Detailed Description

Other aspects, features and advantages of the present invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, which form a part of this specification, and which illustrate, by way of example, the principles of the invention. In the referenced drawings, the same or similar components in different drawings are denoted by the same reference numerals.

As shown in fig. 1 to 5, the present invention provides an automatic seeding cart, which mainly comprises a cart frame 10, a seed bag 20, a seed conduit 30, wheels 40, and a seeding device inside the wheels, wherein the overall shape of the cart is similar to a trolley, and the cart can be changed by adjusting the direction of the seed conduit 30 when the cart is used for determining whether to push or pull.

The seed bag 20 is fixed on the handcart frame 10, and can be a common cloth bag or a funnel-shaped object made of steel, and the seeds can flow to the seed conduit 30 smoothly only by ensuring. The seed conduit 30 is made of soft or hard materials, but needs to be smooth, and the seed conduit 30 is communicated with the bottom of the seed bag 20, so that seeds can flow to the seeding device on the inner side of the wheel 40 along the seed conduit 30. The stroller frame 10 itself is not particularly limited, and a common person can hold the handle to use the stroller comfortably, but only requires that the cross member 11 of the stroller frame 10, below which the wheel axles of the wheels 40 are fixed, is hollow so that the wheel axle connecting the two wheels 40 can pass through. The cross member 11 is relatively rotated with the wheel shaft, wherein the wheel 40 is rotated with the wheel shaft while rolling forward, and the cross member 11 integrated with the frame is not moved. The cross beam 11 is integrated with the frame and pushed by the operator, and the wheel shaft inside the hollow rotates to provide power for the sowing bar 60.

Meanwhile, fixing pull rings 70 capable of restricting the movement of the sowing bar 60 in the up and down direction are provided under both sides of the cross member 11 of the cart frame 10. The wheel 40 is provided with a circular groove 41 for providing a position for fixing the pull ring 70 on the frame, namely the circular groove 41 is coaxially arranged with the wheel 40, the axis of the inner side surface of the wheel 40 is provided with a raised pendulum-hammer-shaped cam 80 which is hinged with a connecting rod 90, and the other end of the connecting rod 90 is hinged with the seeding rod 60. The horizontal portion of the fixing tab 70 is inserted into the circular groove 41 after passing through the strip-shaped groove of the sowing bar 60. The fixing pull ring 70 and the circular groove 41 form a limiting mechanism to limit the vertical reciprocating motion of the sowing bar 60.

The sowing bar 60 is shaped like an inverted numeral 7 and is provided to push seeds falling to the ground through the seed guide 30 into the ground for sowing. The sowing bar 60 can only vertically reciprocate because of being fixed by the fixing pull ring 70 on the cross beam 11 of the frame, so that the operation of pushing seeds into the ground can be realized on soft farmlands plowed.

As shown in fig. 4, the outlet of the bottom end of the seed guide tube 30 faces the sowing bar 60 and is spaced from the sowing bar 60 by less than a diameter of one seed, and since the sowing bar 60 has a certain length and reciprocates, the outlet of the seed guide tube 30 is periodically exposed, so that a certain amount of seeds can be periodically discharged, and the certain amount of discharge can be determined by adjusting the length of the connecting rod 90 and the position of the seed guide tube 30. The effect of planting a plurality of seeds at regular intervals during sowing can be realized by the seeds flowing out at intervals.

The sowing interval time and the quantity of seeds flowing out of the seed guide pipe 30 can be adjusted by adjusting the size of the wheels 40, the connecting rod 90 and the sowing rod 60 or adjusting the position of the outlet of the seed guide pipe 30.

The operation of the automatic seeding cart according to the invention will now be briefly described with reference to fig. 1 to 5, in combination with the above description of the constructive technical features:

an operator holds the handle on the frame and pushes the trolley to move forwards, wherein the hollow cross beam 11 below the frame is fixed relative to the operator, and the wheel shaft on the inner side rotates due to the rotation of the wheels 40.

The wheel rotates, drive inboard connecting rod 90 through pendulum shape cam 80 and rotate, connecting rod 90 drives the motion of seeding pole 60, because seeding pole 60 is restricted by fixed pull ring 70 and can only carry out vertical direction's reciprocating motion, therefore, seeding pole 60 carries out reciprocating motion when wheel 40 rotates, the periodic export that exposes seed pipe 30, therefore the inside seed of the periodic outflow of export of seed pipe 30, then the underground is impressed by the seeding pole 60 of rear, accomplish the seeding.

After the seeds flow out of the outlet of the seed guide 30, the raised sowing bar 60 is again dropped by the rotation of the wheel 40, and thus the outlet of the seed guide 30 is closed and opened again after a distance, and the seeds are sown again by the sowing bar 60.

If necessary, the shape of the wheel tyre or the lines of the tyre can be changed, and the friction force can be increased. The condition that the trolley wheel does not rotate is avoided.

While the foregoing is directed to the preferred embodiment of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
