Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural product storage and transportation, and particularly relates to a rapid picking and placing device for agricultural product logistics storage. Background Art

[0002] The storage of agricultural products is of crucial importance. From the perspective of regulating supply, it can balance the differences between peak and off-peak seasons. For example, when vegetables are scarce in winter, storage can ensure market supply. In terms of reducing losses, appropriate storage conditions can reduce the losses of agricultural products caused by spoilage, pests, etc. For example, standardized cold storage can extend the shelf life of fruits. Moreover, it can also help improve the added value of agricultural products, enhance the quality through scientific storage, and create conditions for deep processing. The storage link stabilizes the prices of agricultural products, avoids large fluctuations due to supply-demand imbalances, and effectively guarantees the income of farmers and market stability. During the storage process, the handling of agricultural products is particularly important, and it is necessary to complete the handling work of agricultural products in a time-saving and labor-saving manner and improve the efficiency of warehousing and outwarehousing.

[0003] The existing methods for handling agricultural products during storage mainly include the following aspects: manual handling, forklift handling, conveyor belt handling, etc. Manual handling is relatively laborious. Conveyor belts can only transport bulk products, while forklift handling can handle stacked boxed and bagged products. However, during the transportation of stacked bagged products, in order to ensure the handling efficiency, problems such as stacked agricultural products may occur. For example, after fruits are pressed, due to the large pressure at the bottom for a long time and the small supporting area, the outer skin is damaged, thereby reducing the quality of the product. After the outer skin is damaged, it is more likely to cause problems such as product spoilage. At the same time, the existing storage picking and placing devices have relatively single functions. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a rapid picking and placing device for agricultural product logistics storage.

[0005] The technical solution adopted to solve the above technical problem is: to provide a rapid picking and placing device for agricultural product logistics storage, including a bottom bracket. A bidirectional driving mechanism is fixedly connected between the front end and the rear end at the center of the top of the bottom bracket, and a connecting frame mechanism is fixedly connected to the bottom output end of the bidirectional driving mechanism;

[0006] A first transmission mechanism is fixedly connected between the two ends at the top of the bottom bracket. A plurality of buffer support mechanisms are installed on the first transmission mechanism. A rear-end driving component and a front-end steering component are respectively installed on both sides of the bottom bracket;

[0007] A lifting driving mechanism is fixedly connected to one side of the bottom bracket, and a second transmission mechanism is installed on the lifting driving mechanism.

[0008] Furthermore, the bidirectional driving mechanism includes two groups of supporting angle steels. Mounting fixing plates are placed on the tops of the two groups of supporting angle steels. A plurality of first bolt assemblies penetrate between the bottom bracket and the two groups of supporting angle steels and the two mounting fixing plates. The centers of the two mounting fixing plates are fixedly connected with bidirectional hydraulic cylinder assemblies respectively. The tops and bottoms of the two bidirectional hydraulic cylinder assemblies are respectively slidably connected with a first output rod and a second output rod. The output ends of the two first output rods are fixedly connected with top connecting gusset plates. Tension roller assemblies are arranged at both ends between the two top connecting gusset plates.

[0009] Through the above technical solution, when stacking crops is completed, the bidirectional hydraulic cylinder assemblies push the first output rods and the second output rods out simultaneously. The first output rods start to push the two connecting gusset plates and the two tension roller assemblies to rise, and the second output rods push the overall connecting frame mechanism to start descending, thereby reducing the tension degree of the first conveyor belt. At the same time, the buffer support mechanism can descend. Since the stroke between the connecting frame mechanism and the bottom bracket is small, after the connecting frame mechanism descends and contacts the bottom bracket, the connecting frame mechanism stops moving. At this time, the second output rods continue to rise and jack up.

[0010] Furthermore, the connecting frame mechanism includes a connecting bottom plate frame. The front and rear ends of the top of the connecting bottom plate frame are fixedly connected with side support struts respectively. A plurality of fixing ears are installed on the tops of the two side support struts. A plurality of adjusting rods are installed between the corresponding fixing ears between the two side support struts. Second bolt assemblies are arranged between the two ends of the plurality of adjusting rods and the corresponding fixing ears.

[0011] Through the above technical solution, when the two bidirectional hydraulic cylinder assemblies push the two second output rods to move downward, they will drive the two side support struts to descend through the connecting bottom plate frame, and then drive the plurality of adjusting rods to descend, releasing the support for the plurality of buffer support mechanisms.

[0012] Furthermore, the first transmission mechanism includes two side support vertical plates fixedly connected to the top of the bottom bracket. Two first transmission rollers are rotatably connected between the two side support vertical plates. A first conveyor belt is installed between the outer walls of the two first transmission rollers. The front end of one of the first transmission rollers is fixedly connected with a first belt pulley. A first motor assembly is installed on one side of the rear end face of one of the side support vertical plates. The output end of the first motor assembly is fixedly connected with a second belt pulley. Two transmission belts are installed between the first belt pulley and the second belt pulley. A plurality of blocking plates corresponding to the buffer support mechanisms are arranged on the mutually remote sides of the two side support vertical plates.

[0013] Through the above technical solution, the first motor assembly drives the second pulley to rotate, and then drives the first transmission roller to rotate through the two transmission belts and the first pulley. With the cooperation of another first transmission roller, the transmission of the first transmission belt can be realized. Bagged crops can be continuously placed on the first transmission belt and the position can be adjusted by moving.

[0014] Furthermore, on both sides of the centers of the two side support vertical plates, there are limit plates corresponding to the top connecting frame plates.

[0015] Through the above technical solution, the limit plates provide a limiting effect when the two side support vertical plates move up and down, ensuring the stability of the movement.

[0016] Furthermore, the buffer support mechanism includes two sliding blocks. A first support roller is rotatably connected between the two sliding blocks. A rubber sleeve is sleeved on the outer wall of the first support roller. Two reset springs are arranged at the bottoms of the two sliding blocks.

[0017] Through the above technical solution, during the normal transmission process, the first support roller and the rubber sleeve rotate to support the first transmission belt. When stacking bagged crops subsequently, the crops press on multiple first support rollers, and then the sliding blocks press on the corresponding reset springs, causing the overall buffer support mechanism to descend. This can increase the contact area between the packaging bag and the first pulley and prevent the crops at the bottom from being damaged due to excessive pressure.

[0018] Furthermore, the lifting drive mechanism includes an extension plate fixedly connected to one side of the bottom bracket. At the front and rear ends of the top of the extension plate, there are L-shaped support vertical plates fixedly connected. On the side where the two L-shaped support vertical plates are close to each other, there is a set of fixed sleeves fixedly connected. On one side of each of the two L-shaped support vertical plates, there is a U-shaped limit seat fixedly connected. Between the two sets of fixed sleeves and the extension plate, there are lifting hydraulic cylinders fixedly connected. At the tops of the two lifting hydraulic cylinders, there are support columns fixedly connected. On the tops of the two support columns, there are sprocket assemblies installed. On the two sprocket assemblies, there are drive chains installed. One end of each of the two drive chains is fixedly connected to the first transmission mechanism through a fixing member. The other ends of the two drive chains are fixedly connected to L-shaped sliding plates. On the two L-shaped sliding plates, there are multiple third bolt assemblies installed.

[0019] Through the above technical solution, after placing the agricultural crops on the second transmission mechanism, the two lifting hydraulic cylinders simultaneously push the corresponding support columns and sprocket assemblies upward. Since one end of the transmission chain is fixed by a fixing member, the other end of the transmission chain will be driven to rise as the sprocket assembly rises, thereby driving the two L-shaped sliding plates to slide upward in the corresponding U-shaped limit seats, realizing the driving of the overall second transmission mechanism and the bagged agricultural crops to rise. When the first conveyor belt rises to the same horizontal plane as the second conveyor belt, it stops.

[0020] Further, the second transmission mechanism includes two side brackets installed on the lifting drive mechanism. A second transmission roller, a third transmission roller, and a plurality of second support rollers are respectively rotatably connected between the two side brackets. A second conveyor belt is arranged between the second transmission roller and the third transmission roller. A second motor assembly is fixedly connected to the front end surface of the side bracket at the front end of the third transmission roller.

[0021] Through the above technical solution, when handling bagged agricultural crops, the agricultural crops are moved to one side of the second transmission mechanism and placed on the ground. At this time, the second motor assembly is started to drive the third transmission roller, and the second conveyor belt is transmitted in cooperation with the support of the second transmission roller. After one end of the bagged agricultural crops comes into contact with the second conveyor belt, it is driven onto the second conveyor belt and supported by a plurality of second support rollers.

[0022] Further, the diameter of the second transmission roller is larger than the diameter of the third transmission roller.

[0023] Through the above technical solution, the upper surface of the overall second conveyor belt is in an inclined surface structure, which facilitates the bagged agricultural crops to be more easily transmitted onto the second conveyor belt.

[0024] The beneficial effects of the present invention are as follows: (1) By designing a bidirectional drive mechanism and a first transmission mechanism, when stacking agricultural crops, the bidirectional hydraulic cylinder assembly pushes the first output rod and the second output rod out simultaneously. The first output rod starts to push the two connecting frame plates and the two tensioning roller assemblies upward, realizing the reduction of the tension degree of the first conveyor belt. The second output rod pushes the overall connecting frame mechanism to start descending, thereby realizing the descent of the connecting bottom plate frame, the two side support rods, and the plurality of adjusting rods. At this time, two sliding blocks in the plurality of buffer support mechanisms are pressed downward by the bagged agricultural crops and compress the corresponding return springs. The bottom of the stacked agricultural crops contacts the relaxed first pulley and a plurality of rubber sleeves, which can greatly increase the contact area between the packaging bag and the first pulley and avoid damage to the bottom agricultural crops due to excessive pressure; (2) By designing a lifting drive mechanism and a second transmission mechanism, the operation intensity of handling can be effectively reduced. At the same time, in cooperation with the transmission of the first transmission mechanism, the overall device can realize functions such as lifting, transporting, picking and placing, and transmitting agricultural crops, greatly improving the application range of the device.

Detailed implementation manners

[0041] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0042] As Figures 1-6 and Figure 10As shown in the figure, a rapid picking and placing device for agricultural product logistics storage in this embodiment includes a bottom bracket 1. A bidirectional driving mechanism 2 is fixedly connected between the front end and the rear end at the center of the top of the bottom bracket 1. The bidirectional driving mechanism 2 includes two groups of support angle steels 201. Installation fixing plates 203 are placed on the tops of the two groups of support angle steels 201. A plurality of first bolt assemblies 202 penetrate between the bottom bracket 1, the two groups of support angle steels 201 and the two installation fixing plates 203. Bidirectional hydraulic cylinder assemblies 204 are fixedly connected to the centers of the two installation fixing plates 203. The tops and bottoms of the two bidirectional hydraulic cylinder assemblies 204 are respectively slidably connected to a first output rod 205 and a second output rod 206. The output ends of the two first output rods 205 are fixedly connected to top connection frame plates 207. Tension roller assemblies 208 are arranged at both ends between the two top connection frame plates 207. When stacking crops is completed, the bidirectional hydraulic cylinder assemblies 204 push the first output rods 205 and the second output rods 206 to be pushed out simultaneously. The first output rod 205 starts to push the two connection frame plates 207 and the two tension roller assemblies 208 to rise, and the second output rod 206 pushes the overall connection frame mechanism 3 to start descending, thereby reducing the tension degree of the first conveyor belt 403, and at the same time enabling the buffer support mechanism 5 to descend. Since the stroke between the connection frame mechanism 3 and the bottom bracket 1 is small, after the connection frame mechanism 3 descends and contacts the bottom bracket 1, the connection frame mechanism 3 stops moving. At this time, the second output rod 206 continues to rise and jack up.

[0043] As Figures 1-7 shown, a connection frame mechanism 3 is fixedly connected to the bottom output end of the bidirectional driving mechanism 2. The connection frame mechanism 3 includes a connection bottom plate frame 301. Side support rods 302 are fixedly connected to the front and rear ends of the top of the connection bottom plate frame 301. A plurality of fixing ears 303 are installed on the tops of the two side support rods 302. A plurality of adjusting rods 304 are installed between the corresponding fixing ears 303 between the two side support rods 302. Second bolt assemblies 305 are arranged between the two ends of the plurality of adjusting rods 304 and the corresponding fixing ears 303. When the two bidirectional hydraulic cylinder assemblies 204 push the two second output rods 206 to move downward, they will drive the two side support rods 302 to descend through the connection bottom plate frame 301, thereby driving the plurality of adjusting rods 304 to descend, and releasing the support for the plurality of buffer support mechanisms 5.

[0044] As Figures 1-11As shown in the figure, a first transmission mechanism 4 is fixedly connected between the two ends at the top of the bottom bracket 1. The first transmission mechanism 4 includes two side support vertical plates 401 fixedly connected to the top of the bottom bracket 1. Two first transmission rollers 402 are rotatably connected between the two side support vertical plates 401. A first transmission belt 403 is installed between the outer walls of the two first transmission rollers 402. A first pulley 404 is fixedly connected to the front end of one of the first transmission rollers 402. A first motor assembly 405 is installed on one side of the rear end face of one of the side support vertical plates 401. The output end of the first motor assembly 405 is fixedly connected to a second pulley 406. Two transmission belts 407 are installed between the first pulley 404 and the second pulley 406. A plurality of blocking plates 408 corresponding to the buffer support mechanism 5 are provided on each of the two side support vertical plates 401 on the side away from each other. The first motor assembly 405 drives the second pulley 406 to rotate, and then drives the first transmission roller 402 to rotate through the two transmission belts 407 and the first pulley 404. With the cooperation of the other first transmission roller 402, the transmission of the first transmission belt 403 is realized. Bagged crops can be continuously placed on the first transmission belt 403 and the position can be adjusted by moving. Limit plates corresponding to the top connection frame plate 207 are provided on both sides of the centers of the two side support vertical plates 401. The limit plates provide a limiting function when the two side support vertical plates 401 move up and down, ensuring the stability of the movement.

[0045] As Figures 1-11 shown, a plurality of buffer support mechanisms 5 are installed on the first transmission mechanism 4. The buffer support mechanism 5 includes two sliding blocks 501. A first support roller 502 is rotatably connected between the two sliding blocks 501. A rubber sleeve 503 is sleeved on the outer wall of the first support roller 502. Two reset springs 504 are provided at the bottom of each of the two sliding blocks 501. During the normal transmission process, the first transmission belt 403 is supported by the rotating first support roller 502 and the rubber sleeve 503. When stacking bagged crops subsequently, the crops press on the plurality of first support rollers 502, and then the corresponding reset springs 504 are pressed through the sliding blocks 501, realizing the overall descent of the buffer support mechanism 5. Thereby, the contact area between the packaging bag and the first pulley 404 can be increased, and the crops at the bottom can be prevented from being damaged due to excessive pressure. A rear-end drive assembly 6 and a front-end steering assembly 7 are respectively installed on both sides of the bottom bracket 1.

[0046] As Figures 1-13As shown in the figure, a lifting drive mechanism 8 is fixedly connected to one side of the bottom bracket 1. The lifting drive mechanism 8 includes an extension plate 801 fixedly connected to one side of the bottom bracket 1. At the front and rear ends of the top of the extension plate 801, L-shaped support vertical plates 802 are fixedly connected. On the side where the two L-shaped support vertical plates 802 are close to each other, a set of fixed sleeves 803 are fixedly connected. On one side of each of the two L-shaped support vertical plates 802, a U-shaped limit seat 804 is fixedly connected. Lifting hydraulic cylinders 805 are fixedly connected between the two sets of fixed sleeves 803 and the extension plate 801. At the top of each of the two lifting hydraulic cylinders 805, a support column 806 is fixedly connected. At the top of each of the two support columns 806, a sprocket assembly 807 is installed. Transmission chains 808 are installed on the two sprocket assemblies 807. One end of each of the two transmission chains 808 and the first transmission mechanism 4 are fixedly connected by a fixing member 809. The other ends of the two transmission chains 808 are fixedly connected to L-shaped sliding plates 810. A plurality of third bolt assemblies 811 are installed on the two L-shaped sliding plates 810. After placing the agricultural crops on the second transmission mechanism 9, the two lifting hydraulic cylinders 805 simultaneously push the corresponding support columns 806 and sprocket assemblies 807 to rise. Since one end of the transmission chain 808 is fixed by the fixing member 809, as the sprocket assembly 807 rises, the other end of the transmission chain 808 will be driven to rise, thereby driving the two L-shaped sliding plates 810 to slide upward in the corresponding U-shaped limit seats 804, realizing driving the overall second transmission mechanism 9 and the bagged agricultural crops to rise. When the first conveyor belt 403 rises to the same horizontal plane as the second conveyor belt 905, it stops.

[0047] As Figures 1-15 shown in the figure, a second transmission mechanism 9 is installed on the lifting drive mechanism 8. The second transmission mechanism 9 includes two side brackets 901 installed on the lifting drive mechanism 8. A second transmission roller 902, a third transmission roller 903, and a plurality of second support rollers 904 are respectively rotatably connected between the two side brackets 901. A second conveyor belt 905 is arranged between the second transmission roller 902 and the third transmission roller 903. At the front end of the third transmission roller 903, a second motor assembly 906 is fixedly connected to the front end face of the side bracket 901. When handling bagged agricultural crops, the agricultural crops are moved to one side of the second transmission mechanism 9 and placed on the ground. At this time, the second motor assembly 906 is started to drive the third transmission roller 903 to drive, and with the support of the second transmission roller 902, the transmission of the second conveyor belt 905 is realized. After one end of the bagged agricultural crops contacts the second conveyor belt 905, it is driven onto the second conveyor belt 905 and supported by a plurality of second support rollers 904. The diameter of the second transmission roller 902 is larger than that of the third transmission roller 903, so that the upper surface of the overall second conveyor belt 905 is in an inclined plane structure, thereby facilitating the bagged agricultural crops to be more easily transmitted onto the second conveyor belt 905.

[0048] The working principle of this embodiment is as follows. When handling bagged crops, the crops are moved to one side of the second transmission mechanism 9 and placed on the ground. At this time, the second motor assembly 906 is started to drive the third transmission roller 903, and with the support of the second transmission roller 902, the transmission of the second transmission belt 905 is realized. After the bagged crops come into contact with one end of the second transmission belt 905, they are driven onto the second transmission belt 905 and supported by a plurality of second support rollers 904. Then, the two lifting hydraulic cylinders 805 simultaneously push the corresponding support columns 806 and sprocket assemblies 807 to rise. Since one end of the transmission chain 808 is fixed by the fixing member 809, as the sprocket assembly 807 rises, the other end of the transmission chain 808 will be driven to rise, thereby driving the two L-shaped sliding plates 810 to slide upward in the corresponding U-shaped limit seats 804, realizing the lifting of the overall second transmission mechanism 9 and the bagged crops. When the first transmission belt 403 rises to the same horizontal plane as the second transmission belt 905, it stops;

[0049] Then, the second motor assembly 906 continues to drive, and the bagged products are transmitted to the first transmission mechanism 4 through the second transmission belt 905. At the same time, the first motor assembly 405 drives the second pulley 406 to rotate, and then drives the first transmission roller 402 to rotate through the two transmission belts 407 and the first pulley 404. With the cooperation of another first transmission roller 402 and the two tension roller assemblies 208, the transmission of the first transmission belt 403 is realized. The bagged crops can be continuously placed on the first transmission belt 403 and the position can be adjusted by moving;

[0050] When stacking bagged products, they can be lifted in a way of stacking two or more bags, and then transferred to the first conveyor belt 403. After the transfer is completed, the double-acting hydraulic cylinder assembly 204 pushes the first output rod 205 and the second output rod 206 out simultaneously. The first output rod 205 starts to push the two connecting frame plates 207 and the two tension roller assemblies 208 to rise, so as to reduce the tension degree of the first conveyor belt 403. At the same time, the second output rod 206 pushes the overall connecting frame mechanism 3 to descend, thereby realizing the descent of the connecting bottom plate frame 301, the two side support rods 302 and the multiple adjusting rods 304. At this time, the two sliding blocks 501 in the multiple buffer support mechanisms 5 will be pressed down by the bagged crops without the support of the adjusting rods 304, and the corresponding return springs 504 will be compressed. The bottom of the stacked crops touches the relaxed first pulley 404 and the multiple rubber sleeves 503, which can greatly increase the contact area between the packaging bag and the first pulley 404, and avoid damage to the crops at the bottom due to excessive pressure. After the subsequent overall device moves to the designated position to complete unloading, the double-acting hydraulic cylinder assembly 204 pulls the first output rod 205 and the second output rod 206 back to their original positions. At this time, the multiple adjusting rods 304 rise to continue to support the multiple buffer support mechanisms 5, and the two tension roller assemblies 208 descend and return to their original positions to continue to support the first conveyor belt 403, making the first conveyor belt 403 taut.

[0051] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
