DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0034] Example: An automatic sowing device for pepper planting, please refer to Figure 1-Figure 5, including a cart 1, on which a charging hopper 2 is embedded, the bottom of the charging hopper 2 is tilted with the left side lower and the right side higher, the left side of the cart 1 is rotatably connected with a rotating shaft 4, and wheels 3 are connected to the front and rear ends of the rotating shaft 4, and a motor 5 is installed on the top of the cart 1, and the output shaft of the motor 5 is transmission-connected with the rotating shaft 4 to drive the rotating shaft 4 to drive the wheels 3 to rotate. In the present invention, the output shaft of the motor 5 can be transmission-connected with the rotating shaft 4 through a chain drive component, a belt drive component or a synchronous belt drive component, and a rotating drum 6 is rotatably connected at the discharge port of the charging hopper 2 through a rotating shaft, and the outer wall of the rotating drum 6 is evenly spaced along the circumferential direction with at least two rows of filling grooves for filling seeds, and each row of filling grooves has at least three grooves along the circumferential direction. The rotating drum 6 is evenly distributed axially, and the rotating shaft on the rotating drum 6 passes through the charging hopper 2 and is connected to the rotating shaft 4. The rotation of the rotating shaft 4 drives the rotating drum 6 to rotate for sowing. In the present invention, the rotating shaft on the rotating drum 6 can be connected to the rotating shaft 4 through a chain drive assembly, a belt drive assembly or a synchronous belt drive assembly. A ditching pear head 71 is connected to the bottom of the cart 1. The ditching pear head 71 is located on the right side of the discharge port of the charging hopper 2. Two covering plates 7 are connected to the bottom of the cart 1, one in front and one in the back. The covering plate 7 is located on the left side of the discharge port of the charging hopper 2. The covering plate 7 is installed obliquely, and the distance between the two covering plates 7 gradually lengthens from left to right. The cart 1 is provided with a soil turning mechanism, and the left side of the cart 1 is provided with a compacting mechanism.

[0035] Pour the pepper seeds into the loading hopper 2, and the pepper seeds then enter the containing groove on the rotating drum 6. The control motor 5 can drive the rotating shaft 4 to drive the wheel 3 to rotate. The rotation of the wheel 3 can make the device move by itself, so there is no need to manually push the device to move, which can save labor; the soil can be plowed by the soil turning mechanism, and the plowed soil can be furrowed by the furrowing pear head 71 to sow the pepper seeds to a suitable depth. The rotation of the shaft 4 drives the drum 6 to rotate. When the containing groove on the drum 6 is rotated to face downward, the pepper seeds inside can be poured out so that the pepper seeds fall into the ridge ditch to realize automatic sowing. Since the covering plate 7 is installed obliquely, the distance between the two covering plates 7 gradually lengthens from left to right, so the covering plate 7 moves to the right to push the soil into the ridge ditch to cover the pepper seeds to realize automatic covering. The soil can be compacted by the compacting mechanism, thereby preventing the pepper seedlings from lodging due to the soil being too soft after growing out. In this way, the equipment integrates the functions of tilling, furrowing, sowing, covering and compacting. It has diverse functions and strong practicality, thereby reducing labor intensity and improving sowing efficiency and actual production efficiency.

[0036] See also Figure 4In the present invention, the tilling mechanism includes an H-shaped swing plate 80 hinged on the top of the cart 1 and capable of swinging up and down. An electric push rod 81 is hinged on the top of the cart 1. The telescopic rod of the electric push rod 81 is hinged to the H-shaped swing plate 80 to drive the H-shaped swing plate 80 to swing up and down. A tilling wheel 84 for tilling the soil is rotatably connected on the right side of the H-shaped swing plate 80. The tilling wheel 84 is located on the right side of the charging hopper 2. Two gears B83 are rotatably connected to the top of the cart 1 front and back. The gear B83 is transmission-connected to the rotating shaft 4. The gear B83 can be transmission-connected to the rotating shaft 4 through a chain transmission component, a belt transmission component or a synchronous belt transmission component. Two gears A82 are rotatably connected to the H-shaped swing plate 80 front and back. The two gears A82 swing downward and can mesh with the two gears B83 respectively. The gear A82 is transmission-connected to the tilling wheel 84. The gear A82 can be transmission-connected to the tilling wheel 84 through a chain transmission component, a belt transmission component or a synchronous belt transmission component.

[0037] The telescopic rod of the electric push rod 81 is controlled to shorten to pull the H-shaped swing plate 80 to drive the gear A82 and the tilling wheel 84 to swing downward, the gear A82 swings downward and engages with the gear B83, the tilling wheel 84 swings downward and inserts into the soil, the rotation of the rotating shaft 4 drives the gear B83 to rotate, the rotation of the gear B83 drives the gear A82 to rotate, the rotation of the gear A82 drives the tilling wheel 84 to rotate for tilling, and the telescopic rod of the electric push rod 81 is controlled to extend to push the H-shaped swing plate 80 to drive the gear A82 and the tilling wheel 84 to swing upward and reset.

[0038] See also Figure 5 In the present invention, the compacting mechanism includes two lifting blocks 101 symmetrically slidably connected to the left side of the cart 1 through a slide groove, and a soil pressing wheel 102 is rotatably connected between the two lifting blocks 101. The diameter of the soil pressing wheel 102 gradually increases from the middle to the front and rear sides. The outer wall of the soil pressing wheel 102 is spaced apart with grooves along the circumferential direction, and a tension spring 103 is connected between the lifting block 101 and the cart 1.

[0039] The tension spring 103 can ensure that the soil pressing wheel 102 is always pressed tightly against the soil. When the device moves, the soil pressing wheel 102 rotates accordingly. In this way, the soil pressing wheel 102 can compact the soil to prevent the pepper seedlings from falling over after growing out due to the soil being too soft. The grooves on the soil pressing wheel 102 can increase the contact area between the soil pressing wheel 102 and the soil, thereby increasing the force of compacting the soil. In addition, the grooves can also help expel air from the soil, further improving the density of the soil.

[0040] See also Figure 5-Figure 6A cleaning mechanism for cleaning the soil-pressing wheel 102 is provided on the left side of the trolley 1, and the cleaning mechanism includes a brush 104 slidably connected to the left side of the trolley 1 through a slide groove, and the brush 104 can move forward and backward. The brush 104 is located on the upper side of the soil-pressing wheel 102, and two compression springs A105 are symmetrically connected between the brush 104 and the trolley 1. A wire tube 106 is embedded on the left front side of the trolley 1, and a 7-shaped pull plate 108 that can move left and right is slidably connected to the left front side of the trolley 1 through a slide groove. A pull rope 107 is connected to the top of the 7-shaped pull plate 108, and the pull rope 107 passes through the wire tube 106 and is connected to the front side of the brush 104. A cam A109 is connected to the front side of the rotating shaft 4, and the cam A109 contacts the 7-shaped pull plate 108.

[0041] When the soil pressing wheel 102 rotates, it always keeps in close contact with the brush 104, so that the soil adhering to the soil pressing wheel 102 can be cleaned by the brush 104 to prevent the soil from staying on the soil pressing wheel 102 and affecting the soil compaction effect. The rotation of the rotating shaft 4 drives the cam A109 to rotate. When the longer end of the cam A109 rotates to contact with the 7-shaped pull plate 108, the cam A109 continues to rotate to push the 7-shaped pull plate 108 to move right. The 7-shaped pull plate 108 moves to the right and pulls the brush 104 forward through the pull rope 107. The compression spring A105 is compressed accordingly. When the longer end of the cam A109 rotates to disengage from the 7-shaped pull plate 108, the compression spring A105 resets the brush 104 and moves backward. The brush 104 moves backward and pulls the 7-shaped pull plate 108 to the left through the pull rope 107. This cycle repeats itself, allowing the brush 104 to move back and forth, thereby improving the cleaning efficiency and effect.

[0042] See also Figure 7 A sprinkler mechanism is provided on the left outer wall of the loading hopper 2, and the sprinkler mechanism includes a water tank 91 connected to the left outer wall of the loading hopper 2. Two connecting plates 92 that can swing back and forth are symmetrically hinged on the left outer wall of the loading hopper 2. The connecting plate 92 is located below the water tank 91. A sprinkler head 93 is installed on the left side of the connecting plate 92. The sprinkler head 93 is located at the upper left of the soil pressing wheel 102, and the sprinkler head 93 is connected to the water tank 91 through an infusion pipe 94.

[0043] Clean water is poured into the water tank 91, and then flows into the nozzle 93 through the infusion pipe 94. The nozzle 93 then sprays the clean water out and sprinkles it on the soil. In this way, watering can be automatically performed after sowing, thereby promoting the germination and growth of pepper seeds.

[0044] See also Figure 7The trolley 1 is provided with a toggle mechanism for toggling the connecting plate 92 to swing back and forth, the toggle mechanism includes a connecting rod 95 connected between the two connecting plates 92, a guide groove 98 is opened on the rear connecting plate 92, a rotating wheel 96 is connected to the rear side of the rotating shaft 4, and a spiral groove 97 is opened on the outer wall of the rotating wheel 96. A toggle rod 99 that can move back and forth is slidably connected to the left rear side of the top of the trolley 1 through a guide rail, the upper part of the toggle rod 99 penetrates into the guide groove 98 on the rear connecting plate 92, and the lower part of the toggle rod 99 extends into the spiral groove 97 on the rotating wheel 96.

[0045] The rotation of the rotating shaft 4 drives the rotating wheel 96 to rotate. When the rotating wheel 96 rotates, the lever 99 can move forward and backward under the guidance of the spiral groove 97. The lever 99 moves forward and backward to drive the rear connecting plate 92 to swing forward and backward. The swinging of the rear connecting plate 92 forward and backward drives the front connecting plate 92 to swing forward and backward through the connecting rod 95, so that the two nozzles 93 can swing forward and backward synchronously. The swinging of the nozzle 93 forward and backward can increase the spraying area, so that the clean water can be evenly sprayed on the soil to improve the spraying effect.

[0046] See also Figure 8-Figure 9 The charging hopper 2 is provided with a cleaning mechanism for screening and cleaning seeds. The cleaning mechanism includes two mounting frames 111 respectively connected to the inner walls of the left and right sides of the charging hopper 2. A screen 112 that can move left and right is slidably connected between the two mounting frames 111. The screen 112 is designed to be high in the middle and low outside. A push plate 113 that can move left and right is slidably connected to the left side of the charging hopper 2. The push plate 113 penetrates the left mounting frame 111 and is connected to the screen 112. The push plate 113 is connected to the charging hopper 2. Two compression springs B114 are symmetrically connected between the front and rear outer walls of the hopper 2. A cam B115 is connected to the front end of the rotating shaft on the rotating drum 6. The cam B115 is in contact with the push plate 113. A discharge frame 116 is installed on the right side of the loading hopper 2. A frame cover 117 that can rotate up and down is hinged on the upper part of the discharge frame 116. A pull rod 118 that can move left and right is slidably connected to the right side of the loading hopper 2. The left end of the pull rod 118 is connected to a push plate 119 for pushing impurities on the screen 112 to the right.

[0047] The pepper seeds can fall from the mesh holes on the screen 112 to the bottom of the charging hopper 2, while the impurities such as leaves, branches, and stones mixed in the pepper seeds are blocked by the screen 112. In this way, the pepper seeds can be screened and impurities can be removed to prevent the impurities such as leaves, branches, and stones from mixing with the pepper seeds into the soil and affecting the growth and development of the pepper seeds. Since the screen 112 is designed with a high middle and low outside tilt, the impurities such as leaves, branches, and stones will slide to the middle of the screen 112 to prevent the impurities such as leaves, branches, and stones from clogging the screen 112. The rotation of the rotating shaft on the drum 6 drives the cam B115 to rotate. When the longer end of the cam B115 rotates to contact the push plate 113, the cam B115 continues to rotate to push the push plate 113 to move to the right, and the compression spring B114 is compressed accordingly, so that the screen 112 can move to the right. When the longer end of the cam B115 rotates to disengage from the push plate 113, under the resetting action of the compression spring B114, the push plate 113 drives the screen 112 to move to the left, and the cycle repeats, so that the screen 112 can repeatedly shake left and right, thereby avoiding blockage of the screen 112 and improving the screening efficiency and effect. Pulling the pull rod 118 to the right can move the push plate 119 to the right to push impurities such as leaves, branches, and stones on the screen 112 to the right, and the cleaning operation is simple and quick.

[0048] See also Fig.10 A curved shielding cover 12 is connected to the right side of the top of the H-shaped swing plate 80, and the curved shielding cover 12 covers the tilling wheel 84. The curved shielding cover 12 can block the soil to prevent the soil from splashing around and accidentally injuring the sowing personnel.

[0049] See also Fig.11 A valve 13 is installed on the infusion tube 94, and the valve 13 can intercept the water in the infusion tube 94 and adjust the flow rate of the water, thereby avoiding the waste of water resources.
