Description

Two-wheel drive fertilizer plow

The utility model belongs to agricultural machinery, in particular to a plow combined with a fertilizer applicator dragged by an agricultural tractor.

The traditional fertilization method is artificial fertilization, and its labor load is very large. For this reason, some manufacturers have introduced a plow with a fertilizer applicator on the plow frame, but the fertilization effect of this plow is not ideal. The reason is that : The fertilizing shaft of the fertilizer applicator is dragged by the walking wheel arranged at the bottom of the front side of the plow frame, but the contact between the walking wheel and the ground is not good when plowing the ground, and it is often in a suspended state or due to the resistance of a large clod And stop rotating, cause the fertilizer dial shaft not to turn and stop fertilizer discharge, cause fertilization to be discontinuous, uneven. Peasants are generally looking forward to the appearance of a kind of agricultural plow that can truly realize continuous and uniform mobile fertilization.

The purpose of the utility model is to provide a motorized agricultural plow with a fertilizer applicator, which can fertilize evenly and continuously.

The utility model is realized in the following way: the two-wheel drive fertilizing plow includes a plow frame, a fertilizer box installed above the front end of the plow frame, a plow leg and a plow share installed at the lower part of the plow frame, and a plow mounted on the bottom side of the front end of the plow frame through splints. The walking wheel and the walking gear coaxial with the walking wheel, and the side of the fertilizer box is equipped with a fertilizer dialing gear installed on the fertilizer shaft of the fertilizer box. The auxiliary wheel and the auxiliary gear are coaxially installed on the shaft. The plow frame above the shaft is equipped with a spring rod that can move up and down. The lower end of the spring rod is connected to the shaft. Gear and walking gear are connected on the fertilizer dialing gear.

The fertilizer applicator on the agricultural plow of the utility model is driven by the walking wheel instead of the additional auxiliary wheel and the driving wheel. The tension effect of the spring rod on the connecting plate keeps the auxiliary wheel in contact with the ground, thereby ensuring its rotation and ensuring The fertilizer shaft works reliably. Therefore, the utility model realizes continuous and even fertilization, completes the design purpose, and its structure is simple, reliable and easy to realize.

Accompanying drawing is the structural representation of the embodiment of the utility model.

Below in conjunction with accompanying drawing, the utility model is further described. Embodiment is the agricultural plow that is articulated with the small four-wheels of agriculture, and its plow frame 1, plow leg 3, plow share 4, splint 5, traveling wheel 6 and traveling gear 7 are the same as the common four-wheel drag agricultural fertilizing plow, and the fertilizer box The side of 2 is equipped with the fertilization gear 8 that is connected with the fertilizer shaft, the auxiliary wheel 11 and the auxiliary gear 12 are installed on the connecting plate 9 through the shaft 10, and the spring 14 that is nested on the spring bar 13 and is in a compressed state always keeps the connection The downward force of the plate 9 makes the auxiliary wheel 11 reliably ground. During plowing, the auxiliary gear 12 and the travel gear 7 jointly drive the fertilizer setting gear 8 through the transmission chain 15, thereby ensuring that the fertilizer setting gear works reliably. In order to make the amount of fertilizer application adjustable, in the embodiment, the fertilizer box 2 is hinged with a swing frame 16, the swing frame 16 is connected with a curved plate 17, and the end of the curved plate 17 stretches into the bottom of the fertilizer box 2 to seal the fertilizer box 2 The fertilizer outlet at the bottom, the swing frame 16 is also connected with a control handle 18 that can rotate the swing frame 16, and the control handle 18 is provided with a plurality of tooth-shaped gaps 19, and is also provided with a fertilizer row corresponding to each tooth-shaped gap 19. Measure the scale line 20, the fertilizer box 2 is also equipped with a hanging rod 21 that can be stuck on the tooth-shaped gap 19. During fertilization, the swing frame 16 can be pulled forward or backward by the control handle 18, thereby adjusting the sealing area of the curved plate 17 to the fertilizer discharge port at the bottom of the fertilizer box 2, and the tooth-shaped gap 19 is stuck on the hanging rod 21, corresponding to The scale line 20 indicates the amount of fertilizer discharge. In the embodiment, a deep cultivator is placed on the plowshare, and the end of the deep tiller in contact with the ground is in the shape of a sharp tooth, and the tip of the tooth extends downward beyond the bottom of the plowshare. The effect of deep cultivator 22 is to open the furrow deeper than the land plowed by a ploughshare 4, so that when it rains or waters the ground, water can flush the fertilizer applied in this furrow without loss.
