Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of straw crushing devices, specifically a straw crushing device for returning straw to the field with coarse and fine separation function. Background Technology
[0002] Straw is the stalk remaining after threshing crops. It's a general term for the stems and leaves of mature crops, typically referring to the residue left after harvesting grains from crops such as wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane, tobacco, soybeans, hemp, melons, fruits, and vegetables. Depending on the crop, straw can be categorized as wheat straw, rice straw, corn straw, sorghum straw, soybean straw, peanut straw, potato straw, sweet potato straw, etc. The cross-sectional structure of straw varies depending on the crop, but generally includes the epidermal system, the basic system, and the vascular system. Wheat and rice straw are hollow with a relatively thin tissue thickness, while corn and sorghum straw are solid with large internodes.
[0003] Compared with existing technologies: existing straw pulverizing devices for returning straw to the field do not have a coarse-fine separation function, which may affect the decomposition rate of straw. Pulverizing devices without coarse-fine separation function will pulverize straw into particles of different sizes. These particles will decompose at different rates in the soil. Larger particles may be difficult to decompose quickly, while smaller particles may decompose too quickly, resulting in uneven distribution of organic matter in the soil.
[0004] Therefore, a straw crushing device with coarse and fine separation function for returning straw to the field is proposed. Utility Model Content

[0027] Example 1:
[0028] A preferred embodiment of the straw crushing device for returning straw to the field with coarse and fine separation function provided by this utility model is, for example... Figure 1-4 As shown: A straw crushing device for returning straw to the field with coarse and fine separation function includes an organic body 1. The front of the body 1 has a movable opening, and one side of the body 1 has a discharge port with a movable groove at the bottom of the inner wall of the discharge port. The other side of the body 1 has a fixed opening; a feed pipe 2 is set on the top of the body 1; a crushing roller 3 is set inside the body 1; a separation component 4 is set inside the body 1; and a dust suction component 5 is set on one side of the body 1. The separation component 4 includes: a separation part 41 set inside the body 1; and a drive part 42 set inside the body 1.
[0029] The top of the machine body 1 is connected to the bottom of the feed pipe 2, and the inner wall of the machine body 1 is rotatably connected to both ends of the crushing roller 3.
[0030] The separation part 41 includes: a fixing block 411, which is disposed inside the machine body 1; the outer wall of the fixing block 411 is fixedly connected to the inner wall of the machine body 1, a return spring 412 is fixedly connected to the top of the fixing block 411, a screening plate 413 is fixedly connected to one end of the return spring 412, a slide rail 414 is slidably connected to the outer wall of the screening plate 413, and one side of the slide rail 414 is fixedly connected to the inner wall of the machine body 1.
[0031] The separation part 41 includes: a collection box 415, which is disposed in the movable opening 1 of the body 1; the outer wall of the collection box 415 is adapted to the movable opening 1, and a handle 416 is fixedly connected to the front of the collection box 415.
[0032] The moving part 42 includes: a fixed platform 421, which is set on the back of the machine body 1; a motor 422 is fixedly connected to the top of the fixed platform 421, a rotating rod 423 is fixedly connected to the output end of the motor 422, a cam 424 is fixedly sleeved on the outer wall of the rotating rod 423, and one end of the rotating rod 423 passes through the back of the machine body 1 and extends into the interior to be rotatably connected to the inner wall of the machine body 1.
[0033] The drive unit 42 includes: a telescopic rod 425, which is set in the movable groove opened at the discharge port; the bottom of the telescopic rod 425 is fixedly connected to the bottom of the inner wall of the movable groove, and a baffle 426 is fixedly connected to the telescopic end of the telescopic rod 425, which is adapted to the movable groove.
[0034] Furthermore, in this embodiment, by starting the motor 422, the operation of the motor 422 drives the rotating rod 423 to rotate, and the rotation of the rotating rod 423 drives the cam 424 to rotate. When the cam 424 rotates to contact the bottom of the screening plate 413, it squeezes the screening plate 413 to make it rise. When the cam 424 rotates to no longer contact the screening plate 413, the return spring 412 drives the screening plate 413 to return to its original position. This process is repeated, causing the screening plate 413 to vibrate. Then, the telescopic rod 425 is activated, and the movement of the telescopic rod 425 drives the baffle 426 to retract, so that the straw that has passed through the screening plate 413 falls into the collection box 415, and the straw that has not passed through the screening plate 413 is discharged through the discharge port, thereby achieving the effect of separating coarse and fine straw after crushing.
[0035] Example 2:
[0036] Based on Embodiment 1, a preferred embodiment of the straw pulverizing device for returning straw to the field with coarse and fine separation function provided by this utility model is as follows: Figure 1-4 As shown: The vacuuming assembly 5 includes: a vacuum cleaner 511, which is located on the other side of the body 1; a vacuum cleaner pipe 512 is connected to the top of the vacuum cleaner 511, a flow divider 513 is connected to one end of the vacuum cleaner pipe 512, a vacuum head 514 is connected to one side of the flow divider 513, a delivery pipe 515 is connected to one side of the vacuum cleaner 511, and a collection box 516 is connected to one end of the delivery pipe 515.
[0037] The outer wall of the diversion plate 513 is fixedly connected to the inner wall of the fixed port. The front of the collection box 516 has a movable opening 2, and a collection box 2 517 is provided inside the movable opening 2. A handle 2 518 is fixedly connected to the front of the collection box 2 517.

[0039] In operation, the straw to be crushed is poured into the machine body 1 through the feed pipe 2, then the crushing roller 3 is activated to crush the straw. Next, the vacuum cleaner 511 is started. The operation of the vacuum cleaner 511, through the suction pipe 512, the diverter plate 513, and the suction head 514, sucks in the dust generated after crushing the straw inside the machine body 1. The sucked-in dust is then transported through the conveying pipe 515 to the collection box 517 in the collection box 516. Finally, the motor 422 is started. The operation of the motor 422 drives the rotating rod 423 to rotate, and the rotation of the rotating rod 423 drives the cam 424 to rotate. When the cam 424 rotates to contact the bottom of the screening plate 413, it squeezes the screening plate 413 and makes it rise. When the cam 424 rotates to no longer contact the screening plate 413, the return spring 412 drives the screening plate 413 to return to its original position. This process is repeated, causing the screening plate 413 to vibrate. Then the telescopic rod 425 is activated. The movement of the telescopic rod 425 causes the baffle 426 to retract, so that the straw that has passed through the screening plate 413 falls into the collection box 415. The straw that has not passed through the screening plate 413 is discharged through the discharge port, thereby achieving the separation of coarse and fine straw after crushing.
[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
