[0034] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figure 1-2 As shown, this utility model provides a spreading device for a straw crushing and returning machine, comprising:

[0036] The shell 1 is provided with a feeding end and a dispensing end;

[0037] Tail plate 2 is installed at the spraying end of the housing 1, with one end hinged to the housing 1 and the other end having a protruding edge. The tail plate 2 can be opened or closed relative to the housing 1.

[0038] Side plates 3 are installed at both ends of the tail plate 2 and are connected to the shell 1 through an adjusting component. The position of the side plates 3 can be adjusted, thereby changing the opening and closing angle between the tail plate 2 and the shell 1, thus changing the range of straw being thrown backward.

[0039] Several combing boards 4 are arranged and installed at equal intervals on the inner side of the tail plate 2. The angle of the combing boards 4 relative to the tail plate 2 can be adjusted. When the material passes through the tail plate 2, the combing boards 4 can comb the straw. By adjusting the angle of the combing boards 4, the range and uniformity of the straw being thrown to one side can be changed.

[0040] in,

[0041] A reinforcing plate 5 is installed on the tail plate 2. The reinforcing plate 5 is arranged close to the shell 1, and its cross-section is L-shaped and arranged along the length of the tail plate 2 to ensure the straightness of the tail plate 2.

[0042] The working principle and beneficial effects of the above embodiments are as follows:

[0043] The material after the straw is crushed enters from the feed end of the shell 1 and is guided to the output of the throwing end. When the tail plate 2 is in the open state, the straw is thrown into the farmland through the throwing end. By adjusting the opening and closing angle of the tail plate 2 and the angle of the combing plate 4, the throwing range and uniformity of the straw can be controlled, so as to achieve effective return of straw to the field.

[0044] One end of the tail plate 2 is connected to the shell 1 via a hinge, allowing the tail plate 2 to open or close relative to the shell 1, facilitating control of the straw spreading process. The reinforcing plate 5 is installed on the tail plate 2, close to the shell 1. The reinforcing plate 5 is a stainless steel bent piece with an L-shaped cross-section, arranged along the length of the tail plate 2. This serves two purposes: first, to increase the connection strength between the tail plate 2 and the shell 1; and second, to enhance the structural strength of the tail plate 2, which is prone to deformation during opening and closing and when subjected to the force generated by the spreading of materials. This effectively ensures the straightness of the tail plate 2, preventing deformation and tearing during long-term use and ensuring the normal operation of the spreading device.

[0045] The present invention relates to a straw crushing and returning machine with a spreading device. The opening and closing design of the tail plate 2 and the angle adjustment function of the comb plate 4 can adjust the spreading range of straw and improve the uniformity of straw spreading. At the same time, the structural design of the reinforcing plate 5 enhances the structural strength of the tail plate 2, preventing deformation and tearing during long-term use and ensuring the long-term normal operation of the spreading device.

[0046] In one embodiment,

[0047] For example Figure 1 As shown, the aforementioned reinforcing plate 5 is installed on the shell 1 at one end near the tail plate 2. It is arranged along the length of the shell 1 to further enhance the connection strength between the tail plate 2 and the shell 1.

[0048] In one embodiment,

[0049] like Figure 3 , 5 As shown, the tail plate 2 is provided with first arc-shaped grooves at equal intervals. The combing plate 4 is connected to the tail plate 2 by bolts passing through the first arc-shaped grooves. By moving the bolts in the arc-shaped grooves, the combing plate 4 can be adjusted within a certain angle range, thereby better controlling the direction and uniformity of straw spreading.

[0050] In one embodiment,

[0051] like Figure 4 As shown, a U-shaped plate 6 is installed on the tail plate 2, and a second arc-shaped groove matching the first arc-shaped groove is opened on the U-shaped plate 6. The combing plate 4 is connected to the tail plate 2 by bolts passing through the first arc-shaped groove and the second arc-shaped groove.

[0052] The U-shaped design of the board 6 allows it to better distribute and bear the force, enhancing the connection strength between the combing board 4 and the tail board 2. During the spreading process, the straw will exert a certain force on the combing board 4 when it passes through the tail board 2. The U-shaped board 6 can effectively distribute these forces and prevent the combing board 4 from loosening or being damaged due to uneven force.

[0053] In one embodiment,

[0054] For example Figure 4 As shown, an elastic element 7 is installed between the housing 1 and the tail plate 2. The elastic element 7 includes a first buckle 71 installed on the housing 1, a second buckle 72 installed on the tail plate 2, and a spring 73 fastened between the first buckle 71 and the second buckle 72.

[0055] Spring 73 is fastened between the first buckle 71 and the second buckle 72, providing elastic force. The design of spring 73 allows the tail plate 2 to have a certain elastic deformation when subjected to external force, thereby reducing the impact force on the housing 1 and the tail plate 2.

[0056] It should be noted that:

[0057] When the elastic element 7 is activated, the adjusting element between the side plate 3 and the housing 1 needs to be loosened so that the tail plate 2 maintains a certain angle self-adjustment range.

[0058] In one embodiment,

[0059] The aforementioned protruding edge has a V-shaped cross section and is arranged at an angle to the tail plate 2. The aforementioned protruding edge is integrally bent and formed with the tail plate 2. The V-shaped cross section design gives the protruding edge better compressive and bending resistance, and it can withstand greater forces without deformation.

[0060] When the tail plate 2 encounters an obstacle during the turning or operation of the reamer, the raised edge design guides the tail plate 2 to flip over when it touches the obstacle, preventing it from getting stuck in the obstacle. This effectively reduces the curling deformation at the end of the tail plate and reduces safety issues caused by obstacles.

[0061] In summary:

[0062] This utility model discloses a straw pulverizing and returning machine with a spreading device. The opening and closing design of the tail plate and the angle adjustment function of the combing plate can adjust the spreading range of straw and improve the uniformity of straw spreading. At the same time, the structural design of the reinforcing plate enhances the structural strength of the tail plate, preventing deformation and tearing during long-term use and ensuring the long-term normal operation of the spreading device.

[0063] The U-shaped design of this utility model allows it to better distribute and bear the force, and enhances the connection strength between the combing board and the tail board. During the spreading process, the straw will exert a certain force on the combing board when it passes through the tail board. The U-shaped board can effectively distribute these forces and prevent the combing board from loosening or being damaged due to uneven force.

[0064] The tail plate of this utility model is designed with a raised edge at one end, which can guide the tail plate to flip over when it touches an obstacle, so as to avoid it getting stuck in the obstacle and improve the safety of the equipment.
