[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] The present invention provides a machine integrating trenching, seedling transplanting and fertilizing. A fertilizing mechanism is arranged on a frame to reduce the burden on a fertilizer. Fertilizing is completed by pushing the frame to move, and the required manpower is reduced. The fertilizer is contained in a fertilizer box, so that the amount of fertilizer applied is greatly increased, and labor is saved while the fertilization efficiency is higher. Moreover, the trench opener on the frame can allow the frame to expand the land to form a fertilizer trench for fertilization when it is pushed forward. The fertilizer will not be directly sprinkled on the soil surface, and nitrogen fertilizer will easily volatilize ammonia to affect the environment, and phosphorus and potassium fertilizers will not be easily absorbed on the soil surface. The present invention directly buries the fertilizer in the fertilizer trench opened by the trench opener, and ensures that the nutrients of the fertilizer are fully absorbed by the soil. The present invention has a simple structure, is easy to operate, and has high working efficiency. It has low requirements on the use environment and a wider range of applications.

[0017] Furthermore, the frame of the present invention is also provided with a seedling entry tube and a seedling planting tube, and the furrow opener opens a trench in the propulsion direction of the frame. The seedling body is placed in the seedling entry tube, and then the transmission mechanism drives the seedling planting tube to be inserted into the soil, thus completing the seedling planting operation. The present invention integrates the functions of furrowing, fertilizing and seedling planting, and can flexibly select various functions and various functional combinations for use, and has a wider range of applications.

[0018] Furthermore, the present invention drives the driven gear to rotate through the active gear, and the driven gear drives the cam to rotate. When the cam drives the roller to move, the roller has a tendency to move up and down, so that the seedling planting tube can perform the seedling planting operation. The present invention completes the seedling planting operation of the seedling planting tube through a set of transmission mechanism, which saves time and labor, and does not need to rely on too much manpower to work, thereby improving work efficiency and simultaneously improving production. Moreover, the cooperation of the active gear, the driven gear and the cam enables the seedling planting tube to perform the seedling planting action regularly, so that the fertilizer seedling planting machine provided by the present invention can plant seedlings at equal intervals, meeting the requirements of various seedling planting intervals.

[0019] Furthermore, a soil-moving gun head is arranged at the seedling outlet of the seedling-transplanting tube, so that the insertion of the seedling-transplanting tube into the ground is more labor-saving and more efficient, and the purpose of removing the soil and releasing the seedlings is achieved, ensuring that the seedlings are normally placed in the soil.

[0020] Furthermore, the present invention provides driving force to the rotating shaft and the driving gear through a power drive device, and the power source of the power drive device can be directly provided by the first wheel. The worker drives the first wheel to rotate by pushing the frame to provide a power source for the transmission mechanism. The present invention saves time and effort and reduces manpower consumption. The power source of the power drive device does not require other complicated devices, and can be directly pushed to complete the functions of trenching, fertilizing and transplanting seedlings. The present invention has low requirements on the place of use and users.

[0021] Furthermore, in the present invention, the rotating shaft is connected to the entire transmission mechanism through a grooved wheel mechanism, and the design of the rotating shaft through the grooved wheel mechanism also realizes equal spacing of fertilizers, thereby achieving the purpose of precise fertilization.

[0022] Furthermore, in the present invention, a second wheel is also arranged on the frame, and the second wheel is controlled to rotate by a gasoline engine, which further reduces the manpower required for fertilization. Only the fertilization direction needs to be adjusted, and the second wheel is driven only by the gasoline engine, so the cost is relatively low, which fully considers the economic level of more farmers. At the same time, the gasoline engine is arranged at the front end of the frame in the propulsion direction, which increases the weight of the front end of the frame in the propulsion direction, so that the furrow opener has higher working efficiency.

[0023] Furthermore, a plurality of arc holes are provided on the inner box body, and the connecting rod of the fertilizer box can be fixed at any position in the arc hole by loosening or tightening the knob, and the position of the fertilizer box in the arc hole is adjusted, thereby changing the contact area between the fertilizer box and the inner box body, and then changing the amount of fertilizer, so that the present invention can not only meet the requirements of equidistant fertilization but also meet the requirements of flexible regulation of the amount of fertilizer.

[0024] Furthermore, in the present invention, a plurality of through holes are provided on the furrow opener, and the through holes cooperate with the pin holes on the frame to achieve the purpose of adjusting the depth of the furrow opener contacting the ground, and the furrowing depth of the furrow opener can be flexibly adjusted.

[0025] Furthermore, the frame of the present invention is also provided with a handle, through which the propulsion direction of the frame can be adjusted. The structure is simple, the cost is low, and various requirements can be met. BRIEF DESCRIPTION OF THE DRAWINGS
