[0022] Refer to Figures 1 to 3 As shown, a vertical feed mixer provided by an embodiment of the present utility model includes a frame 100, a blade assembly 200, and a drive assembly 300.

[0023] The frame 100 is provided with a mixing tank 110 and an auger 120. The mixing tank 110 is provided with a mixing shaft 111 which is vertically arranged. The auger 120 is spirally wound around the outer periphery of the mixing shaft 111 from bottom to top. The auger 120 is in a conical shape with a smaller top and a larger bottom to convey feed from bottom to top and make the feed fall from the top of the auger 120; a hydraulically driven hatch 112 is provided on the side wall of the mixing tank 110, and the hatch 112 is used to open or close the mixing tank 110.

[0024] The blade assembly 200 includes a plurality of serrated blades 210, a plurality of plum blossom blade groups 220, and a plurality of fixed blades 230. The serrated blades 210 are blades with a fan-shaped appearance and a plurality of serrations arranged on the arc edge. The serrated blades 210 and the plum blossom blade groups 220 are arranged at intervals along the spiral direction of the auger 120 on the side of the auger 120 away from the stirring shaft 111. The plurality of fixed blades 230 are arranged at intervals along the circumference of the stirring shaft 111 and arranged around the outer periphery of the auger 120, and along the height direction, the height of the fixed blades 230 is located below the height of the top surface of the auger 120. Optionally, the fixed blades 230 can be arranged around the auger 120 in one circle, and can be arranged around the auger 120 in multiple circles up and down, which will not be repeated here.

[0025] The driving assembly 300 includes a motor 310 and a first gearbox 320. The first gearbox 320 is mounted on the frame 100. The motor 310 is connected to the stirring shaft 111 through the first gearbox 320. The first gearbox 320 has a plurality of speed adjustment gears with increasing output speeds. The first gearbox 320 is provided with a lever 321 for adjusting the gear. The lever 321 extends upward and is located on one side of the stirring box 110. It should be noted that the gearbox with multiple speed adjustment gears belongs to the existing mature technology, and its specific composition structure will not be described in detail.

[0026] It can be understood that by setting up the first gearbox 320, the user can control the rotation speed of the stirring shaft 111 and the auger 120 through the first gearbox 320. The user only needs to move the lever 321 to control the first gearbox 320 to switch gears, eliminating the control structure of the traditional variable frequency motor 310 (such as inverter, PLC, etc.), simplifying the structure and control steps of the drive component 300, and facilitating user control and use and reducing subsequent maintenance costs; when facing feed of different lengths, the user can increase or decrease gears according to the length of the forage. For example, when the feed is longer, the gear of the first gearbox 320 can be increased by the lever 321, thereby increasing the rotation speed of the auger 120. When the feed is shorter, the gear of the first gearbox 320 can be lowered by the lever 321, thereby reducing the rotation speed of the auger 120. The first gearbox 320 cooperates with the serrated blade 210, the plum blossom knife group 220 and the fixed blade 230 arranged on the inner wall of the mixing box 110 to cut the feed 360° without dead angles, and the plum blossom knife group 220 can cut the feed twice to ensure the mixing and cutting effects.

[0027] Furthermore, the frame 100 is provided with two mounting beams, and the two mounting beams are spaced apart to form an installation space for the first gearbox 320 to pass through. The mounting beams are provided with mounting plates, and the mounting plates of the two mounting beams are arranged opposite to each other and both extend downward, and the two mounting plates are respectively connected to the two sides of the first gearbox 320 by bolts.

[0028] By setting a mounting plate to fix the first gearbox 320, on the one hand, the mounting structure of the gearbox can be simplified, and it is convenient for users to load and unload the first gearbox 320; on the other hand, the mounting beams are arranged at intervals, and the mounting plate is extended downward, so that the first gearbox 320 is installed below the frame 100 and the top of the gearbox is hollowed out, which can avoid interference between the first gearbox 320 and other components on the frame 100 (such as the drive device of the hatch 112, etc.), thereby improving the structural rationality of the mixer, and it is also convenient for users to inspect and adjust the gearbox, and avoid the mounting beam affecting the installation and movement of the lever 321.

[0029] Reference Figure 2 As shown, it can be understood that a reducer 130 and a transmission shaft 140 are also provided between the stirring shaft 111 and the first gearbox 320. The reducer 130 is arranged at the bottom end of the frame 100 and connected to the stirring shaft 111. The reducer 130 reduces the speed of the stirring shaft 111 through a planetary gear structure, and both ends of the transmission shaft 140 are respectively connected to the reducer 130 and the output end of the first gearbox 320 through a cross universal coupling.

[0030] Since the first gearbox 320 is arranged below the mounting beam, there is a certain height difference between the first gearbox 320 and the reducer 130. By arranging the transmission shaft 140, the cross universal couplings at both ends of the transmission shaft 140 can absorb the height difference and installation error between the first gearbox 320 and the reducer 130, ensuring that the power of the first gearbox 320 can be stably transmitted to the reducer 130, effectively improving the working stability of the stirring shaft 111. In addition, the transmission shaft 140 is arranged between the first gearbox 320 and the reducer 130 to replace the traditional belt transmission, avoiding slippage, loss of rotation, etc., and further improving the working stability of the stirring shaft 111.

[0031] Furthermore, the frame 100 is provided with a spare shaft 150, which is located on the side of the reducer 130 away from the motor 310 and is transmission-connected to the reducer 130. The connection structure between the spare shaft 150 and the reducer 130 can refer to the previous description of the transmission shaft 140 and will not be repeated here.

[0032] By providing a spare shaft 150 connected to the reducer 130, when the motor 310 or the first gearbox 320 fails, the user can connect an external spare motor 310 or a tractor engine, etc., to add a spare power source for the stirring shaft 111 outside the motor 310, thereby improving the fault tolerance of the mixer.

[0033] Reference Figure 1 and Figure 2 As shown, it can be understood that the frame 100 is installed with a second gearbox 160, the second gearbox 160 is connected to the spare shaft 150, and the second gearbox 160 also has a plurality of speed regulating gears with sequentially increasing output speeds.

[0034] By setting the second transmission 160, when the user drives the auger 120 using the spare shaft 150, the rotation speed of the auger 120 can also be adjusted, reducing the difference between the two drive structures. The user can freely switch between the two drive structures (when one of the first transmission 320 and the second transmission 160 is working, the other is shifted to neutral to avoid damage), increasing the working time of the mixer and improving the working efficiency of the mixer.

[0035] Furthermore, the projection of the spare shaft 150 on the horizontal plane is coaxial with the projection of the transmission shaft 140 on the horizontal plane. In other words, the axis of the spare shaft 150 and the axis of the transmission shaft 140 are parallel or collinear.

[0036] Setting the axis of the spare shaft 150 parallel to the axis of the transmission shaft 140, connecting the spare shaft 150 and the transmission shaft 140 to both sides of the same position of the reducer 130, eliminating the need for additional gear transmission, simplifying the planetary gear structure inside the reducer 130, and reasonably utilizing the installation space on the side of the reducer 130 away from the motor 310, avoiding increasing the lateral dimension of the mixer and improving the space utilization rate of the mixer.

[0037] Refer to Figure 3 As shown, it can be understood that the plum blossom knife group 220 includes multiple plum blossom blades, and the multiple plum blossom blades are arranged at intervals along the circumferential direction of the stirring shaft 111. Specifically, the plum blossom blade is a blade with an oval shape and serrations on the outer circumference. Optionally, the fixed blade 230 can be set as a plum blossom blade to improve the structural consistency of the blade assembly 200, or it can be set as an ordinary blade to reduce the manufacturing cost.

[0038] By arranging multiple plum blossom blades in the plum blossom knife group 220, when the auger 120 rotates, the multiple plum blossom blades can cut the feed between adjacent serrated blades 210, or cut the feed that has been cut once by the serrated blade 210. The multiple plum blossom blades cooperate with the fixed blade 230 outside the auger 120 to finely cut the feed between the auger 120 and the inner wall of the mixing tank 110, greatly enhancing the cutting effect of the blade assembly 200.

[0039] Furthermore, the multiple plum blossom blades arranged between any two adjacent serrated blades 210 are equal, that is, the number, spacing, included angle, etc. of the multiple plum blossom knives in each plum blossom knife group 220 are arranged in the same way.

[0040] Since the auger 120 is in a conical shape with a smaller upper part and a larger lower part, along the height direction, the outer diameter of the auger 120 decreases successively from bottom to top. This results in that for each rotation of the auger 120, the spacing between the adjacent serrated blades 210 also decreases. By arranging multiple plum blossom blades between two adjacent serrated blades equally, on the one hand, the consistency of the structure of the blade assembly 200 can be improved. The spacing arrangement of the plum blossom blades on the auger 120 is relatively fixed, which is convenient for users to design and process the auger 120. On the other hand, it is ensured that the cutting effect of the plum blossom blades will not change with the change of the outer diameter of the auger 120, and the consistency of the cutting effect of the plum blossom knife group 220 is guaranteed.

[0041] Furthermore, the serrated blade 210 is inclined upward along the radial direction of the stirring shaft 111 from the end close to the auger 120 towards the end far from the auger 120.

[0042] Since the auger 120 is spirally wound around the stirring shaft 111 and the auger 120 itself is usually inclined relative to the horizontal plane, on the basis of the inclination of the auger 120, the serrated blade 210 is further inclined. Compared with the blades of the traditional mixer being parallel to the plane where the auger 120 is located, the inclined serrated blade 210 expands its contact position with the feed in the axial direction of the stirring shaft 111. Although its contact position with the feed in the radial direction of the stirring shaft 111 decreases, the fixed blade 230 arranged on the outer side of the auger 120 can make up for or even increase the reduced contact part of the serrated blade 210, thereby optimizing the arrangement of the blade assembly 200, improving the utilization rate of the blade assembly 200, and enhancing the cutting efficiency of the mixer.

[0043] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
