Detailed Description

The technical contents of the preferred embodiments of the present invention will be more clearly understood and appreciated by referring to the drawings attached to the specification. The present invention may be embodied in many different forms of embodiments, and the scope of the invention is not limited to the embodiments described herein.

As shown in fig. 1, in an embodiment according to the present invention, the under soil fertilization system 100 is suspended and towed by a towing system, such as a high horsepower towing tractor 200, and provides a power source, while liquid manure from a manure pit is pumped to the under soil fertilization system 100 through a towing hose 300. During operation, install fertilization system under soil 100 behind tractor 200 and hang the suspension and carry fertilization system under soil 100 to arable land or meadow limit by tractor 200, pull hose 300 one end and be connected to fertilization system under soil 100, will pull the other end of hose 300 and be connected with the setting at the dirty pond of excrement by the rotor pump, carry fertilization system under soil 100 with liquid fertilizer. A driver controls the liquid fertilizer distributor 110 to operate at the tractor 200, and simultaneously lowers the under-soil fertilization system 100 to the required depth through the rear suspension lifting function, and starts ditching fertilization operation of 50-100mm under the soil for cultivated land and grassland.

Fig. 2 is a schematic view of the main frame structure of the under soil fertilization system 100 when the liquid fertilizer distribution hose is not shown, and referring to fig. 3 and 4 when the liquid fertilizer distribution hose is shown, it can be seen that the main frame structure includes a middle frame structure 101, a left side frame structure 102, and a right side frame structure 103. A row of ditching ploughshares 107 is arranged below the main body frame structure. The ditching ploughshare 107 is preferably made of 65Mn spring steel, so that when firm sundries such as stones in soil are encountered during the operation of farmland or grasslands, the ditching ploughshare 107 can avoid the firm sundries through the spring steel elasticity principle so as to avoid damage. A soil crushing roller 105 is also provided behind the middle frame structure 101, and the left and right side frame structures 102, 103. The soil crushing roller 105 is mounted on the main frame structure of the under soil fertilization system 100 by a pressing spring 106. During operation, after the ditching ploughshare 107 ditches, the ditched soil is fertilized through the liquid fertilizer distribution hose 108, and then the soil crushing roller 105 crushes and seals the soil turned up by the ploughshare 107, so that the liquid fertilizer is isolated from the air, and nutrition volatilization is avoided. The soil crushing roller 105 can move up and down along with the soil terrain through the pressure spring 106, and the soil sealing effect is guaranteed. The left side frame structure 102 and the right side frame structure 103 can be folded left and right to open and retract under the drive of the hydraulic cylinder 104. The compression spring 106 also allows the soil crushing roller 105 behind the left side frame structure 102 and the right side frame structure 103 to have a certain degree of freedom in the height direction, and to be retracted together with the left side frame structure 102 and the right side frame structure 103. The driver can stow the left and right side frame structures 102, 103 during transport, reducing the overall width of the under soil fertilization system 100, thereby achieving better throughput.

The trailing hose 300 is connected to the rigid swing pipe 131 by a swivel joint 132. The rigid swing pipe 131 is connected to a distributor inlet pipe 134 by a swivel joint 133. The distributor inlet pipe 134 is connected with the liquid fertilizer inlet 112 of the liquid fertilizer distributor 110. The liquid manure from the manure pit can be delivered to the liquid manure distributor 110 through the above-mentioned pipe connections. A roller base 137 is provided on the middle frame structure 101. The rigid swing pipe 131 is connected to the roller base 137 through the tension wire 135 and the tension device 136, so that the rigid swing pipe 131 can swing at a certain angle, such as 90 degrees, to prevent the hose from being scraped by other mechanisms during a work turn. Drag hose 300 and drag the in-process winding and folding to appear in ploughing and meadow long distance and turn many times, cause the hose jam, can eliminate the hose winding and the folding that appear in the work through installation rotary joint 132, 133. By adjusting the tensioning device 136, the tension of the tensioning steel wire 135 can be adjusted, the pipeline connection strength is ensured, and the fertilization efficiency is ensured.

As shown in fig. 5, the liquid fertilizer dispenser 110 includes a dispenser housing 111. The distributor shell 111 is provided with a liquid fertilizer inlet 112, a multi-path liquid fertilizer outlet 113, a hydraulic motor 114, an exhaust hole 115 and an access cover plate 118. Liquid fertilizer is pumped into the liquid fertilizer distributor 110 from the liquid fertilizer inlet 112 through the distributor inlet pipe 134 by the impeller 117 driven by the hydraulic motor 114. The impeller 117 is provided with a cutter which can cut impurities (crop straws and soil blocks) in the manure during rotation to prevent the liquid manure from blocking the outlet. The bottom in the distributor shell 111 is also provided with a weight settling chamber 116, when a metal weight enters the inner cavity of the distributor, the metal weight can automatically fall into the weight settling chamber 116 due to self gravity, and the metal weight is manually discharged after operation is completed, so that the impeller in the inner cavity of the distributor is prevented from being influenced. The multiple liquid fertilizer outlets 113 are preferably 24 paths and are evenly distributed on two sides of the distributor housing 111, and the liquid fertilizer is distributed to the ditching ploughshares 107 on the left and right frame structures 102 and 103 through liquid fertilizer distribution hoses 108 connected to the multiple liquid fertilizer outlets 113. All mechanisms in the liquid fertilizer distributor 110 adopt galvanization treatment, so that the distributor is prevented from being corroded by manure, and the service life is prolonged.

As shown in fig. 6, in a preferred embodiment, a liquid fertilizer filter 120 is further installed before the liquid fertilizer distributor 110.

Referring to fig. 7-11, liquid fertilizer filter 120 includes a filter housing 121. The filter case 121 is provided at front and rear sides thereof with a filter inlet 127 and a filter outlet 128, respectively, and at left and right sides thereof with L-shaped screen turnover guide grooves 125. A turnover type filter screen box is arranged in the filter box body 121. The flip-flop screen box includes a screen box upper half 122 and a screen box lower half 124, and a hinge 123 connecting the screen box upper half 122 and the screen box lower half 124. The opening of the filter cartridge faces the side of the filter inlet 127 of the filter case 121. The turning guide shafts 125 are provided at the left and right sides of the turning filter screen case. The tumble guide shaft 125 is fitted in the tumble guide groove 125 to be movable in the tumble guide groove 125.

A screen cartridge inversion drive mechanism 129 is provided atop the filter housing 121. The screen cartridge invert drive mechanism 129 is driven by a hydraulic motor 1291. The hydraulic motor 1291 drives a driven gear 1293 via a drive gear 1292. Further, the driving gear 1292 and the driven gear 1293 respectively drive the synchronous pulley 1294 through the synchronous belt 1295. The synchronous belt wheel 1294 drives the driving steel coils 1296 at two sides to perform coiling and uncoiling actions. One end of the driving steel coil 1296 is connected to the turning guide shaft 125 of the filter screen box, and the turning guide shaft 125 can be driven to move in the turning guide groove 125, so as to drive the turning filter screen box to turn.

Liquid fertilizer is when the fertile filter 120 of process liquid, and debris are filtered and are persisted in the box body space of convertible filter screen box, when needs are cleared up convertible filter screen box, accessible filter screen box upset actuating mechanism 129 overturns convertible filter screen box, emptys the interior debris of box.
