Technical Field
[0001] This invention relates to the field of tea-picking machine technology, and in particular to a tea-picking netting machine. Background Technology
[0002] Japanese Patent No. JP6030500B2 discloses a winding device for covering materials such as turf cloth directly covering tea ridges. This is a novel winding and unfolding device capable of particularly efficient and neat winding. To achieve multi-functionality in agricultural machinery, it is typically connected to the power unit of a tea-picking machine to create a tea-picking netting machine. However, this winding device still has the following drawbacks and shortcomings:
[0003] Single rolls of covering netting are generally difficult to precisely fit tea ridges of different lengths. Therefore, single rolls of covering netting are usually designed with a certain margin. After the covering machine has laid a tea ridge, the covering netting needs to be cut. The cut covering netting can only fit that section of tea ridge. When recycled, it can only be used to cover that section of tea ridge. Therefore, the existing netting rolls are difficult to recycle efficiently.
[0004] In addition, when collecting the covering nets covering the tea ridges, one end of the net must be fixed to a roller beforehand, and then the roller is rotated to collect the nets. The process is complicated and labor-intensive. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a tea-picking and covering netting machine. A detachable roller allows for the complete discarding of the roller and remaining covering netting after covering, ensuring the integrity of the covering netting. Simultaneously, a clamping mechanism limits the rotation of the remaining covering netting, avoiding the problem of inconsistent covering caused by shearing the covering netting.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a tea-picking and netting machine, comprising a walking part and a netting frame disposed behind the walking part;
[0007] The mesh laying frame is equipped with a detachable roller, and a covering net is wound on the roller;
[0008] The mesh laying frame has symmetrical guide grooves on both sides for the roller to slide. The bottom of the mesh laying frame is rotatably provided with a separation plate that connects to the guide grooves. The separation plate is connected to a first push rod.

[0009] The roller is symmetrically provided with guide blocks at both ends and clamping plates that slide with the guide blocks and clamp the outer wall of the wire mesh frame. The two ends of the clamping plates are slidably connected to the guide blocks through guide rods.
[0010] The reel is provided with a first clutch that cooperates with the guide block. The first clutch is provided with several pin holes. The guide block is provided with a locking pin that cooperates with the guide rod. After the guide rod slides, it drives the locking pin to slide so that the guide block and the reel become a whole, thereby limiting the cover net remaining on the reel by the clamp.
[0011] In the above scheme, preferably, the guide block is provided with a guide hole adapted to the guide rod, and a first spring is provided between the clamping plate and the guide block.
[0012] In the above scheme, preferably, the first clutch is slidably mounted on the reel, the guide block is rotatably mounted on the first clutch, and a tension spring is provided between the first clutch and the reel.
[0013] In the above scheme, preferably, the guide rod is provided with a concave hole that cooperates with the locking pin, the guide block is provided with a receiving cavity that cooperates with the locking pin, and a second spring is provided between the locking pin and the receiving cavity.

[0017] In the above scheme, preferably, the slide rail includes a driving surface, and the sliding part is provided with a pressing surface that presses against the driving surface.
[0018] In the above scheme, preferably, the separation plate is provided with a rotating shaft, the rotating shaft is provided with a rocker arm, one end of the rocker arm is fixed to the rotating shaft, and the other end is connected to the first push rod.
[0019] In the above scheme, preferably, the clamping plate is slidably provided with extension plates at both ends, and the guide rod is provided on the extension plates.
[0020] The beneficial effects of this invention are:
[0021] 1. High efficiency recycling and reuse: After discarding the roll, the remaining amount of the covering net can be directly adapted to tea ridges of different lengths by limiting the clamps, reducing cutting waste;

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See also Figures 1-7 .
[0032] A tea-picking and covering netting machine includes a walking part 1 and a netting frame 2 located behind the walking part 1. The netting frame 2 is located behind the walking part 1 in the walking direction. A blade for cutting tea leaves is located in front of the walking part 1. After the tea leaves are cut, a covering net is laid on the tea ridge by the netting frame 2.
[0033] The netting frame 2 is equipped with a detachable roller 201, on which a covering net 200 is wound, i.e., the covering net 200 is rolled up and stored, and placed on the netting frame 2, so that the covering net 200 is laid and stored by the netting frame 2.
[0034] The scroll 201 has symmetrically arranged shaft cores 7 at both ends. The shaft cores 7 are hexagonal shafts. A first clutch 3 is slidably arranged on the shaft cores 7. The center of the first clutch 3 is provided with a hexagonal hole that is adapted to the hexagonal shaft.
[0035] A tension spring 302 is provided between the first clutch 3 and the end wall of the reel 201. In the initial state, the first clutch 3 is pulled by the tension spring 302 and is located on the side close to the end wall of the reel 201. The end of the first clutch 3 away from the reel 201 is provided with a clutch tooth, and the outer wall of the end close to the reel 201 is provided with a locking groove 303. The locking groove 303 is an annular groove, and a guide block 205 is rotatably provided on the locking groove 303. That is, the guide block 205 is rotatably locked onto the first clutch 3 through the locking groove 303.
[0036] The mesh laying frame 2 is symmetrically provided with guide grooves 202 on both sides for the sliding of the roll 201. Specifically, the guide groove 202 is a vertical long groove with an open top, and the groove width is adapted to the outer circle of the first clutch 3. The two ends of the roll 201 are slidably inserted into the guide groove 202 through the first clutch 3 to complete the assembly of the roll and the mesh laying frame 2. A connecting plate 8 is provided at the upper end of the guide groove 202. The connecting plate 8 is detachably fixedly connected to the mesh laying frame 2. When the roll 201 is installed, the connecting plate 8 is removed and then installed. After installation, the connecting plate 8 is resealed to fix the upper opening of the guide groove 202.
[0037] The guide groove 202 is symmetrically provided with slide rails 214 on both sides of the end face away from the scroll 201, such as... Figures 2-4 As shown, the upper section of the slide rail 214 is straight, while the lower section is inclined outwards towards the side away from the spool 201 to form a driving surface 216. The guide block 205 is provided with a sliding part 215 that cooperates with the slide rail 214. That is, when the first clutch 3 slides into the guide groove 202, the sliding part 215 on the guide block 205 contacts and cooperates with the slide rail 214. The sliding part 215 is provided with a pressing surface 217 that presses against the driving surface 216. When the pressing surface 217 on the sliding part 215 slides and cooperates with the driving surface 216, it can drive the guide block 205 to slide away from the spool 201, thereby synchronously driving the clutch teeth of the first clutch 3 to slide away from the spool 201.
[0038] The netting frame 2 has a second clutch 4 on any side that cooperates with the first clutch 3. The second clutch 4 is located on the side of the guide groove 202 away from the roller 201 and is coaxial with the arc center of the lower section of the guide groove 202. When the guide block 205 slides down on the slide rail 214, the first clutch 3 slides into the arc groove at the lower end of the guide groove 202, so that the clutch teeth are engaged with the clutch teeth of the second clutch 4, thus achieving engagement.
[0039] The netting frame 2 is equipped with a drive shaft 5, which is a hexagonal shaft. The second clutch 4 is slidably mounted on the drive shaft 5. The drive shaft 5 is connected to a drive motor. When the drive motor starts, the drive shaft 5 can drive the second clutch 4 to rotate, thereby synchronously driving the first clutch 3, which is engaged with it, to rotate. Furthermore, it drives the roller 201 to rotate, realizing the laying and storage of the cover net 200. The second clutch 4 is provided with a hexagonal hole, and the outer wall of the second clutch 4 is provided with a slot. The slot is provided with a clutch plate 601 that rotates with it. The netting frame 2 is equipped with a second push rod 6. The push rod end of the second push rod 6 is fixedly connected to the clutch plate 601, thereby driving the second clutch 4 to slide relative to the first clutch 3, realizing engagement and disengagement with it, without affecting the transmission cooperation between the drive shaft 5 and the second clutch 4.
[0040] The bottom of the mesh laying frame 2 is rotatably provided with a separation plate 203 that connects with the guide groove 202. The bottom arc of the guide groove 202 is set on the separation plate 203. When the separation plate 203 rotates, the bottom of the guide groove 202 can be opened, thereby allowing the two ends of the roll 201 to slide downwards and separate from the mesh laying frame 2.
[0041] A rotating shaft 9 is provided on one side of the separating plate 203. The rotating shaft 9 is rotatably mounted on the plate at the bottom of the netting frame 2. One end of the rotating shaft 9 passes through the wall of the netting frame 2 and is fixed with a rocker arm 901. One end of the rocker arm 901 is fixed to the rotating shaft 9, and the other end is rotatably connected to the push rod end of the first push rod 204. After the first push rod 204 pushes the rocker arm 901 to rotate, the separating plate 203 rotates and opens the bottom of the guide groove 202, making the bottom of the guide groove 202 open. Then, the second push rod 6 drives the second clutch 4 to slide, so that it disengages from the first clutch 3, and the roll 201 slides out of the netting frame 2 from the bottom of the guide groove 202, realizing the separation of the roll 201 from the netting frame 2.
[0042] To ensure that the remaining covering net 200 is fixed relative to the main body of the roll 201 and not pulled after the roll 201 is detached from the netting frame 2, in this embodiment, clamping plates 206 that clamp the outer wall of the roll 201 in the axial direction are slidably arranged on the guide blocks 205 at both ends of the roll 201. Retractable extension plates 10 are symmetrically arranged at both ends of the clamping plates 206. Guide rods 207 are fixed on the extension plates 10. The guide rods 207 are arranged through the guide blocks 205, so that the two ends of the clamping plates 206 are slidably connected to the guide blocks 205 through the guide rods 207.
[0043] The first clutch 3 is provided with a plurality of pin holes 301, which are evenly arranged in the locking groove 303 and penetrate through the middle hole of the first clutch 3. The guide block 205 is vertically slidably provided with a locking pin 208 that drives and cooperates with the guide rod 207. Figure 3As shown, the guide rod 207 is provided with a concave hole 211 that mates with the upper end of the locking pin 208, and the guide block 205 is provided with a receiving cavity 212 that mates with the lower end of the locking pin 208. That is, initially, the lower end of the locking pin 208 is placed in the receiving cavity 212, and the upper end is abutted against the concave hole 211. The bottom of the receiving cavity 212 is provided with a sliding hole, and the lower end of the locking pin 208 is placed in the sliding hole. A second spring 213 is provided between the locking pin 208 and the bottom of the lower end of the receiving cavity 212.
[0044] The guide block 205 is provided with a guide hole 209 that is adapted to the guide rod 207. A first spring 210 is provided between the clamping plate 206 and the guide block 205. Specifically, the two ends of the first spring 210 are connected to the guide block 205 and the extension plate 10, respectively.
[0045] When the guide rod 207 is on the netting frame 2, the clamping plate 206 limits its position against the outer wall of the netting frame 2, thereby placing the upper end of the locking pin 208 in a position corresponding to the concave hole 211. When the roll 201 is separated from the netting frame 2, the clamping plate 206 is released from its limiting position. After the guide rod 207 slides relative to the guide block 205, it drives the locking pin 208 to compress the second spring 213 and then slides to insert the lower end of the locking pin 208 into any pin hole 301 of the first clutch 3, thereby making the guide block 205 and the roll 201 a whole. At this time, the clamping plate 206 and the roll 201 are in a relatively fixed state, and the remaining cover net 200 on the roll 201 is limited by the clamping plate 206, thereby preventing the remaining cover net 200 from continuing to extend.
[0046] Using a tea-picking netting machine as described above:
[0047] The roller 201 and the covering net 200 wound on it are rolled up and inserted into the guide groove 202 through the outer wall of the first clutch 3 at both ends, and the sliding part 215 of the guide block 205 is made to contact and cooperate with the slide rail 214. At this time, the clamping plate 206 is placed outside the net laying frame 2 and slides in contact with its outer wall.
[0048] After the guide block 205 abuts against the driving surface 216 through the pressing surface 217 on the sliding part 215, it causes the first clutch 3 to slide away from the end of the roll 201. Then the clutch teeth on the first clutch 3 mesh with the clutch teeth on the second clutch 4, the walking part 1 of the tea picking machine moves, the drive motor starts the drive shaft 5 to rotate, and the covering net 200 is covered on the tea ridges after picking by the rotation of the roll 201.
[0049] When the tea ridge is reached, the drive motor stops. At the same time, the second push rod 6 starts to slide the second clutch 4 away from the first clutch 3, so that the two are disengaged. Then the first push rod 204 drives the separation plate 203 to rotate, so that it opens the bottom of the guide groove 202. Furthermore, the roller 201, together with the remaining covering net 200, is completely separated from the net laying frame 2.
[0050] Subsequently, the clamping plate 206 slides to the guide block 205 via the first spring 210, and the guide rod 207 drives the locking pin 208 to slide downward so that it engages with the pin hole 301 on the first clutch 3, thereby locking the roll 201 and the guide block 205 in the circumferential direction, i.e., they cannot rotate relative to each other. The entire roll 201 falls to the end of the tea ridge, and the clamping plate 206 limits the remaining covering net 200 so that it remains rolled up on the roll 201.
[0051] When the covering net 200 needs to be stored after being laid out, simply reinstall the roll 201 at the end of the tea ridge into the guide groove 202 and engage it with the second clutch 4, then reverse the drive motor to store the covering net 200.
[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
