DETAILED DESCRIPTION

[0030] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0031] like Figure 1 As shown, an embodiment of the utility model proposes a feed additive quantitative feeding device, including a shell 1, the shell 1 is configured as a cylindrical structure, a motor 24 is arranged at the center of the top of the shell 1, and the motor shaft of the motor 24 is inserted into the shell 1, and a first feed port 11 and a second feed port 12 are symmetrically arranged on both sides of the motor 24 at the top of the shell 1, and the first feed port 11 and the second feed port 12 are configured as a funnel shape with a wide top and a narrow bottom, which is convenient for better adding feed and additives, and a conical inclined structure is arranged near the bottom of the shell 1, so that the feed can be more concentrated after mixing, which is convenient for discharging, and a support frame 13 is also fixedly arranged at the inclined structure of the shell 1 for stabilizing the device.

[0032] like Figure 2 and Figure 5 As shown, a stirring mechanism 2 is also provided inside the shell 1, and the stirring mechanism 2 includes a vertically fixed rotating shaft 21, and the top of the rotating shaft 21 is rotatably connected to the motor shaft of the motor 24, and a plurality of fan blades 22 are arranged around the rotating shaft 21, and the fan blades 22 are in a rectangular plate-like structure. In order to improve the stirring effect of the device, the fan blades 22 are provided with a plurality of hollow portions 221 penetrating the upper and lower end surfaces, and a gap is left between the end surface of the fan blade 22 away from the rotating shaft 21 and the inner wall of the shell 1 to prevent the feed from sticking to the inner wall and affecting the mixing effect, and the fan blades 22 and corresponding hollow portions 221 that fit the shape of the inner wall are also provided in the concentrated unloading area of ​​the inclined structure.

[0033] Combination Figure 3 and Figure 4As shown, the outer shell 1 is provided with a discharge port 14 at the bottom. According to another embodiment of the utility model, a plurality of strip-shaped scraper plates 23 are also provided on the rotating shaft 21. The scraper plates 23 are close to the bottom surface of the inner wall of the outer shell 1 to continuously push the bottom feed to stir and mix. When the feed is less, the material can be pushed into the discharge port 14. To ensure the pushing effect, the length of the scraper plates 23 is set to be consistent with the radius of the bottom surface of the inner wall of the outer shell 1.

[0034] like Figure 5 and Figure 6 As shown, the embodiment of the utility model proposes a feed additive quantitative feeding device, which is also provided with a quantitative mechanism 3, and the quantitative mechanism 3 includes a driving gear 31, and the driving gear 31 is rotatably connected to the bottom end of the rotating shaft 21. In order to facilitate the size adjustment of the driving gear 31, the bottom end part of the rotating shaft 21 is set as a small-diameter rotating shaft 211. The driving gear 31 is also rotatably engaged with a driven gear 32. In order to control the rotation speed of the quantitative mechanism 3, the diameter of the driving gear 31 is smaller than the diameter of the driven gear 32.

[0035] Combination Figure 7 As shown, the driven gear 32 is provided with a planar outer groove wheel mechanism, and the groove wheel mechanism includes a driving dial 33 and a driven groove wheel 34. The driving dial 33 is a disc structure, and the driving dial 33 is coaxially fixedly arranged on the upper end surface of the driven gear 32. The rotating end surface of the driving dial 33 is provided with a convex locking arc 333, and a section of the convex locking arc 333 is provided with an arc-shaped notch 332. A cylindrical pin 331 is provided on a side close to the arc-shaped notch 332. The upper end surface of the driving dial 33 is rotatably connected to the bottom of the housing 1 through a first fixed shaft 334. The driven groove wheel 34 is a square structure, and the four sides of the driven groove wheel 34 are provided with convex locking arcs 333 that are engaged with the driving dial 33. The four corners of the driven sheave 34 are provided with radial guide grooves 342 which are rotatably engaged with the cylindrical pin 331. When the cylindrical pin 331 rotates and enters the radial guide grooves 342, the driven sheave 34 is driven to rotate until the driven sheave 34 rotates 90 degrees from the original angle, and the cylindrical pin 331 moves out of the radial guide grooves 342. When the driven sheave 34 continues to rotate, the convex locking arc 333 of the active dial 33 locks the concave locking arc 341 of the driven sheave 34 to prevent it from moving, until the cylindrical pin 331 rotates one circle and enters the radial guide groove 342 again, driving the driven sheave 34 to rotate again, and repeats this process. The driven sheave 34 is fixed in position for a period of time every time it rotates 90 degrees.

[0036] like Figure 6As shown, the upper end surface of the driven groove wheel 34 is also fixed with a limiting disc 35, and the limiting disc 35 is rotatably connected to the bottom of the housing 1 through a second fixed shaft 343. The limiting disc 35 is provided with a discharge hole 351 that passes through the upper and lower end surfaces, and the discharge hole 351 is arranged near the middle section of the concave locking arc 341. Figure 8 and Fig. 9 As shown, when the discharge hole 351 overlaps with the discharge port 14 when the groove wheel mechanism is locked, the material can be discharged. According to another embodiment, multiple discharge ports 14 can be set according to actual production conditions to increase the discharge amount. According to another embodiment, in order to prevent the limiting disc 35 from loosening and deviating during the rotation and discharging process, which may cause leakage, a mounting groove 15 for the limiting disc 35 to be embedded is further provided at the bottom of the housing 1. The limiting disc 35 will rotate in the mounting groove 15 to increase the stability of the discharge.

[0037] The technical principle of the utility model is as follows: when feeding, feed and additives are put into the device from the first feed port 11 and the second feed port 12 in a certain proportion, the motor 24 is turned on to drive the rotating shaft 21 to rotate, and the fan blades 22 on the rotating shaft 21 stir and mix the feed and additives. The rotation of the rotating shaft 21 will also drive the driving gear 31 at the bottom to rotate, thereby driving the driven gear 32 and the active component on the driven gear 32 to rotate. Due to the particularity of the grooved wheel mechanism, the active component will drive the driven grooved wheel 34 and The limiting disc 35 on the driven groove wheel 34 makes intermittent motion. When the discharge hole 351 on the limiting disc 35 coincides with the discharge port 14, the feed in the device will be discharged. Since the groove wheel mechanism rotates at a uniform speed, the coincidence time of the discharge hole 351 and the discharge port 14 is fixed, so the discharge amount is also fixed. By adjusting the speed of the motor 24, the meshing ratio of the driven and driving gears 31, and the number of the discharge holes 351, the coincidence time of the discharge holes 351 and the discharge port 14 can be controlled, so that the quantitative control of the discharge can be completed.

[0038] Compared with the prior art, the utility model has the following beneficial effects: by setting up a stirring mechanism 2, the feed and the additive can be fully mixed, and by setting up a quantitative mechanism 3, the particularity of the groove wheel mechanism is utilized to control the time when the discharge hole 351 overlaps with the discharge port 14, thereby completing the quantitative control of the discharge. In this device, only one motor 24 can be used to realize the automatic quantitative operation of the entire device, and the discharge amount can be controlled by adjusting the speed of the motor 24, the meshing ratio of the driven and driving gears 31, and the number of the discharge holes 351. The operation is simple and convenient, and the practicality is high.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
