Description

Technical Field

[0001] The invention relates to the technical field of crop straw processing, and in particular to a mobile straw processing machine and a control method thereof. Background Art

[0002] Burning crop straw will cause the surface temperature to rise sharply, resulting in the burning of beneficial microorganisms in the soil, and the mineralization of humus and organic matter, thus destroying the ecological balance of the soil. Therefore, at this stage, crop straw should be recycled to achieve resource utilization, reduction and harmless treatment of straw.

[0003] Straw fertilizer making is an efficient and convenient way to process straw. It uses equipment such as straw biofertilizers to convert straw into organic fertilizer. The current processing machine is not mobile and can only pull crop straw from the fields to the processing workshop and put the crop straw into the auger box for processing. Although it can meet the production needs, it requires a transportation vehicle to transport crops, which is costly. In addition, the round-trip transportation of crop straw requires transportation time, resulting in low processing efficiency. In addition, the existing straw processing uses multiple augers to process crop straw, but the power sources of the multiple augers are derived from a single motor, so as many augers as there are, as many motors must be installed, which is costly, and if the entire equipment is moved outdoors for use, the power supply cannot be met.

[0020] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment, this embodiment provides a mobile straw processing machine, such as Figure 1 As shown, it includes an auger box 1, a hydraulic press, a travel component 3 and a diesel engine 2. A support frame 11 for supporting and installing the diesel engine 2 extends from the bottom of the auger box 1. The diesel engine 2 provides power for the hydraulic press and the travel component 3. The travel component 3 has a travel track. The diesel engine 2 and the travel component transmit power through a transmission belt. The travel track travels on gullies and potholes. It is mobile and can be moved to the fields to crush crop straw, which reduces costs and improves processing efficiency. It is suitable for agricultural production.

[0022] like Figure 1 As shown, it also includes an auger box 1, the upper part of which is opened for dropping crop straw.

[0023] It also includes multiple augers 415, which are rotatably arranged in the augers box 1, and the rotation directions of two adjacent augers 415 are opposite; specifically, two symmetrical backing plates 4 are fixed to the outer wall of one end of the augers box 1, a support plate 1 41 is fixed between the two backing plates 4, and two rotating connecting seats are fixed on the upper end surface of the support plate 1 41, and the ends of the two rotating connecting seats are respectively rotatably connected with a transmission disk 1 44 and a transmission disk 2 45, and the transmission disk 1 44 and the transmission disk 2 45 are respectively fixedly connected to one end of the two augers 415 that rotatably extend out of the augers box 1; a support plate 2 is fixed between the two backing plates 4, a hydraulic motor 42 is fixed on the upper end of the support plate 2, and an active roller 49 is fixedly connected to the output end of the hydraulic motor 42, and a belt 46 is wound around the outer wall of the active roller 49, and the belt 46 is wound around the bottom end of the outer wall of the transmission disk 1 44 and the upper end of the outer wall of the transmission disk 2 45.

[0024] In addition, a hydraulic valve 43 is fixed at the corner where the second support plate is connected to one of the support plates 4, and a hydraulic inlet pipe and a hydraulic outlet pipe are connected between the hydraulic machine and the hydraulic valve 43, and a hydraulic inlet pipe and a hydraulic outlet pipe are also connected between the hydraulic valve 43 and the hydraulic motor 42. The diesel engine 2 is connected to the hydraulic machine through a transmission belt to provide power for the hydraulic machine, so that the hydraulic machine can control the positive and negative directions of the power output of the hydraulic motor 42 through the hydraulic valve 43.

[0025] Also included is a tensioning member for tensioning the belt 46. Figure 4 As shown, specifically, the tensioning member includes a guide plate 47, which is fixed to one of the outer side walls of the support plate 4, a top plate 411 is horizontally fixed to the upper end of the side wall of the guide plate 47, a threaded rod 48 of an inverted T-shaped structure is threadedly inserted into the top plate 411, a threaded sleeve 412 of the threaded rod 48 is connected to the threaded sleeve 412, an I-shaped slider 413 is fixed to the radial side wall of the threaded sleeve 412, the guide plate 47 is provided with a guide hole for sliding engagement with the I-shaped slider 413, a gate frame 414 is fixed to the end of the I-shaped slider 413, a tensioning roller 410 is rotatably provided on the inner side wall of the gate frame 414, and the tensioning roller 410 is wound around the belt 46.

[0026] like Figure 1 , Figure 3 As shown, two screw auger 415 are provided here, and the winding method of belt 46 is: firstly bypassing the upper end of the outer wall of driving roller 49, then bypassing the bottom end of the outer wall of transmission plate 1 44 and the upper end of the outer wall of transmission plate 2 45 in sequence, and finally bypassing the tensioning roller 410. By rotating the threaded rod 48, the threaded rod 48 drives the threaded sleeve 412 and the I-shaped slider 413 to adjust the height along the axial direction of the threaded rod 48. When the I-shaped slider 413 slides along the wire hole, it will drive the tensioning roller 410 installed on the inner wall of the door frame 414 to rotate and adjust the height synchronously. This process can tension the belt 46, and the tension of the belt 46 can be adjusted as long as the driving roller 49 rotates without slipping. The above process is to adjust the tightness of the belt 46.

[0027] The next step is to provide rotational power for the auger 415. Specifically, the hydraulic press controls the positive and negative directions of the power output of the hydraulic motor 42 through the hydraulic valve 43. The hydraulic inlet and outlet hydraulic pipes of the hydraulic motor 42 serve as the inlet and outlet pipelines of the hydraulic oil, which can realize the control of the rotation direction of the active roller 49.

[0028] When the active roller 49 rotates forward, Figure 3 The belt 46 is driven accordingly, and the driving plate 44 and the driving roller 49 rotate in the same direction. Figure 3 In the q1 direction, the transmission plate 2 45 rotates in the opposite direction to the transmission plate 1 44, such as Figure 3 In the middle q2 direction, the corresponding tension roller 410 rotates in the same direction as the active roller 49. The two screw auger 415 rotate in opposite directions. On the contrary, when the active roller 49 reverses, that is, Figure 3 The belt 46 is driven in the opposite direction of the middle q, and the driving plate 44 and the driving roller 49 rotate in the same direction. Figure 3 In the opposite direction of q1, the transmission plate 2 45 rotates in the opposite direction to the transmission plate 1 44, such as Figure 3 In the opposite direction of q2, the corresponding tensioning roller 410 rotates in the same direction as the active roller 49.

[0029] The rotation direction adjustment process of the two augers 415 is as above. The next question is how to speed up the processing efficiency. Figure 5 As shown, a plurality of tamping rods 416 are provided on the outer wall of the auger 415. The auger 415 can drive the tamping rods 416 to rotate synchronously, and the rotating tamping rods 416 knock and break the crop straw.

[0030] A knife tooth 417 is provided at one side of the end of the ramming rod 416. The knife tooth 417 rotates synchronously with the rotating ramming rod 416 to cut the crop straw fibers.

[0031] Further, it also includes a loading plate 418, the two short side walls of the loading plate 418 are fixedly connected to the two opposite side walls in the auger box 1, and the two long side walls of the loading plate 418 are provided with a gap, and the side walls of the gap are used to support the crop straw, and the gap is used for the ramming rod 416 and the knife teeth 417 to rotate through, knock and break the straw rod body located directly above the gap, and cut the straw fiber located directly above. The gap is an L-shaped structure, one end of the gap is a longitudinal end 418A, and the other end is a transverse end 418B, the transverse end 418B is used for the ramming rod 416 to pass through, and the longitudinal end 418A is used for the knife teeth 417 to pass through, and the side walls of the gap opening can support the crop straw, so that when the crop straw contacts the ramming rod 416 and the knife teeth 417, it will not be pushed downward by the ramming rod 416 and the knife teeth 417, but will be directly broken and cut.

[0032] The two long side walls of the loading plate 418 extend obliquely downward on both sides of the auger box 1 to form an inverted V-shaped structure, which is used for crop straw to slide down the slope and prevent a large amount of crop straw from remaining on the upper end surface of the loading plate 418.

[0033] It should be noted that a spike portion 419 is fixed to the inner wall of the transverse end 418B. Figure 7 As shown, when the tamping rod 416 passes through the lateral end 418B, the crop straw can be pushed down into the lateral end 418B, contacted with the tip of the spike portion 419, and torn by the spike portion 419, which helps to speed up the breaking rate.

[0034] It should be noted that the width of the ramming rod 416 is smaller than the inner width of the transverse end 418B, and when the notched ramming rod 416 passes through the transverse end 418B, it does not contact the spike 419. The thickness of the blade teeth 417 is equal to the width of the inner wall of the longitudinal end 418A, and there is no gap between the blade teeth 417 and the inner wall of the longitudinal end 418A, so that when the notched blade teeth 417 pass through the longitudinal end 418A, it is clean and will not drive the straw into the longitudinal end 418A, causing the straw to be retained in the longitudinal end 418A.

[0035] Further, such as Figure 1 and Figure 2 As shown, the side walls of both sides of the auger box 1 are provided with discharge ports, the side walls of the discharge port opening are provided with a guide hopper 12, the inner wall of the guide hopper 12 is provided with an L-shaped baffle 15 near the discharge port, and a plug-in gap is formed between the L-shaped baffle 15 and the side walls of the discharge port opening, and a door panel 13 is slidably inserted in the plug-in gap. After the straw is crushed, the door panel 13 is slid upward along the plug-in gap, and the door panel 13 is pulled away from the discharge port, and the auger 415 rotates in the opposite direction to drive the crushed straw to the discharge port, and is discharged through the guide hopper 12 arranged tilted downward.

[0036] For greater convenience, a hinge seat is provided on the outer wall of the auger box 1 above the discharge port, and a hydraulic rod 14 is hinged at the bottom end of the hinge seat, and the telescopic end of the hydraulic rod 14 is fixedly connected to the side wall of the door panel 13. The hydraulic machine hydraulic rod 14 provides hydraulic pressure, and the extension and retraction of the hydraulic rod 14 is controlled by the inflow and outflow of hydraulic oil, thereby satisfying the automatic operation of pulling and drawing the door panel 13.

[0037] The present invention also discloses a control method for a mobile straw processor, comprising the following steps: A1. Crop straw is put into the upper opening of the auger box 1 and moved to the diesel engine 2. The diesel engine 2 provides power for the hydraulic press and the travel assembly 3. The machine is movable and moved to the field to perform straw crushing operation. A2. By regulating the forward and reverse rotation of the two augers 415, the augers 415 can drive the tamping rod 416 to rotate synchronously, and the rotating tamping rod 416 knocks and breaks the crop straw rod body. At the same time, the augers 415 are used to transfer the raw materials through the forward and reverse rotation, thereby accelerating the crushing rate of the crop straw; A3. After the straw is crushed, the door panel 13 is slid upward along the insertion gap, and the door panel 13 is pulled out from the discharge port. The auger 415 rotates in the opposite direction to drive the crushed straw to the discharge port, and is discharged through the guide hopper 12 arranged obliquely downward.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
