Description

Technical Field

[0001] This utility model relates to the field of hay-raking equipment technology, specifically an agricultural operation device with an anti-clogging hay-raking component. Background Technology

[0002] In agricultural production, hay raking is a crucial step in forage harvesting and straw processing. Traditional hay rakes use rotating raking teeth to gather loose hay or straw into strips for subsequent baling or transportation. However, the bearings and connecting structures of some components in existing hay rakes are exposed to the hay environment and lack self-cleaning design. Fine hay and dirt easily stick to the roots of the raking teeth or the rotating parts of the wheel. Long-term accumulation can increase rotational resistance and even cause jamming, requiring frequent shutdowns for cleaning and affecting operational efficiency.

[0003] While existing technologies may already offer solutions to the aforementioned problems, this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0005] Each of the aforementioned anti-clogging hay-raking components includes a mounting shaft, on which a first bearing is fixedly mounted. A flange is fixedly mounted on the outer ring of the first bearing, and a wheel is mounted on the flange. A through hole is formed in the center of the wheel, through which the mounting shaft passes. Hay-raking teeth are arranged in an array around the mounting shaft on the outer wall of the wheel. Each hay-raking tooth consists of a straight section and an outwardly flared section. A frame plate is mounted on one end of the mounting shaft, and a support rod is provided on the side wall of the frame plate corresponding to the hay-raking teeth. A brush strip is mounted on one end of the support rod.

[0017] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example: Please refer to Figure 1-3 An agricultural operation device with anti-clogging hay-raking components 2 includes a traction frame 1, and multiple anti-clogging hay-raking components 2 are arranged at equal intervals on both sides of the traction frame 1.

[0019] It should be noted that the traction frame 1 can adopt the frame used in existing hay rakes. Its specific structure and working principle are existing technologies and will not be described in detail here.

[0020] Specifically, each anti-clogging hay-raking assembly 2 includes a mounting shaft 201, on which a first bearing 202 is fixedly mounted. A flange sleeve 203 is fixedly mounted on the outer ring of the first bearing 202. A wheel 204 is mounted on the flange sleeve 203. A through hole is formed in the center of the wheel 204, through which the mounting shaft 201 passes. Hay-raking teeth 205 are arranged in an array around the mounting shaft 201 on the outer wall of the wheel 204. The hay-raking teeth 205 are composed of straight sections and outwardly flared sections. A frame plate 206 is mounted on one end of the mounting shaft 201. A support rod 207 is provided on the side wall of the frame plate corresponding to the hay-raking teeth 205. A brush strip 208 is mounted on one end of the support rod 207. Preferably, the brush strip 208 is movably fitted to the straight section of the hay-raking teeth 205.

[0021] It should be noted that the mounting shaft 201 can be connected to the frame by bolts or welding. The rake teeth 205, under the resistance of weeds or straw in the field, drive the wheel 204 to rotate. Through the connection between the wheel 204 and the flange sleeve 203, the wheel 204 drives the flange sleeve 203 to rotate on the mounting shaft 201 via the first bearing 202. The rake teeth 205 perform rake work. The outward-turned sections of the rake teeth 205 insert into the straw layer. Through the rotation of the wheel 204 and the outward-turned sections of the rake teeth 205, the straw is concentrated towards the center of the device. The arrayed rake teeth 205 form a continuous prying motion during rotation, achieving continuous grabbing and conveying of straw. Because fine fragments are generated during the straw prying process... When hay is blown up, it tends to accumulate near the rotating part of the wheel 204. Therefore, a frame plate 206, a support rod 207, and a brush strip 208 are designed. The frame plate 206 shields the outer end of the wheel 204, reducing the distance of hay from the rotating part of the wheel 204. The brush strip 208, fixed at one end of the support rod 207, fits against the straight section of the hay-raking teeth 205. When the wheel 204 rotates, the brush strip 208 continuously scrapes away the hay, soil, and residue stuck to the hay-raking teeth 205, preventing accumulation and clogging, ensuring the continuity of agricultural hay-raking operations, reducing the frequency of stopping to clean the hay-raking teeth 205, and improving work efficiency. The brush strip 208 can be made of elastic materials, such as nylon or rubber.

[0022] Specifically, multiple first bolts 209 are movably inserted through the flange sleeve 203 and the wheel 204, and each first bolt 209 is threaded with a nut 210 for detachable connection between the flange sleeve 203 and the wheel 204.

[0023] As a preferred and further option, a second bearing 211 is movably mounted on the mounting shaft 201, and a cover is fixedly mounted on the outer ring of the second bearing 211. Multiple second bolts 212 are movably passed through the cover, and one end of each second bolt 212 is threaded into the wheel 204. The multiple second bolts 212 are used to connect the cover and the wheel 204. During the rotation of the wheel 204, the cover is driven to rotate through the second bearing 211, which plays a role in balancing the rotation of the wheel 204.

[0024] As a preferred option, the cover is provided with multiple clearance notches 213, and the multiple clearance notches 213 are provided one-to-one with multiple first bolts 209. The clearance notches 213 are used to avoid the first bolts 209.

[0025] As a preferred and further option, the frame plate 206 is provided with a plurality of third bolts 214, one end of each third bolt 214 being threaded into one end of the mounting shaft 201. The third bolts 214 are used for the detachable connection between the frame plate 206 and the mounting shaft 201.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
