Detailed Description
First embodiment: the underground film lining machine for the sand paddy field, which is exemplified in fig. 1 and 2, is provided with a pair of frames 1 which can be pulled by a tractor, wherein the frames 1 are provided with a shovel blade 2, the shovel blade 2 is rectangular plate-shaped, the front part of the shovel blade 2 is arranged on the frames 1 in a low-back high-inclination manner, a plastic film roll 4 is arranged below the rear side of the shovel blade 2, and a plastic film roll 5 can be arranged on the frames through a rotating shaft.
As can be seen in fig. 3 and 4, the front of the blade 2 is very low, the rear part is higher below the frame 1, and the surface of the blade is preferably streamline, and the left side and the right side are provided with protruding frames 6.
The inclination angle of the shovel blade 2 is determined according to the buried depth of the underground plastic film. Typically, the minimum depth is 200mm to accommodate root growth of rice. Considering that a field may have a large weight of tools passing through, the depth of the underground plastic film should be preferably 400-500 mm. If the subsurface depth is fixed, the size and angle of inclination of the blade may also be fixed. Considering that the depth of the underground lining film does not form a unified standard, the practice of each production unit can be different, so that the inclination angle of the shovel blade can be adjusted preferably. The figure illustrates a simplest depth-adjusting structure: the middle part of the lower side of the shovel blade is provided with a supporting shaft 5, two ends of the supporting shaft 6 are inserted into shaft holes below two sides of the frame, and the shovel blade can swing around the supporting shaft 5. The rear part of the upper part of the frame relative to the shovel blade is provided with an angle adjusting bolt 3, the angle adjusting bolt 3 is vertically arranged in a screw tube of the frame, the lower end of the angle adjusting bolt is opposite to the surface of the shovel blade, and the upper end of the angle adjusting bolt is provided with a handle. The handle is pulled to change the height of the lower end of the angle adjusting bolt 3, so that the inclination angle of the shovel blade can be changed, namely the depth of the shovel blade entering the soil is changed.
When the sand is used, as shown in fig. 5, the sand is properly leveled firstly, a trench is dug on the ground head by the frame 1, a scraper knife is inserted into the lower bottom of the trench, one end of the plastic film is pulled out manually and paved on the bottom surface of the trench, then the machine is started and goes forward, sand is supported by the scraper knife in the forward process, limited by the side frames 7 at the two sides, can only slide backwards, and slides across the scraper knife and falls on the underlying lining film.
In addition, the frame 6 at the rear side of the scraper knife is preferably inclined inwards, sand pressed on the plastic film can be concentrated in the middle of the plastic film, and a space is reserved on two sides of the frame so as to be mutually overlapped with the adjacent plastic film, and then the frame is naturally leveled or a scraper blade is arranged behind the frame for scraping. In order to prevent resistance caused by the inward inclination of the frame, the inclined section can be arranged behind the highest position of the shovel blade.
Second embodiment: the improvement over the first embodiment is mainly to change the shape of the blade. As shown in fig. 6, a plurality of tines 7 are provided at the front end of the blade. The sharp teeth are triangular, the sharp corners are forward, and the two sides of the sharp teeth are sharp inclined planes. Compared with the rectangular shovel blade of the first embodiment, the sharp teeth 7 have better cutting performance and can cut off sundries such as grass and tree roots and the like in the sand. Generally, the flowing sand dunes are relatively pure, the cutting resistance is not large, and a shovel blade with a neat head can be used. However, for some fixed dunes, plants such as the plants of the Artemisia annua grow at one time, a plurality of sundries are mixed in the plants, and the operation of the shovel blades with the same head is difficult. The inclined plane of the sharp-tooth shovel blade can move relative to sundries in the advancing process, so that the sundries are subjected to friction cutting, and the operation performance is greatly improved.
Third embodiment: the improvement over the second embodiment is mainly to change the shape of the cutting edge 7. As shown in fig. 6, a plurality of tines 7 are provided at the front end of the blade. Between the two tines there is one half-tine 8. The half sharp teeth 8 are also triangular, the sharp corners are forward, and the two sides are sharp inclined planes. In contrast, the ends of the two side edges of the half tines are not directly connected to the side edges of the tines, but rather are opposite the middle of the tines, narrowing in rear width, and finally meeting the ends of the tines, i.e., the side edge ends of the tines pass the side edge ends of the half tines.
The improvement is mainly to prevent sundries from accumulating on the roots of the original tines. The side edge of the tine has good cutting performance, but the debris opposite the root of the tine does not directly touch the root of the tine with the side edge cut, the shear is entirely positive pressure shear, and there is little sliding cut. Therefore, impurities with higher strength can be accumulated at the root parts of the sharp teeth, and cause barriers to the forward movement of the shovel blade.
According to the novel double-pointed-tooth cutting machine, the half-pointed tooth is additionally arranged between the two pointed teeth, the tail end of the side edge of the half-pointed tooth is opposite to the middle of the side edge of the pointed tooth and passes through the tail end of the pointed tooth, so that all sundries in front of the pointed tooth and the half-pointed tooth can slide relatively to the side edge, the dead angle of cutting at the root of the original pointed tooth is eliminated, and the cutting performance is remarkably improved.
Fourth embodiment: on the basis of the foregoing embodiments, the conveying performance of the blade is improved. The resistance is great because of the sand with 400-500 mm of one-time shoveling. For a flowing sand dune with good fluidity, the shoveled sand can smoothly roll over the shovel blade under the pushing of the sand in front and fall on the rear plastic film. However, for sand dunes with poor flowability, the above process may be hindered. In order to solve the problem, in this example, a throwing roller 9 is additionally arranged on the shovel blade, a rotating shaft is arranged in the middle of the throwing roller, and a plurality of blades 10 are uniformly distributed on the periphery of the throwing roller. The blade 10 is a rectangular steel plate with a slight curvature at the front. During operation, the rotating shaft is driven by the power machine to rotate, and the blade 10 can throw sand to the rear. Meanwhile, the blade 10 has stronger sand digging performance, so that the cutting resistance of the shovel blade can be greatly reduced, and the whole operation process is smoother.
Fifth embodiment: the structure of the throwing roller and the blade is improved on the basis of the fourth embodiment. The blade of the fourth embodiment may lift a portion of the sand and soil when it is rotated under the throwing roller, and it is desirable to have some change in the angle of the blade at this position, which angle swings at an angle opposite the direction of rotation, to enhance throwing performance and avoid or mitigate entrainment. For this purpose, the structure shown in fig. 10 is employed in this example. The throwing roller 9 is seen to have two steel rings, an outer ring 11 and an inner ring 12, which is smaller in diameter than the outer ring and which is placed inside the outer ring, preferably in a plane. The outer ring and the inner ring are not concentric, and are driven by two rotating shafts to rotate at equal rotation numbers respectively. As can be seen in connection with fig. 11, 12: a plurality of pin shafts 13 are uniformly distributed on the outer ring. As can be seen in connection with fig. 13, 14: a plurality of groups of clamping shafts 14 are uniformly distributed on the inner ring 12, and each group comprises two clamping shafts. As can be seen in connection with fig. 15: the blade 10 is provided with a shaft hole 15, and the shaft hole 15 is matched with the pin shaft 13 on the outer ring. The tail section of the blade 10 is a bent shank 16, the shank 16 being slidable between two clamping shafts 14 of the inner ring.
Obviously, each blade 10 is mounted on the pin through a shaft hole and can swing around the pin, and the handle of the blade reciprocates in the two pins of the inner ring, thereby determining the working position of the blade. The distance between the edges of the two rings varies everywhere due to the non-concentricity of the inner and outer rings. One of the two sections is very close, the other section is very far, and the change between the far and the near is excessive. At a shorter distance, the clamping shaft is positioned in front of the tool shank, and at a longer distance, the clamping shaft moves backward relative to the tool shank. Because of the bending angle between the knife handle and the blade, the backward moving clamping shaft can force the angle of the blade to change. When the clamping shaft is positioned at the tail part of the cutter handle, the reverse swing angle of the cutter blade is maximum, the throwing performance is best, and the clamping problem is minimum. According to the structure principle, the position with the best throwing performance is opposite to the conveyor belt, so that the best sand digging and conveying effects can be obtained.
Sixth embodiment: the shape of the throwing roller blade is modified on the basis of the fourth or fifth embodiment. As shown in fig. 16 and 17, the blade 10 of the throwing roller 9 is composed of a plurality of spike teeth, and the outer ends of the spike teeth are bent along the throwing wheel axial direction. The positions of the teeth of two adjacent rows are staggered. Obviously, the spike-shaped blade has better cutting performance, can disperse and throw a large amount of sand and is particularly suitable for lining film operation of sand dunes with larger viscosity.
Seventh embodiment: modifications are made on the basis of the foregoing embodiments. As shown in fig. 18 and 19, an auger 17 is attached to the upper surface of the blade 3. Auger 17 is a drill body device formed by installing a spiral plate around the periphery of the auger shaft. The auger 17 is shown as a plurality of rods, and is mounted in the fore-and-aft direction of the machine tool operation, with the front end being the point of the drill reaching the front of the blade, and the rear end being mounted on a beam above the frame and being entrained for rotation by the power machine. During operation, the auger 11 rotates to excavate sand and soil in cooperation with the shovel blade, and pushes the sand and soil to the rear of the shovel blade, so that the cutting resistance of the shovel blade can be greatly reduced, and the whole operation process is smoother.
Eighth embodiment: the shape and mounting position of the blade are modified on the basis of the previous embodiments. As shown in fig. 20, the blade has a flat plate shape, has a small inclination angle, and is integrally installed below the frame. The shovel blade 3 is characterized in that the whole shovel blade walks under the sandy soil layer. Obviously, the flatter the blade, the less resistance to cutting. However, in order to install the plastic film roll 4 under the shovel blade, the shovel blade still needs to have a certain inclination angle. In order to reduce the inclination angle of the shovel blade 3, a special-shaped plastic film roll 4 is arranged below the shovel blade 3. As can be seen from fig. 21, the special-shaped plastic film roll 4 has a front roll and a rear roll, the front roll 18 is thinner, the rear roll 19 is thicker, and the front roll 18 and the rear roll 19 are supported by a supporting arm 20, so that a plate-shaped plastic film roll with thick ends and thin ends is formed. Obviously, the thickness of the plastic film roll is greatly reduced compared with the diameter of the cylindrical plastic film roll, the required installation space is small, and the inclination angle of the shovel blade is reduced.
As shown in fig. 22, the underground film lining machine for the sand paddy field is hung behind a tractor, a scraper knife moves under a sand layer, the film lining operation can be completed without lifting sand above a frame, the cutting resistance and the conveying energy consumption are greatly reduced, and good effects are achieved in experiments of various sand types.
