Aiming at the problems of mismatch between supply and demand of nutrients in existing farmland and no way out for livestock and poultry manure, the present invention provides a self-propelled liquid fertilizer quantitative spraying device, which has the advantages of low operating pressure, wide spraying range and power consumption. It has the advantages of low quantity and accurate quantification of liquid fertilizer.

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

As shown in Figures 1-2, the present invention provides a self-propelled liquid fertilizer quantitative spraying device, which is composed of a claw rotary joint 2, a transmission device, a forward device and a chassis.

The spraying arm 1 and the horn rotary joint 2 play the role of converting the pressure of the livestock and poultry manure sewage solution into a rotating force, and are composed of an adjustable spray head, a spraying arm 1, a flywheel 4 and a water inlet device. After being pressurized by the pressurizing pump, the livestock and poultry manure is connected by the pipeline to the water inlet device of the horn rotary joint 2 to realize the water inlet function of the device. The end of the spraying arm 1 is connected with a spray head. By adjusting the nozzle of the spray head to a suitable angle (the nozzle is at a certain angle with the horizontal direction), the liquid fertilizer is sprayed from the nozzle, so that the horn rotary joint 2 is driven by the water jet reaction force. . A flywheel 4 is connected to the middle of the claw rotary joint 2. The flywheel 4 rotates synchronously with the claw rotary joint 2. The flywheel 4 is designed to have a special shape with a concave-convex structure. When rotated to the protruding position, the rocker arm 5 in the transmission Moving forward, when rotated to the recessed position, the rocker arm 5 in the transmission moves backward.

The horn rotary joint 2 is divided into a fixed part and a rotating part, and the fixed part is connected with the frame 12 .

The transmission device plays the role of transmitting the energy output of the claw rotary joint 2 to the forward device. composition. The rocker arm 5 is continuously moved back and forth under the drive of the horn rotating nozzle 2. When the rocker arm 5 moves forward, it pushes the pawl 6 to move forward. backward movement under the traction. At the same time, in order to limit the position of the pawl 6, a tension spring 7 is used to connect the pawl 6 and the rocker arm 5. The rocker arm base 11 is used to fix various components in the transmission.

In particular, the upper end of the rocker arm 5 is provided with a roller 3 axis, and the roller 3 is fixed on the roller 3 axis. The roller 3 works together with the flywheel 4 of the claw rotary joint 2 to realize the function of converting the rotation of the claw rotary joint 2 into the forward and backward movement of the rocker arm 5 .

The forward device plays the role of pulling the self-propelled liquid fertilizer quantitative spray device to move forward, and is composed of a ratchet wheel 10, a steel cable drum 9, a non-return claw and a steel cable. In actual use, the steel cable is connected to the remote fixture, the ratchet 10 rotates under the push of the pawl 6 in the transmission device, and drives the cable drum 9 to rotate, the length of the steel cable is reduced, and the steel cable pulls the self-propelled liquid fertilizer The quantitative spraying device keeps advancing. Since the device has a certain self-weight and has a large resistance to movement in the farmland, the wire rope is in a tight state. 10 The lower part is provided with a non-return claw.

The chassis plays the role of fixing the components of the self-propelled liquid fertilizer quantitative spraying device and moving forward, and is composed of a frame 12 and front and rear wheels. In particular, in order to ensure the stable center of gravity of the self-propelled liquid fertilizer quantitative spraying device, the rotating part of the horn rotary joint 2 is connected to the middle of the frame 12, and the transmission device and the forwarding device are respectively arranged according to the horn rotary joint 2 at appropriate positions. In the chassis, the front wheels are 12-inch pneumatic tires 13, and the rear wheels are 4-inch tires 14.

The spraying device of the invention has the advantages of wide spraying range, accurate quantitative liquid fertilizer, low operating pressure and high energy efficiency ratio. In addition, by changing the length of the spraying arm 1 on the horn rotary joint 2, the angle of the spraying head and the outlet pressure of the pressurizing pump, the dynamic adjustment of the spraying amount and the spraying area can be realized.

After being pressurized by the pressurizing pump, the livestock and poultry manure is transported to the water inlet device of the horn rotary joint 2 by the pipeline. The flow and head of the booster pump can be selected according to the needs. The manure moves upward along the pipeline under the action of pressure, and is sprayed by the adjustable nozzle at the end of the spray pipe. In order to ensure uniform spraying within the coverage area of the spray pipe, the lengths of the two spray pipes are The extension length is 3500mm, the height of the end of the spraying pipe is 1300mm from the ground, and the spray coverage area is covered by one rotation.

The claw rotary joint 2 rotates to drive the steel cable drum 9 in the advancing device to rotate, thereby pulling the self-propelled liquid fertilizer quantitative spraying device forward, and has a certain forward speed; when the self-propelled liquid fertilizer quantitative spraying device gradually advances In the process, the spraying of liquid fertilizer along the field is realized.

Example 1

The livestock and poultry manure used in this embodiment is the liquid in the dry and wet separation of the pig farm, which is stored in the pool after being processed by the sewage treatment process. The type of booster pump adopts a submersible sewage pump, which is set in the pool and transported to the horn rotary joint 2 by the pipeline. The application farmland is the farmland of the farmers around the pig farm, and the implementation season is before the winter wheat planting, which is sprayed by the self-propelled liquid fertilizer quantitative spraying system.

In the present invention, specific examples are used to illustrate the principles and implementations of the present invention, and the descriptions of the above embodiments are only used to help understand the method and the core idea of the present invention; There will be changes in the specific implementation manner and application scope of the idea of the invention. In conclusion, the contents of this specification should not be construed as limiting the present invention.
