[0032] This embodiment provides a fertilizer spreading machine, see Figure 1-Figure 5As shown, it includes a main body 1, which is composed of an air pipe 2 and a branch pipe 3. The air pipe 2 is connected to the branch pipe 3, and air outlets are arranged at both ends of the branch pipe 3. An air inlet 21 is opened on the outer wall of the air pipe 2, a fan 22 is installed in the air pipe 2, and a storage cavity 23 is installed on the side of the air pipe 2. The branch pipe 3 is connected to the storage cavity 23 through a feeding pipe 4, and one end of the feeding pipe 4 extends into the storage cavity 23. A filling hole is opened on the side wall of the storage cavity 23, and a cover plate 231 is arranged at the filling hole. A vent hole 232 is opened on the upper end surface of the storage cavity 23.

[0033] In the above embodiment, the fertilizer spreader includes a main body 1, which is composed of an air pipe 2 and a branch pipe 3 connected to each other. A fan 22 is installed in the air pipe 2. The fan 22 is operated to suck the air outside the air pipe 2 through the air inlet 21 opened on the outer wall of the air pipe 2 and blow it into the branch pipe 3 to generate a flowing airflow in the branch pipe 3. According to Bernoulli's principle, when the gas flows at a high speed in a pipeline or other fluid medium, its kinetic energy will increase, while the pressure will decrease, that is, the airflow flows in the branch pipe 3 to generate a negative pressure in the branch pipe 3. A storage cavity 23 is installed on the side of the air pipe 2. The branch pipe 3 is connected to the storage cavity 23 through a delivery pipe 4. One end of the delivery pipe 4 extends into the fertilizer in the storage cavity 23. The negative pressure in the branch pipe 3 causes the delivery pipe 4 to generate suction to The fertilizer in the storage chamber 23 is sucked into the branch pipe 3. A filling hole is provided on the side wall of the storage chamber 23. A cover plate 231 is provided at the filling hole. Fertilizer can be added into the storage chamber 23 by opening the cover plate 231. An air vent 232 is provided on the upper end surface of the storage chamber 23. The air vent 232 is used for allowing external air to enter the storage chamber 23 through the air vent 232 when the delivery pipe 4 sucks the fertilizer in the storage chamber 23 into the branch pipe 3, thereby balancing the air pressure in the storage chamber 23, avoiding the delivery pipe 4 from sucking material in the storage chamber 23, causing the air pressure in the storage chamber 23 to be too low, thereby causing the pressure difference between the branch pipe 3 and the storage chamber 23 to decrease, thereby reducing the suction force of the delivery pipe 4, causing the delivery pipe 4 to suck material poorly, which is beneficial to improving the smoothness of the delivery pipe 4 sucking fertilizer. The airflow has kinetic energy when circulating in the branch pipe 3. When the airflow in the branch pipe 3 contacts the fertilizer, it will generate thrust on the fertilizer in the branch pipe 3, so that the fertilizer sucked into the branch pipe 3 is ejected through the outlet along with the airflow in the branch pipe 3, so as to realize the spreading of the fertilizer. In the spreading process, direct contact between people and fertilizer is avoided, the labor intensity of manual fertilizer spreading is reduced, and it is beneficial to improve the efficiency of fertilizer spreading.

[0034] In one embodiment of the present application, see Figure 3 As shown, a motor 233 is installed at the bottom of the storage chamber 23, and the motor 233 is in transmission connection with a transmission rod 234, and the transmission rod 234 extends into the feed pipe 4, and a spiral blade 2341 is connected to the outer periphery of the transmission rod 234.

[0035] In the above embodiment, when encountering fertilizers with larger particles, the feed pipe 4 may have insufficient suction force, resulting in poor fertilizer distribution. The motor 233 installed at the bottom of the storage chamber 23 drives the transmission rod 234 to rotate. The outer periphery of the transmission rod 234 is connected with a spiral blade 2341. The transmission rod 234 drives the spiral blade 2341 to rotate, and the fertilizer in the storage chamber 23 is pushed into the branch pipe 3 through the feed pipe 4, and then the fertilizer is blown out of the branch pipe 3 through the airflow in the branch pipe 3 for fertilizer distribution, which is beneficial to improve the smoothness of large-particle fertilizer distribution.

[0036] In one embodiment of the present application, refer to Figure 5 As shown, a bracket assembly 5 is installed on one side of the body 1.

[0037] In the above embodiment, the bracket assembly 5 is used to connect and hang the main body 1 on the agricultural machine to perform fertilizer spreading operations, which is beneficial to improving the portability of the fertilizer spreader.

[0038] In one embodiment of the present application, see Figure 5 As shown, the support assembly 5 includes a cross bar 51 and a vertical bar 52 , a plurality of hanging ears 511 are installed on the cross bar 51 , and a perforated plate 521 is installed on the vertical bar 52 .

[0039] In the above embodiment, the bracket assembly 5 includes a cross bar 51 and a vertical bar 52, and the main body 1 can be connected and reinforced by the cross bar 51 and the vertical bar 52, which is beneficial to increase the stability of the fertilizer spreader. In addition, the multiple ears 511 installed on the cross bar 51 and the orifice plate 521 installed on the vertical bar 52 can increase the connection points between the bracket assembly 5 and the agricultural machinery, which is beneficial to improve the adaptability of the fertilizer spreader installation.

[0040] In one embodiment of the present application, see Figure 1 As shown, a protective net 211 is installed at the air inlet 21 .

[0041] In the above embodiment, a protective net 211 is installed at the air inlet 21 to filter the air entering the air inlet 21. When the fertilizer spreader is spreading fertilizer on the farmland, it blocks dust, leaves, insects and other debris from entering the air pipe 2 and causing the fan 22 to be blocked and shut down, which is beneficial to improving the stability of the operation of the fertilizer spreader.

[0042] In one embodiment of the present application, see Figure 4 As shown, a splitter plate 6 is provided above the connection between the air pipe 2 and the branch pipe 3 .

[0043] In the above embodiment, the diverter plate 6 can be used to divert the airflow generated by the fan 22 at the connection between the air pipe 2 and the branch pipe 3, and guide the airflow to flow to the two ends of the branch pipe 3 respectively, so that the gas flows more evenly and stably in the branch pipe 3, reducing the noise and vibration generated during the gas flow, preventing the airflow from colliding and disturbing in the branch pipe 3, and reducing the kinetic energy loss of the airflow.

[0044] In one embodiment of the present application, see Figure 4 As shown, a first butterfly valve 71 is installed at one end of the branch pipe 3 , and a second butterfly valve 72 is installed at the other end of the branch pipe 3 .

[0045] In the above embodiment, during the fertilizer spreading process, it may be necessary to spread fertilizer on one side. At this time, the fertilizer spreading machine can be implemented by closing the first butterfly valve 71 or the second butterfly valve 72 at the end of the branch pipe 3, which is beneficial to improve the flexibility of fertilizer spreading.

[0046] In the actual use process of the present application: the fan 22 is operated to suck the external air of the air pipe 2 through the air inlet 21 opened on the outer wall of the air pipe 2 and blow it into the branch pipe 3 to generate a flowing airflow in the branch pipe 3. A storage chamber 23 is installed on the side of the air pipe 2. The branch pipe 3 is connected with the storage chamber 23 through the delivery pipe 4. One end of the delivery pipe 4 extends into the fertilizer in the storage chamber 23. The negative pressure in the branch pipe 3 causes the delivery pipe 4 to generate suction to suck the fertilizer in the storage chamber 23 into the branch pipe 3. A filling hole is opened on the side wall of the storage chamber 23. A cover plate 231 is provided at the filling hole. When the filling hole is opened, The cover plate 231 can add fertilizer into the storage chamber 23. An air vent 232 is provided on the upper end surface of the storage chamber 23. The air vent 232 is used for external air to enter the storage chamber 23 through the air vent 232 when the conveying pipe 4 sucks the fertilizer in the storage chamber 23 into the branch pipe 3, thereby balancing the air pressure in the storage chamber 23. The airflow has kinetic energy when flowing through the branch pipe 3. When the airflow in the branch pipe 3 contacts the fertilizer, it will generate thrust on the fertilizer in the branch pipe 3, thereby causing the fertilizer sucked into the branch pipe 3 to follow the airflow in the branch pipe 3 and be ejected through the outlet to achieve the spreading of the fertilizer.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it.
