Description

Technical Field

[0001] The invention relates to the technical field of trowel machine structures, in particular to a trowel machine for ground finishing. Background Art

[0002] A trowel is a tool for roughing and finishing concrete surfaces, significantly improving their compactness and wear resistance. Its main structure consists of a gasoline engine-driven trowel rotor with a trowel attached to the base of the cross in the middle of the rotor. The trowel's tilt aligns with the rotor's rotation, and the gasoline engine drives a V-belt to rotate the trowel rotor.

[0003] A trowel machine with publication number CN107190958A includes a chassis, a driver's seat, an engine, a smearing mechanism, and a transmission mechanism. The rotation axis of the mounting seat is arranged perpendicular to the line connecting the two mounting seats. The chassis is hinged with a straight-moving cylinder corresponding one-to-one with a rocker arm. The driver's seat is provided with an operating handle corresponding one-to-one with the straight-moving cylinder. The chassis is provided with a hydraulic oil tank connected to the straight-moving cylinder. The operating handle controls the oil inlet or outlet of the straight-moving cylinder.

[0004] The trowel machine uses a trowel to trim the concrete floor. During the trimming process, the uneven raised parts of the concrete will be removed to form debris (especially when the concrete is just poured and the flatness is trimmed, some debris will be removed). However, the trowel on the existing trowel machine is not equipped with a collection mechanism and cannot be collected in time, causing the debris to move with the trowel, affecting the finishing flatness.

[0005] For this purpose, we propose a trowel for ground finishing. Summary of the Invention

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figures 1-17 The present invention provides a trowel for floor finishing, comprising a chassis 1 and a driving member, wherein a plurality of mounting discs 2 are fixedly connected to the output shaft of the driving member, and a trowel 3 is mounted on the mounting disc 2; It also includes a switching member, a limiting member, an obliquely distributed plug-in plate 4, and a collecting plate 5 that is plugged into the mounting plate 2. The collecting plate 5 is slidably fitted with a switching plate 6. The switching plate 6 is controlled by a switching member to have multiple diverter plates 7. The lengths of the multiple diverter plates 7 are arranged in a decreasing manner and are pressed against the collecting plate 5. The ends of the diverter plates 7 are rotatably connected to guide plates 8. Connectors are provided between the multiple guide plates 8. A slider 9 is connected between two adjacent switching plates 6. The slider 9 is slidably adjusted with the smear 3 through the limiting member. The plug-in plate 4 is plugged into and fitted with the collecting plate 5 and the switching plate 6 at the same time. The collecting plate 5 is fixedly mounted on the smear 3 by the limiting member, and the position of the switching member is adjusted so that the multiple diverter plates 7 are fixed on the collecting plate 5 at the same time and will not rotate along the collecting plate 5. The driving member is started to make the smear 3 move in a circular motion to trim the poured concrete pavement. During the trimming process, the concrete debris moves along the smear 3 under the action of centrifugation and is thrown out. The debris passes through the diverter plates 7 and is collected step by step at multiple lengths in a decreasing distribution. That is, the debris first enters a part of the diverter plates 7 close to the position of the connecting plate 18, and the remaining debris enters the diverter plates 7 gradually away from the position of the connecting plate 18. The debris is collected in an orderly and graded manner to ensure the collection effect. After the collection is completed, the smearing work is stopped, the smear 3 stops moving, and the connection between the slider 9 and the fixed plate 24 is released to separate the fixed plate 24 and the diverter plate 7 from the smear 3. Then the movable switching plate 6 is activated, and the diverter plate 7 is rotated on the collecting plate 5 under the action of the switching member, so as to facilitate the cleaning of the debris on the diverter plate 7 and timely remove the debris on the smear 3 (corresponding to the positions of the collecting plate 5 and the diverter plate 7).

[0019] The switching member includes a rectangular block 10 and a plug rod 11. The rectangular block 10 is connected and fixed to the plug rod 11. The switching plate 6 is fixedly connected to a connecting plate 12 connected and fixed to the rectangular block 10. The collecting plate 5 is provided with a sliding groove 13 that slides with the connecting plate 12. The diverter plate 7 is provided with a circular groove 14 and a rectangular groove 15. The rectangular block 10 is plugged into the rectangular groove 15, and the plug rod 11 is plugged into the circular groove 14. When the collecting plate 5 is inserted into the connecting plate 18, the switching plate 6 is activated, so that the switching plate 6 moves along the collecting plate 5, so that the rectangular plate is inserted into the rectangular groove 15, so that the diverter plate 7 is fixed on the collecting plate 5, and the slider 9 is fixed to the fixed plate 24 and the smear 3 through the plug-in plate 23. The smear 3 moves in a circular motion, and the debris enters the space between the collecting plate 5 and the diverter plate 7, and between two adjacent diverter plates 7 in turn, completing the collection; When the collection is completed, the smear 3 stops rotating, and by removing the plug-in plate 23, the slider 9 is separated from the fixed plate 24, and the collecting plate 5 is separated from the connecting plate 18, thereby cleaning the collected debris, and through the switching piece, the diverter plate 7 is rotated along the collecting plate 5, so as to facilitate cleaning the debris between the collecting plate 5 and the diverter plate 7, and between two adjacent diverter plates 7.

[0020] A plurality of elastic plates 16 distributed in an inclined manner are fixedly connected to the diverter plate 7 , and two corresponding elastic plates 16 are cross-distributed. A blocking plate 17 is fixedly connected to the diverter plate 7 .

[0021] One of the elastic plates 16 is pressed against the guide plate 8, and the inclined elastic plate 16 limits the inclination direction of the guide plate 8, so that the movable guide plate 8 can guide the debris on the smear 3 into the space between the collecting plate 5 and the diverter plate 7, and between two adjacent diverter plates 7, and prevent the debris from entering the rectangular rod, the plug rod 11, the rectangular groove 15 and the circular groove 14 through the blocking plate 17; The two corresponding elastic plates 16 effectively prevent the debris that has entered between the collecting plate 5 and the diverter plate 7 and between two adjacent diverter plates 7 from being reset and released (preventing the debris from being reset toward the mounting plate 2 ).

[0022] A connecting plate 18 is fixedly connected to the middle part of the smear 3, and a plug-in groove 19 is provided on the connecting plate 18. The collecting plate 5 is an L-shaped structure. The collecting plate 5 and the diverter plate 7 are jointly provided with a baffle 20. The collecting plate 5 is fixedly connected to the limiting plate 21, and the collecting plate 5 and the limiting plate 21 are slidably matched with the plug-in groove 19 at the same time. The wire plate and the collecting plate 5 are inserted into the plug-in groove 19 at the same time, thereby ensuring that the collecting plate 5 and the diverter plate 7 are fixed on the connecting plate 18. At the same time, the plug-in plate 23 is plugged into the fixed slider 9 and the fixed plate 24 through the limiting member. On the one hand, the switching of the switching member is guaranteed, so that the rectangular rod is plugged and fixed to the rectangular groove 15, and the diverter plate 7 will not rotate on the collecting plate 5. On the other hand, it is ensured that the collecting plate 5 and the diverter plate 7 are stably fixed on the connecting plate 18 and the smear 3. The switch plate 6 is provided with two grooves 22. The plug-in plate 4 passes through the limiting plate 21 and is inserted into the collecting plate 5 and plugged into the grooves 22. The bottom of the plug-in plate 4 is made of a high-density magnetic material. The bottom end of the plug-in plate 4 magnetically cooperates with the grooves 22. The plug-in plate 4 is movable, and the plug-in plate 4 passes through the limiting plate 21 and is inserted into the collecting plate 5. At the same time, it plugs into the grooves 22, thereby ensuring a stable connection between the switch plate 6 and the collecting plate 5. When the smear 3 makes a circular motion, under the action of centrifugal force, the inclined inserting plate 4 is tightly pressed into the groove 22, thereby ensuring the position stability between the switching plate 6 and the collecting plate 5.

[0023] The limiting member includes a plug-in plate 23 and two fixed plates 24 connected and fixed to the wiper 3. The slider 9 slides between the two fixed plates 24. A through groove 25 is provided on each of the fixed plates 24 and the slider 9. The plug-in plate 23 is plugged into and matched with the fixed plate 24 and the slider 9 through the through groove 25. Threaded rods 26 are threadedly connected to both ends of the plug-in plate 23. A hinged plate 27 is hinged between the slider 9 and the switching plate 6. Slide the slider 9 along the fixed plate 24 so that the through slot 25 on the slider 9 is aligned with the through slot 25 on the fixed plate 24, and insert the plug plate 23 into the through slot 25 to tighten the threaded rod 26 to ensure a stable connection between the slider 9 and the fixed plate 24, thereby driving the hinge plate 27 to rotate, so that the switching plate 6 moves along the collecting plate 5, and adjust the position of the switching member so that the rectangular block 10 is plugged into the rectangular slot 15, so that the diverter plate 7 is fixed in position and cannot rotate, which is convenient for collecting debris; By removing the slider 9 from the fixed plate 24 and separating the collecting plate 5 from the smear 3, the position of the movable adjustment switch member changes, so that the switching plate 6 moves along the collecting plate 5, the rectangular block 10 and the rectangular groove 15 are disconnected, and the connecting rod 11 is inserted into the circular groove 14, thereby facilitating the rotation of the diverter plate 7. The diverter plate 7 and the collecting plate 5 are rotated and separated, making it easier to clean the debris collected between the two adjacent diverter plates 7.

[0024] The connecting part includes a sleeve 28, in which a sleeve rod 29 is rotatably connected to the guide plate 8 through a spring sliding fit. There is a gap between the sleeve 28, the sleeve rod 29 and the smear 3. When the smear 3 makes a circular motion, the spring shakes, thereby moving the sleeve 28 and the sleeve rod 29, thereby slightly moving the guide plate 8, making it easier to collect the debris entering the smear 3, so that the debris enters the collection plate 5 and the diverter plate 7, and between the two adjacent diverter plates 7, thereby completing the collection.

[0025] The connecting member also includes a fixed plate 30 connected to the mounting plate 2, and a first movable plate 31 is rotatably connected to the bottom of the fixed plate 30. A second movable plate 32 is provided below the first movable plate 31. A T-shaped rod 33 is rotatably connected to the edges of the first movable plate 31 and the second movable plate 32. The other end of the T-shaped rod 33 is movably connected to the guide plate 8. The distance between the smear 3 and the mounting plate 2 is adjusted by the mounting plate 2, so that the smearing area of the smear 3 is changed. By adjusting the distance between the mounting plate 2 and the smear 3, the inclination of the guide plate 8 is adjusted in conjunction with the T-shaped rod 33. The smear 3 makes a circular motion, causing the spring to shake, reacting the T-shaped rod 33, causing the second movable disk 32 to rotate. The rotation of the second movable disk 32 also enhances the activity of the guide plate 8, making it easier to collect debris.
