Description

Technical Field

[0001] The utility model belongs to the technical field of straw crushing, and particularly relates to a straw recycling and crushing device. Background Technique

[0002] After straw is crushed, it can be more easily mixed with the soil, accelerating decomposition and decay, providing nutrients for the soil, and improving the soil structure and fertility.

[0003] For example, a Chinese patent with the publication number CN219698501 U discloses a straw recycling and crushing device, including a main working box. A crushing and dust removal component is fixedly connected to the top of the main working box. The crushing and dust removal component includes a feeding hopper fixedly connected to the top of the main working box. Vertical baffles are fixedly connected to both sides of the top of the feeding hopper. An adjusting groove block is fixedly connected to one side of the vertical baffle. A central shaft is rotatably connected to the surface of the adjusting groove block. One end of the central shaft is fixedly connected to a flat plate, and a bolt penetrates through the surface of the flat plate. The utility model relates to the technical field of straw crushing. In this straw recycling and crushing device, through the setting of the crushing and dust removal component, the device can spray water on the straw being crushed through a nozzle. The water mist directly adheres to the dust and debris. The debris during the crushing process directly drops, and the adjustment of the nozzle is adjustable, facilitating the quick operation of the staff, enabling it to adapt to multiple angles, and having a relatively high operation accuracy.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when in use. For example, straw crushing and returning to the field can increase the organic matter content in the soil, improve the soil structure, and enhance the soil fertility and water retention capacity. When this device is in use, after the straw is crushed, it cannot be returned to the field, and it still requires personnel to spread the crushed straw on the ground later, which is rather inconvenient, time-consuming, and laborious. Moreover, personnel generally directly spread the crushed straw on the ground, which will cause the straw to corrode at a slower speed. In view of this, we propose a straw recycling and crushing device. Content of the Utility Model

[0006] The purpose of the utility model is to provide a straw recycling and crushing device to solve the problems raised in the above background technique.

[0007] In view of this, the utility model provides a straw recycling and crushing device, including:

[0008] A storage shell, a crushing shell is fixedly installed on the top of the storage shell. Liquid storage boxes are fixedly installed on both sides of the top of the storage shell and located on both sides of the crushing shell. Crushing rods are symmetrically and rotatably installed in the crushing shell. A return pipe is fixedly installed below the crushing rods in the crushing shell, and a plurality of nozzles are fixedly installed in the return pipe;

[0009] A liquid supply assembly, which is located on one side of the crushing shell and is used to transport the decomposed agent in the two liquid storage boxes into the return pipe;

[0010] A driving assembly, which is located on the other side of the crushing shell and is used to drive the two crushing rods to rotate;

[0011] A discharge port, which is opened at the bottom of the storage shell. A through groove is opened in the storage shell. An electric push rod is fixedly installed in the through groove, and the output end of the electric push rod is fixedly installed with a baffle. The side of the baffle away from the electric push rod contacts the inner wall of the discharge port. Rollers are symmetrically and rotatably installed on both sides of the storage shell. A cavity is opened in the storage shell, and a dual-axis motor is fixedly installed in the cavity. The two output shafts of the dual-axis motor respectively penetrate through both sides of the cavity and are coaxially connected to the corresponding rollers.

[0012] In this technical solution, during use, the operator first opens the sealing covers on the feeding pipes of the two liquid storage boxes. Subsequently, water and the decomposed agent are put into the liquid storage boxes according to the ratio. Then, the sealing covers on the feeding pipes of the liquid storage boxes are closed. Then, through the provided driving assembly, the driving assembly drives the two crushing rods to rotate towards each other. Then, the operator puts the straw into the inner cavity of the storage shell from the feeding port of the storage shell. The straw will fall into the position between the two crushing rods. The two crushing rods rotating towards each other will break up the straw. At this time, through the liquid supply assembly, the liquid supply assembly transports the mixed liquid in the two liquid storage boxes into the return pipe. Then, the mixed liquid in the return pipe will be sprayed out from several nozzles. The sprayed mixed liquid will just spray on the broken straw that is falling downward, so that the broken straw will be attached with the mixed liquid. Then, the straw will fall into the storage shell;

[0013] Subsequently, start the dual-axis motor to make the two output shafts of the dual-axis motor drive the corresponding rollers to rotate. Then, the whole device will move. At this time, the other two rollers will also rotate together. Then, start the electric push rod to make the output shaft of the electric push rod contract. The output shaft of the electric push rod will drive the baffle to move towards the through groove, so that the baffle is no longer in the discharge port and the baffle will completely enter the through groove. At this time, the discharge port will be opened, and the broken straw in the storage shell will be discharged from the discharge port under the action of gravity. The whole device spreads the broken straw on the field while moving. And under the action of the mixed liquid, it can accelerate the corrosion speed of the straw, so that the straw can be decomposed more quickly in the field, thereby increasing the organic matter content in the soil, improving the soil structure, and enhancing the soil fertility and water retention capacity.

[0014] In the above technical solution, further, the liquid supply assembly includes:

[0015] The pump body is fixedly installed on one side of the crushing shell. A second water pipe is fixedly installed at the liquid inlet end of the pump body.

A first water pipe is fixedly installed at the liquid outlet end of the pump body, and one end of the first water pipe penetrates through one side of the crushing shell and is fixed to one side of the return pipe. The first water pipe communicates with the return pipe;

[0016] The connecting pipe has both ends fixedly installed on the two liquid storage boxes respectively, and the connecting pipe communicates with the inner cavities of the two liquid storage boxes.

[0017] In this technical solution, when the pump body is started, the pump body draws the mixed liquid of the decomposing agent and water located in one of the liquid storage boxes through the second water pipe. Subsequently, the mixed liquid in the second water pipe will enter the first water pipe. Then, the mixed liquid in the first water pipe will enter the return pipe. At the same time, the mixed liquid in the other liquid storage box will enter one of the liquid storage boxes through the connecting pipe. Then, the mixed liquid in the return pipe will be sprayed out from several nozzles, and the sprayed mixed liquid will just be sprayed on the straw that is broken and falling downward, so that the broken straw will be attached with the mixed liquid.

[0018] In the above technical solution, further, one end of the first water pipe is closely welded to one side of the crushing shell and one side of the return pipe, and the connecting pipe is in a "U" - shaped structure.

[0019] In this technical solution, it ensures the structural stability of the first water pipe; and ensures that the connecting pipe can connect the two liquid storage boxes.

[0020] In the above technical solution, further, the drive assembly includes:

[0021] Two gears. Both of the two gears are rotatably installed on the other side of the crushing shell. One end of each of the two gears penetrates through the other side of the crushing shell and is coaxially connected to the corresponding crushing rod. An L - shaped plate is fixedly installed on the other side of the crushing shell and below one of the gears. A motor body is fixedly installed on one side of the L - shaped plate. The output shaft of the motor body penetrates through one side of the L - shaped plate and is coaxially connected to one of the gears.

[0022] In this technical solution, when the motor body is started, the output shaft of the motor body drives one of the gears to rotate. Under the action of meshing, one of the gears will drive the other gear to rotate. Then, the two gears will respectively drive the two crushing rods to rotate towards each other.

A return plate is fixedly installed at the top of the return pipe inside the crushing shell, and the return plate is located below the crushing rods.

[0026] In this technical solution, under the action of the two guide plates, the straw will fall into the position between the two crushing rods; under the action of the return plate, the crushed straw can be prevented from falling on the return pipe.

[0027] In the above technical solution, further, the nozzle is communicated with the inner cavity of the return pipe, and the output shaft of the double-shaft motor is rotationally connected to the cavity and the storage shell.

[0032] 1. When the straw recycling and crushing device is in use, through the arranged driving assembly, the driving assembly drives the two crushing rods to rotate towards each other. Then, the operator puts the straw into the inner cavity of the storage shell from the feeding port of the storage shell, and the straw will fall into the position between the two crushing rods. The two crushing rods rotating towards each other will crush the straw. At this time, through the liquid supply assembly, the liquid supply assembly transports the mixed liquid in the two liquid storage boxes to the return pipe. Then, the mixed liquid in the return pipe will be sprayed out from several nozzles, and the sprayed mixed liquid will just be sprayed on the crushed and falling straw, so that the crushed straw will be attached with the mixed liquid.

[0083] Working principle: When in use, the operator first opens the sealing covers on the feeding pipes of the two liquid storage boxes 3. Then, water and the composting agent are put into the liquid storage boxes 3 according to the ratio. Subsequently, the sealing covers on the feeding pipes of the liquid storage boxes 3 are closed. Then, the motor body 7 is started, and the output shaft of the motor body 7 drives one of the gears 8 to rotate. Under the meshing effect, one of the gears 8 will drive the other gear 8 to rotate. Subsequently, the two gears 8 will respectively drive the two crushing rods 13 to rotate towards each other. Then, the operator puts the straw into the inner cavity of the storage shell 1 from the feeding port of the storage shell 1. Under the action of the two guide plates 4, the straw will fall into the position between the two crushing rods 13. The two crushing rods 13 rotating towards each other will break up the straw. At this time, the pump body 11 is started, and the pump body 11 extracts the mixed liquid of the composting agent and water in one of the liquid storage boxes 3 through the water pipe two 12.

[0084] Subsequently, the double-shaft motor 19 is started, and the two output shafts of the double-shaft motor 19 drive the corresponding rollers 9 to rotate. Then, the whole device will move. At this time, the other two rollers 9 will also rotate together. Then, the electric push rod 18 is started, and the output shaft of the electric push rod 18 contracts. The output shaft of the electric push rod 18 will drive the baffle 17 to move towards the through groove 22, so that the baffle 17 is no longer located in the discharge port 16, and the baffle 17 will completely enter the through groove 22. At this time, the discharge port 16 will be opened, and the broken straw in the storage shell 1 will be discharged from the discharge port 16 under the action of gravity. The whole device spreads the broken straw on the field while moving. And under the action of the mixed liquid, it can accelerate the corrosion speed of the straw, so that the straw can be decomposed more quickly in the field, thereby increasing the organic matter content in the soil, improving the soil structure, and enhancing the soil fertility and water retention capacity.
