Description

Technical Field

[0001] The invention relates to the technical field of pet feed mixing, in particular to a pet feed ingredient mixing device. Background Art

[0002] Pet feed is usually a mixture of various natural and synthetic ingredients, including meat, grains, vegetables, fats, vitamins and minerals. These ingredients are scientifically proportioned to ensure that they can provide pets with balanced nutrition to support their growth, immune system, hair health, bone development and other needs. In the production process of pet feed, the mixing uniformity of ingredients not only affects the quality and nutritional content of the feed, but is also directly related to the taste, digestibility and health of the pet.

[0003] Existing mixing devices for mixing pet feed ingredients usually include components such as a mixing drum and a mixing device. The ingredients are introduced from a feed pipe and then stirred by the stirring device to achieve mixing of the pet feed ingredients. However, since the feed pipe is fixed in this method, when adding ingredients, the ingredients are easily accumulated in one place of the mixing drum, thereby forming a concentration gradient. Although the stirring device can be used to achieve uniform stirring later, the time required is long and the effect is not good. At the same time, the ingredients of pet feed may contain meat powder, etc., which are usually viscous and easy to be blocked in the feed pipe, thereby causing production to stop.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 3The present invention provides a technical solution: a pet feed ingredient mixing device, comprising a frame 101, a mixing drum 102 is installed on the frame 101, a discharging pipe 103 is connected to the lower end of the mixing drum 102, a valve is arranged on the discharging pipe 103, a box 105 is fixedly connected to the upper part of the mixing drum 102 through a connecting rod 104, a third motor 106 is installed in the box 105, a driving shaft 107 is fixedly connected to the output shaft of the third motor 106, a stirring assembly for mixing feed ingredients is installed on the driving shaft 107, a reciprocating thread 1071 is arranged on the upper end of the driving shaft 107, a truncated cone block 108 is threadedly connected to the driving shaft 107, the diameter of the truncated cone block 108 is large at the upper end and small at the lower end, a spray assembly for spraying water on the feed ingredients is installed in the box 105, and the spray assembly is connected to the truncated cone block 108; The upper end of the mixing drum 102 is open, and the upper end of the mixing drum 102 is sealed and rotatably connected to the rotating drum 201. The mixing drum 102 is sleeved on the outside of the box 105. The rotating drum 201 is driven by a driving assembly to realize rotation. The driving assembly includes a gear ring 601, a gear 602 and a first motor 603. The upper end of the rotating drum 201 and the upper end of the mixing drum 102 are arranged with a gap. The gear ring 601 is fixedly connected to the outer wall of the rotating drum 201. The first motor 603 is installed on the outer wall of the mixing drum 102. The gear 602 is fixedly connected to the output shaft of the first motor 603. The gear 602 and the gear ring 601 are meshed with each other. The rotating drum 201 is centered on the driving shaft 107. Three storage bins 202 are evenly installed in the circumferential direction of the center, the bottom of the storage bin 202 is connected with a first connecting pipe 203, the bottom of the first connecting pipe 203 is connected with a movable pipe 204, the movable pipe 204 is specifically a hose, a push rod 205 is fixedly connected to the side of the bottom of the movable pipe 204 close to the driving shaft 107, a sliding rod 206 is fixedly connected to the side of the bottom of the movable pipe 204 away from the driving shaft 107, the sliding rod 206 passes through the rotating cylinder 201, a first elastic member 207 is arranged between the movable pipe 204 and the rotating cylinder 201, the first elastic member 207 is specifically a spring, the first elastic member 207 is coiled on the sliding rod 206, and the push rod 205 abuts against the side wall of the truncated cone block 108; It also includes a second motor 401 and a screw conveying paddle 402. The storage bin 202 is in the shape of a cone with a larger upper end and a smaller lower end. The second motor 401 is installed in the storage bin 202. The screw conveying paddle 402 is fixedly connected to the output shaft of the second motor 401. The bottom of the screw conveying paddle 402 extends into the first connecting pipe 203, but the screw conveying paddle 402 does not interfere with the operation of other components.

[0025] It can be seen that the ingredients with good proportions are first loaded into the storage bin 202, such as corn flour, wheat flour and meat powder, and then the second motor 401 is started, and the output shaft of the second motor 401 drives the screw conveying paddle 402 to rotate, and then the screw conveying paddle 402 conveys the ingredients to the first connecting pipe 203, and then the ingredients fall into the mixing drum 102 through the movable tube 204 by gravity, and at the same time the first motor 603 is started, and then the output shaft of the first motor 603 drives the gear 602 to rotate, and the gear 602 drives the ring gear 601 to rotate through meshing transmission, and then drives the storage bin 202 to rotate, so that various ingredients can fall into the mixing drum 102 evenly, ensuring the efficiency and uniformity of the subsequent mixing process, and preventing the accumulation of various ingredients before mixing, thereby causing the problem of long mixing time, and the third motor 106 is started, and the output shaft of the third motor 106 drives the drive shaft 107 to rotate, and then drives The shaft 107 drives the stirring assembly to stir the various ingredients, so that the ingredients can be mixed evenly. At the same time, due to the rotation of the driving shaft 107, the driving shaft 107 causes the truncated cone block 108 to move up and down reciprocatingly through the threaded connection. When the truncated cone block 108 moves downward, the inclined surface of the truncated cone block 108 squeezes the ejector rod 205, and then squeezes the lower end of the movable tube 204, and then the movable tube 204 squeezes the first elastic member 207, so that the first elastic member 207 is squeezed and deformed, and then the first elastic member 207 stores elastic potential energy. When the truncated cone block 108 moves upward, the first elastic member 207 releases the elastic potential energy, so that the lower end of the movable tube 204 is reset. In this way, when the truncated cone block 108 moves up and down reciprocatingly, the lower end of the movable tube 204 swings back and forth, thereby expanding the range of material dropping, making the various ingredients distributed more evenly, further reducing the mixing time, improving the mixing quality, and preventing the ingredients from being blocked or accumulated in the movable tube 204.

[0026] For further information, see Figure 1 , Figure 3 and Figure 4, further comprising a fixing box 301, a fixing rod 302, a stopper 303, a magnetic member 304, an electromagnet 305, a second elastic member 306 and a battery 109, the outer wall of the first connecting tube 203 is connected with the fixing box 301, the fixing rods 302 are fixedly connected to both sides of the fixing box 301, the fixing rods 302 are slidably connected with the magnetic member 304, the magnetic member 304 is specifically a magnet, a second elastic member 306 is arranged between the magnetic member 304 and the fixing box 301, the second elastic member 306 is specifically a spring, and the fixing box 301 is sealed and slidably connected with a stopper. 303, one end of the stopper 303 is fixedly connected to the magnetic member 304, an electromagnet 305 matching the magnetic member 304 is installed on the fixed box 301, the electromagnet 305 is energized and magnetically connected to the magnetic member 304, a battery 109 is arranged on the top surface of the rotating cylinder 201, the battery 109 is electrically connected to the second motor 401 and the electromagnet 305, so that when the second motor 401 and the electromagnet 305 are working, the wire can be prevented from being entangled. It can be seen that the electromagnet 305 is started, and then the electromagnet 305 and the magnetic member 304 attract each other, and then the electromagnet 305 The second elastic member 306 is magnetically connected to the magnetic member 304, and then the magnetic member 304 squeezes the second elastic member 306, so that the second elastic member 306 is compressed, and the second elastic member 306 stores elastic potential energy, and then the magnetic member 304 drives the stopper 303 to slide in the fixed box 301, and then the stopper 303 slides into the first connecting tube 203, separating the first connecting tube 203 from the movable tube 204, so that the storage bin 202 and the first connecting tube 203 are in a relatively closed space, and when it is necessary to drop the material, the electromagnet 305 is closed, and then the second elastic member 306 is released. The elastic potential energy is released, so that the magnetic part 304 is reset, and then the stopper 303 is reset, and then the first connecting tube 203 is connected with the movable tube 204. In this way, the order of the ingredients falling can be controlled. For example, corn flour and wheat flour are relatively dry ingredients, so these two powders can be mixed first. Meat powder generally contains higher fat and protein, and may be more viscous or have a higher density. Therefore, it is usually added after the drier powders are mixed. In this way, a gradual addition method is adopted, and each ingredient is added in batches and stirred continuously to ensure that each raw material can be evenly mixed.

[0027] For further information, see Figure 2 , Figure 3 and Figure 5The spray assembly includes a piston cylinder 501, a water inlet pipe 502, a second connecting pipe 503, a spray head 504, a sealing plug 505 and a piston rod 506. The piston cylinder 501 is evenly installed in the box body 105 with the truncated cone block 108 as the center. The sealing plug 505 is sealed in the piston cylinder 501. The bottom surface of the sealing plug 505 is fixedly connected to the piston rod 506. The lower end of the piston rod 506 penetrates the box body 105 and is fixedly connected to the truncated cone block 108. Therefore, when the truncated cone block 108 moves up and down, it moves up and down with the piston rod 506 as the guide. The bottom surface of the truncated cone block 108 is evenly installed with spray rods 506. The piston cylinder 501 is connected with a water inlet pipe 502 and a second connecting pipe 503, the second connecting pipe 503 is a hose, and a one-way valve is arranged on the water inlet pipe 502 and the second connecting pipe 503, and the second connecting pipe 503 is connected with the nozzle 504; the spray assembly also includes a water pump 511, a sealing box 512 and a joint 513, a joint 513 is installed on the top of the box body 105, a water pump 511 is installed in the box body 105, the water pump 511 is connected to the joint 513 through a pipeline, a sealing box 512 is fixed in the box body 105, and the third motor 106 is installed in the sealing box 512. The third motor 106 can be prevented from being disturbed; therefore, the connector 513 can be connected to a well-proportioned liquid from the outside, such as milk, and then the water pump 511 can be started. The water pump 511 extracts the well-proportioned liquid from the outside and passes it into the box body 105. Due to the up and down movement of the truncated cone 108, the sealing plug 505 is driven to move up and down, so that the piston cylinder 501 extracts liquid from the box body 105 through the water inlet pipe 502, and then the liquid is transported from the second connecting pipe 503 to the nozzle 504, and sprayed out by the nozzle 504. In this way, the liquid can be continuously injected while the ingredients are being fed and stirred. It can effectively avoid excessive stratification or uneven mixing of liquid and other ingredients, and avoid excessive wetness or dryness in some areas, which helps to improve the final taste and quality and enhance the flavor of pet food. It should be noted that the water pump 511 can be started at a certain moment of stirring, so that the nozzle 504 can spray a fixed amount of liquid at a specific time, and the nozzle 504 sprays air at other times. The water pump 511 can also continuously extract liquid, so that the nozzle 504 sprays liquid until the stirring is completed, and the amount sprayed just meets the requirements of ingredient mixing. The above two methods will not affect the mixing of pet food.

[0028] For further information, see Figure 2 , Figure 6 , Figure 7 and Figure 8The stirring assembly includes a stirring rod 701, a spiral blade 702, a universal ball 704, a stirring block 703, a connecting block 705, a torsion spring 706 and a reinforcing plate 707. Four stirring rods 701 are arranged on the driving shaft 107. The stirring rods 701 are spirally distributed along the surface of the driving shaft 107. A spiral blade 702 is arranged between the stirring rod 701 and the driving shaft 107. Three stirring blocks 703 are arranged axially on the stirring rod 701. A limiting groove 7031 is arranged on the stirring rod 701. A universal ball 704 is movably connected in the limiting groove 7031. A connecting block 705 is fixedly connected to one end of the universal ball 704. The connecting block 705 is rotatably connected to the stirring block 703. A torsion spring 706 is arranged between the connecting block 705 and the stirring block 703.

[0029] The stirring block 703 is trapezoidal, and the end of the stirring block 703 close to the stirring rod 701 is smaller than the end of the stirring block 703 away from the stirring rod 701. The stirring block 703 is an elastic member, specifically a rubber block. The inclined surface of the stirring block 703 is arranged up and down, and a reinforcing plate 707 is fixedly connected to the inclined surface of the stirring block 703. It can be seen that when the driving shaft 107 rotates, the stirring effect is achieved through the cooperation of the stirring rod 701 and the spiral blade 702. While the stirring rod 701 is stirring, the feed ingredients will pass through the surface of the reinforcing plate 707 and then diffuse up and down to achieve the effect of turbulence. Since the density of different materials may be different, the density of different areas of the ingredients is different when they are not evenly stirred. Therefore, the stirring block 703 is shaken with the universal ball 704 as the center, so that the stirring block 703 will not stir according to a fixed trajectory, thereby improving the stirring effect. At the same time, since the stirring block 703 is an elastic member, the resistance of different areas is different. The ingredients will squeeze the reinforcing plate 707, so that the stirring block 70 3 is squeezed, and the angles of the upper and lower reinforcing plates 707 can be changed, thereby changing the turbulence angle. For example, when corn flour and wheat flour are mixed, the angle formed by the upper and lower reinforcing plates 707 is larger, thereby making the turbulence angle larger and promoting uniform mixing. After adding meat powder, the upper and lower reinforcing plates 707 are subjected to greater resistance, so the angle formed is also smaller, making the turbulence effect more refined, thereby effectively adapting to the mixing requirements of different materials. At the same time, the side of the stirring block 703 is a plane setting. When the resistances of the two plane sides in one area are different, the stirring block 703 will rotate with the connecting block 705 as the center, thereby making the torsion spring 706 store elastic potential energy. When moving to another area, the resistances of the two plane sides are different from those in the previous area, and then the torsion spring 706 releases the elastic potential energy, so that the stirring block 703 rotates, thereby making the mixing process more efficient, and the ingredients can be mixed faster and more evenly, thereby improving the overall production efficiency.

[0030] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
