Description

Anti-erosion cultivation equipment

Field of technology

The invention relates to an anti-erosion cultivating device comprising on the one hand a connecting frame, which is provided with means for connection to a three-point hitch installed on a mobile field machine and on the other hand a main frame on which working tools for tillage agricultural are mounted.

Prior art

When growing especially broad-leaved crops, it is important to keep maximum rainwater in the soil and to prevent the application of fertilizers applied to the soil surface or by spraying on the leaf. A suitable measure is the formation of anti-erosion pits, resp. ridges and dams.

To create them, anti-erosion cultivation devices were built, which are an additional part of planting or sowing machines, or when growing potatoes it is an additional part of cultivators and feeders. Although known anti-erosion cultivation devices can be used to gradually create furrows and dikes in the soil with the aid of appropriate tools, these anti-erosion cultivation devices do not allow the simultaneous creation and repeated restoration of these anti-erosion pits and dams either between rows or in the furrow. The non-complexity of soil treatment is the biggest disadvantage of known anti-erosion cultivation devices.

Agricultural implements are also known, which comprise a main frame on which work tools for tillage agricultural land are mounted. The main frame is provided with means for connection to a three-point hitch of a mobile field machine (DE 19752177 A), which is most often a tractor. There are a number of work tools, such as blades, discs, cultivators, etc. Unlike known cultivation equipment (eg CZ 289 482 B), this agricultural tool is not tied to use in individual special machines, but its single purpose, given the shape of the work tool used. tools (CZ 303 936 B), is similar to the previous one or its biggest disadvantage.

A common disadvantage of the prior art is that an anti-erosion cultivation device is not known, with the aid of which it would be possible to form a growing area in one operation according to the requirements of different crops. This disadvantage stands out especially when planting and early treatment of potatoes in a potato planting system and also when sowing broad-row agricultural crops, such as maize and sugar beet, and when planting various vegetables.

The essence of the invention

This disadvantage is substantially reduced by the anti-erosion cultivating device according to the invention, which comprises on the one hand a connecting frame provided with means for connection to a three-point hitch installed on a mobile field machine and on the other hand a main frame on which working tools for tillage. The main frame is fixedly connected to the connecting frame and at least one reversing lever is pivotally mounted on the main frame about a transverse axis perpendicular to the direction of movement of the field machine. The single-return lever is equipped with at least one working tool selected from the group of static and rotary working tools. The group of static working tools includes in particular a fence-forming blade and a thickener. The group of rotary work tools includes in particular a punching wheel, a paddle wheel and a lifting wheel. Static work tools are slidably mounted in the vertical direction on the single-return lever. The rotary working tools are mounted on the single-reversing lever for rotation about an axis of rotation which is parallel to the transverse axis. Rotary work tools are slidably mounted with their bearings in the heights provided with vertical guides. Both static working tools and rotary working bearings

- 1 CZ 305865 B6 tools are coupled to a locking device for fixing the set position. The single-return lever is slidably mounted on the main frame and equipped with a fixing device for locking the set position. In order to prevent excessive immersion of the working tool in the ground, a vertical swing limiter is provided between the main frame and the reversing lever, preferably formed by a chain which is suspended between the upper cross member and the reversing lever.

For reliable ground pressure, the single return lever is provided with a pressure source selected from the group consisting of a weight attached to the single return lever, a spring open between the main frame and the return lever and a hydraulic cylinder mounted between the main frame and the return lever.

The advantageous connection of the main frame with the connecting frame is stationary, but detachable. For this purpose, the main frame comprises a lower cross member and an upper cross member, which are connected by at least one strut. The lower cross member is detachably connected, preferably screwed, to the connecting frame and to the stand and the connecting frame is a detachably connected, preferably screwed, winding jumper.

With this construction of the main frame, the single-return lever is pivotally mounted in hinges, which are slidably mounted on the lower crossbar and provided with a fixing device for locking the set position.

In order to be able to reliably park the anti-erosion cultivating device with the necessary working tools, one element selected from the group comprising the main frame, the connecting frame or the single-return lever is adapted to fasten a removable parking support.

For easier forward movement, especially in the case of a trailer, a foot is connected to each side of the anchoring element selected from the group comprising the main frame and the connecting frame, at the lower end of which a travel wheel is mounted. The leg is pivotally connected to the anchoring element, and a length-adjustable strut is provided between the anchoring element and the leg.

Example of an embodiment of the invention

The basic parts of the anti-erosion cultivation device are the main frame 2, the connecting frame 1 and at least one single-reversing lever 3, which is adapted to connect the working tools 4 (Fig. 1).

The connecting frame I is provided with means for connection to a three-point hitch, which is installed on a mobile field machine. A field machine means both an energy source, in particular a tractor, and a trailed machine, which is in particular a planter, a seed drill or another connected machine with a minimum distance between the energy source. The connection of the connecting frame 1 with the three-point hitch can be in the form of a supported or a trailer version.

The main frame 2 is fixedly connected to the connecting frame 1. The main frame 2 comprises a lower cross member 22 and an upper cross member 23, which are connected by at least one strut 24. In the exemplary embodiment, three struts 24 are applied for strength. 1 is stationary, but is designed to be detachable so that the lower crosspiece 22 is screwed, e.g.

-2GB 305865 B6 by means of bolts 12 and their corresponding tightening nuts 14 to the connecting frame 1 To the stand 24, resp. the wind brace JJL is detachably connected to the struts 24 and the connecting frame 1, for example by means of a connecting pin 13

At least one single-reversing lever 3 is pivotably mounted on the main frame 2 about a transverse axis 21 perpendicular to the direction of movement of the field machine. Fig. 1 shows three single-reversing levers 3, while in Fig. 3 there are five pairs of these reversing levers 3. The advantageous mounting of the single-reversing levers 3 consists in that they are pivotably mounted by means of hinge pins 36 in hinges 34 which are slidably mounted on the lower crosspiece 22 and at the same time provided with a fixing device 35 for locking the set position. The fixing device 35 is similar to the horizontal brackets 37 by which the lower crosspiece 22 is encircled and on which hinges 34 are fitted on the opposite side and lock nuts 38 are screwed in. To limit the swing, a vertical swing limiter 6 is provided between the main frame 2 and the reversing lever 3. Its simple and reliable design is formed by a chain 61, which is suspended between the upper cross member 23 and the single-return lever 3 (Fig. 5).

Working tools 4 for tillage agricultural land are mounted on the main frame 2 by means of reversible levers 3. The working tools 4 are selected from the group of static and rotary working tools, of which the group of static working tools comprises in particular a fencing-forming blade 41 (Fig. 1) and a grater (not shown) and a group of rotary working tools in particular a punching wheel 42 (Figs. 3), a paddle wheel 43 (Figs. 3, 4) and a lifting wheel 44 (Fig. 5). The rotary working tools are mounted on the single-reversing lever 3 rotatably about an axis 31 of rotation which is parallel to the transverse axis 21. Static working tools are slidably mounted on the single-reversing lever 3 in the vertical direction and the rotary working tools are slidably mounted by their bearings 45 at provided with vertical guides 33 of the bearings 45. Both the static working tools and the bearings 45 of the rotary working tools are coupled to a locking device 5 for fixing the set position. The locking device 5 most often comprises a screw device with either a horizontal screw 51 (Fig. 1) or a vertical screw 52 (Fig. 2). Particularly in the case of hard soil, it is necessary to increase the pressure of the working tools 4. For this purpose, the single-reversing lever 3 is provided with a pressure source 7. The pressure source 7 is selected from a group of means such as a weight 71 attached to the single return lever 3 (Fig. 5), a spring 72 open between the main frame 2 and the single return lever 3 (Fig. 4) and a hydraulic cylinder 73 mounted between the main frame 2 and single reversing lever 3 (Fig. 2).

For stable off-road driving, it is suitable if a leg 9 is connected to each side of an anchoring element selected from the group comprising the main frame 2 and the connecting frame 1, at the lower end of which a travel wheel 91 is mounted (Figs. 1, 2). In the exemplary embodiment, the anchoring element is a connecting frame 1. The leg 9 is pivotally connected to the anchoring element, i.e. the connecting frame 1, by means of a first bearing pin 93. A length-adjustable strut 92 is provided between the anchoring element and the leg 9, which is rotatably connected to the leg 9 and rotatably connected to the anchoring element by means of a second bearing pin 94.

One element selected from the group comprising the main frame 2, the connecting frame 1 or the single return lever 3 is adapted to fasten a removable parking support 8, which is intended to support the device during a work break. In Fig. 1, the support 8 is adapted to clamp the single-return lever 3 by means of a vertical bracket 81. In a non-illustrated embodiment, which is particularly advantageous, the support 8 can be height-adjustable.

Before starting the operation, the device is assembled into the required configuration. Hinges 34 are attached to the main frame 2 at spacings depending on the row spacings, together with the single-reversing levers 3. The working tools 4 are attached to the single-reversing levers 3 and are height-adjusted. The length of the vertical swing limiter 6 is defined, while at the same time, if necessary, the single-return lever 3 is loaded by a source 7 of pressure. The main frame 2 is firmly connected to the connecting frame 1. The connection is strengthened by anchoring the wind bridges 11. The position of the leg 9 with the travel wheel 91 is also adjusted. This unit is attached to the three-point hitch of the tractor, resp. behind the tractor of the engaged field machine.
