Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and more specifically, it relates to an agricultural machinery fertilizing device. Background Art

[0002] Agricultural fertilization is an essential and important measure in agricultural planting, and is an important guarantee for yield and economic benefits. When the nutrient elements in the soil cannot meet the nutritional needs of crop growth and development, it is necessary to artificially supplement nutrient elements to the crops.

[0003] Existing agricultural fertilizing machines are different from traditional manual fertilizing methods. Traditional manual fertilization has low efficiency. Existing agricultural fertilizing devices are often on mobile devices (agricultural machinery vehicles, tractors) and fertilize while moving in the farmland, with relatively high efficiency. The fertilizer is first filled in the storage bin, and the bottom end of the storage bin intermittently discharges the fertilizer through an electronic valve or an intermittent valve. However, in the actual fertilization process, different types of fertilizers will all partially adhere to the inside of the fertilizer storage bin, reducing the total amount of fertilization. Moreover, if the fertilizer is not cleaned in time, it will deteriorate after long-term fermentation, affecting the next fertilization process. At the same time, during the fertilization time, the sticky fertilizer is prone to caking, resulting in the caked fertilizer being unable to pass through the intermittent valve and blocking the feeding port.

[0004] Therefore, in order to solve the above technical problems, the present application proposes an agricultural machinery fertilizing device. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide an agricultural machinery fertilizing device, which makes the fertilizer bin vibrate when the fertilizer adheres by reciprocatingly hammering the counterweight block above and below, loosens the fertilizer adhering to the bin wall, and cooperates with the scraping component and the crushing component to make the adhered fertilizer and the caked fertilizer both pass through the electric feeding valve for fertilization, solving the technical problems of fertilizer adhering in the fertilizer bin and fertilizer caking resulting in low fertilization efficiency.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An agricultural machinery fertilizing device, including a fertilizer bin, a feeding port provided on the fertilizer bin, a discharging bin provided at the lower part of the fertilizer bin, and an electric feeding valve provided at the discharging port of the discharging bin, and further including:

[0007] A transmission bin provided above the fertilizer bin, symmetrically provided with a vibration component for vibrating the fertilizer bin to assist in discharging inside the transmission bin. The vibration component includes a counterweight block that completes a reciprocating up and down hammering action inside the fertilizer bin, and a bearing block is provided inside the fertilizer bin corresponding to the lower part of the counterweight block;

[0008] A scraping assembly disposed inside the fertilizer bin for scraping the fertilizer adhering to the inner wall of the fertilizer bin. The scraping assembly includes an axial scraping plate disposed inside the fertilizer bin and rotating in contact with the inner wall of the fertilizer bin, and an inclined scraping plate disposed inside the feeding bin and in contact with the inner wall of the feeding bin. A crushing assembly for crushing caked fertilizer is further provided below the scraping assembly.

[0009] Preferably, a driving motor is fixedly installed inside the transmission bin. A driving steering gear is provided at the output end of the driving motor. The oscillation assembly further includes a support frame disposed on the bottom surface of the transmission bin. A horizontal shaft is rotatably installed on the support frame. A driven steering gear is provided at one end of the horizontal shaft close to the driving steering gear. A runner is provided at the other end of the horizontal shaft. A fixed shaft is provided on the runner. A rotating shaft is rotatably installed at the end of the fixed shaft. A shock spring is fixedly connected to the lower end of the rotating shaft. The lower end of the shock spring is fixedly connected to an impact rod. The lower end of the impact rod is fixedly connected to a counterweight.

[0010] Preferably, there are two driven steering gears, which respectively engage the tooth flanks on both sides of the driving steering gear to complete the action of rotating from the longitudinal axis of the driving steering gear to the transverse axes of the two driven steering gears.

[0011] Preferably, the fixed shaft is disposed at the edge of the runner away from the center of the circle.

[0012] Preferably, a buffer mechanism is provided between the fertilizer bin and the transmission bin. The fertilizer bin and the transmission bin are elastically connected through the buffer mechanism.

[0013] Preferably, the buffer mechanism includes a telescopic ring disposed at the bottom of the transmission bin. The telescopic ring is a double-layer ring. A buffer spring is provided in the double-layer sandwich of the telescopic ring. One end of the buffer spring is fixedly connected to the bottom end of the transmission bin, and the other end is fixedly connected to the top end of the fertilizer bin. A moving groove adapted to the telescopic ring is opened inside the fertilizer bin near the transmission bin end. The telescopic ring moves in the moving groove, and a T-shaped block is provided at the bottom end of the telescopic ring. A T-shaped space is provided at the bottom of the moving groove.

[0014] Preferably, the scraping assembly further includes a rotating shaft. The top end of the rotating shaft is fixedly connected to the output end of the driving motor. Transfer rods are symmetrically installed on the rotating shaft. The two axial scraping plates are respectively fixedly connected to the transfer rods. The inclined scraping plate has an inclination, and the inclined scraping plate is supported by the transfer rods on the rotating shaft and is in contact with the inner wall of the feeding bin.

[0015] Preferably, the axial scraping plate is in the shape of a shovel, with a crescent-shaped cross-section, and the direction of the rotational movement is the direction pointed by the tip of the shovel shape.

[0016] Preferably, a plurality of the crushing rods are arranged along the circumference of the bottom of the rotating shaft, and multiple groups of the plurality of crushing rods are longitudinally arranged along the rotating shaft.

[0017] Preferably, the lengths of the multiple groups of crushing rods are different, specifically decreasing gradually along the inclined direction of the feeding bin.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, by reciprocatingly hammering the counterweight blocks on the bearing blocks up and down, the fertilizer bin vibrates when the fertilizer sticks. The caking adhesion force of the solid granular fertilizer is relatively large, and the counterweight blocks on both sides inside the fertilizer bin vibrate simultaneously, increasing the vibration force, so that the caked solid granular fertilizer becomes loose. At this time, when the shoveled axial scraping plate is used for scraping, the fertilizer can be scraped more easily. When the liquid fertilizer adheres to the wall of the fertilizer bin, the counterweight blocks hammering the bearing blocks alternately cause the bin wall to vibrate rapidly, so that the liquid fertilizer flows rapidly downward on the bin wall. The inclined scraping plate located in the feeding bin simultaneously scrapes the wall of the feeding bin to prevent the fertilizer from falling on the wall of the feeding bin and continuing to stick. Similarly, for the caked fertilizer, multiple groups of crushing rods are hierarchically arranged in the feeding bin, and the multiple groups of crushing rods can crush the caked fertilizer to prevent the caked fertilizer from blocking the electric feeding valve, improving the fertilization efficiency of the fertilization machine by 15%-25%.

[0020] 2. In the present invention, through the limitation of the T-shaped block at the bottom of the moving groove, the telescopic ring can move inside the moving groove. At the same time, the action of the telescopic spring provides a buffer space between the transmission bin and the fertilizer bin. When the fertilizer bin vibrates, the vibration is not directly transmitted to the inside of the transmission bin through the telescopic elastic force of the multiple telescopic springs, protecting the stable operation of the internal mechanism components and reducing the failure rate of the device.

[0035] Example 1:

[0036] As Figures 1 - 12 shown, the present invention provides an agricultural machinery fertilizing device, including a fertilizer bin 1, a feed inlet 5 provided on the fertilizer bin 1, a feeding bin 3 provided at the lower part of the fertilizer bin 1, and an electric feeding valve 4 provided at the feeding port of the feeding bin 3;

[0037] It should be noted that the fertilizer bin 1 is externally connected to a mobile device, and the mobile device can be a vehicle carrier such as an agricultural vehicle that moves in the farmland. The electric feeding valve 4 is an intermittently operable valve that can be automatically opened and closed in the prior art. Through the intermittent valve and the pressure ejection device inside the electronic valve, the fertilizer can be discharged at intervals for fertilization. The staff can fill the fertilizer into the fertilizer bin 1 through the feed inlet 5;

[0038] Further included are: a transmission bin 2 disposed above the fertilizer bin 1, a drive motor 9 fixedly installed inside the transmission bin 2, a driving steering gear 601 provided at the output end of the drive motor 9, an oscillation assembly 6 symmetrically disposed inside the transmission bin 2 for assisting in discharging materials from the fertilizer bin 1 by oscillation. The oscillation assembly 6 includes a counterweight 609 that performs a reciprocating up-and-down hammering action inside the fertilizer bin 1. A bearing block 610 is provided inside the fertilizer bin 1 corresponding to the lower side of the counterweight 609. The oscillation assembly 6 further includes a support frame 605 disposed on the bottom surface of the transmission bin 2. A horizontal shaft 603 is rotatably installed on the support frame 605. It should be noted that a bearing is provided on the support frame 605, and the horizontal shaft 603 is rotatably installed on the support frame 605 through the bearing. One end of the horizontal shaft 603 close to the driving steering gear 601 is provided with a driven steering gear 602. There are two driven steering gears 602, which respectively engage with the tooth flanks on both sides of the driving steering gear 601 to complete the action of rotating from the longitudinal axis of the driving steering gear 601 to the transverse axes of the two driven steering gears 602. The other end of the horizontal shaft 603 is provided with a runner 604. A fixed shaft 611 is provided on the runner 604. The fixed shaft 611 is disposed at the edge of the runner 604 away from the center of the circle. The end of the fixed shaft 611 is rotatably installed with a rotating shaft 606. The lower end of the rotating shaft 606 is fixedly connected with an oscillation spring 607. The lower end of the oscillation spring 607 is fixedly connected with an impact rod 608. The lower end of the impact rod 608 is fixedly connected with the counterweight 609;

[0039] Such as Figures 2 - 5 , by driving the driving steering gear 601 to rotate through the drive motor 9, the rotation of the longitudinal axis of the driving steering gear 601 drives the rotation of the transverse axes of the two driven steering gears 602. The horizontal shaft 603 fixedly connected with the driven steering gears 602 is supported by the support frame 605 and is rotationally connected through a bearing to drive the runner 604 to rotate, so that the fixed shaft 611 makes a circular motion around the center of the runner 604. At this time, the rotating shaft 606 rotationally connected with the fixed shaft 611 also rotates around the center of the runner 604. At the same time, through the pulling of the oscillation spring 607, the rotating shaft 606 does not rotate itself, and the part connected to the oscillation spring 607 always faces the impact rod 608. It should be noted that such as Figure 3 And Figure 10 , a limit groove 612 is opened at the bottom of the transmission bin 2, which restricts the lateral offset of the impact rod 608, making it only able to perform a reciprocating up-and-down motion. The reciprocating up-and-down impact rod 608 can drive the counterweight 609 to impact the bearing block 610 inside the fertilizer bin 1, causing the entire fertilizer bin 1 to oscillate.

[0040] A scraping component 7 is arranged inside the fertilizer bin 1 for scraping the fertilizer sticking to the inner wall of the fertilizer bin 1. The scraping component 7 includes an axial scraping plate 702 arranged inside the fertilizer bin 1 and rotating along the inner wall of the fertilizer bin 1, and an inclined scraping plate 704 arranged inside the blanking bin 3 and fitting the inner wall of the blanking bin 3. The axial scraping plate 702 is shovel-shaped, with a crescent-shaped cross-section, and the direction of the rotational movement is the direction pointed by the tip of the shovel shape. The scraping component 7 further includes a rotating shaft 701. The top of the rotating shaft 701 is fixedly connected to the output end of the driving motor 9. Transmission rods 703 are symmetrically installed on the rotating shaft 701, and the two axial scraping plates 702 are respectively fixedly connected to the transmission rods 703. The inclined scraping plate 704 has an inclination, and the inclined scraping plate 704 is supported by the transmission rod 703 on the rotating shaft 701 and fits the inner wall of the blanking bin 3. A crushing component 8 for crushing the caked fertilizer is further arranged below the scraping component 7. A plurality of crushing rods 801 are arranged along the circumference of the bottom of the rotating shaft 701. A plurality of groups of crushing rods 801 are arranged longitudinally along the rotating shaft 701 as a group. The lengths of the multiple groups of crushing rods 801 are different, specifically decreasing gradually along the inclined direction of the blanking bin 3.

[0041] It should be noted that while the driving motor 9 drives the active steering gear 601 to rotate, it also drives the rotating shaft 701 to rotate. When the rotating shaft 701 rotates, it drives the transmission rod 703 on its surface to rotate, thereby driving the axial scraping plate 702 to scrape the fertilizer on the inner wall of the fertilizer bin 1. Since the axial scraping plate 702 is shovel-shaped, it can scrape the caked fertilizer on the inner wall better than the traditional scraping plate. At this time, the inclined scraping plate 704 located in the blanking bin 3 simultaneously scrapes the inner wall of the blanking bin 3 to prevent the fertilizer from sticking to the inner wall of the blanking bin 3 again. Similarly, for the caked fertilizer, multiple groups of crushing rods 801 are hierarchically arranged in the blanking bin 3, and the multiple groups of crushing rods 801 can crush the caked fertilizer to prevent the caked fertilizer from blocking the electric blanking valve 4.

[0042] It should be noted that the experimental data results show that for the fertilizing device without using this device in the prior art, after three fertilizations, sticky fertilizer remains in the fertilizer bin 1 each time, and the fertilization rates for each fertilization are 72%, 81%, and 76% respectively. After using this fertilizing device for three fertilizations, the remaining fertilizer in the fertilizer bin 1 decreases. The fertilization rates for the three fertilizers are 98%, 95%, and 97% respectively, increasing the fertilization rate of the fertilizing device by 15% - 25%.

[0043] Moreover, the fertilizer in this embodiment can be solid granular waste, liquid fertilizer, and powdered fertilizer. For the adhesion of solid granular fertilizer to the inner wall of the fertilizer bin 1, the axial scraping plate 702 of the scraping assembly 7 scrapes the adhered fertilizer on the inner wall. The counterweight 609 in the vibration assembly 6 continuously hammers the bearing block 610, causing the inner wall of the fertilizer bin 1 to vibrate, so that the adhered solid granular fertilizer becomes loose. At this time, when the shovel-shaped axial scraping plate 702 is used for scraping, it will be easier to scrape the fertilizer. For liquid fertilizer, the counterweight 609 hammering the bearing block 610 can increase the flow rate of the liquid fertilizer hanging on the inner wall of the fertilizer bin 1, reducing the adhesion of the liquid fertilizer on the fertilizer bin 1 after being air-dried over time. For powdered fertilizer, it is not easy for the axial scraping plate 702 and the diagonal scraping plate 704 to completely scrape the powder from the inner wall, but through the continuous hammering of the counterweight 609 on the bearing block 610, the powder is shaken off the inner wall and falls into the feeding bin 3, completing the cleaning of the fertilizer.

[0044] In this embodiment, for different required scenarios, the initial positions of the two relative rotating shafts 606 are different during rotation. For example, Figure 11 and Figure 12 as shown, Figure 11 which indicates that the positions of the rotating shafts 606 are the same during rotation in this process. At this time, for the scenario that requires strong vibration, such as when the solid granular fertilizer caking adhesion force is relatively large, the counterweights 609 on both sides inside the fertilizer bin 1 vibrate simultaneously to increase the vibration force. Figure 12 which indicates that the initial positions of the rotating shafts 606 are different during rotation in this process. The two rotating shafts 606 are located at opposite positions on the circumference of the runner 604. At this time, for the scenario that requires rapid vibration, such as when the liquid fertilizer hangs on the inner wall of the fertilizer bin 1, the counterweights 609 that alternately hammer the bearing block 610 cause the inner wall to vibrate rapidly, so that the liquid fertilizer drops rapidly, and at the same time, it prevents the electric feeding valve 4 from being blocked due to excessive accumulation of fertilizer.

[0045] By reciprocatingly hammering the counterweight 609 of the bearing block 610 up and down, the fertilizer bin 1 is shaken when the fertilizer sticks. The caking adhesion force of the solid granular fertilizer is relatively large. The counterweights 609 on both sides inside the fertilizer bin 1 are shaken simultaneously, increasing the shaking force, so that the caked solid granular fertilizer becomes loose. When the shovel-shaped axial scraping plate 702 scrapes at this time, it will be easier to scrape the fertilizer. When the liquid fertilizer adheres to the wall of the fertilizer bin 1, the counterweight 609 that alternately hammers the bearing block 610 causes the bin wall to vibrate rapidly, so that the liquid fertilizer flows rapidly downward on the bin wall. The inclined scraping plate 704 located in the blanking bin 3 scrapes the wall of the blanking bin 3 at the same time to prevent the fertilizer from adhering to the wall of the blanking bin 3 and continuing to stick. Similarly, for the caked fertilizer, multiple groups of crushing rods 801 are hierarchically arranged in the blanking bin 3. The multiple groups of crushing rods 801 can crush the caked fertilizer to prevent the caked fertilizer from blocking the electric blanking valve 4, increasing the fertilization efficiency of the fertilization machine by 15%-25%.

[0046] Working principle: When the staff finds that the fertilizer inside the fertilizer bin 1 decreases, the driving motor 9 drives the active steering gear 601 to rotate. The longitudinal axis rotation of the active steering gear 601 drives the transverse axis rotation of the driven steering gears 602 on both sides. And the cross shaft 603 fixedly connected to the driven steering gear 602 is supported by the support frame 605 and is rotationally connected through a bearing and can drive the runner 604 to rotate, so that the fixed shaft 611 makes a circular motion around the center of the runner 604. At this time, the rotating shaft 606 rotationally connected to the fixed shaft 611 also rotates around the center of the runner 604. At the same time, due to the pulling of the shock spring 607, the rotating shaft 606 does not rotate itself, and the part connecting the shock spring 607 always faces the impact rod 608. It should be noted that, as Figure 3 and Figure 10 , the limit groove 612 is opened at the bottom of the transmission bin 2, which restricts the lateral offset of the impact rod 608 so that it can only move up and down reciprocally. The impact rod 608 that moves up and down reciprocally can drive the counterweight 609 to impact the bearing block 610 inside the fertilizer bin 1, causing the entire fertilizer bin 1 to vibrate;

[0047] While the driving motor 9 drives the active steering gear 601 to rotate, it also drives the rotating shaft 701 to rotate. When the rotating shaft 701 rotates, it drives the transmission rod 703 on its surface to rotate, thereby driving the axial scraping plate 702 to scrape the wall of the fertilizer bin 1 to remove the fertilizer. Since the axial scraping plate 702 is shovel-shaped, for the fertilizer caked on the bin wall, it can scrape better than the traditional scraping plate. At this time, the inclined scraping plate 704 located in the blanking bin 3 scrapes the wall of the blanking bin 3 at the same time to prevent the fertilizer from adhering to the wall of the blanking bin 3 and continuing to stick. Similarly, for the caked fertilizer, multiple groups of crushing rods 801 are hierarchically arranged in the blanking bin 3. The multiple groups of crushing rods 801 can crush the caked fertilizer to prevent the caked fertilizer from blocking the electric blanking valve 4.

A moving groove 11 adapted to the telescopic ring 10 is opened inside one end of the fertilizer bin 1 close to the transmission bin 2.

At the same time, the action of the telescopic spring enables a buffer space between the transmission bin 2 and the fertilizer bin 1. When there is an oscillation in the fertilizer bin 1, the shock is not directly transmitted to the inside of the transmission bin 2 through the telescopic elastic force of multiple telescopic springs, protecting the stable operation of the internal mechanism components and reducing the failure rate of the device.

[0052] Working principle: Through the limitation of the T-shaped block 13 at the bottom of the moving groove 11, the telescopic ring 10 can move inside the moving groove 11.
