Description

An ultra-thin TRD grooving machine blade Technical Field

[0001] This utility model relates to the field of TRD grooving machine technology, specifically an ultra-thin TRD grooving machine blade. Background Technology

[0002] The TRD (Tracking and Dipping) construction method has been widely used in engineering construction projects, especially in foundation pit curtain wall seepage prevention projects, due to its many advantages such as stable process, fast wall formation speed, and reliable quality. The TRD trenching machine is a specialized piece of equipment used for constructing continuous underground mixing walls of uniform thickness in cement-soil. The TRD trenching machine typically inserts a chainsaw-type cutting box into the stratum, horizontally advances and mixes the undisturbed soil, and simultaneously injects cement grout to form a continuous underground wall of uniform thickness in cement-soil. However, when constructing 400mm ultra-thin cement-soil cutoff walls, existing TRD trenching machines require matching blades. However, the blades used on these machines for 400mm ultra-thin cement-soil cutoff walls are generally fixed. If other sizes of cement-soil cutoff walls need to be constructed, different blades must be used, which is inconvenient. Furthermore, the trenching machine comes with a large number of blades of different sizes, increasing investment costs. The blade teeth are also prone to wear; when a blade becomes unusable due to wear, the entire blade assembly needs to be replaced, leading to resource waste and poor practicality.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1

[0035] Please refer to Figures 1-6. In this embodiment of the present invention, an ultra-thin TRD grooving machine blade includes: a rectangular plate 100 and a tooth-enhancing mechanism 200. The top of the rectangular plate 100 has an insertion groove 101, and the inner bottom surface of the insertion groove 101 has two threaded holes 102. One side of the rectangular plate 100 has multiple threaded grooves 103. Both ends of the rectangular plate 100 have limit grooves 105. Both ends of the rectangular plate 100 are provided with adjustment components. Both ends of the rectangular plate 100 are rotatably connected with two fixing bolts 110. The tooth-enhancing mechanism 200 is provided on one side of the rectangular plate 100.

[0036] Specifically, four fixing bolts 110 are used to easily install and fix the ultra-thin TRD grooving machine blade onto the chain body 300, and the rectangular plate 100 and the tooth-adding mechanism 200 are used in conjunction with the chain body 300 to facilitate cutting the land, making it more convenient to use.

[0037] As shown in Figures 3-4, in this embodiment, the adjustment component includes: a rectangular block 120, a limiting plate 130, a plug-in block 150, and a blade tooth body 160. The rectangular block 120 is disposed on the outside of the rectangular plate 100. The top of the rectangular block 120 has a plug-in groove 121, and the inner bottom surface of the plug-in groove 121 has two threaded holes 122. The limiting plate 130 is fixed to one side of the rectangular block 120. The limiting plate 130 is slidably connected to the corresponding limiting groove 105, and the inner bottom surface of the limiting groove 105 has a plurality of connecting holes 108 evenly distributed. One end of the limiting plate 130 has a threaded hole 131, and one end of the limiting plate 130 is provided with a fixing bolt 132. The end is screwed into the corresponding connecting hole 108 and threaded hole 131. The first plug block 150 is inserted into the second plug slot 121. Both ends of the first plug block 150 are screwed into the fixing bolt 151, and the fixing bolt 151 is screwed into the corresponding threaded hole 122. The first cutter body 160 is fixed to the top of the first plug block 150. One end of one side of the rectangular block 120 is fixed to the connecting rod 140. Both ends of the other side of the rectangular plate 100 are provided with connecting grooves 106, and the connecting rod 140 is slidably connected to the corresponding cutter body 160. The internal contour of the second plug slot 121 is the same as the internal contour of the first plug slot 101, and the diameter of the second threaded hole 122 is the same as the diameter of the first threaded hole 102.

[0038] In this embodiment, by inserting multiple plug-in blocks 150 into the two plug-in slots 121 or 101 respectively, and tightening the fixing bolts 151, the plug-in blocks 150 and the blade body 160 are easily installed and fixed. By pulling the two rectangular blocks 120 to the appropriate position, and then screwing the two fixing bolts 132 into the corresponding connecting holes 108 and threaded holes 131 respectively, the position of the limiting plate 130 and the rectangular blocks 120 is easily fixed. This facilitates the installation and fixing of the corresponding plug-in blocks 150 and the blade body 160 in the appropriate position, and makes it easy to replace the worn blade body 160. The movement of the rectangular blocks 120 will drive the connecting rod 140 to move, thereby improving the stability of the rectangular blocks 120 after movement by using the connecting rod 140 and the connecting slot 106 together.

[0039] As shown in Figure 4, in this embodiment, rectangular grooves 107 are provided at both ends of the bottom of the rectangular plate 100, and the two rectangular grooves 107 are respectively connected to the corresponding multiple connecting holes 108. A baffle 170 is slidably connected inside the rectangular groove 107.

[0040] In practice, two baffles 170 are used to cover multiple connecting holes 108 and to limit the two fixing bolts 132, thus preventing the fixing bolts 132 from shaking after the ultra-thin TRD grooving machine blade is used, thereby ensuring the stability of the ultra-thin TRD grooving machine blade during use.

[0041] Example 2

[0042] Based on Example 1, the applicability of the ultra-thin TRD grooving machine blade has been improved in order to adjust the number of cutting teeth as needed.

A displacement assembly is provided on the connecting plate 210. The two moving blocks 250 are respectively disposed at both ends of the connecting plate 210. Insertion grooves 251 are provided on the top of the moving blocks 250, and two insertion grooves 260 are provided on the inner bottom surface of the insertion grooves 251. The component includes a threaded hole 252, two plug-in blocks 260 which are slidably plugged into two plug-in slots 251 respectively, and fixing bolts 261 which are screwed into both ends of the plug-in blocks 260. The fixing bolts 261 are screwed into the corresponding threaded hole 252. Two blade bodies 270 are fixedly connected to the top of the two plug-in blocks 260 respectively. The displacement component includes a rectangular tube 230 and two push plates 240. The rectangular tube 230 is fixed at the middle position of the placement hole 211. A bidirectional lead screw 231 is rotatably connected at the middle position of the rectangular tube 230. The two push plates 240 are screwed into both ends of the bidirectional lead screw 231 respectively. The two push plates 240 are slidably connected to both ends of the placement hole 211 respectively. The two push plates 240 are fixedly connected to the corresponding two moving blocks 250 respectively.

[0044] In specific implementation, by screwing multiple fixing bolts 220 into the corresponding threaded grooves 103, the tooth-adding mechanism 200 can be easily installed, fixed, and disassembled. By inserting the plug block 260 into the corresponding plug groove 251 and screwing the fixing bolt 261 into the corresponding threaded hole 252, the plug block 260 and the tooth body 270 can be easily installed and fixed. Then, by rotating the bidirectional lead screw 231, the two push plates 240 can be moved, thereby facilitating the adjustment of the positions of the moving block 250, the plug block 260, and the tooth body 270, thus improving the applicability of the ultra-thin TRD grooving machine blade.
