Robert Jandl company in Rothmühl, Czechoslovak Republic.

Fertilizer spreader in which the width of the spreading slot is changed periodically the lower part of one box wall is movable relative to the other box wall.

Patented in the German Empire on June 14, 1925.

According to the Union Treaty of June 2, 1911, priority is due to this application of the application in the Czechoslovak Republic of December 16, 1924.

The invention relates to a fertilizer spreader of the type in which the purpose periodic change in the width of the litter slot the lower part of one box wall is movable relative to the other box wall. The essence of the invention lies

in that the up and down movement of the movable lower box wall part is essentially takes place in the plane of the box wall part in such a way that the lower end face of the movable Box wall part when going down the box part in the lower part

of the box located fertilizer of a distribution device supplies, while when the box wall part goes up, the resulting empty space is again filled with fertilizer-S fills. Such a design of the fertilizer spreader is a particularly good and uniform supply of fertilizer to the distribution device and a dement- ' An appropriate distribution of the fertilizer achieved when ίο spreading.

In order to give the movable box wall part the marked up and down movement, it can be rotatably mounted for example by means of swing arms about a pin arranged on the opposite box wall be.

In the drawing, 1 denotes the manure box. The manure box is with a vibrating lower part 3 is provided, which by means of two lateral rocker bars 4 at the pin 5 is rotatably mounted. The vibrating lower part 3 is made up of gears 6, 7, connecting rod 8, link 9, lever 10 and connecting rod 11 by means of the lateral Rocking iron 4 in direction of arrow 23 set in vibration. The size of this Vibrations is determined by the respective position of the connecting rod 8 in the link 9, whereby the forced setting of the amount of fertilizer to be spread is achieved. Because of the swaying movement of the lower part 3 arise during the upward movement of the latter empty spaces in the lower part of the manure box, in which the Fertilizer by itself or with the help of the adjustable slide that goes back and forth 13 falls into it. With the downward movement of the lower part 3, the fertilizer is then with the help the front edge 12 of the vibrating lower part 3 by the slide 13 and The slot formed in the base plate 2 in the direction of the arrow 33 onto the storage area 32 promoted.

The design of the device is such that the front edge 12 of the vibrating part 3 always vibrates up to the position indicated by a in Fig. 3, despite the different oscillation amplitudes χ. This is achieved in that the link 9 is curved at the mentioned end position α of the end edge 12 with a radius around the axis of the crank drive of the connecting rod 8 as the point of curvature.

The reciprocating slide 13 is formed by bevel gears 19, 20 and connecting rod 21 moved back and forth in the direction 26. The guide of the slide 13 is made by flat iron 14 and guide piston 15 made.

At the ends of the flat iron 14 slotted holder 17 are attached, in which the Slide 13 is held by pins 18 so that it is in the direction of the Arrow 27 can be raised. The flat iron 14 and slider 13 are through Set screws 16 mutually clamped "and" therefore form a at work Whole.

The fertilizer is spread from the storage area 23 by means of a distributor 28.

A fertilizer spreader according to the invention has over other fertilizer spreaders the advantage that even hygroscopic fertilizers or mixtures in which such Fertilizers are contained, can be spread exactly, and this is with the achieved very simple device described above.

Claims (3)

Patent Claims: i. Fertilizer spreader in which the width of the spreading slot is changed periodically the lower part of one box wall is movable with respect to the other box wall, characterized in that the up and down movement of the movable lower box wall part (3) essentially takes place in the plane of the box wall part (3) in such a way that the lower end face of the movable box wall part (3) when going down the box part (3) the one located in the lower part of the box Feeds fertilizer to a distribution device, while the upward movement of the box wall part (3) removes the refills empty space with fertilizer. 2. Fertilizer spreader according to claim 1, characterized in that the lower end position of the vibrating manure box part (3) always remains approximately the same despite different settings of the Vibration amplitudes by adding in the drive gear for the vibrating manure box part (3) a gate (9) is provided, which in the lower end position of the vibrating manure box part (3) the center of the crank drive of a connecting rod (8) is curved, one end of which engages the link (9) and in this can be determined in different positions. 3. fertilizer spreader according to claim 1 and 2, characterized in that the Movements of two box lower parts cross each other.
