Description

Technical Field

[0001] This utility model relates to the technical field of agricultural tillage machinery parts, specifically an anti-weed serrated tillage wheel. Background Technology

[0002] Small agricultural tillage machinery, powered by small diesel or gasoline engines, is characterized by its light weight, small size, and simple structure. It is widely applicable to dry land, paddy fields, and orchards in plains, mountains, and hills. Its lightweight design allows for easy movement in the fields, making it convenient for users to operate and store. It eliminates the problem of large agricultural machinery being unable to access mountainous fields, making it the best alternative to oxen for farmers.

[0003] Small agricultural tillage machinery needs to be equipped with paddy field wheels when tilling in paddy fields. These wheels are the wheels that move and till the soil in the paddy field. When there is a lot of straw / weed in the paddy field, the roots / straw can easily get tangled on the paddy field wheels during tillage, and the wheels may even become jammed. The transmission mechanism and the paddy field wheels can also become clogged with straw / weed, increasing resistance and damaging the oil seal at the rotary shaft of the transmission mechanism. This renders the paddy field wheels unusable, forcing operators to stop the machine to clear the straw / weed and replace the oil seal before restarting, affecting normal operation and tillage efficiency. Therefore, it is necessary to design a tillage wheel that prevents straw entanglement and avoids damage to the oil seal caused by straw entanglement. Summary of the Invention

[0004] The purpose of this utility model is to address the problems existing in the prior art by providing an anti-grass-tangling serrated tillage wheel. This anti-grass-tangling serrated tillage wheel has a cleverly designed structure that prevents grass from tangling while maintaining tillage efficiency and avoiding damage to the oil seal caused by friction from tangled grass.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A serrated tillage wheel with anti-tangle features a hexagonal bushing for attaching and fixing to a rotary tiller shaft. Two or more serrated discs are fixedly connected at intervals along the hexagonal bushing. The bushing passes through the center of each serrated disc and is fixedly connected to it. The outer circumference of each serrated disc has serrations. Multiple anti-sinking plates are fixedly arrayed and fixedly connected between two adjacent serrated discs, centered on the hexagonal bushing. The two ends of each anti-sinking plate are fixedly connected to two adjacent serrated discs. The anti-sinking plates are arranged at an angle to the horizontal plane, ideally 30-45 degrees, when in contact with the soil, thus better preventing weed entanglement during tillage. During tillage, the serrated discs cut weeds into segments, reducing the probability of weed entanglement.

[0007] A further preferred arrangement: When there are three or more saw blades, the three adjacent anti-sinking plates between three adjacent saw blades are arranged in a triangular pattern, that is, one anti-sinking plate between the middle saw blade and the left saw blade, and two anti-sinking plates between the middle saw blade and the right saw blade are arranged in a triangular pattern. This triangular arrangement of the three adjacent anti-sinking plates improves the anti-sinking capability.

[0008] A further preferred design involves alternating right-angled and left-angled cutting plates fixed to the soil contact surfaces of multiple anti-sinking plates between adjacent sawtooth discs. Specifically, when a right-angled cutting plate is fixed to the soil contact surface of one anti-sinking plate, a left-angled cutting plate is fixed to the soil contact surface of another anti-sinking plate. This alternating arrangement of right-angled and left-angled cutting plates on adjacent anti-sinking plates improves soil fragmentation and enhances the ability to prevent grass entanglement.

[0009] A further preferred embodiment features an anti-entanglement ring cover at the end of the hexagonal bushing sleeve that inserts into the rotary tiller shaft. The anti-entanglement ring cover is fixedly mounted on the end of the hexagonal bushing sleeve. During installation, they are installed in pairs, symmetrically on the rotary tiller shaft of the agricultural machinery. The anti-entanglement ring cover covers the outer periphery of the oil seal between the rotary tiller shaft and the transmission box, preventing weeds from entangled around the oil seal and causing friction damage. The hexagonal bushing sleeve is provided with a pin hole for locking and connecting the rotary tiller shaft with a pin. After the rotary tiller shaft is inserted into the hexagonal bushing sleeve, a pin is inserted into the pin hole to prevent the rotary tiller shaft from loosening from the hexagonal bushing sleeve.

[0010] This anti-weed serrated tillage wheel has the following advantages:

[0011] 1. This anti-tangle sawtooth tiller has a cleverly designed structure. Two or more sawtooth discs are fixedly connected at intervals on a hexagonal bushing. Multiple anti-sinking plates are fixedly connected in an array between two adjacent sawtooth discs with the hexagonal bushing as the center. Without affecting the tilling effect, the sawtooth discs can cut weeds into segments, reducing the probability of weed entanglement.

[0012] 2. The contact surfaces of multiple anti-sinking plates between two adjacent sawtooth discs are alternately fixed with right and left oblique cutting plates. The alternating placement of the right and left oblique cutting plates on adjacent anti-sinking plates can better cut the soil and improve the ability to prevent grass from getting tangled.

[0013] 3. Install an anti-tangling ring cover at the end of the hexagonal shaft sleeve that is inserted into the rotary tiller shaft. The anti-tangling ring cover is fixedly installed at the end of the hexagonal shaft sleeve. During installation, the anti-tangling ring cover can cover the outer circumference of the oil seal between the rotary tiller shaft and the transmission box, so as to prevent weeds from getting tangled around the outer circumference of the oil seal between the rotary tiller shaft and the transmission box, which would cause friction damage to the oil seal.

[0022] To provide a more detailed description of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings. Example

[0023] like Figures 1-5 As shown, an anti-weed serrated tillage wheel includes a hexagonal bushing 4 for fitting and fixing onto a rotary tiller shaft. Two or more serrated discs 1 are fixedly connected at intervals on the hexagonal bushing 4. The hexagonal bushing 4 passes through the center of the serrated discs 1 and is fixedly connected to them. The outer periphery of the serrated discs 1 is serrated. Multiple anti-sinking plates 3 are fixedly connected in an array between two adjacent serrated discs 1, centered on the hexagonal bushing 4. The two ends of each anti-sinking plate 3 are fixedly connected to two adjacent serrated discs 1. The anti-sinking plates 3 are arranged at an angle to the horizontal plane, preferably 30-45 degrees, which better prevents weed entanglement during tillage. During tillage, the serrated discs 1 cut weeds into segments, reducing the probability of weed entanglement.

[0024] like Figure 1 and Figure 2 As shown, when there are three or more sawtooth discs 1, the three adjacent anti-sinking plates 3 between three adjacent sawtooth discs 1 are arranged in a triangular pattern. That is, the anti-sinking plate 3 between the middle sawtooth disc 1 and the left sawtooth disc 1, and the two anti-sinking plates 3 between the middle sawtooth disc 1 and the right sawtooth disc 1 are arranged in a triangular pattern. The triangular arrangement of the three adjacent anti-sinking plates 3 can improve the anti-sinking capability.

[0025] like Figure 1 , Figure 2 and Figure 5 As shown, the contact surfaces of multiple anti-sinking plates 3 between two adjacent sawtooth discs 1 are alternately fixed with right-angled cutting plates 5 and left-angled cutting plates 6. That is, when a right-angled cutting plate 5 is fixed on the contact surface of one anti-sinking plate 3, a left-angled cutting plate 6 is fixed on the contact surface of another anti-sinking plate 3. The alternating placement of the right-angled cutting plates 5 and left-angled cutting plates 6 on adjacent anti-sinking plates 3 can better cut the soil and also improve the ability to prevent grass from getting tangled.

[0026] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the hexagonal bushing 4 has an anti-tangling ring cover 2 at the end that inserts into the rotary tiller shaft. The anti-tangling ring cover 2 is fixedly installed on the end of the hexagonal bushing 4. During installation, the anti-tangling ring cover 2 can cover the outer periphery of the oil seal between the rotary tiller shaft and the transmission box, preventing weeds from getting tangled around the outer periphery of the oil seal between the rotary tiller shaft and the transmission box, which would cause friction damage to the oil seal.
