Technical Field

[0001] The invention belongs to the field of rice transplanter equipment, and in particular relates to a transverse delivery times conversion structure of a transverse delivery box 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] The structure of the horizontal transfer box of the existing small rice transplanter is relatively complex, generally using transmission structures such as gears and chains, with a high failure rate, and the horizontal transfer speed is generally not convenient to adjust, and the scope of application is relatively narrow.

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

[0006] A lateral delivery frequency conversion structure of a lateral delivery box of a riding rice transplanter comprises a bracket, a lateral delivery box shell fixed on the bracket, and a power input shaft, a power transmission shaft and a screw shaft which are all rotatably arranged in the lateral delivery box shell through bearings, the power input shaft and the power transmission shaft are transmitted by meshing of bevel gears, one end of the power transmission shaft passes through the lateral delivery box shell, one end of the power transmission shaft is provided with a second lateral delivery gear, and the second lateral delivery gear is located outside the lateral delivery box shell; one end of the screw shaft passes through the lateral delivery box shell, one end of the screw shaft is provided with a first lateral delivery gear, and the first lateral delivery gear is located outside the lateral delivery box shell, the power transmission shaft and the screw shaft are transmitted by meshing of the second lateral delivery gear and the first lateral delivery gear, and a protective cover is also provided outside the second lateral delivery gear and the first lateral delivery gear, the screw shaft is provided with a guide groove, the slider is arranged in the guide groove, the slider reciprocates with the rotation of the screw shaft, and the slider is also provided with a guide column.

[0007] As a preferred solution: protective sleeves are provided on both sides of the guide column on the spiral shaft.

[0008] As a preferred solution: the transverse transfer box shell includes a first shell and a second shell fixed by bolts.

[0009] The present invention realizes the rotation of the screw shaft through the meshing transmission of the second transverse feeding gear on the power transmission shaft and the first transverse feeding gear on the screw shaft, thereby causing the sliding block on the screw shaft to reciprocate, thereby driving the guide column to reciprocate, and the second transverse feeding gear and the first transverse feeding gear are arranged outside the transverse transfer box shell and are equipped with separate protective covers, so that the second transverse feeding gear and the first transverse feeding gear can be replaced by opening the protective cover, and the transverse feeding speed can be changed by changing the tooth ratio of the second transverse feeding gear and the first transverse feeding gear, and the operation is convenient.
