Definitions
- the invention relates to the field of cleaning livestock buildings.
- the invention relates to a drive device in translation of a scraper member.
- the invention is particularly intended to cause a planer designed to push slurry, soft manure, or strawy or thick manure out of the corridors or stabulations of a barn.
- a disadvantage of this known technique is that an infrastructure must be provided to guide the soft strand of the chain along the entire length of the building.
- the invention therefore particularly aims to overcome the disadvantages of the state of the art mentioned above. More specifically, the invention aims to provide a drive technique in translation of a scraper member that is reliable and requires very little intervention and maintenance and maintenance operations.
- an objective is also to provide such a drive technique that does not require adjustment when the chain is extended.
- An object of the invention is also to provide such a drive technique that allows the scraping of any type of manure.
- Another object of the invention is to provide such a technique that is simple to install, and a reduced cost.
- An object of the invention is also to provide such a technique that is easy to use.
- a device for translational movement of a scraper member of at least a portion of the droppings covering a corridor of a building comprising a chain intended to be secured to the scraper member and actuated by means of a first motor.
- a drive device comprises a first nut secured substantially to a first end of the chain and a second nut secured substantially to a second end of the chain, the first nut being adapted to be rotated by the first motor and the second nut being adapted to be rotated by a second motor in the opposite direction of the first nut,
- the invention proposes to use two motors to pull the plane in one direction or another, by turning each motor.
- the drive device according to the invention is particularly small and simple to implement. It also requires very little maintenance.
- the training device which is the subject of the invention comprises one or more of the following characteristics, according to any operative technical combination.
- the first motor and the second motor are gear motor motors.
- geared motors rotating at a typical speed for example 1500 rpm under 50 Hz, provides a high output torque capable of towing a large load. In addition, it allows to move the scraper slowly, which allows free animal housing in the corridor, without fear of fright or injury.
- a drive device as described above comprises a first guide pulley of the chain, mounted between the first nut and the portion of the chain intended to be secured to the scraping member.
- the implementation of a pulley keeps the chain close to the ground along the length of the corridor while protecting the engine, which can be placed in height, slurry and / or manure covering the ground.
- the device comprises a second guide pulley of the chain, mounted between the second nut and the portion of the chain intended to be secured to the scraper member.
- the first nut, the first motor and the first pulley are mounted on a first one-piece support.
- the first one-piece support has hooking means for its transport.
- the monoblock support can thus be moved easily and be put in place quickly.
- the first pulley is positioned under the first nut, substantially to the right of the latter.
- the device comprises a storage box for receiving the first end of the chain when the first nut is rotated.
- the soft strand of the chain flows into the storage box and does not pile up disorderly on the ground, which limits the grip of the training device on the ground.
- the first and second nuts have a plurality of fork protrusions each for receiving a link of the chain.
- the axis of the first nut and the axis of the shaft of the first motor are horizontal.
- the chain is secured substantially in the middle to the scraper member.
- a device as described above comprises means for coupling said nuts with said motors, able to take at least two positions:
- Figure 1 is a perspective view of a scraper pull module presented with reference to Figure 5;
- Figure 2 is a side view of a drive shaft for marine chain according to the invention.
- Figure 3 is a sectional view along section A-A of the drive nut shown with reference to Figure 2;
- Figure 4 is a detail view of a fork of the drive nut shown in Figure 2;
- Figure 5 is a schematic perspective view of a manure scraper and / or slurry.
- FIG. 5 there is illustrated a wiper 550 equipping a barn 500 comprising a stall space 510 and a corridor 520.
- the scraper 550 is formed of a plane 560 driven in translation by a device 505, comprising two complementary identical traction modules 100A and 100B and a chain 160 fixed in the middle to the plane 560.
- the traction modules 100A and 100B are arranged at each end of the corridor 520 to be cleaned.
- One of the two traction modules 100A is intended to pull the plane 560 so that it pushes the waste bulky corridor 520 to a pit at one end 540 of the corridor, while the other module 100B is intended to shoot and thus bring back the plane in its initial parking position 530, located at the other end of the corridor.
- the plane 560 is guided by a slider 565 cooperating with a guide groove 525 formed in the floor of the corridor 520.
- one of the traction modules 100A or 100B is activated, it draws the plane by setting tension the chain portion 160 called stranded strand 162, the second traction module 100 is inactive, running freely the chain portion 163 forming a soft strand.
- the traction module 100A comprises a frame 150 mounted on a base 105, supporting at its top a geared motor 110 on the shaft of which is mounted a drive nut 200 disposed vertically of a return pulley 130 and a crate 140, also called tray, chain.
- the pulley 130 is mounted on the base 105, substantially at ground level and is aligned with the guide groove 525 of the plane, formed in the floor of the corridor 520.
- the chain portion 164 is stored in the tray 140.
- the pulley 130 has a guide groove 132 shaped to best maintain the chain 160 in place.
- This groove 132 has a width substantially greater than that of a link of the chain 160 and a depth substantially equal to half the width of the link.
- the winding arc of the chain 160 around the nut 200 is greater than 90 °.
- this winding arc is between 120 ° and 180 ° and preferably between 145 ° and 180 °.
- the bottom 141 of the tray 140 is perforated and raised by feet 142.
- the perforated bottom 141 allows, in addition, the evacuation of the rainwater that would otherwise accumulate in the tank 140 when the traction module 100A is located outside a building.
- a control module supplies electricity to the gearmotor of the traction module 100A and switches off the power supply of the gearmotor of the traction module 100B, which becomes inactive. Conversely, to return the plane 560 to the parking position 530, the control module cuts the power supply of the gear motor of the traction module 100A and supplies power to the geared motor of the traction module 100B, which becomes active.
- a mechanical coupling such as a clutch for example, is mounted between the motor shaft of the gear motor 110 and the shaft bearing the nut 200.
- This mechanical coupling can be temporarily rendered inactive and can engage or to disengage the nut 200 of the geared motor according to whether the pulling module which carries it is activated or not.
- the pulling module which carries it is activated or not.
- FIGs 2 and 3 show detailed views of a drive nut 200 fitted to the traction modules 100A and 100B illustrated with reference to Figure 1, respectively side and section.
- the walnut 200 is formed of a hub called cylindrical core 210 and two circular flanges 220, welded to the core 210 and delimiting a first groove 215 still called principal.
- the flanges 220 extend beyond said groove over a height 260 of 45 millimeters.
- the flanges 220 comprise, on the internal face 221, teeth 240 of radial orientation spaced at a regular pitch.
- the two teeth 240 of the two flanges 220 are arranged vis-à-vis, each pair of teeth forming a fork 249.
- Each tooth 240 of one of the forks 249 has a similar profile according to the axial orientation of the nut, with a substantially constant width having two flanks with substantially parallel faces and rounded edges.
- the tooth 240 of the fork 249 shown in detail in FIG. 4 has a height h according to the radial distance between a foot circle corresponding to the diameter df of the cylinder forming the core 210 and a head circle of diameter d a delimiting the vertex of the tooth 240 of the fork 249.
- This height h of the tooth 240 of the fork 249 includes a projection height h a and a height hf hollow.
- the hollow height hf corresponds in the proximal portion 244 of the tooth 240 of the fork 249 to a base 241 of constant thickness.
- the tooth 240 of the fork 249 has a recess 242 in its thickness.
- This recess 242 is the beginning of a portion 243 corresponding to the projecting height h a in which the thickness decreases uniformly to the distal end of the tooth 240 of the fork 249.
- the distal end tooth 240 is tangent with the inner face 221 of the flange 220.
- the dimensions of the nut and the pitch between each tooth 240 of the forks 249 are a function of the size of a mesh of the chain used.
- the thickness of the tooth 240 at the base 241 is such that between two teeth 240 vis-à-vis the fork 249, remains at the right of the throat 230 secondary, a space of dimension substantially greater than or equal to the section of a link of the chain 160.
- the tooth 240 of the fork 249 further comprises sidewalls 241 and 242 substantially parallel.
- the inner faces 221 of the flanges 220 are substantially parallel.
- Two successive forks 249 delimit a housing 250 for a chain link 160 to be driven.
- the flanks 241 and 242 of the teeth 240 of the forks 249 then serve as stops for the link of the chain 160 inserted in the housing, transmitting by contact the force produced by the geared motor to the chain 160 which is pulled.
- the chain can twist in the nut 200, without jumping and therefore continue to be driven by the nut 200. Similarly, the drive is assured even if the chain is completely tensioned, under the effect of the traction.
- a second groove 230 is formed on the core 210.
- This secondary groove 230 has a dimension in width substantially greater than or equal to the section of a link of the chain and at depth substantially greater than or equal to half the section of a link.
- the centering of the nut 200 on the motor shaft of the geared motor is provided by a central bore 231 formed machined in the core 210.
- This core 210 comprises in the axial direction of the bore a groove 232 to maintain in rotation by keying the 200 nuts on the shaft of the gearmotor.
- the core 210 of the nut 200 extends outside one of the flanges 220, along its axis, in the form of an outer cylindrical portion. This extension of the core makes it possible to equip the traction module with a brake in the form of a belt or a strap acting by friction on this outer cylinder.
- the assembly formed of the core 210 and the flanges 220 is obtained in casting by molding.
- the technique described above for making a chain drive nut can be used in different types of traction equipment or pulleys, for example to form a traction element of a chain of a lifting system or a docking system in a floating structure such as a ship, a platform or other.
