The purpose of the present invention is to make up for the defects of the prior art, and to provide a subsoiling fertilizer applicator, which belongs to the technical scope of conservation tillage, and is mainly suitable for subsoiling the soil at intervals to fertilize the soil and also has the function of removing stubble.

The present invention is achieved through the following technical solutions:

A subsoiling fertilizer applicator, characterized in that it includes a frame, a stubble cutter mechanism is installed at the bottom of the front side of the frame, the stubble cutter mechanism includes a stubble cutter shaft that is rotatably installed under the front part of the frame, and the stubble cutter shaft There are several stubble knives arranged in a double-helix arrangement on the top of the frame; the bottom of the frame is located behind the stubble knife mechanism and a deep loosening shovel mechanism is installed; Ditching mechanism, the ditching mechanism includes ditching knife tubes arranged longitudinally, the bottoms of the ditching knife tubes are equipped with ditching knives, and the fertilizer outlet on the fertilizer applicator mechanism communicates with the upper mouth of the corresponding ditching knife tubes.

A subsoiling fertilizer applicator, characterized in that: a motor and a gearbox connected to the motor are installed on the top of the front side of the frame; the output shaft of the gearbox is connected to the stubble cutter shaft through a belt pulley mechanism.

A subsoiling fertilizer applicator, characterized in that: a rotary tiller mechanism is installed at the bottom of the frame corresponding to the blade in the subsoiling shovel mechanism, and the output shaft of the gearbox is connected to the rotary tiller shaft of the rotary tiller mechanism. Drive connection through chain transmission mechanism.

A subsoiling fertilizer applicator, characterized in that: the tail of the frame is located behind the ditching mechanism and is rotatably installed with a pressing roller.

A subsoiling fertilizer applicator, characterized in that: the fertilizer applicator mechanism is equipped with an electric device that provides power for it.

The working performance of the present invention requires:

(1) The stubble cutters of the working part of the subsoiling fertilizer applicator are arranged on the stubble cutter shaft in a double helix arrangement. At the same time, the diameter of the cutter shaft is appropriately increased in design. During the operation, it can reduce the vibration and improve the stubble removal effect at the same time;

(2) The front of the subsoiling fertilizer applicator adopts a suspension connection device, and the general three-point suspension method is suitable for connection with most tractors;

(3) The subsoiling blade tip and ditching mechanism of the subsoiling fertilizer applicator adopt a series of processing techniques such as quenching, tempering and quenching, so that the cultivating knife can also have a good deep soil loosening effect on relatively hard soil. At the same time, the depth of soil loosening can be adjusted.

(4) The subsoiling fertilizer applicator should have sufficient lateral and longitudinal stability when walking on the ground, and good passability on uneven road surfaces;

(5) The subsoiling fertilizer applicator has high reliability and is easy to operate.

(6) The soil before the subsoiling operation is relatively hard, and it is difficult for the subsoiler to enter the soil, and the traction force is large, so it needs to be matched with a high-power tractor.

(7) Determine the tractor power matching according to the soil quality, soil moisture content, subsoiling depth, and subsoiling width.

The suspension connection device is fixed and hinged on the frame, the tractor power is input through the transmission device, and the transmission device is fixed on the frame and connected with the small V-belt pulley through the V-pulley transmission shaft, and is connected with the sprocket transmission shaft at the same time. The large V pulley is connected with the small V pulley through a belt. The large V-belt wheel is connected with the stubble cutter mechanism, the small sprocket is connected with the electric device, and the small sprocket is connected with the large sprocket through a chain. The tensioning pulley is installed on the left side of the frame. The present invention is mainly used for the matching operation of the dragging machine and is mainly used for the stubble removal and crushing of the low-thin stalks such as wheat upright in the field or the crop stalks placed in the field with the stubble cutter mechanism (because this model belongs to the horizontal machine). The crushed stalks are naturally spread evenly, and the crushed stalks are used as fertilizer to be applied back to the ground after plowing. At the same time, the fertilizer applicator, subsoiling shovel mechanism, and rotary tiller mechanism (not shown in the figure) cooperate to complete the deep plowing of the compacted soil, and use the ditching mechanism to excavate the soil while the fertilizer falls along the ditching pipe. into the soil, and then the compaction roller (not shown in the figure) performs land leveling and compaction on the soil. Complete stubble removal and land plowing and fertilization at one time. The use of the whole machine not only further improves the fertility of the soil, but also prevents environmental pollution (farmers burn straw), and improves the scope of land use (suitable for severely compacted and low-efficiency soil).

When the implement is working, the implement advances at a constant speed under the action of tractor traction. The power transmitted by the power output shaft of the tractor is connected by a spline and directly transmitted to the transmission device of the machine. The transmission device transmits the power to the transmission shaft of the V pulley and the sprocket respectively. Drive shaft; the small V pulley transmits power to the large V pulley through three belts, and the large V pulley drives the shaft of the stubble cutter mechanism to rotate. As the tractor starts and moves forward, the implement slowly lands, and the stubble cutter mechanism rotates, and the moving knife will Touch the stalk first to make it fall forward. Then the rotating moving knife cuts off the stalk from the root and throws the stalk forward. Under the restriction of the fixed knife bed, the stalk is turned to the horizontal moving knife to work again. At this time, the forward-leaning stalks are blocked by the unharvested stalks ahead, and as the machine advances, the stalks enter the casing and are further crushed under the repeated action of the stubble cutter mechanism, and then evenly sprinkle the crushed stalks to the field. At the same time, the subsoiling shovel mechanism gradually enters the predetermined depth of the soil by the weight of the machine tool to destroy the formed compaction layer and loosen the soil. The sprocket drive shaft drives the chain drive shaft and the sprocket drives the rotary blade mechanism to rotate through the chain, and the rotary blade mechanism The soil turned up by the subsoiling shovel mechanism is further plowed so that the soil reaches a state suitable for fertilization. The electric device of the fertilization rack assembly provides power to the small sprocket, and the small sprocket transmits the power to the large sprocket through the connecting chain. It falls into the groove opened by the ditching mechanism, and then the soil is leveled and pressed by the compaction roller to complete the fertilization operation.

The advantages of the present invention are:

(1) The tractor and the subsoiling fertilizer applicator should be properly matched to ensure sufficient work efficiency, maximize power utilization, reduce fuel consumption, and reduce work costs;

(2) The power transmission system is simple and reliable, suitable for mass production and easy to maintain;

(3) The whole machine is sturdy and durable, compact in structure, light in weight, saves raw material consumption and reduces manufacturing costs;

(4) The power part is convenient for comprehensive utilization;

(5) The ditching mechanism should have sufficient ability to penetrate into the soil, and should be able to open a seed ditch on uncultivated land that is conducive to the growth and development of seeds and crop roots. little resistance.

(6) Subsoiling operation is one of the technical contents of conservation tillage. Conservation tillage requires straw and stubble to cover the ground surface. For this reason, the working parts (subsoiler shovel mechanism) are required to have good passing performance without being entangled by weeds.

(7) The subsoiler is required to have the performance of ensuring that it loosens the soil without crushing the soil or destroying the structure of the plow layer.
