[0041] like Figures 1 to 8 As shown, this specific embodiment uses a vertical adjustment method to adjust the height of the feeding trough 3-1. Specifically, it employs the following technical solution: it includes a base 1 and an adjustable support frame 2; the adjustable support frame 2 is installed on the upper surface of the base 1, as shown... Figure 2As shown, the adjustable support frame 2 includes a support frame 2-1, a lead screw 2-2, an adjusting seat 2-3, an adjusting motor 2-4, a support column 2-5, and a support plate 2-6. A recessed mounting groove 2-11 is provided on the front side wall of the support frame 2-1. The bottom of the support frame 2-1 is connected to the base 1. The lead screw 2-2 is mounted in the mounting groove 2-11 via a bearing. The lead screw 2-2 is connected to the threaded hole of the adjusting seat 2-3 via a thread. The adjusting seat 2-3 is movably connected to the mounting groove 2-11. An adjusting motor 2-4 is installed at the upper end of the support frame 2-1. The adjusting motor 2-4 can drive the lead screw 2-2 to rotate. When the lead screw 2-2 rotates, the adjusting seat 2-3 can move up and down, which facilitates the up and down adjustment of the cleaning feeding trough mechanism 3. The rotating shaft of the adjusting motor 2-4 is connected to the upper end of the lead screw 2-2. Support columns 2-5 are installed at the four corners of the upper end of the support frame 2-1. Support plates 2-6 are installed at the upper ends of the four support columns 2-5. The support plates 2-6 can realize the installation of the quantitative feeding mechanism 4.

[0042] like Figure 1 As shown, in this specific embodiment, cleaning is achieved through a cleaning-type feeding trough mechanism 3, which ensures the cleanliness of the feeding trough. The specific technical solution is as follows: It includes a cleaning-type feeding trough mechanism 3, which is mounted on an adjustable support frame 2.

[0044] As stated above, Figure 5 As shown, in this specific embodiment, when cleaning the feeding trough is required, it is achieved through scraping and washing. The specific structure is as follows: the washing scraper body 3-2 includes a scraper 3-21, a connecting end 3-22, a scraping rubber sheet 3-23, and a washing pipe 3-24; both upper ends of the scraper 3-21 are integrally connected to the connecting end 3-22, which can be connected to the steel wire 3-5, facilitating the movement of the scraper 3-21 via the steel wire 3-5. A scraping rubber sheet 3-23 is installed on the outer wall of the scraper 3-21, enabling cleaning of the inner wall of the feeding trough. A washing pipe 3-24 is installed at the inner edge of both the inner and outer walls of the scraper 3-21, and the washing pipe 3-24 is equipped with a water spray nozzle, which cleans the inner wall of the feeding trough. Figure 6 As shown, a connecting block 3-51 is installed on the steel wire 3-5, and the connecting block 3-51 can be connected to the connecting end 3-22.

[0045] like Figure 1 As shown, in this specific embodiment, quantitative feeding is achieved through a quantitative feeding mechanism, which saves feed and facilitates feeding. The specific technical solution adopted is as follows: It includes a quantitative feeding mechanism 4; the quantitative feeding mechanism 4 is installed on the top of the adjustable support frame 2, and cooperates with the cleaning-type feeding trough mechanism 3. Quantitative feeding is achieved using the quantitative feeding mechanism 4, as shown... Figure 7 As shown, the quantitative feeding mechanism 4 includes a storage bin 4-1, a guide plate 4-2, a feeding pipe 4-3, a quantitative feeding roller mechanism 4-4, and a quantitative motor 4-5. Several guide plates 4-2 are installed inside the storage bin 4-1, which can realize rapid material feeding. The guide pipe 4-2 is a V-shaped plate, and the feeding pipe 4-3 is connected to the bottom center of the guide plate 4-2, which can realize material feeding. The quantitative feeding roller mechanism 4-4 is installed inside the feeding pipe 4-3. The shaft of the quantitative motor 4-5 is connected to the quantitative feeding roller mechanism 4-4. The quantitative motor 4-5 is installed on the outer side wall of the feeding pipe 4-3. The quantitative feeding roller mechanism 4-4 can realize quantitative feeding, which facilitates quantitative feeding.

[0046] As described above, the structure of the quantitative feeding roller mechanism in this specific embodiment is as follows: the quantitative feeding roller mechanism 4-4 includes a feeding roller 4-41, feeding blades 4-42, and sealing gaskets 4-43; several feeding blades 4-42 are evenly installed on the outer side wall of the feeding roller 4-41, and the feeding roller 4-41 drives the several feeding blades 4-42 to rotate, which can realize rapid feeding. Sealing gaskets 4-43 are installed on the outer side wall of the feeding blades 4-42, and the front and rear side walls of the feeding roller 4-41 and the sealing gaskets 4-43 are sealed with the inner side wall of the feeding pipe 4-3, and the sealing method is used to prevent material leakage when stopped.

[0047] like Figure 1 As shown, in order to improve the stability of the cleaning feeding trough mechanism during adjustment, the following technical solution is adopted in this specific embodiment: it includes a fixed plate 5 and a guide rod 6; the lower ends of both sides of the quantitative feeding mechanism 4 are equipped with fixed plates 5, and the bottom of the fixed plates 5 is equipped with guide rods 6. The guide rods 6 are movably connected to the cleaning feeding trough mechanism 3, and the guide rods 6 are used to achieve guidance. The guide rods 6 are movably connected to the guide sleeves 3-6, and can move within the guide sleeves 3-6, thereby improving the stability of the cleaning feeding trough mechanism 3 when moving up and down.

[0048] The working principle of this specific embodiment is as follows: During use, the base 1 provides fixation. After fixation, material is loaded into the storage box 4-1 of the quantitative feeding mechanism 4. After loading, the height is adjusted according to the required feeding height by using the adjustable support frame 2 to drive the cleaning feeding trough mechanism 3. During adjustment, the adjusting motor 2-4 drives the lead screw 2-2 to rotate. The adjusting seat 2-3 on the lead screw 2-2 can move the feeding trough 3-1 up and down, thus adjusting the feeding height. After the height adjustment is complete, quantitative feeding is achieved through the quantitative feeding mechanism 4. During quantitative feeding, the quantitative... Motor 4-5 drives the quantitative feeding roller mechanism 4-4 to rotate to achieve quantitative feeding. When it stops, its feeding roller 4-41 and feeding blade 4-42 can seal the feeding pipe 4-3 to facilitate stopping feeding. When it is necessary to clean the feeding tank 3-1, the plug plate 3-13 is pulled out first. The drive motor 3-3 drives the wire wheel 3-4 to rotate, so that the wire 3-5 can drive the cleaning scraper plate 3-2 to move. The scraping rubber sheet 3-23 of the scraper plate 3-21 is used for scraping. At the same time, the cleaning pipe 3-24 can clean the inner wall. Finally, it is discharged from the discharge tank 3-11.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0050] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
