In this way, the fertilizers and straw composting agents can be automatically configured while the pulverizing knife rotary cuts and crushes the straw. Then, the power pump arranged inside the spray pipe sprays the fertilizers and straw composting agents configured inside the mixing barrel through the spray nozzle on the spray pipe.

[0017] 3. In the present invention, while the spray pipe sprays fertilizers to the fields through the spray nozzle, since the spray pipe is located above the crushing knife, the dust caused by the rotary cutting and crushing of the crushing knife can be reduced while the fertilizer is sprayed to fertilize the fields. Therefore, the dust reduction effect is further improved in combination with the dust-proof housing, and the field environment is further improved, reducing the impact of dust on people working in the fields. At the same time, the crushed straw can be fully mixed with the fertilizer and the straw composting agent while applying the fertilizer and the straw composting agent, thereby accelerating the composting of the straw.

[0029] See also Figures 1 to 4 As shown, the frame 1 is installed together with the tractor, and then when the straw is crushed in the field, the power device b21 is started, and the output end of the power device b21 drives the power shaft b27 to rotate. The power shaft a26 and the power shaft b27 are respectively provided with a gear a25 and a gear b28, and the gear a25 and the gear b28 are meshed with each other. Therefore, when the power shaft b27 rotates, the power shaft b27 is meshed with the gear a25 through the gear b28, and the power shaft b27 drives the power shaft a26 to rotate synchronously. Since the power shaft a26 and the power shaft b27 are respectively provided with a pulverizing knife 23 that rotates synchronously and in the opposite direction, The two groups of crushing knives 23 are arranged crosswise on the frame 1, so the power shaft a26 and the power shaft b27 will synchronously drive the crushing knives 23 to rotate, so that the crushing knives 23 work on the land to crush the straw. The two groups of crushing knives 23 rotate synchronously and in opposite directions, and the stabilizing effect of the limiting plate 24 can improve the straw crushing effect while preventing the straw from getting stuck in the crushing knives 23 and affecting the crushing effect of the crushing knives 23. At the same time, in the process of rotary cutting and crushing, the design of the dustproof shell 4 can effectively block the dust caused by the rotary cutting and crushing of the crushing knives 23, so as to prevent the dust from flying and affecting the environment, thereby affecting the people working in the fields.
[0030] The frame 1 is provided with a fertilizing mechanism 3 for cooperating with the crushing mechanism 2 to fertilize the land. The fertilizing mechanism 3 includes a storage bin 31 located on the frame 1. The storage bin 31 is provided with partitions a, b and c by partitions. The c partition on the storage bin 31 is penetrated by a power shaft c35. When the power shaft a26 rotates, the power shaft c35 is driven to rotate inside the c partition. The a partition and the b partition on the storage bin 31 are penetrated by a threaded shaft 37. The power shaft c35 rotates to drive the threaded shaft 37. The a partition 37 of the material storage bin 31 is provided with a mixing drum 36 located outside the power shaft c35, and one side of the mixing drum 36 is connected with a spraying pipe 32, which is located at the corner of the dustproof housing 4 and the spraying nozzle on the spraying pipe 32 is located above the crushing knife 23; two groups of closing plates 310 are arranged on the threaded shaft 37, and the two groups of closing plates 310 are respectively located in the a partition and the b partition of the material storage bin 31, and the a partition and the b partition of the material storage bin 31 are respectively A feed pipe 39 connected to the mixing barrel 36 is connected, and two closing plates 310 are movably connected to the two feed pipes 39 respectively; a feeding port is provided above the a partition and the b partition on the storage bin 31, and the threaded shaft 37 runs through the a partition and the b partition. A power ring b38 is fixed on the power shaft a26, and a power ring a33 is provided at one end of the power shaft c35. A synchronous belt a34 connected to the power ring b38 is provided on the power ring a33, and a synchronous belt b311 connected to the threaded shaft 37 is provided on the power shaft c35, and a stirring blade is provided on the surface of the power shaft c35. The outer sides of the two parts of the threaded shaft 37 located inside the a partition and the b partition are provided with threads, and bearing seats are installed on the two closing plates 310. The two bearing seats are respectively connected to the two parts of the threads on the threaded shaft 37 through a ball nut pair. When the threaded shaft 37 rotates, the two closing plates 310 move along the threaded shaft 37, and the two closing plates 310 cancel the closed connection with the two feed pipes 39 during the movement;
[0031] See also Figures 4 to 8As shown, during the rotation of the power shaft a26, the power shaft a26 drives the gear b28 to rotate, the power ring b38 drives the power ring a33 to rotate through the synchronous belt a34, the power ring a33 drives the power shaft c35 to rotate, and the power shaft c35 drives the threaded shaft 37 to rotate through the synchronous belt b311. Since the threaded shaft 37 runs through the a partition and the b partition, and since the outer sides of the two parts of the threaded shaft 37 located inside the a partition and the b partition are both provided with threads, and the two closing plates 310 are respectively connected to the two parts of the threads on the threaded shaft 37 through a ball nut pair, when the threaded shaft 37 rotates, the two closing plates 310 on the threaded shaft 37 move along the threaded shaft 37, and during the movement of the two closing plates 310, the two closing plates The gap between 310 and the two feed pipes 39 changes, so that the fertilizer and straw composting agent in the a and b partitions on the storage bin 31 enter the interior of the mixing barrel 36 through the feed pipes 39 respectively, and then are rotated and stirred by the power shaft c35, thereby automatically configuring the fertilizer and straw composting agent while the pulverizing knife 23 pulverizes the straw, and then the power pump provided inside the spray pipe 32 sprays the fertilizer and straw composting agent configured inside the mixing barrel 36 through the spray nozzle on the spray pipe 32 to fertilize the field, thereby automatically fertilizing the field during the pulverizing of the straw, saving manpower for fertilization, and avoiding the difficulty of walking in the field where the pulverizing of the straw is caused, which increases the difficulty of fertilization;
[0032] In addition, a feeding assembly can be arranged inside the a partition on the storage bin 31, and the feeding assembly includes a power device a and a feeding roller, and both are prior art, so that the fertilizer inside the a partition on the storage bin 31 automatically enters the interior of the mixing barrel 36 through the feeding pipe 39; in addition, the positions of the two closing plates 310 on the threaded shaft 37 or the sizes of the two closing plates 310 can be adjusted according to actual conditions, and then the size of the gap between the two closing plates 310 and the two feeding pipes 39 can be adjusted during the rotation of the threaded shaft 37, so that the ratio of the fertilizer and the straw composting agent entering the interior of the mixing barrel 36 can be adjusted, thereby automatically mixing according to a certain ratio and then mixing through the power shaft c35, which has high automation and saves a lot of manpower, and automatically mixes according to the ratio to avoid errors in manual mixing, which affects the nutritional effect of the fertilizer on the field;
[0033] In addition, while the spray pipe 32 is spraying fertilizer to the field through the spray nozzle, since the spray pipe 32 is located above the crushing knife 23, the fertilizer and straw composting agent can be fully mixed with the straw cut and crushed by the crushing knife 23 while being sprayed to fertilize the field. The dust-proof shell 4 further improves the dust reduction effect, further improves the field environment, and reduces the impact of dust on people working in the field.
[0034] Working principle: The frame 1 is installed together with the tractor, and then when the straw is crushed in the field, the power device b21 is started, and the output end of the power device b21 drives the power shaft b27 to rotate. The power shaft a26 and the power shaft b27 are respectively provided with gears a25 and gears b28, and the gears a25 and gears b28 are meshed with each other. Therefore, when the power shaft b27 rotates, the power shaft b27 is meshed with the gear a25 through the gear b28, and the power shaft b27 will drive the power shaft a26 to rotate synchronously. Since the power shaft a26 and the power shaft b27 are respectively provided with synchronous and reverse rotating crushing knives 23, the two groups of crushing knives 23 are arranged crosswise on the frame 1, so the power shaft a26 and the power shaft b27 will synchronously drive the crushing knives 23 to rotate, so that the crushing knives 23 work on the land to crush the straw. The design of the dustproof shell 4 can effectively block the dust caused by the rotary cutting and crushing of the crushing knife 23, and avoid the dust flying to affect the environment, thereby affecting the people working in the field.
[0035] During the rotation of the power shaft a26, the power shaft a26 drives the gear b28 to rotate, the power ring b38 drives the power ring a33 to rotate through the synchronous belt a34, the power ring a33 drives the power shaft c35 to rotate, and the power shaft c35 drives the threaded shaft 37 to rotate through the synchronous belt b311. Since the threaded shaft 37 runs through the a partition and the b partition, and since the outer sides of the two parts of the threaded shaft 37 located inside the a partition and the b partition are both provided with threads, and the two closing plates 310 are respectively connected to the two parts of the threads on the threaded shaft 37 through the ball nut pair, when the threaded shaft 37 rotates, the two threads on the threaded shaft 37 The closing plate 310 moves along the threaded shaft 37. During the movement of the two closing plates 310, the connecting gap between the two closing plates 310 and the two feeding pipes 39 changes, so that the fertilizer and water inside the a partition and the b partition on the storage bin 31 enter the interior of the mixing barrel 36 through the feeding pipe 39 respectively, and then are rotated and stirred by the power shaft c35. In this way, the fertilizer can be automatically configured while the crushing knife 23 is rotary cutting and crushing the straw. Then, the power pump arranged inside the spraying pipe 32 is used to spray the fertilizer configured inside the mixing barrel 36 through the spray nozzle on the spraying pipe 32 to fertilize the field.
[0036] In addition, while the spray pipe 32 is spraying fertilizer to the field through the spray nozzle, since the spray pipe 32 is located above the crushing knife 23, the dust caused by the rotary cutting and crushing of the crushing knife 23 can be reduced. Therefore, the dust reduction effect is further improved in combination with the dust-proof shell 4, further improving the field environment and reducing the impact of dust on people working in the field.
