Description

Technical Field

[0001] The utility model relates to agricultural machinery technology, in particular to a furrow pressing device for a peanut ridging and film covering seeder. Background Art

[0002] Peanut is a leguminous plant native to South America. Its seeds are often called peanuts or peanut kernels. Peanut is an important cash crop and food source, widely grown and consumed around the world. Peanut is an annual herb that blooms yellow flowers during its growth period, and then forms underground fruits, which are peanut pods. Its root system is relatively well-developed and can go deep into the soil to find water and nutrients. Peanut is rich in nutrients, mainly including protein, fat, carbohydrates, vitamins and minerals. Among them, peanut has a high protein content and contains a variety of essential amino acids for the human body. It is one of the important sources of plant protein. Peanut can be used as food, oil and feed. Its mature fruits can be eaten directly, or they can be baked, fried, and processed into various foods such as peanut butter, peanut oil, and peanut candy. In addition, peanut oil is a common edible oil, and peanut residue can be used as high-quality feed for animals.

[0003] The world's major peanut production areas include China, India, Nigeria, the United States, Indonesia and other countries. China is one of the world's largest peanut producers, with Shandong, Hebei, Henan, Jiangsu and other places as the main peanut planting areas.

[0004] The peanut ridge-forming and mulching seeder is a mechanical equipment used for peanut planting. It is mainly used to form ridges on the surface, cover the ridges with mulching film and sow seeds. The automated planting system greatly improves the efficiency of planting, reduces labor costs and time costs, reduces the demand for labor and labor costs, and reduces the physical labor requirements for farmers, improving working conditions; reducing the occurrence of human errors, improving the stability and reliability of the planting process, reducing risks, and better adapting to the development trend of large-scale, standardized and intelligent planting.

[0046] The limiting rod 23 penetrates the fixed plate 26 and is rotatably connected to the inner wall of the fixed plate 26 and is slidably connected to the movable plate 22;

[0047] The control assembly 21 is located on one side of the moving plate 22 .

[0048] The specific implementation is that a slide groove is opened on the outer side of the limit rod 23, and the support plate 24 is installed behind the film covering device of the peanut ridging and film covering seeder. The support plate 24 and the movable plate 22 provide support for the control component 21.

[0049] The control component 21 includes:

[0050] A driving member 211, which is fixedly mounted on a side of the fixed plate 26 away from the movable plate 22, and is fixedly connected to the limiting rod 23 via a coupling;

[0051] The stud 214 is slidably sleeved on the outer side of the limiting rod 23, and its two ends abut against the inner wall of the movable plate 22;

[0052] a gear 215 meshing with the stud 214 and rotatably connected to the inner wall of the moving plate 22;

[0053] A connecting column 216, which is fixedly mounted on a side of the gear 215 away from the moving plate 22;

[0054] A second connecting rod 213, one end of which is fixedly mounted on an end of a connecting column 216 away from the gear 215;

[0055] One end of the connecting rod 1 212 is rotatably connected to one side of the fixing plate 26 , and the other end of the connecting rod 1 212 is rotatably connected to the other end of the connecting rod 2 213 .

[0056] The specific implementation is that the driving member 211 includes but is not limited to a motor, which is electrically connected to an external power supply and is controlled by an external PLC programming program. The inner wall of the stud 214 has a protrusion, so that the stud 214 can slide along the slide groove on the limit rod 23; start the driving member 211, the driving member 211 drives the limit rod 23 to rotate, and the limit rod 23 drives the stud 214 to rotate. Since the stud 214 is engaged with the gear 215, the stud 214 drives the gear 215 to rotate, and the connecting rod 213 also rotates with the gear 215. At the same time, the gear 215 drives the stud 214 to slide horizontally along the slide groove of the limit rod 23, and also drives the movable plate 22 to move in the same direction, and the movable plate 22 drives the groove pressing assembly 1 to move in the same direction; when the groove pressing assembly 1 moves to the end position, the connecting rod 1 212 and the connecting rod 2 213 are at the longest length connected to each other.

[0060] The specific implementation method is that the translation drive member 11 includes but is not limited to an electric telescopic rod, which is electrically connected to an external power supply and is controlled by an external PLC programming program. When the extrusion component 12 completes the last section of grooving work, the grooving component 1 needs to return to its original position to facilitate the start of a new grooving work. The translation drive member 11 is started to drive the extrusion component 12 to move upward to prevent repeated grooving of the last distance; when the grooving component 1 returns to the initial position, the translation drive member 11 is started again, and the translation drive member 11 moves vertically downward to drive the extrusion component 12 to return to its initial position.

[0061] Working principle: When in use, when the peanut ridging and film covering seeder reaches the edge of the field, the driving member 211 is started, the driving member 211 drives the limiting rod 23 to rotate, and the limiting rod 23 drives the stud 214 to rotate. Since the stud 214 is meshed with the gear 215, the stud 214 drives the gear 215 to rotate, and the connecting rod 213 also rotates along the gear 215. At the same time, the gear 215 drives the stud 214 to slide horizontally along the slide groove of the limiting rod 23, and also drives the moving plate 22 to move in the same direction, and the moving plate 22 drives the groove pressing assembly 1 to move in the same direction; when the groove pressing assembly 1 moves to the terminal position, the connecting rod 1 212 and the connecting rod 2 213 are at the longest length connected to each other, and the translation driving member 11 is started, and the translation driving member 11 drives the squeezing assembly 12 to move up, and drives the groove pressing assembly 1 back to the initial position under the rotation of the connecting rod 213, and the translation driving member 11 is started again to drive the squeezing assembly 12 to move down, and also returns to the initial position, so as to prepare to start the next peanut planting operation.
