Description

Technical Field

[0001] The invention specifically relates to the technical field of fertilizer spreading, and in particular to a spreading device for selenium-rich fertilizer. Background Art

[0002] Selenium-rich biofertilizer is a fertilizer that contains selenium and uses the life activities of microorganisms to improve the nutritional status of plants. It is mainly composed of microbial agents and selenium sources. During the growth and reproduction of microorganisms in the soil, they can convert selenium into a form that is easily absorbed by plants. Selenium in the soil may exist in a variety of forms, some of which are difficult for plants to absorb. The microorganisms in selenium-rich biofertilizers can convert insoluble selenium compounds into forms such as selenate or selenite that can be absorbed by plants through their own metabolic activities. The microorganisms in selenium-rich biofertilizers can decompose organic matter in the soil, release nutrients, and improve the structure and aeration of the soil.

[0003] Compared with traditional fertilizers, selenium-rich biofertilizers need to be effectively mixed with soil when applied. When the microorganisms in the selenium-rich biofertilizer are active in the soil, they will decompose the organic matter in the soil. The addition of selenium-rich biofertilizers brings new microbial populations to the soil, and these microorganisms interact with the original microorganisms in the soil.

[0004] At present, when the conventional fertilizer application device is spreading fertilizer, due to the different ridge spacings between crops, the spacing of the fertilizer feeding device cannot be effectively adjusted during the fertilization, which may cause irreversible damage to the crops during the fertilization. In addition, when the conventional fertilizer application device is operating, due to the different structures of the equipment, the fertilizer application device can only apply fertilizer to crops with multiple ridge spacings or single ridge spacings. Due to the different production processes of the equipment, the switching between multiple ridge spacings and single ridge spacings during fertilization cannot be effectively realized, which results in low utilization of the fertilizer application device.

[0005] After searching, Chinese Patent Publication No. CN202022194610.3 discloses a fertilizer uniform application device; it includes an arc-shaped baffle, a material-throwing plate, a partition plate and a fertilizer barrel, wherein a bottom plate is installed at the rear portion of the bottom end of the arc-shaped baffle, a material-throwing plate is arranged on the upper portion of the bottom plate, a stepping motor is installed at the lower portion of the bottom plate, the material-throwing plate is installed on the upper rotating shaft end of the stepping motor, a partition plate is installed on the material-throwing plate, two fixed beams are installed at the rear portion of the upper end of the arc-shaped baffle, a fixed plate is installed between the two fixed beams, a fertilizer barrel is installed in the middle of the fixed plate, the fertilizer barrel includes a barrel body, a material-pickup tube, a material-pickup motor, a material-pickup blade and a discharging pipe, a material-pickup tube is installed at the bottom end of the barrel body, a material-pickup blade is arranged inside the material-pickup tube, a material-pickup motor is installed on the outer wall of the material-pickup tube, the rotating shaft end of the material-pickup motor is fixedly connected to the material-pickup blade, and a discharging pipe is installed at the bottom end of the material-pickup tube;

[0006] When the device in the above patent is spreading fertilizer, the stepper motor drives the throwing plate and the partition plate to rotate, so that the fertilizer can be effectively thrown out and spread. Although this can achieve the effect of fertilization, during the process of feeding the fertilizer inside the cylinder, the equipment is interfered by external forces and may be tilted. This will cause the materials between two adjacent partition plates to be different, and the uniformity of fertilization cannot be effectively guaranteed. In addition, in the above patent, fertilization is carried out by rotation, and the range of fertilizer spreading is large. This will cause fertilizer waste when fertilizing in the field. In addition, the fertilizer in the above patent can only be spread on the surface of the land. During the decomposition of the fertilizer, the nutrients cannot be effectively absorbed by the soil, resulting in nutrient loss. Summary of the invention

At the same time, the installation position of the arc frame on the fixed frame can be adjusted to achieve the fertilization effect on crops with different ridge spacings; when fertilizing crops with single ridge spacings, the driving motor is connected to the first sprocket through the eighth sprocket.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention, when in use, when selenium-rich fertilizer is added to the material box, when it is necessary to fertilize crops with multiple ridge spacings, the partition is placed on one side of the discharge port, the fixed frame is connected to the traction device, and the eighth sprocket and the fourth sprocket are driven by the driving motor to cooperate, so that the roller in the first discharge driving structure is in contact with the soil. When the roller rolls, the third sprocket on one side of the roller is connected to the first sprocket through a chain, and the first sprocket and the second sprocket are connected through a chain. In this way, the two square rods of the installed first sprocket and the second sprocket simultaneously drive the dial wheels inside the multiple discharge hoppers to rotate, so that the fertilizer in the material box is transported to the discharge port at the bottom of the discharge hopper. During the transportation process, the connecting rod can also be driven to rotate by the adjusting rod to adjust the spacing between the adjusting plate of the connecting rod mountain and the discharge port, thereby effectively adjusting the flow rate of the fertilizer;

[0023] 2. The present invention, when fertilizing with multiple ridge spacing, through the connection between the third sprocket and the first sprocket, and the connection between the first sprocket and the second sprocket, when the roller rolls on the land, the first sprocket and the second sprocket drive the square rod penetrating the lower hopper to drive the paddle wheel to transfer the selenium-rich fertilizer in the material box to the discharge port at the bottom of the lower hopper. When transmitting, an adjustment plate is also provided between the paddle wheel and the discharge port at the bottom of the lower hopper. The adjustment plate is installed with a connecting rod, and the outside of the connecting rod is fixedly installed with the adjustment rod. In this way, when fertilizing, the connecting rod is driven to rotate by the adjustment rod, thereby effectively realizing the spacing between the adjustment plate and the discharge port, thereby effectively adjusting the fertilizer flow rate up and down;

[0024] 3. In the present invention, the fertilizer is transmitted from the discharge port at the bottom of the lower hopper to the lower feeding pipe through the conveying pipe. The lower feeding pipe is installed on the rear side of the arc frame, and a plow is arranged on the front side of the arc frame. The bottom of the plow should be lower than the bottom of the arc frame. In this way, when the traction device drives the fixed frame to move forward, the plow opens the soil by the furrow, and the fertilizer in the lower feeding pipe is applied to the furrow, thereby effectively reducing the nutrient loss caused by the volatilization of the selenium-rich fertilizer, thereby effectively ensuring the improvement of the soil by the selenium-rich fertilizer; when single ridge is being carried out When fertilizing crops with spacing, the eighth sprocket drives the fourth sprocket to rotate through the driving motor. At this time, the roller tilts upward under the action of the support plate to separate the roller from the soil. In this way, when the traction device drives the fixed frame to work forward, the third sprocket on one side of the roller cannot effectively realize the rotation between the first sprocket and the second sprocket, thereby effectively preventing the selenium-rich fertilizer from entering the lower hopper. When fertilizing crops with single ridge spacing, the partition is taken out to transmit the selenium-rich fertilizer in the material box to the lower material port through the dragon roller.

[0025] 4. The present invention, when fertilizing at a single ridge spacing, the driving motor drives the eighth sprocket to rotate, and at the same time the screw rod cooperates with the fixed rod to realize that the fixed rod moves along the double round head slide toward one end of the fixed frame away from the first fertilizing assembly installed through the roller. When the fixed rod moves, the pull rod and the carrier are flipped 90 degrees, so that the soil turning assembly, the second fertilizing assembly and the soil covering assembly are moved to the working position, so as to achieve the fertilization effect on the crops at a single ridge spacing; when fertilizing, the fixed frame realizes the soil turning operation of the soil turning wheel through the carrier, and when the soil turning wheel rolls, one of the fifth sprockets installed between the soil turning wheel and the hanger is connected to the rotating shaft through the chain. The sixth sprocket installed on the rod is connected to realize that the sixth sprocket drives the rotating rod to rotate. At the same time, the two shifting blocks installed on the rotating rod rotate at 90 degrees. When the two shifting blocks rotate, the shifting blocks contact and extrude with the two L-shaped moving frames on one side alternately, so that the two L-shaped moving frames drive the two tooth plates to slide along the C-shaped blocks. In the process of alternating sliding of the two tooth plates, the tooth plates realize the meshing of gears, so as to effectively realize the support shaft through the gears to drive the top swing cylinder to swing left and right. The feed port at the top of the swing cylinder is connected to the bottom of the discharge port through a conveying pipe, so that the swing cylinder can evenly spread the selenium-rich fertilizer in the groove opened by the soil-turning wheel during the swinging process.

[0026] 5. In the present invention, a soil covering assembly is arranged at the rear side of the second fertilizing assembly, and the selenium-rich fertilizer spread by the swing drum is covered with soil through the soil covering assembly. When covering the soil, another fifth sprocket on one side of the soil-turning wheel is linked to the seventh sprocket, and the second bevel gear coaxially arranged on the seventh sprocket is meshed with the first bevel gear installed on the rotating shaft, so that the rotating shaft drives the soil covering plate to rotate effectively, thereby covering the selenium-rich fertilizer with soil.

[0061] See also Figure 1-17 In this embodiment, the soil turning assembly 7 includes a hanger 71; the hanger 71 is fixedly mounted at the bottom of the carrier 63; the hanger 71 is movably mounted with the soil turning wheel 70 through a rotating shaft; two fifth sprockets 72 are fixedly mounted between the soil turning wheel 70 and the hanger 71; one of the fifth sprockets 72 is connected to the sixth sprocket 88 through a chain (not shown);

[0062] By adopting the above technical solution, when fertilizing at a single ridge spacing, the driving motor 100 drives the eighth sprocket 101 to rotate, and at the same time, the screw rod 102 cooperates with the fixed rod 61, so that the fixed rod 61 moves along the double round head slide 60 through the roller to the end away from the fixed frame 3 where the first fertilizing assembly 4 is installed. When the fixed rod 61 moves, the pull rod 62 and the carrier 63 are flipped 90 degrees, so that the soil turning assembly 7, the second fertilizing assembly 8 and the soil covering assembly 9 are moved to the working position, so as to achieve the fertilization effect on the crops at a single ridge spacing;

[0063] See also Figure 1-17 ; In this embodiment, the end of the bottom of the carrier plate 63 away from the soil turning assembly 7 is equipped with a soil covering assembly 9; the soil covering assembly 9 includes a rotating shaft 90; the rotating shaft 90 is movably installed with the carrier plate 63 through a bearing; a limit plate 93 and a first bevel gear 94 are fixedly installed on the rotating shaft 90; wherein; a spring 91 and a soil covering plate 92 are arranged between the limit plate 93 and the bottom of the rotating shaft 90; the spring 91 is located between the soil covering plate 92 and the limit plate 93;

[0064] By adopting the above technical solution, when fertilizing, the fixed frame 3 realizes the tilling operation of the tilling wheel 70 through the carrier 63. When the tilling wheel 70 rolls, one of the fifth sprockets 72 installed between the tilling wheel 70 and the hanger 71 is connected to the sixth sprocket 88 installed on the rotating rod 86 through a chain, so that the sixth sprocket 88 drives the rotating rod 86 to rotate. At the same time, two 90° shifting blocks 87 installed on the rotating rod 86 rotate. When the two shifting blocks 87 rotate, the shifting blocks 87 and the two L-shaped shifting blocks on one side are connected. The moving frames 85 are alternately contacted and extruded, so that the two L-shaped moving frames 85 drive the two tooth plates 84 to slide along the C-shaped block 89. During the alternating sliding of the two tooth plates 84, the tooth plates 84 mesh with the gears 83, thereby effectively supporting the rotating shaft 81 through the gears 83 to drive the top swing cylinder 80 to swing left and right. The feed port at the top of the swing cylinder 80 is connected to the bottom of the discharge port 15 through a conveying pipe, so that the swing cylinder 80 can evenly spread the selenium-rich fertilizer in the grooves opened by the tilling wheel 70 during the swinging process.

[0065] See also Figure 1-13 ; In this embodiment; a second bevel gear 96 is provided on one side of the first bevel gear 94; the first bevel gear 94 and the second bevel gear 96 are arranged vertically; the second bevel gear 96 is coaxially provided with a seventh sprocket 97; the seventh sprocket 97 is connected to another fifth sprocket 72 through a chain (not shown); the seventh sprocket 97 and the mounting shaft of the second bevel gear 96 are movably mounted with the round head plate 95; the round head plate 95 is fixedly mounted at the bottom of the carrier 63;

[0066] By adopting the above technical scheme, a soil covering component 9 is arranged on the rear side of the second fertilizing component 8, and the soil covering component 9 is used to cover the selenium-rich fertilizer spread by the swing drum 80. When covering the soil, the other fifth sprocket 72 on one side of the soil-turning wheel 70 is connected to the seventh sprocket 97, and the second bevel gear 96 coaxially arranged on the seventh sprocket 97 is meshed with the first bevel gear 94 installed on the rotating shaft 90, so that the rotating shaft 90 drives the soil covering plate 92 to rotate effectively, thereby covering the selenium-rich fertilizer with soil.

[0067] The working principle of the present invention is as follows: when the selenium-rich fertilizer is added to the material box 11, when it is necessary to fertilize the crops with multiple ridge spacing, the partition 12 is placed on one side of the material discharge port 15, the fixing frame 3 is connected to the traction device, and the eighth sprocket 101 and the fourth sprocket 53 are driven by the driving motor 100 to achieve the contact between the roller 50 in the first material discharge driving structure 5 and the soil. When the roller 50 rolls, the third sprocket 52 on one side of the roller 50 is connected to the first sprocket 22 through a chain (not shown). Then, the first sprocket 22 is connected to the second sprocket 23 by a chain (not shown), so that the two square rods 24 of the first sprocket 22 and the second sprocket 23 installed simultaneously drive the dial wheels 21 inside the multiple lower hoppers 20 to rotate, so as to transport the fertilizer in the material box 11 to the discharge port at the bottom of the lower hopper 20. During the transportation process, the connecting rod 26 can also be driven to rotate by the adjusting rod 25 to adjust the distance between the adjusting plate 27 of the connecting rod 26 and the discharge port, thereby effectively adjusting the flow rate of the fertilizer;

[0068] When fertilizing with multiple ridge spacing, through the connection between the third sprocket 52 and the first sprocket 22, and the connection between the first sprocket 22 and the second sprocket 23, when the roller 50 rolls on the land, the first sprocket 22 and the second sprocket 23 drive the square rod 24 provided through the lower hopper 20 to drive the thumb wheel 21 to transfer the selenium-rich fertilizer in the material box 11 to the discharge port at the bottom of the lower hopper 20. When transmitting, an adjustment plate 27 is also provided between the thumb wheel 21 and the discharge port at the bottom of the lower hopper 20. The adjustment plate 27 is installed with the connecting rod 26, and the outside of the connecting rod 26 is fixedly installed with the adjustment rod 25. In this way, when fertilizing, the connecting rod 26 is driven to rotate by the adjustment rod 25, thereby effectively realizing the spacing between the adjustment plate 27 and the discharge port, thereby effectively adjusting the fertilizer flow rate up and down;

[0069] The fertilizer is transferred from the discharge port at the bottom of the lower hopper 20 to the lower feed pipe 43 through the conveying pipe. The lower feed pipe 43 is installed on the rear side of the arc frame 41, and a plow 40 is arranged on the front side of the arc frame 41. The bottom of the plow 40 is lower than the bottom of the arc frame 41. In this way, when the traction device drives the fixed frame 3 to move forward, the plow 40 can open the soil for ditching, and the fertilizer inside the lower feed pipe 43 can be applied to the groove, thereby effectively reducing the nutrient loss caused by the volatilization of the selenium-rich fertilizer, thereby effectively ensuring the improvement of the soil by the selenium-rich fertilizer;

[0070] When fertilizing crops with a single ridge spacing, the eighth sprocket 101 drives the fourth sprocket 53 to rotate by driving the motor 100. At this time, the roller 50 tilts upward under the action of the support plate 51 to separate the roller 50 from the soil. In this way, when the traction device drives the fixed frame 3 to work forward, the third sprocket 52 on one side of the roller 50 cannot effectively realize the rotation between the first sprocket 22 and the second sprocket 23, thereby effectively preventing the selenium-rich fertilizer from entering the lower hopper 20. When fertilizing crops with a single ridge spacing, the partition 12 is taken out to realize that the selenium-rich fertilizer in the material box 11 is transmitted to the lower material port 15 through the dragon roller 14;

[0071] When fertilizing at a single ridge spacing, the driving motor 100 drives the eighth sprocket 101 to rotate, and at the same time, the screw rod 102 cooperates with the fixed rod 61 to realize that the fixed rod 61 moves along the double round head slide 60 through the roller to the end away from the fixed frame 3 where the first fertilizing assembly 4 is installed. When the fixed rod 61 moves, the pull rod 62 and the carrier 63 are flipped 90 degrees, so that the soil turning assembly 7, the second fertilizing assembly 8 and the soil covering assembly 9 are moved to the working position, so as to realize the fertilization effect on the crops at a single ridge spacing;

[0072] When fertilizing, the fixed frame 3 realizes the tilling operation of the tilling wheel 70 through the carrier 63. When the tilling wheel 70 rolls, one of the fifth sprockets 72 installed between the tilling wheel 70 and the hanger 71 is connected to the sixth sprocket 88 installed on the rotating rod 86 through a chain (not shown), so that the sixth sprocket 88 drives the rotating rod 86 to rotate. At the same time, two 90° shifting blocks 87 installed on the rotating rod 86 rotate. When the two shifting blocks 87 rotate, the shifting blocks 87 and the two L-shaped moving frames on one side are connected. 85 alternately contact and extrude, so that the two L-shaped moving frames 85 drive the two tooth plates 84 to slide along the C-shaped block 89. During the alternating sliding of the two tooth plates 84, the tooth plates 84 mesh with the gears 83, thereby effectively supporting the rotating shaft 81 through the gears 83 to drive the top swing cylinder 80 to swing left and right. The feed port at the top of the swing cylinder 80 is connected to the bottom of the discharge port 15 through the conveying pipe, so that the swing cylinder 80 evenly spreads the selenium-rich fertilizer in the groove opened by the tiller wheel 70 during the swinging process.

[0073] A soil covering component 9 is provided on the rear side of the second fertilizing component 8, through which the selenium-rich fertilizer spread by the swing drum 80 is covered with soil. When covering the soil, another fifth sprocket 72 on one side of the soil-turning wheel 70 is connected with the seventh sprocket 97, and the second bevel gear 96 coaxially arranged on the seventh sprocket 97 is meshed with the first bevel gear 94 installed on the rotating shaft 90, so that the rotating shaft 90 drives the soil covering plate 92 to rotate effectively, thereby covering the selenium-rich fertilizer with soil.
