Stable manure removal device with rope manure scraper

The invention relates to a stable manure removal system device with a manure scraper, which is pulled by a cable pull by means of a cable winch.

In the previously known stall demisters of this type, the one driven by an electric motor The winch is set in motion by a strong, jerky pulling of the pulling rope by hand. This not only requires a considerable amount of force, but is also not without danger

for the operator, "velche yourself, the hand injure on spliced wires of the rope and their limbs may get caught in the loops of the slack pulling rope can. Another disadvantage of "known devices" arises when they are often necessary Deflection or redirection of the pull rope. Because the manure scraper does not run over the pulley can, the pull rope is removed from the Uialenkrolle shortly before the slide by means of a stop piece lifted out. The pull rope is exposed to very strong wear and tear. ”The invention is intended to address these and other disadvantages to eliminate the well-known stable clearing.

An essential idea of the invention is that the drive of the cable drum is electrical by means of a switch preferably arranged at the operating end of the manure scraper, in particular a push button switch controlled by. a power line running inside the hauling rope is connected to the electrical control and switching device of the cable winch. These Control current line is preferably in a special, from the power circuit of the electric motor separate weak circuit, e.g. via a

0098U / 0S8S

Isolating transformer is fed from the power grid. The operation of the control circuit enables a particularly simple design of the pull rope insofar as a Stromleitungsafcrang to the manual switch is formed by an insulated core strand of the pull rope, while the wire mass of the pull rope is used directly as the other strand of wire geki.

This ensures that the operation of the manure removal device is extremely simplified, The starting and stopping of the manure pusher movement is made easier and safe takes place without the difficult, dangerous and also unsafe tightening of the pull rope only by pressing the push button switch, with disruptive, separated from the pull rope Power cables are avoided. The pull rope can now be directly at the front end of the manure scraper be attached, which significantly improves the stability of the manure scraper and prevents it from tipping over of the slide is avoided. As a result, the manure scraper can be carried out more easily which in turn makes it easier to retrieve the manure scraper by hand.

The winch and its drive motor can be controlled by means of the pushbutton switch, the motor upon pulling the manure slide m a force-locking is coupled with the cable drum, switch operation while retrieving the Dungscliiebers the other hand, by repeated push button in a further embodiment of the invention is put into reverse rotation and having normally empty runs, but when a certain return speed of the manure scraper is exceeded, it is coupled to the rope drum again «It then acts as a brake and prevents dangerous backward movement of the manure scraper, as could occur when pushing manure on a steeply inclined path _a

The previously used in the deflection or redirection of the Difficulties occurring with the pull rope are according to a further essential concept of the invention simply 'quietly eliminated by the fact that the end of the Ziigseile with one of the rope groove the pulley adapted rope shoe is connected ρ the at the lower, free end of one at the front South of the manure scraper mounted pivot pin is'ö. This ensures that the Pull rope when approaching the manure slider to the

Deflection pulley smoothly out of the liolle's iSeilrille can run out without lifting the pull rope from the role is necessary. The so far Heavy strain on the pulling rope when the rope is excavated is avoided in this way and that The pull rope is released from the pulley without bumps or kinks. The service life of the pull rope is increased considerably as a result of this measure. The reduction is due to the live core of the pull rope the tension on the pull rope is of particular importance.

The stable clearing facility essentially consists of a ¹ sledge-like manure scraper 1 without a bottom, a pulling rope (wire rope) 2 and a rope winch 3.

The manure scraper 1 is provided with pneumatic tires 4 mounted on a pendulum axle , which are brought into working position when the manure scraper is returned, while the manure scraper grinds with its floor frame on the stable floor when moving manure. At the rear end of the control, the manure scraper has a handle 5 »on or close to which a push-button switch 6 is arranged. At the front end, the manure scraper 1 is provided with a deflector bracket 7 which carries a horizontal projection 8.

According to Figs. 1 and 3, the pull rope 2 runs from the one which is attached to a tubular steel mast 11, for example Cable winch 3 via a guide roller 10 mounted so that it can pivot horizontally at the upper end of this mast, either directly or via one or more pulleys 12 to the front end of the manure scraper.

The core of the pull rope 2 is a current-carrying wire strand 13 'at both ends the pull rope emerges from the same. -The wire strand runs through the manure scraper 1 the stiffening tube 9 to the rear to the one Zontakt of the push-button switch 6. The other contact of the child 6 is connected to the metal mass Jss wire rope 2, which in this case Q.Iü serves as a return line. This is permissible because of the ? ci. push button switch 6 to switch box 14 of the Cable winch 3 leading control circuit is only operated with weak current of e.g. 3 to 24 volts.

The end of the pull rope 2 which acts on the manure scraper 1 is inserted into a longitudinal bore 15 of a Cable shoe 16 introduced, in which it is held by means of a cable clamp 17. On the wider one At the end of the rope shoe 16, a hollow pivot pin 18 is rigidly attached. The pivot pin 18 is up

in a vertical bearing bush of the bracket projection 8 rotatably mounted and is in the latter by an adjusting screw 19 against falling out secured in a Hingnutsegment the pivot 18 intervenes. Due to the segment shape of the annular groove, stops are formed at the same time, which prevent the pivot from rotating completely through 360 °. The pivot with the rope shoe can thus be released from the manure scraper and attached to a feeder rake 20, for example will. This means that the device can also be used to bring green fodder into the stable. The Eeohen 20 is similar * to the manure scraper 1 provided with a push button switch. The different application and deflection options for the establishment are in Pig. 2 for example shown.

The ieitungslitze 13 is interrupted in the passage for Dungsohieber and a Steoke-rverbindung 21, 22, so that the power line during removal of the pivot pin 18 also unterbroohen and restored upon insertion of the rotary Zapfene% m ± may be.

The rope shoe 16 has a look after Zugseileinführung tapering cross-section, namely the side surfaces 23, 24 according to the Radius of the grooved rope bed 25 curved in an arc, in connection with the rotatable mounting of the Cable shoe 16 is thereby any kinking of the pull cable 2 when passing through the pulley avoided. At the same time, the projection 8 of the manure scraper 1 runs over the pulley 12, so that the pull rope with the rope shoe runs smoothly around the role when deflecting and a lifting of the Pull rope is not necessary.

Each pulley 12 is at the free end a support arm 26 rotatably mounted about a vertical axis 27. The other volume of the support arm is by means of a horizontal axis 25 at the upper end of a vertical support column 29 and up Can be swiveled down to the level of the pulley, e.g. in winter when there is ice and snow cover automatically adjust to the increase in the slideway of the manure scraper outdoors. The support column 29 can inserted rotatably into the bearing bushes 30 sunk in the floor at the * required deflection parts will.

According to FIG. 8, the cable winch 3 ~ consists essentially of a cable drum 31, an electric motor 32 with a flange-mounted reduction gear 33 and the switch box 14 that accommodates the switching and control devices simultaneously
the storage of the cable drum carries, a ratchet wheel 35 is keyed, which uit one on the inside
Jacket of the cable drum 31 rotatably mounted pawl 36 cooperates, which is under the action of a compression spring 37.

at the other end of the cable drum 31 that is The end of the pull rope 2 is guided out of the drum and clamped. The current-carrying Litzenseal is connected to a carbon brush 38 which is pressed against a slip ring 39 by a spring will. The slip ring 39 sits isolated on a stationary stub shaft 40 on which the corresponding The end of the cable drum 31 is rotatably mounted. The slip ring 39 is in turn connected to the switching and Control unit connected in switch box 14.

In the switch box are housed as essential elements, an isolating transformer 41, which the Heavy current from 220 volts to 8 volts, for example

transformed down, a low current operated impulse switch 42, a reversing contactor 43, a thermal overcurrent release 44 and a control fuse 45. In the weak circuit the push-button switch 6 located on the manure scraper 1 is also located is supplied via terminals 46. The entire electrical schematic is in Pig. 12th shown schematically.

The operation of the above described Stable manure removal facility is the following:

The manure scraper 1 may be inside -Ines stable at the rear end of a manure plate are located, which can be conveniently provided with a guide channel for the manure clip. After this the system has been energized by turning on a main switch, the push-button switch is activated 6 actuated. As a result, the reversing contactor 43 is operated via the impulse switch 42 in such a way that that the electric motor 32 is set in motion in the drive direction. The gear shaft 34 takes over the s «per wheel 35 and the pawl 36 with the cable drum 31, which disgusts the pull cable 2. The slide 1 starts moving and

0098 U / 0566 ^ oFSO «^ - -13-

pushes the manure in front of him to the desired depositing part of the fertilizer.

To stop the manure scraper 1 or to bring it back by hand, it is sufficient to press the push button switch 6 to be pressed a second time. As a result, the impulse switch 42 is thrown, the ^ endesehütz 43 brought into its other switching position and the sheet metal motor 32 reversed in the opposite direction of rotation. With this direction of rotation the pawl 36 is lifted from the catches of the ratchet wheel 35, and the engine runs idle. When pulling back the manure scraper 1 by hand, the pull rope unwinds from the freely rotating one Cable drum 31 from. If the backward movement of the manure scraper is a certain speed exceeds, the cable drum 31 catches up with the rotating ratchet wheel 35, and the pawl 36 lies down again into the ratchet wheel 35. The idling motor now has a braking effect on the cable drum and prevents a further increase in the return speed of the manure scraper. Through this accidents are prevented that occur when the manure scraper is inadvertently reversed quickly could occur on a sloping slideway. ., "^ - *
