[0015] Compared with the prior art, the utility model provides a belt surface groove cutting device based on agricultural machinery V-belt cutting, which has the following beneficial effects:

[0016] 1. The utility model sets a limit block, the width of which is equal to the spacing of the limit plates. The limit blocks are symmetrically installed on the front and rear sides of the lower pressure plate with the center of the lower pressure plate as a reference. The top surface of the limit plate is fixedly connected to the lower ends of the limit columns on the front and rear sides of the connecting plate. The limit columns and the connecting plate form a sliding connection. The downward pressure spring is located between the connecting plate and the lower pressure plate. When cutting, the downward pressure piston drives the connecting plate to move downward. The limit block first contacts the V-belt, and then the distance between the connecting plate and the lower pressure plate is reduced. The downward pressure spring is compressed and contracted. When contracting, the downward pressure spring applies a downward force to the lower pressure plate, thereby clamping the V-belt with the limit block and the support plate to avoid driving the V-belt to rotate when the tool contacts the V-belt, thereby affecting the cutting effect.

[0017] 2. The utility model adopts the setting of the lower pressure plate. Since the tool is installed in the center of the lower pressure plate and the upper end of the tool is fixedly connected to the connecting plate, a sliding connection is formed between the tool and the lower pressure plate. After the limit block contacts the V-belt, the distance between the lower pressure plate and the connecting plate decreases with the extension of the lower pressure piston, so that the tool will pass through the lower pressure plate to cut the V-belt. After the cutting is completed, the connecting plate will move upward under the drive of the lower pressure piston. Since the lower pressure spring will recover with the contraction of the lower pressure piston, before the lower pressure spring is completely restored, the lower pressure spring will keep the position of the lower pressure plate unchanged, and the tool will move upward. After the lower pressure spring is restored, the bottom end of the tool will move to the inside of the lower pressure plate. This method can prevent the cut part of the V-belt from being stuck in the inside of the tool and affecting the subsequent cutting operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The width of the limit block 26 is equal to the spacing of the limit plates 13. The limit block 26 is symmetrically installed on the front and rear sides of the lower pressure plate 25 with the center of the lower pressure plate 25 as the reference. A sliding connection is formed between the tool 27 and the lower pressure plate 25, and the upper end of the tool 27 is fixedly connected to the bottom surface of the connecting plate 22.

[0035] When in use, firstly, the position of the slider 14 is adjusted by rotating the screw 112 through the turntable 113, so that the two ends of the V-belt are embedded in the guide wheel 17 and the V-belt is located between the limit plates 13. Then, the position between the connecting columns 16 is increased by rotating the screw 112 through the turntable 113 to tighten the V-belt.

The limit block 26 is symmetrically installed on the front and rear sides of the lower pressure plate 25 with the center of the lower pressure plate 25 as the reference.

After the cutting is completed, the connecting plate 22 will move upward under the drive of the pressing piston 21. Due to the pressing spring 24 It will recover with the contraction of the pressing piston 21. Before the pressing spring 24 is fully restored, the pressing spring 24 will keep the position of the pressing plate 25 unchanged, and the tool 27 will move upward. After the pressing spring 24 is restored, the bottom end of the tool 27 will move to the inside of the pressing plate 25.
