[0002] my country has a large population and scarce resources, and the development and utilization of corn stalks is still in its early stages. Corn stalk processing machinery is relatively simple and crude, only allowing for the laying of whole stalks. Given the current shortage of forage in the livestock industry, solving the problem of corn stalk forage production is essential. It is proposed to develop and manufacture a corn ear-picking and stalk baling combine harvester to make corn harvesting, stalk forage production, and baling fully mechanized.
[0003] In the current technology, workers put the straw into the crusher, and the straw is crushed by the rotation of the crushing blades, which makes it convenient for subsequent processing.
[0004] However, in actual use, due to the long length of the straw, when the whole straw is put into the crusher, it is easy for the straw to get tangled on the rotating rod of the crushing blade, which can even damage the crushing blade and increase costs. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a corn stalk forage conversion device, which solves the problem that in actual use, due to the long length of the stalks, when the entire stalk is put into the crusher, the stalks easily become entangled on the rotating rod of the crushing blade, which can even damage the crushing blade and increase costs.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a corn stalk forage conversion device, comprising a cutting box, a crushing box connected to the bottom of the cutting box, a discharge port connected to the bottom of the crushing box, a feeding plate connected to the upper part of the outer wall of the cutting box, a limiting plate installed inside the cutting box, a cutter positioned above the limiting plate, a support plate sleeved on the outer wall of the cutter, a mounting plate fixedly connected to one end of the cutter that penetrates the support plate, the outer wall of the mounting plate being movably connected to the inner wall of the cutting box, and a reciprocating structure installed on the top of the mounting plate.
[0007] Preferably, the reciprocating structure includes a connecting rod, a turntable, a fixed housing, and a second servo motor.

[0011] Beneficial effects
[0012] This utility model provides a corn stalk forage conversion device. It has the following beneficial effects: Through the cooperation of a connecting rod, a turntable, and a cutter, when whole stalks are fed into the cutting box, a second servo motor drives the turntable to rotate, which in turn drives the connecting rod to move up and down. This causes the mounting plate to drive the cutter to cut the stalks in the cutting box, thus facilitating subsequent shredding. This solves the problem that when whole stalks are placed inside the shredder, they easily become entangled on the rotating rod of the shredder blade, which can even damage the blade and increase costs.
[0013] By combining the crushing blades, rotating rod, and fixing frame, a double row of crushing blades is set inside the crushing box, and the crushing blades and rotating rod are placed vertically. In this way, when the cut straw falls into the crushing box, it can be fully crushed, ensuring that the straw is crushed more thoroughly, thus solving the problem of insufficient crushing of straw by single crushing in the existing technology.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] In actual use, because the straw is quite long, when the whole straw is put into the crusher, it is easy for the straw to get tangled on the rotating rod of the crushing blade. In severe cases, it can even damage the crushing blade, leading to increased costs.
[0021] In view of this, the present invention provides a corn stalk forage device, which solves the problem that in actual use, due to the long length of the stalk, when the whole stalk is put into the crusher, the stalk is easily wrapped around the rotating rod of the crushing blade, which may even damage the crushing blade and increase costs.
[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0023] Example 1: By Figure 1-4 It is known that the corn stalk forage device includes a cutting box 1, a crushing box 2 connected to the bottom of the cutting box 1, a discharge port 3 connected to the bottom of the crushing box 2, a feeding plate 4 connected to the upper part of the outer wall of the cutting box 1, a limiting plate 10 installed inside the cutting box 1, a cutter 9 set above the limiting plate 10, a support plate 21 sleeved on the outer wall of the cutter 9, an installation plate 8 fixedly connected to one end of the cutter 9 that passes through the support plate 21, the outer wall of the installation plate 8 is movably connected to the inner wall of the cutting box 1, and a reciprocating structure is installed on the top of the installation plate 8;
[0024] In the specific implementation process, it is worth noting that the length of the cutting box 1 can meet the length of the straw itself. When the straw enters the cutting box 1, it can be cut into segments. The feeding plate 4 facilitates the entry of the straw into the cutting box 1. The cut straw will fall into the crushing box 2 for crushing. The crushed straw will be discharged through the discharge port 3 at the bottom. The limiting plate 10 facilitates the cutting of the straw by the cutter 9. At the same time, the number of cutters 9 will be set according to the length of the straw to be cut, and the cutting 9 will be supported by the mounting plate 8 to make the straw stable during cutting.
[0025] Furthermore, the reciprocating structure includes a connecting rod 20, a turntable 6, a fixed housing 5, and a second servo motor 15. The connecting rod 20 is rotatably connected to the top of the mounting plate 8 via a pin. One end of the connecting rod 20 that passes through the cutting box 1 is rotatably connected to the turntable 6 via a pin. The outer wall of the turntable 6 is rotatably connected to the fixed housing 5 via a sealed bearing. The bottom of the fixed housing 5 is fixedly connected to the top of the cutting box 1. The end of the turntable 6 that extends to the outside of the fixed housing 5 is fixedly connected to the second servo motor 15. The outer wall of the second servo motor 15 is fixedly connected to the outer wall of the fixed housing 5.
[0026] In the specific implementation process, it is worth noting that the fixed shell 5 is used to support the turntable 6, and the outer wall of the turntable 6 is rotatably connected to the top of the connecting rod 20 through a pin, while its bottom is rotatably connected to the top of the mounting plate 8 through a pin. In this way, when the turntable 6 rotates, it will drive the connecting rod 20 to rise and fall around the position where the turntable 6 is rotatably connected to the fixed shell 5, and cause the mounting plate 8 to drive the cutter 9 to cut the straw in the cutting box 1. The model of the second servo motor 15 is not limited, as long as it meets the actual use. It is powered by an external power supply and can be connected to an external controller to control the rotation speed of the second servo motor 15, so that the cutter 9 can cut the straw conveniently.
[0027] Furthermore, limit posts 7 are fixedly connected to both sides of the top of the mounting plate 8, and the outer walls of the two limit posts 7 are inserted into the inner wall of the cutting box 1.
[0028] In the specific implementation process, it is worth noting that when the mounting plate 8 is raised and lowered, it will drive the limiting post 7 to move inside the cutting box 1, thereby stabilizing the mounting plate 8 during the raising and lowering process and ensuring that each cutter 9 exerts the same force on the straw, thus avoiding deviation during the cutting of straw and affecting the cutting effect.
[0029] Specifically, when using this corn stalk forage device, when crushing the stalks, the whole stalks are fed into the cutting box 1 through the feed plate 4, and the turntable 6 is driven to rotate by the second servo motor 15. When the turntable 6 rotates, the connecting rod 20 drives the mounting plate 8 and the cutter 9 to move up and down, thereby cutting the stalks in the cutting box 1. The cut stalks will fall into the crushing box 2, and after crushing, they will be discharged through the discharge port 3 at the bottom of the crushing box 2.
[0030] Example 2: From Figure 1-4 It can be seen that a crushing blade 12 is installed inside the crushing box 2. A rotating rod 13 is fixedly connected to the inner wall of the crushing blade 12. The top and bottom of the rotating rod 13 are rotatably connected to a fixed frame 11 through a sealed bearing. The outer walls of the two fixed frames 11 are fixedly connected to the inner wall of the crushing box 2. A linkage structure is installed at one end of the rotating rod 13 extending to the bottom of the fixed frame 11.
[0031] In the specific implementation process, it is worth noting that several crushing blades 12 are provided on the outer wall of the rotating rod 13, and the crushing blades 12 are arranged in two rows and placed vertically. With the support of the mounting plate 8, the two rows of crushing blades 12 can easily crush the straw. When the two rows of crushing blades 12 rotate alternately, the crushing blades 12 on both sides mesh together, so that the straw is fully crushed.
[0032] Furthermore, the linkage structure includes a first servo motor 14, a drive rod 16, a drive gear 17, a driven gear 18, and a protective shell 19. The outer wall of the first servo motor 14 is fixedly connected to the outer wall of the crushing box 2. The output end of the first servo motor 14 is fixedly connected to the drive rod 16 through a sealed bearing at one end of the crushing box 2. The outer wall of the drive rod 16 is rotatably connected to the protective shell 19 via a sealed bearing. The top of the protective shell 19 is fixedly connected to the bottom of the fixing frame 11. The drive rod 16 extends into the inside of the protective shell 19 and is fixedly connected to the drive gear 17. The outer wall of the drive gear 17 is meshed with the driven gear 18. The top of the driven gear 18 is fixedly connected to the bottom of the rotating rod 13. It is worth noting that the fixing frame 11 is a long strip plate. During installation, it will be fixed in the middle position of the crushing box 2. The cut straw will fall from both sides of the fixing frame 11 into the crushing box 2, which can avoid affecting the crushing of the straw.
[0033] In the specific implementation process, it is worth noting that both the driving gear 17 and the driven gear 18 are bevel gears, which can mesh together perfectly. When driving the crushing blades 12 on both sides to rotate, the first servo motor 14 drives the drive rod 16 to rotate. When the drive rod 16 drives the driving gear 17 to rotate, the meshing of the driving gear 17 and the driven gear 18 will cause the crushing blades 12 on both sides to rotate synchronously and mesh together, making it easier to crush the cut straw and ensuring that the straw is crushed more thoroughly. The model of the first servo motor 14 is not limited, as long as it meets the actual use. The protective shell 19 can cover the driving gear 17 and the driven gear 18 to prevent them from being affected during crushing.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
