Technical Field

[0001] This invention belongs to the field of raw material conveying technology, specifically relating to a suspended lifting device for raw materials used in the preparation of concentrated biological feed for pigs and its preparation process. Background Technology

[0002] The raw material suspension lifting device and preparation process for pig bioconcentrated feed are suitable for vertical or inclined conveying and lifting of various raw materials in the production process of pig bioconcentrated feed. It can be applied to feed processing enterprises, bio-feed production bases and feed workshops supporting large-scale farms.

[0003] Chinese patent CN120864140B, published on April 21, 2026, discloses a conveying auger for processing gluten powder. The auger includes a housing for conveying and a spiral blade driven by a motor inside the housing. The housing has an inlet and an outlet for feeding and discharging materials at its two ends.

[0004] In the aforementioned application document, after the conveying operation is completed, the collected powder is directionally conveyed to the discharge port through a dedicated pipeline to achieve seamless connection between conveying and cleaning. However, during the process of conveying raw materials for the preparation of incompletely dried pig bioconcentrated feed, some viscous raw materials adhere to the top of the conveying chamber as the spiral blades rotate, resulting in waste of raw materials and increasing the difficulty of subsequent cleaning of the device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a suspended lifting device for raw materials used in the preparation of concentrated biological feed for pigs, as well as a preparation process, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a suspended lifting device for raw materials used in the preparation of concentrated pig feed, comprising a conveying chamber and a suspension frame. The top and bottom of the conveying chamber are respectively equipped with an inlet pipe and a outlet pipe. Inside the conveying chamber is a power rod driven by a servo motor, and the outside of the power rod is equipped with helical blades. Inside the conveying chamber is a moving rod driven by a linear motor. A top scraper is fixedly connected to the side of the moving rod, and a cam is fixedly connected to the outside of the power rod. An extrusion plate is connected to the inner wall of the conveying chamber via a spring. A through-hole is formed on the extrusion plate near the inlet pipe. A force-bearing rod is fixedly connected to the bottom of the extrusion plate. An arc-shaped plate is connected to the bottom of the top scraper via a spring. The discharge pipe is equipped with a dredging component, and the top of the conveying bin is equipped with a recycling component. Through this device design, while the top scraper is scraping away viscous material from the top side of the conveying bin's inner wall, the extrusion plate intermittently applies additional pressure to the top scraper. This improves the scraper's effectiveness in removing material adhering to the top of the conveying bin, reduces material waste, and lowers the difficulty of subsequent cleaning.

By configuring the unblocking assembly, the telescopic rod rotates synchronously when its telescopic end reciprocates in the vertical direction, unblocking the raw material in the discharge pipe, preventing blockage, and further improving the conveying efficiency of the device.

[0010] As a further description of the above technical solution: The transmission rod passes through the fixed chamber, and the transmission rod is in a sliding connection with the fixed chamber.

[0011] As a further description of the above technical solution: One end of the transmission rod away from the extrusion plate is mounted on the telescopic end of the telescopic rod and is rotatably connected to the telescopic rod.

[0012] As a further description of the above technical solution: The end of the chain furthest from the first sprocket is fitted onto the outer side of the second sprocket.

[0013] As a further description of the above technical solution: The recycling assembly includes a connecting rod fixed to one side of the transmission rod, a pump body mounted on the top of the conveying chamber, connecting pipe one and connecting pipe two mounted on both sides of the pump body, a pump switch mounted on the side of the pump body, a through-hole fixing slot one on the top of the fixed chamber, and a through-hole fixing slot two on the side of the feed pipe. By configuring the recycling assembly, powdery raw materials scattered in the fixed chamber as the transmission rod moves can be fed back into the feed pipe, further reducing material waste.

S2: The mixed dry powder base material is fed into the auger mixing chamber, and the pre-activated probiotic liquid or compound enzyme preparation is precisely sprayed into the auger mixing chamber through a metering pump. S3: The wet material containing liquid is subjected to secondary forced mixing and kneading through the auger mixing chamber to ensure that live bacteria or enzymes are evenly attached to the surface of each particle, thus completing the key inoculation process of bio-concentrated feed. S4: Install a forming die head at the discharge port of the auger mixing chamber to use the mechanical pressure of the auger to squeeze the material into granules or strips; S5: The finished product is then transported via a suspended conveyor.

[0016] The advantages of this application are: (1) In this application, the raw material to be conveyed is fed into the conveying bin on the suspension frame through the feed pipe. The power rod and moving rod driven by the servo motor are activated. In conjunction with the cam, spring one, extrusion plate, force rod, spring two, arc plate and through groove, the extrusion plate intermittently applies additional pressure to the top scraper during the process of the top scraper scraping the viscous raw material on the top side of the inner wall of the conveying bin.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0022] Example 1, please refer to Figures 1-5 A suspended lifting device for preparing concentrated pig feed includes a conveying chamber 100 and a suspension frame 600. The top and bottom of the conveying chamber 100 are respectively equipped with an inlet pipe 200 and a discharge pipe 300. Inside the conveying chamber 100 is a power rod 400 driven by a servo motor, and the outside of the power rod 400 is equipped with spiral blades 500. The raw material to be conveyed is fed into the conveying chamber 100 on the suspension frame 600 through the inlet pipe 200. Activating the power rod 400 driven by the servo motor causes the fixedly connected spiral blades 500 to rotate, thus lifting and conveying the raw material within the conveying chamber 100.

[0023] The conveying chamber 100 is equipped with a moving rod 701 driven by a linear motor, and a top scraper 702 is fixedly connected to the side of the moving rod 701. When the moving rod 701 driven by the linear motor is activated, the moving rod 701 drives the top scraper 702 fixedly connected to it to reciprocate in the horizontal direction, scraping off the viscous material on the top side of the inner wall of the conveying chamber 100.

[0024] A cam 703 is fixedly connected to the outer side of the power rod 400. When the power rod 400 rotates, it drives the cam 703, which is fixedly connected to it, to rotate synchronously.

[0025] The inner wall of the conveying chamber 100 is connected to an extrusion plate 705 via a spring 704. A through-hole 709 is provided on the extrusion plate 705 near the feed pipe 200. A force-bearing rod 706 is fixedly connected to the bottom of the extrusion plate 705, located at the top of the cam 703, and in contact with the cam 703. When the protruding part of the cam 703 rotates to the force-bearing rod 706, it compresses the force-bearing rod 706. The compressed force-bearing rod 706 then moves the extrusion plate 705 upwards, compressing the spring 704.

[0026] When the protruding part of the cam 703 rotates away from the force rod 706, the force rod 706 and the pressing plate 705 lose their restraint and can be reset under the action of the spring 704. In this way, the pressing plate 705 can reciprocate a certain distance in the vertical direction.

[0027] The bottom of the top scraper 702 is connected to an arc-shaped plate 708 via a spring 707. The arc-shaped plate 708 is located at the top of the extrusion plate 705, and the arc-shaped plate 708 is in contact with the extrusion plate 705. When the extrusion plate 705 moves upward, it can squeeze the arc-shaped plate 708 in contact with it. The compressed arc-shaped plate 708 can then apply additional pressure to the top scraper 702 via the spring 707. The extrusion plate 705, in its reciprocating motion, can intermittently apply additional pressure to the top scraper 702. This improves the processing effect of the top scraper 702 on raw materials adhering to the top of the conveying bin 100, reduces material waste, and lowers the difficulty of subsequent cleaning of the device.

[0028] In practical use, the raw material to be conveyed is fed into the conveying bin 100 on the suspension frame 600 through the feed pipe 200. The power rod 400, driven by a servo motor, is activated, causing the spiral blade 500 fixedly connected to it to rotate, thus lifting and conveying the raw material in the conveying bin 100. Simultaneously, the moving rod 701, driven by a linear motor, is activated, causing the top scraper 702 fixedly connected to it to reciprocate horizontally, scraping away viscous material from the top side of the inner wall of the conveying bin 100. The rotating power rod 400 drives the cam 703 fixedly connected to it to rotate synchronously. When the protruding part of the cam 703 rotates to the force rod 706, it squeezes the force rod 706, causing it to be squeezed. The pressing force rod 706 can drive the pressing plate 705, which is fixedly connected to it, to move upward. At this time, the pressing plate 705 compresses the spring 704 and moves upward. As the cam 703 continues to rotate, when its protruding part moves away from the force rod 706, the force rod 706 and the pressing plate 705 lose their restraint and can be reset under the action of the spring 704. In this way, the pressing plate 705 can reciprocate a certain distance in the vertical direction. When the pressing plate 705 moves upward, it can press the arc plate 708 that is in contact with it. The arc plate 708, which is pressed, can apply additional pressure to the top scraper 702 through the spring 707. The pressing plate 705, which is in the reciprocating state, can intermittently apply additional pressure to the top scraper 702.

[0029] Example 2, please refer to Figures 4-7 Based on Embodiment 1, a clearing component 800 is installed inside the discharge pipe 300. The clearing component 800 includes a transmission rod 801 fixed to the side of the extrusion plate 705. A fixed chamber 810 is installed on the side of the conveying chamber 100. The transmission rod 801 passes through the fixed chamber 810 and is slidably connected to the fixed chamber 810. A telescopic rod 802 is rotatably connected inside the discharge pipe 300. The end of the transmission rod 801 away from the extrusion plate 705 is mounted on the telescopic end of the telescopic rod 802 and is rotatably connected to the telescopic rod 802. The extrusion plate 705, which reciprocates vertically, can drive the transmission rod 801, which is fixedly connected to it, to reciprocate vertically as well, so that the transmission rod 801 drives the telescopic end of the telescopic rod 802, which is rotatably connected to it, to reciprocate vertically as well.

[0030] A transmission rod 2 803 is fixedly connected to the side of the power rod 400, and a bevel gear 1 804 is fixedly connected to the side of the transmission rod 2 803. When the power rod 400 rotates, it drives the transmission rod 2 803 fixedly connected to it to rotate, which in turn drives the bevel gear 1 804 fixedly connected to it to rotate.

[0031] The fixed chamber 810 has a through-type transmission rod 805 rotatably connected inside. A bevel gear 806 and a sprocket 807 are fixedly connected to the outer side of the transmission rod 805. The bevel gear 806 meshes with the bevel gear 804. When the bevel gear 804 rotates, it drives the bevel gear 806 to rotate, which in turn drives the transmission rod 805 to rotate. The rotating transmission rod 805 then drives the sprocket 807 to rotate.

[0032] A chain 808 is mounted on the outer side of sprocket 1 807. A sprocket 2 809 is fixedly connected to the outer side of the fixed end of telescopic rod 802. The end of chain 808 away from sprocket 1 807 is mounted on the outer side of sprocket 2 809. When sprocket 1 807 rotates, it works in conjunction with the chain 808 mounted on the outer side of sprocket 1 807 to cause sprocket 2 809, which is connected to sprocket 1 807 via chain 808, to rotate synchronously. The rotating sprocket 2 809 can then drive the fixed end of telescopic rod 802, which is fixedly connected to it, to rotate. In this way, the telescopic end of the telescopic rod 802 can rotate synchronously when it moves back and forth in the vertical direction, clearing the raw material in the discharge pipe 300, preventing the discharge pipe 300 from getting blocked, and further improving the conveying efficiency of the device.

[0033] In practical use, the extrusion plate 705, which reciprocates vertically, drives the transmission rod 801, which is fixedly connected to it, to reciprocate vertically as well. This causes the transmission rod 801 to drive the telescopic end of the telescopic rod 802, which is rotatably connected to it, to reciprocate vertically as well. The rotating power rod 400 drives the transmission rod 803, which is fixedly connected to it, to rotate. This causes the transmission rod 803 to drive the bevel gear 804, which is fixedly connected to it, to rotate. The rotating bevel gear 804 then drives the bevel gear 806, which meshes with it, to rotate. The second bevel gear 806 drives the third transmission rod 805, which is fixedly connected to it, to rotate. The rotating transmission rod 805 drives the first sprocket 807, which is fixedly connected to it, to rotate. In conjunction with the chain 808 mounted on the outside of the first sprocket 807, the second sprocket 809, which is connected to the first sprocket 807 via the chain 808, rotates synchronously. The rotating sprocket 809 drives the fixed end of the telescopic rod 802, which is fixedly connected to it, to rotate. In this way, the telescopic end of the telescopic rod 802 rotates synchronously when it reciprocates in the vertical direction, thus clearing the raw material in the discharge pipe 300.

[0034] Example 3, please refer to Figures 6-9Based on Embodiment 1, a recovery assembly 900 is mounted on the top of the conveying chamber 100. The recovery assembly 900 includes a connecting rod 901 fixed to the side of the transmission rod 801. When the transmission rod 801 reciprocates a certain distance in the vertical direction, it can drive the connecting rod 901 fixedly connected to it to reciprocate a certain distance in the vertical direction as well.

[0035] The top of the conveying chamber 100 is equipped with a pump body 902. Connecting pipe 1 903 and connecting pipe 2 904 are respectively installed on both sides of the pump body 902. A pump switch 905 is installed on the side of the pump body 902. When the connecting rod 1 901 presses the pump switch 905 during movement, the pump body 902 can be activated.

[0036] The top of the fixed chamber 810 has a through-hole fixed groove 906, the cross-sectional shape of which is adapted to the cross-sectional shape of the connecting pipe 903. When the extraction pump body 902 is activated, the powdery raw materials that may be scattered in the fixed chamber 810 as the transmission rod 801 moves can be extracted into the connecting pipe 903 through the connecting pipe 903, which is mounted on the side of the extraction pump body 902 and connects the extraction pump body 902 and the fixed chamber 810, and the fixed groove 906 on the fixed chamber 810.

[0037] A through-hole fixing groove 907 is provided on the side of the feed pipe 200. The cross-sectional shape of the fixing groove 907 is adapted to the cross-sectional shape of the connecting pipe 904. After the raw material is drawn into the connecting pipe 903, the raw material can be fed back into the feed pipe 200 through the fixing groove 907 on the feed pipe 200 by the extraction pump body 902 and the connecting pipe 904, further reducing the waste of raw materials.

[0038] In practical use, when the transmission rod 801 moves back and forth a certain distance in the vertical direction, it can drive the connecting rod 901, which is fixedly connected to it, to move back and forth a certain distance in the vertical direction as well. When the connecting rod 901 squeezes the extraction pump switch 905 during the movement, the extraction pump body 902 can be activated. As the extraction pump body 902 is activated, the powdery raw materials that may be scattered in the fixed chamber 810 as the transmission rod 801 moves can be extracted into the connecting pipe 903 through the connecting pipe 903 assembled on the side of the extraction pump body 902 and connecting the extraction pump body 902 and the fixed chamber 810, and the fixed groove 906 opened on the fixed chamber 810. Then, through the extraction pump body 902 and the connecting pipe 904, the powdery raw materials are sent back into the feed pipe 200 through the fixed groove 907 opened on the feed pipe 200.

[0039] A process for preparing a concentrated biological feed for pigs includes the following steps: S1: First, the bulk dry powder raw materials such as soybean meal, corn gluten powder, and premix, which are weighed according to the formula, are sent into the mixing chamber by the elevator for preliminary mixing. S2: The mixed dry powder base material is fed into the auger mixing chamber, and the pre-activated probiotic liquid or compound enzyme preparation is precisely sprayed into the auger mixing chamber through a metering pump.
