Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1:

[0024] As Figures 1 to 7 shown, a mixing device for producing piglet feed containing whey powder with different proportions includes a mixing cylinder 101. An upper cover plate 106 is fixedly connected to the mixing cylinder 101. An upper shell 107 is fixedly connected to the upper cover plate 106. A cross bar 116 is slidably connected to the upper shell 107. A knocking rod 119 is rotatably connected to the cross bar 116. The first end of a torsion spring 118 is fixedly connected to the knocking rod 119. The second end of the torsion spring 118 is rotatably connected to the cross bar 116. The knocking rod 119 also contacts the outer wall of the mixing cylinder 101. A main shaft 111 is rotatably connected to the cross bar 116. A stirring rod 121 is fixedly connected to the main shaft 111. The stirring rod 121 is also rotatably connected to the inner wall of the mixing cylinder 101.

[0025] One end of a support rod 102 is fixedly connected to the mixing cylinder 101. The other end of the support rod 102 is rotatably connected to a support frame 103. A side motor 104 is fixedly installed on the support frame 103. The output shaft of the side motor 104 is fixedly connected to the other end of the support rod 102. A sealing plate 105 is arranged on the mixing cylinder 101. A support 109 is fixedly connected to the upper cover plate 106. A main motor 110 is fixedly installed on the support 109. The output shaft of the main motor 110 is fixedly connected to a main shaft 111.

[0026] During use, the side motor 104 rotates the support rod 102, and the support rod 102 then drives the mixing cylinder 101 to rotate around the axis of the support rod 102, so that the sealing plate 105 on the mixing cylinder 101 rotates above the support rod 102, thereby facilitating the addition of materials and checking whether there is any residue on the inner wall of the mixing cylinder 101.

[0027] When putting in the materials, open the sealing plate 105, put the pre-prepared whey powder and other mixed materials into the mixing cylinder 101 together in proportion, then close the sealing plate 105, and rotate the mixing cylinder 101 in the reverse direction to make the sealing plate 105 return to the lower end, and then carry out the mixing process. During mixing, the main motor 110 drives the main shaft 111, and the main shaft 111 drives the stirring rod 121 to rotate on the inner wall of the mixing cylinder 101, so as to stir the whey powder and other mixed materials in the mixing cylinder 101. The stirring rod 121 is close to the inner wall of the mixing cylinder 101, and the adhered materials on the inner wall can be scraped off during stirring to avoid uneven mixing.

[0028] When the main shaft 111 rotates, it will also drive the cross bar 116 to slide horizontally back and forth on the water spraying disc 117, so that the knocking rods 119 at both ends of the cross bar 116 approach and move away from the mixing cylinder 101. In the initial state, the knocking rods 119 on both sides are in contact with the outer wall of the mixing cylinder 101. When the cross bar 116 moves, the knocking rod 119 moving towards the mixing cylinder 101 twists the torsion spring 118 on the cross bar 116 under the block of the mixing cylinder 101, while on the other side, that is, the knocking rod 119 moving away from the mixing cylinder 101 separates from the outer wall of the mixing cylinder 101 and the torsion spring 118 does not twist. When the cross bar 116 moves in the reverse direction, the knocking rod 119 that was previously away from the mixing cylinder 101 becomes the one moving towards the mixing cylinder 101, so that the knocking rod 119 contacts and knocks on the outer wall of the mixing cylinder 101, and then the cross bar 116 continues to move, and the cross bar 116 on this side pulls the knocking rod 119, thereby twisting the torsion spring 118, while on the other side, that is, the knocking rod 119 that was previously close to the mixing cylinder 101, moves away from the mixing cylinder 101, so that the knocking rods 119 on both sides alternately knock on the outer wall of the mixing cylinder 101.

[0029] Under the action of the torsion spring 118, the knocking rod 119 knocks on the outer wall of the mixing cylinder 101, causing the mixing cylinder 101 to vibrate, so that the materials on the inner wall of the mixing cylinder 101 that have not been scraped off by the stirring rod 121 are shaken off. When discharging is required after mixing is completed, there is no need to control the rotation of the mixing cylinder 101. Keep the sealing plate 105 at the lower end, open the sealing plate 105, the materials fall by their own gravity, and start the main motor 110 to control the rotation of the stirring rod 121 in the mixing cylinder 101 to scrape off the materials remaining on the inner wall of the mixing cylinder 101. At the same time, through the knocking of the cross bar 116 on the mixing cylinder 101, the materials still remaining on the mixing cylinder 101 and the stirring rod 121 fall, so as to ensure that there is no material residue and avoid cross-contamination in the next mixing, affecting the mixing ratio of the whey powder for piglets.

[0030] Observe through the opening at the sealing plate 105 of the mixing cylinder 101. If there is a large amount of residual material in the mixing cylinder 101, an external water pipe can be connected to the water injection pipe 108 to inject water into the mixing cylinder 101 and clean it under the stirring of the stirring rod 121, so as to avoid residue.

[0031] Embodiment 2:

[0032] As Figures 3 to 7 shown, two limit blocks 120 are fixedly connected to the upper cover plate 106, and the first end of a connecting shaft 114 is slidably connected to each limit block 120, and an eccentric cam 115 is fixedly connected to the second end of the connecting shaft 114.

[0033] An intermediate gear 112 is fixedly connected to the main shaft 111, a side gear 113 is fixedly connected to the connecting shaft 114, and the intermediate gear 112 meshes with the side gear 113.

[0034] The cross bar 116 is provided with a chute and a hole, the connecting shaft 114 is rotatably connected to the hole of the cross bar 116, and the main shaft 111 is slidably connected to the chute of the cross bar 116.

[0035] In use, the main shaft 111 drives the intermediate gear 112 to rotate. Since the intermediate gear 112 meshes with the side gears 113 on both sides, the intermediate gear 112 drives the side gears 113 on both sides to rotate. Furthermore, the side gears 113 on both sides each drive a connecting shaft 114 to rotate on the cross bar 116, so that the eccentric cams 115 on the connecting shafts 114 rotate. Through the eccentric action of the eccentric cams 115, the connecting shafts 114 and the cross bar 116 are driven to slide horizontally back and forth on the limit blocks 120. The eccentric cams 115 on both sides are arranged in the same direction, that is, the eccentric directions of the two eccentric cams 115 are the same. Thus, when the eccentric cams 115 rotate, the connecting shafts 114 are driven to slide horizontally back and forth on the limit blocks 120. And there is a relatively large gap between the side gears 113 on the connecting shafts 114 and the intermediate gear 112, that is, the tooth pitch is large and the teeth are long. Therefore, when the side gears 113 follow the connecting shafts 114 to move horizontally back and forth, it does not affect the meshing relationship between the side gears 113 and the intermediate gear 112. Furthermore, the connecting shafts 114 drive the cross bar 116 to reciprocate on the upper shell 107, driving the knocking rod 119 to knock on the outer wall of the mixing cylinder 101.

[0036] A water injection pipe 108 is fixedly installed on the upper cover plate 106. A water spraying disc 117 is fixedly connected to the water injection pipe 108. A plurality of water spraying holes are arranged on the water spraying disc 117. The water spraying disc 117 is also fixedly installed on the inner wall of the mixing cylinder 101.

[0037] In use, water is injected into the water spraying disc 117 through the water injection pipe 108, and then the inner wall of the mixing cylinder 101 and the stirring rod 121 are sprayed with water through the water spraying disc 117, so as to clean the stirring rod 121 and the inner wall of the mixing cylinder 101. And by driving the stirring rod 121 to rotate, the water is driven to flow in the mixing cylinder 101, further cleaning the residual materials on the stirring rod 121 and on the side of the mixing cylinder 101 close to the sealing plate 105. Since this side is the main mixing area, the materials are mainly concentrated on the side of the mixing cylinder 101 close to the sealing plate 105. Thus, through the cleaning of the mixing cylinder 101, cross contamination is avoided when mixing whey powder with the same ratio and different ratios.

[0038] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Any simple modification or equivalent change made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
