Description

Technical Field

[0001] The utility model relates to an electric scraper, in particular to an impact electric scraper. Background Art

[0002] When a building wall is renovated, it is necessary to scrape off the original wall coating, such as putty powder, latex paint, lime sand layer, etc., and generally a scraper is needed to scrape off the wall coating. The current scraper generally consists of a blade and a handle.

[0003] At present, there are scrapers that are manually pushed to remove the wall coating, such as the wall scraper disclosed in patent CN208122362U, which includes a handle, one end of the handle is threadedly connected to a knife seat, and a blade is arranged on the knife seat. The blade is detachably fixed to the knife seat, and the blade edge extends out of the end of the knife seat. When in use, the user holds the handle and pushes it back and forth, so that the handle drives the blade head to move back and forth to remove the coating on the wall. However, a manual scraper needs to be pushed hard to remove the coating. Pushing the scraper for a long time will easily fatigue the arm and other parts, and the efficiency is low.

[0004] In order to solve the problem of manual scrapers, electric scrapers have appeared on the market, which use electric means to drive the scraper to move back and forth to perform wall scraping operations. For example, the patent CN219033910U discloses a wall scraper, including a motor, a casing, a transmission rod, a cylindrical cam and a scraper. The motor includes a casing and a shaft. The casing is fixedly arranged on the casing, the transmission rod is rotatably arranged in the casing and is transmission-connected to the shaft, the cylindrical cam is rotationally arranged in the casing and is also transmission-connected to the transmission rod, the scraper is slidably arranged on the casing, and an elastic member is arranged on the casing. The elastic member is used to force the scraper to abut against the cylindrical cam. The cylindrical cam includes at least two inclined portions, and the two or more inclined portions are evenly arranged on the end surface of the cylindrical cam. When the cylindrical cam rotates and the scraper moves from the lower end of the inclined portion to the higher end, the cylindrical cam pushes the scraper forward. When the cylindrical cam rotates to a position where the scraper is opposite to the lower end of another inclined portion, the spring member drives the scraper to move back to its position to realize the reciprocating linear motion of the scraper.

[0005] The scraper head of the existing electric scraper is pushed by a cylindrical cam to achieve reciprocating linear motion to scrape the surface of an object. This type of scraper can meet the needs of general wall skin or the removal of pollutants adhering to the wall, the ground and other surfaces of objects. However, when encountering wall skin that is tightly adhered or has strong adhesion, it is difficult for the existing electric scraper to scrape off the wall skin with strong adhesion. Sometimes it needs to cooperate with workers to knock to achieve scraping, which has the problems of laborious cleaning operation and low work efficiency. Utility Model Content

The impact assembly can be slidably arranged between the striking system 33 and the mounting portion 2. The striking system 33 includes a rotating member 11, and the rotating member 11 is driven to rotate by the power provided by the motor 9. A striking portion 12 is provided on the rotating member 11. The striking portion 12 on the rotating member 11 can strike the impact assembly when the rotating member 11 rotates, so that the impact assembly strikes the scraper functional head 8 mounted on the mounting portion 2, and the scraper functional head 8 performs a linear impact motion forward and backward.

[0032] The impact of the scraper functional head 8 enables the scraper functional head 8 to scrape off the tightly adhered wall skin or pollutants adhered to the wall surface, the ground and other object surfaces, thereby improving work efficiency.

[0033] Figure 2 , Figure 3 As shown, preferably, the rotating member 11 is disc-shaped, and at least one extending striking portion 12 is provided on the circumferential side wall of the rotating member 11, and the striking portion 12 on the rotating member 11 intermittently strikes the impact assembly when the rotating member 11 rotates. Preferably, there are two striking portions 12, and the two striking portions 12 are evenly arranged on the circumferential side wall of the rotating member 11, so that the rotating member 11 can strike the impact assembly twice through the two striking portions 12 when the rotating member 11 rotates one circle, that is, when the rotating member 11 rotates one circle, the scraper functional head 8 intermittently performs two forward and backward linear impact movements.

[0034] The rotating member 11 may be directly driven by the motor 9 , or the rotating member 11 may be indirectly driven by the motor 9 .

[0035] Preferably, the motor shaft axis of the motor 9 is perpendicular to the rotation centerline of the rotating member 11 , and a transmission assembly for transmitting power is provided between the motor 9 and the rotating member 11 .

[0036] Figure 6-Figure 8 As shown, preferably, the striking system 33 includes a transmission assembly and a housing 10, and the transmission assembly and the rotating member 11 are integrated and installed in the housing 10. The transmission assembly transmits the power provided by the motor 9 to the rotating member 11 to drive the rotating member 11 to rotate. The transmission assembly and the rotating member 11 are integrated in the housing 10 so that the entire striking system 33 is combined into an independent whole. During installation, only the entire housing 10 needs to be installed in the casing 1, which is convenient for the installation of the striking system 33.

[0037] Preferably, the transmission assembly includes a first shaft 53 and a second shaft 50 rotatably arranged in the housing 10, the first shaft 53 is perpendicular to the second shaft 50, and the first shaft 53 is parallel to the motor shaft of the motor 9, a driving gear 55 is fixed on the motor shaft, a first bevel gear 52 and a driven gear 54 meshing with the driving gear 55 are fixed on the first shaft 53, a second bevel gear 51 meshing with the first bevel gear 52 is fixed on the second shaft 50, and the rotating member 11 is fixed on the second shaft 50, when the motor 9 is started, the driving gear 55 rotates and drives the driven gear 54 to rotate, the first shaft 53 and the first bevel gear 52 rotate coaxially with the driven gear 54, the first bevel gear 52 drives the second bevel gear 51 to rotate, so that the second shaft 50 and the rotating member 11 rotate coaxially, thereby realizing the rotation of the rotating member 11, and the rotation center line of the rotating member 11 is perpendicular to the motor shaft.

[0038] The first shaft 53 and the second shaft 50 are supported in the housing 10 via bearings.

[0039] The box body 10 is divided into an upper shell 48 and a lower shell 49. The upper shell 48 and the lower shell 49 are fixed by screws after being matched, so as to facilitate the assembly of internal parts.

[0040] The input end of the housing 10 has an input head 47, which has an input port for inserting the motor shaft of the power supply machine 9. The motor shaft with a driving gear 55 extends from the input port into the housing 10 and is connected to the transmission assembly.

[0041] Preferably, since the axis line of the motor shaft of the motor 9 is perpendicular to the rotation center line of the rotating part 11, the motor 9 can be arranged behind the striking system 33, and the motor 9, the striking system 33, the impact assembly and the mounting part 2 are arranged in sequence from back to front. The casing 1 is a shell for supporting the motor 9, the striking system 33 and the impact assembly, so that the casing 1 as a whole can be arranged into a structure similar to a long rod, and the mounting part 2 is arranged at the front end opening of the casing 1.

[0042] Preferably, the mounting portion 2 is a chuck for clamping the scraper functional head 8, and the structure of the chuck is the same as that of existing electric tools.

[0043] Figure 3As shown, for example, the chuck includes a blade sleeve 25 fixed in the housing 1 and partially extending from the front end opening of the housing 1. The blade sleeve 25 is provided with a clamping hole 24 for inserting the shovel rod of the blade functional head 8. The clamping hole 24 extends along the axial direction of the blade sleeve 25 and passes through both ends of the blade sleeve 25. The outer side of the blade sleeve 25 is sleeved with a locking sleeve 16. The locking sleeve 16 is sleeved on the outer side of the blade sleeve 25 and can slide forward and backward along the blade sleeve 25 to lock the blade sleeve 25 in the locked position. The blade sleeve 25 is switched between the locked and unlocked positions. The side wall of the blade sleeve 25 is provided with a plurality of accommodating holes 22 connected with the clamping hole 24. Steel balls 23 are placed in the accommodating holes 22. The shovel rod of the blade functional head 8 is provided with a card slot 21 corresponding to the accommodating holes 22. The card slot 21 has an extended length for the steel ball 23 to move back and forth relative to the shovel rod of the blade functional head 8, so that the blade functional head 8 can slide linearly back and forth relative to the mounting portion 2 when installed in the clamping hole 24.

[0044] The locking sleeve 16 has an escape space 19 for the steel ball 23 to move outward, and a blocking portion 18 to block the steel ball 23 from moving outward. When the locking sleeve 16 moves to an unlocking position relative to the scraper sleeve 25, the escape space 19 moves to a position opposite to the steel ball 23. At this time, the shovel rod of the scraper functional head 8 can be inserted into the clamping hole 24, so that the steel ball 23 is clamped into the slot 21 on the shovel rod; when the locking sleeve 16 moves to a locking position relative to the scraper sleeve 25, the blocking portion 18 moves to a position opposite to the steel ball 23, blocking the steel ball 23 from escaping from the slot 21, thereby completing the installation of the scraper functional head 8.

[0045] The receiving hole 22 is a circular hole, and the inner opening diameter of the receiving hole 22 connecting with the clamping hole 24 is smaller than the diameter of the steel ball 23 to prevent the steel ball 23 from completely falling into the clamping hole 24 after the shovel rod is pulled out of the clamping hole 24 .

[0046] A return spring 17 is provided between the lock sleeve 16 and the casing 1 to keep the lock sleeve 16 in the locked position. The return spring 17 is sleeved on the outside of the scraper sleeve 25, and one end of the return spring 17 is against the lock sleeve 16, and the other end of the return spring 17 is against the casing 1. A retaining spring 20 is clamped at the front end of the lock sleeve 16. The elastic force of the return spring 17 pushes the lock sleeve 16 to move forward relative to the scraper sleeve 25, and presses the lock sleeve 16 against the retaining spring 20, so that the lock sleeve 16 is in the locked position.

[0047] Figure 3 , Figure 7 , Figure 8 As shown, preferably, the impact assembly includes an impact shaft 15 and an impact pin 28 located in front of the impact shaft 15. The impact shaft 15 and the impact pin 28 can be slidably arranged in the casing 1 forward and backward. The impact shaft 15 is struck by the striking part 12 to make a forward and backward linear motion. After the impact pin 28 is impacted by the rear impact shaft 15, it can hit the scraper functional head 8 installed on the mounting part 2.

[0048] Specifically, the rear end of the blade sleeve 25 is provided with an assembly groove, which is located behind the clamping hole 24 and is connected to the clamping hole 24. A receiving member is installed in the assembly groove, and the rear side of the receiving member is limited by a retaining spring 20 that is clamped on the inner wall of the receiving groove. A receiving cavity 30 is provided in the receiving member for accommodating the impactor 28. The impactor 28 is accommodated in the receiving cavity 30. The front and rear sides of the receiving member have cavity openings for the front and rear ends of the impactor 28 to extend out. The impactor 28 is provided with an outer ring edge 26, and the size of the outer ring edge 26 is larger than the cavity openings on the front and rear sides. , so that the impactor 28 is limited in the accommodating chamber 30 and can slide back and forth, the front end of the impactor 28 is opposite to the scraper functional head 8 assembled in the clamping hole 24, and the rear end of the impactor 28 is opposite to the front end of the impact shaft 15. The output end on the front side of the box body 10 is provided with an output head 13, and the output head 13 has an output hole 14 for partial insertion of the impact shaft 15. The output hole 14 is connected to the inside of the box body 10, and the impact shaft 15 is partially inserted in the output hole 14 so as to be slidable back and forth, and the rear end of the impact shaft 15 extends into the box body 10 for the striking part 12 to strike.

[0049] The accommodating member includes a front limiting sleeve 27 and a rear limiting sleeve 29 , and the front limiting sleeve 27 and the rear limiting sleeve 29 are matched to form the above-mentioned accommodating cavity 30 therebetween.

[0050] Working principle: install the scraper function head 8 in the clamping hole 24, start the motor 9, and the motor 9 drives the rotating part 11 to rotate in the box 10 through the transmission assembly. During the rotation of the rotating part 11, the striking part 12 strikes the rear end of the impact shaft 15, so that the impact shaft 15 strikes forward on the impact pin 28. After the impact pin 28 bears the impact of the rear impact shaft 15, it hits the scraper function head 8 installed on the mounting part 2 forward, so that the scraper function head 8 moves forward to scrape the wall skin on the wall surface. After the forward movement is completed, the scraper function head 8 rests on the wall and moves backward under the action of the operator's front push, so that the scraper function head 8, the impact pin 28 and the impact shaft 15 can all achieve backward reset to prepare for the next impact. The rotating part 11 rotates continuously so that the striking part 12 on the rotating part 11 intermittently strikes the impact shaft 15 to achieve intermittent reciprocating impact operation of the scraper function head 8.
