[0005]

[Action]

 In the fertilizer spreader of the present invention, when compost is thrown in from above the compost tank, it falls below the compost tank and reaches the stirring device. Then, compost is finely crushed by many stirring rods attached to the rotating rotating shaft. The compost comminuted falls from the stir bar and reaches the horizontal conveyor. The compost is gradually moved by the horizontal conveyor, reaches the mixing chamber, and falls from the horizontal conveyor. Further, a fertilizer container is provided above the mixing chamber, and another fertilizer is sent to the mixing chamber. The compost and fertilizer that has reached the mixing chamber reach the downstream of the wind path through a discharge pipe from the lower part of the mixing chamber. In the wind path, high-speed airflow is generated by a high-pressure fan installed upstream. The compost and fertilizer that has reached the airway is blown downstream by the high-pressure airflow in the airway and gushes from the airway exit. In addition, since a discharge amount adjustment valve is provided in the discharge pipe connecting the lower part of the mixing chamber and the downstream of the wind path, the amount of compost and fertilizer ejected is controlled by adjusting the amount of compost and fertilizer that falls into the wind path. A system that sends high-pressure air from the wind path to the inside of the mixing chamber prevents compost from sticking to the inside of the mixing chamber even when the compost has a lot of moisture, and increases the force of the high-pressure air to move the compost from the feed pipe to the wind path. Prevent reflux. Pipes that feed high-pressure air from the airway to multiple fertilizer containers prevent fertilizer from sticking to the inside of the fertilizer container even when the fertilizer has a lot of moisture, and the high-pressure air mixes the compost from the lower tube of the fertilizer container. Strengthen the power to send indoors and prevent backflow. At the outlet of the airway, a nozzle that spreads laterally as it goes downstream is gradually increased by the high-speed airflow generated by the high-pressure fan installed upstream of the airway, and the jet flow follows the shape of the nozzle. As it forms, the flow coming out of the spout further spreads in the horizontal direction, so that compost is spread over a wide area in the horizontal direction. If a flexible hose is installed at the exit of the airway, it can be reached by a flexible hose even in places where the compost spreader of the present invention cannot be reached. If the discharge pipe is inserted obliquely into the wind path toward the downstream, the air flow hits the inside of the discharge pipe and changes direction to prevent the fertilizer from flowing back. If the amount of the discharge pipe entering the air passage from the lower part of the mixing chamber is set to 1/2 to 2/3 of the height of the air passage from the upper end of the air passage, the tip of the feed pipe should be connected to the fastest part of the air passage. Positioning will blow off the compost with a faster air flow. If the tip of the screw conveyor is located in the mixing chamber, the compost sent from the compost tank by screw conveyor and the fertilizer sent from the fertilizer tank are mixed by rotating the screw conveyor in the mixing chamber. To mix evenly.

As shown in FIGS. 1 and 2, the compost sprayer according to the first embodiment is provided with a tapered compost tank 2 having two lateral sides narrowed downward, and a large number of stirring rods 3a inside the compost tank 2. A stirrer 3 is provided radially attached to the rotating shaft, and a screw conveyor 4 is provided below the stirrer 3. In the first embodiment, a screw conveyor is used as the horizontal feed conveyor. As shown in FIG. 3, one end serving as a destination of the screw conveyor 4 projects from the compost tank 2 and is positioned in a mixing chamber 20 provided outside the compost tank. The stirrer 3 and the screw conveyor 4 are driven by a motor 13 by engagement of a belt as shown in FIG. The motor 13 uses a battery 14 as a power source. The left and right side surfaces of the mixing chamber 20 have a tapered shape in which the lower part is narrowed. Two fertilizer containers 5 are provided above the mixing chamber 20. The lower part of the fertilizer container 5 is also partially tapered. At the lower part of the fertilizer container 5, adjustment valves 21 for adjusting the amount of fertilizer sent to the mixing chamber 20 are provided. Pipes 22 are provided below the regulating valves so as to be connected to the mixing chamber. A wind path 6 is provided below the compost tank 2 as shown in FIGS. A high-pressure fan 7 is provided upstream of the wind path 6. From the lower part of the mixing chamber 20, a discharge pipe 23 to the air path 6 is obliquely protruded downstream into the air path 6, the discharge pipe 23 is provided with a discharge amount adjusting valve 9, and the discharge pipe 23 is provided from the mixing chamber. Branch pipes 8 and 10 for feeding wind pressure to the inside of the mixing chamber 20 and the two fertilizer containers 5 from the upstream of the wind path position from which the fertilizer container 5 is protruded. An adjustment valve 24 for adjusting the wind pressure is provided, and a nozzle 11 is provided which spreads laterally toward the downstream of the outlet of the wind path 6. A wire net 19 is provided above the stirring device 3. In order to use the compost disperser 1 of the first embodiment to mix and disperse the compost and two types of fertilizer, the compost 15 is charged from above the compost tank 2 as shown in FIG. When the compost 15 is introduced, the wire mesh 19 is provided above the stirring device 3, so that the hand is not accidentally touched to the stirring device, so that the compost 15 can be safely and safely poured into the compost tank 2. In addition, two types of fertilizers are placed in two fertilizer containers. When the input compost 15 falls and reaches the stirring device 3, a large number of stirring rods 3a attached to a rotating shaft rotated by a motor 13 as shown in FIG. Thus, the compost 15 is stirred while being finely crushed. The comminuted compost 15 falls downward, reaches the screw conveyor 4, and sends the compost 15 to the mixing chamber by the rotation of the spiral blades of the screw conveyor 4. A high-speed fan 7 generates a high-speed air flow in the wind path 6. Wind pressure is applied to the two fertilizer containers 5 by a branch pipe 10 provided on the upstream side of the wind path 6 from the discharge pipe 23. Further, the wind pressure to the fertilizer container 5 can be appropriately adjusted by the wind pressure adjusting valve 24. The fertilizer is sent from the fertilizer container 5 to the mixing chamber through the pipe 22 by the pressurization by the wind pressure and the weight of the fertilizer itself. Further, the amount of fertilizer sent from each fertilizer container 5 to the mixing chamber 20 is adjusted by an adjusting valve 21 provided at the upper part of the pipe 22. Even if the fertilizer has a lot of water and tends to stick to the fertilizer container, the wind pressure prevents the fertilizer container from sticking to the fertilizer container. It also prevents clogging and simplifies post work. The finely composted compost and the two types of fertilizer sent into the mixing chamber 20 are stirred by the screw conveyor 4 projecting into the mixing chamber 20, and are branched from the branch pipe 8 from the air passage 6 into the mixing chamber 20. As air is blown out, the mixture is further stirred and uniformly mixed. The compost and the two types of fertilizer uniformly mixed in the mixing chamber 20 are sent to the wind path 6 through the discharge pipe 23 by the weight and the wind pressure by the branch pipe 8. Further, the discharge pipe 23 is provided with a discharge amount adjusting valve 9 to appropriately adjust the amount of spouting the mixed compost and the two types of fertilizer. The discharge pipe 23 protrudes into the wind path 6, and when the airflow flowing through the wind path directly hits the inside of the discharge pipe, a backflow of air to the mixing chamber occurs, and the mixed compost and fertilizer also flow back. In order to avoid such a situation, the discharge pipe 23 is attached obliquely toward the downstream side. Therefore, such a backflow can be prevented and more efficient and uniform spraying can be achieved. The mixture of two types of fertilizer and the compost dropped from the discharge pipe 23 or from the discharge pipe 23 is blown downstream by the airflow flowing through the wind path 6 at high speed. The mixture of the blown compost and the two kinds of fertilizers is sprayed to the outside by the nozzle 11 which is provided at the downstream end of the wind path 6 so as to spread horizontally by the nozzle 11 which becomes wider toward the downstream. I do. As shown in FIG. 4, this compost spreader is mounted on a moving vehicle 18 often used by farmers and the like, and if the compost 15 and the two types of fertilizer 16 are mixed and moved while being spread, a large tractor cannot be entered. Even in places, it is easy to spread a wide area in a short time, it is very easy to work, it is easy to move, and the fertilizer can be spread evenly and evenly throughout the place. FIG. 5 is an explanatory diagram showing a state in which another example of the compost spreader of the first embodiment is used. In the figure, reference numerals are the same as those in the first embodiment. In another example of the first embodiment shown in FIG. 5, the nozzle 11 attached to the outlet of the air passage 6 is replaced with a flexible hose 12. The nozzle 11 attached to the outlet of the wind path 6 is flexible to spray in places where fruit trees are densely packed or in a house where a mobile vehicle carrying the compost spreader 1 cannot enter. It is sufficient to replace the hose 12 with the hose 12 to reach the place where the hose is to be sprayed and spray the hose. In this way, it can be sprayed in places where fruit trees are dense, such as in orchards. In addition, it can be used even when it is desired to apply fertilizer only around the plant, and fertilizer can be applied effectively. Second Embodiment (see FIGS. 6 and 7) FIG. 6 is an explanatory diagram of a compost spreader according to a second embodiment. FIG. 7 is an explanatory diagram illustrating a state in which the compost spreader according to the second embodiment is used. In Example 2 shown in FIGS. 6 and 7, a large number of stirring rods are provided inside a compost tank in which all of the two sides or a part of the lower side are tapered so that the compost gathers at the lower center when the compost is injected from above. A stirrer attached radially to the rotating shaft is provided, a horizontal feed conveyor is provided below the stirrer inside the compost tank, a mixing chamber for receiving compost conveyed by the horizontal feed conveyor is provided, and a plurality of mixing chambers are provided above the mixing chamber. A fertilizer container was provided, a pipe with an adjusting valve for sending fertilizer from the fertilizer container to the mixing chamber was provided, an air path for sending high-pressure air generated by a high-pressure fan was provided, and a discharge amount adjusting valve from the mixing chamber was provided. The discharge pipe protrudes into the air duct, and a branch pipe that connects the inside of the air duct and the inside of the mixing chamber with a plurality of fertilizer containers is provided in the air duct at a position upstream of the wind path where the discharge pipe of the mixing chamber protrudes. Into the water diagonally toward the downstream The amount of entry of the discharge pipe from the lower part of the mixing chamber into the inner surface of the air passage is set to 1/2 to 2/3 of the height of the air passage from the upper end of the inner surface of the air passage. This is an example of a compost spreader that mixes and blows out from an airway outlet. In the figure, 25 is a belt type conveyor. In Example 2 shown in FIG. 6, a shorter stirring rod is provided on the stirring rod 3a of the stirring device 3, and the compost is pulverized finer and stirred. Further, a belt-type conveyor 25 is used as a lateral feed conveyor. No nozzle or hose is provided at the airway exit. The amount of protrusion of the discharge pipe 23 from the lower portion of the mixing chamber 20 to the downstream of the air path 6 is set to ２〜 to ３ of the height of the air path from the upper end of the air path 6. When the compost containing the fertilizer is sent from the tip of the discharge pipe 23, the compost containing the fertilizer is blown downstream with a stronger force because the compost containing the fertilizer becomes a high-speed flow portion in the wind path. Therefore, the compost is sprayed efficiently. If the compost spreader according to the second embodiment is used by placing it on a truck or the like, the work can be simplified and the work time can be extremely shortened even when the places where the compost is desired to be spread are extremely scattered. Further, in both of the first and second embodiments, it can be used to spray only compost or only fertilizer. If it is not necessary to mix fertilizer with compost, there is no need to provide a fertilizer container and mixing room.

[0008]

[Effect of the invention]

 According to the present invention, the work can be performed very easily, the working time can be shortened, the fertilization can be spread over the entire area, the fertilization can be effectively performed, and even if the fruit trees are densely spread, the hand-held mobile vehicle can be used. A fertilizer spreader that can be used and used can be provided. The provision of pipes for sending wind pressure from the air duct to the fertilizer containers prevents the fertilizer from sticking to the inside of the fertilizer container, thereby preventing clogging and simplifying subsequent work. In addition, clogging is also prevented by increasing the power to send fertilizer by wind pressure. A nozzle provided with a nozzle that spreads laterally at the outlet of the wind path gradually as it goes downstream can spread the compost over a wide area in the horizontal direction, further shorten the working time, and further spread the fertilization throughout. A hose with a flexible hose at the exit of the airway can be sprayed in places where plants are dense and the compost spreader of the present invention cannot enter. A pipe with a discharge pipe from the lower part of the mixing chamber obliquely protruding downstream into the wind path prevents the backflow of fertilizer and makes it possible to spray compost more efficiently and uniformly. When the amount of rush of the discharge pipe from the lower part of the mixing chamber to the downstream of the air path is set to 1/2 to 1/3 of the height in the air path from the upper end of the air path, the compost is sprayed efficiently. The screw conveyor with the tip of the destination located in the mixing chamber can mix the compost and fertilizer evenly and make more effective fertilization as a whole.
