Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of tillage equipment, and in particular to a four-wheel riding type mini-tiller. BACKGROUND

[0002] Traditional mini-tillers are generally hand-held, including a frame, a handrail, a power part, a gearbox, etc. The power part transmits torque to the gearbox for speed change through a clutch or a belt. The gearbox transmits torque to the drive axle after speed change to drive tillage tools such as rotary tillage, weeding, and ditching. However, the hand-held mini-tiller requires the operator to hold the handrail steadily and apply force downward. During tillage, a large vibration is generated. When turning, the operator needs to operate the handrail. The tillage and turning processes require a high level of skill from the operator and have a very high labor intensity.

[0003] Therefore, the applicant proposes an invention patent entitled Four-wheel Mini Tillage Equipment (Application No. 202211542800.7). In the patent, the four-wheel riding type mini-tiller allows the driver to ride on the mini-tiller for operation. The power mechanism drives the front gearbox and the rear gearbox through the engine, and combines with the tillage mechanism to realize a multi-gear four-wheel drive walking mode, a variety of four-wheel tillage modes, or a multi-gear two-wheel drive walking mode, which meets the tillage and walking needs in various regions such as dry land and paddy fields.

[0004] However, during subsequent use, it is found that when working in a paddy field, the mud and water at the bottom will splash due to the rotation of the walking wheels. The mudguards above the walking wheels are generally close to the footrests. The purpose is to block the mud and water splashing to the middle of the mini-tiller to protect the driver. However, the engine of the four-wheel riding type mini-tiller is arranged at the front side of the mini-tiller. Therefore, the existing mudguards have poor mud blocking effect on the engine. The mud and water may splash from the side to the side wall of the engine cylinder body, adhere and accumulate for a long time, thereby affecting the heat dissipation of the engine. In addition, the side wall of the cylinder body has a plurality of reinforcing ribs forming an angle with the outer wall, so that the mud and water adhering to the angle position are not easy to clean.

[0013] Beneficial effect: the bending part is arranged to shield the air guide cover part, so that the mud and water are prevented from blocking the air guide cover and affecting the heat dissipation effect.

[0014] As the preferred embodiment of the utility model, the first mounting hole is arranged on the side of the front mudguard close to the front walking wheel mudguard, and the second mounting hole is arranged on the side of the front mudguard close to the tillage mechanism connecting frame.

[0015] Beneficial effect: the first mounting hole is coincided with the original through hole of the front walking wheel mudguard, the through hole corresponding to the second mounting hole is arranged on the tillage mechanism connecting frame, so that the front mudguard is installed and fixed through the bolt, and the bolts on both sides make the front mudguard more stable.

[0016] As the preferred embodiment of the utility model, the front walking wheel mudguard supports the front mudguard.

[0017] Beneficial effect: the front walking wheel mudguard supports the front mudguard, and the two bolt mounting points make the structure more stable.

[0018] As the preferred embodiment of the utility model, the side of the front mudguard close to the front walking wheel mudguard is provided with an extension part, the extension part extends to contact one side edge of the front walking wheel mudguard, the extension part is provided with a supporting lug, and the first mounting hole is arranged on the supporting lug.

[0019] Beneficial effect: the contact of the two side edges makes the front mudguard and the front walking wheel mudguard have no gap, so that the mud and water are prevented from splashing between the two, and the front mudguard is prevented from being difficult to clean, the supporting lug is arranged, the extension part is combined, and positioning is facilitated during installation.

[0020] As preferred embodiments of the utility model, a plurality of third mounting holes are arranged on each front mudguard, and the front mudguard is mounted below the engine bottom plate through bolts.

[0021] Beneficial effects: The front mudguard is mounted below the engine bottom plate, which is convenient for dismounting and cleaning.

[0022] As preferred embodiments of the utility model, a plurality of through holes for bolt insertion are arranged on the engine bottom plate, and each third mounting hole is in one-to-one correspondence with the through hole on the engine bottom plate.

[0023] Beneficial effects: Since the engine bottom plate needs to be mounted with the bottom of the engine cylinder, the current mounting mode is to arrange corresponding through holes on the bottom of the engine cylinder and the engine bottom plate, and then lock through the inserted bolt and nut, therefore, the third mounting hole with the same position as the through hole is arranged on the front mudguard, and the original bolt and nut can be used for mounting, so that the engine bottom plate does not need to be additionally drilled and new fasteners are not needed, and therefore, the modification cost of the original engine model is low.
