Description

Technical Field

[0001] The invention relates to the field of transportation equipment, and in particular to a blocking structure for loading and unloading rollers. Background Art

[0002] The loading and unloading rollers are very stable when transporting materials. They can also use the inertia of the materials themselves to transport them, reducing the energy loss required for material transportation. Since the loading and unloading rollers will continue to transport materials under the existence of the inertia of the materials themselves, a blocking structure is required to ensure that the position where the materials stop is fixed;

[0003] The blocking structure used for the current loading and unloading rollers is as follows Figure 5 As shown, a hydraulic push rod drives a blocking plate to block the material. The blocking effect of this mechanism is good, but if the material is above the blocking plate, when the hydraulic push rod pushes the blocking plate, the blocking plate will flip the material over. In the process of the material being flipped over, it is easy to cause damage to the material, thereby reducing the safety of the material during transportation. Therefore, a blocking structure for loading and unloading rollers is needed to ensure the safety of the material during transportation. Summary of the Invention

[0004] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide a blocking structure for loading and unloading rollers. Through the blocking mechanism, when the material needs to be blocked, the hydraulic cylinder can be opened, and the hydraulic cylinder pushes the blocking mechanism through the hydraulic rod to make the blocking mechanism block at the material trough to prevent the material from passing through the material trough and achieve a blocking effect. When the material is just in the middle position of the material trough, the blocking plate and the driving plate can play a buffering role. The hydraulic cylinder will push the driving plate to move on the inner side of the blocking plate, and the height of the blocking plate remains unchanged. After the material passes through the material trough, the blocking plate will seal the material trough again, thereby ensuring the safety of the material.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A blocking structure for a loading and unloading roller comprises a fixed plate, a blocking mechanism is provided on one side of the fixed plate, a hydraulic cylinder is provided at the bottom of the blocking mechanism, the hydraulic cylinder is used to push the blocking mechanism, a side of the fixed plate close to the blocking mechanism is fixedly connected to a limiting track, a side of the blocking mechanism close to the limiting track is fixedly connected to a limiting slider that fits with the limiting track, a material trough is provided on the top of the fixed plate, and the material trough is used to pass the material;

[0007] The blocking mechanism includes a blocking plate, which is used to block the material trough and limit the position of the material. A driving plate is inserted into the bottom surface of the blocking plate, and the driving plate is used to drive the blocking plate. The bottom surface of the driving plate is fixedly connected to a connecting plate, and the bottom surface of the connecting plate is connected to the output end of the hydraulic cylinder through a hydraulic rod.

[0008] As a further solution of the present invention: a support plate is provided on the top surface of the blocking plate.

[0009] As a further solution of the present invention: the support plate includes a plate body, the top surface of the plate body is equipped with a guide roller through a rotating shaft, the top surface of the blocking plate is fixedly connected to a telescopic rod, and the bottom surface of the plate body is provided with a telescopic groove near the telescopic rod, which fits with the telescopic rod.

[0010] As a further solution of the present invention: an oil chamber is opened in the inner cavity of the baffle plate, and the oil chamber fits with the drive plate. An oil pump is fixedly connected to the middle position of the baffle plate away from the fixed plate. The output end of the oil pump is connected to a connecting oil pipe, and the end of the connecting oil pipe away from the oil pump is communicated with the top of the oil chamber.

[0011] As a further solution of the present invention: a buffer spring is connected between the middle position of the bottom surface of the plate body and the top surface of the blocking plate, and a connecting terminal is provided on the inner side of the buffer spring.

[0012] As a further solution of the present invention: the connecting terminal is divided into two sections, which are respectively connected to the bottom surface of the plate body and the top surface of the blocking plate, and the connecting terminal is connected in series with the circuit driving the oil pump.

[0013] As a further solution of the present invention: the length of the support plate is greater than the length of the material trough, and the surface formed by the vertical center line of the support plate and the vertical center line of the material trough is perpendicular to the side of the fixed plate, ensuring that when the material passes through the material trough, the support plate can play both a supporting role and a guiding role, ensuring that the material passes through the material trough effectively.

[0014] As a further solution of the present invention: the speed at which the volume of the hydraulic oil inside the oil chamber decreases is equal to the speed at which the drive plate enters the oil chamber. When the oil pump is started, the oil pump can extract the hydraulic oil in the oil chamber through the connecting oil pipe. Since the speed at which the volume of the hydraulic oil inside the oil chamber decreases is equal to the speed at which the drive plate enters the oil chamber, when the hydraulic cylinder pushes the drive plate through the hydraulic rod, the height of the blocking plate will remain unchanged, preventing the blocking plate from overturning the material and causing damage to the material, thereby improving the protection effect on the material.

[0015] Beneficial effects of the present invention:

[0016] 1. In the present invention, by setting up a blocking mechanism, when it is necessary to block the material, the hydraulic cylinder can be opened, and the hydraulic cylinder pushes the blocking mechanism through the hydraulic rod, so that the blocking mechanism blocks the material at the material trough, preventing the material from passing through the material trough, thereby achieving a blocking effect. When the material is just in the middle position of the material trough, a buffering effect can be played between the blocking plate and the driving plate. The hydraulic cylinder will push the driving plate to move on the inner side of the blocking plate, while the height of the blocking plate remains unchanged. After the material passes through the material trough, the blocking plate will seal the material trough again, thereby ensuring the safety of the material.

[0017] 2. In the present invention, the support plate arranged on the top surface of the blocking plate can play a buffering role. When the material passes through the material chute, the guide roller on the top surface of the plate body can reduce the friction between the material and the plate body, and play a guiding role, ensuring that the material can pass through the material chute quickly.

[0018] 3. In the present invention, by setting the support plate, in the process of the plate body approaching the material, the plate body is subjected to the gravity of the material to overcome the elastic force of the buffer spring, so that the two sections of the connecting terminal are connected, and the circuit of the oil pump is connected, thereby starting the oil pump. After the material passes through the material chute, the plate body is not affected by external force. At this time, the elastic force of the buffer spring will act on the plate body, so that the two sections of the connecting terminal are separated, and the circuit of the oil pump is disconnected, so that the oil pump stops working. At this time, the high-pressure oil storage bottle connected to the oil pump will return the hydraulic oil from the connecting oil pipe to the oil chamber, ensuring that the blocking plate automatically rises, thereby realizing automatic blocking of the blocking plate.

DETAILED DESCRIPTION

[0026] 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 any creative efforts shall fall within the scope of protection of the present invention.

[0027] like Figures 1-4 As shown, a blocking structure for an upper and lower material roller comprises a fixed plate 1, which is arranged in the middle position of the upper and lower material rollers, a blocking mechanism 2 is provided on one side of the fixed plate 1, a hydraulic cylinder 3 is provided at the bottom of the blocking mechanism 2, and the bottom end of the hydraulic cylinder 3 is fixed on the upper and lower material rollers, and the hydraulic cylinder 3 is used to push the blocking mechanism 2, and the fixed plate 1 is fixedly connected to a limiting rail 4 on one side near the blocking mechanism 2, and a limiting slider 5 is fixedly connected to the side of the blocking mechanism 2 near the limiting rail 4, which fits with the limiting rail 4. A material trough 6 is provided on the top of the fixed plate 1, and the material trough 6 is used to pass the material, and the blocking mechanism 2 comprises a blocking plate 21, and the blocking plate 21 is used to block the material trough 6 and limit the position of the material. A driving plate 22 is inserted into the bottom surface of the blocking plate 21, and the driving plate 22 is used to drive the blocking plate 21. The bottom surface of the driving plate 22 is fixedly connected to a connecting plate 23, and the bottom surface of the connecting plate 23 is connected to the output end of the hydraulic cylinder 3 through a hydraulic rod;

[0028] During operation, the loading and unloading rollers can transport the material to the fixed plate 1. When the material needs to be blocked, the hydraulic cylinder 3 can be opened. The hydraulic cylinder 3 pushes the blocking mechanism 2 through the hydraulic rod to block the blocking mechanism 2 at the material trough 6 to prevent the material from passing through the material trough 6 and achieve a blocking effect. When the material is just in the middle position of the material trough 6, the blocking plate 21 and the driving plate 22 can play a buffering role. The hydraulic cylinder 3 will push the driving plate 22 to move on the inner side of the blocking plate 21, and the height of the blocking plate 21 remains unchanged. After the material passes through the material trough 6, the blocking plate 21 will seal the material trough 6 again, which can ensure the safety of the material.

[0029] like Figure 4 As shown, a support plate 24 is provided on the top surface of the blocking plate 21. The support plate 24 includes a plate body 241. A guide roller 242 is mounted on the top surface of the plate body 241 via a rotating shaft. The top surface of the blocking plate 21 is fixedly connected to the telescopic rod 211. A telescopic groove is provided on the bottom surface of the plate body 241 near the telescopic rod 211 to fit with the telescopic rod 211.

[0030] The support plate 24 arranged on the top surface of the blocking plate 21 can play a buffering role. When the material passes through the material chute 6, the guide roller 242 on the top surface of the plate body 241 can reduce the friction between the material and the plate body 241, and play a guiding role to ensure that the material can pass through the material chute 6 quickly.

[0031] like Figure 3 As shown, an oil chamber 27 is formed in the inner cavity of the blocking plate 21, and the oil chamber 27 and the driving plate 22 fit together. An oil pump 25 is fixedly connected to the middle position of the blocking plate 21 away from the fixed plate 1. The output end of the oil pump 25 is connected to a connecting oil pipe 26. The end of the connecting oil pipe 26 away from the oil pump 25 is connected to the top of the oil chamber 27. The speed at which the volume of the hydraulic oil in the oil chamber 27 decreases is equal to the speed at which the driving plate 22 enters the oil chamber 27.

[0032] When the oil pump 25 is started, the oil pump 25 can extract the hydraulic oil in the oil chamber 27 through the connecting oil pipe 26. Since the speed at which the volume of the hydraulic oil inside the oil chamber 27 decreases is equal to the speed at which the driving plate 22 enters the oil chamber 27, when the hydraulic cylinder 3 pushes the driving plate 22 through the hydraulic rod, the height of the blocking plate 21 will remain unchanged, preventing the blocking plate 21 from overturning the material and causing damage to the material, thereby improving the protection effect on the material.

[0033] like Figure 4 As shown, a buffer spring 243 is connected between the middle position of the bottom surface of the plate body 241 and the top surface of the blocking plate 21. A connecting terminal 244 is provided on the inner side of the buffer spring 243. The connecting terminal 244 is divided into two sections, which are respectively connected to the bottom surface of the plate body 241 and the top surface of the blocking plate 21. The connecting terminal 244 is connected in series with the circuit driving the oil pump 25.

[0034] In the process of plate 241 approaching the material, the gravity of the material will overcome the elastic force of buffer spring 243 on plate 241, so that the two sections of connecting terminal 244 are connected, and the circuit of oil pump 25 is connected, thereby starting oil pump 25. When the material passes through material chute 6, plate 241 is not affected by external force. At this time, the elastic force of buffer spring 243 will act on plate 241, so that the two sections of connecting terminal 244 are separated, thus disconnecting the circuit of oil pump 25 and stopping oil pump 25. At this time, the high-pressure oil storage bottle connected to oil pump 25 will return hydraulic oil from connecting oil pipe 26 to oil chamber 27, ensuring that blocking plate 21 automatically rises, thereby realizing automatic blocking of blocking plate 21.

[0035] like Figure 2 As shown, the length of the support plate 24 is greater than the length of the material trough 6, and the surface formed by the vertical center line of the support plate 24 and the vertical center line of the material trough 6 is perpendicular to the side surface of the fixed plate 1, ensuring that when the material passes through the material trough 6, the support plate 24 can play both a supporting role and a guiding role, ensuring that the material passes through the material trough 6 effectively.

[0036] Working principle of the present invention: When working, the loading and unloading rollers can transport the materials to the fixed plate 1. When the blocking mechanism 2 needs to be activated, it is divided into the following two situations:

[0037] When the material is on both sides of the blocking mechanism 2, the hydraulic cylinder 3 is opened, and the hydraulic cylinder 3 pushes the blocking mechanism 2 through the hydraulic rod, so that the blocking mechanism 2 is blocked at the material chute 6, preventing the material from passing through the material chute 6, thereby achieving a blocking effect;

[0038] When the material is at the top of the blocking mechanism 2, the support plate 24 arranged on the top surface of the blocking plate 21 can play a buffering role. When the material passes through the material chute 6, the guide roller 242 on the top surface of the plate body 241 can reduce the friction between the material and the plate body 241 and play a guiding role, ensuring that the material can quickly pass through the material chute 6. In the process of the plate body 241 approaching the material, the plate body 241 is subjected to the gravity of the material and will overcome the elastic force of the buffer spring 243, so that the two sections of the connecting terminal 244 are connected, that is, The circuit of the oil pump 25 is connected, thereby starting the oil pump 25. After the material passes through the material chute 6, the plate 241 is not affected by external force. At this time, the elastic force of the buffer spring 243 will act on the plate 241, separating the two sections of the connecting terminal 244, thereby disconnecting the circuit of the oil pump 25 and stopping the oil pump 25. At this time, the high-pressure oil storage bottle connected to the oil pump 25 will return the hydraulic oil from the connecting oil pipe 26 to the oil chamber 27, ensuring that the blocking plate 21 automatically rises, thereby realizing automatic blocking of the blocking plate 21.

However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
