Description

Device for making feed by using household food residues

Technical Field

The utility model belongs to waste classification handles and recycle field, concretely relates to device with domestic food waste preparation fodder.

Background

In daily life, the kitchen waste generally contains residues such as bones, shrimp shells, vegetable leaves, meat, rice grains, oil stains and the like, and many domestic pets are not suitable for feeding with food containing oil or excessive water, so the food residues are generally packaged and discarded when being treated, which not only causes food waste, but also brings great pressure to the environment-friendly work of cities.

At present, domestic pets mainly comprise cats and dogs, main components of cat foods and dog foods in the market generally comprise proteins, fats, vitamins, carbohydrates, water and the like, food residues on nutritional components completely meet the requirements of the pets, the dogs and the cats only do not eat vegetable leaves, but bones, shells and the like are difficult to swallow, and users who feed the pets generally need to prepare a plurality of special pet feeds, so that the great significance is achieved on how to prepare the pet feeds by utilizing the kitchen residues to reduce the feeding cost of the pets and protect the urban environment.

Disclosure of Invention

An object of the utility model is to provide a device with domestic food waste preparation fodder will cook and process into pet fodder with the incomplete thick soup leftovers of having a dinner in-process to reduce the waste of food, reduce urban pollution.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a device for preparing feed from domestic food residues comprises a grinding cavity, grinding and crushing rollers, an extrusion discharging roller, an extrusion cavity, support legs, a water receiving box and a feed box. The grinding chamber and the extrusion chamber are connected with the support legs, the grinding crushing roller is installed in the grinding chamber above the grinding chamber and connected with an external motor I through a shaft, the extrusion discharging roller is installed in the extrusion chamber below the extrusion chamber and connected with an external motor II through a shaft, the water receiving box is arranged in the middle of the support legs below the extrusion chamber, and the feed box is arranged below the rear end of the extrusion chamber.

The upper structure of the rolling cavity is horn-shaped, the lower structure is semicircular, knurling is arranged on the inner surface of the semicircular structure, and a plurality of discharging holes with the diameter of phi 5mm are designed on the semicircular structure.

The axis of the rolling and crushing roller wheel is concentric with the circle center of the semi-circular surface of the rolling cavity, hob grooves with the same interval are formed in the rolling and crushing roller wheel, and the minimum gap between the outer circular surface of the hob groove and the inner surface of the semi-circular surface of the rolling cavity is 3-4 mm. The reason for this is: the grinding roller is beneficial to crushing large hard food residues added into the grinding cavity into small blocks with the diameter of less than 4mm under the grinding and friction of the hob groove and the knurls, and discharging the small blocks from the discharge hole.

The extrusion discharging roller is spiral and is arranged in the cylindrical extrusion cavity and concentric with the extrusion discharging roller, and the pitch between adjacent spiral structures on the extrusion discharging roller is gradually reduced from top to bottom. The reason for this is: the broken small food residues are gradually pushed to the rear end under the action of the screw, and the extrusion degree of the food residues is larger and larger due to the continuous reduction of the screw pitch, so that the food residues are more beneficial to the dehydration of water and the next granulation.

The lower cylindrical surface of the extrusion cavity is provided with a drain hole with the diameter phi of 1mm, the end surface of the tail part is provided with a forming hole with the length of 8-10mm and the diameter of 6-8mm, and a scraping rod connected with a shaft is arranged outside the forming hole in a close fit manner. The reason for this is: food residues are continuously extruded, internal water is discharged into the water receiving box from the water discharge hole, solid residues are extruded out from the forming hole, and the solid residues fall into the feed box after being cut by the scraping rod.

Fig. 3 is a sectional view of the internal structure of the present invention.

Wherein: 1 grinding chamber, 2 grinding crushing roller, 3 extruding discharging roller, 4 extruding chamber, 5 support legs, 6 water receiving box, 7 feed box, 101 discharging hole, 201 motor I, 301 motor II, 401 water discharging hole, 402 forming hole and 403 scraping rod.

Detailed Description

The invention will be further described in the following preferred embodiments with reference to fig. 3:

referring to fig. 3, which is a sectional view showing the structure of the embodiment, the device for preparing feed from household food waste comprises a grinding chamber 1, a grinding and crushing roller 2, an extrusion discharging roller 3, an extrusion chamber 4, support legs 5, a water receiving box 6 and a feed box 7. The grinding chamber 1 and the extrusion chamber 4 are both connected with the support leg 5, the grinding crushing roller 2 is arranged in the grinding chamber 1 above and is connected with the first external motor 201 through a shaft, and the extrusion discharging roller 3 is arranged in the extrusion chamber 4 below and is connected with the second external motor 301 through a shaft.
