Detailed Description

As shown in fig. 1 to 3, the present invention mainly comprises a frame 1, a fertilizing unit and a fertilizer box 38, and the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1, a frame 1 is a basic component of the present invention, the frame is a profile welded component, a wheel carrier 11 is fixed at the bottom of the frame, a traveling wheel 12 is rotatably mounted on the wheel carrier, and four traveling wheels are provided, including two at the front end and two at the rear end. The frame is provided with a walking driving mechanism which drives the walking wheels to walk.

The front end of the rack is provided with a fertilizing unit, as shown in fig. 2, the fertilizing unit comprises a vertical rod 2 fixed at the bottom of the rack and vertically arranged, a first ear plate 21 fixed on the vertical rod, a fertilizing pipe 3 arranged in parallel with the vertical rod, a second ear plate 31 fixed on the fertilizing pipe, a swing rod 22 arranged between the first ear plate and the corresponding second ear plate, a connecting rod 4 hinged with the swing rod below through a hinge shaft 41, a crank 42 hinged with the connecting rod, a driven sprocket 43 rotatably installed at the bottom of the vertical rod, a driving sprocket 44 coaxially arranged with a walking wheel at the front side of the rack, a chain 45 arranged between the driving sprocket and the driven sprocket, and the driven sprocket and the crank are fixedly connected. In the rotating process of the travelling wheel, the driving chain wheel can drive the driven chain wheel to rotate, and then the crank is driven to rotate. And then the connecting rod drives the oscillating bar to reciprocate in the vertical plane, so as to drive the fertilizing tube to move up and down, and the fertilizing tube also moves in the horizontal direction in the process of moving up and down. The fertilizing tube, the swing rod and the vertical rod form a parallelogram link mechanism, the crank, the connecting rod, the vertical rod and the swing rod form a crank link mechanism, and the driving chain wheel, the chain, the driven chain wheel, the crank and the connecting rod form a driving mechanism for driving the swing rod to swing in a reciprocating mode in a vertical plane.

As shown in fig. 3, the fertilizing tube is a metal tube, the upper end of the fertilizing tube is connected with a fertilizer box 38 arranged at the top of the frame through a hose 32, a fixing ring 35 is fixed in the inner cavity of the fertilizing tube, a fixing cylinder 33 fixed on the inner wall of the fertilizing tube is arranged below the fixing ring, the fixing cylinder is of a cylindrical structure, the upper surface of the fixing cylinder is a conical surface 331, a baffle plate 34 is arranged between the fixing cylinder and the fixing ring, the baffle plate is of a truncated cone-shaped structure, the upper end of the baffle plate is large, the lower end of the baffle plate is small, a spring is arranged between the baffle plate and the fixing ring, and the conical side wall of the baffle plate. The closing of the upper end and the lower end of the fertilizing tube is realized through the baffle plate, the conical crushing block 341 is fixed at the top of the baffle plate, the tip of the crushing block faces upwards, and the crushing block is used for crushing the massive fertilizer. The bottom of the baffle is fixed with a cylindrical pressure lever 37, the lower end of the pressure lever is a conical part 371, and the outer diameter of the pressure lever is smaller than the inner diameter of the fixed cylinder. When the travelling wheels travel in the field, the fertilizing unit can drive the fertilizing pipe to move up and down, when the fertilizing pipe moves down and contacts with the ground, the fertilizing pipe moves down continuously, overcomes the action force of the spring and jacks up the baffle plate through the pressure rod, and at the moment, fertilizer in the fertilizing pipe falls through a gap between the baffle plate and the inner wall of the fertilizing pipe and then sequentially passes through the inner cavity of the fixed cylinder and a gap between the pressure rod and the inner wall of the fertilizing pipe; along with the rotation of walking wheel, when the fertilization pipe moved up, the baffle resets under the effect of spring, and after the baffle contacted with fixed cylinder top, the upper portion and the lower part of fertilization pipe no longer communicate, and the chemical fertilizer restriction is in fixed cylinder. Therefore, the fertilizing tube moves downwards once every time the travelling wheel rotates for a circle, and then the fertilizing is performed once.

According to the fertilizer applicator, the fertilizing mechanism acts once every time the travelling wheels rotate for a circle along with the travelling of the rack, so that one fertilizing action is realized. The invention has simple structure, realizes fertilization without additional power and is convenient to maintain.
