Description

Technical Field

[0001] This utility model relates to the field of bellflower harvester technology, specifically a conveying and screening mechanism for harvesting bellflowers. Background Technology

[0002] The Platycodon grandiflorus harvester is an agricultural machine specifically designed for harvesting the roots and stems of the Chinese medicinal herb Platycodon grandiflorus. By replacing traditional manual digging with mechanized operations, it significantly improves harvesting efficiency and reduces labor intensity. The Platycodon grandiflorus harvester uses a shovel, vibrating, or rotating digging head to penetrate deep into the soil (usually 20-40cm deep, matching the soil penetration characteristics of Platycodon grandiflorus roots and stems). After uprooting the Platycodon grandiflorus, the roots and stems are separated from the soil and leaves by a conveyor belt, vibrating screen, and other sorting devices.

[0003] Existing bellflower harvesters have soil-crushing rollers at the top of their screens, but the pressing height of these rollers is not easily adjustable to suit the needs of different usage scenarios. Therefore, we propose a conveying and screening mechanism for bellflower harvesting. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows: A conveying and screening mechanism for harvesting bellflowers includes: a main body and a soil-crushing component; the main body includes a casing and a screen movably installed inside the casing; the soil-crushing component includes a soil-crushing frame movably installed on both sides inside the casing, mounting openings on both sides of the soil-crushing frame, a pressure roller movably installed in the soil-crushing frame, a fixing block fixedly installed on both sides of the pressure roller, toothed grooves arranged on one side of the fixing block, toothed plates movably installed in the mounting openings, and threaded holes on both sides of the soil-crushing frame. Preferably, each of the threaded holes is also movably fitted with a locking screw. Preferably, a fixing sleeve is fixedly installed on one side of the toothed plate, and the locking screws are movably installed inside the fixing sleeve. Preferably, both ends of the soil crushing frame are fixedly installed with fixed shafts, and the fixed shafts are movably installed in the machine housing. A sprocket is also fixedly installed on the outer end of the fixed shaft on one side of the soil crushing frame. Preferably, a chain is also meshed on the sprocket, and an electric motor is fixedly installed on the outer end of the sprocket on one side of the soil crushing frame. Preferably, a fixing frame is also fixedly installed on the outer end of the motor, and the fixing frame is fixed to the chassis.

[0006] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. In this utility model, the soil crushing frame installed on both sides inside the machine box can crush larger soil clods during conveying by rotating the inner pressure roller on the screen under the transmission of the sprocket and chain driven by the motor, thereby separating them from the stalks and improving the screening effect of the stalks. 2. In this utility model, the pressing height of the pressure roller inside the soil crushing frame can also be flexibly adjusted according to usage requirements to suit different usage scenarios.

Detailed Implementation

[0009] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0010] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a conveying and screening mechanism for harvesting bellflowers.

[0011] Example 1: Combination Figure 1-4As shown, this utility model provides a conveying and screening mechanism for harvesting and processing *Platycodon grandiflorus*, comprising: a main body 100 and a soil-crushing component 200; the main body 100 includes a housing 101 and a screen 102 movably installed inside the housing 101; the soil-crushing component 200 includes a soil-crushing frame 201 movably installed on both sides inside the housing 101, mounting openings 202 on both sides of the soil-crushing frame 201, pressure rollers 203 movably installed in the soil-crushing frame 201, fixing blocks 204 fixedly installed on both sides of the pressure rollers 203, toothed grooves 205 arranged on one side of the fixing blocks 204, toothed plates 206 movably installed in the mounting openings 202, and threaded holes 207 on both sides of the soil-crushing frame 201. Each threaded hole 207 is also movably installed with a locking screw 208. Each toothed plate 206 is also fixedly installed with a fixing sleeve 209, and the locking screw 208 is movably installed in the fixing sleeve 209. Each end of the soil crushing frame 201 is also fixedly installed with a fixing shaft 210, and the fixing shaft 210 is movably installed in the machine housing 101. Each fixed shaft 210 on one side of the soil crushing frame 201 is also fixedly installed with a sprocket 211, and a chain 212 is also meshed on the sprocket 211. Each sprocket 211 on one side of the soil crushing frame 201 is also fixedly installed with a motor 213, and a fixing bracket 214 is fixedly installed on the outer end of the motor 213, and the fixing bracket 214 is fixed to the machine housing 101.

[0012] Specifically, the Platycodon grandiflorus harvester is an agricultural machine specifically designed for harvesting the rhizomes of the medicinal herb Platycodon grandiflorus. The main body 100 of this device has a soil-crushing frame 201 installed on both sides inside the casing 101. Driven by a sprocket 211 and chain 212 driven by a motor 213, the inner pressure roller 203 rotates above the screen 102, crushing larger clods of soil during transport and separating them from the Platycodon grandiflorus, thus improving the screening effect. Simultaneously, the pressing height of the inner pressure roller 203 of the soil-crushing frame 201 can be flexibly adjusted according to usage requirements, catering to different soil clod sizes and application scenarios. The soil-crushing frame 201 has openings 2 on both sides. The toothed plate 206, tightened by the locking screw 208 in section 02, is mainly used to tighten the fixing blocks 204 on both sides of the pressure roller 203 to ensure its stability. At the same time, by loosening the toothed plate 206 by the locking screw 208, the fixing blocks 204 on both sides of the pressure roller 203 can be released, thereby adjusting the position of the pressure roller 203 in the soil crushing frame 201. The fixing sleeve 209 installed on one side of the toothed plate 206 is mainly used to strengthen the connection between the toothed plate 206 and the locking screw 208, and to prevent the reinforcing toothed plate 206 from detaching through the mounting port 202. The fixing bracket 214 at the outer end of the motor 213 is mainly used to ensure the stability of the motor 213.

[0013] Working principle and usage process of this utility model: During operation of the screen 102 inside the housing 101, the sprocket 211 and chain 212 driven by the motor 213 rotate the soil crushing frame 201 on both sides of the screen 102. As the soil crushing frame 201 rotates, the pressure rollers 203 at its inner end will press the soil clods on the screen 102 when they rotate to the upper end of the screen 102, so as to crush the soil clods and pass them through the screen 102. The rotating pressure rollers 203 can also press the stalks and separate the soil clods adhering to their upper ends, thereby ensuring the screening effect of the stalks. At the same time, in different regions or scenarios, the locking screws 208 at both ends of the soil crushing frame 201 can be loosened according to the size of the soil clods to flexibly and conveniently adjust the pressing height of the pressure rollers 203 inside the soil crushing frame 201, so as to improve its applicability in use.

[0014] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
