DE19711305A1 - Tubular probe for taking ground samples - Google Patents

Abstract

The probe for taking ground samples consists of a tubular shaft (1) with a T-shaped hand grip at the top and a point (3) at the bottom. A long slit (4) extends upwards along the shaft to the point. A tube section (6) with a pedal (9) on the side can be slid or fixed on the shaft and is secured over the shaft by a clamp (7). An emptying piston (12) can be moved within the shaft. The pedal position can be fixed according to a scale (5) on the lower part of the shaft. This enables the user to take samples at a predetermined depth.

Description

The invention relates to a device for removing Soil samples using a tubular probe.

For farms are recently Row floor examinations are mandatory. From Extraction equipment sold by soil testing institutes consist of an approx. 50 cm long metal tube. To advance in the bottom and pulling out serves in the T-joint above welded handle. So that the pipe is better with Fills the bottom, this is 2/3 of its length with a bottom Provided slot.

Taking soil samples with the device designed in this way must be in a stooped posture and requires in this a lot of effort. Very time consuming and cumbersome is also the emptying into the receptacle. The The soil sample is applied by introducing a pointed narrow object in the slot and Scrape out the floor with the same. With the usual at least 15 samples per ha for testing purposes the work and time required is extremely large. There is also an accurate record in each prescribed floor depth hardly possible.

The invention is intended to remedy this and is based on the task out, an easier to handle and also on the required ram depth adjustable To create soil removal device.

The object is solved by the features of claim 1.

The advantages to be achieved by the invention are as follows:

• - Little effort to take the soil samples;  
• - Possibility to adjust to the desired depth the adjustable, the depth of penetration into the ground limiting, pedal;
• - Determine the pedal position using a scale on Tubular shaft;
• - Inexpensive way of expanding with a simple and does not require much time Floor ejector.

The device is shown in Figs. 1 and 2 in front and side view, in Fig. 3 in the position in which the user uses it. This grips it by the handle 2 and places it on the floor at the point of removal from the floor and rams it with the foot on the pedal 9 into the floor until the pedal sits on the floor 13 . Due to the predetermined depth of penetration of the tubular shaft into the ground based on the scale 5 , a quantity of soil corresponding to the penetration depth is extracted in each case. As can be seen in FIG. 1, the pedal 9 is fastened at the bottom to a sliding tube 6 which can be displaced axially on the tubular shaft 1 . Above, the sliding tube is designed as a locking mechanism 7 which can be actuated by the handle 8 and can be fixed on the tubular shaft 1 by this. The scale 5 can be adjusted by moving the slide tube 6 .

A tube slot 4 can be seen in FIG . As shown in FIG. 1, the pedal 9 is reinforced at the bottom by a ring 10 and a flat bracket 11 which projects into the tube slot and to which an emptying piston 12 is fastened is attached to this.

After the locking mechanism 7 has been unlocked, the soil sample taken can be easily emptied into a container provided by pushing the pedal down to the tip. A stop 14 arranged at the bottom of the tubular shaft 1 prevents the sliding tube 6 from sliding out.
