Description

Technical Field

[0001] The invention relates to a fast-forward device of a hydraulic fertilizer pushing mechanism and belongs to the field of agricultural machinery. Background Art

[0002] Fertilization refers to the agricultural technical measures of applying fertilizer to the soil or spraying it on plants to provide the nutrients needed by plants and maintain and improve soil fertility. The main purpose of fertilization is to increase crop yields, improve crop quality, improve soil fertility and improve economic benefits. Therefore, reasonable and scientific fertilization is one of the main means to ensure food security and maintain sustainable agricultural development. The main basis for fertilization is soil fertility level, crop type, target yield, climate environment and fertilizer characteristics, so as to select appropriate fertilizers, estimate the required fertilizer dosage, and determine the fertilization time and fertilization mode. According to the different fertilization time, it can be divided into base fertilizer and topdressing. According to the different fertilization modes, it can be divided into broadcasting, flushing, hole application, strip application, etc.; broadcasting and flushing are conducive to the diffusion of nutrients and are easy to apply, but the nutrient loss is large and the utilization rate is low; hole application and strip application have less nutrient loss and high utilization rate, but consume a certain amount of mechanical energy; with the development of modern precision agriculture, precision fertilization has also developed rapidly and will become an important fertilization mode;

[0003] In the actual operation of the hydraulic push-type organic fertilizer spreader, when loading organic fertilizer, the fertilizer will fall freely and there will be a phenomenon of accumulation with high in the middle and low around, which will make the gap between the front and back of the fertilizer box larger. When pushing and spreading the fertilizer, there will be a phenomenon of no material or little material being spread, which will make the amount of fertilizer applied to the land uneven and affect the overall fertilization effect of the land.

[0004] Therefore, in order to solve this phenomenon and improve the fertilization efficiency, there is an urgent need for a mechanism that can achieve fast-forward operation by adjusting the hydraulic valve body to solve the above problems. Summary of the invention

[0005] The present invention solves the problem that when the existing organic fertilizer spreader is loaded with organic fertilizer, a large gap appears in front and behind the fertilizer box. When the fertilizer pushing mechanism is fertilizing, the fertilizer in the fertilizer box is uneven, and there will be a phenomenon of accumulation of no material or little material when fertilizing, resulting in uneven fertilization of the whole land, affecting the overall fertilization effect of the land. In view of the shortcomings of the prior art, the present invention discloses "a fast-forward device of a hydraulic fertilizer pushing mechanism".

However, it should be understood that these descriptions are exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0022] Specific implementation method 1: Combination Figure 1-Figure 3 Description of the present embodiment. A fast-forward device of a hydraulic fertilizer pushing mechanism of the present embodiment comprises a fertilizer pushing mechanism 1, a guide rail 2, a pulley 3, a guide actuator 4, a pull rod 5, a hydraulic valve body 6, a hydraulic valve rotating core 7 and an actuator rod 9. The guide rail 2 is fixedly mounted on the fertilizer pushing mechanism 1, the pulley 3 is rotatably mounted on the guide actuator 4, a pull rod 5 is mounted on the other end of the guide actuator 4, the other end of the pull rod 5 is fixedly connected to the actuator 9, a hydraulic valve rotating core 7 is mounted on the hydraulic valve body 6, the actuator rod 9 is fixedly mounted on the hydraulic valve rotating core 7, the fertilizer pushing mechanism 1 is fixedly connected to the hydraulic mechanism, the hydraulic mechanism is an existing hydraulic push rod, the hydraulic valve body 6 is connected to the hydraulic mechanism to control the thrust of the night pressing mechanism, and the hydraulic mechanism The work drives the fertilizer pushing mechanism 1 forward, and the output end of the fertilizer pushing mechanism 1 is installed in the fertilizer box 14. The output end of the fertilizer pushing mechanism 1 contacts the fertilizer 15 in the fertilizer box 14 and pushes the fertilizer forward. In the process of pushing the fertilizer pushing mechanism 1 forward, the guide rail 2 on the fertilizer pushing mechanism 1 contacts the pulley 3, and the pulley 3 rotates and moves at an angle under the influence of the guide rail 2. The pulley 3 pulls the pull rod 5 through the guide actuator 4, and the pull rod 5 is forced to pull the actuator rod 9. The actuator rod 9 is mounted on the hydraulic valve rotating core 7. Therefore, when the actuator rod 9 rotates, it drives the hydraulic valve rotating core 7 to rotate, and the hydraulic valve body 6 controls the flow rate of the hydraulic mechanism, so that the hydraulically controlled fertilizer pushing mechanism 1 starts to accelerate forward, reducing the effect of fertilization affected by the gap in the fertilizer box 14.

[0023] Specific implementation method 2: Combination Figure 1-Figure 3Describe this embodiment. This embodiment is a fast-forward device of a hydraulic fertilizer pushing mechanism. One end of the actuator rod 9 is fixedly connected to a spring 8, and the other end of the spring 8 is fixedly placed. A spring 8 is fixedly installed at the end of the actuator rod 9, and the other end of the spring 8 is fixed. When the fertilizer pushing mechanism 1 continues to move forward to the middle part, there is no longer a large gap in the fertilizer box 14, and the guide rail 2 and the pulley 3 are no longer in contact. The spring 8 contracts and pulls the actuator rod 9 to restore the actuator rod 9 to its original position. The actuator rod 9 drives the hydraulic valve core 7 to return to its original position, and the hydraulic valve body 6 controls the hydraulic mechanism to restore the initial flow rate, so that the fertilizer pushing mechanism 1 moves forward at a uniform speed according to the initial speed and continues to fertilize.

A connecting piece 11 is installed between the actuator rod 9 and the pull rod 5. The connecting piece 11 is placed horizontally. The pull rod 5 drives the actuator rod 9 to swing through the connecting piece 11. With such an arrangement, if the pull rod 5 is damaged during long-term use, it can be replaced separately in time.

[0026] Specific implementation method five: Combination Figure 1-Figure 3 The present embodiment is described as a fast-forward device of a hydraulic fertilizer pushing mechanism. The guide actuator 4 includes a fixed frame 16 and a rotating rod 17. The rotating rod 17 is rotatably mounted on the fixed frame 16. A pulley 3 is mounted on one end of the rotating rod 17. The other end of the rotating rod 17 is fixedly connected to the pull rod 5. The fixed frame 16 is used to limit the displacement of the rotating rod 17, thereby affecting the amplitude of the pull rod 5 pulling the actuator rod 9.

[0027] Specific implementation method six: Combination Figure 1-Figure 3 The present embodiment is described. The present embodiment is a fast-forward device of a hydraulic fertilizer pushing mechanism. A connecting block 18 is fixedly installed at one end of the rotating rod 17, and a second connecting block 19 is fixedly installed at the other end of the rotating rod 17. A pulley 3 is rotatably installed on the connecting block 18, and the pull rod 5 is fixedly connected to the second connecting block 19. The pulley 3 and the pull rod 5 are fixedly installed on the connecting block 18 and the second connecting block 19 to improve the stability of the guide actuator 4.

[0028] Specific implementation method seven: Combination Figure 1-Figure 3The present embodiment is described. The present embodiment is a fast-forward device of a hydraulic fertilizer pushing mechanism. The fertilizer pushing mechanism includes a hydraulic rod 12 and a fertilizer pushing plate 13. The fertilizer pushing plate 13 is fixedly mounted on the end of the hydraulic rod 12. The guide rail 2 is fixedly mounted on the side wall of the hydraulic rod 12. One end of the hydraulic rod 12 is fixedly connected to the hydraulic mechanism, and the hydraulic mechanism drives the hydraulic rod 12 to advance or retreat. The other end of the hydraulic rod 12 is fixedly mounted with a fertilizer pushing plate 13. The fertilizer pushing plate 13 is arranged in a fertilizer box 14. The fertilizer pushing plate 13 is used to push the fertilizer 15 in the fertilizer box 14 out of the fertilizer box 14 to spread fertilizer on the land.

[0029] The working principle of the present invention is combined with Figure 4 As shown, the push rod opens the valve body through the guide execution structure. After the valve body is opened, the hydraulic system increases the oil supply to the hydraulic cylinder. After the hydraulic cylinder increases the oil supply, it drives the push rod to move forward quickly. The push rod drives the fertilizer pushing plate to move forward quickly. Therefore, the position with a larger gap in the fertilizer pushing box can be quickly pushed forward, so that the material will not be broken during the fertilization process.
