DETAILED DESCRIPTION

[0022] The utility model will make a detailed description below, obviously, the described example is only a part embodiment of the utility model, is not all embodiment. Based on the embodiment in the utility model, all other embodiments that the ordinary skilled in the art obtains under the premise of not making creative labor belong to the protection scope of the utility model.

[0023] As Figure 1 , 2 The utility model provides a mobile crop straw cutting machine, including: movable frame 1, install the feeding device 2 on frame 1, the feeding device 2 one side is provided with cutting device 3 and discharge device 4, cutting device 3 and discharge device 4 are connected with power mechanism, and the discharge end of discharge device 4 is provided with centrifugal discharge port 5.

[0024] Exemplarily, the feeding device 2 includes: liftable pressure mechanism 21, the feeding end of pressure mechanism 21 is provided with conveying mechanism 22:

[0025] As Figure 3 Exemplarily, the pressure mechanism 21 includes: pressure shell 211, the both sides of pressure shell 211 are provided with chute, the chute is provided with pressure roller 212, the upper surface of pressure roller 212 is provided with traction rod 213, traction rod 213 passes through shell 211 and is limited by pull ring 214, spring holder 215 is arranged on shell 211, spring 216 is installed in spring holder 215, and spring 216 is connected with pull ring 214. When the straw is less, pressure roller 212 can slide freely up and down, and the spring gives a certain pressure, when the straw is more, then it is very easy to open the wolf tooth roller, and the gap is adjusted. The feeding device speed can also be adjusted, and the cutter disc speed is constant, so that it is smoothly fed, cut by cutter disc system and sprayed out of the machine, and the cutting effect is completed.

[0026] Specifically, the conveying mechanism 22 includes: feeding roller 221, the distal end of feeding roller 221 is provided with feeding roller 222, a plurality of feeding knives are uniformly arranged on the circumferential direction of feeding roller 222, and the edge of feeding knife is wolf tooth structure.

[0027] Preferably, the frame 1 is provided with material collecting shell 7, the cutter disc 8 is arranged in material collecting shell 7, and the cutting device 3 and the discharge device 4 are arranged on the cutter disc 8.

[0028] Specifically, as Figure 4As shown, the cutting device 3 comprises: a moving knife 31 arranged on the cutter head 8, and the moving knife 31 is located at the side of the discharging device 4. The cutter head 31 is uniformly arranged with moving knives in the axial direction. For example, the cutter head 31 is uniformly arranged with three moving knives in the axial direction. After the straw is sent to the feeding device, the straw is conveyed through the feeding roller 222, clamped by the pressing mechanism 21, sent to the cutting edge, and then the blades on the cutter head 31 rotate to match and cut the straw. Through the pulse feeding, the cutting is repeated, and the uniform thin slices with a width less than 10mm are continuously cut.

[0029] As shown in the figure, Figure 4 As shown, the discharging device 4 comprises: a push plate 41 mounted on the outer ring of the cutter head 8, and the push plate 41 is matched with the material collecting shell 7. The device can rub, stir and push the cut material after centrifugation, and then the material is discharged from the discharge port, and the feeding purpose is achieved in rotation.

[0030] In order to facilitate the movement of the device, the bottom of the rack 1 is provided with a steering wheel, and the power mechanism is a diesel engine. In order to ensure safety, side guards are respectively arranged on both sides of the rack. In the utility model, the cutter head 8 is connected with the diesel engine, which can be set according to the actual production environment demand, and the application range is improved. The diesel engine is output to the main shaft, the main shaft rotates the cutter head 8 through the main belt pulley 10, and then synchronously drives the cutting device 3 and the discharging device 4 to rotate.

[0031] The working principle and process of the utility model are as follows:

[0032] The rack feeding device, cutting cutter head, cutter head or diesel engine, gearbox, cutting and battery of the straw cutting machine. The power is output to the main shaft, and then the main shaft rotates the cutter head 8, and then synchronously drives the cutting device 3 and the discharging device 4 to rotate. The cutter head 31 cuts the straw and other crops conveyed by the feeding device 2, and then rubs and rubs the debris through the push plate 41 and discharges.

[0033] In the working process of the utility model, the rotating speed of the feeding roller 222 in the pressing mechanism 21 is adjusted. When there are more straws, the rotating speed of the feeding roller 222 is reduced, and the rotating speed of the cutter head is unchanged. The pressing roller 212 is passively supported and has a certain pressure on the straw, and the feeding purpose is achieved in rotation; when there are less straws, the gap between the pressing roller 212 and the bottom plate is reduced under the action of gravity, so that the less straw is crushed and smoothly sent into the feeding port. The cutter head rotates to cut the straw, and the cutting effect is achieved. When the feeding is excessive and reaches the limit of the tension spring, the feeding can be automatically stopped, and the accumulated material can be automatically removed until the accumulated material is cut. At this time, the feeding roller 222 resumes feeding. In this way, the cutting is continuously repeated.

[0034] It is obvious for those skilled in the art that the above specific factual examples are only preferred schemes of the present application, therefore, the improvement and change of some parts of the present application made by those skilled in the art still embodies the principle of the present application, realizes the purpose of the present application, and belongs to the protection range of the present application.
