【Example】

 Examples will be described with reference to the drawings. Reference numeral 1 is a fertilizer feeding device in the fertilizer spreader for a tractor of the present invention. Reference numeral 2 is a fertilizer tank, which is composed of front and rear inclined walls 2A and left and right vertical walls 2B in a pyramidal shape, and a lower surface opening 2C is formed at the lower end. 2D is a cleaning port having a lid 2D1 which is provided on the side wall of the fertilizer tank 2 and which can be opened and closed. 3 is an appropriately sized delivery vehicle rotatably provided in the lower opening 2C of the fertilizer tank 2, and a fertilizer storage groove 3A having a substantially U-shaped cross section is provided on the outer periphery of the delivery vehicle 3. They are provided in parallel with each other in a direction orthogonal to the rotation direction of the delivery vehicle. The delivery vehicle 3 is made of a slippery plastic, and the upper portion 3B of the delivery vehicle 3 is arranged in a state of approaching the lower surface opening 2C of the fertilizer tank 2 from below. Therefore, when the feeding wheel is rotated, the fertilizer stored in the upwardly facing fertilizer storing grooves 3A is in a state in which the fertilizer storing grooves 3A face downward. , Will be discharged and scattered.

Reference numeral 4 denotes a lid-shaped adjustment plate provided in the fertilizer tank so as to cover the upwardly facing groove 3A for storing each fertilizer in the upper portion 3B of the feeding vehicle 3. That is, the adjusting plate 4 is formed in a reverse U shape with a gentle cross section so as to be along the upwardly facing grooves 3A for storing fertilizer in the upper portion 3B of the feeding wheel 3. In addition, the front and rear edges 4A of the adjusting plate 4 are slidably fitted to rails 2C1 attached inside the front and rear edges of the lower surface opening 2C of the fertilizer tank 2. Then, the adjusting plate 4 is inserted through the adjusting plate insertion port 2B1 opened in the one vertical wall 2B of the fertilizer tank 2, and can support the outer end of the adjusting plate to move in and out.

Reference numeral 5 denotes a stopper cylindrical wheel rotatably supported by bearings 2C3 continuously provided in front of the left and right portions of the lower surface opening 2C. The outer circumference of the core portion 5A is used for storing the above-mentioned fertilizers. A ridge 5B having an inverted V-shaped cross section, which has a width corresponding to the width of the groove 3A, is radially projected. The stopper cylindrical wheel is made of semi-hard rubber. In addition to the structure in which the protrusions 5B having an inverted V-shaped cross section are continuously provided, a groove may be formed so as to have a similar structure although not shown. In this case, the tip of the protrusion 5B is supported in contact with the bottom of the groove 3A for storing each fertilizer. Since the gear 3C on the side of the feeding wheel 3 and the gear 5C on the side of the stopper cylindrical wheel 5 mesh with each other, the stopper cylindrical wheel 5 rotates as the feeding wheel 3 rotates. Therefore, while the stopper cylindrical wheel 5 is rotating, the powdered manure or granular manure is dropped, and when the rotation of the stopper cylindrical wheel 5 is stopped, the fall of the powdered manure or granular manure is stopped.

Reference numeral 6 denotes a brush wheel rotatably supported by using brackets 2C2 that are continuously provided behind the left and right portions of the lower surface opening 2C. The brush bristles 6B each having a width corresponding to the width are radially planted. Naturally, the tips of the brush bristles 6B come into contact with the bottoms of the fertilizer storing grooves 3A, rotate with the rotation of the feeding wheel 3, and try to adhere to the bottoms of the fertilizer storing grooves 3A. It will scrape away powdered or granular fertilizer. Reference numeral 7 denotes a driving wheel, which is configured to interlock with the delivery vehicle 3. FIG. 1 shows a case where an appropriate number of fertilizer sowing machines are arranged on the frame F. In this case, the adjusting plates 4 are connected by the connecting rod 8 and are operated simultaneously. The amount of fed fertilizer is increased / decreased by operating the adjusting plate 4. Reference numeral 9 is a well-known agitator horizontally laid in the fertilizer tank 2. 9A is a gear on the agitator side, and is connected to a gear 3D on the feeding wheel 3 side by a chain 9B.

The operation will be described together with the effect.

[0010]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. Since a plurality of grooves 3A for storing fertilizer are provided on the outer circumference of an appropriately sized delivery vehicle provided in the lower opening of the fertilizer tank, and a lid-shaped adjustment plate is installed along the upper surface of the fertilizer tank, the moving wheel is If it rotates, the interlocked delivery car turns in the direction of the arrow. At the same time, the fertilizer contained in the fertilizer storage groove 3A goes out of the fertilizer tank and falls. By moving the adjustment plate in and out of the fertilizer tank, the amount of fertilizer delivered can be adjusted. In other words, if you move the fertilizer tank to the left (arrow C) to the left, you will cover the fertilizer storage groove 3A located in the fertilizer tank. Becomes

As a result, the amount of fertilizer delivered is uniform even if it is considerably inclined. It is configured so that the fertilizer powder does not adhere to the groove portion 3A for storing the fertilizer. That is, since it is made of special plastic molding with good slipperiness, powdered fertilizer and granular fertilizer are less likely to adhere to the groove portion 3A for storing the fertilizer, and reliable fertilizer spreading can be performed. In this case, even if powdered fertilizer or granular fertilizer tries to adhere to the groove 3A for storing the fertilizer, the brush wheel rotates with the rotation of the feeding wheel 3, and the tip of the brush bristles of the brush wheel always stays. Since it comes into contact with the bottom of each fertilizer storage groove 3A, it is possible to scrape off the powdered or granular fertilizer that is about to adhere to the bottom of the fertilizer storage groove 3A.
