Description

An agricultural drum screen with spray cleaning function Technical Field

[0001] This utility model relates to the technical field of vegetable cleaning equipment, specifically an agricultural drum screen with spray cleaning function. Background Technology

[0002] In agricultural production, harvested agricultural products such as grains, vegetables, and fruits, as well as raw materials used in agricultural production such as seeds and fertilizers, often need to be screened and cleaned before entering the next stage of processing, storage, or sales. Screening can remove impurities and substandard products from the materials, ensuring product quality and purity; cleaning can remove dirt, dust, pesticide residues, etc. from the surface of the materials, improving the hygiene standards and safety of the products.

[0003] Traditional agricultural drum screens primarily function to screen materials, separating different sized items through the rotation of the drums and the action of the screen mesh. However, in actual agricultural production, materials not only need to be screened but also washed. Traditional drum screens lack washing capabilities, necessitating additional washing equipment and processes during material handling, increasing production costs and processing time. When processing vegetables, drum screens are first used to select appropriately sized vegetables, which are then transferred to washing equipment. This involves material handling and equipment switching, resulting in low efficiency and poor washing effects. Even some traditional drum screens equipped with simple washing devices often fail to achieve ideal cleaning results due to their inadequate design. Therefore, we propose an agricultural drum screen with a spray washing function to address these existing problems. Summary of the Invention

[0004] The purpose of this invention is to provide an agricultural drum screen with a spray cleaning function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an agricultural drum screen with spray cleaning function, comprising a base, a tilting mechanism and a drum screen, wherein a feeding cylinder is provided on the base, and the drum screen is movably connected to the feeding cylinder, and a tilting mechanism is provided on the side of the base near the drum screen, and a first guide groove and a second guide groove are provided on the surface of the drum screen, the tilting mechanism cooperates with the first guide groove and the second guide groove, and a mounting base is detachably provided on one side of the drum screen, and auxiliary wheels are symmetrically provided on the side of the base near the mounting base, the auxiliary wheels cooperate with the surface of the mounting base.

[0006] Preferably, the flipping mechanism includes a drive motor, a first synchronous pulley, a drive box, a synchronous belt, a drive rod, a bearing seat, a rotating rod, a second synchronous pulley, a spray head, a mounting groove, a drive wheel, a spray frame, a rotating gear disc, a limiting block, a guide groove, and a limiting block. The base has bearing seats symmetrically arranged on the side near the unloading cylinder. A rotating rod is movably connected to the bearing seat. A guide wheel is arranged on the rotating rod. The guide wheel cooperates with the first guide groove and the second guide groove. The base is fixedly connected to the drive motor. The output end of the drive motor is fixedly connected to the first synchronous pulley. A second synchronous pulley is arranged on the side of the rotating rod near the first synchronous pulley. A synchronous belt is sleeved between the first synchronous pulley and the second synchronous pulley.

[0007] Preferably, a spray frame is fixedly connected to the base, and a drive box is provided on the side of the base near the spray frame. An installation groove is provided inside the drive box, and a drive rod is movably connected inside the installation groove. A drive wheel is provided inside the installation groove on the drive rod, and a rotating gear disk is movably connected inside the spray frame. Limit grooves are provided on both sides of the rotating gear disk, and limit blocks are provided on both sides of the spray frame. The limit blocks are located on the limit grooves.

[0008] Preferably, spray heads are provided at equal intervals on the side of the rotating gear disk close to the drum screen, and the rotating gear disk and the drive wheel mesh with each other.

[0009] Preferably, a corrugated hose is provided on one side of the rotating gear disk, the rotating gear disk is connected to an external water supply device through the corrugated hose, and a connector is fixedly connected to the output end of the drive motor.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. When the drive motor starts, the second synchronous pulley will rotate together with the first synchronous pulley through the transmission action of the synchronous belt. The rotating rod will start to rotate under the support of the bearing seat. The guide wheel set on the rotating rod cooperates with the first guide groove and the second guide groove opened on the surface of the drum screen. When the rotating rod rotates, the guide wheel will roll along the first guide groove and the second guide groove, thereby driving the drum screen to rotate. This allows the drum screen to achieve regular rotation, which is convenient for screening agricultural materials in the screen and subsequent cleaning operations.

[0012] 2. The drive rod and connecting parts are coordinated by the adjusting block. The drive motor drives the drive wheel to rotate in the mounting slot inside the drive box, which in turn drives the rotating gear disk to rotate inside the spray frame. The limiting grooves on both sides of the rotating gear disk and the limiting blocks on both sides of the spray frame cooperate to ensure the stability of the rotating gear disk during rotation, allowing it to rotate smoothly. The spray head will also make a circular motion around the drum screen. The rotating gear disk is connected to the external water supply equipment through the corrugated hose. The water supplied by the external water supply equipment will be delivered to the rotating gear disk through the corrugated hose and then sprayed out by the spray head to spray and clean the drum screen and the agricultural materials inside the screen during the turning process, so as to achieve better cleaning and screening effects.
