DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3, a straw crushing and returning agricultural machinery equipment, comprising an installation frame 1, a scattering mechanism, a crushing mechanism and a conveying mechanism, the scattering mechanism comprising an adjusting block 2, the adjusting block 2 is arranged inside the installation frame 1 and is rotatably connected to the installation frame 1, a dispersion roller 3 is fixedly connected to one side of the adjusting block 2, a mounting plate 4 is fixedly connected to both sides of the installation frame 1, a cylinder 5 is fixedly installed on one side of the installation plate 4, a guide block 6 is fixedly connected to the output end of the cylinder 5, a connecting rod 7 is rotatably connected to one side of the guide block 6, and the connecting rod 7 is rotatably connected to the dispersion roller 3. First, the uncrushed straw is put into the installation frame 1 from the entrance, and then the straw is crushed by the crushing mechanism, and the crushed straw is conveyed out by the conveying mechanism. When the straw is conveyed out, it will pass through the scattering mechanism, and the guide block 6 is driven to move by the cylinder 5. The guide block 6 will drive the dispersion roller 3 and the adjusting block 2 to rotate back and forth through the connecting rod 7 to scatter the crushed straw, which can prevent the straw from agglomerating and allow the straw to be evenly dispersed in the soil.

[0020] In one aspect of the present embodiment, after the straw enters the installation frame 1, the first motor 8 is started to drive the first roller 9 and the first transmission wheel 10 to rotate, and the first transmission wheel 10 drives the second transmission wheel 12 to rotate through the transmission belt 11, so that the second transmission wheel 12 drives the second roller 13 to rotate, and one end of the second roller 13 is rotatably connected to the installation frame 1. When the first roller 9 and the second roller 13 rotate, the crushing blade 14 is driven to rotate. The crushing blade 14 on the first roller 9 and the crushing blade 14 on the second roller 13 are staggered, so that the straw is crushed, and the crushed straw can fall onto the conveying mechanism for conveying.

[0021] In one aspect of this embodiment, when the crushed straw falls onto the transmission belt 17, the second motor 15 is started to drive the transmission roller 16 to rotate, and the transmission belt 17 is transmitted. At the same time, the transmission roller 16 will drive the stabilizing roller 18 to rotate through the transmission belt 17, and its limit plate 19 will also rotate, thereby transporting the crushed straw on the transmission belt 17 to the disintegration mechanism for disintegration, so that the crushed straw can be better dispersed into the soil.

[0022] In one aspect of the present embodiment, when in use, the armrest 22 facilitates the user to adjust the angle of the device, slide the bracket 28 into the slot 27, and then block the upper side of the entrance through the baffle 29, so that the straw can only enter the installation frame 1 from one side, which can prevent the operator from putting his hand deep into the installation frame 1, reducing the risk of misoperation. The placement plate 20 in the installation frame 1 is arranged obliquely, and the surface of the placement plate 20 is relatively smooth, so that the straw can slide to the entrance. The sliding ball 24 is slidably connected to the limit groove 23, so that the fixing rod 25 and the active connecting ring 26 can be adjusted at multiple angles, which is convenient for the agricultural vehicle to be connected to the device for use. After the agricultural vehicle is connected to the device, the universal wheel 21 is arranged so that the agricultural vehicle can pull the device to move together for processing, so that the device can crush and scatter the crushed straw into the soil.

[0023] The working principle of the utility model is as follows: when the straw crushing and returning agricultural machinery equipment is in use, the agricultural vehicle is connected to the equipment through a connecting ring 26, and then the device is driven by the agricultural vehicle to move slowly in the field. While moving, the operator can place the straw on the placing plate 20, and the straw will slide into the installation frame 1. After the straw enters the installation frame 1, the first motor 8 is started to drive the first roller 9 and the first transmission wheel 10 to rotate, and the first transmission wheel 10 drives the second transmission wheel 12 to rotate through the transmission belt 11, so that the second transmission wheel 12 drives the second roller 13 to rotate, and one end of the second roller 13 is rotatably connected to the installation frame 1, and when the first roller 9 and the second roller 13 rotate, the crushing blade 14 will be driven to rotate, and the crushing blade 14 on the first roller 9 and the second roller 13 will rotate. The crushing blades 14 on the two rotating rollers 13 are arranged in a staggered manner, so that the straw is crushed. When the crushed straw falls onto the transmission belt 17, the second motor 15 is started to drive the transmission roller 16 to rotate, and the transmission belt 17 is transmitted. At the same time, the transmission roller 16 will drive the stabilizing roller 18 to rotate through the transmission belt 17, and its limit plate 19 will also rotate, so as to transport the crushed straw on the transmission belt 17 to the scattering mechanism. Finally, the cylinder 5 is started to drive the guide block 6 to move. The guide block 6 will drive the dispersion roller 3 and the adjustment block 2 to rotate back and forth through the connecting rod 7 to scatter the crushed straw. The scattered straw is directly scattered into the soil, so that the straw can be evenly dispersed in the soil. All electrical equipment in this scheme is powered by an external power supply.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
