Description

Technical Field

[0001] The present invention relates to the technical field of agricultural implements, and particularly relates to a field biogas slurry fertilizing device. Background Art

[0002] With the gradual increase of biogas projects, a large amount of biogas slurry is generated from the anaerobic fermentation of livestock and poultry manure. The problem of biogas slurry is becoming increasingly prominent. Biogas slurry is a highly polluting substance and cannot be directly discharged into the environment. Building post-treatment facilities for up-to-standard treatment greatly increases the construction and operation costs. Therefore, there is a serious problem of digestion. In fact, biogas slurry contains rich nitrogen, phosphorus, potassium, amino acids, rich trace elements, B vitamins, various hydrolases, organic acids, humic acids and other bioactive substances, and is a very good organic fertilizer, which can stimulate crop growth, enhance crop stress resistance and improve product quality. Biogas slurry can be used as organic fertilizer to achieve secondary utilization of resources.

[0003] Biogas slurry may contain biogas residues. Biogas slurry as fertilizer is usually a fluid fertilizer. However, in the current fertilizer market, most fertilizer applicators do not have the function of quantitatively applying fluid fertilizer. Therefore, it is necessary to design a field biogas slurry fertilizing device that can apply biogas slurry. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a field biogas slurry fertilizing device.

[0005] The above technical object of the present invention is achieved by the following technical solutions: A field biogas slurry fertilizing device includes a mounting frame, moving wheels arranged at the bottom of the mounting frame, a support rod fixed to the top of the mounting frame, a mounting plate fixed to the upper end of the support rod, a support frame fixed to the top of the mounting plate, and a storage bucket arranged on the support frame. A rotating disk capable of rotating around the axis of the mounting plate is arranged on the mounting plate. A driving member for driving the rotating disk to rotate is arranged on the mounting plate. A plurality of measuring cylinders evenly distributed about the axis of the rotating disk are arranged on the rotating disk. The orthogonal projection of the axis of the storage bucket on the rotating disk is located on the circle where the axes of the plurality of measuring cylinders are located. The bottom of the storage bucket is funnel-shaped. An electromagnetic valve is arranged on the storage bucket. The outer diameter of the bottom of the storage bucket is smaller than the inner diameter of the measuring cylinder. A bottom cover cooperating with the measuring cylinder is rotatably installed at a position near the bottom of the inner wall of the measuring cylinder. An outlet through hole with a diameter larger than the outer diameter of the measuring cylinder is arranged on the mounting plate. The bottom surface of the bottom cover abuts against the top of the mounting plate when the bottom cover is closed.

[0006] By adopting the above technical solution, a plurality of measuring cylinders are provided and are evenly distributed about the axis of the rotating disk. The measuring cylinders have a certain volume, and the specifications of the plurality of measuring cylinders are the same. After the bottom cover is closed, it abuts against the top of the mounting plate. The measuring cylinders can measure the biogas slurry fertilizer flowing out of the storage bucket, so as to facilitate the quantitative addition of biogas slurry fertilizer by the biogas slurry fertilizing device. During fertilization, the driving member drives the rotating disk to rotate, and the rotating disk drives the measuring cylinders to rotate. When the bottom cover at the bottom of the measuring cylinder corresponds to the discharge through hole, the biogas slurry fertilizer flows out of the discharge through hole and performs the fertilization action. The bottom cover of the measuring cylinder not corresponding to the discharge through hole abuts against the top of the mounting plate, enhancing the stability of the biogas slurry fertilizer on the rotating disk. Repeatedly adding biogas slurry fertilizer into the empty measuring cylinder can complete the actions of quantitative storage and fertilization of biogas slurry fertilizer.

[0007] Further, the driving member is a motor fixed to the bottom of the mounting plate and coaxially arranged with the rotating disk. At a position near the top of the inner wall of the measuring cylinder, a lower sensor for monitoring the liquid level height in the measuring cylinder and an upper sensor for sensing the bottom of the storage bucket are sequentially embedded. A controller and a storage battery electrically connected to the motor are fixed to the top of the mounting frame. The controller is electrically connected to the solenoid valve, the motor, the lower sensor, and the upper sensor.

[0008] By adopting the above technical solution, the lower sensor monitors the liquid level height of the biogas slurry in the measuring cylinder and transmits the liquid level height information to the controller in the form of an electrical signal. When the real-time liquid level height approaches the preset measurement value, the controller controls the feeding speed of the solenoid valve. When the real-time liquid level height reaches the preset measurement value, the solenoid valve closes, and the motor starts and drives the rotating disk to rotate, causing the empty measuring cylinder to rotate. The upper sensor senses the bottom of the storage bucket and transmits the information to the controller in the form of an electrical signal. A position sensing device such as a proximity switch can be used. When the upper sensor monitors that the position of the measuring cylinder corresponds to the bottom opening position of the storage bucket, the controller controls the motor to stop running and the solenoid valve to open, and the biogas slurry in the storage bucket enters the empty measuring cylinder to complete the feeding. Repeating the above actions can simultaneously complete the biogas slurry adding action of the empty measuring cylinder and the biogas slurry fertilizing action in the field.

[0009] Further, a gap is left between the bottom of the rotating disk and the top of the mounting plate, and a scraper that fits the top of the mounting plate is fixed to the bottom of the rotating disk.

[0010] By adopting the above technical solution, after the motor works, it drives the rotating disk to rotate, and the rotating disk drives the scraper to move synchronously, thereby cleaning a small amount of biogas slurry that leaks from the gap between the bottom cover and the inner wall of the measuring cylinder to the top of the mounting plate.

[0011] Further, a plurality of liquid outlet holes are penetrated through the mounting plate, and the plurality of liquid outlet holes are evenly distributed about the axis of the rotating disk.

[0012] By adopting the above technical solution, the arrangement of the liquid outlet holes facilitates the discharge of a small amount of biogas slurry that leaks from the gap between the bottom cover and the inner wall of the measuring cylinder to the top of the mounting plate.

[0013] Furthermore, the orthographic projection of the multiple liquid outlet holes is located within the mounting frame, and the motor selected is a brake motor.

[0014] By adopting the above technical solution, it avoids the situation that the biogas slurry leaking from the liquid outlet holes at the edge of the mounting plate contaminates the top of the mounting frame. The brake motor can brake the motor through the brake in the case of power failure, power outage or control system failure, achieving rapid stop and having high safety. After the motor stops running, the rotating disk and the measuring cylinder can both maintain a stable state, so that the storage bucket can perform the feeding action on the measuring cylinder.

[0015] Furthermore, a protective cover covering the outside of the driving member is fixed to the bottom of the mounting plate, and heat dissipation holes are provided at the bottom of the protective cover.

[0016] By adopting the above technical solution, the protective cover plays a good protective role for the motor, avoiding the probability of biogas slurry dripping onto the motor and damaging the motor. The heat dissipation holes are arranged at the bottom of the protective cover, which facilitates the heat dissipation of the motor while reducing the probability of biogas slurry entering the inside of the protective cover and causing the motor to rust.

[0017] Furthermore, rounded corners are provided at the intersections between the side wall of the bottom cover and the top and bottom of the bottom cover, and a sealing rubber ring is fixedly sleeved on the side wall of the bottom cover.

[0018] By adopting the above technical solution, the setting of the rounded corners enhances the smoothness of the bottom cover during the rotation around its rotation axis, and the setting of the sealing rubber ring enhances the sealing between the bottom cover and the inner wall of the measuring cylinder, reducing the probability of biogas slurry leakage in the measuring cylinder.

[0019] Furthermore, the moving wheels are moving wheels with brakes, and the top of the mounting plate is treated smoothly.

[0020] By adopting the above technical solution, it is convenient for the staff to move or fix the fertilizing device, and the smoothly treated mounting plate reduces the probability of biogas slurry sticking.

[0021] In summary, the present invention has the following beneficial effects: 1. In this application, the driving member drives the rotating disk to rotate, and repeatedly adding biogas slurry fertilizer into the empty measuring cylinder can complete the actions of quantitative storage and fertilization of biogas slurry fertilizer; 2. In this application, the lower sensor monitors the height of the biogas slurry level in the measuring cylinder and transmits the information on the height of the liquid level to the controller in the form of an electrical signal. When the real-time liquid level height approaches the pre-designed measurement value, the controller controls the feeding speed of the solenoid valve. When the real-time liquid level height reaches the pre-designed measurement value, the solenoid valve closes, the motor starts and drives the rotating disk to rotate, causing the empty measuring cylinder to rotate. The upper sensor senses the bottom of the storage barrel and transmits the information to the controller in the form of an electrical signal. A position sensing device such as a proximity switch can be used. When the upper sensor monitors that the position of the measuring cylinder corresponds to the bottom opening position of the storage barrel, the controller controls the motor to stop running and the solenoid valve to open, and the biogas slurry in the storage barrel enters the empty measuring cylinder to complete the feeding. By repeating the above actions, the biogas slurry addition action for the empty measuring cylinder and the biogas slurry fertilization action in the field can be completed simultaneously.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0025] Such as Figures 1-4As shown in the figure, an embodiment of the present application discloses a field biogas slurry fertilizing device, which includes a mounting frame 1, a mounting plate 2, a storage barrel 3, a rotating disk 4, and a metering cylinder 5. The mounting frame 1 is horizontally arranged. Four fixing rods 11 distributed in a rectangular array are fixed to the bottom of the mounting frame 1. A mobile wheel 12 with a brake is rotatably installed between two fixing rods 11 on the same side. In this embodiment, the mobile wheel 12 is driven electrically. The technology of driving the mobile wheel 12 arranged at the bottom of the fertilizing device to rotate belongs to conventional technology and will not be elaborated here. A plurality of support rods 13 are fixed to the top of the mounting frame 1.

[0026] The mounting plate 2 is a horizontally arranged round rod-shaped structure. The central axis of the mounting plate 2 coincides with the center line of the mounting frame 1. The bottom surface of the mounting plate 2 and the upper ends of a plurality of support rods 13 are fixedly connected together. A support frame 21 is fixed to the top of the mounting plate 2. The top of the storage barrel 3 is cylindrical, and the bottom of the storage barrel 3 is funnel-shaped. The axis of the storage barrel 3 is vertical. The storage barrel 3 is fixed to the support frame 21, and a solenoid valve 31 is arranged at a position near the bottom of the storage barrel 3.

[0027] The rotating disk 4 is arranged above the mounting plate 2. A driving member 6 coaxially arranged with the rotating disk 4 is fixed to the bottom of the mounting plate 2. In this embodiment, the driving member 6 is a hold-brake motor. The upper end of the output shaft of the motor is fixed to the bottom of the rotating disk 4, and the output shaft of the motor is rotatably connected to the mounting plate 2.

[0028] The metering cylinder 5 is a cylindrical structure with a vertical axis. There are a plurality of metering cylinders 5 which are evenly distributed about the axis of the rotating disk 4. The orthographic projection of the axis of the storage barrel 3 on the rotating disk 4 is located on the circle where the axes of a plurality of metering cylinders 5 are located. The outer diameter of the bottom of the storage barrel 3 is smaller than the inner diameter of the metering cylinder 5. A bottom cover 51 matching with the metering cylinder 5 is rotatably installed at a position near the bottom of the inner wall of the metering cylinder 5. An outlet through hole 22 with a diameter larger than the outer diameter of the metering cylinder 5 is arranged on the mounting plate 2. The bottom surface of the bottom cover 51 abuts against the top of the mounting plate 2 when the bottom cover 51 is closed.

[0029] In this embodiment, a lower sensor 52 for monitoring the liquid level height in the measuring cylinder 5 and an upper sensor 53 for sensing the bottom of the storage bucket 3 are sequentially embedded at a position near the top of the inner wall of the measuring cylinder 5. A controller 14 and a storage battery 15 electrically connected to the motor are fixed to the top of the mounting frame 1. The controller 14 is electrically connected to the solenoid valve 31, the motor, the lower sensor 52, and the upper sensor 53. The lower sensor 52 monitors the liquid level height of the biogas slurry in the measuring cylinder 5 and transmits the liquid level height information to the controller 14 in the form of an electrical signal. When the real-time liquid level height approaches the preset measurement value, the controller 14 controls the feeding speed of the solenoid valve 31. When the real-time liquid level height reaches the preset measurement value, the solenoid valve 31 closes, and the motor starts to drive the rotating disk 4 to rotate, causing the empty measuring cylinder 5 to rotate. The bottom cover 51 in the measuring cylinder 5 at the discharge through hole 22 completely retracts into the measuring cylinder 5 after hitting the mounting plate 2. The upper sensor 53 senses the bottom of the storage bucket 3 and transmits the information to the controller 14 in the form of an electrical signal. A position sensing device such as a proximity switch can be used. When the upper sensor 53 monitors that the position of the measuring cylinder 5 corresponds to the bottom opening position of the storage bucket 3, the controller 14 controls the motor to stop running and the solenoid valve 31 to open. The biogas slurry in the storage bucket 3 enters the empty measuring cylinder 5 to complete the feeding. By repeating the above actions, the biogas slurry adding action of the empty measuring cylinder 5 and the biogas slurry fertilizing action in the field can be completed simultaneously.

[0030] To reduce the probability of a small amount of biogas slurry leaking from the gap between the bottom cover 51 and the measuring cylinder 5 and contaminating the mounting plate 2, a plurality of liquid outlet holes 23 are penetrated through the mounting plate 2. The plurality of liquid outlet holes 23 are evenly distributed about the axis of the rotating disk 4, and the orthographic projection of the plurality of liquid outlet holes 23 is located within the mounting frame 1. The top of the mounting plate 2 is smooth.

[0031] To enhance the sealing performance between the bottom cover 51 and the measuring cylinder 5, fillets 511 are provided at the intersections between the side wall of the bottom cover 51 and the top and bottom of the bottom cover 51. A sealing rubber ring (not shown in the figure) is fixedly sleeved on the side wall of the bottom cover 51. The setting of the fillets 511 enhances the smoothness of the bottom cover 51 during the rotation around its rotation axis. The setting of the sealing rubber ring enhances the sealing performance between the bottom cover 51 and the inner wall of the measuring cylinder 5 and reduces the probability of biogas slurry leakage in the measuring cylinder 5.

[0032] In this embodiment, there is a gap between the bottom of the rotating disk 4 and the top of the mounting plate 2. A scraper 41 that fits against the top of the mounting plate 2 is fixed to the bottom of the rotating disk 4. After the motor operates, it drives the rotating disk 4 to rotate, and the rotating disk 4 drives the scraper 41 to move synchronously, thereby cleaning a small amount of biogas slurry that leaks from the gap between the bottom cover 51 and the inner wall of the measuring cylinder 5 to the top of the mounting plate 2. A protective cover 7 is fixed to the bottom of the mounting plate 2 and covers the outside of the driving member 6. Moreover, heat dissipation holes 71 are provided at the bottom of the protective cover 7. The protective cover 7 plays a good protective role for the motor, avoiding the probability that biogas slurry drips onto the motor and damages the motor. The heat dissipation holes 71 are provided at the bottom of the protective cover 7, which facilitates the heat dissipation of the motor while reducing the probability that biogas slurry enters the inside of the protective cover 7 and causes the motor to rust.

[0033] The working principle of a field biogas slurry fertilizing device in this embodiment is as follows: The lower sensor 52 monitors the liquid level height of the biogas slurry in the measuring cylinder 5 and transmits the liquid level height information to the controller 14 in the form of an electrical signal. When the real-time liquid level height approaches the preset measurement value, the controller 14 controls the feeding speed of the solenoid valve 31. When the real-time liquid level height reaches the preset measurement value, the solenoid valve 31 closes, and the motor starts and drives the rotating disk 4 to rotate, causing the empty measuring cylinder 5 to rotate. The bottom cover 51 in the measuring cylinder 5 at the discharge through hole 22 completely retracts into the measuring cylinder 5 after hitting the mounting plate 2. The upper sensor 53 senses the bottom of the storage bucket 3 and transmits the information to the controller 14 in the form of an electrical signal. A position sensing device such as a proximity switch can be used. When the upper sensor 53 monitors that the position of the measuring cylinder 5 corresponds to the bottom opening position of the storage bucket 3, the controller 14 controls the motor to stop running and the solenoid valve 31 to open, and the biogas slurry in the storage bucket 3 enters the empty measuring cylinder 5 to complete the feeding. By repeating the above actions, the biogas slurry adding action for the empty measuring cylinder 5 and the biogas slurry fertilizing action in the field can be completed simultaneously.

[0034] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
