Technical Field

[0001] The invention relates to the field of feed preparation, in particular to a growth-promoting pig feed and a preparation method thereof. Background Art

[0002] Pig feed processing involves the process of treating and processing various feed ingredients into feed products suitable for pigs at different growth stages. The goal is to improve the nutritional value, palatability, digestibility, and storage stability of the feed. Pig feed processing typically includes raw material receiving and cleaning, crushing, batching, mixing, pelleting, cooling and drying, screening, and packaging.

However, most pelleting equipment using this pelleting method cannot spread the raw materials flat on the forming plate. Due to the unevenness of the raw materials, the raw materials at the bottom will not be able to squeeze into the forming holes, thus affecting the pelleting efficiency. Summary of the Invention

[0032] like Figure 1-9 As shown, a device for preparing growth-promoting pig feed is described in detail:

[0033] A device for preparing growth-promoting pig feed includes a forming ring disk 101 with multiple forming holes 104 evenly penetrated therethrough, a heating sleeve being provided at the lower end of the inner wall of each forming hole 104, an inner tube rack 201 rotating in the inner hole of the forming ring disk 101, multiple pressure rollers 202 rotating evenly circumferentially on the inner tube rack 201, and multiple pressure rollers 202 rolling on the upper end surface of the forming ring disk 101, two support plates 105 being symmetrically provided on the outer side of the forming ring disk 101, a ring rack 107 coaxial with the forming ring disk 101 being fixed at the upper end of the two support plates 105, a material box 301 rotating in the ring rack 107, a multiple drop pipes 302 extending evenly circumferentially from the lower part of the material box 301 with ports aligned with the upper end surface of the forming ring disk 101, and the multiple drop pipes 302 and the multiple pressure rollers 202 being arranged in sequence at intervals.

[0034] During use, the mixed powdered raw materials are heated and humidified with steam and then added into the feed box 301. Then, the inner tube rack 201 is driven to rotate in the inner hole of the forming ring disk 101, thereby driving multiple pressing rollers 202 to roll on the upper end surface of the forming ring disk 101. At the same time, the feed box 301 is driven to rotate synchronously with the inner tube rack 201 in the ring rack 107, thereby making each drop tube 302 rotate synchronously between two adjacent pressing rollers 202, and spreading the raw materials from the lower end of the drop tube 302 onto the forming ring disk 101, so that the pressing roller 202 at the rear rolls the raw materials into the forming hole 104, so that the raw materials are compressed into a columnar shape in the forming hole 104 and slide out from the lower end of the forming hole 104. As the raw materials continue to grow, their own gravity increases, and they will break and fall, thereby "breaking" into small particles to obtain pig feed.

[0035] The forming hole 104 has a large upper end, a small lower end, and a tapered surface in the middle. During extrusion, the raw material is rolled by the roller 202 to the upper large-diameter forming hole 104. As the raw material continues to be rolled, it contracts and presses through the tapered surface into the lower small-diameter forming hole 104, and then slides out from the lower end of the forming hole 104. The heating jacket is located on the inner wall of the small-diameter hole at the lower end of the forming hole 104. When the heating jacket is energized, it heats up, thereby heating and expanding the forming material located there, thereby directly obtaining expanded particles.

[0036] It should be noted that there is a certain gap between the lower end of the blanking tube 302 and the upper end face of the forming ring disk 101. This gap is the thickness of the flattened raw material. Moreover, the blanking tube 302 is fan-shaped as a whole, and its width matches the forming ring disk 101. Then, the lower end edge of the end face at the front end of the blanking tube 302 will also push and scrape the material on the upper end face of the forming ring disk 101.

[0037] Another embodiment of the present application is:

[0038] A rotary sleeve is rotatably mounted on the lower end of the forming ring disc 101, and a cutter is fixed on the rotary sleeve. The cutter is attached to the lower end surface of the forming ring disc 101, so that when the rotary sleeve is driven, the cutter can be driven to rotate on the lower end surface of the forming ring disc 101, thereby cutting the forming column after sliding out of the lower end of the forming hole 104, thereby obtaining particles. This embodiment is not shown in the figure.

[0039] Further:

[0040] The outer ring and inner ring of the upper end of the molded ring disk 101 are respectively provided with an outer retaining ring 102 and an inner retaining ring 103.

[0041] By setting the outer retaining ring 102 and the inner retaining ring 103, the inner and outer circles of the upper end surface of the forming ring disk 101 can be blocked, thereby preventing the raw material sliding down the lower end of the blanking tube 302 from falling off the forming ring disk 101.

[0042] Further:

[0043] A conical barrel 303 is provided in the middle of the material box 301 for allowing the raw materials in the material box 301 to slide into the drop tube 302 .

[0044] Since multiple drop tubes 302 are all located at the outer ring of the bottom of the material box 301, and are thus arranged at the center of the bottom of the material box 301 through the conical barrel 303, it is convenient for the raw materials to automatically slide down through the conical surface of the conical barrel 303 to the upper ports of the multiple drop tubes 302, thereby avoiding excessive storage of raw materials in the material box 301.

[0045] Further:

[0046] An upper transverse plate 304 is fixed to the lower end of the cone barrel 303, and a middle transverse plate is provided at the upper end of the inner pipe rack 201. Two sliding columns 203 are vertically fixed on the middle transverse plate. The two sliding columns 203 slide through the upper transverse plate 304, and a spring I 204 is provided between the upper transverse plate 304 and the middle transverse plate.

[0047] The sliding connection between the sliding column 203 and the upper cross plate 304 is ensured, thereby ensuring the synchronization between the middle cross plate and the upper cross plate 304, and then ensuring the synchronous rotation between the material box 301 and the inner pipe rack 201;

[0048] At the same time, through the setting of spring I 204, the elastic force of spring I 204 can push the inner tube rack 201 downward to drive multiple pressure rollers 202 to press the forming ring disk 101 downward, thereby increasing the pressure of the pressure rollers 202 to roll the raw material downward. Moreover, the reverse force of the raw material on the pressure rollers 202 can enable the pressure rollers 202 to drive the inner tube rack 201 to continue to compress the spring I 204 to move upward, thereby forming protection for the pressure rollers 202, and preventing the pressure rollers 202 from being damaged by hard contact with impurities in the raw material when they are retained on the forming ring disk 101.

[0049] Further:

[0050] A lower transverse plate 106 is fixed to the lower end of the inner hole of the forming ring disc 101 , a spline shaft 208 is rotatably mounted on the lower transverse plate 106 , a spline sleeve 207 is slidably mounted on the upper limit sleeve of the spline shaft 208 , and the spline sleeve 207 is fixed to the lower end of the inner pipe frame 201 .

[0051] The first motor installed on the lower horizontal plate 106 drives the spline shaft 208, thereby driving the inner pipe rack 201 to rotate through cooperation with the spline sleeve 207, and then the inner pipe rack 201 and the material box 301 rotate synchronously;

[0052] The spline shaft 208 and the spline sleeve 207 are slidably connected to each other, so that the pressure roller 202 is protected without affecting the up and down movement of the inner pipe frame 201 while maintaining the transmission between the two.

[0053] Further:

[0054] An adjusting screw 206 rotates at the center of the spline shaft 208 . The adjusting screw 206 passes through the inner pipe frame 201 and the cone barrel 303 and is threadedly connected to a threaded block 205 . The threaded block 205 is limited in sliding within a limit frame 306 provided inside the cone barrel 303 .

[0055] The lower end of the adjusting screw 206 is rotatably connected to the spline shaft 208 to form the installation of the adjusting screw 206, and then the thread forms a support for the horizontal position of the threaded block 205. Then, the weight of the material box 301 causes the upper end of the limit frame 306 to be pressed against the threaded block 205. Then, the threaded block 205 presses the upper end of the limit frame 306 in the limit frame 306, thereby forming support for the conical barrel 303.

[0056] By rotating the adjusting screw 206, the adjusting screw 206 and the threaded block 205 can be transmitted through the thread, and then the threaded block 205 can be moved axially on the adjusting screw 206, and then the conical barrel 303 can be lifted or lowered by the threaded block 205, thereby adjusting the gap between the lower end of the blanking pipe 302 and the upper end surface of the forming ring disk 101, and then adjusting the thickness of the flattened raw material;

[0057] It should be noted that, due to the weight of the material box 301, the threads between the threaded block 205 and the adjusting screw 206 are tightly fitted, and the friction between the two is relatively large, so that when the spline shaft 208 rotates, the adjusting screw 206 will not be driven to rotate.

[0058] Further:

[0059] A plurality of mounting plates 305 are fixed to the upper end of the material box 301 , and a transmission sleeve 401 is rotated on each mounting plate 305 near the center end of the material box 301 . A stirring shaft 402 slides inside the transmission sleeve 401 through a key, and a plurality of stirring plates 404 are provided on the stirring shaft 402 .

[0060] By rotating the transmission sleeve 401, the stirring shaft 402 is driven to rotate the multiple stirring plates 404 in the drop tube 302, thereby stirring the raw materials in the drop tube 302, improving the fluidity of the raw materials in the drop tube 302, and ensuring that the raw materials slide smoothly in the drop tube 302 to complete flattening.

[0061] Further:

[0062] A plurality of scrapers 403 are fixed to the lower end of the stirring shaft 402 . A spring II 405 is provided between the stirring shaft 402 and the corresponding transmission sleeve 401 to enable the plurality of scrapers 403 to press against the upper end surface of the forming ring disc 101 .

[0063] By setting up multiple scrapers 403, the upper end surface of the forming ring disk 101 can be scraped to prevent the raw material from being pressed and retained on the upper end surface of the forming ring disk 101, thereby affecting the pressure roller 202 from rolling the raw material into the forming hole 104. Among them, the setting of spring II 405 can ensure that the scraper 403 is in contact with the upper end surface of the forming ring disk 101 when the material box 301 is adjusted up and down by the adjusting screw 206.

[0064] Further:

[0065] Each mounting plate 305 is also provided with another rotating transmission sleeve 401 near the center end of the material box 301. A transmission shaft 407 is keyed and slidably mounted inside each transmission sleeve 401. A grooved wheel 406 is fixed to the lower end of each transmission shaft 407. Multiple grooved wheels 406 are transmission-connected to the gear ring on the ring frame 107. The two transmission sleeves 401 on the same mounting plate 305 are transmission-connected.

[0066] Therefore, when the material box 301 rotates, it can also drive the mounting plate 305 to rotate, so that the groove wheel 406 and the gear ring on the ring frame 107 move relative to each other and engage, thereby rotating the transmission shaft 407 and then driving the stirring shaft 402.

[0067] Further:

[0068] A conical bucket 108 is fixed between the two support plates 105 for receiving formed particles.

[0069] like Figure 1-9 As shown, the preparation method is described in detail:

[0070] The preparation method of the growth-promoting pig feed preparation device includes:

[0071] S1. The mixed powdered raw materials are heated and humidified with steam and then added into the material box 301;

[0072] S2, the material box 301 and the inner tube rack 201 rotate synchronously, so that the raw materials in the material box 301 are evenly spread in front of the multiple pressing rollers 202 through the multiple drop tubes 302;

[0073] S3, the rolling pressing roller 202 presses the raw material into the forming hole 104 for compression molding, and the raw material slides out of the lower end of the forming hole 104 in a columnar form and is blocked into particles after falling;

[0074] S4. The raw material is heated and expanded at the heating jacket in the forming hole 104.

[0075] Growth-promoting pig feed includes: 40%-50% corn, 20%-25% soybean meal, 5%-10% fish meal, 2%-3% vegetable oil, and 1%-2% vitamins and trace elements.
