Description

Intermittent pot seedling diversion conveying device

Technical field:

The utility model relates to the field of agricultural machinery, which is a conveying device for intermittently shunting pot seedlings when transplanting crops.

Background technique:

Dry land pot seedling transplanting machine is one of the key equipments for modern agricultural production at home and abroad. At present, most pot seedling transplanting machines in dry land do not have corresponding pot seedling conveying and feeding devices. Most of the pot seedlings are directly put into the corresponding planter manually, that is, relying on people to move the seedlings from the seedling tray one by one. The seedlings are taken out, and then the seedlings are fed to the planter of the transplanting machine. This method has a large workload and low efficiency; The speed and comfort of operation are also used to realize the mechanism of conveying and feeding seedlings with flexible chain conveying devices. However, since the conveying and feeding devices are mostly driven by a mechanical fixed transmission ratio, the material cylinder is in a moving state when throwing seedlings, and the seedlings in the bowl are fed when throwing seedlings. Due to the impact of falling friction, the position of the seedlings is not accurate enough. It must be equipped with a larger seedling nozzle to guide the seedlings, and a set of conveying and feeding devices usually only provides one seedling hole, which can only provide seedling feeding for one planter, and the utilization rate is low. Low.

Invention content:

The purpose of this utility model is to solve the problem of stopping the material cylinder when throwing seedlings when the seedling feeding device is used to feed the transplanting machine, so as to facilitate the falling of the pot seedlings to an accurate position, and at the same time carry out the seedling dropping operation of double-row shunting. The two planters feed the seedlings at the same time, which greatly improves the utilization rate of the seedling feeding device and reduces a group of seedling feeding devices, simplifies the structure of the pot seedling transplanting machine, reduces the total mass of the machine, and saves manufacturing costs.

The technical solution used in the utility model patent is: an intermittent transmission mechanism, a driving shaft of a conveyor chain, a driven shaft of a conveyor chain, a conveyor chain, a material cylinder, a large bevel gear, a small bevel gear and a bottom plate are installed on the frame, wherein The intermittent transmission mechanism consists of a crank wheel shaft, a sheave shaft, a crank wheel, a sheave wheel, a power input sprocket, and an intermittent mechanism frame. The crank wheel and the power input sprocket are mounted on the crank wheel shaft through a key connection. The key coupling is installed on the grooved wheel shaft, two sprockets are respectively installed on the driven shaft of the conveyor chain and the driving shaft of the conveyor chain, and the conveyor chain with multiple material barrels is surrounded between the sprockets, and the small bevel gear is installed on the conveyor chain. on the chain drive shaft.

Two kinds of valves with different structures are alternately installed under the material barrel, one is a valve without a pin, and the other is a valve with a pin. The blanking opening, the narrow blanking opening is upstream of the sliding valve, its width is slightly larger than the total width of the valve without pin and smaller than the total width of the valve with pin, the wide blanking opening is downstream of the sliding valve, and its width is larger than that of the valve with pin overall width.

The driving force is transmitted to the coaxial crank wheel through the power input sprocket, and the crank wheel meshes with the sheave, so that the sheave and the large bevel gear on the sheave shaft rotate intermittently at the same time, and the large bevel gear and the small bevel on the drive shaft of the conveyor chain The gears mesh, the small bevel gear drives the driving shaft and the sprocket of the conveyor chain, and finally drives the conveyor chain, the material cylinder and the groove wheel for synchronous intermittent motion. The bottom pallet slides intermittently. When passing through the narrow discharge opening, only the valve without pin is freely opened, and the pot seedlings fall through the narrow discharge opening; when passing through the wide discharge opening, both the valve with pin and the valve without pin are opened. At this moment, only the pot seedlings are arranged in the material cylinder with the pin valve, and the pot seedlings fall through the wide blanking opening, thereby realizing the intermittent shunting and conveying of the pot seedlings.

The beneficial effect of the utility model is that the intermittent pot seedling diversion conveying device has a high degree of automation, the material cylinder is in a static state when the seedlings are thrown, the position of the seedlings is accurate, the mechanism is simple, and the operation is reliable, and the diversion of the pot seedlings can be completed by two planters Throwing seedlings, reducing machine input costs, optimizing machine structure, and improving transplanting speed.
