It can be understood that the specific embodiments described herein are only used to explain the related utility model, and not to limit the utility model. In addition, it should be noted that, for the convenience of description, only the parts related to the utility model are shown in the drawings.

[0024] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0025] Referring to Figures 1 to 4 The utility model provides a kind of straw smashing equipment for agricultural production, it include: workbench 1, smashing device 2, drying device 3.

[0026] In the embodiment, workbench 1 is cuboid. The table top of workbench has opposite sides in the width direction on the table top. The table top has opposite ends in the length direction on the table top.

[0027] As shown in Figure 3 And Figure 4 As shown in, the opposite sides of the table top of workbench 1 are rotatably installed with binding arc plate 11. Two binding arc plates 11 and table top form constraint channel b for accommodating straw.

[0028] Continue to refer to Figure 1The workbench 1 is provided with a portal frame 12 arranged at one end of the constraint channel b. The portal frame is arranged at one end of the workbench. A rough cutting blade 13 is arranged on the portal frame 12 in a lifting manner. In this embodiment, a lifting cylinder is arranged on the crossbeam of the portal frame. The fixed end of the lifting cylinder is arranged on the crossbeam of the portal frame. The lifting cylinder is arranged vertically. The rough cutting blade is arranged on the telescopic end of the lifting cylinder.

[0029] As shown in Figure 1 , Figure 2 , the workbench 1 is provided with an electric pushing assembly 14 arranged in a position-adjustable manner. The electric pushing assembly 14 is used to push the straw along the axial direction of the constraint channel so as to move the straw towards the rough cutting blade.

[0030] The electric pushing assembly 14 is aligned with the other end of the constraint channel b. The interior of the workbench 1 is formed with a receiving cavity c. The opposite ends of the workbench 1 are respectively provided with an inlet and an outlet a.

[0031] The crushing device 2 includes a support 21 arranged on the outer side of the rough cutting blade 13 away from the constraint channel b and a receiving tank 22 arranged on the support 21 in a tiltable manner. The crushing blade is rotatably arranged in the receiving tank 22.

[0032] The drying device 3 is arranged in the receiving cavity c. The drying device 3 includes two belt conveyors 31 and a hot air machine 32. The two belt conveyors 31 are arranged in a staggered manner. The input end of the high belt conveyor 31 is aligned with the inlet. The input end of the low belt conveyor 31 is arranged below the output end of the high belt conveyor 31. The output end of the low belt conveyor 31 is aligned with the outlet a.

[0033] In this embodiment, the straw is placed between the two binding arc plates on the tabletop. The two binding arc plates are closed (as shown in Figures 3 to 4 ) to bundle the straw in the constraint channel. After the straw is bundled in the constraint channel, the electric pushing assembly pushes the straw along the axial direction of the constraint channel so as to move the straw towards the rough cutting blade. After the straw moves below the rough cutting blade, the lifting cylinder is extended to cut the straw by the rough cutting blade, so that the straw forms a rough cutting straw. Under the continuous pushing of the electric pushing assembly, the tank opening of the receiving tank is opened to make the rough cutting straw fall into the receiving tank. After the tank opening of the receiving tank is closed, the crushing blade in the receiving tank further cuts the rough cutting straw to form straw pieces.

[0034] After the straw pieces are formed, the opening of the holding tank is opened and turned over, so that the straw pieces in the holding tank are input into the input end of the high belt conveyor through the lifting conveyor. At this time, the hot air machine in the holding cavity generates hot air to take away the moisture of the straw pieces on the high belt conveyor. Then, the straw pieces on the high belt conveyor are input onto the low belt conveyor, at which time the straw pieces are turned over again to further remove moisture on the low belt conveyor, so that the moisture content of the straw pieces reaches the expected moisture content. The straw pieces reaching the expected moisture content are output through the discharge port of the workbench.
