Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural machinery technology, specifically a four-bar linkage contouring device for drip irrigation. Background Technology
[0002] A seeder drip irrigation laying device is an agricultural machine that integrates the functions of sowing and drip irrigation tape laying. It can complete the laying of drip irrigation tape at the same time as sowing, and is suitable for the promotion of water-saving irrigation technology. This equipment is usually equipped with a special ditching, sowing, soil covering and drip irrigation tape laying mechanism, which can improve the efficiency of operation and reduce labor costs. In traditional seeder drip irrigation laying devices, the ditching and soil covering mechanism is often fixedly connected to the main body of the machine. Therefore, during use, the ditching depth is inconsistent and the amount of soil covering the drip irrigation pipe is inconsistent, which greatly affects the normal growth of crops in the later stage. Utility Model Content
[0003] To overcome the above-mentioned defects, this utility model provides a four-bar linkage contouring device for drip irrigation, which solves the problem that traditional drip irrigation laying equipment for seeders has inconsistent furrow depth and inconsistent soil coverage on drip irrigation pipes.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a four-bar linkage contouring device for drip irrigation, including a drip irrigation pipe trenching and soil covering mechanism. A connecting frame is provided on the top of the drip irrigation pipe trenching and soil covering mechanism. A sleeve three and a sleeve four are fixedly connected to the connecting frame. An upper connecting rod is provided at both ends of the sleeve three, and a lower connecting rod is provided at both ends of the sleeve four. A drip irrigation pipe fixing frame is provided on the lower connecting rod and the upper connecting rod. A limit rod one and a bolt two are provided at one end of the upper connecting rod, and a bolt one and a guide rod one are provided at both ends of the upper connecting rod.
[0005] One end of the lower connecting rod is provided with a limiting rod 2 and a bolt 4. Both ends of the lower connecting rod are provided with a guide rod 2 and a bolt 3. The drip irrigation pipe fixing frame is fixedly connected with a sleeve 2 and a sleeve 1. The limiting rod 1 and the limiting rod 2 are provided with a contoured tension spring.
[0006] As a further embodiment of this utility model: the drip irrigation pipe trenching and soil covering mechanism is installed on the bottom of the connecting frame, both ends of the second guide rod and the second limiting rod are inserted into the lower connecting rod, the third bolt is threadedly connected to both ends of the second guide rod, and the two ends of the second guide rod are respectively inserted into the fourth sleeve and the second sleeve.
[0007] As a further embodiment of this utility model: both ends of the first guide rod and the first limiting rod are inserted into the upper connecting rod, the first bolt is threadedly connected to both ends of the first guide rod, and the two first guide rods are respectively inserted into the third sleeve and the first sleeve.
[0008] As a further embodiment of this utility model: the second limiting rod is disposed on the end of the lower connecting rod near the drip irrigation pipe fixing frame, the bolt is threadedly connected to both ends of the second limiting rod, and the first limiting rod is disposed on the end of the upper connecting rod near the connecting frame.
[0009] As a further embodiment of this utility model: the two bolts are threadedly connected to the two ends of the first limiting rod, the contour spring is inclined, and the two ends of the contour spring are respectively installed on the first limiting rod and the second limiting rod.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a drip irrigation pipe trenching and soil covering mechanism, a lower connecting rod, an upper connecting rod, a limiting rod one, a limiting rod two, a guide rod two, a bolt three, and a bolt four, when the drip irrigation pipe trenching and soil covering mechanism moves in an uneven ground environment, the lower connecting rod and the upper connecting rod tilt due to the cooperation of bolt one, guide rod one, bolt three, and guide rod two. At the same time, with the assistance of limiting rod one, limiting rod two, and the elastic force of the contour spring, the drip irrigation pipe trenching and soil covering mechanism floats up and down. The cooperation of limiting rod one and limiting rod two limits the vertical floating distance of the drip irrigation pipe trenching and soil covering mechanism, which facilitates the normal use of the drip irrigation pipe trenching and soil covering mechanism. Therefore, the vertical floating of the drip irrigation pipe trenching and soil covering mechanism makes the depth of the opened drip irrigation pipe trenches consistent, and the soil covering on the drip irrigation pipes more uniform, which is conducive to the increase of crop yield and income, and greatly improves the practicality of the drip irrigation four-link contour device.

[0014] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0015] like Figure 1-2As shown, this utility model provides a technical solution: a four-bar linkage contouring device for drip irrigation, including a drip irrigation pipe trenching and soil covering mechanism 1. The drip irrigation pipe trenching and soil covering mechanism 1 is installed on the bottom of the connecting frame 6. The two ends of the guide rod 2 12 and the limiting rod 2 8 are both inserted into the lower connecting rod 2. The bolt 3 13 is threadedly connected to the two ends of the guide rod 2 12, and the two ends of the guide rod 2 12 are respectively inserted into the sleeve 4 18 and the sleeve 2 16. The connecting frame 6 is used to support and fix the drip irrigation pipe trenching and soil covering mechanism 1, and through the cooperation of the sleeve 3 17 and the sleeve 4 18, the lower connecting rod 2 and the upper connecting rod 4 are tilted.
[0016] The top of the drip irrigation pipe trenching and covering mechanism 1 is equipped with a connecting frame 6. Sleeve 3 17 and sleeve 4 18 are fixedly connected to the connecting frame 6. Both ends of sleeve 3 17 are equipped with upper connecting rods 4, and both ends of sleeve 4 18 are equipped with lower connecting rods 2. Drip irrigation pipe fixing frames 5 are installed on the lower connecting rods 2 and upper connecting rods 4. One end of the upper connecting rod 4 is equipped with a limiting rod 1 7 and a bolt 2 10. Bolt 2 10 is threaded to both ends of the limiting rod 1 7. The contour spring 3 is inclined, and both ends of the contour spring 3 are respectively installed on the limiting rod 1 7 and the limiting rod 2 8. The contour spring 3, through the cooperation of the limiting rod 1 7 and the limiting rod 2 8, drives the lower connecting rod 2 and the upper connecting rod 4 to reset, so as to allow the drip irrigation pipe trenching and covering mechanism 1 to float up and down.
[0017] Both ends of the upper connecting rod 4 are provided with bolts 9 and guide rods 11. Both ends of the guide rods 11 and the limiting rods 7 are inserted into the upper connecting rod 4. Bolts 9 are threaded onto both ends of the guide rods 11, and the two guide rods 11 are respectively inserted into sleeves 17 and 15. Through the cooperation of bolts 9, the two ends of the upper connecting rod 4 are respectively installed on sleeves 17 and 15.
[0018] One end of the lower connecting rod 2 is equipped with a limiting rod 2 8 and a bolt 4 14. The limiting rod 2 8 is located on the end of the lower connecting rod 2 near the drip irrigation pipe fixing frame 5. The bolt 4 14 is threaded to both ends of the limiting rod 2 8. The limiting rod 1 7 is located on the end of the upper connecting rod 4 near the connecting frame 6. Both ends of the lower connecting rod 2 are equipped with a guide rod 2 12 and a bolt 3 13. The drip irrigation pipe fixing frame 5 is fixedly connected with a sleeve 2 16 and a sleeve 1 15. The limiting rod 1 7 and the limiting rod 2 8 are equipped with a contour spring 3. The cooperation of the limiting rod 1 7 and the limiting rod 2 8 serves to limit the vertical floating distance of the drip irrigation pipe trenching and covering mechanism 1, so as to facilitate the normal use of the drip irrigation pipe trenching and covering mechanism 1.
[0019] The working principle of this utility model is as follows: When the drip irrigation pipe trenching and covering mechanism 1 moves in an uneven environment, the cooperation of bolt 9, guide rod 11, guide rod 12 and bolt 13 causes the lower connecting rod 2 and the upper connecting rod 4 to tilt. Then, with the assistance of the elastic force of the limiting rod 7, limiting rod 8 and the conformal tension spring 3, the drip irrigation pipe trenching and covering mechanism 1 floats up and down. At the same time, the cooperation of the limiting rod 7 and limiting rod 8 is used to limit the vertical floating distance of the drip irrigation pipe trenching and covering mechanism 1, so that the depth of the drip irrigation pipe trench opened by the drip irrigation pipe trenching and covering mechanism 1 is consistent.
