Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery and equipment, and more specifically, to agricultural straw crushing equipment. Background Art

[0002] Straw is a general term for the stems and leaves (ears) of mature crops, usually referring to the remaining parts of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops (usually coarse grains) after the seeds are harvested. Straw contains more than half of the products of crop photosynthesis and is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter. It is a multi-purpose renewable biological resource and also a roughage. Straw needs to be crushed for secondary use and then put into use after being crushed.

[0003] The existing straw crushing equipment is used in the following scenarios: the straw crushing equipment is fixed at a designated position, and the straw is packed together in bundles with a length of 1.5M-2M. Then the staff picks up the straw, lifts it to the height of the crushing port of the crushing equipment, and pushes it downward into the crushing port of the crushing equipment. The crushing ports of different crushing equipment have different heights, generally between 1.3M and 1.6M. It is very inconvenient to carry out manual loading at this height, especially for some shorter people. Another problem is that since the bundled straw is long, the staff needs to manually support it for a while after putting it into the crushing port until the longer straw is crushed by half. During this process, some dust and even debris of the crushed straw in the crushing port will be sprayed out, affecting the loading operation of the staff outside the crushing port.

[0023] See also Figure 1-3An agricultural straw crushing equipment comprises a crusher body 1 and a feeding frame 9. The crusher body 1 supports the ground by setting a base 2 at the bottom. A feeding port 3 is set on one side of the upper end of the crusher body 1, and a collecting box 4 docking with the feeding port 3 is installed on the outer side of the crushing frame body 1. A fixing plate 5 is fixedly connected to the outer side of the crusher body 1, and an electromagnetic rail 6 is longitudinally fixedly connected to the outer side of the fixing plate 5. A matching electromagnetic block 7 is set on the outer side of the electromagnetic rail 6 for limited sliding. Two groups of mounting plates 8 are fixedly connected to the outer side of the electromagnetic block 7, and the feeding frame 9 is movably set between the two groups of mounting plates 8. A cutting table 10 docking with the feeding frame 9 is also fixedly connected to the upper end of the base 2, and a switch panel 11 is set on the front of the crusher body 1.

[0024] Among them, an exhaust fan 401 connected to the inner cavity and a box door are arranged on the outside of the collecting box 4, and an exhaust pipe 402 is also connected to the outer wall of the collecting box 4, and the exhaust pipe 402 is connected to the upper end of the feed port 3. When the straw enters the feed port 3 and is crushed, the dust and some debris generated by the crushing will be sprayed out from the feed port 3, which will pollute the environment around the feed port and also have a certain impact on the feeding. At this time, the exhaust fan 401 extracts the dust and debris on the outside of the feed port 3 through the exhaust pipe 402 and collects and stores them in the collecting box 4, which can ensure a relatively clean environment at the feeding position of the feed port 3, which is convenient for straw crushing.

[0025] Among them, the switch panel 11 includes an electromagnetic controller and a switch, and the electromagnetic controller electrically drives the electromagnetic block 7 to drive the feeding frame 9 to slide longitudinally along the electromagnetic rail 6. A stopper 601 for limiting the electromagnetic block 7 is also provided at the upper end of the electromagnetic rail 6. A support plate 801 is fixedly connected to the outer side of the mounting plate 8, and when the feeding frame 9 is horizontal, the support plate 801 is supported on the bottom of the feeding frame 9, and the inner end of the feeding frame 9 is fixedly connected to a limit plate 802, and the limit plate 802 is movably contacted and matched with the bottom of the feed port 3. Connecting shafts 901 are fixedly connected on both sides of the feeding frame 9, and the connecting shaft 901 is rotatably connected to the mounting plate 8 and movably extends to the outside thereof. A connecting disk 902 is fixedly connected to the outer end of the connecting shaft 901, and the connecting disk 902 is connected to the outer wall of the mounting plate 8 by a coil spring 903. In the default state, refer to the attached manual. Figure 2 As shown, the elastic restoring force of the coil spring 903 itself drives the bottom of the feeding frame 9 to connect with the upper end of the support plate 801. After the straw at the upper end of the feeding frame 9 is placed, the electromagnetic block 7 drives the feeding frame 9 to move upward along the electromagnetic rail 6 until the electromagnetic block 7 reaches the top of the electromagnetic rail 6 and is limited by the stop block 601. In this process, the limit plate 802 at the bottom of the feeding frame 9 will abut against the bottom of the feed port 3, which will drive the feeding frame 9 to rotate through the connecting shaft 901. At this time, the feeding frame 9 tilts and slides the straw at the upper end into the feed port 3 to realize automatic loading. In the process of the feeding frame 9 descending, the elastic restoring force of the coil spring 903 makes the feeding frame 9 return to its initial state and remain horizontal.

[0026] Among them, the upper end of the cutting table 10 is fixedly connected to a fixed frame 1001, the upper end of the fixed frame 1001 is fixedly connected to an electric push rod 1002, and the power end of the electric push rod 1002 is movable through the fixed frame 1001 and fixedly connected to a blade 1003. When in use, bundles of straw are placed on the cutting table 10 and the upper end of the feeding frame 9, and then the electric push rod 1002 presses down the blade 1003 to cut the straw. The cut straw is manually piled up on the upper end of the feeding frame 9 for feeding together.

[0027] Based on the above structure, when the device is in use, the staff places bundled straw on the cutting table 10 and the upper end of the feeding frame 9, and then uses the blade 1003 inside the cutting table 10 to cut the straw, and after cutting, all the straw is piled up on the upper end of the feeding frame 9. Then, the electromagnetic rail 6 is activated by the switch in the external switch panel 11 to drive the electromagnetic block 7 and the feeding frame 9 to slide up, and the feeding frame 9 connects and transports the straw at the upper end to the feed port 3 to realize automatic feeding, and realizes the straw crushing operation with the cooperation of the existing crusher body 1. The whole process reduces the difficulty of manual feeding, improves the overall working efficiency, and the practical effect is relatively obvious.
