Detailed ways

Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

As shown in Figures 1 to 7, the integrated seed and fertilizer seeder includes a machine body, on which a sowing mechanism 1, a seed delivery mechanism 2 and a soil covering mechanism 3 are sequentially installed along the front and rear directions of the machine body. A plurality of sowing mechanisms 1 can be arranged side by side according to the number of rows of garlic to be planted as needed. The seed delivery mechanism 2 delivers the garlic cloves into the sowing mechanism 1, the sowing mechanism 1 sows the garlic cloves into the soil, and finally the soil covering mechanism 3 covers the soil on the garlic cloves.

The sowing mechanism 1 includes a water trough 11, and a water tank 16 for supplying water and fertilizer into the water trough 11 is arranged on one side of the water trough 11. The water tank 16 is filled with water dissolved with a certain amount of fertilizer. The water trough 11 is connected to the water tank 16. A liquid level sensor is installed in the water trough 11. When the liquid level in the water trough 11 drops, the water pump in the water tank 16 starts to supply water and fertilizer into the water trough 11, so that the water and fertilizer liquid level in the water trough 11 always maintains a predetermined height.

A liftable metering tube 12 is provided in the water tank 11, and the metering tube 12 is connected from top to bottom. A compression spring 156 is installed between the metering tube 12 and the water tank 11. In the initial state, there is a gap between the bottom end of the metering tube 12 and the bottom of the water tank 11, so that the water and fertilizer in the water tank 11 enter the metering tube 12. A water outlet hole compatible with the metering tube 12 and a gate 13 for closing the water outlet hole are provided on the bottom surface of the water tank 11. A driving member for controlling the opening and closing of the gate 13 is installed on the water tank 11. A circle of filter screen 111 is provided around the edge of the water outlet hole at the top of the water outlet hole. The metering tube 12 and the filter screen 111 always have a contact portion to prevent large particles of impurities in the metering tube 12 from entering the water tank 11.

Two rows of clamping rods 14 and a motion device 15 are installed in the water tank 11. The bottom of the clamping rod 14 is provided with a rough surface. The motion device 15 is used to control the clamping, loosening and lifting of the clamping rod 14, and is also used to control the lifting of the quantitative tube 12. The bottom ends of the two rows of clamping rods 14 are located in the quantitative tube 12. A feed port is provided on the side wall of the water tank 11. The seed delivery mechanism 2 puts the garlic cloves into the quantitative tube 12 through the feed port and is located between the two rows of clamping rods 14. The garlic cloves float on the water fertilizer, so that the seed buds of the garlic cloves face upward.

The motion device 15 includes a first connecting frame 151 and a second connecting frame 152, wherein one row of clamping rods 14 is connected to the first connecting frame 151 through an elastic telescopic rod 141, and another row of clamping rods 14 is fixedly installed on the second connecting frame 152. A lifting frame 153 and a driving source 1531 for driving the lifting frame 153 to move up and down are installed in the water tank 11. The driving source 1531 is an electric push rod or a hydraulic rod. The first connecting frame 151 and the second connecting frame 152 are both connected to the lifting frame The first connecting frame 151 is slidably connected to the lifting frame 153 and can only slide horizontally relative to the lifting frame 153. A tension spring 1532 is connected between the second connecting frame 152 and the lifting frame 153. A left slide groove 154 and a right slide groove 155 are provided on the front and rear inner walls of the water tank 11. The two ends of the first connecting frame 151 are adapted to the two left slide grooves 154, and the two ends of the second connecting frame 152 are adapted to the two right slide grooves 155. The left slide groove 154 is composed of an inclined slide groove and a vertical slide groove, and the right slide groove 155 is a ring slide groove. The top and bottom of the annular chute are inclined toward the middle of the right end thereof. The top and bottom of the annular chute are provided with a check block 1551 for allowing the second connecting frame 152 to pass only in one direction. The check block 1551 is hinged in the right chute 155. A spring is installed between the check block 1551 and the inner wall of the water tank 11. When the lifting frame 153 descends, the first connecting frame 151 slides downward in the inclined chute, and the two rows of clamping rods 14 approach each other to clamp the garlic cloves. When the second connecting frame 152 is moved downward, the two rows of clamping rods 14 move upward, and ... After the connecting frame 152 moves to the bottom of the annular slide groove and passes the check block 1551, the garlic cloves are pressed into the soil, and the tension spring 1532 releases its elastic potential energy to make the second connecting frame 152 slide to the right, thereby entering the right side of the right slide groove 155, so that the distance between the two rows of clamping rods 14 becomes larger and the garlic cloves are released. Finally, the lifting frame 153 rises and resets, and the second connecting frame 152 moves along the right slide groove 155 to pull the tension spring 1532 open, and finally returns to its original position after passing through the check block 1551.

The quantitative tube 12 and the lifting frame 153 are respectively hinged with a first connecting rod 157 and a second connecting rod 158, the first connecting rod 157 is hinged with the second connecting rod 158, a guide groove 159 is provided in the water tank 11, and a slider 1571 adapted to the guide groove 159 is provided on the first connecting rod 157, and the guide groove 159 is composed of a vertical groove and an arc groove. When the lifting frame 153 descends, the slider 1571 slides in the vertical groove, thereby causing the quantitative tube 12 to descend. When the slider 1571 reaches the arc groove, the two rows of The clamping rod 14 clamps the garlic clove, the metering tube 12 is inserted into the water outlet on the water tank 11, and the gate 13 is opened. The water and fertilizer in the metering tube 12 flow out to moisten the soil below. Since the center of the arc groove is located on the hinge axis of the first connecting rod 157 and the metering tube 12 at this time, when the lifting frame 153 continues to descend, the first connecting rod 157 rotates with the center of the arc groove, and the metering tube 12 no longer descends. The clamping rod 14 clamps the garlic clove and enters the moist soil. Since the soil is moist, the garlic clove seed buds can be better kept upward.

Working principle: the seed delivery mechanism 2 puts the garlic clove into the quantitative tube 12 through the feed port and is located between the two rows of clamping rods 14. The garlic clove floats on the water and fertilizer, so that the seed buds of the garlic clove are upward, the lifting frame 153 descends, and the first connecting frame 151 slides downward in the inclined slide groove. The two rows of clamping rods 14 approach each other to clamp the garlic clove, and the quantitative tube 12 descends at the same time. When the slider 1571 reaches the arc groove, the two rows of clamping rods 14 approach each other to clamp the garlic clove, the gate 13 opens, and the water and fertilizer of the quantitative tube 12 flow out to moisten the soil below, and the lifting frame 153 continues to descend. When the first connecting rod 157 is about to descend, the first connecting rod 157 rotates with the center of the arc groove, the quantitative tube 12 no longer descends, and the two rows of clamping rods 14 clamp the garlic cloves and insert them into the moist soil. Because the soil is moist, the garlic cloves can be better kept upward. Finally, the covering mechanism 3 brings the two sides of the garlic cloves closer to the garlic cloves and smoothes the soil surface. When resetting, the lifting frame 153 rises. When the slider 1571 is about to form an arc groove, the gate 13 is closed, and the quantitative tube 12 continues to rise so that a gap appears between its bottom and the bottom wall of the water tank 11, and water and fertilizer enter the quantitative tube 12 from the gap to wait for the next sowing.

Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
