Description

Mud scraping device

1. Field of the invention

The utility model relates to a mud scraping device, which arranges mud scraping plates in an equidistant way, and leads the mud scraping plates of odd numbers such as 1 st, 3 rd, 5 th and 7 th to be linked as a first mud scraping unit and leads the mud scraping plates of even numbers such as 2 nd, 4 th, 6 th and 8 th to be linked as a second mud scraping unit; when the first sludge scraping unit scrapes sludge forwards, the second sludge scraping unit scrapes sludge backwards at the same time, and the sludge effectively passes through the second sludge scraping unit to move forwards under the action of the two sludge scraping units; when the two mud scraping units complete the set stroke, the second mud scraping unit conducts mud scraping forward and resets, the first mud scraping unit conducts mud shoveling backward at the same time, and at the moment, the mud just passing over the second mud scraping unit effectively passes over the first mud scraping unit and continues to advance under the action of the two mud scraping units; therefore, the mud scraper has the characteristic of continuous mud scraping and advancing.

The arrangement distance of the mud scraping plates of the device is S, the stroke of the first mud scraping unit is L1, the stroke of the second mud scraping unit is L2, the half stroke of the first mud scraping unit is X1, the half stroke of the second mud scraping unit is X2, and the section width of the mud scraping plates is W; therefore, the utility model has the following relations:

if the stroke of the first mud scraping unit is the same as that of the second mud scraping unit, namely, L1 is L2, and X1 is X2;

when the two mud scraping units complete the set stroke, in order to prevent the front and rear mud scraping plates from colliding, an anti-collision clearance K value must be preset between the two adjacent mud scraping plates which are close to each other to serve as a design factor; thus, it is possible to provide

X1+X2+W+K＝S

Since L1 is L2 and X1 is X2, the present invention is not limited thereto

X1+X2+W+K＝L1+W+K＝S

L1 < S and L2 < S

Even if the stroke of the first mud scraping unit is different from that of the second mud scraping unit, namely L1 is not equal to L2, and X1 is not equal to X2;

when the two mud scraping units complete the set stroke, the section width W and the value of the collision avoidance clearance K of the mud scraping plates still cause that:

l1 < S and L2 < S

2. Background of the invention

The principle, action mode and function of the common mud scraping device are as follows:

the device of scraping mud commonly used can be divided into two kinds such as chain formula and reciprocating type, because the chain formula is comparatively expensive in the cost, and the construction difficulty degree is high, and required installation space is also very big, occupies whole pond and equipment almost, and its principle, mode of action and function are all not the utility model discloses a category, so from slightly, only just reciprocating type common device now, the summary is as follows:

the commonly used reciprocating mud scraping method and device, all the arranged mud scraping plates are connected as the same mud scraping unit for linkage, the action mode is as shown in fig. 21 to fig. 25, the mud scraping plates A, B, C, D are connected as the same mud scraping unit 1 for linkage, and all have an inclined plane a, the mud and sand 2 are continuously settled; when the mud scraping unit 1 is not yet activated, the mud scraping plates B, C, D are in the position as shown in fig. 21; when the mud scraping unit 1 starts to move forward, the mud scraping plates B and C move to the position shown in FIG. 22 and scrape the mud 4 deposited on the bottom 3 of the tank; when the mud scraping unit 1 continues to move forwards, the mud scraping plates A, B and C move to the positions shown in FIG. 23 and complete the forward stroke, so that the scraped mud 5 advances to the forward position, and the mud scraping action is finished; when the mud scraping unit 1 starts to return backwards, the mud scraping plates A, B and C move to the position shown in FIG. 24, and the part of the mud 6 which has scraped the mud 5 passes over the mud scraping plates A, B and C along the inclined surface a; when the mud scraping unit 1 continues to reset backwards, the mud scraping plates B, C and D move to the positions shown in FIG. 25 and complete the resetting stroke; the mud scraping and advancing can be achieved by circularly operating the actions shown in fig. 22 to 25.

Since the above conventional apparatus has two major disadvantages, the effect is not ideal and needs to be improved in practical engineering, as shown in fig. 21 to 25, the following disadvantages are: I. in principle and in action, there are drawbacks that already exist and will lead to functional incompleteness:

when the scraper unit 1 is reset, the scrapers a, B, C, D move backward as shown in fig. 24, and the scraped sludge 5 has the function of scraping the sludge while some of the sludge 6 passes over the scrapers a, B, C, D along the inclined plane a, but at the same time: the sludge remaining after the scraped sludge 5 is removed part of the sludge 6 is pushed back to the original position due to the backward movement of the scraping plates A, B, C and D; therefore, the scraping and shoveling of the scrapers a, B, C, D during the reciprocating motion are offset to a certain extent, i.e. when the scrapers a, B, C, D reset to shovel, the sludge that has not passed over the scrapers a, B, C, D in the previous time is pushed back to the original position, so as to reduce the previous scraping effect, and the effect is not ideal. II. In the physical design, the stroke of the mud scraping unit is required to be larger than the arrangement interval of the mud scraping plates, and the required row of the hydraulic cylinder

The process is large:

generally, when the method is implemented in practical engineering, the stroke of the adopted mud scraping unit is about 70cm, the arrangement distance of the mud scraping plates is about 50cm, namely, the mud scraping plate A must move to a position beyond the position before the mud scraping plate B moves, the distance beyond the position is about 20cm, the mud scraping effect can be achieved, otherwise, the mud scraping advancing effect is not good; therefore, in the physical design, the required hydraulic cylinder has a large stroke and a high cost, and in terms of the mechanism design, the large stroke needs to consider increasing the strength of the transmission assembly (due to the long size of each link member) and also needs to consider increasing the rigidity of the transmission assembly (due to the large action amplitude of each link member); moreover, the conventional users are limited by the design that the stroke of the mud scraping unit is required to be larger than the arrangement interval of the mud scraping plates, so that the arrangement number of the mud scraping plates is large, and the arrangement is not ideal.

3. Summary of the invention

The main objective of the present invention is to provide a method for arranging scrapers at equal intervals, and link the single number of scrapers such as 1 st, 3 rd, 5 th, and 7 th scrapers as the first scraper unit, and link the double number of scrapers such as 2 nd, 4 th, 6 th, and 8 th scrapers as the second scraper unit; the two mud scraping units move in opposite directions in a reciprocating manner, so that the mud scraping method and the mud scraping device have the characteristic of continuous mud scraping advancing, and obviously have the following advantages, characteristics, purposes and efficacies: 01. the mud scraping advancing effect is clear: each time the two mud scraping units are actuated, the two mud scraping units simultaneously scrape and shovel mud, and the two mud scraping units are actuated

The combined action can really achieve the effect of mud scraping advancing without the generation of the common offset phenomenon, and the mud scraping effect is not only

Without reduction, each time the scraper is actuated, the scraping and shoveling actions are performed between two scraping units at the same time, so that the scraper is driven to move in a reciprocating manner

The efficiency of mud scraping advancing is far better than that of the common method and device. 02. The device of the utility model has the relational expression that L1 < S and L2 < S, namely the layout space of the mud scraper

S is far larger than the stroke of the first mud scraping unit to be L1, and can also be far larger than the stroke of the second mud scraping unit to be L2;

this relationship clearly has the following advantages and enhancements of efficacy:

a. if the arrangement space S of the mud scraping plates is the common arrangement space and the same arrangement quantity exists, the L is the same

1 < S and L2 < S, the required cylinder stroke must be much less than that of conventional devices, and the machine is ready for use

In view of the design, the smaller stroke not only makes the system more stable, but also the transmission component

The strength and rigidity to be considered are smaller than those in common use, so the cost is greatly reduced.

b. If the stroke L1 of the first scraper unit and the stroke L2 of the second scraper unit are common strokes, the stroke L1 of the first scraper unit and the stroke L2 of the second scraper unit are common strokes

When the hydraulic cylinders with the same stroke are used, the arrangement distance of the mud scraping plates is increased because L1 is less than S and L2 is less than S

S is increased inevitably, the number of the mud scrapers required to be arranged is less than the common number, and the installation is greatly saved

Cost and man-hours.

The utility model discloses a reach foretell purpose and efficiency, the technical means who adopts is:

the method comprises the steps of arranging the mud scrapers at equal intervals, connecting the odd number mud scrapers of 1 st, 3 rd, 5 th, 7 th, and the like as a first mud scraping unit for linkage, and connecting the even number mud scrapers of 2 nd, 4 th, 6 th, 8 th, and the like as a second mud scraping unit for linkage; the layout space S of the mud scraping plates, the stroke L1 of the first mud scraping unit and the stroke L2 of the second mud scraping unit have the relational expressions that L1 is less than S and L2 is less than S; the two mud scraping units move in a reciprocating way in opposite directions, and have the characteristic of continuous mud scraping advancing; while

The device at least comprises a first mud scraping unit, a second mud scraping unit, a transmission unit and the like; wherein:

the first mud scraping unit is provided with odd mud scraping plates such as 1 st, 3 rd, 5 th and 7 th mud scraping plates, and is linked with the first transmission rod into a same unit through a first fixing component;
