Detailed Description

As shown in figures 1 to 7, the utility model mainly comprises a tractor, a fertilizing unit and a rotary tillage unit, and the utility model is described in detail with the attached drawings.

As shown in fig. 1 to 2, the fertilizing unit mainly includes a fertilizing frame 1, the fertilizing frame is a metal welded component, the fertilizing frame is rectangular as a whole, a first ear plate 11 is disposed on a left side wall of the fertilizing frame, a second ear plate 12 is disposed on a right side wall of the fertilizing frame, a wheel frame 15 is disposed at the bottom of the fertilizing frame, a first traveling wheel 13 is rotatably mounted on the wheel frame through a wheel shaft 77, a pair of third ear plates 14 is further fixed on the right side wall of the fertilizing frame, and the two third ear plates are respectively located at the front side and the rear side of the second ear plate. Grooves 16 are arranged on the front side wall and the rear side wall of the fertilizing frame.

A fertilizer box 2 is fixed on the top of the fertilizer applying frame, as shown in fig. 3, the fertilizer box is of a cuboid structure, the top of the fertilizer box is open, and a box cover can be arranged on the top of the fertilizer box. The lower surface of the inner cavity of the fertilizer box is an inclined surface 22, so that granular fertilizer can slide down along the inclined surface. The bottom of the fertilizer box is provided with a fertilizer falling hole 21, and the fertilizer in the fertilizer box can pass through the fertilizer falling hole and move out of the fertilizer box. The center of the fertilizing frame is provided with a mounting hole, a mixing box 3 is fixed in the mounting hole, as shown in fig. 4 and 5, the mixing box 3 is of a funnel-shaped structure, the upper end of the mixing box is large, the lower end of the mixing box is small, and the upper surface of the mixing box and the upper surface of the fertilizing frame are arranged in a coplanar manner. The fertilizer in the fertilizer is directly dropped into the mixing box after passing through the fertilizer dropping hole. A partition plate 32 is arranged on the inner side of the mixing box, the partition plate is of a cross-shaped structure, and the side wall of the partition plate is fixedly contacted with the inner wall of the mixing box. The inner cavity of the mixing box is divided into four mutually independent cavities by the partition board, the four cavities are in one-to-one correspondence with the four fertilizer boxes, and the fertilizer in the fertilizer boxes falls into the corresponding cavities. The fertilizer falling holes are communicated with the four cavities, and the chemical fertilizers in the four cavities fall into the fertilizer falling holes simultaneously.

In order to apply the fertilizer, a spreading mechanism is arranged below the mixing box, as shown in fig. 7, the spreading mechanism comprises a driving gear 76 fixed on a gear shaft, a driven gear 75 engaged with the driving gear, a support rod 75 fixed on a wheel carrier, and a support block 73 fixed between the two support rods, the gear shaft 72 of the driven gear is rotatably connected with the support block, a circular drive plate 7 is fixed at the top of the gear shaft, four drive plates 71 are fixed at the top of the drive plate, the drive plates are arranged in a cross shape, and the drive plates are in a strip shape. Chemical fertilizer in the mixing box passes through the play fertile hole 31 of mixing box bottom and falls on the driver plate, and the driver plate is at rotatory in-process, dials the effect that board, driver plate play the striking to the chemical fertilizer granule, and the chemical fertilizer sputters to around under the striking effect, and wherein most chemical fertilizers sputter to the front side of driver plate, left side and rear side, and the chemical fertilizer that sputters away falls subaerial, and then has realized fertilization work.

When in use, different fertilizers, such as urea, nitrogen fertilizer, compound fertilizer and the like are added into different fertilizer boxes. Thus, different fertilizers can be uniformly spread on the ground through the fertilizing unit. Because the driving plate rotates synchronously when the first traveling wheel rotates, the fertilizer is spread while the driving plate rotates.

In order to control the opening and closing of the fertilizer dropping hole, the mixing proportion of various fertilizers is adjusted according to the requirement. An adjusting mechanism is arranged in the bottom of the fertilizer box. As shown in FIG. 6, the adjusting mechanism comprises an adjusting screw 6 rotatably mounted in the bottom of the fertilizer box, a screw nut 61 engaged with the adjusting screw, a baffle plate 62 fixed on the screw nut, a handle 64 slidably arranged on the adjusting screw, and a crank 65 fixed on the handle, wherein the handle and the adjusting screw are relatively fixed along the circumferential direction, so that the handle and the adjusting screw can rotate synchronously. A limiting plate is fixed at the tail end of the adjusting screw rod to prevent the adjusting screw rod from being separated from the handle. When the rocking handle is rotated, the handle can be driven to rotate. And then drive the rotation of adjusting the lead screw, and then drive lead screw nut's removal, be equipped with two round holes 63 of size on the baffle, after the round hole of equidimension not and the hole intercommunication that falls the fertilizer, the flow that the chemical fertilizer shifted out the fertilizer case is different. Further, the fertilizer mixing with different proportions is realized. The proportion of the fertilizer moving out of the fertilizer box is adjusted through the adjusting mechanism. The handle and the rocking handle are both arranged in the groove.

The rotary tillage unit mainly comprises a rotary tillage frame 4, a second walking wheel 41 is arranged on the rotary tillage frame, a fourth ear plate 42 is fixed on the rotary tillage frame, and a hinge shaft is arranged between the second ear plate and the fourth ear plate so as to realize the assembly of the fertilization unit and the rotary tillage unit. And two auxiliary rods 5 are arranged between the third ear plate and the rotary tillage frame, the two auxiliary rods are in a splayed structure, and the auxiliary rods can be extended and also can be shortened. The auxiliary rod comprises a first rod and a second rod, the first rod and the second rod are connected in a sliding mode, and a spring is arranged between the first rod and the second rod. When the fertilizing frame turns, the rotary tillage frame turns along with the fertilizing frame, one auxiliary rod extends, and the other auxiliary rod shortens. When the rotary tillage frame returns to the straight line walking, the auxiliary rod is reset.

When only fertilization is needed, the rotary tillage unit is separated from the rotary tillage unit; when only fertilization is needed, the rotary tillage unit is installed with the tractor; when the fertilizer is needed to be applied and the rotary tillage is needed, the fertilizer applying unit and the fertilizer applying unit are sequentially connected with the tractor.
