[0025] The following combines the drawings Figures 1-5 The application is further explained in detail.
[0026] The embodiment of the utility model provides a kind of harvester cutting assembly test equipment, embodiment one: refer to Figure 1 With Figure 2 Harvester cutting assembly test equipment includes rack 1 and abrasive poking assembly 2.Rack 1 is equipped with the abrasive box 11 of top open, abrasive box 11 is filled with abrasive for testing cutting assembly.The reciprocating mechanism 12 of sliding is equipped on rack 1, cutting assembly is installed on reciprocating mechanism 12 and is inserted in the abrasive in abrasive box 11, cutting assembly and reciprocating mechanism 12 synchronous movement.Abrasive poking assembly 2 is rotated in abrasive box 11, abrasive poking assembly 2 is located at one side of cutting assembly and is suitable for poking abrasive in abrasive box 11 to cutting assembly, so that the abrasive at the position of cutting assembly is always saturated.
[0027] Abrasive box 11 is welded on rack 1, and abrasive box 11 is not prone to collision with cutting assembly during testing process.Reciprocating mechanism 12 is located at the opening of abrasive box 11, and reciprocating mechanism 12 is located above abrasive box 11.
[0028] Refer to Figure 2 With Figure 3The reciprocating mechanism 12 comprises a reciprocating plate 13, an oscillating driver 14 and an oscillating connecting rod 15. The frame 1 is fixedly provided with a guide rail above the abrasive box 11, the guide rail is slidably provided with a sliding block, the reciprocating plate 13 is bolted to the sliding block and synchronously orientedly slides with the sliding block. The guide rail and the sliding block are arranged to make the reciprocating plate 13 slide more smoothly. Each component in the cutting assembly is bolted to the reciprocating plate 13 and synchronously moves with the reciprocating plate 13. The reciprocating plate 13 is bolted with an adapter plate, the adapter plate extends to one end of the reciprocating plate 13 and is in a suspended state. The oscillating driver 14 is located at the end of the adapter plate away from the reciprocating plate 13 and above the adapter plate. The oscillating connecting rod 15 is sleeved and fixed on the rotating shaft of the oscillating driver 14 on one side, and is hingedly connected with the adapter plate on the other side, so that the oscillating driver 14 drives the oscillating connecting rod 15 to drive the reciprocating plate 13 and the cutting assembly to move directionally and reciprocally after the oscillating driver 14 operates.
[0029] Supposing that one side of the frame 1 is the front side and the other side is the rear side, the cutting assembly is located near the front side of the frame 1 in the abrasive box 11, and the abrasive stirring assembly 2 is located near the rear side of the frame 1. In this way, a large amount of abrasive can be provided at the position of the abrasive stirring assembly 2.
[0030] Referring to Figure 2 and Figure 4 The abrasive stirring assembly 2 comprises a rotating column 21 and a stirring rod 22. The stirring rod 22 is arranged on the outer wall of the rotating column 21 and synchronously rotates with the rotating column 21. A plurality of stirring rods 22 are arranged on the rotating column 21 along the axial direction of the rotating column 21. The axial directions of adjacent two stirring rods 22 are perpendicular to each other, so that the abrasives at the positions of adjacent two stirring rods 22 can be stirred alternately. In combination with the reciprocating movement of the cutting assembly, the abrasives can be stirred to the place where the cutting assembly is about to move to better and more timely. The rotating column 21 is rotatably arranged on the abrasive box 11.
[0031] In detail, the stirring rod 22 is a cylindrical rod. Threaded holes are formed in the outer wall of the rotating column 21 and penetrate the rotating column 21 along the radial direction of the rotating column 21. The two ends of each threaded hole are threadedly provided with a stirring rod 22. One end of each stirring rod 22 is inserted into the threaded hole and threadedly connected with the rotating column 21. The directions in which adjacent two threaded holes are formed are perpendicular to each other, so that the axial directions of adjacent two stirring rods 22 on the rotating column 21 are perpendicular to each other.
[0032] One end of the rotating column 21 penetrates the abrasive box 11, and the two ends of the rotating column 21 protrude from the abrasive box 11 and are rotatably connected with the abrasive box 11. Bearings are sleeved on the two ends of the rotating column 21, and the outer rings of the bearings are fixed on the frame 1, thereby improving the stability of the rotating column 21 after installation.
[0033] Referring to Figure 1 and Figure 4The one end of the abrasive box 11 is provided with a rotating motor 16, and the rotating motor 16 is fixedly installed on the rack 1. The motor shaft of the rotating motor 16 is keyed connected with a driving pulley, and one end of the rotating column 21 is keyed connected with a driven pulley, and the driving pulley and the driven pulley are connected through a transmission belt. When the rotating motor 16 operates, the driving pulley will be driven to rotate; and the driven pulley will also rotate synchronously with the driving pulley under the action of the transmission belt, and then the rotating column 21 is driven to rotate.
[0034] The implementation principle of the harvesting machine cutting assembly test equipment in the embodiment of the application is as follows: when the cutting assembly is tested, the cutting assembly is first installed on the reciprocating plate 13 through bolts, then the abrasive is added into the abrasive box 11, and the cutting assembly is inserted into the abrasive. In the process that the reciprocating plate 13 drives the cutting assembly to reciprocate under the driving of the swing driver 14, the abrasive poking assembly 2 will continuously poke the abrasive on one side of the cutting assembly to the test position of the cutting assembly, so that the abrasive at the position of the cutting assembly is always saturated, which can reduce the error of the test result and improve the accuracy of the test result. When one poking rod 22 is seriously worn, the poking rod 22 can be directly screwed off from the rotating column 21 for replacement.
[0035] In the embodiment two, refer to Figure 5 The difference between the embodiment and the embodiment one is that the poking rod 22 is a rectangular plate body, so that the range of poking the abrasive is wider. The outer wall of the rotating column 21 is provided with a slot 211, and the slot 211 penetrates through the rotating column 21 along the radial direction of the rotating column 21. The poking rod 22 is inserted into the slot 211, and the two ends of the poking rod 22 protrude out of the slot 211. The rotating column 21 is provided with a bolt, the threaded end of the bolt is screwed through the rotating column 21 and the poking rod 22 and is screwed with a nut, so that the poking rod 22 is fixed on the rotating column 21.
[0036] The two opposite sides of the two ends of the poking rod 22 are provided with grooves 221, and each groove 221 is adhered with a ceramic block 23 through strong glue. The width of the ceramic block 23 is the same as the width of the poking rod 22, and the side of the ceramic block 23 close to the slot of the groove 221 protrudes out of the groove 221. When the abrasive is poked, the ceramic block 23 will directly contact and poke the abrasive, and the ceramic itself has good wear resistance, so that the ceramic block 23 directly contacts with the abrasive, which can improve the service life of the poking rod 22.
