The above-mentioned fertilizer discharge sheaves are respectively installed at the bottom of the fertilizer tank, and coaxially and synchronously move with the driven pulley, the driving pulley is driven by a motor, the tension pulley 1 and tension pulley 2 are hinged with the frame, The oil cylinder performs tension and relaxation operations, and the static mixer is under the fertilizer discharge sheave, and the fertilizer is mixed and then discharged.

In the above-mentioned variable ratio fertilization device with variable ratio and mixed discharge, the motor drives the driving pulley to rotate, and the power is transmitted to the driven pulley through the belt transmission, and then drives the fertilizer discharge sheave to rotate to realize the fertilizer discharge operation and separately control the tension Pulley 1 and tension pulley 2 change the tension of the belt drive and change the equivalent diameter of the driven pulley. The fertilizer discharge groove wheel can be steplessly adjusted in a certain range, and the fertilizer discharge volume can be changed to achieve precise variable ratio. Fertilizer operation.

In the above variable fertilization device with variable ratio and mixed discharge, the driven pulley is composed of a left part, a right part, a pin shaft and a preload spring, and the left part and the right part form crossed V-shaped grooves, and the V-shaped belt is in the V-shaped The power is transmitted in the groove, and the right part can slide freely in the axial direction of the pin shaft. The two ends of the pre-tension spring are respectively connected with the right part of the driven pulley and the pin shaft.

In the variable fertilization device with variable ratio mixed discharge, the static mixer quickly mixes the fertilizers in the fertilizer bin 1, fertilizer bin 2, and fertilizer bin 3 discharged by the fertilizer sheave and then applies them to the ground.

The above-mentioned scheme is only a preferred technical scheme of the present invention, and has the following advantages:

Fertilizer box 1, fertilizer box 2 and fertilizer box 3 are not connected to each other, and different fertilizers are added respectively. By changing the speed of the fertilizer discharge sheave at the bottom of fertilizer box 1 and fertilizer box 3, different ratios of fertilizers are discharged, and a power source is used to change the transmission. Ratio transmission makes the transmission system simple in structure and reliable in performance.

The driven pulley with tensioning mechanism adopts split design, the left part and the right part are staggered with each other, and the equivalent diameter of the pulley can be changed in a large range by changing the distance between the two parts. The tensioning pulley mechanism with hydraulic cylinder is adopted on the one hand. To ensure reliable transmission, on the other hand, the proportional solenoid valve can accurately control the expansion and contraction of the hydraulic cylinder to realize the stepless speed regulation function.

After the three kinds of fertilizers are collected in the static mixer, they collide disorderly and are quickly mixed and then discharged into the ground, so that the fertilizers are fully mixed and can achieve the purpose of near-immediate mixed discharge, providing conditions for precise variable fertilization.

detailed description

The structure of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

In Figures 1, 2, 3 and 4, 1 is the fertilizer sheave, 2 is the fertilizer box 1, 3 is the fertilizer box 2, 4 is the fertilizer box 3, 5 is the frame, 6 is the tension wheel 1, and 7 is the static Mixer, 8 is driving pulley, and 9 is motor, and 10 is tension pulley 2, and 11 is driven pulley, and 12 is left part, and 13 is right part, and 14 is bearing pin, and 15 is preload spring.

Fertilizer box 1 (2), fertilizer box 2 (3) and fertilizer box 3 (4), which are independent of each other, are fixed on the frame (5), and fertilizer sheaves (1) are installed on the bottom, driven by the motor (9) , the driving pulley (8) respectively transmits power to the driven pulley coaxial with the fertilizer discharge sheave (1) to realize the discharge of fertilizer.

Tensioning pulley 1 (6) and tensioning pulley 2 (10) respectively tension the belt drive system of fertilizer tank 1 (2) and fertilizer tank 3 (4). The position of the tensioning pulley can be controlled by using a hydraulic cylinder, and then To change the tension of the transmission belt, the driven pulley adopts a split design, the left part (12) and the right part (13) form a crossed V-shaped groove, and the right part (13) slides freely on the pin shaft (14). The pre-tightening spring (15) adjusts the sliding ability. When the hydraulic oil cylinder is extended, the tension of the belt drive increases, and the right part of the V-belt (13) moves to the right along the pin shaft (14). Tighten the spring (15), the result is that the triangular belt reaches the lower part of the V-shaped groove, the equivalent diameter of the pulley becomes smaller, the rotational speed increases, and the amount of fertilizer discharge increases. On the contrary, when the hydraulic cylinder is controlled to shrink, the tension of the belt transmission decreases, and the pre-set The tight spring (15) restores a certain deformation, forcing the right part (13) to move to the left along the pin shaft (14), realizing the increase of the equivalent diameter of the pulley, the reduction of the speed, and the reduction of the amount of fertilizer discharge, realizing the discharge of fertilizers with different ratios , respectively controlling the tensioning wheel 1 and the tensioning wheel 2 can obtain three kinds of fertilizers with different ratios.

Static mixers (7) are often used in the chemical industry to mix materials. The purpose of mixing is to achieve the purpose of mixing by using random collisions between materials or between the walls of the container. The static mixer (7) is used to combine three The fertilizer discharged from the fertilizer tank is quickly mixed, and then discharged into the soil immediately, realizing the control of fertilizer discharge with less delay and ensuring accurate variable fertilization.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, some improvements and modifications can also be made. These improvements and modifications It should also be regarded as the protection scope of the present invention.
