DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1As shown, the utility model provides a locking hook 51 device of a silage baling and wrapping machine, comprising: a movable bin 1, a fixed bin 2, a bracket unit 3, a cylinder unit 4 and a locking unit 5, the movable bin 1 and the fixed bin 2 are hinged, the bracket unit 3 is hingedly arranged on the fixed bin 2, one end of the cylinder unit 4 is arranged on the movable bin 1, and the other end is arranged on the bracket unit 3, one end of the locking unit 5 is hooked on or detached from the movable bin 1, and the other end is connected to the bracket unit 3, when the cylinder unit 4 is extended, a force is applied to the bracket unit 3, so that the bracket unit 3 is pushed to rotate around its axis and drive the locking unit 5 thereon to tilt, so that the hook lock end of the locking unit 5 is unlocked from the hooked state to the detached state of the movable bin 1. The movable bin 1 and the fixed bin 2 can be locked by the locking unit 5, so that the bin door formed between the movable bin 1 and the fixed bin 2 is tightly closed, avoiding the problem of material leakage on both sides of the bin door, and the locking unit 5 between the movable bin 1 and the fixed bin 2 can be automatically unlocked by extending the cylinder unit 4, thereby improving its convenience. In addition, the lock structure in the present device is simple, easy to use, and low in cost. It should be noted that when unlocking, since the cylinder unit 4 will give a force to the bracket unit 3 when extending, the force can tilt the bracket unit 3, that is, the force can drive the bracket unit 3 to rotate around its axis, thereby driving the locking unit 5 thereon to tilt, and the hook lock end of the locking unit 5 is detached from the hook of the movable bin 1, thereby achieving the purpose of unlocking. During the locking process, the cylinder unit 4 needs to give a pulling force to the bracket unit 3 when it contracts. The pulling force can pull the bracket unit 3 to rotate around its axis, thereby driving the locking unit 5 thereon to reset, and the hook locking end of the locking unit 5 is disengaged from the movable compartment 1 to hooked, thereby achieving the purpose of locking.

[0024] In one embodiment, a limit plate 6 is further included, which is arranged on the fixed bin 2 and below the bracket unit 3 to limit the bracket unit 3 from rotating at a predetermined angle. When the hook lock end of the locking unit 5 is detached from the movable bin 1, the bracket unit 3 abuts against the limit plate 6. The bracket unit 3 abuts against the limit plate 6, thereby providing a supporting force to the cylinder unit 4, so that the cylinder unit 4 can subsequently extend with the support point of the limit plate 6 and lift up the movable bin 1 to open the bin door, so that the lock hook 51 is lifted and detached from the movable bin 1.

[0025] In one embodiment, the locking unit 5 includes a lock hook 51 and an elastic element 52, one end of the lock hook 51 is arranged on the bracket unit 3, one end of the elastic element 52 is arranged on the fixed bin 2, and the other end is arranged on the lock hook 51. In the unlocked state, the cylinder unit 4 extends to give a force to the bracket unit 3 that is greater than the tension given to the lock hook 51 by the elastic element 52. During locking, the self-weight of the lock hook 51 is less than the tension of the elastic element 52, so that the lock hook 51 is hooked on the movable bin 1. The elastic element 52 can further lock the lock hook 51 and the locking sleeve 7 when locking between the movable bin 1 and the fixed bin 2, and can provide a tensioning force for the lock hook 51 to lock the movable bin 1, so as to avoid the problem of the lock hook 51 temporarily detaching from the movable bin 1 due to the compression of the movable bin 1 and the fixed bin 2 when the wrapping material in the bin is wrapped. Optionally, the elastic element 52 is a tension spring.

[0026] In one embodiment, a locking sleeve 7 is provided in a direction perpendicular to the movable bin 1. In the locked state, the hook lock end of the locking unit 5 is hooked on the locking sleeve 7. It should be noted that in the locked state, the locking hook 51 on the locking unit 5 is hooked on the locking sleeve 7, and at this time, the cylinder unit 4 does not perform any work. When the movable bin 1 and the fixed bin 2 are in an open state, the locking hook 51 and the locking sleeve 7 are separated, the cylinder unit 4 contracts itself and drives the bracket unit 3 to rotate clockwise, so that the locking hook 51 also rotates clockwise with the bracket unit 3, and the locking hook 51 gradually approaches the locking sleeve 7 until the cylinder unit 4 contracts. Due to the friction between the locking hook 51 and the locking sleeve, the locking hook 51 and the locking sleeve cannot be locked, and the tension given by the elastic element 52 is greater than the friction between the locking hook 51 and the locking sleeve, and the locking hook 51 is hooked and locked on the locking sleeve 7, thereby realizing automatic locking of the movable bin 1 and the fixed bin 2.

[0027] In one embodiment, the locking unit 5 further includes an inverted and mirror-image L-shaped support plate 53, which is disposed on the fixed bin 2, and is disposed below the bracket unit 3, and one end of the elastic element 52 is connected to the support plate 53. The support plate 53 can be used to place the elastic element 52 and the locking hook 51 on the same horizontal line, which is beneficial to the elastic stretching of the elastic element 52.

[0028] In one embodiment, the lock hook 51 includes a connecting portion 511 and a locking portion 512 connected to each other. One end of the connecting portion 511 is connected to the bracket unit 3, and the other end is connected to the locking portion 512. The locking portion 512 is hooked on the locking sleeve 7 on the movable bin 1. The connecting portion 511 extends along its length and is straight, and the locking portion 512 is bent at a preset angle. Optionally, the locking portion 512 is a hook-shaped structure so that the locking sleeve 7 can be hooked to achieve locking. In addition, the locking portion 512 is bent at a preset angle to facilitate cooperation with the locking sleeve 7. In addition to the hook-lock cooperation between the locking portion 512 and the locking sleeve 7, a buckle can be set at the end of the lock hook 51, that is, the locking portion 512 has a buckle, and a clamping sleeve is set on the locking sleeve 7, so that locking can also be achieved.

[0029] In one embodiment, the bracket unit 3 includes a rotating shaft 31 and a bracket seat 32. The bracket seat 32 is connected to the fixed bin 2 via the rotating shaft 31. One end of the cylinder unit 4 and the locking unit 5 are respectively connected to the bracket seat 32. The bracket unit 3 can be rotated by the rotating shaft 31. When unlocking, the cylinder unit 4 drives the bracket unit 3 to rotate when it is extended, and the lock hook 51 in the locking unit 5 on the bracket unit 3 also rotates accordingly, so that the lock hook 51 leaves the locking sleeve 7, that is, unlocking is achieved. When locking, the cylinder unit 4 contracts and drives the bracket unit 3 to rotate, and the lock hook 51 in the locking unit 5 on the bracket unit 3 also rotates accordingly. The lock head 512 is bent at a preset angle to facilitate the hook lock, so that the lock hook 51 is close to the locking sleeve 7 until the lock hook 51 hooks the locking sleeve 7 to complete the locking.

[0030] In one embodiment, a first mounting position 321 and a second mounting position 322 are adjacently provided on the bracket seat 32, and one end of the cylinder unit 4 and the locking unit 5 are connected to the first mounting position 321 and the second mounting position 322 in sequence, and the first mounting position 321 is located higher than the second mounting position 322. The cylinder unit 4 and the locking unit 5 are fixed by the first mounting position 321 and the second mounting position 322, respectively, that is, the first mounting position 321 is used to fix and connect one end of the cylinder 41, and the second mounting position 322 is used to fix and connect one end of the locking hook 51, so that the cylinder unit 4 and the locking unit 5 do not interfere with each other, and it is also convenient for the cylinder unit 4 to push the bracket unit 3 to rotate.

[0031] In one embodiment, the cylinder unit 4 includes a cylinder 41 and a fixed column 42. One end of the cylinder 41 is connected to the bracket unit 3, and the other end is connected to the fixed column 42. The fixed column 42 is arranged on the movable bin 1. The position of the cylinder 41 is limited within a fixed range of motion by the fixed column 42 and the bracket unit 3. The bracket unit 3 is driven to rotate counterclockwise or clockwise by the extension and contraction of the cylinder 41, so that the bracket unit 3 drives the hook lock in the locking unit 5 to rotate counterclockwise or clockwise, thereby realizing the unlocking or locking of the locking sleeve 7 by the lock hook 51.

[0032] In one embodiment, the elastic element 52 includes an elastic member 521 and a connecting member 522 connected to each other, one end of the elastic member 521 is connected to the lock hook 51, and one end of the connecting member 522 is connected to the fixed bin 2. The elastic member 521 is connected by the connecting member 522, so that the length of the elastic member 521 can be connected to the lock hook 51, and there is a buffer between the elastic member 521 and the connecting member 522, so that when a gap appears between the movable bin 1 and the fixed bin 2, the elastic member 521 will not be stretched sharply, thereby avoiding affecting the life of the elastic member 521.

[0033] In one embodiment, a bin body (not shown) is further included, and the movable bin 1 and the fixed bin 2 are part of the bin body and are located on one side of the bin body. The bin body is used to hold materials, and the bin body can be locked by a locking unit 5 between the movable bin 1 and the fixed bin 2. When the bin body has processed the materials inside, the processed materials are released by opening the movable bin 1.

[0034] In summary, after the locking hook device of the utility model is installed, the problem of the bin door not being tightly closed and material leakage on both sides no longer occurs when the silage baling and film wrapping machine performs baling and film wrapping operations.

[0035] The working principle of the lock hook device of the utility model is as follows: when the silage baling and wrapping machine is performing the baling and wrapping operation, the movable bin 1 is in a closed state, and the lock hook 51 is hooked on the locking sleeve 7. When the wrapping is completed, when the oil cylinder 41 is extended, the oil cylinder 41 on the oil cylinder unit 4 applies a force to the support seat 32 of the support unit 3, and the force is greater than the total gravity of the support seat 32 and the lock hook 51, and greater than the pulling force of the elastic element 52, so that the support seat 32 can be driven to rotate around its rotating shaft 31, that is, it can push the support seat 32 to rotate and drive the lock hook 51 thereon to tilt, so that the hook lock end of the lock hook 51 is lifted upward, disengaged from the locking sleeve 7, thereby achieving unlocking. At this time, the oil cylinder unit 4 is still extending, until the support seat 32 is pushed to run to contact the limit plate 6, the lock hook 51 stops tilting, and the oil cylinder 41 continues to extend with the limit plate 6 as the fulcrum, and the movable bin 1 is opened to release the straw bale. After the straw bale is transported away, the oil cylinder 41 contracts to generate a pulling force on the bracket seat 32, which enables the bracket seat 32 to rotate around its rotating shaft 31, and the locking hook 51 on the bracket seat 32 droops until the oil cylinder 41 is completely contracted and reset, the movable bin 1 is closed, and the elastic element 52 pulls the locking hook 51 downward, so that the locking hook 51 is hooked on the locking sleeve 7, thereby achieving locking, that is, completing a working cycle of the locking hook 51 device.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
