Description

Technical Field

[0001] The invention belongs to the technical field of agricultural product storage and transportation, and in particular relates to a quick pick-and-place device for agricultural product logistics storage. Background Art

[0002] Agricultural product storage is crucial. From a supply perspective, it helps balance seasonal discrepancies. For example, when vegetables are scarce in winter, warehousing can help ensure market supply. Furthermore, proper storage conditions can reduce losses caused by spoilage, pests, and other factors. For example, standardized refrigeration can extend the shelf life of fruit. It also helps increase the added value of agricultural products, improving quality through scientific storage and facilitating further processing. Warehousing stabilizes agricultural product prices, preventing significant fluctuations due to supply and demand imbalances, and effectively safeguarding farmers' profits and market stability. The handling of agricultural products during storage is particularly crucial, saving time and effort and improving the efficiency of both incoming and outgoing shipments.

[0003] The methods used in existing agricultural product storage for transportation mainly include the following aspects: manual transportation, forklift transportation, conveyor belt transportation, etc. Manual transportation is relatively laborious, and conveyor belts can only transport bulk products, while forklift transportation can transport stacked boxed and bagged products. However, during the transportation of stacked bagged products, in order to ensure the efficiency of transportation, the problem of stacked agricultural products will arise. For example, after the fruit is compressed, the long-term high pressure at the bottom and the small support area will cause damage to the skin, thereby reducing the quality of the product. Damaged skin is more likely to lead to problems such as product deterioration. At the same time, the functions of existing storage and placement devices are relatively simple. Summary of the Invention

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

[0005] The technical solution adopted to solve the above technical problems is: to provide a quick pick-up and placement device for agricultural product logistics storage, including a bottom bracket, a bidirectional drive mechanism fixedly connected between the front and rear ends of the top center of the bottom bracket, and a connecting frame mechanism fixedly connected to the bottom output end of the bidirectional drive mechanism;

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

[0007] One side of the bottom bracket is fixedly connected with a lifting drive mechanism, and a second transmission mechanism is installed on the lifting drive mechanism.

[0008] Furthermore, the bidirectional drive mechanism includes two groups of supporting angle steels, and mounting plates are placed on the tops of the two groups of supporting angle steels. A plurality of first bolt assemblies are passed through the bottom bracket and the two groups of supporting angle steels and the two mounting plates. The centers of the two mounting plates are fixedly connected with a bidirectional hydraulic cylinder assembly, and 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, and the output ends of the two first output rods are fixedly connected with a top connecting frame plate, and tensioning roller assemblies are provided at both ends between the two top connecting frame plates.

[0009] Through the above technical solution, when the crops are stacked, the bidirectional hydraulic cylinder assembly pushes the first output rod and the second output rod out at the same time, the first output rod begins to push the two connecting frame plates and the two tensioning roller assemblies to rise, and the second output rod pushes the entire connecting frame mechanism to start descending, thereby reducing the tension of the first conveyor belt and enabling the buffer support mechanism to 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, and at this time the second output rod continues to rise and lift up.

[0010] Furthermore, the connecting frame mechanism includes a connecting base frame, and the front and rear ends of the top of the connecting base frame are fixedly connected to side support frame rods, and the tops of the two side support frame rods are each installed with a plurality of fixing ears, and a plurality of adjustment rods are installed between the corresponding fixing ears between the two side support frame rods, and a second bolt assembly is provided between the two ends of the plurality of adjustment 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 frame rods to descend by connecting the base frame, and then drive the descent of multiple adjustment rods, thereby releasing the support for multiple buffer support mechanisms.

[0012] Furthermore, the first transmission mechanism includes two side support uprights fixedly connected to the top of the bottom bracket, two first transmission rollers are rotatably connected between the two side support uprights, a first transmission belt is installed between the outer walls of the two first transmission rollers, a front end of one of the first transmission rollers is fixedly connected to a first pulley, a first motor assembly is installed on one side of the rear end face of one of the side support uprights, an output end of the first motor assembly is fixedly connected to a second pulley, two transmission belts are installed between the first pulley and the second pulley, and the two side support uprights are provided with a plurality of blocking plates corresponding to the buffer support mechanism on a side away from each other.

[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 the other first transmission roller, the transmission of the first transmission belt is realized, and the bagged crops can be continuously placed on the first transmission belt, and the position can be adjusted by moving.

[0014] Furthermore, limiting plates corresponding to the top connecting frame plates are provided on both sides of the centers of the two side supporting vertical plates.

[0015] Through the above technical solution, the limiting plates provide a limiting effect when the two side support vertical plates move up and down, thereby 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, and two return springs are provided at the bottom of the two sliding blocks.

[0017] Through the above technical solution, during normal transmission, the first conveyor belt is supported by the rotating first support roller and rubber sleeve. When bagged crops are subsequently stacked, the crops press multiple first support rollers and then the return spring corresponding to the pressure of the sliding block is used to realize the lowering of the overall buffer support mechanism, thereby increasing the contact area between the packaging bag and the first pulley, and preventing the crops at the bottom from being damaged due to greater pressure.

[0018] Furthermore, the lifting drive mechanism includes an extension plate fixedly connected to one side of the bottom bracket, the front and rear ends of the top of the extension plate are fixedly connected to an L-shaped support vertical plate, the two L-shaped support vertical plates are fixedly connected to a group of fixing sleeves on the side close to each other, one side of the two L-shaped support vertical plates is fixedly connected to a U-shaped limit seat, a lifting hydraulic cylinder is fixedly connected between the two groups of fixing sleeves and the extension plate, the tops of the two lifting hydraulic cylinders are fixedly connected to support columns, the tops of the two support columns are installed with sprocket assemblies, transmission chains are installed on the two sprocket assemblies, one end of the two transmission chains is fixedly connected to a fixing part and the first transmission mechanism, the other end of the two transmission chains is fixedly connected to an L-shaped sliding plate, and a plurality of third bolt assemblies are installed on the two L-shaped sliding plates.

[0019] Through the above technical solution, after the crops are placed on the second transmission mechanism, the two lifting hydraulic cylinders simultaneously push the corresponding support columns and sprocket assemblies to rise. Since one end of the transmission chain is fixed by the fixing part, the other end of the transmission chain will rise as the sprocket assembly rises, thereby driving the two L-shaped sliding plates to slide upward in the corresponding U-shaped limit seats, thereby driving the entire second transmission mechanism and the bagged crops to rise, and stopping when the first conveyor belt rises to the same level as the second conveyor belt.

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

[0021] Through the above technical solution, when transporting bagged crops, the 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 and drives the third transmission roller to drive, and cooperates with the support of the second transmission roller to realize the transmission of the second conveyor belt. After the bagged crops contact one end of the second conveyor belt, they are driven onto the second conveyor belt and supported by multiple second support rollers.

[0022] Furthermore, the diameter of the second transport roller is greater than the diameter of the third transport roller.

[0023] Through the above technical solution, the upper surface of the entire second conveyor belt is made into an inclined structure, thereby facilitating easier transmission of bagged crops onto the second conveyor belt.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention designs a bidirectional drive mechanism and a first transmission mechanism. When crops are stacked, the bidirectional hydraulic cylinder assembly pushes the first output rod and the second output rod out at the same time. The first output rod starts to push the two connecting frame plates and the two tensioning roller assemblies to rise, thereby reducing the tension of the first transmission belt. The second output rod pushes the entire connecting frame mechanism to start descending, thereby achieving the descent of the connecting bottom frame, the two side support frame rods and the multiple adjustment rods. At this time, the two sliding blocks in the multiple buffer support mechanisms are pressed down by the bagged crops and compress the corresponding return springs. The bottom of the stacked crops contacts the relaxed first pulley and the multiple rubber sleeves, thereby greatly increasing the contact area between the packaging bag and the first pulley, thereby preventing the crops at the bottom from being damaged due to the large pressure; (2) The present invention designs a lifting drive mechanism and a second transmission mechanism, which can effectively reduce the operating intensity of handling. At the same time, in conjunction with the transmission of the first transmission mechanism, the overall device can realize the functions of lifting, transporting, picking up and transmitting crops, thereby greatly improving the scope of application of the device.

[0041] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, 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 intended to limit the present invention.

[0042] like Figures 1-6 and Figure 10As shown, a quick pick-up and drop device for agricultural product logistics storage in this embodiment includes a bottom bracket 1, a two-way driving mechanism 2 is fixedly connected between the front end and the rear end of the top center of the bottom bracket 1, the two-way driving mechanism 2 includes two groups of supporting angle steels 201, and mounting fixing plates 203 are placed on the tops of the two groups of supporting angle steels 201. A plurality of first bolt assemblies 202 are passed through the bottom bracket 1 and the two groups of supporting angle steels 201 and the two mounting fixing plates 203. The centers of the two mounting fixing plates 203 are fixedly connected with a two-way hydraulic cylinder assembly 204. The tops and bottoms of the two two-way hydraulic cylinder assemblies 204 are respectively slidably connected with 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 the top connecting rod 206. The connecting frame plate 207 and the two top connecting frame plates 207 are both provided with tensioning roller assemblies 208 at both ends. When the crops are stacked, the bidirectional hydraulic cylinder assembly 204 pushes the first output rod 205 and the second output rod 206 out at the same time. The first output rod 205 starts to push the two connecting frame plates 207 and the two tensioning roller assemblies 208 to rise, and the second output rod 206 pushes the entire connecting frame mechanism 3 to start descending, thereby reducing the tension of the first conveyor belt 403 and enabling the buffer support mechanism 5 to descend. Since the stroke between the connecting frame mechanism 3 and the bottom bracket 1 is small, after the connecting frame mechanism 3 descends and contacts the bottom bracket 1, the connecting frame mechanism 3 stops moving, and at this time the second output rod 206 continues to rise and lift up.

[0043] like Figure 1-Figure 7 As shown, the bottom output end of the bidirectional drive mechanism 2 is fixedly connected to a connecting frame mechanism 3, and the connecting frame mechanism 3 includes a connecting base frame 301, and the front and rear ends of the top of the connecting base frame 301 are fixedly connected to side support frame rods 302, and the tops of the two side support frame rods 302 are installed with multiple fixing ears 303, and multiple adjustment rods 304 are installed between the corresponding fixing ears 303 between the two side support frame rods 302, and second bolt assemblies 305 are provided between the two ends of the multiple adjustment 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 frame rods 302 to descend through the connecting base frame 301, and then drive the multiple adjustment rods 304 to descend, thereby releasing the support for the multiple buffer support mechanisms 5.

[0044] like Figures 1-11As shown, a first transmission mechanism 4 is fixedly connected between the two ends of the top of the bottom bracket 1, and 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, and a first transmission belt 403 is installed between the outer walls of the two first transmission rollers 402, and a first pulley 404 is fixedly connected to the front end of one of the first transmission rollers 402, and a first motor assembly 405 is installed on one side of the rear end face of one of the side support vertical plates 401, and a second pulley 406 is fixedly connected to the output end of the first motor assembly 405, and two transmission belts 407 are installed between the first pulley 404 and the second pulley 406, and the two side The supporting uprights 401 are provided with a plurality of blocking plates 408 corresponding to the buffer support mechanism 5 on the sides 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 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, and the bagged crops can be continuously placed on the first transmission belt 403, and the position can be adjusted by moving. Limiting plates corresponding to the top connecting frame plate 207 are provided on both sides of the center of the two side supporting uprights 401. The limiting plates provide a limiting effect when the two side supporting uprights 401 move up and down, thereby ensuring the stability of the movement.

[0045] like Figures 1-11 As shown, a plurality of buffer support mechanisms 5 are installed on the first transmission mechanism 4, and the buffer support mechanism 5 includes two sliding blocks 501, and a first support roller 502 is rotatably connected between the two sliding blocks 501. The outer wall of the first support roller 502 is sleeved with a rubber sleeve 503, and two return springs 504 are provided at the bottom of the two sliding blocks 501. During normal transmission, the first transmission belt 403 is supported by the rotating first support roller 502 and the rubber sleeve 503. When the bagged crops are subsequently stacked, the crops press the multiple first support rollers 502 and then the return springs 504 corresponding to the pressure of the sliding blocks 501 are used to realize the downward movement of the entire buffer support mechanism 5, thereby increasing the contact area between the packaging bag and the first pulley 404, and avoiding damage to the crops at the bottom due to greater pressure. The rear end drive component 6 and the front end steering component 7 are respectively installed on both sides of the bottom bracket 1.

[0046] like Figures 1-13As shown, one side of the bottom bracket 1 is fixedly connected to a lifting drive mechanism 8, and the lifting drive mechanism 8 includes an extension plate 801 fixedly connected to one side of the bottom bracket 1, and the front and rear ends of the top of the extension plate 801 are fixedly connected to L-shaped support vertical plates 802, and the two L-shaped support vertical plates 802 are fixedly connected to a group of fixing sleeves 803 on the side close to each other, and one side of the two L-shaped support vertical plates 802 is fixedly connected to a U-shaped limit seat 804, and a lifting hydraulic cylinder 805 is fixedly connected between the two groups of fixing sleeves 803 and the extension plate 801, and the tops of the two lifting hydraulic cylinders 805 are fixedly connected to support columns 806, and the tops of the two support columns 806 are installed with sprocket assemblies 807, and the two sprocket assemblies 807 are installed with transmission chains 808, and one end of the two transmission chains 808 and the first The transmission mechanisms 4 are fixedly connected with fixing parts 809, and the other ends of the two transmission chains 808 are fixedly connected with L-shaped sliding plates 810. A plurality of third bolt assemblies 811 are installed on the two L-shaped sliding plates 810. After the crops are placed 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 part 809, the rise of the sprocket assembly 807 will drive the other end of the transmission chain 808 to rise, thereby driving the two L-shaped sliding plates 810 to slide upward in the corresponding U-shaped limit seats 804, thereby driving the entire second transmission mechanism 9 and the bagged crops to rise, and stop when the first transmission belt 403 rises to the same horizontal plane as the second transmission belt 905.

[0047] like Figures 1-15 As shown, a second transmission mechanism 9 is installed on the lifting drive mechanism 8, and the second transmission mechanism 9 includes two side brackets 901 installed on the lifting drive mechanism 8, and a second transmission roller 902, a third transmission roller 903 and a plurality of second support rollers 904 are rotatably connected between the two side brackets 901. A second transmission belt 905 is provided between the second transmission roller 902 and the third transmission roller 903. The front end of the third transmission roller 903 is fixedly connected to the front end surface of the side bracket 901 with a second motor assembly 906. When transporting bagged crops, the crops are moved to the second transmission roller 906. One side of the mechanism 9 is placed on the ground. At this time, the second motor assembly 906 is started and then drives the third transmission roller 903 to drive, and cooperates with the support of the second transmission roller 902 to realize the transmission of the second transmission belt 905. After the bagged crops touch one end of the second transmission belt 905, they are driven onto the second transmission belt 905 and supported by multiple second support rollers 904. The diameter of the second transmission roller 902 is larger than the diameter of the third transmission roller 903, so that the upper surface of the entire second transmission belt 905 has a slope structure, which makes it easier for the bagged crops to be transferred to the second transmission belt 905.

[0048] The working principle of this embodiment is as follows. When transporting bagged crops, the crops are moved to one side of the second conveying mechanism 9 and placed on the ground. At this time, the second motor assembly 906 is started and drives the third conveying roller 903 to drive, and cooperates with the support of the second conveying roller 902 to realize the transmission of the second conveyor belt 905. After the bagged crops touch one end of the second conveyor belt 905, they are driven onto the second conveyor belt 905 and supported by multiple second support rollers 904. Then, the two lifting hydraulic cylinders 805 simultaneously push the corresponding support column 806 and sprocket assembly 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 rise, thereby driving the two L-shaped sliding plates 810 to slide upward in the corresponding U-shaped limit seat 804, thereby driving the entire second conveying mechanism 9 and the bagged crops to rise. When the first conveyor belt 403 rises to the same level as the second conveyor belt 905, it stops;

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

[0050] When bagged products are stacked, they can be lifted or lowered in a stacking manner of two or more bags, and then transferred to the first conveyor belt 403. After the transfer is completed, the bidirectional hydraulic cylinder assembly 204 pushes the first output rod 205 and the second output rod 206 out at the same time, and the first output rod 205 begins to push the two connecting frame plates 207 and the two tensioning roller assemblies 208 to rise, thereby reducing the tension of the first conveyor belt 403. At the same time, the second output rod 206 pushes the entire connecting frame mechanism 3 to start descending, thereby achieving the descent of the connecting bottom frame 301, the two side support frame rods 302 and the multiple adjustment rods 304. At this time, the two sliding blocks 501 in the multiple buffer support mechanisms 5 have no adjustment rods. The support 304 will be pressed down by the bagged crops and compress the corresponding return spring 504. The bottom of the stacked crops will contact the relaxed first pulley 404 and multiple rubber sleeves 503, which can greatly increase the contact area between the packaging bag and the first pulley 404, and prevent the crops at the bottom from being damaged due to the large pressure. After the entire device moves to the designated position to complete unloading, the two-way hydraulic cylinder assembly 204 pulls the first output rod 205 and the second output rod 206 to reset. At this time, multiple adjustment rods 304 rise to continue to support the multiple buffer support mechanisms 5, and the two tensioning roller assemblies 208 descend and reset, continuing to support the first conveyor belt 403, so that the first conveyor belt 403 is tightened.

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