Description

The above-mentioned invention is also a human-powered roller bed used mainly for cultivating backyard farms and small gardens.

He knew that backyard and horticultural as well as greenhouse and foil tent production required tillage operations such as plowing, soil loosening, weed control, rooting, irrigation or other furrow pulling, potato filling and de-frosting, and spring opening.

Currently, these operations are mostly performed by hand-operated tools, e.g. with a spade, hoe, trimmer and other hand tools, as well as with higher productivity garden tractors, conventional animal beds, plow hoes. In most greenhouses, foliage tents, low-crown trees and narrow-row vines, orchards, and corn, sorghum, sunflower and other row crops, the aforementioned operations cannot be performed with garden tractors or animal tow devices due to the tight space, in these places, only hand tools and heavy work can be done by digging, plow and furrow replacement, plowing and picking potatoes, and covering vines, tree branches with frost, and opening in the spring. For example, the vines need to be close to the cultivator when they are covered or opened, so that these jobs cannot be done without damage to a garden tractor or animal towed device. In addition, animal towing costs a lot to keep the towing animal and usually requires two people to tow the animal. One who controls the cultivator and the other who drives the towing animal.

The price of a garden tractor is very high. Garden tractors are powered by an import engine, which engine parts quickly wear out. Importing an engine part is very expensive and replacing the part and the whole import engine is a constant currency barrier. Garden tractors require imported petrol and oil. This makes the operation of garden tractors very expensive.

A man escapes from the polluted air and noise of his residence to his garden, where, when he uses a garden tractor, he carries with him a garden tractor that is much more polluting and noisy, which is heavily polluted by the polluted air of his residence.

The bedding used today for plowing consists of a plow head and a plow mounted on the plow body, and a coulter that extends from the plow frame to the beam, which vertically splits the furrow slit, flip it over and lightly chop it.

The plow body, which is propelled by moving the ground in a forced path to the furrow wall, is mounted on a hard metal plate, which components in the soil have high resistances which require high traction, since these conventional beds slide with a high resistance at the bottom of the furrow.

'The coulombs, which extend from the frame, the beam to the soil and vertically cut off the soil, the melons, pumpkins, cucumbers, potatoes, potatoes, corn, sunflower, tobacco pathogens, other plant residues are clogged, .

No. 145,669. Hungarian Patent Specification describes a roller harrow in which the steering plate is mounted on a roller surface with self-cleaning rotary cultivating bodies having a wear-resistant surface; steering wheel rollers, and the sliding friction metal plate echo cane is replaced by a self-cleaning abrasion-resistant ecenad roller.

According to tests and practical experience, these rotary plow heads have a 25-35% lower traction power than their equivalent tiller, with the same plowing width, depth and soil quality.

The common disadvantage of the aforementioned known plows is that the coulter, whether it be a disc coulter or not, which passes in front of the plow head, is fixed to the plow frame, plow frame and beam through a lever. Therefore, when plowing soils covered with melons, pumpkins, cucumbers, potatoes, corn stalks and other plant residues, the coulter fixing arm and the frame, gathered in a beam, cause these crop residues to break the plow, thus preventing further plowing. In such cases, the plow must be stopped and the tractor cleaned of clogging, resulting in heavy work, time and area loss.

As a result, riders regularly remove the coulters from the plow, which has the detrimental effect that the front wall of the furrow is formed by tearing, crushing and breaking the front edge of the tiller plate, resulting in a significant increase in traction and fuel consumption, as well as .

The big disadvantage of the beds used today is that they not only have a great resistance in the soil with their joystick plate, their echinoderms, but also with the heavy weight of the split furrow, soil profile applied to the plow head, the plow to the furrow bottom . This further increases the need for traction and, in addition, causes a mole disorder in the soil at the bottom of the furrow by compaction.

The object of the present invention is to eliminate the disadvantages and shortcomings listed above, i.e. to create a soil cultivating bed for small-scale operation, which is capable of operating by human power with low traction, clogging, solving the mentioned tillage problems, , also suitable for export.

In order to complete the task, I started from a well-known roller bed with a plow attached to the trunk, a roller coaster and a coulter mounted on the frame in the towing direction behind the coulter fixed to the frame. This was further developed in accordance with the present invention in that the coulter is formed from the bottom of the plow nose upwards to the plow head height and retracts to the plow body as a hidden coulter.

Namely, the so-called hidden coulter according to the invention does not protrude into the ground from the plow frame, but rather from the beam: .

The hidden coulter according to the invention is formed by a baffle plate fixed to the plow body by means of screws with recessed head. Thus, it may need to be replaced easily and quickly, or sharpened quickly

The ecenad roller is adjustable in a vertical position. Reaching out of the plow frame, frame, and beam outside of the upright roller with adjustable vertical position! adjustable width, lateral and vertical depth adjustable plastic impeller, which prevents the roller blade from sliding to the bottom of the groove or frictionally in the same way as a conventional plow, it also results in the elimination of the ulcerative disease caused by the beds known today. In addition, the eccentric roller and depth adjusting wheels allow the hidden coulter and plow to enter and operate at an optimum angle to the soil so that the energy requirements of the hidden coulter and plow are kept at an optimum position.

On the plow frame, the beam is arranged in a forward position so that the weight can be laterally displaced and flipped in its displaced position for optimum cultivation of grapes and other rows of plants.

The base rollers and the ecenad roller base are preferably made of non-corrosive, lightweight, low-cost machining hard PVC or other suitable plastics material, the surface of which is preferably made of self-cleaning, abrasion-resistant, microporous foam rubber or other similar properties. The tiller rollers are arranged relative to one another so that the slice of the soil is perfectly turned and crushed to form a rotating twisted steering surface instead of the tiller plate.

The invention will now be described in more detail with reference to the accompanying drawings, which illustrate an exemplary embodiment of the present invention.

Figure 1 is a right view of an exemplary embodiment of a human-powered roller bed of the present invention.

Figure 2 is a left view of the solution of Figure 1.

Figure 3 illustrates, by way of example, the positioning of the weight box and the depth-adjusting wheel on the roller bed frame and beam of the human-actuated roller beds shown in Figures 1 and 2, as well as their locking position.

4/4 in the drawing, Figure 4 is an example of an ecumen roller! Figure 5 illustrates an exemplary embodiment of the steering roller.

As shown in the drawings, in this case, the roller beds of man-driven roller bearings have a frame 3, made of a thin-walled steel tube, welded or riveted by two metal sheets 1, inserted into the tubular part 2 of the upper end 2 is fixed by welding. The plow body 6 has a horizontal cutting edge 6 with countersunk head screws, while the right-hand plow body also has countersunk head screws 35 and the baffle 4 and its hidden coulter 5 are releasably secured.

According to the invention, a hidden coulter 5 operating in the soil to the depth required in the working position is formed as a vertical cutting element which reclines from the nose 6. In this case, the cutting edge of the hidden coulter 5 has a slightly curved design. (Figure 2). The cutting edge of the hidden coulter 5 covers the plow body 1 in such a way that the furrow wall formed by it is not in contact with, and frictional with, the plow body 1 (Fig. 2). The hidden arrangement of the hidden coulter 5 formed from the upper part of the baffle plate 4 is not prone to clogging, but at the same time gives the plow body a good penetration into the ground.

Behind the plow 6 and the hidden coulter 5 and the baffle plate 4 and in connection therewith, the steering rollers 24 and 25 are pivotally mounted in a twisted rotary surface arrangement. These steering rollers are fastened to the brackets holding the lower and upper steering rollers 22 with nuts 26 at their ends 58.

24 and 25 have the same length. While the two steering rollers 24 have the same diameter, for purposes of arrangement, 1/3 of the steering roller has a diameter equal to 2/3 of the steering roller 24 so that the base of each plastic roller tube is the same length and diameter but has a self-cleaning, abrasion resistant , the rollers have different thicknesses.

The steering rollers 24 and 25 are thus arranged to provide a suitable twisted surface for good rotation, comminution and mixing of the excised soil section.

The self-cleaning, abrasion-resistant surface of the 34 eenad rollers is made of the same material as the steering rollers. The eagle roller 34 is pivotally mounted on the shaft 45 of the eagle roller 27 and 28, pivotally attached to the plow body 1 by means of a nut 54.

The vertical position of the plow body 1 and the roller 34 can be adjusted to the shafts 27 and 28 with a right and left-hand threaded padlock, which adjusts the angular position of the hidden coulter 5 and the plow 6 with respect to the pulling direction. and can be reduced, so that the angle of the hidden coulter 5 and the cutting blade 6 can be adjusted to an optimum value depending on the condition and quality of the soil to be cultivated.

The tubular frame 3, at the front end of the beam, has a height adjusting fork 15, which is secured to the draw bar 14 by a retaining bolt 16 located at the rear of the fork 15. The traction height is controlled by means of an adjusting screw 17 inserted into the corresponding hole in the fork 15. The grip of the drawbar 14 is secured by a handle placed in the retaining bracket 18.

The tubular frame 3 is mounted on a rectangular plate 11 mounted on a beam, having a laterally displaceable rectangular cross member 38 which may be secured to the rectangular holder 37 by a threaded screw 36 which is threaded into the rectangular holder 37. At the two ends of the rectangular cross-member 38 is a welded rectangular bracket with an anchorage screw 13, in which the shaft of the depth-adjusting wheel 10 is adjustable vertically and can be secured to the position of the anchor bolt 13. These two depth control wheels 8 are adjustable transverse to the tubular beam 3 in the rectangular bracket 37 by the rectangular bracket 38, secured to the working stability of the roller bearings and secured there by the ear screw 36.

While the two depth adjusting wheels 8 can be slidably up and down by means of the depth adjusting rod 10 in the vertical direction and secured in position by the filament screw 13 in the position corresponding to the required depth or height. The two legs of the depth control 8 are removable from the bracket 12. The two depth control wheels 8 can be reversed or reversed if stability of the plow should be further increased. Thus, the position of the two wheels of the depth control 8 can be varied to meet the fullest demand (Figure 3).

For example, if the weight box 21 is to be laterally adjusted to cover or open the vine row so that it does not collide with the vine rows or other plant rows, the retaining screw 20 in the retaining bracket 19 and the retaining bolt 19 in the retaining bolt 40 The retaining bolts 41, 42 must be inserted into the respective holes in the first end of the weight box 21 and the bottom of the weight box 21.

The weight box 21, which provides perfect penetration of the plow into the soil and a constant depth of soil in the soil, ensures that a sufficient amount of soil is evenly distributed to perform these tasks perfectly. (Figure 3).

Depending on the vertical adjustment of the two wheels 8 and the eagle roller 34, the appropriate working depth of the roller beds can thus be controlled.

The steering rollers 24 and 25, for example, are built on a low cost bulk plastic tube 59 by forming a bearing housing 57 which is easy to form at both ends of the tube 59, such as polyamide, methamide, or other plastic and powder metallic plain bearings. sealing ring 62, and dust sealing ring 62, by securing said insert 63 to the plastic tube 59 and bearing 61 located at both ends thereof by means of a dust ring 62 and a nut 56 located at the ends of shaft 58 through a plastic plate 63. A prefabricated self-cleaning, wear-resistant layer 60 corresponding to its diameter and length is then applied to the plastic tube 58. The complete set of castor rollers thus formed with its shaft end 58 placed in the opposite holes of the lower bracket 22 of the castor roller bracket and the upper bracket of the roller bracket 23 holding the castor roller 58; The studs must be fastened to these brackets with 55 washers and 26 nuts (Figure 4/4, Figure 5).

By way of example, the eagle roller 34 is also based on hollow or hollow or solid wheel-shaped plastic. The round metal or plastic plate 48 is fastened to the nut 51 by four equally spaced screws 51 passing through the body of the plastic wheel 80. The metal washer 47 mounted on the lower end of the shaft 45 is clamped in a groove on the lower end pin of the shaft or bolted into a through hole 46 passing through the shaft end to prevent the 45 from moving out of the plastic wheel 80.

In contrast, the dust closure 53 is connected to the upper sealing plate 52 of the echinoder roller 34 to provide dust removal. For mounting around the dust cap 53 and the nut spacer 54 at the shaft end 45, a plate 33 is provided for holding the roller 34 and for holding the roller 27 mounted on the shaft 27 28. An elastic self-cleaning abrasion-resistant microporous rubber or polyethylene sole 49 is secured between the lower and upper upper flaps 48 of the ecumen roller 34.

The vertical position 27 and 28 of the plow blade 1 and the roller blade 34 can be adjusted on the stem 31 by a right and left-hand threaded padlock to control the angular position of the hidden chisel 5 and thus the tiller 6 towards the towing direction. In this way, the plow penetration into the soil can be increased or decreased, so that the angle of the coulter 5 and the plow 6 can be adjusted to an optimum value depending on the condition and quality of the soil to be cultivated.

By using known steering rollers in place of the tiller roller in the roller beds of the present invention, a traction saving of at least 3 to 5% can be achieved compared to similar tiller plows. In addition, during plowing or other operations, the roller bed of the present invention rolls on the depth control wheels 8 and the echinoder roller 34, so that it does not slip on either the plow or the roller bed. This reduces the need for traction energy. In addition, by using the hidden coulter 5 according to the invention, not only the danger of clogging, thus jamming, was eliminated, but in addition to improving productivity and quality of work, additional traction was achieved.

Experimental results of the small-scale roller bed, which can be towed by the human force according to the invention, show good results in manual towing, for example, in loose structure and medium-hard soils (their specific soil resistance is 20-40 kp / dm ² ). The proposed roller bed design is low in weight, weighs up to 10 kg and is extremely simple and inexpensive to construct. With its application, different cultivation tasks in backyard farms, small gardens or foil tents can be performed universally, even under low-crown trees or between narrow rows of vines or other row crops. The proposed roller bed, due to its relatively light weight and small size, is easily transportable by any means of transport. The proposed roller bed, whether or not powered by man, is also capable of being towed by a garden tractor or horse.
