Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery accessories, and in particular relates to a novel shaftless soil pressing roller. Background Art

[0002] In the field of agricultural machinery technology, the existing equipment used for rotary tillage of farmland generally has a soil crushing device towed behind it, the purpose of which is to crush the soil clods in the soil and press the broken straw or weeds in the soil into the ground.

[0003] Therefore, this product has existed in the field of agricultural technology for many years. Its general structure is to set a fixed shaft, two end plates are set on the fixed shaft, and multiple roller rods are set between the end plates. When the soil roller rotates, the soil is crushed by the roller rods.

[0004] The emergence of the soil roller mentioned above has made the surface soil of farmland well trimmed, but in actual operation, the technicians in this field have encountered new technical problems, as follows:

[0005] 1. This type of soil compacting roller is provided with a drive shaft. When the soil compacting roller rotates at high speed, weeds or vine-like stems and leaves on the ground surface are easily entangled on the drive shaft. When the entanglement is too much, the roller body speed is directly reduced or even dragged on the ground surface, making it impossible to achieve soil compacting operation;

[0006] 2. The roller rod on the existing soil-pressing roller is directly welded to the end plate when it is fixed. When the polygonal roller rod is used, the installation angle of the roller rod affects the soil-breaking effect;

[0007] 3. When using a polygonal roller bar, the outer corner of the roller bar is prone to lift up weeds when rotating, and the lifted weeds are entangled in the roller bar, affecting the soil crushing effect.

[0008] In view of the above-mentioned drawbacks, as technicians in this industry, it is very necessary to improve the soil pressing roller in the prior art, and effectively eliminate the new and various structural drawbacks existing in the prior art through structural improvement. Summary of the invention

[0009] In order to overcome the deficiencies of the prior art, the utility model provides a novel shaftless soil pressing roller, which has a novel structural design and can effectively eliminate various disadvantages of the prior art by improving the overall structure of the soil pressing roller.

[0010] In order to achieve the above technical objectives, the utility model adopts the following scheme: a new type of shaftless soil pressing roller, which includes end plates on left and right sides and several middle support plates therebetween, and several polygonal roller rods are fixed together by the end plates and the several middle support plates; the sharp corners of the polygonal roller rods face outwards and the sharp corners facing outwards are arranged in an arc shape; a support shaft is fixed on the end plate, the outside of the support shaft passes through the shaft head, and the shaft head passes through the hinged plate; the interior of the shaft head is matched with the support shaft to provide a sealing chamber and a bearing chamber, and the outer side of the shaft head is locked to the hinged plate as a whole.

[0011] The plurality of polygonal roller rods are evenly distributed on the end plates and the middle support plate, and are radially eccentrically arranged on the end plates and the middle support plate, with an eccentric angle A of 20 to 30 degrees.

[0012] The outer diameters of the end plates and the middle support plate are greater than 300 mm. If the outer diameters of the end plates and the middle support plate are too small, the small outer diameter size cannot improve the soil crushing efficiency when rotating.

[0013] The hinge plate is provided with two supporting points, one of which is used for hinge connection with the rotary tillage device, and the other supporting point is used for hinge connection with the lifting rod.

[0014] The polygonal roller rod is arranged in a trapezoidal structure, and the cross-sectional area thereof fixed in the end plate and the middle support plate is larger than the outer cross-sectional area.

[0015] The beneficial effects of the utility model are as follows: the utility model, through the above arrangement, includes end plates on the left and right sides and several middle support plates therebetween, and several polygonal roller rods are fixed together by the end plates and the several middle support plates; the utility model has a drive shaft without a center, which can prevent weeds from entangled with the drive shaft during rolling, thereby preventing the rotation of the drive shaft from being affected; the sharp corners of the polygonal roller rod face outward and the sharp corners facing outward are arranged in an arc shape, so that when rotating at high speed, straw weeds will not hang on the polygonal roller rod; a support shaft is fixed on the end plate, and the outer part of the support shaft passes through the shaft head, and the shaft head passes through the hinge plate arrangement; the interior of the shaft head cooperates with the support shaft to provide a sealing chamber and a bearing chamber, and the outer side of the shaft head is locked to the hinge plate as a whole, and the shaft head is detachable, and the internal bearing group can be replaced, which is easier to maintain than existing products.

DETAILED DESCRIPTION

[0024] As shown in the attached drawings, the utility model discloses a novel shaftless soil pressing roller, the specific structure of which is as follows:

[0025] It includes left and right end plates 1 and a plurality of middle support plates 2 therebetween, and a plurality of polygonal roller rods 3 are fixed by the end plates 1 and the plurality of middle support plates 2; the polygonal roller rods 3 are arranged in a trapezoidal structure, and the cross-sectional area fixed in the end plates 1 and the middle support plates 2 is larger than the cross-sectional area outside, and this structure can effectively improve the fixing strength of the polygonal roller rods 3 and prevent the polygonal roller rods 3 from being separated from the end plates 1 and the middle support plates 2. The utility model adopts the polygonal roller rods 3 instead of the small rolling tube structure, which has higher strength and better grass burying effect.

[0026] The pointed corners of the polygonal roller rod 3 face outwards and are arranged in an arc shape. When the polygonal roller rod 3 rotates at a high speed, the arc 32 of the polygonal roller rod 3 is separated from the ground at the rear side, which can prevent straw and weeds from hanging on the polygonal roller rod 3; a support shaft 6 is fixed on the end plate 1, and the support shaft 6 is arranged in a stepped shaft, which includes an external stepped shaft 61, a fixed disk 62 and a plug-in end 63. When installing, the plug-in end 63 is inserted into the shaft hole 12 of the end plate 1, and is locked together with the threaded hole 11 through a number of fixing holes on the fixed disk 62. The external stepped shaft 61 passes through the shaft head 7, and the shaft head 7 passes through the hinged plate 5; the interior of the shaft head 7 cooperates with the support shaft 6 to provide a sealing chamber 71 and a bearing chamber 72, and a multi-stage sealing structure is provided in the sealing chamber 71, and two sets of bearing groups are provided in the bearing chamber 72; the outer side of the shaft head 7 is locked together with the hinged plate 5.

[0027] When fixing, after the hinge plate 5 is fixed to the shaft head 7, the rotary tillage support point 52 is used to be fixed to the rotary tillage plough 4, and the lifting rod support point 53 is fixed to the lifting rod 13. The lifting rod 13 is convenient to install by screw connection, and can be fixed without gas cutting and welding.

[0028] The plurality of polygonal roller rods 3 are evenly distributed on the end plate 1 and the middle support plate 2. They are radially eccentrically arranged on the end plate 1 and the middle support plate 2. The eccentric angle A is 20 to 30 degrees, preferably 23 degrees. This structure allows the polygonal roller rods 3 to be centrifugal and radial. This angle setting is beneficial for pressing the straw underground.

[0029] Furthermore, the utility model limits the outer diameter of the end plate 1 and the middle support plate 2 to be greater than 300 mm. If the outer diameter of the end plate and the middle support plate is too small, the small outer diameter size cannot improve the soil crushing efficiency when rotating. When the outer diameter is greater than 300 mm, the rotation efficiency is higher and the soil breaking effect is better.

[0030] In summary, after the above configuration, the utility model includes end plates 1 on the left and right sides and a plurality of middle support plates 2 therebetween, and the end plates 1 and the plurality of middle support plates 2 are used together to fix a plurality of polygonal roller rods.

[0031] The utility model has a drive shaft without a center, which can prevent weeds from entangled with the drive shaft during rolling and affect the rotation of the drive shaft. The sharp corners of the polygonal roller rod 3 face outwards and are arranged in an arc shape. When rotating at high speed, straw weeds will not hang on the polygonal roller rod. A support shaft 6 is fixed on the end plate 1, and the outside of the support shaft 6 passes through the shaft head 7, and the shaft head 7 passes through the hinge plate setting; the inside of the shaft head is matched with the support shaft to set a sealing chamber 71 and a bearing chamber 72, and the outer side of the shaft head 7 is locked to the hinge plate 5. The shaft head 7 is detachable, and the internal bearing group can be replaced, which is easier to maintain than the existing products.
