[0026] The following further illustrates the present utility model in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and can implement it, but the embodiments cited do not limit the present utility model.

[0027] Refer to Figures 1 to 5As shown in the figure, a bottom valve of a material suction hopper of the present utility model includes a mixing tank 1. One side of the mixing tank 1 is fixedly installed with a feed pipe 2. One end of the feed pipe 2 is fixedly connected with a feed inlet 21. The outer surface of the feed inlet 21 is fixedly installed with a tipping cylinder 3. The top of the mixing tank 1 is fixedly installed with an exhaust fan 5;

[0028] It further includes a control structure for controlling the material suction speed;

[0029] The control mechanism includes a flow limiting ring 4. The flow limiting ring 4 is fixedly installed on the inner wall of the mixing tank 1. Two rotating shafts 41 are rotatably installed on the inner surface of the flow limiting ring 4. A baffle 42 is fixedly installed on the outer surface of the rotating shaft 41. A groove 43 is opened on the top of the baffle 42. A slider 44 is slidably installed on the inner surface of the groove 43. A connecting rod 45 is fixedly installed on the tops of the two sliders 44. One side of the connecting rod 45 is fixedly connected with a second electric telescopic rod 46.

[0030] When feeding breeding animals, it is necessary to mix a variety of materials and then send them to the animal's mouth. Since the mixing tank is relatively large in volume, it is necessary to suck the materials from a low place into the mixing tank.

[0031] When the present utility model is in use, first pour the materials to be mixed into the tipping cylinder 3 and make the materials cover the feed inlet 21. Then start the exhaust fan 5 to make the inner cavity of the mixing tank 1 in a negative pressure state. At this time, the materials will enter the mixing tank 1 through the feed inlet 21. During the process of entering the mixing tank 1, the materials will pass through the flow limiting ring 4. In order to enable the materials to quickly enter the mixing tank 1, at this time, the second electric telescopic rod 46 extends to push the connecting rod 45. The connecting rod 45 drives the two sliders 44 to move. The two sliders 44 slide on the inner surfaces of the two grooves 43 respectively. At this time, the two sliders 44 control the opening angle of the two baffles 42, thereby controlling the feeding rate.

[0032] Furthermore, as Figure 1 shown, four support legs 11 are fixedly installed at the bottom of the mixing tank 1. The four support legs 11 are divided into two groups in pairs. A discharge opening 13 is opened at the bottom of the mixing tank 1. A discharge pipe 12 is fixedly connected to the bottom of the discharge opening 13. A first valve 121 is fixedly connected to the outer surface of the discharge pipe 12.

[0033] Since materials need to be stored in the mixing tank 1 for a long time, it is necessary to keep the mixing tank 1 away from the ground to prevent the materials from getting damp. Supporting the mixing tank 1 by the four support legs 11 is also beneficial to keep the mixing tank 1 stable. When it is necessary to draw out the materials in the mixing tank 1, by opening the first valve 121, the materials in the mixing tank 1 will flow out through the discharge pipe 12.

[0034] Furthermore, as Figure 2 and Figure 3As shown, a first motor 31 is fixedly installed at the bottom of the inner surface of the discharging cylinder 3. The output shaft of the first motor 31 is fixedly connected to a first pulley 32, and a belt 33 is wound around the outer surface of the first pulley 32.

[0035] The belt 33 is wound around the inner surface of a second pulley 34. Two flow disturbing blocks 37 are fixedly installed on the outer surface of the second pulley 34. Limiting rings 35 are rotatably installed at the top and bottom of the second pulley 34. The two limiting rings 35 are fixedly connected to a fixing block 36, and the fixing block 36 is fixedly installed at the bottom of the feeding port 21.

[0036] A bottom plate 302 is slidably installed on the inner surface of the discharging cylinder 3. Three first electric telescopic rods 301 are fixedly installed on the top of the bottom plate 302, and the three first electric telescopic rods 301 are fixedly installed on the top wall of the inner surface of the discharging cylinder 3.

[0037] When the present utility model conveys materials into the mixing tank 1, first, the first motor 31 drives the first pulley 32 to rotate. Through the transmission of the belt 33, the second pulley 34 also rotates. When the second pulley 34 rotates, the two flow disturbing blocks 37 also rotate with the second pulley 34. Since the materials are relatively dry, it is easy for the materials to be blocked at the feeding port 21. During material conveyance, the rotating flow disturbing blocks 37 can crush the agglomerated materials, avoiding the blockage of the agglomerated materials in the feeding pipe 2. At the same time, through the stirring of the flow disturbing blocks 37, the materials can enter the feeding pipe 2 more evenly, and the materials can be quickly conveyed when it is necessary to quickly convey the materials into the mixing tank 1.

[0038] During the process of conveying materials into the mixing tank 1, the materials in the discharging cylinder 3 will gradually decrease. Since the feeding port 21 cannot suck materials when the materials are far from the feeding port 21, during suction, the first electric telescopic rod 301 contracts to drive the bottom plate 302 to move upward, moving the materials as a whole. At this time, it can be ensured that the feeding port 21 can always suck materials.

[0039] Further, as Figure 4 and Figure 5 shown, one end of the feeding pipe 2 penetrates into the inner cavity of the mixing tank 1. The flow limiting ring 4 is fixedly connected to the feeding pipe 2 penetrating into the inner cavity of the mixing tank 1. One end of the second electric telescopic rod 46 is fixedly connected to a connecting block 47, and the connecting block 47 is fixedly installed on the top of the flow limiting ring 4. The two baffle plates 42 can seal one side of the flow limiting ring 4.

[0040] An air blowing pipe 61 is fixedly connected to the outer surface of the feeding pipe 2. A second valve 62 is fixedly connected to the outer surface of the air blowing pipe 61. The suction port of the air extractor 5 penetrates into the inner cavity of the mixing tank 1.

[0041] A second motor 71 is fixedly connected to the bottom of the stirring tank 1. The output shaft of the second motor 71 penetrates into the inner cavity of the stirring tank 1 and is fixedly connected to a stirring shaft 72. Stirring rods 73 are fixedly connected to the outer surface of the stirring shaft 72.

[0042] When the present utility model is in use, when the stirring tank 1 is filled with materials, the feeding needs to be stopped. At this time, the exhaust fan 5 stops. However, there will still be some materials remaining in the feeding pipe 2 at this time. It is necessary to remove the materials in the feeding pipe 2 to prevent the materials from deteriorating in the feeding pipe 2. At this time, the hair dryer 6 is turned on to blow air into the feeding pipe 2. Before blowing, the two baffles 42 approach each other and close tightly. At this time, the air blown out by the air blowing pipe 61 can only flow out through the feeding port 21. During the process of the air flowing out, the materials in the feeding pipe 2 will also flow into the tipping cylinder 3 along with the air flow. When feeding materials into the stirring tank 1, the second valve 62 closes tightly, which can prevent air leakage and also prevent materials from entering the air blowing pipe 61.

[0043] When the materials enter the stirring tank 1 and during the process of discharging the materials, the output shaft of the second motor 71 drives the stirring shaft 72 to rotate, and the stirring shaft 72 drives the stirring rods 73 to rotate. The stirring rods 73 can stir the materials in the stirring tank 1, which is beneficial to making the materials in the stirring tank 1 mix more evenly and also helps to quickly discharge the materials.

[0044] Working principle: First, pour the materials into the tipping cylinder 3, and then start the exhaust fan 5. Since the materials in the tipping cylinder 3 block the feeding port 21, the inside of the stirring tank 1 can be evacuated to a negative pressure through the exhaust fan 5. During this process, the materials will enter the stirring tank 1 through the feeding port 21 and the feeding pipe 2. When it is necessary to control the material flow rate, the second electric telescopic rod 46 extends or contracts to make the slider 44 slide on the inner surface of the groove 43, which can change the angle of the two baffles 42, so as to achieve the purpose of controlling the rate of the materials entering the stirring tank 1.

[0045] After all the materials have completely entered the stirring tank 1, there will still be some materials remaining in the feeding pipe 2. By blowing air into the air blowing pipe 61 with the hair dryer 6 and then blowing it towards the feeding port 21, the remaining materials in the feeding pipe 2 can be blown into the tipping cylinder 3, which is convenient for the staff to clean the remaining materials. During the process of extracting the materials from the stirring tank 1, the output shaft of the second motor 71 drives the stirring shaft 72 to rotate, and the stirring shaft 72 drives the two stirring rods 73 to rotate. The rotation of the stirring rods 73 can stir the materials, which helps the materials to be discharged from the discharging pipe 12.

[0046] Obviously, the above embodiments are only examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom still fall within the protection scope of the creation of the present utility model.
