Description

Technical Field

[0001] The utility model relates to crop processing equipment, in particular to crop straw processing equipment, belonging to the technical field of crop processing. Background Art

[0002] Crop straw is a general term for the stem and leaf parts of mature crops, usually referring to the remaining parts of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops after the seeds are harvested. After the crops are harvested, the edible parts are removed and the remaining straw needs to be processed separately. Crop straw can be crushed into animal feed or fermented to prepare fertilizer. In order to facilitate the crushing or fermentation of crop straw, it is often necessary to perform preliminary processing of the straw first, that is, the straw needs to be cut into small segments and then further processed.

[0003] In the prior art, a crop straw cutting device disclosed in announcement number CN219500019U includes a device housing and a cutting assembly located inside the device housing, wherein the cutting assembly is used to cut crop straws, can cut and process crop straws, and can adjust the feed rate according to the type of crop straws to improve the cutting effect. The prior art is also aimed at cutting and processing crop straws, but it can only improve the cutting efficiency, and when cutting crop straws, it only cuts the straws into straw segments of a certain length, and then further processes the straw segments. However, since crop straws often have a relatively The hard shell will make the straw segments unfavorable for subsequent deep processing if the shell cannot be further processed during the cutting process. For example, if cotton straw or corn straw is simply cut into straw segments, then in the further crushing or fermentation process, the relatively hard shell of the straw segment will affect the smooth crushing, that is, it will take a long time to completely crush the shell, which seriously affects the crushing efficiency. In addition, the relatively hard shell of the straw segment is not conducive to the decay of the straw during the fermentation process, and thus will also cause the fermentation time to be longer.

[0034] A bottom bracket 33 is provided below the rolling roller 3, and elastic support components are provided on both sides of the rolling roller 3. The bottom bracket 33 is fixedly connected to the support frame, and the two ends of the rolling roller 3 are rotatably connected to the elastic support components, and the elastic support components are respectively installed at the two ends of the bottom bracket 33, so that the rolling roller 3 can have the function of elastic adjustment up and down, and thus the rolling roller 3 can be lifted up to different heights according to the amount of straw fed, and the elastic support component always has an elastic force to pull the rolling roller 3 downward, so that the rolling roller 3 can feed the straw in a way that combines its own gravity with the downward pulling force. The rolling is performed to ensure that a good rolling effect can be achieved for straws with different feed amounts; a plurality of transverse cutting blades 4 are provided, and two groups of transverse cutting blades 4 are distributed up and down, and the two groups of transverse cutting blades 4 are coaxially connected to the cutting rotating rod 43, and the connection positions of the upper and lower groups of transverse cutting blades 4 on the cutting rotating rod 43 are staggered and stacked, which can realize cutting the upper and lower sides of the outer shell of the rolled straw body, so as to cut the outer shell of the straw body into multiple long strips, and the two groups of transverse cutting blades 4 stacked in a staggered manner can ensure finer cutting.

[0035] Embodiment 2

[0036] Improvements based on Example 1:

[0037] like Figures 1 to 8 As shown, feed baffles 11 are connected to both sides of the feed base plate 1, and a roller-type feed conveyor belt 2 is embedded in the plate body of the feed base plate 1 located at the front end of the rolling roller 3. When the straw material is placed on the feed base plate 1, the feed baffles 11 on both sides can prevent the straw material from falling, and the roller-type feed conveyor belt 2 can drive the straw material to be transported forward by rotating, so that the feeding operation of the straw material can be performed more labor-savingly.

[0038] Furthermore, the horizontal body of the bottom bracket 33 is located directly below the rolling bottom end of the rolling roller 3, and the horizontal body of the bottom bracket 33 is tightly connected to the lower plate surface of the feed bottom plate 1, which can form a bottom support for the feed bottom plate 1. When the rolling roller 3 rolls the straw material, the feed bottom plate 1 directly below the rolling roller 3 can be subjected to greater pressure, thereby ensuring that the feed bottom plate 1 will not be deformed when the straw material is rolled.

[0039] Furthermore, the elastic support assembly includes a rolling movable strut 32, a limiting link 34 and a pressure spring 35. The two ends of the rolling roller 3 are respectively rotatably connected to the rolling movable strut 32. The limiting link 34 is connected to the bottom of the rolling movable strut 32. The frame bodies at both ends of the bottom bracket 33 are provided with movable through holes 36, and the rod body of the limiting link 34 is inserted into the movable through holes 36. The limiting link 34 is located at the lower end of the bottom bracket 33 and is sleeved with a pressure spring 35. The pressure spring 35 is always in a compressed state, that is, it can make the bottom end of the rolling movable strut 32 in the initial state with the bottom end of the bottom bracket 33. The upper surface of the bottom bracket 33 is tightly attached together so that the rolling roller 3 is located at the lowest point in the initial state. When straw materials are transported to the rolling roller 3, the rolling roller 3 can crush the straw materials by rolling, and when the amount of straw materials transported is large, the rolling roller 3 will drive the rolling movable strut 32 to lift upward, and when the rolling roller 3 is lifted upward, the pressure spring 35 will be further compressed, that is, it will have a greater downward elastic force on the rolling movable strut 32, so as to provide a greater crushing pressure on the straw materials, ensuring that the outer shell of the straw body of more straw materials can be flattened.

[0040] Furthermore, a rolling motor 31 is fixedly connected to the outer side of one of the rolling movable struts 32, and the rotating shaft of the rolling motor 31 is coaxially connected to one end of the rolling roller 3. The rolling motor 31 can provide driving force to drive the rolling roller 3 to rotate, thereby realizing the rolling operation of the straw material.

[0041] Furthermore, one end of the two cutting rods 43 used to connect the upper and lower groups of transverse cutting blades 4 is connected to a synchronous drive assembly, and one of the cutting rods 43 is coaxially connected to a cutting motor 42. The cutting motor 42 can be used to rotate the cutting rod 43 to which it is connected, and the other cutting rod 43 can be driven to rotate under the action of the synchronous drive assembly, so that the upper and lower groups of transverse cutting blades 4 can respectively perform transverse cutting on the upper and lower sides of the outer shell of the straw body.

[0042] It should be noted that the outer sides of the upper and lower sets of transverse cutting blades 4 can be covered with protective covers to ensure that during the actual transverse cutting process, on the one hand, the protective covers can prevent straw debris from splashing during the cutting process, and on the other hand, the sharp transverse cutting blades 4 can be prevented from causing safety hazards to the workers.

[0043] Furthermore, the synchronous drive assembly includes a drive housing 41 and two drive gears 44. The two drive gears 44 are both rotatably connected in the drive housing 41, and the two drive gears 44 are meshingly connected. The two drive gears 44 are respectively fixedly mounted on one end of the two cutting rotating rods 43 located in the drive housing 41. The two cutting rotating rods 43 can be rotated in opposite directions through the transmission of the two drive gears 44, so that when the straw material is conveyed forward, the upper and lower side transverse cutting blades 4 can be rotated clockwise or counterclockwise relative to the conveying direction of the straw material, so that cutting can be performed more smoothly.

[0044] like Figure 1 , Figure 2 , Fig. 9 and Fig.10 As shown, the support frame includes an equipment support frame 6, support legs 61 and support connecting plates 62. The support frame 6 is C-shaped. The support connecting plates 62 are respectively connected to the tail ends of the horizontal frame bodies on both sides of the equipment support frame 6. The disconnected parts of the horizontal frame bodies on both sides of the equipment support frame 6 are connected with bottom brackets 33. The support legs 61 are respectively connected to the bottom ends of the horizontal frame bodies on both sides of the equipment support frame 6. The equipment support frame 6 is fixedly connected to the lower plate surface of the feed bottom plate 1. The support connecting plate 62 is located above the equipment support frame 6 and is rotatably connected to the cutting rotating rod 43, so that a stable support for the equipment support frame 6 can be formed through the support legs 61 and the support connecting plates 62, thereby ensuring stable support for the feed bottom plate 1, and ensuring that the feed bottom plate 1 and the feed assembly are combined together to form a stable structure.

[0045] Furthermore, the segmentation assembly 7 also includes a segmentation baffle 71 and a roller-type segmentation conveyor belt 72. The segmentation baffle 71 is respectively connected to one side of the supporting connecting plate 62, and the roller-type segmentation conveyor belt 72 is connected between the two segmentation baffles 71, and the conveying end of the roller-type segmentation conveyor belt 72 is arranged in a downward inclined state. The segmentation baffle 71 is connected to a cutting frame 73 just above the conveying end of the roller-type segmentation conveyor belt 72, so that the straw after transverse cutting can continue to be conveyed through the roller-type segmentation conveyor belt 72, and then when passing through the cutting frame 73, the gate cutter 74 movably connected to the cutting frame 73 can gate-cut the straw material longitudinally, that is, it can realize the flattening, cutting and segmentation processing of the straw material.

[0046] Furthermore, cutter limit grooves 75 are provided on the inner walls of the frame body on both sides of the cutter frame 73, and the two ends of the gate cutter 74 are movably clamped in the cutter limit grooves 75. The middle part of the horizontal frame body of the cutter frame 73 is connected to a reciprocating cylinder 5, and the telescopic end of the reciprocating cylinder 5 is fixedly connected to the middle part of the upper end of the gate cutter 74. The gate cutter 74 can be driven by the reciprocating cylinder 5 to move back and forth regularly up and down, that is, the gate cutting action of the straw material can be repeatedly performed, thereby realizing the continuous processing of the straw material by the equipment.

[0047] Working principle: by placing the straw material on the feeding bottom plate 1 and pushing it forward, when the straw material is conveyed to the crushing roller 3, the crushing roller 3 can crush the straw material by rolling, and when the amount of straw material conveyed is large, the crushing roller 3 will drive the crushing movable strut 32 to lift upward, and when the crushing roller 3 is lifted upward, the pressure spring 35 will be further compressed, that is, it will have a greater downward elastic force on the crushing movable strut 32, so as to provide a greater crushing pressure on the straw material, ensuring that the outer shell of the straw body of more straw material can be flattened, that is, the outer shell of the straw body can be flattened, and then the rotation of the cutting motor 42 drives it to The connected cutting rod 43 rotates, and under the action of the synchronous drive component, drives another cutting rod 43 to rotate, so that the upper and lower groups of transverse cutting blades 4 can respectively perform transverse cutting on the upper and lower sides of the outer shell of the straw body. The transverse cutting blades 4 can be used to perform transverse cutting along the direction of the straw body to cut the outer shell of the straw body. Finally, the straw body is longitudinally cut by the gate cutter 74 to cut the straw into multiple straw segments, that is, the processed straw can be the straw segment after the outer shell is flattened and cut, thereby improving the efficiency of deep processing during further deep processing such as fermentation or crushing in the later stage.
