  In the form of spraying powder and granular fertilizers with a fertilizer spreader that spreads manure and manure, the fertilizer that diffuses and discharges forward from the spray port is easily blown away by the wind, and it is difficult to spread to the target position. It tends to become unsanitary due to splashing.

According to the first aspect of the present invention, a sheet support frame 3 is provided on the upper front side of the spraying port 2 for spreading the fertilizer by the rotation of the diffusion blades 1. It is set as the structure of the spreading | covering cover of the fertilizer spreader characterized by supporting the seat cover 4 which covers a part. In the fertilizer spreader, the fertilizer fed from the hopper is diffused and discharged forward through the spout 2 by the rotation of the diffusion blades 1 and scattered forward and left and right over a wide width. At this time, when the sprayed fertilizer is easily affected by wind, the seat cover 4 is attached to the upper front side of the spraying port 2. A seat support frame 3 is attached to the front upper part of the spraying port 2, a seat cover 4 is attached to the sheet support frame 3, and the front upper part and the outer periphery of the spraying port 2 are covered over the spraying region. The fertilizer discharged forward from the spraying port 2 is guided to the inner area of the seat cover 4 and sprayed into the predetermined spraying area. For example, even if a strong wind blows, it is difficult for the wind to pass through the seat cover 4, and it is less likely to directly hit the spraying port 2, thereby preventing fertilizer from being scattered on the upper side and the outer periphery of the seat cover 4.
The invention according to claim 2 is characterized in that the sheet support frame 3 is provided in the upper part of the spray port 2 so as to be foldable and storable, and the spray cover of the fertilizer spreader according to claim 1 is characterized. It is. When attaching the seat cover 4, the seat support frame 3 housed in the upper part of the spout 2 is opened and positioned on the upper front side of the spout 2, and the seat cover 4 is attached to the seat support 3. Cover the upper front part of the spout 2. When the seat cover 4 is not required, the sheet support frame 3 is folded and stored and held above the spout 2.

Prevent ventilation and direct wind contact to the two parts of the spraying port, reduce the scattering of the spread fertilizer upwards or outwards, and perform precise fertilizer spraying, and also perform hygienic spraying work Can do.
Since the seat support frame 3 is housed and supported on the upper side of the spout 2 in the second aspect of the invention, the seat cover 4 can be taken out easily and stored when the seat cover 4 is not used. It can be made into a form which does not get in the way even in the storage state.

  Based on the drawings, the general structure of the fertilizer spreader is a spreader 13 comprising a hopper 10 for storing fertilizer, feeding rotors 11 and 12, diffusion blades 1, and the like in a front upper portion of a chassis 9 having a pair of left and right crawlers 8. The transmission mechanism 14, the engine 15, the handle 16, and the like are provided at the rear, and the fertilizer is diffused and spread forward from the spray port 2 by the rotation of the diffusion blade 1 while traveling forward by the gripping operation of the handle 16. . The hopper 10 has 17 left and right side walls, 18 front walls, and 19 rear walls. These front walls 18 can be opened horizontally by turning to the front side, so that fertilizer can be easily supplied from the front side. Further, the rear wall 19 has a handle 20 and can be swung back and forth to smoothly feed the fertilizer. In this hopper 17, the feeding rotor 11 is mounted on the bottom outlet 21, and the upper feeding rotor 12 is mounted on the shaft 23 on the side of the rear wall 19, which has a gentle slope.

  The bottom feeding outlet 21 of the hopper 10 is formed wide across the hopper width between the left and right side walls 17 and allows the fertilizer fed by the feeding rotor 11 to flow down into the diffusion chamber 26 where the lower diffusion blade 1 rotates. Can do. The outlet 21 is provided with a shutter 27 that opens and closes by moving back and forth, and is opened and closed by an operating lever 28 of the handle 16 through an interlocking rod 29 and a link mechanism 30. In the diffusion chamber 26, a pair of right and left diffusion blades 1 are rotationally interlocked around a vertical diffusion axis 31. A spray port 2 is formed on the front side of the diffusion chamber 26. Due to the rotation of the diffusion blade 1, the fertilizer fed from the feeding port 21 is received and discharged forward from the spraying port 2 and sprayed. A branch plate 32 for guiding the fertilizer to the left and right sides is provided at the center of the spray port 2, and a side guide plate 33 is provided in front of both sides of the spray port 2. Rubber mats 34 and 35 are laid on the inner surfaces of the front wall 18 and the rear wall 19 of the hopper 10 to smoothly feed out the fertilizer.

  A seat cover 4 is provided in front of the spout 2. Since the seat cover 4 is a light and thin sheet such as a synthetic resin sheet, the seat cover 4 is supported or suspended by a sheet support frame 3 made of a thin material. The sheet support frame 3 is made of a wire material and is light in weight, and is formed widely over the spreading width. Further, it is folded and stored along the front wall 18 of the hopper 10.
