Description

Technical Field

[0001] This utility model relates to the field of corn stalk processing technology, specifically to a corn stalk feed compression molding machine. Background Technology

[0002] Corn stalks, as a feed resource, have broad utilization value and promising development prospects. They can serve as a primary roughage for ruminants such as cattle and sheep, and their nutritional value and palatability can be improved through various processing techniques, thereby enhancing livestock profitability. Corn stalks are mainly composed of cellulose, hemicellulose, and lignin, and their nutritional value is relatively low, making them difficult for cattle and sheep to digest and absorb. Untreated corn stalks have low crude protein content and high cellulose content, resulting in low digestibility. However, through appropriate processing, their nutritional value can be significantly improved.

[0003] Pellet feed processing involves processing corn stalks through shredding, crushing, and conditioning, then pressing them into pellets using a pellet mill. Key steps include: drying, controlling the moisture content of the corn stalks to below 20%; crushing, ensuring the crushed length is less than 10 mm and the fineness is less than 2 mm; and pelleting, where the crushed stalks are fed into the pellet mill's storage hopper, and non-protein nitrogen and binders are added as needed, mixed evenly, and then pelleted.

[0004] The pelleting equipment mentioned above usually produces pellets of a fixed size, and the finished feed pellets are of a fixed size. However, when feeding livestock, the livestock have different growth cycles, and different sizes of feed pellets should be used for different growth cycles. For example, young livestock are prone to indigestion when fed large pellets, while adult livestock will take longer to eat when fed small pellets. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a corn stalk feed compression molding machine, which can effectively solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a corn stalk feed compression molding machine, including an outer shell. Support legs are fixed at the four corners of the bottom of the outer shell. A hydraulic rod is fixed to the top of the outer shell via a support rod. A compression plate is fixed to the power output end of the hydraulic rod. A first discharge port is opened through the bottom of the outer shell. A feed inlet is opened through the middle of one side of the outer wall of the outer shell. A movable plate is slidably connected to the bottom of the outer wall of the outer shell. A second discharge port is opened through the top of the movable plate. A threaded rod is rotatably connected to the middle of one side of the bottom of the outer wall of the outer shell. A servo motor is fixed to the bottom of the movable plate via a first connecting rod. A rotating shaft is fixed to the power output end of the servo motor. A cutting rod is fixed to the outer wall of the rotating shaft via bolts.

[0008] Furthermore, slide rods are fixed to both sides of the top of the movable plate via second connecting blocks, and guide rails are fixed to both sides of the bottom of the outer wall of the outer shell. The two guide rails are respectively movably connected to the two slide rods. A second connecting rod is fixed to one end of each slide rod. The second connecting rod is threadedly connected to a threaded rod. A knob is fixed to one end of the threaded rod.

[0009] Furthermore, there are multiple first discharge ports and multiple second discharge ports, with the multiple first discharge ports and multiple second discharge ports arranged in a one-to-one correspondence.

[0010] Furthermore, one side of the cutting rod is slit-shaped, the cutting rod is movably sleeved with the rotating shaft, and a bolt is threaded through one side of the cutting rod, the bolt being in contact with the rotating shaft.

[0011] Furthermore, a feed pipe and a first connecting block are fixed on the outer wall of the outer shell near the feed inlet. The first connecting block is located directly above the bottom end of the feed pipe. A miniature electric telescopic rod is fixed at the bottom of the first connecting block, and a baffle plate is fixed at the power output end of the miniature electric telescopic rod.

[0012] Furthermore, the baffle plate is used in conjunction with the feed inlet, and a control switch is fixed at the lower center of one side of the outer wall of the outer shell. The control switch is electrically connected to the miniature electric telescopic rod.

[0013] Furthermore, a collection box is slidably connected to the inner side of the four support legs, and the collection box is located directly below the bottom of the outer shell.

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0015] 1. This application uses a knob to rotate a threaded rod, which in turn moves a second connecting rod horizontally. The moving plate slides at the bottom of the outer shell, changing the overlap between the first discharge port at the bottom of the outer shell and the second discharge port at the bottom of the moving plate. The size of the overlap area is the fineness of the feed pellets after they are formed. The knob is rotated until the size of the overlap area meets the required fineness, thereby achieving the effect of adjusting the fineness of the finished feed pellets according to the maturity of the livestock to be fed.

[0016] 2. This application uses a servo motor to drive the rotating shaft to rotate, which in turn drives the cutting rod to rotate. The cutting rod cuts the feed particles squeezed out from the bottom of the moving plate to prevent excessively long particles. The length of the cut feed particles is controlled by adjusting the position of the cutting rod on the rotating shaft. After the position of the cutting rod is adjusted, it can be limited by bolts, thereby achieving the ability to adjust the length of the finished feed.

[0017] 3. This application allows for feeding by operating the control switch, controlling the coarseness by rotating the knob, and controlling the length of the feed by adjusting the position of the cutting rod and tightening the bolt to the limit, thus achieving a relatively convenient overall operation of the device.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0026] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0027] This application discloses a corn stalk feed compression molding machine, including an outer shell 1. Support legs 8 are fixed at the four corners of the bottom of the outer shell 1. A hydraulic rod 3 is fixed to the top of the outer shell 1 via a support rod 2. An extrusion plate 4 is fixed to the power output end of the hydraulic rod 3. A first discharge port 7 is opened through the bottom of the outer shell 1. A feed port 6 is opened through the middle of one side of the outer wall of the outer shell 1. A moving plate 17 is slidably connected to the bottom of the outer wall of the outer shell 1. A second discharge port 18 is opened through the top of the moving plate 17. A threaded rod 23 is rotatably connected to the middle of one side of the bottom of the outer wall of the outer shell 1. A servo motor 20 is fixed to the bottom of the moving plate 17 via a first connecting rod 19. A rotating shaft 201 is fixed to the power output end of the servo motor 20. A cutting rod 21 is fixed to the outer wall of the rotating shaft 201 by bolts.

[0028] Reference Appendix Figure 3 The top two sides of the movable plate 17 are fixed with slide rods 15 by the second connecting blocks 16. The bottom two sides of the outer wall of the outer shell 1 are fixed with guide rails 14. The two guide rails 14 are movably connected to the two slide rods 15 respectively. The two slide rods 15 are fixed with a second connecting rod 22 at one end. The second connecting rod 22 is threadedly connected to the threaded rod 23. The threaded rod 23 is fixed with a knob 24 at one end. By rotating the knob 24, the threaded rod 23 is rotated, which in turn drives the second connecting rod 22 to move in the horizontal direction, so that the movable plate 17 slides at the bottom of the outer shell 1. Through the cooperation of the guide rails 14 and the slide rods 15, the movement of the movable plate 17 is not affected, and the support of the movable plate 17 at the bottom of the outer shell 1 is increased.

[0029] Reference Appendix Figure 2 and 3 The first discharge port 7 is provided in multiple ways, and the second discharge port 18 is provided in multiple ways. The multiple first discharge ports 7 and the multiple second discharge ports 18 are arranged in a one-to-one correspondence. When the moving plate 17 moves, the overlapping position of the first discharge port 7 at the bottom of the outer shell 1 and the second discharge port 18 at the bottom of the moving plate 17 changes. The size of the overlapping area is the coarseness of the feed pellet after it is formed.

[0030] Reference Appendix Figure 3 The cutting rod 21 has a slit-like design on one side and is movably connected to the rotating shaft 201. A bolt is threaded through one side of the cutting rod 21 and is in contact with the rotating shaft 201. The rotating shaft 201 is rotated by the servo motor 20, which in turn drives the cutting rod 21 to rotate. The cutting rod 21 cuts the feed particles squeezed out from the bottom of the moving plate 17 to prevent excessively long particles. The length of the cut feed particles is controlled by adjusting the position of the cutting rod 21 on the rotating shaft 201. After the position of the cutting rod 21 is adjusted, it can be limited by the bolt.

[0031] Reference Appendix Figure 1 and 4 The outer wall of the outer shell 1 is fixed with a feed pipe 9 and a first connecting block 10 on the side near the feed inlet 6. The first connecting block 10 is located directly above the bottom of the feed pipe 9. A miniature electric telescopic rod 11 is fixed at the bottom of the first connecting block 10. A baffle plate 12 is fixed at the power output end of the miniature electric telescopic rod 11. The position of the baffle plate 12 is adjusted by the miniature electric telescopic rod 11 to control the discharge of the crushed corn stalk raw material inside the feed pipe 9.

[0032] Reference Appendix Figure 1 and 4 The baffle plate 12 is used in conjunction with the feed inlet 6. A control switch 13 is fixed at the lower middle part of one side of the outer wall of the outer shell 1. The control switch 13 is electrically connected to the micro electric telescopic rod 11. By operating the control switch 13, the micro electric telescopic rod 11 is controlled. When the micro electric telescopic rod 11 extends, the baffle plate 12 blocks the feed inlet 6 to prevent the raw material inside the feed pipe 9 from falling above the extrusion plate 4. After the raw material inside the outer shell 1 is extruded and granulated, and the hydraulic rod 3 retracts to lift the extrusion plate 4 upward, the micro electric telescopic rod 11 is then controlled to shorten, so that the raw material inside the feed pipe 9 can fall inside the outer shell 1 and be located below the extrusion plate 4. The four support legs 8 are slidably connected to the inner side of the collection box 25. The collection box 25 is located directly below the bottom of the outer shell 1. The collection box 25 collects the feed pellets extruded at the overlapping part of the first discharge port 7 at the bottom of the outer shell 1 and the second discharge port 18 at the bottom of the moving plate 17.

[0033] The workflow of this utility model is as follows:

[0034] First, adjust the size of the finished feed pellets according to the maturity level of the livestock to be fed. For example, young livestock need to use small pellets. By turning the knob 24, the threaded rod 23 is rotated, which in turn moves the second connecting rod 22 horizontally. The moving plate 17 slides at the bottom of the outer shell 1. Through the cooperation of the guide rail 14 and the sliding rod 15, the movement of the moving plate 17 is not affected, while increasing the support of the moving plate 17 at the bottom of the outer shell 1. The overlap position of the first discharge port 7 at the bottom of the outer shell 1 and the second discharge port 18 at the bottom of the moving plate 17 is changed. The size of the overlap area is the coarseness of the feed pellets after they are formed. Turn the knob 24 until the size of the overlap area meets the required coarseness. Then, adjust the position of the cutting rod 21 on the rotating shaft 201 to control the length of the cut feed pellets. After the position of the cutting rod 21 is adjusted, use bolts to limit it. During processing, the crushed feed pellets are cut into smaller pieces. Corn stalk raw material is conveyed to the feed pipe 9 via a conveyor belt. The micro electric telescopic rod 11 is controlled by the operation control switch 13. When the micro electric telescopic rod 11 extends, the baffle plate 12 blocks the feed port 6 to prevent the raw material inside the feed pipe 9 from falling above the extrusion plate 4. After the raw material is extruded and granulated inside the outer shell 1, and the hydraulic rod 3 retracts to lift the extrusion plate 4 upward, the micro electric telescopic rod 11 is then controlled to shorten, so that the raw material inside the feed pipe 9 can fall inside the outer shell 1 and be located below the extrusion plate 4. Then, the hydraulic rod 3 is controlled to drive the extrusion plate 4 downward to extrude the raw material from the first discharge port 7 and the second discharge port 18. At the same time, the servo motor 20 drives the rotating shaft 201 to rotate, which in turn drives the cutting rod 21 to rotate. The cutting rod 21 cuts the feed pellets extruded from the bottom of the moving plate 17 to prevent excessively long pellets. The collection box 25 collects the feed pellets extruded from the bottom of the outer shell 1.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
