Description

Technical Field

[0001] This invention relates to the field of animal manure recycling technology, and in particular to a cow manure briquetting mechanism. Background Technology

[0002] In large-scale cattle farming areas such as ranches, a large amount of cow dung is produced. Cow dung has fuel value, so it can be compacted into dung blocks for storage. In existing technology, patent CN219096024U discloses a cow dung briquetting device. This patent uses multiple pressure heads simultaneously entering a cow dung trough to compress the dung, transferring the resulting dung blocks to a pallet, which then outputs the dung blocks. This structure requires significant movement from both the pressure heads and the pallet, resulting in a large structure volume. Existing technology also uses honeycomb briquette forming equipment to compress cow dung into porous cylindrical shapes. For example, patent CN112210410B discloses a typical honeycomb briquette making device. This device includes a rotating mechanism and a pressing mechanism. The rotating mechanism's turntable has multiple forming holes. The turntable rotates to collect material from a feeding trough, while the pressing mechanism compresses the material in one forming hole while simultaneously pushing the finished product from another forming hole onto a conveyor belt. This solution also suffers from a large structure volume, and the pushing of the finished product can cause it to crack. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides a compact and small cow dung briquetting mechanism.

[0004] Technical solution: To achieve the above objectives, the cow dung briquetting mechanism of the present invention includes a turntable that can actively rotate relative to the base, the turntable having multiple forming cavities; the rotating shaft of the turntable is arranged horizontally, and the forming cavities are formed on its outer circumferential surface; each forming cavity is equipped with an extrusion plate and a rod, the extrusion plate being able to slide relative to the forming cavity;

[0005] The cow dung briquetting mechanism also includes a guide rail, a retaining plate, and a discharge mechanism; the guide rail is a circular structure, which is fixedly installed and eccentrically installed relative to the turntable; the guide rail can act on the extrusion plate to make the extrusion plate slide relative to the forming cavity.

[0006] The retaining plate has an arc-shaped structure and is attached to the outer circumferential surface of the forming cavity; the upper end of the retaining plate has a cow dung inlet;

[0007] The unloading mechanism is located at the bottom of the turntable.

[0008] Furthermore, a push rod is fixed to the extrusion plate, and a roller is rotatably mounted on the end of the push rod; the guide rail has an annular groove, which is offset relative to the rotation center of the turntable, and the roller is placed in the annular groove and can roll within the annular groove. The uppermost side of the annular groove is closest to the center of the turntable, and the lowermost side of the annular groove is farthest from the center of the turntable.

[0009] Furthermore, the end of the push rod is fixed with a discharge pull rod, the lower end of the annular groove has a notch, and the roller can move from the position of the notch to outside the annular groove; the discharge mechanism includes a support plate located below the turntable, the support plate can move up and down relative to the machine base, and a traction block is fixed on the support plate, the traction block has an arc-shaped groove for the discharge pull rod to enter and exit.

[0010] Furthermore, two guide rods are fixed on the base, and a guide sleeve is fixed on the pallet, with the guide sleeve slidingly engaging with the guide rods; a linear motion actuator, which pushes the pallet to move up and down, is installed on the base, and the linear motion actuator is an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder.

[0011] Furthermore, the turntable is mounted on the machine base via a crossed roller bearing. The crossed roller bearing has an external gear ring with a gear portion and is fixed on the turntable. A pinion is mounted on the machine base, and the pinion meshes with the external gear ring. The pinion is driven by a motor.

[0012] Using the above structure, the motor drives the turntable to rotate unidirectionally through a pinion and an external gear ring. The forming cavity passes sequentially through the cow dung inlet and the unloading mechanism. At the cow dung inlet, the forming cavity temporarily collects cow dung fragments. Then, the turntable closes the opening of the forming cavity with a retaining plate. Because the guide rail is eccentrically mounted relative to the turntable, the rollers, as they roll along the annular groove, push the extrusion plate to slide within the forming cavity, compacting the cow dung. When the rollers reach the lower side of the annular groove, the turntable stops moving, the cow dung is completely extruded, and at this position, the unloading pull rod is embedded in the arc-shaped groove of the pulling block, and the lower end of the forming cavity disengages from the retaining plate. The plate and support plate are located below the opening of the forming cavity. At this time, the linear motion actuator pushes the support plate down, and the support plate pulls the extrusion plate down synchronously through the traction block and the unloading rod (at this time, the roller leaves the annular groove from the notch at the lower end of the annular groove). The extrusion plate squeezes the formed cow dung block out of the forming cavity, and the support plate supports the cow dung block from below and lowers synchronously. In this way, the cow dung block will not fall and break after being extruded, which can ensure the integrity of the cow dung block. After the cow dung block is completely extruded, the external material handling mechanism removes the cow dung block, and the linear motion actuator makes the support plate rise. In this way, the motor continues to drive the turntable to rotate, which can make the forming cavity leave the unloading mechanism.

[0013] In the above process, while one of the forming chambers is located at the cow dung inlet for material intake, another forming chamber is located at the unloading mechanism for unloading cow dung blocks. In this way, the loading and unloading of cow dung blocks can be carried out simultaneously.

[0014] Furthermore, the turntable has an annular structure, comprising a thin-walled cylindrical intermediate body and two annular plates located on both sides of the intermediate body. The turntable has a U-shaped cross-section. The forming cavity is formed within a cylinder fixed relative to the intermediate body, and the rod is fixed relative to the bottom of the cylinder. A through hole is formed on the intermediate body corresponding to the portion of the cylinder. A clearance hole is formed on the extrusion plate corresponding to the position of the forming cavity. A guide rail is installed within the hollow space of the turntable. This structure ensures the strength of the turntable while making it lightweight and fully utilizing the hollow space within the turntable.

[0015] Furthermore, there are multiple rods, and all rods are arranged in a circumferential array on multiple circles.

[0016] Beneficial Effects: The cow dung briquetting mechanism of the present invention, by placing the turntable vertically with its axis of rotation horizontal and arranging the forming cavity on the outer circumference of the turntable, and by arranging the extrusion mechanism within the space of the turntable, can achieve the extrusion and shaping of cow dung during the transfer of cow dung material and the adjustment of its posture. Combined with the synergistic effect of the unloading mechanism, smooth unloading can be achieved. The compaction and unloading processes of cow dung are both carried out by the extrusion plate, which can save the number of parts, and the entire compaction and unloading process is completed in one go and runs smoothly. Compared with traditional cow dung compactors and honeycomb briquetting machines, the cow dung briquetting mechanism of the present invention has a compact and small structure and a significantly reduced weight.

Detailed Implementation

[0024] The invention will now be further described with reference to the accompanying drawings.

[0025] like Figure 1-4 The cow dung briquetting mechanism shown includes a turntable 1 that can actively rotate relative to a base 10, and the turntable 1 has multiple forming cavities 11. The rotating shaft of the turntable 1 is horizontally arranged, and the forming cavities 11 are formed on its outer circumference. Each forming cavity 11 is equipped with an extrusion plate 2 and a rod 3, and the extrusion plate 2 can slide relative to the forming cavity 11. The cow dung briquetting mechanism also includes a guide rail 4, a retaining plate 5, and a discharge mechanism 6. The guide rail 4 is a circular structure, which is fixedly installed and eccentrically installed relative to the turntable 1. The guide rail 4 can act on the extrusion plate 2 to make the extrusion plate 2 slide relative to the forming cavity 11. The retaining plate 5 is an arc-shaped structure that abuts against the outer circumference of the forming cavity 11. The upper end of the retaining plate 5 has a cow dung inlet 51. The discharge mechanism 6 is located at the bottom end of the turntable 1.

[0026] A push rod 21 is fixed on the extrusion plate 2, and a roller 22 is rotatably mounted on the end of the push rod 21. The guide rail 4 has an annular groove 41, which is offset relative to the rotation center of the turntable 1. The roller 22 is placed in the annular groove 41 and can roll within it. The uppermost side of the annular groove 41 is closest to the center of the turntable 1, and the lowermost side is farthest from the center of the turntable 1.

[0027] The end of the push rod 21 is fixed with a discharge pull rod 23. The lower end of the annular groove 41 has a notch, and the roller 22 can move from the position of the notch to outside the annular groove 41. The discharge mechanism 6 includes a support plate 61 located below the turntable 1. The support plate 61 can move up and down relative to the machine base 10. A pulling block 62 is fixed on the support plate 61. The pulling block 62 has an arc-shaped groove 62a for the discharge pull rod 23 to enter and exit.

[0028] Two guide rods 7 are fixed on the base 10, and a guide sleeve 63 is fixed on the pallet 61. The guide sleeve 63 is slidably engaged with the guide rods 7. A linear motion actuator 8 is installed on the base 10 to push the pallet 61 to move up and down. The linear motion actuator 8 is an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder.

[0029] The turntable 1 is mounted on the base 10 via a cross roller bearing 91. The cross roller bearing 91 has an external gear ring with a gear portion and is fixed on the turntable 1. A pinion 92 is mounted on the base 10, and the pinion 92 meshes with the external gear ring. The pinion 92 is driven by a motor 93.

[0030] Using the above structure, the motor 93 drives the turntable 1 to rotate unidirectionally through the pinion 92 and the external gear ring. The forming cavity 11 passes sequentially through the cow dung inlet 51 and the unloading mechanism 6. The forming cavity 11 temporarily collects cow dung fragments at the cow dung inlet 51, and then the turntable 1 closes the opening of the forming cavity 11 with the retaining plate 5. Because the guide rail 4 is eccentrically installed relative to the turntable 1, the roller 22 pushes the extrusion plate 2 to slide in the forming cavity 11 to compact the cow dung in the forming cavity 11 as it rolls along the annular groove 41. When the roller 22 moves to the lower side of the annular groove 41, the turntable 1 stops moving, and the cow dung is completely extruded and formed. At this position, the unloading pull rod 23 is embedded in the arc-shaped groove 62a of the pulling block 62, and the lower end of the forming cavity 11... After disengaging from the retaining plate 5, the support plate 61 is positioned below the opening of the forming cavity 11. At this time, the linear motion actuator 8 pushes the support plate 61 downward. Simultaneously, the support plate 61 pulls the extrusion plate 2 downward through the traction block 62 and the unloading pull rod 23 (at this time, the roller 22 leaves the annular groove 41 from the notch at the lower end of the annular groove 41). The extrusion plate 2 squeezes the formed cow dung block out of the forming cavity 11, and the support plate 61 supports the cow dung block from below and lowers it simultaneously. In this way, the cow dung block will not fall and break after being extruded, which can ensure the integrity of the cow dung block. After the cow dung block is completely extruded, the external material handling mechanism removes the cow dung block, and the linear motion actuator 8 causes the support plate 61 to rise. In this way, the motor 93 continues to drive the turntable 1 to rotate, which can make the forming cavity 11 leave the unloading mechanism 6.

[0031] During the process described above, while one of the forming chambers 11 is located at the cow dung inlet 51 for material intake, another forming chamber 11 is located at the unloading mechanism 6 for unloading cow dung blocks. This allows for the simultaneous loading of cow dung and the unloading of compacted cow dung blocks.

[0032] In this invention, by placing the turntable 1 vertically with its axis of rotation horizontal, and positioning the forming cavity 11 on the outer circumference of the turntable 1, and by arranging the extrusion mechanism within the space of the turntable 1, the cow dung can be extruded and its orientation adjusted during transport. Combined with the synergistic effect of the unloading mechanism 6, smooth unloading can be achieved. The compaction and unloading processes of the cow dung are both carried out by the extrusion plate 2, which saves on the number of parts, and the entire compaction and unloading process is completed smoothly in one go. Compared with traditional cow dung compactors and honeycomb briquette forming machines, the cow dung briquetting mechanism of this invention has a compact and small structure with significantly reduced weight.

[0033] The turntable 1 has an annular structure, comprising a thin-walled cylindrical intermediate body and two annular plates located on both sides of the intermediate body. The turntable 1 has a U-shaped cross-section. The forming cavity 11 is formed inside a cylinder 12 fixed relative to the intermediate body, and the rod 3 is fixed relative to the bottom of the cylinder 12. A through hole is formed on the intermediate body corresponding to the portion of the cylinder 12. A clearance hole is formed on the extrusion plate 2 corresponding to the position of the forming cavity 11. A guide rail 4 is installed in the hollow space inside the turntable 1. Using this structure, the turntable 1 can be made lightweight while maintaining its strength, and the hollow space inside the turntable 1 can be fully utilized.

[0034] The number of rods 3 is multiple, and all rods 3 are arranged in a circumferential array on multiple circles. By setting the rods 3, multiple honeycomb holes can be left on the cow dung block during the cow dung forming process, making the cow dung easy to burn.

[0035] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
