Description

Technical Field

[0001] This utility model relates to the field of diesel engine technology, specifically to a cooling grid for preventing grass entanglement in agricultural diesel engines. Background Technology

[0002] Agricultural diesel engines are internal combustion engines that use diesel fuel and employ compression ignition combustion. They are mainly used to provide power for agricultural machinery and equipment. Diesel engines can be divided into water-cooled diesel engines and air-cooled diesel engines according to their heat dissipation methods. In air-cooled diesel engines, the cooling fan used to drive airflow usually has a heat dissipation grille on its surface to block weeds and other obstructions.

[0003] Currently, the cooling grilles on the surface of some agricultural diesel engines can block weeds near the radiator fan casing. However, some weeds still manage to pass through the cooling grilles and enter the radiator fan. At this point, some weeds will become entangled on the surface of the fan blades. A large number of weeds continuously entangled on the surface of the fan blades will affect the rotation of the fan blades. Over time, the speed at which the radiator fan drives the airflow will decrease, which will easily affect the cooling effect on the diesel engine. Utility Model Content

[0004] The purpose of this utility model is to provide a cooling grid for preventing grass entanglement in agricultural machinery diesel engines, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling grid for preventing weed entanglement in agricultural diesel engines, comprising a grid body and mounting rings and discs respectively fixedly connected to both ends of the grid body, and further comprising: A rotatable barrier mechanism mounted on the surface of a disc, wherein one end of the barrier mechanism is provided with an extension shaft; A sleeve is fixedly fitted onto the surface of an extension shaft. A laterally movable cutting mechanism is mounted on the surface of the sleeve. The cutting mechanism includes a cutting blade and a connecting assembly that can drive the cutting blade to move.

[0006] Preferably, the connecting assembly includes a sliding disk, the cutting blade is fixedly connected to the surface of the sliding disk, the sliding disk is slidably sleeved on the surface of the sleeve, a fixing ring is fixedly connected to the surface of the sliding disk, the fixing ring is slidably sleeved on the surface of the sleeve, a crossbar is fixedly connected to the surface of the fixing ring, a connecting block is rotatably connected to one end of the crossbar, a hollow ring is fixedly sleeved on the surface of the extension shaft, and the connecting block is embedded in the surface of the hollow ring.

[0007] Preferably, the blocking mechanism includes a rotating shaft that rotates through the disc, one end of the rotating shaft is fixedly connected to a positioning disc, one end of the positioning disc is fixedly connected to a locking block, one end of the locking block is detachably connected to an extension shaft, one end of the extension shaft is provided with a locking groove, the surface of the locking block is in contact with the inner wall of the locking groove, and a plurality of cutting strips are fixedly connected to the surface of the positioning disc.

[0009] Preferably, a limiting ring is fixedly connected to the surface of the mounting ring, and one end of the cutting strip is in contact with the inner wall of the limiting ring.

[0010] Preferably, the surface of the grille body is arc-shaped, and the surface of one side of the disc protrudes from the surface of the grille body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention can cut weeds as they pass through the grille body, reducing the possibility of weeds extending further into the shell. When some weeds extend into the shell and come into contact with the surface of the fan blade body, the reciprocating connecting component can drive the cutting blade to chop the weeds on the surface of the fan blade body, reducing the pulling of weeds on the fan blade body.

[0014] 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.

[0015] Please see Figure 1-7 As shown, a cooling grid for preventing weed entanglement in a diesel engine for agricultural machinery includes a grid body 8 and mounting rings 7 and discs 9, which are fixedly connected to both ends of the grid body 8. The surface of the grid body 8 is arc-shaped, and one side of the disc 9 protrudes from the surface of the grid body 8. After weeds cover the surface of the grid body 8, air can enter the housing 2 from the side of the grid body 8, ensuring normal airflow. The grid body 8 can be installed on the housing 2 on the surface of the diesel engine body 1 by bolts and mounting rings 7. A turntable 4 is rotatably connected inside the housing 2, and several fan blade bodies 5 are fixedly connected to the surface of the turntable 4. The drive shaft of the diesel engine body 1 extends... The fan blade body 5 extends into the interior of the housing 2 and drives the turntable 4 inside the housing 2 to rotate. The fan blade body 5 rotates with the turntable 4 and drives the air to be discharged to the surface of the diesel engine body 1. The air flow can dissipate heat from the diesel engine body 1. The grille body 8 is used to reduce the entry of weeds into the interior of the housing 2. The use of the extension shaft 3, the turntable 4 and the fan blade body 5 is a mature technology used in existing diesel engines. The use of the extension shaft 3, the turntable 4 and the fan blade body 5 is well known to those skilled in the art and will not be described in detail here. The surface of the disc 9 is equipped with a blocking mechanism 10 that can cut weeds on the surface of the grille body 8. One end of the blocking mechanism 10 is provided with an extension shaft 3.

[0016] The extension shaft 3 is fixedly connected to the drive shaft inside the diesel engine body 1. When the diesel engine body 1 is started, the drive shaft drives the extension shaft 3 to rotate. Accordingly, through the cooperation of the slot 12 and the block 103, the extension shaft 3 can drive the positioning disk 102 to rotate. The blocking mechanism 10 includes a rotating shaft 101 that rotates through the disk 9. One end of the rotating shaft 101 is fixedly connected to the positioning disk 102. One end of the positioning disk 102 is fixedly connected to the block 103. One end of the block 103 is detachably connected to the extension shaft 3. One end of the extension shaft 3 has a slot 12. The surface of the block 103 contacts the inner wall of the slot 12. Several cutting strips 104 are fixedly connected to the surface of the positioning disk 102. The cross-section of the cutting strips 104 is diamond-shaped. One end of the cutting strips 104 is bent. This allows the cutting strips 104 to rotate with the positioning disk 102 and cut weeds that extend into the housing 2.

[0017] The cutting strip 104 rotates with the positioning plate 102 to cut weeds extending from the grid body 8 into the housing 2, thereby reducing the amount of weeds entangled on the surface of the grid body 8 and affecting airflow. Furthermore, cutting the weeds extending into the housing 2 prevents them from getting tangled between the grid body 8 and the fan blade body 5, thus avoiding any impact on the rotation of the fan blade body 5. A limiting ring 11 is fixedly connected to the surface of the mounting ring 7, and one end of the cutting strip 104 contacts the inner wall of the limiting ring 11. The limiting ring 11 increases the stability of the cutting strip 104. The surface of the extension shaft 3 is fixedly sleeved with... The sleeve 13 has a laterally movable cutting mechanism 6 installed on its surface. The cutting mechanism 6 includes a cutting blade 62 that can move laterally back and forth and a connecting component 61 that can drive the cutting blade 62 to move. The movement of the cutting blade 62 can cut the weeds wrapped around the surface of the fan blade body 5, so as to avoid the weeds pulling and affecting the normal use of the fan blade body 5. The connecting component 61 includes a sliding disk 611 that is slidably connected to the inside of the housing 2. The sliding disk 611 is slidably sleeved on the surface of the fan blade body 5. There are several cutting blades 62, and the cutting blades 62 are fixedly connected to the surface of the sliding disk 611.

[0018] When the sliding disc 611 moves, it can drive the cutting blade 62 to move inside the housing 2, so as to cut the weeds wrapped around the surface of the fan blade body 5, avoiding the weeds from affecting the rotation of the fan blade body 5. Afterwards, the installation ring 7 can be removed and the weeds inside the housing 2 can be quickly cleaned. Some of the chopped weeds can also be discharged through the airflow. The sliding disc 611 is slidably sleeved on the surface of the sleeve 13. A fixing ring 612 is fixedly connected to the surface of the sliding disc 611. The fixing ring 612 is slidably sleeved on the surface of the sleeve 13. A crossbar 613 is fixedly connected to the surface of the fixing ring 612. One end of the crossbar 613 rotates. A connecting block 614 is connected to the extension shaft 3. A hollow ring 63 is fixedly sleeved on the surface of the extension shaft 3. The connecting block 614 is embedded in the surface of the hollow ring 63. One side of the hollow ring 63 is inclined. The surface of the hollow ring 63 is in contact with the inner wall of the turntable 4. The inclined surface of the hollow ring 63 pushes the connecting block 614. When the hollow ring 63 rotates, the connecting block 614 can intermittently push and pull the crossbar 613 so that the lateral position of the sliding disk 611 can be moved through the fixing ring 612. When the cutting blade 62 moves with the sliding disk 611, it can cut the weeds on the surface of the fan blade body 5 to prevent the weeds from getting tangled on the surface of the fan blade body 5.

[0019] Working principle: When the diesel engine body 1 starts, its drive shaft drives the turntable 4 and extension shaft 3 to rotate. The fan blade body 5 rotates with the turntable 4, which can drive air to flow into the interior of the housing 2. At the same time, the grille body 8 can block most of the weeds from the outside. When a small amount of weeds extend into the interior of the housing 2, the locking block 103 cooperates with the locking groove 12 to drive the positioning plate 102 to rotate. The cutting strip 104 rotates with the positioning plate 102 to cut the weeds that have extended into the interior of the housing 2. In addition, when the hollow ring 63 rotates with the extension shaft 3, it cooperates with the connecting block 614 to drive the crossbar 613 to move back and forth laterally. Accordingly, the sliding plate 611 drives the cutting blade 62 to move back and forth on the surface of the fan blade body 5, which can prevent weeds from getting tangled on the surface of the fan blade body 5, ensure that the fan blade body 5 can rotate normally, the air can circulate normally, the heat dissipation operation can be carried out continuously, and ensure the normal use of the diesel engine body 1.
