Method in connection with an assembly trolley and an assembly trolley

The invention relates to a method in connection with a collection trolley, which collector trolley is preferably intended to be towed behind a towing device, such as a vehicle, a working machine or the like. The collection trolley has a substantially rectangular container for the transported material formed on at least one substantially horizontal base and vertical side and end walls, coupling members at the first end of the collection trolley, such as a drawbar or the like, for transmitting force to the container, and at least at the other end. motion members such as rear wheels, rollers and / or the like.

The hopper tank is emptied in cross-section in the downward direction by tilting the bottom parts to empty the material in the tank through the respective emptying openings 20 in the hopper, the bottom of the hopper being formed in cross-section. by tilting the parts belonging to the base by means of force elements acting in a substantially vertical direction, arranged in a substantially closed body in the middle of the container: preferably in a substantially closed position.

The above types of assemblies are used in a wide variety of contexts. One typical • · · application is the collection of peat. In this case, the peat collection on the field is: • 35 peat, after which the collected peat is transferred by the collection trolley to the emptying site, where it is emptied either by the traditional unloading method, ie by opening one side of the collection trolley and tilting 2 101141 full collection tanks or other advanced using. The above-mentioned conventional unloading method has a number of drawbacks, one of which is that when the collection container is emptied, the center of gravity of the entire collecting carriage changes. Because the collection wagon is usually handled on relatively soft ground, a change in focus often even results in the collection wagon overturning. Due to the soft soil, the collection trolley also often tends to sink 10 from the other side into the ground during emptying, so that relaunching the collection trolley is often a very laborious and time-consuming operation. In addition, the emptying of the collecting tank belonging to the collecting trolley is often vague when using traditional "tipping" tanks, whereby in the first place part of the contents of the collecting tank easily remains attached to its walls. On the other hand, part of the contents of the collecting tank discharges under the collecting trolley, where it usually mixes somewhat with the soil when the collecting trolley is moved due to overrun.

In order to eliminate the problems associated with the above-mentioned conventional unloading method, for example, a device 25 for collecting and filling milled peat is previously known from Finnish patent No. 61913, in which the collecting carriage container opens below and in which the collecting opening includes a rear opening substantially at the discharge opening at the bottom of the container. wheels. In this case, the peat discharged under the opening 30 of the collector can in principle be sealed tightly with the above-mentioned wide wheels.

35 There are, in practice, certain advantages to this method,

'but also quite significant drawbacks.

• ·

Firstly, it is very common that the tank 3 101141 of the collecting trolley does not empty evenly on both sides, but tends to empty unilaterally despite the fact that the bottom of the tank opens symmetrically completely. In practice, this one-sided unloading very often results in the collection wagon falling over the peat unloaded on the pit. Thus, the situations in which the collection wagon empties at just the right doses into suitably flat ridges are very random, especially in certain circumstances, 10 which is why the application of this type of method is not very common.

However, since emptying the collection trolley to the side has thus proved to be more advantageous in a certain sense, e.g. Finnish Patent Application No. 932243 discloses a method and transport trolley suitable for a similar purpose, in which the trolley is emptied, e.g. by moving one side wall of the container between the walls to empty the material in the container through the discharge side, which is achieved by opposing the movable side wall: “by moving the side wall out of place. That: 25 solution therefore works in the so-called through the push-through principle, in which case it may be possible to II * improve the emptying of the vehicle. However, this solution is relatively complex in terms of both practical implementation and construction, and requires disproportionately high-performance actuators.

On the other hand, it is previously known, for example from SE publication 417080, to empty e.g. a container in a collection trolley with its bottom parts facing downwards by tilting the material in the container through the corresponding emptying openings in the collection trolley. In this embodiment, the bottom of the collecting carriage is formed in cross-section from two bottom parts movable relative to the body of the collecting carriage, which are moved in opposite directions when viewed in cross-section by tilting the bottom parts by means of force elements 10 Since in this collection trolley the discharge opening is arranged between the wheels in the middle of the trolley, a strongly conical structure has to be used as a tank. For this reason, it is not possible to dimension the collection trolley optimally, but it is significantly smaller in volume than the solution made possible by the present invention. In addition, however, a solution of this type may not be able to ensure the efficient emptying of the tank, for example when treating water, e.g. the vaulting effect is not achieved by the so-called. to break down.

; The object of the method according to the invention is to provide a decisive improvement over the above-mentioned drawbacks and thus substantially increase the state of the art. In order to achieve this object, the method according to the invention is mainly characterized by M *::: that the container is dismantled 30 by moving the opposite side walls of the container out of place, in addition to said bottom parts, substantially due to the movement of the side walls of the emptying openings formed on each side of the collecting carriage.

Of course, it is also possible to carry out the method on a one-piece base which is tilted only at one edge. However, such a construction may have the disadvantage of the heeling and one-sided subsidence problems inherent in traditional solutions, although probably to a much lesser extent.
