Description

Technical Field

[0001] This utility model relates to the technical field of feed mixing, and in particular to a mixing device for nutritional feed specifically for pregnant sows. Background Technology

[0002] Specialized nutritional feed for pregnant sows requires the mixing of various raw materials and nutrients. Existing technologies disclose various feed mixing devices. For example, Chinese utility model patent CN218047688U discloses a feed mixer. This feed mixer includes a base with support legs connected to the four corners of the base. A mixing chamber is connected to the top of the base. The top of the mixing chamber is a protruding cone shape, and multiple teeth are connected to the bottom of the cone on the inner circumference of the mixing chamber. A rotating disc is provided on the upper half of the inner circumference of the mixing chamber, and multiple feed inlets are opened on the top of the mixing chamber. A top plate is provided above the mixing chamber, and multiple feed pipes are installed on the top of the top plate. Electromagnetic valves are installed inside the feed pipes, and the bottom ends of the feed pipes are connected to the corresponding feed inlets on the top of the mixing chamber. This feed mixer can achieve uniform feeding, reducing the difficulty of mixing. Furthermore, the reciprocating cutting of the stirring rod and the rotation of the mixing rod can further improve the mixing efficiency.

[0003] However, when the above-mentioned mixer is working, its stirring component mixes all the materials in the mixing chamber at the same time. The stirring component is subject to greater resistance, which leads to a decrease in reliability. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a special nutrient feed mixing device for pregnant sows that uses an up-and-down circulation method to mix feed in batches and store feed in large quantities to improve reliability.

[0005] This utility model discloses a special nutrient feed mixing device for pregnant sows, comprising support legs, a mixing tank, and a feeding pipe. The mixing tank is mounted on the support legs and has a mixing chamber inside. A feeding pipe communicating with the mixing chamber is installed at the center of the top of the mixing tank. It also includes a screw conveyor, a distribution hopper, a storage tank, and a discharge pipe. The screw conveyor is installed in the middle of the mixing chamber of the mixing tank. The lower end of the screw conveyor has a feed inlet located at the bottom center of the mixing chamber, and the upper end of the screw conveyor has a discharge outlet located at the top center of the mixing chamber. The distribution hopper is vertically mounted on the upper outer wall of the screw conveyor. The storage tank is mounted on the outer wall of the screw conveyor. A material drop channel is provided between the side wall of the storage tank and the inner side wall of the mixing tank. A mixing space is provided between the bottom wall of the storage tank and the inner bottom wall of the mixing tank. A storage chamber is provided between the storage tank and the screw conveyor. An opening is provided at the top of the storage tank, located below and inside the distribution hopper. The inlet of the discharge pipe is connected to the storage chamber of the storage tank, and the outlet of the discharge pipe extends out of the bottom of the mixing tank. During operation, the distribution hopper descends to below the discharge port of the screw conveyor, allowing raw materials and nutrients to pass through. Nutrients are added to the top of the mixing chamber of the mixing tank through the feeding pipe and fall onto the distribution hopper. The distribution hopper disperses and guides the raw materials and nutrients into the discharge channel between the storage tank and the mixing tank. This process is the first mixing step. The raw materials and nutrients then flow into the mixing space through the discharge channel and gather again. This process is the second mixing step. The screw conveyor operates, lifting the raw materials and nutrients in the mixing space through the inlet and discharging them through the outlet, allowing the raw materials and nutrients to return to the distribution hopper for cyclic mixing. The feeding pipe continues to feed until a certain weight is reached and then stops. After the batch of raw materials and nutrients are mixed evenly, the feed hopper rises above the discharge port of the screw conveyor, causing the feed output by the screw conveyor to fall into the storage chamber between the screw conveyor and the storage tank for storage. After the feeding pipe feeds a certain weight again, it stops. The above operation is repeated to complete the mixing of multiple batches of feed and store the feed in the storage chamber. When it is necessary to discharge, the valve of the discharge pipe is opened to discharge the feed. Compared with the existing technology, it can mix feed in batches and store a large amount of feed. The upper and lower circulation method of mixing feed reduces the resistance of the mixing components and improves reliability.

[0006] Preferably, it also includes a spiral guide plate, which is spirally installed in the discharge channel between the storage tank and the mixing tank; the feed spirally descends along the spiral guide plate in the discharge channel between the storage tank and the mixing tank, which prolongs the feed flow path and allows the feed to be remixed during the spiral descent, thereby improving the mixing efficiency.

[0007] Preferably, the feed also includes multiple push rods, with the fixed ends of the push rods mounted on the storage tank. The piston rods of the push rods are connected to the feed hopper. When the piston rods of the push rods extend, they push the feed hopper upward, raising it above the discharge port of the screw conveyor. When the piston rods of the push rods retract, they pull the feed hopper downward, lowering it below the discharge port of the screw conveyor, thus adjusting the position of the feed hopper and changing the flow direction of the feed.

[0008] Preferably, it also includes a protrusion, an upper shaft, a hammer rod, a spring, and a hammer head. The protrusion is installed on the inner wall of the mixing tank. The end of the upper shaft is connected to the rotating shaft of the spiral blades inside the screw conveyor. The inner end of the hammer rod is connected to the upper shaft, and a spring is installed on the outer end of the hammer rod. The hammer head is installed on the end of the spring, and the hammer head collides with the protrusion. When the screw conveyor is running, its internal rotating shaft drives the spiral blades to rotate, which in turn drives the upper shaft to rotate. The upper shaft drives the hammer head to rotate through the hammer rod and the spring, causing the hammer head to intermittently strike the protrusion, thereby vibrating the mixing tank and preventing the feed from becoming blocked when flowing on the spiral guide plate.

[0009] Preferably, the device also includes a sampling window, a door panel, inner side panels, and a baffle. The sampling window is installed on the outer wall of the mixing tank and is connected to the material discharge channel between the storage tank and the mixing tank. The lower end of the door panel is hinged to the lower edge of the sampling window, and the door panel closes the outer port of the sampling window. Two inner side panels are installed opposite each other on the inner wall of the door panel, and a baffle is installed between the two inner side panels. The door panel, the two inner side panels, and the baffle constitute a hopper. During operation, the door panel closes the outer port of the sampling window. At this time, the two inner side panels and the baffle extend into the material discharge channel between the storage tank and the mixing tank, so that the falling feed enters the hopper formed by the door panel, the two inner side panels, and the baffle. The door panel is flipped outward to open, and the feed sample in the hopper is taken out to test the uniformity of the feed mixing.

[0010] Preferably, the device also includes a hinge shaft, a push rod, and a connecting rod. The hinge shaft is installed at the upper end of the baffle, and both ends of the hinge shaft are rotatably connected to the two inner side plates. The middle part of the push rod is slidably inserted into the door panel, and the inner end of the push rod is rotatably connected to the outer end of the connecting rod. The inner end of the connecting rod is rotatably connected to the baffle, and the outer end of the push rod extends outward from the door panel. When it is necessary to add medicine to the feed, the door panel is flipped outward to open, and the tablets are put into the hopper formed by the door panel, the two inner side plates, and the baffle. The door panel is flipped inward to close the outer port of the sampling window. The push rod is pushed inward, and the push rod pushes the baffle inward through the connecting rod, so that the lower end of the baffle rotates and opens around the hinge shaft, allowing the medicine in the hopper to enter the discharge channel between the storage tank and the mixing tank through the bottom of the baffle, thereby realizing temporary medicine addition.

[0011] Preferably, it also includes a weighing device, which is installed at the bottom of the outriggers; the weighing device weighs the feed to ensure accurate feeding for each batch.

[0012] Compared with the prior art, the advantages of this utility model are: it can mix feed in batches and store feed in large quantities. It uses an up-and-down circulation method to mix feed, resulting in less resistance to the mixing components and improved reliability. Attached Figure Description

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0021] Example 1

[0022] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, a special nutrient feed mixing device for pregnant sows includes a support leg 1, a mixing tank 2, and a feeding pipe 3. The mixing tank 2 is mounted on the support leg 1, and a mixing chamber is provided inside the mixing tank 2. The feeding pipe 3, which communicates with the mixing chamber, is installed at the center of the top of the mixing tank 2. It also includes a screw conveyor 4, a distribution hopper 5, a storage tank 6, and a discharge pipe 7. The screw conveyor 4 is installed in the middle of the mixing chamber of the mixing tank 2. An inlet is located at the bottom center of the mixing chamber of the mixing tank 2 at the lower end of the screw conveyor 4. An outlet is located at the top center of the mixing chamber of the mixing tank 2 at the upper end of the screw conveyor 4. The distribution hopper 5 is vertically mounted on the upper outer wall of the screw conveyor 4, and the storage tank 6 is mounted on the outer wall of the screw conveyor 4. A material discharge channel is provided between the side wall of the storage tank 6 and the inner side wall of the mixing tank 2. A mixing space is provided between the bottom wall of the storage tank 6 and the inner bottom wall of the mixing tank 2. A storage chamber is provided between the storage tank 6 and the screw conveyor 4. An opening is provided at the top of the storage tank 6, located below and inside the distribution hopper 5. The input end of the discharge pipe 7 is connected to the storage chamber of the storage tank 6, and the output end of the discharge pipe 7 extends out of the bottom of the mixing tank 2. The system also includes a screw guide plate 8, which is screwed in the material discharge channel between the storage tank 6 and the mixing tank 2. It also includes multiple push rods 9, the fixed ends of which are installed on the storage tank 6, and the piston rods of which are connected to the distribution hopper 5. Finally, it includes a weighing device 22, which is installed at the bottom of the support leg 1.

[0023] During operation, the piston rods of multiple push rods 9 retract, pulling the distribution hopper 5 downwards until it descends below the discharge port of the screw conveyor 4. Raw materials and nutrients are added through the feeding pipe 3 to the top of the mixing chamber of the mixing tank 2 and fall onto the distribution hopper 5. The distribution hopper 5 disperses and guides the raw materials and nutrients into the discharge channel between the storage tank 6 and the mixing tank 2; this is the first mixing stage. The raw materials and nutrients then enter the discharge channel and spiral down along the spiral guide plate 8, flowing into the mixing space to gather again; this is the second mixing stage. The screw conveyor 4 operates, drawing the raw materials and nutrients from the mixing space through the inlet into the screw conveyor 4, lifting them upwards, and discharging them through the outlet, allowing the raw materials and nutrients to return to the distribution hopper 5 for cyclic mixing. Feeding pipe 3 continues to feed until a certain weight is reached, then stops. Weighing device 22 weighs the feed. Once the batch of raw materials and nutrients are evenly mixed, the piston rods of multiple push rods 9 extend, pushing the distribution hopper 5 upwards. This raises the distribution hopper 5 above the discharge port of screw conveyor 4, causing the feed output from screw conveyor 4 to fall into the storage chamber between screw conveyor 4 and storage tank 6. Feeding pipe 3 feeds again until a certain weight is reached, then stops. The above operation is repeated to complete the mixing of multiple batches of feed and store the feed in the storage chamber. When discharge is needed, the valve of discharge pipe 7 is opened to discharge the feed. Compared with existing technologies, this method can mix feed in batches and store large quantities of feed. The use of an up-and-down circulation method for mixing feed reduces the resistance experienced by the mixing components, improving reliability.

[0024] The feed spirals down along the spiral guide plate 8 in the feed drop channel between the storage tank 6 and the mixing tank 2, which extends the feed flow path and allows the feed to be mixed again during the spiral descent, thus improving the mixing efficiency.

[0025] Example 2

[0026] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, based on Embodiment 1, it also includes a protrusion 10, an upper shaft 11, a hammer rod 12, a spring 13, and a hammer head 14. The protrusion 10 is installed on the inner wall of the mixing tank 2. The end of the upper shaft 11 is connected to the rotating shaft of the spiral blade inside the screw conveyor 4. The inner end of the hammer rod 12 is connected to the upper shaft 11. The outer end of the hammer rod 12 is equipped with a spring 13. The hammer head 14 is installed on the end of the spring 13 and the hammer head 14 collides with the protrusion 10.

[0027] When the screw conveyor 4 is running, its internal rotating shaft drives the screw blades to rotate, and the rotating shaft drives the upper shaft 11 to rotate. The upper shaft 11 drives the hammer head 14 to rotate through the hammer rod 12 and the spring 13, so that the hammer head 14 intermittently hits the protrusion 10, thereby vibrating the mixing tank 2 and preventing the feed from getting blocked when it flows on the screw guide plate 8.

[0028] Example 3

[0029] like Figures 1 to 4 As shown, based on Embodiment 1, it further includes a sampling window 15, a door panel 16, inner side panels 17, and a baffle 18. The sampling window 15 is installed on the outer wall of the mixing tank 2 and is connected to the material discharge channel between the storage tank 6 and the mixing tank 2. The lower end of the door panel 16 is hinged to the lower edge of the sampling window 15, and the door panel 16 closes the outer port of the sampling window 15. Two inner side panels 17 are installed opposite each other on the inner wall of the door panel 16, and a baffle 18 is installed between the two inner side panels 17. The baffle 18, door panel 16, two inner side panels 17 and the baffle 18 constitute a hopper; it also includes a hinge shaft 19, a top rod 20 and a connecting rod 21. The hinge shaft 19 is installed at the upper end of the baffle 18. The two ends of the hinge shaft 19 are rotatably connected to the two inner side panels 17. The middle part of the top rod 20 is slidably inserted into the door panel 16. The inner end of the top rod 20 is rotatably connected to the outer end of the connecting rod 21. The inner end of the connecting rod 21 is rotatably connected to the baffle 18. The outer end of the top rod 20 extends out of the outside of the door panel 16.

[0030] During operation, the door panel 16 closes the outer port of the sampling window 15. At this time, the two inner side panels 17 and the baffle 18 extend into the material drop channel between the storage tank 6 and the mixing tank 2, allowing the falling feed to enter the hopper formed by the door panel 16, the two inner side panels 17, and the baffle 18. The door panel 16 is flipped outward to open, and the feed sample in the hopper is taken out to check the uniformity of the feed mixing. When it is necessary to add medicine to the feed, the door panel 16 is flipped outward to open, and the tablets are put into the hopper formed by the door panel 16, the two inner side panels 17, and the baffle 18. The door panel 16 is flipped inward to close the outer port of the sampling window 15. The push rod 20 is pushed inward, and the push rod 20 pushes the baffle 18 inward through the connecting rod 21, so that the lower end of the baffle 18 rotates and opens around the hinge shaft 19, allowing the medicine in the hopper to enter the material drop channel between the storage tank 6 and the mixing tank 2 through the bottom of the baffle 18, realizing temporary medicine addition.

[0031] like Figures 1 to 6As shown, this utility model discloses a special nutrient feed mixing device for pregnant sows. During operation, the distribution hopper 5 first descends below the outlet of the screw conveyor 4. Raw materials and nutrients are added to the top of the mixing chamber of the mixing tank 2 through the feeding pipe 3 and fall onto the distribution hopper 5. The distribution hopper 5 disperses and guides the raw materials and nutrients into the discharge channel between the storage tank 6 and the mixing tank 2. This process constitutes the first mixing. Afterwards, the raw materials and nutrients flow spirally through the screw guide plate 8 in the discharge channel for a second mixing. The feed flows into the mixing space and gathers again; this process constitutes the second mixing. Then, the screw conveyor 4 operates, feeding the raw materials and nutrients in the mixing space into the screw conveyor through the inlet. The feed is lifted upwards in the conveyor 4 and discharged through the outlet, allowing the raw materials and nutrients to return to the distribution hopper 5 for cyclic mixing. The feeding pipe 3 continues to feed until a certain weight is reached and then stops. The weighing device 22 weighs the feed to ensure accurate feeding for each batch. After the batch of raw materials and nutrients is evenly mixed, the distribution hopper 5 rises above the outlet of the screw conveyor 4, causing the feed output by the screw conveyor 4 to fall into the storage chamber between the screw conveyor 4 and the storage tank 6 for storage. The feeding pipe 3 feeds a certain weight again and then stops. The above operation is repeated to complete the mixing of multiple batches of feed and store the feed in the storage chamber. Finally, when it is time to discharge, the valve of the discharge pipe 7 is opened to discharge the feed.

[0032] The main functions achieved by this utility model are:

[0033] 1. It can mix feed in batches and store large quantities of feed. It uses an up-and-down circulation method to mix feed, which reduces the resistance of the mixing components and improves reliability.

[0034] 2. It can vibrate the mixing tank 2 to prevent the feed from getting clogged when it flows on the spiral guide plate 8;
