[0002] Crushed straw can be directly returned to the field to increase soil organic matter content, improve soil structure, and enhance soil fertility. It can also be used to make organic fertilizer to provide nutrients for crops. In addition, crushed straw can also be used to make silage or process straw pellet feed to improve the palatability and nutritional value of straw and provide high-quality feed for livestock.

[0003] Straw crushing requires the use of a straw crusher. However, current straw crushers are often large and inconvenient to carry. In addition, since straw is generally long and thin, operators often need to manually cut the straw into sections before putting it into the crusher, which is too labor-intensive and inefficient.

[0004] Therefore, a lightweight straw crusher was designed to solve the above problems. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a lightweight straw crusher that pre-cuts the straw before crushing, resulting in more thorough crushing and improved crushing efficiency.

[0026] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Embodiment 1

[0027] like Figure 1 As shown;

[0028] A portable straw crusher includes a main body 1, with four support legs 11 fixedly connected to the bottom surface of the main body 1, and handles 12 fixedly connected to both sides of the main body 1.

[0029] In this implementation plan: a straw crusher is required when crushing straw. However, current straw crushers are often large and inconvenient to carry. In addition, since straw is generally long and thin, operators often need to manually cut the straw into sections before putting it into the crusher, which is too labor-intensive and inefficient. To solve this technical problem, a crushing component 2 and a pretreatment component 3 are added.

[0030] Furthermore:

[0031] like Figures 1 to 5 As shown:

[0032] In combination with the above, it also includes:

[0033] The crushing assembly 2 includes two rotating rods 26 rotatably connected to the inner side of the main body 1 of the chassis. Crushing rollers 25 are fixedly connected to the surface of the rotating rods 26. The surfaces of the two rotating rods 26 are driven by the first synchronous belt pulley group 24. A servo motor 23 is installed on the outer surface of the main body 1 of the chassis. The output shaft of the servo motor 23 is fixedly connected to one of the rotating rods 26.

[0034] The pretreatment component 3 includes two mounting blocks 31 symmetrically fixedly connected to the inner surface of the main body 1. The two mounting blocks 31 are positioned above the crushing roller 25. The surface of the mounting blocks 31 is provided with a sliding groove 312. A slider 37 is slidably connected to the inner side of the sliding groove 312. A dividing blade 38 is fixedly connected between the two sliders 37. A baffle 39 is provided in front of the dividing blade 38 and is fixedly connected to the inner surface of the main body 1.

[0035] In this implementation scheme: the main body 1 of the chassis is the main frame structure of the entire straw crusher. The support legs 11 support the main body 1, ensuring its stability on the ground. The handle 12 facilitates the operator's movement of the straw crusher, making it more portable. The crushing assembly 2 is the key component for realizing the straw crushing function. Two rotating rods 26 are installed inside the main body 1 and can rotate. The crushing rollers 25 on the rotating rods 26 crush the straw when they rotate. The first synchronous pulley set 24 connects the two rotating rods 26, enabling them to rotate synchronously and ensuring uniform crushing effect. The servo motor 23, as the power source, is installed on the outer surface of the main body 1. Through its output shaft, it drives one of the rotating rods 26 to rotate, which in turn drives the other rotating rod 26 to rotate, realizing the crushing function of the crushing rollers 25.

[0036] The pretreatment component 3 performs preliminary treatment on the straw before it enters the crushing roller 25. The mounting block 31 is fixed inside the main body 1 and located above the crushing roller 25, providing a mounting position for subsequent components. A groove 312 is formed on the mounting block 31, allowing sliders 37 to slide within it. The dividing blades 38 connected between the sliders 37 can move as the sliders 37 slide. The dividing blades 38 are used to pre-divide the straw, cutting it into smaller segments before it enters the crushing roller 25 for easier subsequent crushing. A baffle 39 is installed inside the main body 1, in front of the dividing blades 38, to block the straw and ensure it is divided by the dividing blades 38 at the appropriate position.

[0037] Furthermore:

[0038] In an optional embodiment, a protective shell 21 is fixedly connected to the upper opening of the chassis body 1, and the protective shell 21 is trapezoidal.

[0039] In this embodiment, the protective shell 21 is fixed at the opening on the upper side of the main body 1. Its trapezoidal shape can prevent straw from splashing outward when it enters the main body 1, thus protecting the operator and the surrounding environment. It can also prevent debris from entering the main body 1 and affecting the normal operation of the machine. Furthermore, the trapezoidal appearance of the protective shell 21 provides space for subsequent structural operations.

[0040] Furthermore:

[0041] In an optional embodiment, two guide blocks 22 are fixedly connected to the inner side of the chassis body 1, and the two guide blocks 22 are respectively disposed below the two crushing rollers 25 on both sides.

[0042] In this embodiment, the guide ramp 22 is installed inside the main body 1 of the machine casing, located below the two crushing rollers 25 on both sides. Its function is to guide the straw after it has been crushed by the crushing rollers 25 to move smoothly downwards, preventing the straw from accumulating around the crushing rollers 25, so that the straw can be smoothly discharged from the main body 1 of the machine casing, ensuring the normal operation of the machine.

[0043] Furthermore:

[0044] In an optional embodiment, two rotating shafts 33 are symmetrically rotatably connected to the inner side of the chassis body 1, and the two rotating shafts 33 correspond to two mounting blocks 31 respectively. A rocker arm 34 is fixedly connected to the end of each rotating shaft 33. A push rod 35 is rotatably connected to the end of the rocker arm 34 away from the rotating shaft 33, and the end of the push rod 35 away from the rocker arm 34 is rotatably connected to the slider 37.

[0045] In this embodiment: Two rotating shafts 33 are symmetrically installed inside the main body 1 of the chassis, corresponding to two mounting blocks 31, providing rotational support points for the rocker arm 34. The rocker arm 34 is fixed to the end of the rotating shaft 33, and the operator can drive the push rod 35 to move by rotating the rocker arm 34. One end of the push rod 35 is rotatably connected to the rocker arm 34, and the other end is rotatably connected to the slider 37. Through this connection method, the rotation of the rocker arm 34 can be converted into the sliding of the slider 37 in the slide groove 312, thereby realizing the movement of the dividing blade 38, which makes it convenient for the operator to control the working state of the dividing blade 38.

[0046] Furthermore:

[0047] In an alternative embodiment, the shaft 33 is connected to one of the rotating rods 26 via a second synchronous pulley set 32.

[0048] In this implementation scheme: the rotating shaft 33 is connected to one of the rotating rods 26 via a second synchronous pulley set 32. When the rotating rod 26 rotates under the drive of the servo motor 23, the second synchronous pulley set 32 ​​drives the rotating shaft 33 to rotate. This allows the movement of the dividing blade 38 to be synchronized with the rotation of the crushing roller 25 during machine operation, improving the machine's automation level and work efficiency.

[0049] It should be noted that the first synchronous pulley group 24 and the second synchronous pulley group 32 have the same structure, both consisting of two synchronous pulleys and one synchronous belt.

[0050] Furthermore:

[0051] In an optional embodiment, a first connecting rod 36 and a second connecting rod 311 are fixedly connected between the two push rods 35, and the first connecting rod 36 is disposed between the two rocker arms 34, and the second connecting rod 311 is disposed between the two sliders 37.

[0052] In this embodiment: the first connecting rod 36 is connected between the two push rods 35 and located between the two rocker arms 34, and the second connecting rod 311 is connected between the two push rods 35 and located between the two sliders 37. The function of these two connecting rods is to make the movement of the two push rods 35 more coordinated and stable, ensure that the two sliders 37 can move synchronously, and thus enable the dividing blade 38 to perform the dividing work stably, improving the consistency of the dividing effect.

[0053] Furthermore:

[0054] In an optional embodiment, a guide slope 310 is provided below the baffle 39. The guide slope 310 is fixedly connected to the inner surface of the main body 1 of the chassis, and the end of the guide slope 310 corresponds to the contact point of the two crushing rollers 25.

[0055] In this embodiment, the guide slope 310 is installed on the inner surface of the main body 1 of the machine casing, located below the baffle 39, with its end corresponding to the contact point of the two crushing rollers 25. The function of the guide slope 310 is to guide the straw, after being divided by the dividing blade 38, smoothly into the space between the crushing rollers 25 for further crushing, ensuring that the straw can smoothly enter the crushing process and improving the working efficiency of the machine.

[0056] Working Principle: The main body 1 of the machine is the main frame structure of the entire straw crusher. The support legs 11 support the main body 1, ensuring its stability on the ground. The handle 12 facilitates the operator's movement of the straw crusher, making it more portable. The crushing assembly 2 is the key component for achieving the straw crushing function. Two rotating rods 26 are installed inside the main body 1 and can rotate. The crushing rollers 25 on the rotating rods 26 crush the straw during rotation. The first synchronous pulley set 24 connects the two rotating rods 26, enabling them to rotate synchronously and ensuring uniform crushing effect. The servo motor 23, as the power source, is installed on the outer surface of the main body 1. It drives one of the rotating rods 26 to rotate via its output shaft, which in turn drives the other rotating rod 26 to rotate, thus realizing the crushing function of the crushing rollers 25. The pretreatment assembly 3 performs preliminary treatment on the straw before it enters the crushing rollers 25. The mounting block 31 is fixed inside the main body 1 and located above the crushing rollers 25, providing a mounting position for subsequent components. A chute 312 is formed on the mounting block 31, and a slider 37 can slide within the chute 312. The dividing blades 38 connected between the sliders 37 can move as the sliders 37 slide. The dividing blades 38 are used for preliminary division of the straw, cutting it into smaller segments before it enters the crushing roller 25 for easier subsequent crushing. A baffle 39 is installed inside the main body 1, in front of the dividing blades 38, to block the straw and ensure it is divided by the dividing blades 38 at the appropriate position. A protective shell 21 is fixed to the opening on the upper side of the main body 1. Its trapezoidal shape prevents straw from splashing outwards when entering the main body 1, protecting the operator and the surrounding environment. It also prevents debris from entering the main body 1 and affecting the normal operation of the machine. Furthermore, the trapezoidal shape of the protective shell 21 provides space for subsequent structural operations. Guide blocks 22 are installed inside the main body 1, located below the two crushing rollers 25 on both sides. Its function is to guide the straw after it has been crushed by the crushing roller 25 to move smoothly downwards, preventing the straw from accumulating around the crushing roller 25 and allowing the straw to be smoothly discharged from the main body 1 of the machine, ensuring the normal operation of the machine. Two rotating shafts 33 are symmetrically installed inside the main body 1, corresponding to two mounting blocks 31, providing a support point for the rotation of the rocker arm 34. The rocker arm 34 is fixed to the end of the rotating shaft 33, and the operator can drive the push rod 35 to move by rotating the rocker arm 34. One end of the push rod 35 is rotatably connected to the rocker arm 34, and the other end is rotatably connected to the slider 37. Through this connection, the rotation of the rocker arm 34 can be converted into the sliding of the slider 37 in the slide groove 312, thereby realizing the movement of the dividing blade 38, which makes it convenient for the operator to control the working state of the dividing blade 38. The rotating shaft 33 is connected to one of the rotating rods 26 through the second synchronous pulley group 32. In this way, when the rotating rod 26 is driven by the servo motor 23, it can drive the rotating shaft 33 to rotate through the second synchronous pulley group 32.This allows the movement of the dividing blade 38 to be synchronized with the rotation of the crushing roller 25 during machine operation, improving the machine's automation and efficiency. The first connecting rod 36 connects between the two push rods 35 and is located between the two rocker arms 34, while the second connecting rod 311 connects between the two push rods 35 and is located between the two sliders 37. These two connecting rods ensure more coordinated and stable movement of the two push rods 35, guaranteeing synchronous movement of the two sliders 37, thus enabling the dividing blade 38 to perform stable dividing work and improving the consistency of the dividing effect. The guide slope 310 is installed on the inner surface of the main body 1, below the baffle 39, with its end corresponding to the contact point between the two crushing rollers 25. The guide slope 310 guides the straw, after being divided by the dividing blade 38, smoothly into the space between the crushing rollers 25 for further crushing, ensuring the straw smoothly enters the crushing process and improving the machine's efficiency.
