Description

Rice transplanter

Technical field:

The present invention relates to a kind of agricultural machinery, relate in particular to a kind of rice transplanter that is used for.

Background technology:

Along with the development of economy and technology, various agricultural machinery just obtain progressively promotion and application in vast rural area; Yet present widely used rice transplanting machinery exists complex structure, the sowing uniformity mostly and the flatness in land for growing field crops is required defectives such as high, that the field management difficulty is bigger, has restricted popularizing of rice transplanting machinery.

Summary of the invention:

At the above-mentioned defective that exists in the prior art, the present invention aim to provide a kind of simple in structure, light and flexible, tractive force little, carry slotting frequency height, and can avoid rice shoot to leak inserting, the empty rice transplanter of inserting phenomenon.

To achieve these goals, method of the present invention by the following technical solutions: it comprises frame, wheel, main shaft, seedlings sending mechanism, rollover stand, pincers rice seedling distribution mechanism and transmission mechanism; Wheel is installed on the frame by wheel shaft, and main shaft is installed on the frame by eccentric bearing block and support; Described seedlings sending mechanism is made of rack-mounted driven shaft and driving shaft, the conveyer belt that is connected diaxon; Described rollover stand by be fixed on sleeve block, left-hand rotation dish and right-hand rotation dish on the main shaft, be installed in the cycloid mill on the eccentric bearing block, a plurality of bent axles that flexibly connect this mill and right-hand rotation dish, an end are installed in the pincers pipe that the other end on the left-hand rotation dish is sleeved on the bent axle and the base is provided with chute and constitute; Described pincers rice seedling distribution mechanism is provided with the little declutch shift shaft of dialling tongue by being installed in sleeve block, one end is installed in the other end on the sleeve block and is installed in big declutch shift shaft on the left-hand rotation dish, be installed in the shifting block on this big declutch shift shaft, be inserted into the slide bar in the pincers pipe, flexibly connect the folding connecting rod of shifting block and slide bar by bearing pin, be movably connected in the connecting rod between little declutch shift shaft and the big declutch shift shaft, be fixed on opening the pincers block and closing the pincers block on the frame, the one group of chela that is fixed on the slide bar and stretches out from described chute and another group chela that is fixed on the pincers pipe constitute; Described transmission mechanism is by being fixed on hinge wheel on the wheel shaft, being fixed on minor sprocket, rack-mounted jackshaft on the main shaft, being fixed on tightener sprocket on this, being separately fixed at pitch wheel on jackshaft and the driving shaft and the chain that is coiled between above-mentioned three sprocket wheels constitutes; Between rollover stand and seedlings sending mechanism, be provided with and lead rice seedling distribution mechanism, this mechanism by the base be provided with opening be fixed on sleeve pipe on the frame, be inserted into two draw runners in this sleeve pipe, be separately fixed on two draw runners and two groups of from described opening, stretching out lead seedling pincers pin, be fixed on jackshaft be provided with breach and stroke shifting block dial, be installed on the frame and constitute with shift fork that two draw runners flexibly connect.

Below frame, be provided with two Height Adjustable mud that drag; Below frame, be provided with Height Adjustable flat mud cylinder.

Compared with the prior art, the present invention has been owing to adopted the rice seedling distribution mechanism of leading with seedlings sending mechanism interlock, therefore can realize regularly, quantitatively, the location is for seedling, do not limit rice shoot length; Owing to adopted and can make the rollover stand of cycloid motion and on this, be provided with the pincers rice seedling distribution mechanism, the direction that therefore can guarantee chela all the time vertically downward, thereby overcome the easy seedling laying of traditional rice transplanter effectively, float defective such as seedling; In addition, be equipped with and lead the action that rice seedling distribution mechanism can realize simulating the division of labor of left hand and right hand in the transplanting rice seedling by hand process, thoroughly avoided traditional rice transplanter rice shoot root system to be entangled with easily and cause the uneven defective of separating seedlings or planting.The present invention also has can adjust spacing in the rows and line-spacing, and the seedling case is not made advantages such as transverse movement.
