably inserted into the slots. When feeding, the retaining plate 7 is pulled out, allowing the medicinal materials to be discharged from the vibrating screen 3 through the feeding plate 6, thus completing the separation of the medicinal materials from the soil.

[0030] In a specific implementation of this utility model, a connecting joint can be provided at the front end of the frame 1. The connecting joint is connected to the tractor through a coupling (this connection method is a common load connection device, which will not be described in detail here).

[0031] Continuing from the above, in the specific implementation of this utility model, the vibrating screen and the soil separating plate are arranged parallel and inclined to each other. A tractor connects and drags the entire device to move it in the field. When the medicinal materials with soil reach the vibrating screen 3, the soil falls off the medicinal materials under the vibration of the vibrating screen 3, passes through the screen holes 301 and falls onto the soil separating plate 4. The soil is discharged from the discharge plate 5 under its own weight and the action of vibration. The medicinal materials after the soil separation are discharged through the feeding plate 6. The traveling wheels move freely under the traction of the tractor.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
