Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery crop root treatment equipment, in particular to an embedded cutter head of a stubble cleaner. Background Technique

[0002] A stubble cleaner is an important mechanical equipment used for crushing crop residues and preparing the land in agricultural production. It is applicable to the root stubble treatment of various crops and crushes the root stubble and stalks by mechanical crushing.

[0003] In the past, the cutter heads of stubble cleaners or rotary tillers were all fixed with thin cutter heads on the driving roller, and then holes were drilled on the cutter head, and the thin stubble knives were fixed on its outer wall. The cutter head is easy to deform, the stubble knife is not firmly fixed, easy to lose the knife, and easy to break the knife. At least 12 screws are required to fix the stubble knife on one cutter head. When switching and installing the cutter head, the workload of the agricultural machinery operator is too large, the agricultural machinery operator is hard and tired, delaying the operation time and affecting the progress of land preparation. Content of the Utility Model

[0004] The purpose of the utility model is to provide one, so as to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An embedded cutter head of a stubble cleaner, including a cutter shaft support disk, wherein the outer wall of the periphery of the cutter shaft support disk is evenly provided with embedded limiting grooves, and the stubble knives are inserted inside the embedded limiting grooves;

[0007] The cutter shaft support disk includes a cutter shaft outer plate and a cutter shaft inner plate, and the two shaft outer plates are clamped on both sides of the cutter shaft inner plate;

[0008] The cutter shaft outer plate is provided with a fixing piece corresponding to the embedded limiting groove, which penetrates through the cutter shaft outer plate and the stubble knife.

[0009] Preferably, the cutter heads of every two adjacent stubble knives face in opposite directions and the cutting edges face in the same direction.

[0010] Preferably, fixing holes are arranged on the handle of the stubble knife.

[0011] Preferably, the two cutter shaft outer plates and the cutter shaft inner plate are welded and reinforced.

[0012] Preferably, a plurality of the embedded limiting grooves are inclined clockwise around a center.

[0013] Preferably, the width of the stubble knife and the embedded limiting groove is not more than 3 mm.

[0014] The design of the embedded cutter head of the stubble cleaner of the utility model has the following beneficial effects compared with the traditional cutter heads of stubble cleaners or rotary tillers:

[0015] Improved structural stability: By inlaying the stubble-breaking knives in the inlay limit grooves of the cutter shaft support disc instead of simply fixing them on the cutter disc, the structural stability of the cutter disc is enhanced, and deformation under high-load working conditions is reduced.

[0016] The blade is more firmly fixed: Through the combined use of the inlay limit groove and the fixing parts, the stubble-breaking knife is more firmly fixed, reducing the risk of blade loss or breakage during operation.

[0017] Easy installation and maintenance: Compared with the traditional cutter disc that requires multiple screws for fixation, this design reduces the workload of installation and maintenance. The agricultural machinery operator can replace and maintain the cutter disc more quickly, improving work efficiency.

[0018] Improved operation efficiency: Since the stubble-breaking knife fits closely against the inner wall of the inlay limit groove, the supporting force received by the stubble-breaking knife during work is more uniform, reducing additional wear and energy consumption caused by blade shaking and improving operation efficiency.

[0019] Design optimization: The design of the knife head orientation of the stubble-breaking knife is such that every two adjacent knife heads face in opposite directions and the cutting edges face in the same direction. This design helps to widen the stubble clearing area and improve the stubble-breaking effect.

[0020] Enhanced durability: The cutter shaft support disc is composed of an outer cutter shaft plate and an inner cutter shaft plate, and is reinforced by welding or bolts, enhancing the overall durability.

[0021] In summary, the embedded cutter disc design of the stubble-breaking machine of the present utility model improves the work efficiency, durability, and operation convenience of the stubble-breaking machine by optimizing the structure and installation method, and helps to improve the progress and quality of pre-tillage in agricultural production.

[0033] An embedded cutter head of a stubble-removing machine includes a tool shaft support disc 1. A sleeve shaft hole is provided at the center of the tool shaft support disc 1. The sleeve shaft hole is used for sleeving a driving roller shaft, and then the tool shaft support disc 1 is fixed on the roller shaft. The driving roller shaft rotates to drive the tool shaft support disc 1 to rotate.

[0034] Uniform inlaid limit grooves 2 are provided on the circumferential outer wall of the tool shaft support disc 1, and stubble-removing knives 3 are inserted inside the inlaid limit grooves 2; the stubble-removing knives 3 are sequentially inserted inside the inlaid limit grooves 2. Measure the length of the stubble-removing knives 3 on the outside and fix them uniformly.

[0035] It is preferably that the widths of the stubble-removing knives 3 and the inlaid limit grooves 2 are set to be similar, and the width difference is not more than 3 mm. When the stubble-removing knives 3 are working, the inner walls of the inlaid limit grooves 2 will give support forces to the stubble-removing knives 3. To avoid the fixing parts of the stubble-removing knives 3 from loosening due to long-term repeated stress, causing the stubble-removing knives 3 to shake in the inlaid limit grooves 2.

[0036] Among them, the tool shaft support disc 1 includes two outer plates 11 of the tool shaft and an inner plate 12 of the tool shaft. The two outer plates 11 of the shaft are clamped on both sides of the inner plate 12 of the tool shaft, thereby forming six slots, namely, inlaid limit grooves 2. The two outer plates 11 of the tool shaft and the inner plate 12 of the tool shaft can be fixed together by welding or by bolt reinforcement.

[0037] A fixing member penetrating through the outer plate 11 of the tool shaft and the stubble cutter 3 is provided corresponding to the embedded limiting groove 2 on the outer plate 11 of the tool shaft. Meanwhile, fixing holes are arranged on the handle of the stubble cutter 3. The fixing member uses the cooperation of a bolt rod and a nut. The bolt rod penetrates through the outer plate 11 of the tool shaft and the fixing holes to fix the stubble cutter 3. A plurality of fixing holes are provided to adjust the depth of insertion of the stubble cutter 3 into the inner side of the embedded limiting groove 2.

[0038] The cutting heads of every two adjacent stubble cutters 3 face in opposite directions and the cutting edges face in the same direction. According to the different directions of the cutting heads of the stubble cutter 3, the stubble cutter 3 is divided into a stubble cutter A 31 and a stubble cutter B 32. Among them, with reference to the rotation direction of the tool shaft support disc 1, the cutting edges of the stubble cutter A 31 and the stubble cutter B 32 face in the same direction, and the ends of the stubble cutter A 31 and the stubble cutter B 32 face the left and right sides of the rotation direction of the shaft support disc 1 respectively, so as to widen the stubble clearing area.

[0039] A plurality of the embedded limiting grooves 2 are inclined clockwise around a center.
