Abstract
Description
Technical Field
[0001] This utility model relates to the field of feed production technology, and in particular to a feed mixing device. Background Technology
[0002] Mixing is a crucial step in chicken feed production. Currently, the main raw materials for chicken feed include grains (such as corn, wheat, sorghum, etc.), proteins (such as soybean meal, fish meal, meat and bone meal, etc.), minerals (such as calcium carbonate, dicalcium phosphate, etc.), vitamins and additives, and green fodder (such as alfalfa meal, vegetable scraps, etc.).
[0003] Existing chicken feed mixing devices have the following problems when processing these raw materials:
[0004] Firstly, most current mixing devices use a single mixing shaft with simple blades. When corn kernels with large density differences are mixed with calcium carbonate powder, it is difficult to achieve uniform dispersion through simple mixing. This often results in a layering phenomenon where the mineral powder sinks to the bottom and the grain kernels float on the top, leading to uneven distribution of nutrients.
[0005] Secondly, the feed ingredients contain oily fishmeal and damp green fodder, which makes the feed sticky and easy to adhere to the inner wall of the mixing tank, resulting in incomplete discharge and increasing the difficulty of cleaning.
[0006] Therefore, it is extremely important to provide a mixing device that can effectively improve mixing efficiency and reduce material residue. Utility Model Content
[0007] The purpose of this invention is to provide a feed mixing device to improve mixing efficiency, reduce material residue, and reduce the difficulty of cleaning the mixing tank.
[0008] The objective of this utility model is achieved through the following technical solution:
[0009] A feed mixing device includes a support frame, a mixing tank, and a mixing assembly; the support frame is used to support the mixing tank.
[0010] The mixing tank is horizontally mounted on the support frame and is cylindrical. The top of the mixing tank has a feed inlet and the bottom of the mixing tank has a discharge outlet.
[0011] The stirring assembly includes a rotating shaft coaxially and rotatably disposed within the stirring tank, multiple stirring shafts disposed on the outer wall of the rotating shaft, at least one scraper slidably disposed on the inner wall of the stirring tank and connected to the stirring shaft, and a motor disposed on the outer wall of the stirring tank and fixedly connected to one end of the rotating shaft.
[0012] Preferably, an arc-shaped baffle is movably provided at the discharge port.
[0013] Preferably, the feed mixing device further includes a drive assembly disposed on the support frame and used to drive the arc-shaped baffle to perform vertical and horizontal displacement.
[0014] Preferably, the support frame includes two limiting sleeves sleeved on the outside of the mixing tank, a support seat disposed at the bottom end of each limiting sleeve, and multiple reinforcing ribs disposed between the two limiting sleeves; the drive assembly includes an L-shaped plate disposed on the reinforcing ribs, a first hydraulic rod disposed on the side wall of the L-shaped plate, a first connecting block disposed at the telescopic end of the first hydraulic rod, and a second hydraulic rod disposed at the top end of the first connecting block; the telescopic end of the second hydraulic rod is fixedly connected to the arc-shaped baffle.
[0015] Preferably, a multi-stage telescopic plate is provided on the side wall of the L-shaped plate and below the first hydraulic rod, and the telescopic end of the first connecting block and the multi-stage telescopic plate are fixedly connected.
[0016] Preferably, the length of the discharge port is equal to the distance between the two ends of the mixing tank.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] 1. The horizontally positioned cylindrical mixing tank, coupled with a coaxial rotating shaft and multiple mixing shafts, enables the mixing of feed ingredients from multiple directions, effectively improving mixing uniformity. Scrapers sliding along the inner wall of the mixing tank are connected to the mixing shafts. Driven by the shafts, the scrapers move closely against the inner wall of the mixing tank, promptly scraping up settled mineral powders and other materials, quickly mixing them with other ingredients, effectively overcoming material stratification and improving the uniformity of nutrient distribution. Simultaneously, the scrapers also promptly remove sticky feed adhering to the tank wall (such as oily fishmeal or damp green fodder), preventing material adhesion and improving mixing uniformity. Finally, during discharge, scraping off any adhering material ensures complete discharge and significantly reduces the difficulty of cleaning the mixing tank.
[0019] 2. By flexibly setting an arc-shaped baffle at the discharge port, and in conjunction with a drive component for driving its vertical and horizontal displacement, the opening and closing of the discharge port can be flexibly controlled, improving the ease of operation.

Detailed Implementation
[0024] Example 1
[0025] A feed mixing device, such as Figures 1-3 As shown, it includes a support frame, a mixing tank 1, and a mixing assembly; the support frame supports the mixing tank 1; the mixing tank 1 is horizontally mounted on the support frame and is cylindrical, with a feed inlet at the top and a discharge outlet 2 at the bottom; as shown... Figure 1-3 As shown, the stirring assembly includes a rotating shaft 3 coaxially and rotatably disposed within the stirring tank 1, multiple stirring shafts 4 disposed on the outer wall of the rotating shaft 3, at least one scraper 5 slidably disposed on the inner wall of the stirring tank 1 and connected to the stirring shafts 4, and a motor 6 disposed on the outer wall of the stirring tank 1 and fixedly connected to one end of the rotating shaft 3. Further, as... Figure 1 As shown, the length of the discharge port is equal to the distance between the two ends of the mixing tank 1. Further, as... Figure 3 As shown, an arc-shaped baffle 7 is movably installed at the discharge port. In actual implementation, a baffle adapted to the shape of the inlet 2 is also installed at the inlet 2, and the baffle is fixed at the inlet by a fixing component, such as a buckle. The baffle and the buckle are both existing technologies and are not shown in the figure.
[0026] Working principle: Feed ingredients are added into the mixing tank 1 through the feed inlet, and then the baffle at the feed inlet is closed. Next, the motor 6 is started, driving the rotating shaft 3 to rotate coaxially within the mixing tank 1. Multiple stirring shafts 4 on the outer wall of the rotating shaft 3 rotate accordingly, stirring the feed ingredients within the mixing tank 1 from multiple directions. During the stirring process, due to the rotation of the stirring shafts 4, the scrapers 5 connected to the stirring shafts 4 slide against the inner wall of the mixing tank 1, scraping off feed adhering to the tank wall and lifting mineral powders settled at the bottom of the mixing tank 1, ensuring that all ingredients participate in the stirring and achieve thorough mixing. After the feed is stirred, the arc-shaped baffle 7 is removed from the discharge port 2 to collect the material.
[0027] Example 2
[0028] In Example 1, the placement and removal of the arc-shaped baffle 7 requires manual operation, which is inconvenient in actual implementation. Therefore, based on Example 1, the feed mixing device further includes a driving assembly mounted on the support frame for driving the arc-shaped baffle 7 to perform vertical and horizontal displacement. Further, the support frame includes two limiting sleeves 8 sleeved on the outside of the mixing tank 1, a support base 9 at the bottom of each limiting sleeve 8, and multiple reinforcing ribs 10 between the two limiting sleeves 8. The driving assembly includes an L-shaped plate 11 mounted on the reinforcing ribs 10, a first hydraulic rod 12 mounted on the side wall of the L-shaped plate 11, a first connecting block 13 at the telescopic end of the first hydraulic rod 12, and a second hydraulic rod 14 at the top of the first connecting block 13. The telescopic end of the second hydraulic rod 14 is fixedly connected to the arc-shaped baffle 7.
[0029] Working principle: After the feed is mixed, the movement of the arc-shaped baffle 7 is controlled by the drive component. Specifically, the second hydraulic rod 14 is first retracted. During retraction, the arc-shaped baffle 7 gradually disengages from the discharge port 2 until it moves to the bottom of the discharge port 2, as shown below. Figure 1-3 As shown, the first hydraulic rod 12 then retracts, causing the first connecting block 13 to move laterally, which in turn causes the second hydraulic rod 14 and the arc-shaped baffle 7 to move laterally, so that the arc-shaped baffle 7 gradually moves away from the discharge port. During this process, the feed is discharged from the discharge port.
[0030] Furthermore, throughout the entire working process, the limiting sleeve 8, support seat 9, and reinforcing rib 10 of the support frame work together to provide stable support for the mixing tank 1.
[0031] Example 3
[0032] In Embodiment 2, the first hydraulic rod 12 needs to bear the weight of the second hydraulic rod 14, the first connecting block 13, and the arc-shaped baffle 7. Prolonged operation leads to functional impairment of the first hydraulic rod 12. Therefore, based on Embodiment 2, a multi-stage telescopic plate 15 is provided on the side wall of the L-shaped plate 11, located below the first hydraulic rod 12. The telescopic ends of the first connecting block 13 and the multi-stage telescopic plate 15 are fixedly connected. By providing the multi-stage telescopic plate 15, it can extend and retract along with the first hydraulic rod 12, supporting the second hydraulic rod 14, the arc-shaped baffle 7, and the first connecting block 13, thereby sharing the load on the first hydraulic rod 12 and extending its service life.
[0033] like Figure 3As shown, the multi-stage telescopic plate 15 in this invention consists of two stacked displacement plates, with adjacent displacement plates slidably connected to ensure smooth extension and retraction of the multi-stage telescopic plate 15. In actual implementation, a slider can be provided on one side of the two adjacent displacement plates that are close to each other, and a horizontal groove (both the slider and the horizontal groove are existing technologies and are not shown in the figure) can be provided on the other side to ensure smooth extension and retraction of the multi-stage telescopic plate 15, while also ensuring that the multiple displacement plates do not completely separate.
