Abstract
Description
Technical Field
[0001] This utility model relates to the field of fertilizer production, and in particular to a weighing and measuring device for fertilizer proportioning. Background Technology
[0002] Fertilizer formulation refers to the process of mixing different types of fertilizers in specific proportions according to factors such as crop growth needs, soil nutrient status, and planting goals to form compound fertilizers or mixed fertilizers that meet specific fertilization needs. Different crops have significantly different nutrient requirements at different growth stages. Reasonable formulation can ensure that crops absorb fertilizer as needed, avoid nutrient deficiency or nutrient excess, thereby increasing yield and improving quality. Fertilizer formulation weighing and measuring devices are equipment used to accurately measure and proportion fertilizer raw materials, ensuring that the various components in the fertilizer meet the predetermined proportions. They are widely used in the fertilizer formulation process in agricultural production.
[0003] First, the proportioning component completes the precise proportioning of the raw materials. After the proportioning is completed, the fertilizer falls into the mixing chamber for mixing. After the raw materials are mixed in the mixing chamber, the fertilizer is discharged from the discharge chamber. Through the coordination of the controller, the precise proportioning of raw materials is achieved, ensuring the fertilizer proportioning accuracy and the stability of the device.
[0004] After the fertilizer is mixed and proportioned, the fertilizer may cause blockage at the discharge port during discharge. This will prevent one or more fertilizer raw materials from being discharged completely according to the preset weight, resulting in the actual discharge amount being less than the weighed value. This directly breaks the preset proportion. The blocked fertilizer raw materials may absorb moisture, clump, and deteriorate due to prolonged retention. They need to be treated as waste during cleaning, resulting in waste of raw materials. Utility Model Content

The feeding hopper is fixedly connected above the mixing hopper, the storage hopper is fixedly connected above the feeding hopper, the feed inlet is fixedly connected above the storage hopper, and a solenoid valve is fixedly connected to one side of the feed inlet.
[0009] Preferably, the mixing assembly also includes a support plate, a second motor, a double-acting lead screw, and a fixing rod. The support plate is fixedly connected to the top of the mixing chamber. The second motor is installed on the outer side of the support plate, and the double-acting lead screw is installed on the inner side of the support plate. The double-acting lead screw is connected to the output end of the second motor. A fixing rod is fixedly connected to one side of the support plate.
[0010] Preferably, the proportioning assembly also includes a first sealing plate, a sealing strip, a load cell, and a second sealing plate.

[0013] The beneficial effects of this utility model are as follows: Through ingenious structural design, this utility model uses a starting motor to drive a pulley to rotate, which in turn drives a transmission belt. The transmission belt then drives a second pulley to rotate, which in turn drives a fixed block inside the second pulley to rotate. This allows the fixed frame to rotate circumferentially around the inner wall of the discharge hopper.

Detailed Implementation
[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please see Figures 1-5This utility model provides an embodiment: a weighing and measuring device for fertilizer proportioning, including a mixing chamber 101, a base 104, and an anti-blocking component. A discharge chamber 102 is fixedly connected to the lower part of the mixing chamber 101, and a support 103 is fixedly connected to the outer side of the discharge chamber 102. An anti-blocking component is provided below the discharge chamber 102. The base 104 is fixedly connected to one side of the support 103. A motor 105 is fixedly connected to the upper part of the base 104. A pulley 106 is rotatably connected above the motor 105. An annular plate 107 is fixedly connected to the lower part of the discharge chamber 102. Annular grooves are formed on both sides of the annular plate 107. A pulley 108 is rotatably connected inside the annular grooves. A transmission belt 109 is drivingly connected above the pulley 106 and pulley 108. A fixing block 110 is fixedly connected inside the pulley 108. A fixing frame 111 is fixedly connected above the fixing block 110. A cleaning scraper is fixedly connected to one side of the fixing frame 111. A stirring rod 113 is fixedly connected to the other side of the fixed frame 111. The starting motor 105 drives the pulley 106 to rotate, which in turn drives the transmission belt 109 to rotate. The transmission belt 109 drives the pulley 108 to rotate, which in turn drives the fixed block 110 inside the pulley 108 to rotate. The rotation of the fixed block 110 drives the fixed frame 111 to rotate around the inner wall of the discharge bin 102. The rotation of the fixed frame 111 drives the stirring rod 113 to rotate, thereby stirring and dispersing the fertilizer discharged from the discharge bin 102, ensuring that the fertilizer falls evenly and preventing fertilizer accumulation that could cause blockage in the discharge bin 102. The rotation of the fixed frame 111 drives the cleaning scraper 112 to scrape off any residual fertilizer on the inner wall of the discharge bin 102. After the work is completed, the residual fertilizer on the inner wall of the discharge bin 102 can be scraped off to clean the inner wall.
[0022] Please see Figures 1-3In this embodiment, a controller 201 is fixedly connected to the outer side of the support 103, and a proportioning component is fixedly connected above the mixing chamber 101. Two proportioning components are provided, each including a feeding chamber 202, a storage chamber 203, a feed inlet 204, and a solenoid valve 205. The feeding chamber 202 is fixedly connected above the mixing chamber 101, the storage chamber 203 is fixedly connected above the feeding chamber 202, the feed inlet 204 is fixedly connected above the storage chamber 203, and a solenoid valve 205 is fixedly connected to one side of the feed inlet 204. The proportioning component also includes a support plate 206. The mixing chamber 101 includes a second motor 207, a double-acting lead screw 208, and a fixing rod 209. A support plate 206 is fixedly connected above the mixing chamber 101. The second motor 207 is mounted on the outer side of the support plate 206, and the double-acting lead screw 208 is mounted on the inner side of the support plate 206. The double-acting lead screw 208 is connected to the output end of the second motor 207. A fixing rod 209 is fixedly connected to one side of the support plate 206. The proportioning assembly also includes a first sealing plate 210, a sealing strip 211, a weighing sensor 212, and a second sealing plate 213. The first sealing plate 210 is threaded onto one side of the double-acting lead screw 208. A weighing sensor 212 is fixedly connected to the top of 210. A sealing strip 211 is fixedly connected to one side of the weighing sensor 212, and a sealing plate 213 is threaded to the other side of the bidirectional lead screw 208. Fertilizer is placed into the storage silo 203 through the feed inlet 204, and the weighing sensor 212 weighs the fertilizer. The solenoid valve 205, the weighing sensor 212, the motor 207, and the controller 201 are electrically connected. When the weighing sensor 212 detects that the weight is close to the preset value, the controller 201 sends a signal in advance to close the solenoid valve 205. 201 sends a start signal to motor 207, which in turn drives the bidirectional lead screw 208 to rotate. The rotation of the bidirectional lead screw 208 causes the sealing plate 210, sealing plate 213, and weighing sensor 212 to move in opposite directions to both sides, thereby transporting the fertilizer in storage bin 203 through feeding bin 202 into the mixing bin 101. After the fertilizer has completely fallen into the mixing bin 101, controller 201 instructs motor 207 to rotate in the opposite direction, and the bidirectional lead screw 208 drives the weighing sensor 212, sealing plate 210, and sealing plate 213 to close.
[0023] Please see Figures 3-5In this embodiment, a stirring device 301 is provided inside the mixing chamber 101. A crossbeam 302 is fixedly connected above the stirring device 301. A cleaning scraper 303 is fixedly connected to one side of the crossbeam 302. The cleaning scraper 303 abuts against the inner wall of the mixing chamber 101. The controller 201 is electrically connected to the stirring device. By adjusting the controller 201, the stirring device 301 is started to rotate, which in turn drives the crossbeam 302 to rotate. The rotation of the crossbeam 302 drives the cleaning scraper 303 to rotate, thereby scraping off the fertilizer residue on the inner wall of the mixing chamber 101 and cleaning the inside of the mixing chamber 101.
[0024] During operation, fertilizer is fed into the storage silo 203 through the feed inlet 204. The fertilizer is weighed by the load cell 212. The controller 201 is electrically connected to the solenoid valve 205, load cell 212, and motor 207. When the load cell 212 detects that the weight is close to a preset value, the controller 201 sends a signal to close the solenoid valve 205. The controller 201 then sends a start signal to the motor 207, causing the motor 207 to rotate, which in turn drives the bidirectional lead screw 208 to rotate. Sealing plate 210, sealing plate 213, and weighing sensor 212 move in opposite directions to both sides, thereby transporting the fertilizer in storage silo 203 through feeding silo 202 to the interior of mixing silo 101. Once the fertilizer has completely fallen into mixing silo 101, controller 201 instructs motor 207 to rotate in the opposite direction. The bidirectional lead screw 208 drives weighing sensor 212, sealing plate 210, and sealing plate 213 to close. Starting motor 105 drives pulley 106 to rotate, which in turn drives transmission belt 109 to rotate. The transmission belt 109 rotates, driving the pulley 108 to rotate. The rotation of the pulley 108 causes the fixed block 110 inside it to rotate. The rotation of the fixed block 110 causes the fixed frame 111 to rotate circumferentially around the inner wall of the discharge hopper 102. The rotation of the fixed frame 111 causes the stirring rod 113 to rotate, thus stirring and dispersing the fertilizer discharged from the discharge hopper 102. This ensures the fertilizer falls evenly and prevents fertilizer accumulation that could clog the discharge hopper 102. The cleaning scraper 112 is driven to scrape off the fertilizer residue on the inner wall of the discharge bin 102. After the work is completed, the fertilizer residue on the inner wall of the discharge bin 102 can be scraped off and the inner wall can be cleaned. The controller 201 is electrically connected to the mixing device. By adjusting the controller 201, the mixing device 301 is started to rotate, which drives the cross frame 302 to rotate. The rotation of the cross frame 302 drives the cleaning scraper 303 to rotate, thereby scraping off the fertilizer residue on the inner wall of the mixing bin 101 and cleaning the inside of the mixing bin 101.
[0025] Through the above steps, the starting motor 105 drives the pulley 106 to rotate, which in turn drives the transmission belt 109 to rotate, which in turn drives the pulley 108 to rotate. The rotation of the pulley 108 drives the fixed block 110 inside the pulley 108 to rotate, which in turn drives the fixed frame 111 to rotate around the inner wall of the discharge bin 102. The rotation of the fixed frame 111 drives the stirring rod 113 to rotate, thereby stirring and dispersing the fertilizer discharged from the discharge bin 102, ensuring that the fertilizer falls evenly and preventing fertilizer accumulation that could cause blockage in the discharge bin 102. The rotation of the fixed frame 111 drives the cleaning scraper 112 to scrape off any residual fertilizer on the inner wall of the discharge bin 102. After the work is completed, the residual fertilizer on the inner wall of the discharge bin 102 can be scraped off to clean the inner wall.
