Description

Technical Field

[0001] The invention relates to the technical field of feed mixing in aquaculture, and in particular to a mixer. Background Art

[0002] In the poultry farming industry, in order to ensure balanced nutrition, it is necessary to mix a variety of different feeds before feeding. The manual mixing work is large and it is difficult to ensure uniform mixing. In order to facilitate poultry feeding, poultry feed is generally made into granules. If the traditional stirring mixing method is used to mix the feed, it is easy to break the granular feed, which is not convenient for poultry to eat and may cause waste. In addition, when the amount of feed is large, the driving force requirements are high, and the requirements for equipment are also increased, and the cost is high. Therefore, a drum mixer is more suitable for feed mixing. However, the drum mixer also exposes some problems during specific use. For example, a material cover needs to be set at the feed port for feeding or discharging. Each time feeding or discharging needs to be opened or closed, the operation is relatively cumbersome, and the material cover will rotate at high speed with the drum, so the fastening requirements of the material cover are high; in addition, when the amount of feed to be mixed is large, only one feed port will obviously reduce the efficiency of feeding or discharging. However, if multiple feed ports are set, the operation of opening and closing the material cover will be more cumbersome, reducing work efficiency. Summary of the invention

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further specifically described below through embodiments in conjunction with the accompanying drawings.

[0027] Example 1

[0028] A mixer according to the present embodiment, such as Figure 1-6 As shown, it includes a frame 1, a first rotating shaft 2, a second rotating shaft 3, an outer barrel 4, an inner barrel 5, a mixing motor and two sets of reversing components 6, wherein the first rotating shaft 2 and the second rotating shaft 3 are respectively installed at both ends of the frame 1 through bearings, and the two are located on the same straight line, and are respectively used to drive the outer barrel 4 and the inner barrel 5 to rotate. The outer barrel 4 is sleeved outside the inner barrel 5, and the surface of the outer barrel 4 is provided with two outer barrel material openings 41 at the same angle interval, and correspondingly, the surface of the inner barrel 5 is provided with two inner barrel material openings 51. Two hole-shaped feed hoppers 7 are provided at corresponding positions on the top of the frame 1 for feeding; two discharge channels 8 are provided at corresponding positions on the bottom of the frame 1 for discharging. The output shaft of the mixing motor (not shown in the figure) is connected to the first rotating shaft 2.

[0029] In this embodiment, the outer barrel 4 is a cylindrical shape with two ends open, and the two ends thereof are respectively extended outward to be provided with an outer barrel wheel frame 42, wherein the axis position of the outer barrel wheel frame 42 at one end is interference fit with the first rotating shaft 2, and the axis position of the outer barrel wheel frame 42 at the other end is relatively rotatably connected to the second rotating shaft 3 through a bearing, and the mixing motor drives the first rotating shaft 2 to rotate, thereby driving the outer barrel 4 to rotate. The inner barrel 5 is a cylindrical shape with two ends closed, and its outer surface is gap-fitted with the inner surface of the outer barrel 4, and the two ends of the inner barrel 5 are respectively extended outward to be provided with an inner barrel wheel frame 52, wherein the axis position of the inner barrel wheel frame 52 at one end is interference fit with the second rotating shaft 3, and the axis position of the inner barrel wheel frame 52 at the other end is relatively rotatably connected to the first rotating shaft 2 through a bearing. The first rotating shaft 2 only directly drives the outer barrel 4 to rotate, and the second rotating shaft 3 only directly drives the inner barrel 5 to rotate.

[0030] Specifically, the outer barrel wheel frame 42 and the inner barrel wheel frame 52 are respectively composed of four L-shaped brackets in a cross shape, and the radial dimension of the outer barrel wheel frame 42 is larger than the radial dimension of the inner barrel wheel frame 52 to avoid interference when the two rotate relative to each other.

[0031] In the above structure, the circumferential position of the material opening 51 on the surface of the inner barrel 5 corresponds to one of the L-shaped brackets, and a mark is marked on the L-shaped bracket. When the position of the inner barrel material opening 51 cannot be directly observed from the outside, the angular position of the inner barrel material opening 51 can be determined by the mark.

[0032] In this embodiment, the reversing assembly 6 is arranged between the outer barrel wheel frame 42 and the inner barrel wheel frame 52, with one group arranged at each end, and they are symmetrical to each other. The reversing assembly 6 includes a first reversing sleeve 61 and a second reversing sleeve 62, the bases of which are both annular, and are fixedly mounted on the opposite sides of the outer barrel wheel frame 42 and the inner barrel wheel frame 52, respectively, and the first reversing sleeve 61 and the second reversing sleeve 62 are both clearance-matched with the first rotating shaft 2 or the second rotating shaft 3, and the end faces of the first reversing sleeve 61 and the second reversing sleeve 62 are contact-matched or clearance-matched. An angle groove 63 is provided on one side of the first reversing sleeve 61 close to the second reversing sleeve 62, and the angle groove 63 is provided along the edge of the first reversing sleeve 61 at a certain angle. In this embodiment, the angle of the angle groove 63 is 90°, and a protrusion 64 matching the angle groove 63 is provided on one side of the second reversing sleeve 62 close to the first reversing sleeve 61. In this embodiment, the protrusion 64 is one-eighth of an annular shape, that is, the angle is 45°. When the inner and outer barrels rotate relative to each other, the projection 64 rotates in the angle groove 63, and the maximum rotation angle is 45°.

[0033] In this embodiment, the outer end of the second rotating shaft 3 is detachably connected to a crank (not shown in the figure), and the second rotating shaft 3 can be manually driven to rotate by the crank, thereby driving the inner barrel 5 to rotate.

[0034] In this embodiment, when the protrusion 64 contacts one side wall of the angle groove 63, the outer barrel material opening 41 and the inner barrel material opening 51 are aligned with each other. Therefore, when feeding, first align the outer barrel material opening 41 and the inner barrel material opening 51 upward and align them with the feed hopper 7, and then add the feed to be mixed into the inner barrel 5 through the feed hopper 7, and the protrusion 64 contacts one side wall of the angle groove 63. When mixing, turn on the mixing motor to drive the outer barrel 5 to rotate, so that the protrusion 64 first rotates 45° relative to the angle groove 63 until it contacts the other side of the angle groove 63. During this process, the outer barrel 4 rotates relative to the inner barrel 5 while the inner barrel 5 remains stationary, and the positions of the outer barrel material opening 41 and the inner barrel material opening 51 will be staggered, so that the inner barrel material opening 51 is blocked; when the protrusion 64 contacts the other side of the angle groove 63, the outer barrel 4 will drive the inner barrel 5 to rotate together, so that the feed inside the inner barrel 5 is shaken and mixed. When mixing materials, the crank handle at the end of the second rotating shaft 3 needs to be removed to prevent the crank handle from causing harm to surrounding personnel when rotating at high speed.

[0035] After the feed in the inner barrel 5 is mixed evenly, turn off the mixing motor, and then install a crank at the end of the second rotating shaft 3. After the installation of the crank, first manually drive the second rotating shaft 3 to rotate in the opposite direction of the mixing motor during mixing through the crank, the second rotating shaft 3 drives the inner barrel 5 to rotate, and the inner barrel 5 will drive the outer barrel 4 to rotate together; when the outer barrel material opening 41 on the surface of the outer barrel 4 is aligned with the discharge channel 8 at the bottom of the frame, the crank stops rotating, and then rotates the crank in the opposite direction, at this time the inner barrel 5 rotates while the outer barrel 4 remains stationary, and observe the position of the marked L-shaped bracket at the same time. When the marked L-shaped bracket is vertically downward, stop rotating the crank, and at this time the inner barrel material opening 51 is aligned with the outer barrel material opening 41, and the material can be discharged.

[0036] Example 2

[0037] The difference between this embodiment and embodiment 1 is that in this embodiment, the second rotating shaft 3 is driven to rotate by a reset motor (not shown in the figure) to realize the automatic discharging operation. In this embodiment, the reset motor is a code disc motor, specifically, a stepping motor with an encoder can be used. After the mixing is completed, the target position of the inner barrel material opening 51 is set downward, and then the inner barrel 5 is driven by the reset motor to rotate in the same direction along the rotation direction of the mixing motor. At this time, the outer barrel 4 remains stationary until the protrusion 64 contacts the other side of the angle groove 63, thereby driving the outer barrel 4 to rotate together, and at this time, the outer barrel material opening 41 is aligned with the inner barrel material opening 51; when the reset motor drives the inner barrel 5 and the outer barrel 4 to rotate until the inner barrel material opening 51 and the outer barrel material opening 41 are both vertically downward, the material can be discharged.

[0038] In specific practice, when the resolution of the encoder is 4000 lines, the inner barrel material opening 51 and the outer barrel material opening 41 can be aligned with the discharge channel 8 more accurately.

[0039] Finally, it should be pointed out that the above embodiments are only representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention should be considered to belong to the protection scope of the present invention.
