[0025] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the utility model.

[0026] Embodiment one

[0027] The prior art utilizes vibration screening, which can affect the overall screening of dog food and produce certain noise. The present embodiment provides a drying and screening device for dog food production, which can perform semi-rolling screening on dog food and prevent dog food from piling up during the screening process, thereby improving the screening efficiency of dog food and reducing the noise generated during screening. Figures 1-4 The drying and screening device for dog food production includes a feed hopper 2 mounted at the top end of a screening box 1 and two groups of dryers 3 mounted on the screening box 1. Two groups of guide plates are installed at the connection between the feed hopper 2 and the screening box 1 to reduce the pressure generated by the falling dog food. The two groups of guide plates are distributed in the interior of the connection between the feed hopper 2 and the screening box 1 in a staggered manner, thereby making the flow of dog food more stable and playing a protective role on the dog food. A cleaning mechanism 4 for cleaning the screened dog food is arranged inside the screening box 1, and a screening mechanism 5 for screening the dog food is arranged inside the screening box 1. The cleaning mechanism 4 can automatically clean the screened dog food, improving the production efficiency of dog food. The screening mechanism 5 can stably screen the dog food and prevent the dog food from piling up during the screening process, thereby improving the screening effect of dog food.

[0028] In the process of screening dog food, in order to prevent the accumulation of dog food from affecting the screening effect and improve the production efficiency of dog food, the screening mechanism 5 includes a fixed frame 51 installed inside the screening box 1, a screening piece 52 rotatably connected to the fixed frame 51, a gear 53 installed on the connecting end of the screening piece 52, and a plurality of arc-shaped grooves 54 formed on the inner side of the screening piece 52. The shape of the arc-shaped groove 54 is similar to the shape of the side of the screening piece 52, so that the dog food is dispersed by the material dispersing scraper 55 to avoid the dog food from piling up together. The arc-shaped groove 54 is slidably connected with the material dispersing scraper 55 which abuts against the inner side of the screening piece 52. The material dispersing scraper 55 is symmetrically distributed on both sides of the screening piece 52, which improves the dispersing effect of the dog food. A load-bearing plate 56 is installed inside the screening box 1. An electric push rod 57 is installed on the screening box 1. A rack 58 is slidably connected with the load-bearing plate 56 and is engaged with the gear 53. The length of the rack 58 is less than the length of the load-bearing plate 56, so as to prolong the running length of the rack 58 and improve the screening effect of the dog food. The rack 58 and the gear 53 are symmetrically distributed on both sides of the screening piece 52, which makes the back-and-forth rotation of the screening piece 52 more stable. A buffer assembly 501 is arranged on the fixed frame 51 to reduce the pressure generated by the rotation of the screening piece 52. Through the extension and retraction of the electric push rod 57, the rack 58 moves back and forth under the support of the load-bearing plate 56. Under the connection of the gear 53, the screening piece 52 rotates back and forth under the support of the fixed frame 51, so as to screen the dog food as a whole. Under the back-and-forth rotation of the screening piece 52, the material dispersing scraper 55 moves back and forth under the support of the arc-shaped groove 54 due to the effect of inertia, which prevents the dog food from piling up together and improves the screening effect of the dog food.

[0029] In the process of screening dog food, in order to make the rotation of the screening piece 52 more stable, the buffer assembly 501 includes a plurality of buffer springs 5011 installed on the fixed frame 51. A buffer plate 5012 is installed on the buffer spring 5011. A stop plate 5013 corresponding to the position of the buffer plate 5012 is installed on the screening piece 52. Under the back-and-forth rotation of the screening piece 52, the stop plate 5013 constantly contacts the buffer plate 5012. Under the elastic effect of the buffer spring 5011, the rotation of the screening piece 52 is more stable, which improves the stability of the screening.

[0030] Example Two

[0031] Based on example one, as shown in Figures 1-4 , based on the existing problem of using vibration screening in the prior art which affects the overall screening of dog food and produces certain noise, but after screening the dog food, the screened dog food is usually collected by manual cleaning, which easily reduces the production rate of dog food. Therefore, the device is also provided with a structure for automatically cleaning the screened dog food.

[0032] In the process of screening dog food, in order to quickly and automatically clean and collect the dog food, improve the production efficiency of dog food, the material cleaning mechanism 4 includes a driving motor 41 installed on the screening box 1, the output end of the driving motor 41 is connected with a rotating rod 42, the rotating rod 42 is threadedly connected with a mounting seat 43, the screening box 1 is internally provided with a circular rod 44 penetrating through the mounting seat 43, the mounting seat 43 is provided with a material pushing plate 45 abutting against the bottom end of the screening box 1, the mounting seat 43 is provided with a side wall scraping plate 46 abutting against the inner wall of the screening box 1 at both ends, the screening box 1 is provided with two groups of clamping sleeves 47, the clamping sleeves 47 are slidably connected with sealing door plates 48 abutting against the side edges of the screening box 1. The driving motor 41 drives the rotating rod 42 to rotate, and under the limiting support of the circular rod 44, the mounting seat 43 moves back and forth on the rotating rod 42, so as to drive the material pushing plate 45 to quickly clean the screened dog food, and the movement of the mounting seat 43 can also drive the side wall scraping plate 46 to clean the residual material adhered to the inner wall of the screening box 1, thereby enhancing the production quality of the dog food.
