NL8902212A - Deterrent to prevent crushing of sucking pigs - uses high pressure cold air flow to drive piglets away from sow when she stands up - Google Patents

Abstract

The present device detects the sow's movement and sends a blast of cold air onto the floor of the sow's pen. The piglets move back into an area which is electrically warmed until the sow lies down again and the air flow stops. An infra red sensor on the rail supports of the sow's pen operates delay and causes a fan at the top of a pillar to operate, drawing in air (aanzuigen). The air passes down the pillar and is blown out (uitblazen) across the floor. Power to the fan, sensor and relay is fed from a conventional mains supply plug (stekker) and manual on/off switch (stopcontact).

Description

Piglet hunting with ventitaton with a capacity of more than 180 m3 / h to combat piglet mortality. to go.

The invention relates to a piglet hunting with a ventitaton with a capacity of more than 180 m 3 / h in order to prevent piglet mortality. The patent application is limited. to the details of the piglet veneer, namely the ventitaton.

the hitherto known piglet fighter, which draws in the barn air and blows away teect from the sow, has a ventilation capacity of up to 160 m3 / h.

It has been found in practice that it is not possible to bring the average dead lying percentage below 1% dead on a year basis, the newly developed hunting has a ventitaton capacity of 4-10 m3 / h, and is able to achieve an additional to build a high pressure.

This principle gives the chase air, but the higher capacity and will therefore make it air vent less.

Pneven in the practice has shown that the dead-end percentage is below 1% on a year basis, which is the reason for applying for a patent on dinecte piglets, hunting with a ventitaton capacity of more than 180 m3 / h.

In addition, a negligent infna-emergency senson, possibly for cooling, and a socket for the piglet-lamp (constant theme) have been used.

On page 8 you will find a hint of the piglet hunt. On sheet 5, fig. 1, 3 and 4 depict the piglet hunting and fig 2 the part of the pig gene hunting gene, in which the ventitaton is located.

On pages 6 and 7 you can see the hint of the piglets' calves, according to pages 6, fig. 5 and 6, confirmation in the box and sheet 7, fig. When the sow wants to lie down, the piglets are not in any case present under the sow, so that the deadly pigging is practically impossible, so that these piglets are not pleasantly cold enough to hunt so many of the piglets.

2, C his devensen jLactonen think about why a sow will stand up when the lying cock fetches their food, while the lying down will pnolen and so will the sow come up with the chance to wound to death when this crying, moon When the lie-hunter beckons, the air stnoom, the present ones will seek their salvation, which is why the object of this invention has been lied to, 3, Since this device is designed in a tactile and universal way, which can be installed in all of the existing pubs and is easy to move with a single light operation, these lying floors have a ventilation capacity of. then mean. 400 m3 / h. Disciplinary description is an invention and unique in its Aoont. Moreover, that characterized doon woud the good and ty sond well. a-jLwe.fik.ing and duu / izaam.h.e.id of the used high-quality materials, 4.
