Description

Technical Field

[0001] The invention belongs to the field of rice transplanter equipment, and in particular relates to a walking control structure of a riding rice transplanter. Background Art

[0002] Rice transplanters are planting machines that plant rice seedlings in paddy fields. There are different types of rice transplanters. According to the state of the seedlings, they are divided into the type of pulling and washing seedlings, the type of seedlings with soil, and the dual-purpose type; according to the power, they are divided into two types: manual transplanters and motorized transplanters; according to the movement characteristics of the seedling separation and transplanting mechanisms, they can be divided into longitudinal rolling direct transplanting, longitudinal swing direct transplanting, and transverse swing direct transplanting; rice transplanters can be divided into walking rice transplanters, motorized rice transplanters, and high-speed rice transplanters. The composition of the planting parts of various transplanters is basically the same. The manual transplanter is composed of a seedling box, a seedling separation and transplanting mechanism, a frame, and a float, etc. The self-propelled motorized transplanter is also equipped with power drive, walking device, and seedling delivery mechanism. The basic working principle of the rice transplanter: the seedlings are placed neatly in the seedling box in a group state, and move horizontally with the seedling box, so that the seedling taker can take a certain number of seedlings one by one. Under the action of the transplanting trajectory control mechanism, the seedlings are inserted into the soil according to agronomic requirements, and the seedling taker then returns to the seedling box along a certain trajectory to take the seedlings.

[0003] Existing small rice transplanters are generally small in size and light in weight. They are bumpy when traveling on uneven fields and are prone to tilting when crossing large ditches. For safety reasons, the operator is generally required to get off the vehicle and hold the transplanter forward. At this time, the steering wheel needs to be locked to avoid accidents. Current rice transplanters do not have this structure. Summary of the invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide a walking control structure of a riding rice transplanter, which can make the rice transplanter always keep moving straight.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A travel control structure of a riding rice transplanter comprises a front frame, an armrest frame, a second pull rod, a locking rod, a steering wheel and a steering gear turntable, wherein the steering wheel is connected to the steering gear fixed to the front frame through a steering wheel shaft, and drives the steering gear turntable to rotate, and a locking notch is also provided in the middle of the front end of the steering gear turntable, the locking rod is L-shaped, a longer section is rotatably arranged at the lower part of the front frame, and a shorter section is engaged with or disengaged from the locking notch as the longer section rotates, the armrest frame is hinged at the front end of the front frame, and one side of the armrest frame is hinged to one end of the second pull rod, and the other end of the second pull rod is fixedly connected to the longer section of the locking rod.

[0007] As a preferred solution: a return spring is also sleeved on the second pull rod, one end of the return spring abuts against the end of the locking rod, and the other end of the return spring abuts against a positioning piece extending from the front frame.

[0008] As a preferred solution: the handrail frame is U-shaped as a whole and is made of hollow circular tubes.

[0009] As a preferred solution: steering rods are respectively hinged on both sides of the steering wheel.

[0010] The present invention provides a locking notch on the steering wheel, and provides an armrest frame at the front end of the front frame, and the armrest frame is connected with a locking rod. When the user needs to get off the vehicle and pull the rice transplanter by hand, the armrest frame is convenient for grabbing, and pressing the armrest frame downward can drive the locking rod to be clamped into the locking notch provided on the steering wheel, so that the steering machine cannot be easily rotated, thereby ensuring that the rice transplanter always moves forward and avoiding accidents.
