Description

High-pressure hydraulic excavator with mud discharging function

The invention relates to a high-pressure hydraulic excavation device with a mud discharging function.

Patent No. I581699 of the Republic of China discloses an impact type high-pressure hydraulic excavation device that forms columnar holes in the soil where trees grow. The previous case has explained in detail why the soil needs to excavate columnar holes in order to improve the soil environment. Provide large soil particle pores, continuous soil gaps, and deep effective pores, so that the root system of the tree can grow in an environment with good oxygen content and moisture content, so that the tree can grow. The case also cited a number of prior techniques, which explained that the prior techniques used soil pressure, mechanical, and hydraulic methods to improve soil. However, there are some shortcomings that need to be improved.

The aforementioned patent No. I581699 of the Republic of China, in addition to nozzles and nozzles, has the main technical features of an impact head, using the impact part of the front end of the impact head to impact the soil, and the use of the exit hole in the center of the impact head to shoot out powerful Water jets impinge the soil, thereby forming a columnar hole that can reach the hard layer of the soil. Although the technology in this case can achieve the purpose of digging a columnar hole, during the excavation process, because the water has been sprayed into the columnar hole without being discharged, it will be in this column after more water accumulates. The bottom of the pore-like hole is mixed with the rushed mud and sand to form muddy water. If the mud and sand contained in the muddy water is too much or the concentration is too high, it will hinder the powerful water jet to reduce its impulse and affect the efficiency of excavation. If this muddy water can be discharged, the efficiency of hole excavation will undoubtedly be improved.

The currently known mud drainage technology mainly uses a mud drainage device to pump mud water out of the hole. However, it must be separated from the excavation action, that is, the excavation and mud drainage actions are performed separately. , It will become excavation with excavation equipment first. When you want to pump water, take out the excavation equipment and put it into the pumping equipment to pump. After pumping, you must take out the pumping equipment and put it into the excavation equipment to continue digging. This is really troublesome and inconvenient.

The main object of the present invention is to provide a high-pressure hydraulic excavation device with a mud discharging function, which can discharge mud water in a hole to the outside when digging soil.

The impulse softens. If the soil on the wall surface of the hole 91 collapses due to the impulse softening, the excavated hole 91 will not appear columnar, but the upper and lower holes 91 will appear. Therefore, if it is considered that the holes 91 are not to be made larger and smaller, you can choose not to dig the holes 91 too deep, or choose to dig shallow holes 91.

In the first embodiment, in the above-mentioned structure of the shower head unit 11, the crushing portion 111 is tapered. However, as shown in FIG. 6, the crushing portion 111A may be cylindrical.

As for the beneficial effects of the excavated columnar hole 91 on the tree and the time it can maintain, please refer to the description of the invention of the patent No. I581699, which will not be repeated here.

In addition, in the above-mentioned structure of the head unit 11, the connection hole 12 is located at the upper part of the head unit 11. However, the position of the connection hole 12 is not limited to the upper part of the shower head unit 11. As shown in FIG. 8, the connection hole 12C may also be provided on the side of the shower head unit 11C, and the water can be sent to the water channel 13C in the shower head unit 11C. Effect.

As shown in FIG. 9, the water spray direction of the two upper water outlets 16D can also be achieved obliquely. The effect of taking muddy water out of the hole 91 (shown in Figs. 4 to 5).

It can be known from the above that the first embodiment combines the impact excavation device and the mud suction device on a spray head, which can simultaneously achieve hydraulic excavation of soil and removal of silt in a small hole space, which greatly improves the disadvantages of the prior art.

In addition, the prior art must use hydraulic excavation and dredging operations alternately, and the present invention can simultaneously operate hydraulic excavation and dredging operations, thereby improving work efficiency.

Please refer to FIG. 10 again. The high-pressure hydraulic excavation device 30 with mud discharging function described in the second preferred embodiment of the present invention is mainly similar to the first embodiment disclosed above, except that:

This second embodiment further has a row of mud pipes 51, and maintains a fixed relative spatial relationship with the sprinkler unit 31 by a fixing mechanism 52. The sprinkler unit 31 has only one upper water outlet 36, and the upper water outlet 36 The powerful water jet sprayed out from the bottom of the sludge pipe 51 enters the sludge pipe 51 and erupts upward. In addition, a mud inlet 511 is provided at the bottom of the mud discharge pipe 51 for muddy water to enter.

The aforementioned fixing mechanism 52 can be used in various ways. For example, the fixture shown in FIG. 10 is used as the fixing mechanism 52, and the fixture 52 is provided on the sludge pipe 51 and used to hold the sprinkler unit 31; Or, for example, the embedding relationship shown in FIG. 11 is used as the fixing mechanism 52A, which is mainly to embed a part of the sprinkler unit 31A into the wall of the sludge pipe 51A, and the upper water outlet 36A is located in the sludge pipe 51A; Alternatively, for example, a jig shown in FIG. 12 may be used as the fixing mechanism 52B, provided in the sludge pipe 51B, and clamped in the nozzle 41B. The aforementioned several fixing mechanisms 52, 52A, and 52B can maintain the fixed relative spatial relationship between the sludge discharge pipe 51 and the head unit 31.

There can be various ways for the powerful water jet sprayed from the upper water outlet 36 to enter from the bottom of the sludge pipe 51. For example, in the state shown in FIG. 11, a part of the nozzle unit 31A is embedded in the sludge pipe 51A. Pipe wall, and the upper water outlet 36A is located in the sludge pipe 51A, and the powerful water jet sprayed directly enters the sludge pipe 51A; or, for example, the state shown in FIG. 12 is mainly used for The nozzle unit 31B is located outside the mud discharge pipe 51B, and the powerful water jet sprayed from the upper water outlet 36B enters the mud discharge pipe 51B from the mud inlet 511B; in addition, the state shown in FIG. 10 may also be used, for example The nozzle unit 31 is located at the bottom of the sludge pipe 51 and corresponds to the sludge inlet 511, and part of it is located in the sludge pipe 51, and the upper water outlet 36 is located in the sludge pipe 51. In the foregoing several ways, the powerful water jets sprayed from the upper water outlets 36, 36A, 36B can enter the sludge pipe 51 from the bottom of the sludge pipe 51.

Next, the architecture shown in FIG. 10 is taken as an example to explain the operation manner of the second embodiment. As shown in FIG. 13, since the mud removing pipe 51 is maintained in a fixed relative relationship with the nozzle unit 31 by a fixing mechanism 52, during the process of digging the hole 91, the depth of the hole 91 is increasing. As it gets deeper, the sludge discharge pipe 51 goes into the hole 91 along with the nozzle unit 31. Since the powerful water jet sprayed from the upper water outlet 36 directly enters the sludge pipe 51, and the mud water in the cavity 91 also enters the sludge pipe 51 from the sludge pipe inlet 511, The powerful water jet sprayed into the sludge pipe 51 will drive the mud water in the sludge pipe 51 toward the other end of the sludge pipe 51, and then discharge the sludge pipe 51 to achieve the effect of discharging the mud water out of the hole 91. .

It should be added that if the direction of the strong water jet sprayed from the upper water outlet 36 is parallel to the axial direction of the sludge pipe 51, the best effect of driving muddy water can be achieved. However, if the spraying direction is slightly inclined to the axial direction of the sludge pipe 51, although the effect of driving the muddy water will be slightly affected by the skew of the spraying direction, the muddy water can still be effectively driven from the sludge pipe 51 to Outside drained.

The rest of the structure and the effects that can be achieved in this second embodiment are the same as those in the first embodiment, and will not be described again.

Please refer to FIG. 14 again. The high-pressure hydraulic excavation device 60 with mud discharging function described in the second preferred embodiment of the present invention is mainly similar to the second embodiment disclosed above, except that:

A water outlet 64 is provided on the lower spray head 612, an upper shower head 613 is connected to the manifold 611, and an upper water outlet 66 is provided on the upper spray head 613.

In the third embodiment, the upper water outlet 66 and the lower water outlet 64 are mainly provided on the upper spray head 613 and the lower spray head 612, respectively. This method of separately setting the same can also achieve the powerful water jets spraying downward and upward respectively. effect. Although such a structure uses two nozzles, it is still feasible and covered by the creative spirit of the case. In addition, in some cases, the manufacturer may manufacture the manifold 611 and the nozzle 71 integrally, that is, integrally molded. This will increase the cost, but it is also one of the feasible methods in manufacturing. The technical scope of this case is covered.

In addition, in FIG. 14, the sludge discharge pipe 81 is partially cut away to facilitate inspection of the relevant position of the upper spray head 613.

Since the third embodiment uses the structure of two nozzles, the volume reduction effect of integration into a small nozzle can not be achieved as in the second embodiment, but it can still achieve the hydraulic excavation and mud pumping operations at the same time. effect.

The rest of the structure and the effects that can be achieved in this third embodiment are the same as those in the second embodiment, and will not be described again.
