Description

Technical Field

[0001] The invention relates to the technical field of straw processing, in particular to a continuous feeding mechanism used for straw crushing processing. Background Art

[0002] After the harvest of crops and grains, the straw is first cut off by a sickle and then piled into bundles. It is then crushed in the crusher. Finally, the crushed straw is returned to the farmland as fertilizer to increase the organic fertilizer in the soil and improve the soil. With the household use, miniaturization and safety of crushers, the feeding method of crushers is also gradually changing. Especially in the process of straw crushing, the feeding method has an important impact on the efficiency and quality of straw crushing.

[0003] According to the automatic feeding device of a straw crusher with publication number CN206923333U, the main shaft designed at the feeding port can provide a feeding function, so that the straw can enter the twisting cage in an orderly manner for crushing, and there will be no problems such as entanglement and knotting, thereby improving the crushing efficiency of the straw crusher;

[0004] However, the above equipment only realizes a simple feeding function. During actual operation, it still needs to rely on traditional hand-pushing to load the materials. It is difficult to control the amount of straw material introduced at a single time, and it is easy for the feeding amount of a single material to be more or less, as well as the defect of discontinuous feeding. In addition, when the straw material is harvested and stacked, the straw bundles are prone to become disordered and fluffy, causing blockage of the feeding port and affecting the crushing rate during the subsequent feeding process.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figure 1 - Figure 7 As shown, a continuous feeding mechanism used for straw crushing processing comprises a feeding frame 1, a long feeding frame 2, a guide plate 3 and a transfer plate 4 of a rectangular structure, wherein the long feeding frame 2 is arranged at one side of the top surface of the feeding frame 1, the guide plate 3 is of an inclined structure and is arranged at the middle section of the inner wall of one side of the feeding frame 1, and the bottom of the long feeding frame 2 extends above the guide plate 3, and the top surface of the guide plate 3 is provided with slide grooves 301 at the front, middle and rear sections;

[0032] The material transfer plate 4 is slidably connected to the inner wall on the other side of the feeding frame 1 and is located at the lower end of the material guide plate 3, and the front and rear ends of the material transfer plate 4 extend to the outside of the feeding frame 1 respectively. The top surface of the material transfer plate 4 and the corresponding position of the material guide plate 3 are arranged in a mesh shape, and a groove is opened at the front end inside the material transfer plate 4, and the inner wall of the bottom of the groove is arranged in an inclined surface. The rice husks are transmitted to the material transfer plate 4 through the progressive layers of the rice stalks and are located at the mesh surface, and the broken rice husks in the rice stalks are screened through the mesh so as to be collected separately.

[0033] The three groups of chutes 301 are provided with a material distribution mechanism 5, which includes a plurality of rotating rods 51, which are respectively equidistantly penetrated and rotatably connected to the three groups of chutes 301, and the middle section of each group of rotating rods 51 and located in the middle chutes 301 are fixedly installed with a limited gear 52, and the front and rear ends of the rotating rods 51 and located in the front and rear chutes 301 are fixedly sleeved with a cylinder 53, and the outer wall of the cylinder 53 is provided with a baffle 54, and the positions of the two adjacent groups of baffles 54 on the left and right are arranged in a vertical distribution;

[0034] A cylinder 55 is arranged on the inner wall of the higher side of the middle slide 301, and the output shaft of the cylinder 55 is fixedly connected to a slide frame 56 through a push rod. The slide frames 56 are sleeved together on the outside of a plurality of groups of limit gears 52, and the bottom of the slide frame 56 extends to the outside of the slide 301, and the tooth groups staggeredly arranged on the top inner wall and the bottom inner wall of the slide frame 56 are respectively meshed with the plurality of groups of limit gears 52;

[0035] In specific operation, firstly, the piles of straw are thrown through the long feeding frame 2, and part of the straw piles are discharged through the gap between the bottom of the long feeding frame 2 and the end of the guide plate 3, and are received by the front and rear two groups of baffles 54 at the top of the guide plate 5. The single receiving amount is the amount received at the angle between the baffle 54 and the guide plate 5, so as to carry out quantitative material distribution;

[0036] Then the cylinder 55 is started to push the slide frame 55 to reciprocate by using the push rod, and the slide frame 55 and the plurality of limit gears 52 move relative to each other, and the plurality of limit gears 52 are respectively meshed with the tooth groups at the top or bottom inner wall of the slide frame 55, thereby realizing the synchronous rotation of the limit gears 52, the rotating rod 51 and the cylinder 53;

[0037] Since the teeth on the inner wall of the sliding frame 55 are staggered, the two adjacent groups of rotating rods 51 are forced to rotate in opposite directions, so the two groups of baffles 54 receiving the straw bundles rotate clockwise until the two groups of baffles 54 are flush with the guide plate 3, and the straw bundles are slid down to the adjacent baffles 54 through the guide plate 4, while the adjacent rotating rods 51 and baffles 54 rotate counterclockwise, and the baffles 54 originally flush with the guide plate 3 are turned over to be perpendicular to the guide plate 3;

[0038] The straw bundle slides downward to complete the first step of material transfer, and then the slide frame 55 moves in the opposite direction to realize the reset rotation of two adjacent groups of rotating rods, and this reciprocating process is used to realize the orderly transfer of straw bundle weight, thereby reducing the influence of disordered transfer on subsequent crushing efficiency.

[0039] Example 2: Please refer to Figure 4 - Figure 5 As shown, the bottom surface of the guide plate 3 is provided with a straightening assembly 6 at both ends, and the straightening assembly 6 is movably connected to the material distribution mechanism 5. The straightening assembly 6 is divided into two groups, and each group of the straightening assembly 6 includes a slide plate 61. The two groups of slide plates 61 are respectively fixedly installed at the two end positions of the bottom surface of the slide frame 56, and the bottom surface of the slide plate 61 is fixedly installed with a circular shaft 62 at the front and rear ends. The front and rear ends of the bottom surface of the slide plate 61 are respectively movably provided with an L-shaped clamping plate 63. The two groups of L-shaped clamping plates 63 are respectively slidably connected to the bottom surface of the guide plate 3 through a rectangular frame. One end of the L-shaped clamping plate 63 away from the slide plate 61 extends to the top surface of the guide plate 3, and the end of the L-shaped clamping plate 63 overlapping with the slide plate 61 is provided with an inclined groove 64. The two groups of circular shafts 62 are respectively slidably connected to the opposite ends inside the two groups of inclined grooves 64.

[0040] During the movement of the slide frame 56, the two groups of slide plates 61 move synchronously with the slide frame 56, and each group of slide plates 61 moves relative to the two groups of L-shaped clamping plates 63 adjacent to each other, and the round shaft 62 presses against the inner wall of the inclined groove 64, thereby forcing the two groups of L-shaped clamping plates 6 to be pulled closer to each other, and the straw bales of the first and last transmissions are straightened and clamped to avoid uneven layers of straw bales and straw bales transferred to the surface of the transfer plate 4; this structure can keep the straw neat during the first transmission and keep the straw bales neat and orderly falling onto the surface of the transfer plate 4 during the final transmission, so as to avoid the situation where the straw bales are uneven and chaotic during the subsequent transmission, so as to further improve the straw feeding and transmission efficiency.

[0041] Example 3: Please refer to Figure 1 , Figure 6 - Figure 7 As shown, a transmission rack 401 is fixedly installed on one side of the material transfer plate 4 away from the inner wall and located at the upper end of the groove, the bottom of the material transfer plate 4 is supported by two groups of rollers fixedly installed on the inner wall of the feeding frame 1, and a motor 402 is arranged on the inner wall of the material transfer plate 4 and located between the two groups of rollers, and a transmission gear 1 403 is fixedly installed at the output end of the motor 402, and the transmission gear 1 403 is meshed with a tooth group arranged on the bottom surface of the material transfer plate 4;

[0042] A roller pressing mechanism 7 is provided at the material transfer plate 4, and an inclined concave abutment frame 8 is hingedly connected to the front end of the feeding frame 1 at one side of the top frame, and a push roller 9 is rotatably connected to the inner wall of the concave abutment frame 8 at one end, and the push roller 9 is close to the surface of the material transfer plate 4;

[0043] The rolling mechanism 7 includes a plate 71, the center of one side of the plate 71 is hinged to the inner wall of the feeding frame 1 through a hinge rod, the inner wall of the feeding frame 1 is connected to a cylinder 72 through a fixed sleeve at the rear end of the plate 71, the rod body fixedly installed at the rear end of the plate 71 is hinged in the inner groove opened inside the cylinder 72, the bottom end of the cylinder 72 is inserted into a slot 73 opened in the center of the surface of the transfer plate 4, and the inner wall of one side of the slot 73 is inclined;

[0044] A pressure roller 74 is arranged at the front end of the bottom of the abutment plate 71, and one end of the pressure roller 74 close to the inner wall of the feeding frame 1 is rotatably connected to a sliding shaft 75, and the sliding shaft 75 is slidably connected to the inside of a vertical groove 76 opened at the inner wall of the feeding frame 1, and a damping spring shock absorber 77 is arranged at the lower end of the sliding shaft 75 in the vertical groove 76, and the other end of the pressure roller 74 extends to the outside of the material transfer plate 4 and is fixedly installed with a transmission gear 2 78;

[0045] The straw bundles put in batches are progressively introduced to the surface of the material transfer plate 4. At this time, the motor 402 drives the transmission gear 1 403 to rotate clockwise, and it meshes with the teeth at the bottom of the transmission plate 4 to realize the transmission of the material transfer plate 4 and force the straw bundle to move toward the pressure roller 74. At the same time, the material transfer plate 4 and the resistance cylinder 72 move relative to each other, so that the resistance cylinder 72 moves along the inclined surface of the card slot 73 toward the surface of the material transfer plate 4.

[0046] As a result, one end of the push tube 72 and the push plate 71 is lifted, the push plate 71 is tilted, and the other end of the push plate 71 presses the pressure roller 74 downward, the sliding shaft 75 simultaneously sinks downward along the inside of the vertical groove 76 and causes the damping spring shock absorber 77 to be compressed, and the transmission gear 2 78 sinks downward to the upper end of the transmission rack 401 with the pressure roller 74, and the transmission rack 401 moves synchronously with the material transfer plate 4 and meshes with the transmission gear 2 78, thereby realizing the self-rotation of the transmission gear 78 and the pressure roller 74, and the pressure roller 74 fully rolls the straw bales passing through in sequence by self-rotation;

[0047] This structure not only realizes the transmission and feeding of the straw bale, but also crushes and impacts the straw bale, which not only helps to accelerate the separation of rice husks remaining on the surface, but also makes it easy to compress the expanded volume of the straw bale, thereby improving the subsequent crushing efficiency.

[0048] After being continuously crushed by the pressure roller 74, some straws continue to pass through the bottom of the push roller 9 for a second crushing, and the bottom of the push roller 9 is resisted, causing the bottom of the concave resistance frame 8 to rise, until the straw bundle passes over the bottom of the push roller 9, and the push roller 9 is reset under the hinged rebound force of the concave resistance frame 8, and the compressed straw bundle is located at one end of the push roller 9. At this time, the motor 402 is used to drive the transmission gear 403 to rotate counterclockwise, and it is engaged with the teeth at the bottom of the transmission plate 4 to realize the reverse transmission of the transfer plate 4, forcing the straw and the push roller 9 to move in the opposite direction, and causing the compressed straw pile to gradually separate from the surface of the transfer plate 4 and merge into the crusher, and finally realize automatic feeding.

[0049] When the present invention is in use, the piled straw is thrown through the long feeding frame 2, and part of the straw pile is discharged through the gap between the bottom of the long feeding frame 2 and the end of the guide plate 3, and is received by the front and rear two groups of baffles 54 at the top of the guide plate 5. The single receiving amount is the amount received at the angle between the baffle 54 and the guide plate 5, so as to perform quantitative material distribution;

[0050] Then the cylinder 55 is started, and the push rod is used to push the slide frame 55 to reciprocate, and the slide frame 55 and the plurality of limit gears 52 move relative to each other, and the plurality of limit gears 52 are respectively meshed with the tooth groups at the top or bottom inner wall of the slide frame 55, so as to realize the synchronous rotation of the limit gears 52, the rotating rod 51 and the cylinder 53;

[0051] Since the teeth on the inner wall of the sliding frame 55 are staggered, the two adjacent groups of rotating rods 51 are forced to rotate in opposite directions, so the two groups of baffles 54 receiving the straw bundles rotate clockwise until the two groups of baffles 54 are flush with the guide plate 3, and the straw bundles are slid down to the adjacent baffles 54 through the guide plate 4, while the adjacent rotating rods 51 and baffles 54 rotate counterclockwise, and the baffles 54 originally flush with the guide plate 3 are turned over to be perpendicular to the guide plate 3;

[0052] The straw bundle slides downward to complete the first step of material transfer, and then the sliding frame 55 moves in the opposite direction to realize the reset rotation of the two adjacent groups of rotating rods, and this reciprocating process is repeated to realize the orderly transfer of the straw bundle weight;

[0053] At the same time, the two groups of slide plates 61 move synchronously with the slide frame 56, and each group of slide plates 61 moves relative to the two groups of L-shaped clamping plates 63 adjacent to each other, and the round shaft 62 presses against the inner wall of the inclined groove 64, forcing the two groups of L-shaped clamping plates 6 to be pulled closer to each other, and the straw bundles that are transmitted for the first and last time are straightened and clamped, so as to avoid the situation that the straw bundles that are transmitted layer by layer and the straw bundles that are transmitted to the surface of the transfer plate 4 are uneven;

[0054] The straw bundles put in batches are progressively introduced to the surface of the material transfer plate 4, and the motor 402 drives the transmission gear 1 403 to rotate clockwise, and it meshes with the teeth at the bottom of the transmission plate 4 to realize the transmission of the material transfer plate 4 and force the straw bundle to move toward the pressure roller 74. At the same time, the material transfer plate 4 and the resistance cylinder 72 move relative to each other, so that the resistance cylinder 72 moves along the inclined surface of the card slot 73 toward the surface of the material transfer plate 4;

[0055] As a result, one end of the push tube 72 and the push plate 71 is lifted, the push plate 71 is tilted, and the other end of the push plate 71 presses the pressure roller 74 downward, the sliding shaft 75 simultaneously sinks downward along the inside of the vertical groove 76 and causes the damping spring shock absorber 77 to be compressed, and the transmission gear 2 78 sinks downward with the pressure roller 74 to the upper end of the transmission rack 401, and the transmission rack 401 moves synchronously with the material transfer plate 4 and meshes with the transmission gear 2 78, so as to realize the self-rotation of the transmission gear 78 and the pressure roller 74, and the pressure roller 74 fully rolls the straw bales passing through in sequence by self-rotation;

[0056] Finally, after continuous rolling by the pressure roller 74, some straws continue to pass through the bottom of the push roller 9 for secondary rolling. The bottom of the push roller 9 is resisted, causing the bottom of the concave resistance frame 8 to rise until the straw bundle passes over the bottom of the push roller 9, and the push roller 9 is reset under the hinged rebound force of the concave resistance frame 8, and the compressed straw bundle is located at one end of the push roller 9. At this time, the motor 402 is used to drive the transmission gear 403 to rotate counterclockwise, and it is engaged with the teeth at the bottom of the transmission plate 4 to realize the reverse transmission of the transfer plate 4, and the straw and the push roller 9 are forced to move in the opposite direction, so that the compressed straw pile gradually separates from the surface of the transfer plate 4 and merges into the crusher, and finally realizes automatic feeding.
