Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, and in particular to a feed mixer. Background Technology

[0002] Currently available feed mixers primarily use two parallel auxiliary augers and a main auger located below them to cut the feed. The two auxiliary augers and the main auger are connected by a sprocket and chain drive. A drive unit rotates the main auger, which in turn drives the two auxiliary augers to rotate synchronously. However, in existing feed mixers, the two auxiliary augers rotate in the same direction. This results in one auxiliary auger rotating towards the gap between the two auxiliary augers, while the other rotates away from the gap. Because the distance between the auxiliary augers and the inner wall of the feed mixer is small, feed may get stuck between the auxiliary auger rotating away from the gap and the inner wall of the feed mixer. This not only increases the load on the drive unit but also affects the feed cutting efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a feed mixer that can guide feed toward the main auger and improve cutting efficiency.

[0004] To achieve this objective, the present invention adopts the following technical solution: a feed mixer, comprising a body, a cutting mechanism, and a drive component, wherein the body is provided with a working chamber; the cutting mechanism includes two auxiliary augers and one main auger, both ends of the auxiliary augers and both ends of the main auger are rotatably connected to two opposite sidewalls of the working chamber, the two auxiliary augers are spaced apart along the width direction of the working chamber, the main auger is located below the auxiliary augers and between the two auxiliary augers, one end of the main auger extends out of the working chamber and is connected to a first sprocket, and one of the auxiliary augers... One end of the main auger extends out of the working chamber and is connected to a second sprocket. One end of the other auxiliary auger extends out of the working chamber and is connected to a first gear. The outer wall of the machine body is provided with a rotatable rotating rod. A third sprocket and a second gear are fixed on the rotating rod. The first sprocket, the second sprocket, and the third sprocket are connected by chain drive, and the first gear and the second gear mesh. The driving component is connected to the main auger to drive the main auger and the two auxiliary augers to rotate synchronously, and the two auxiliary augers are driven to rotate towards each other through the first gear and the second gear.

[0005] Preferably, both the main auger and the two auxiliary augers have helical cutting blades, the helical cutting blades of the two auxiliary augers rotate in opposite directions, and the helical cutting blades of the main auger rotate in the same direction as the helical cutting blades of the auxiliary auger connected to the first gear.

[0006] Preferably, the side wall of the machine body is fixed with a vertical support plate, and two bearing seats are spaced apart on the support plate. The two ends of the rotating rod are rotatably mounted on the two bearing seats, and the support plate has a hollow structure for the chain to pass through.

[0007] Preferably, the support plate has flanged portions on both sides, and a first nut is welded to the flanged portions. Two second nuts are spaced apart along the vertical direction on the side wall of the machine body. The second nuts and the first nuts correspond one-to-one and are bolted together.

[0008] Preferably, the cutting blade of the main auger is connected to a detachable blade assembly along its edge, the blade assembly protruding radially from the main auger.

[0009] Preferably, the blade assembly includes a main cutter, which has a curved triangular shape and serrated edges.

[0010] Preferably, the blade assembly further includes multiple pentagonal blades, which are spaced apart along the spiral direction of the cutting disc.

[0012] Preferably, the feed mixer further includes a control box located on one side of the drive unit and electrically connected to the drive unit.

[0013] The beneficial effects of this invention are as follows: When the feed mixer is working, the drive unit drives the main auger to rotate. The main auger drives the chain, second auger, and third auger to rotate via the first sprocket. The third sprocket drives the first gear to rotate via the rotating rod and second gear, thereby driving the two auxiliary augers to rotate in opposite directions. The two auxiliary augers rotating in opposite directions can guide the feed to fall quickly onto the main auger. The two auxiliary augers and the main auger work together to quickly cut the feed. By setting the first gear and the second gear, the two auxiliary augers can be driven to rotate in opposite directions, avoiding feed jamming, reducing the load on the drive unit and effectively improving the cutting efficiency of the feed mixer. It can also simplify the transmission structure between the auxiliary augers and the main auger, reducing the operating cost of the cutting mechanism. Attached Figure Description

[0026] Reference Figures 1 to 3 As shown, a feed mixer according to an embodiment of this application includes a body 100, a cutting mechanism 200, and a drive component 300. The body 100 has a working chamber 110, which is bucket-shaped with an opening at the top. The two side walls of the working chamber 110 are respectively provided with a feeding port and a discharging port. Since the structure of the body 100 is technically mature and not the focus of this application, it will only be briefly described here and will not be elaborated further. The cutting mechanism 200 includes two auxiliary augers 210 and one main auger 220. Both ends of the auxiliary augers 210 and both ends of the main auger 220 are rotatably connected to two opposite sidewalls of the working chamber 110 (the outer wall of the working chamber 110 is provided with bearings corresponding to the auxiliary augers 210 and the main auger 220). The two auxiliary augers 210 are spaced apart along the width of the working chamber 110. The main auger 220 is located below the auxiliary augers 210 and between the two auxiliary augers 210. One end of the main auger 220 extends out of the working chamber 110 and is connected to a first sprocket 221. One end of the auxiliary auger 210 extends out of the working chamber 110 and is connected to a second sprocket 211. Another auxiliary auger 210 extends out of the working chamber 110 and is connected to a first gear 212. The outer wall of the machine body 100 is provided with a rotatable rotating rod 120. A third sprocket 121 and a second gear 122 are fixed on the rotating rod 120. The third sprocket 121 is located between the second gear 122 and the machine body 100. The first sprocket 221, the second sprocket 211, and the third sprocket 121 are connected by a chain 230, and the first gear 212 and the second gear 122 mesh. In this application, the length direction of the working chamber 110 is the axial direction of the main auger 220, and the width direction of the working chamber 110 is the direction perpendicular to the main auger 220. This is specifically stated here and will not be repeated hereafter.

[0027] The drive unit 300 is connected to the main auger 220 to drive the main auger 220 and the two auxiliary augers 210 to rotate synchronously, and drives the two auxiliary augers 210 to rotate in opposite directions through the first gear 212 and the second gear 122. In this embodiment, the drive unit 300 is a motor. In other embodiments, the drive unit 300 may also be a tractor engine.

[0028] Understandably, when the feed mixer is working, the drive unit 300 drives the main auger 220 to rotate. The main auger 220 drives the chain 230, the second sprocket 211, and the third sprocket 121 to rotate via the first sprocket 221. The third sprocket 121 drives the first gear 212 to rotate via the rotating rod 120 and the second gear 122, thereby driving the two auxiliary augers 210 to rotate in opposite directions. The two auxiliary augers 210 rotating in opposite directions can guide the feed between the two auxiliary augers 210 to fall quickly onto the main auger 220. At the same time, it guides the feed between the auxiliary augers 210 and the inner wall of the adjacent working chamber 110 to move from bottom to top to the top of the auxiliary augers 210, realizing the circumferential circulation of the feed along the auxiliary augers 210. The two auxiliary augers 210 and the main auger 220 cooperate to quickly cut the feed.

[0029] By setting the first gear 212 and the second gear 122, the two auxiliary augers 210 can be driven to rotate in opposite directions, preventing feed from getting stuck, reducing the load on the drive unit 300 and effectively improving the cutting efficiency of the feed mixer. It can also simplify the transmission structure between the auxiliary auger 210 and the main auger 220 and reduce the operating cost of the cutting mechanism 200.

[0030] Reference Figure 1 As shown, it can be understood that both the main auger 220 and the two auxiliary augers 210 have helical cutting blades 213. The helical cutting blades 213 of the two auxiliary augers 210 rotate in opposite directions, and the helical cutting blades 213 of the main auger 220 rotate in the same direction as the helical cutting blades 213 of the auxiliary auger 210 (i.e., the auxiliary auger 210 that rotates in the opposite direction to the main auger 220) connected to the first gear 212. Optionally, the cutting blades 213 can be a spiral structure that extends from one end of the main auger 220 (or auxiliary auger 210) to the other end along the axial direction of the main auger 220 (or auxiliary auger 210) and rotates multiple times. Multiple cutting blades 213 can also be provided, with a single cutting blade 213 spirally wound once along the axial direction of the main auger 220 (or auxiliary auger 210), and multiple cutting blades 213 spaced apart along the axial direction of the main auger 220 (or auxiliary auger 210).

[0031] The cutting blades 213 of the main auger 220 and the cutting blades 213 of the auxiliary auger 210, which rotate in the opposite direction to the main auger 220, are set in the same direction. This allows the main auger 220 to transport feed from back to front along the length of the reaction chamber, while the two auxiliary augers 210 transport feed from front to back along the length of the reaction chamber, achieving cyclical movement of feed along the length of the reaction chamber. Compared to traditional feed cutters that can only transport feed unidirectionally from back to front along the length of the reaction chamber, this application can add more feed to the reaction chamber, and the top surface of the feed remains flat, preventing accumulation at the rear of the reaction chamber, effectively expanding the feed processing capacity of the feed mixer.

[0032] Reference Figure 2As shown (driving component 300 omitted), it can be understood that the side wall of the machine body 100 is also provided with a tensioning wheel 140 that can move along the width direction of the working cavity 110. Specifically, the side wall of the machine body 100 is provided with a sliding groove extending along the width direction of the working cavity 110, and the tensioning wheel 140 is provided with an insertion part that engages with the sliding groove. The tensioning wheel 140 and the chain 230 are in rolling friction engagement, and the tensioning wheel 140 and the first sprocket 221 are respectively located on both sides of the chain 230.

[0033] By setting a tension wheel 140 that can move laterally, the user can adjust the position of the tension wheel 140 laterally to adjust the stress between the chain 230 and the first sprocket 221, the second sprocket 211, and the third sprocket 121, thereby eliminating the frictional loss of the first sprocket 221 and the second sprocket 211 and improving the transmission efficiency of the first sprocket 221 and the second sprocket 211.

[0034] Reference Figure 1 and Figure 2 As shown, it can be understood that the feed mixer also includes a control box 400, which is located on one side of the drive unit 300 and electrically connected to the drive unit 300.

[0035] The control box 400 is located on one side of the drive unit 300, which makes it convenient for users to adjust the speed of the drive unit 300 in a timely manner. Users can reduce the speed of the drive unit 300 when less feed is added and increase the speed of the drive unit 300 when more feed is added, thereby improving the controllability of the feed mixer and avoiding energy waste.

[0036] Reference Figure 2 and Figure 3 As shown, it can be understood that a vertical support plate 130 is fixed to the side wall of the body 100, and two bearing seats 131 are spaced apart on the support plate 130. The two ends of the rotating rod 120 are rotatably mounted on the two bearing seats 131, and the support plate 130 has a hollow structure for the chain 230 to pass through.

[0037] By supporting the rotating rod 120 with two bearing seats 131, the rotational stability of the rotating rod 120 is effectively improved, thereby increasing the synchronization rate of the two auxiliary screw conveyors 210. The two bearing seats 131 are fixed to the support plate 130, which simplifies the connection structure between the rotating rod 120 and the machine body 100 and reduces the arrangement cost of the rotating rod 120.

[0038] Reference Figure 3 As shown, it can be understood that the support plate 130 has flanged portions 132 on both sides in the vertical direction. The flanged portions 132 extend along the width direction of the reaction chamber. The flanged portions 132 are welded with first nuts 133. The side wall of the machine body 100 is provided with two second nuts 150 at intervals in the vertical direction. The second nuts 150 and the first nuts 133 correspond one-to-one and are bolted together.

[0039] By setting the flange 132 and the first nut 133, the flange 132 can increase the thickness of the support plate 130, thereby effectively supporting the first nut 133. The first nut 133 and the second nut 150 are bolted together, which improves the installation stability of the rotating rod 120 and facilitates the user to disassemble the support plate 130 for inspection, maintenance or replacement of the bearing seat 131, the rotating rod 120 and the second gear 122, thereby reducing the maintenance cost of the feed mixer in the later stage.

[0040] Continue to refer to Figure 1 As shown, it can be understood that the cutting blade 213 of the main auger 220 is connected to a detachable blade assembly 222 along the edge of the main auger 220, and the blade assembly 222 protrudes from the main auger 220 radially.

[0041] By setting up the blade assembly 222, which replaces part of the cutting blade 213 to cut feed, when the feed mixer runs for a long time and the blade assembly 222 becomes dull, the user can replace it with a new blade assembly 222 to ensure the cutting efficiency of the cutting blade 213 without replacing the entire main auger 220, thus effectively extending the service life of the main auger 220.

[0042] Furthermore, the blade assembly 222 includes a main cutter 2221, which is bolted to the cutting disc 213. The main cutter 2221 has a curved triangular shape, and the curved sides of the curved triangular cutter are provided with serrations.

[0043] By setting a serrated main cutter 2221, when the main auger 220 rotates, the serrations of the main cutter 2221 can increase the contact area between the blade assembly 222 and the feed, thus greatly improving the cutting efficiency of the blade assembly 222.

[0044] Furthermore, the blade assembly 222 also includes multiple scalloped blades 2222, which are bolted to the cutting disc 213, and the multiple scalloped blades 2222 are spaced apart along the spiral direction of the cutting disc 213.

[0045] By setting multiple plum blossom blades 2222, and having multiple plum blossom blades 2222 work together, the contact area between the blade assembly 222 and the feed can be further increased, improving the cutting efficiency of the blade assembly 222 while reducing the arrangement cost of the blade assembly 222.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
