Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a jujube dropping device. Background Art

[0002] Jujube, also known as red dates and jujube, has been listed as one of the "five fruits" (peach, plum, plum, apricot, jujube) since ancient times and has a long history. The most prominent feature of jujube is its high vitamin content. A clinical study abroad showed that patients who continuously ate jujube recovered more than three times faster than those who simply took vitamin pills. Therefore, jujube has the reputation of "natural vitamin pill". Jujube is a temperate crop with strong adaptability. Jujube is known as the "hardcore crop" and has the characteristics of drought and waterlogging resistance. It is the first choice for the development of water-saving forestry and fruit industry.

[0003] Harvesting is the last link in the field management of jujubes. If the harvest is not timely, the jujubes will be too mature, which will not only affect the storage resistance and product quality of the fruit, but also affect the yield in the next year. For example, the application publication number is CN109168623A, and the name is an invention patent for a branch-shaking jujube picking machine, which includes a shaking device, a connecting mechanism, a transmission mechanism, a motor system, a protective shell device, a main rod system, and a power supply system. The jujubes are separated from the jujube branches and dropped to the ground by shaking the jujube branches, thereby completing the jujube harvesting process. However, a jujube tree has many branches, and the shaking of each branch makes the working time in the jujube field too long, and the efficiency of dropping the jujubes is very low. In addition, the diameter of the branches is relatively thin, and directly shaking or hitting the branches can easily cause the branches to break and other damages. Therefore, it is necessary to design an efficient jujube dropping machine that does not affect the growth of the branches. Summary of the invention

[0004] In view of this, it is necessary to provide a jujube dropping device to solve the technical problem in the prior art that branches are easily broken or otherwise damaged when being hit or vibrated during the jujube dropping process.

[0039] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0040] See also Figure 1-Figure 6 The present invention provides a date dropping device, comprising a collision mechanism 1 and a driving mechanism 2;

[0041] The collision mechanism 1 is formed by a main fan member 11 and two secondary fan members 12 abutting against each other. The main fan member 11 includes a main fan shell 111, a main rotating member 112 built in the main fan shell 111, and a main push rod 113. The secondary fan member 12 includes a secondary fan shell 121, a secondary rotating member 122 built in the secondary fan shell 121, and a secondary push rod 123.

[0042] The main rotating member 112 and the secondary rotating member 122 abut against each other to form a propulsion unit 1121, and the driving mechanism 2 drives the propulsion unit 1121 to rotate back and forth on the inner walls of the main fan housing 111 and the secondary fan housing 121;

[0043] The main push rod 113 and the secondary push rod 123 are both slidably connected to the top of the propulsion unit 1121. When the propulsion unit 1121 rotates, it drives the main push rod 113 and the secondary push rod 123 away from or hits the tree trunk.

[0044] Specifically, the propulsion unit composed of the main rotating part 112 and the secondary rotating part 122 rotates under the drive of the driving mechanism 2, and drives the main pushing rod 113 and the secondary pushing rod 123 to repeatedly hit the tree trunk. The larger the diameter of the tree trunk, the stronger the stability, and the better the ability to resist pressure and injury. Compared with the method of directly shaking the branches, it can reduce damage to the branches and speed up the falling rate of the dates. It only needs the main pushing rod 113 and the secondary pushing rod 123 to hit the tree trunk. The vibration of the tree trunk will be transmitted to each branch. The mature dates on each branch will fall to the ground due to the influence of gravity, which is convenient for the staff to collect the dates in the later stage.

[0045] The main rotating member 112 and the secondary rotating member 122 are sequentially built into the bottom surfaces of the inner walls of the main fan shell 111 and the secondary fan shell 121, and with the trunk of the jujube tree for picking jujubes as the center, the main fan member 11 and the secondary fan member 12 abut against each other in turn to form a collision mechanism 1, so that the main rotating member 112 and the secondary rotating member 122 abut against each other to form a propulsion unit 1121, and the driving mechanism 2 drives the propulsion unit 1121 to make the main push rod 113 and the secondary push rod 123 move back and forth on the main fan shell 111 and the secondary fan shell 121 to hit the trunk.

[0046] Preferably, the inner diameter of the propulsion unit 1121 formed by the main rotating member 112 and the secondary rotating member 122 abutting against each other is larger than the diameter of the tree trunk. The main rotating member 112 and the secondary rotating member 122 cannot touch the tree trunk, thereby ensuring the normal rotation of the propulsion unit 1121.

[0047] In this embodiment, further, please refer to Figure 6 The upper part of the main fan shell 111 and the secondary fan shell 121 is provided with a groove slide 1111 facing the trunk. Specifically, there are three groove slides 1111. The main fan member 11 and each secondary fan member 12 have a groove slide 1111 and are centered on the trunk, in a diffuse line shape. The main function is to convert the rotation trajectory of the propulsion unit 1121 into a straight trajectory, ensuring that the direction of the main push rod 113 and the secondary push rod 123 on the groove slide 1111 is always the center of the impact on the trunk.

[0048] It should be noted that the surfaces where the main fan shell 111 and the secondary fan shell 121 are abutted and assembled with each other are provided with matching convex buckles 1112 and concave buckles 1211, so that the staff can quickly and accurately find the abutment points, abut the main fan shell 111 and the secondary fan shell 121 stably, and will not slide due to the smoothness of the abutment surfaces.

[0049] In this embodiment, further, please refer to Figure 4 The main push rod 113 and the secondary push rod 123 each include a rod head 1131, a rod body 1132 and a slider 1133. The rod head 1131 is fixedly connected to one end of the rod body 1132 facing the tree trunk. The slider 1133 is rotatably connected to the lower side of the rod body 1132. The rod body 1132 is slidably connected to the groove slide rail 1111 of the main fan housing 111 and the secondary fan member 12. Specifically, the rod body 1132 is divided into two parts, the upper part is slidably engaged in the groove slide rail 1111, and the lower part is provided with a round hole for rotatably connecting with the cylindrical bar 11331 of the slider 1133.

[0050] Preferably, the main push rod 113 and the secondary push rod 123 have the same shape and structural features, and rubber 11311 is added to the collision surface of the rod head 1131 hitting the tree trunk to play a role in buffering and protecting the tree trunk.

[0051] In this embodiment, further, please refer to Figure 5, the upper part of the main rotating member 112 and the secondary rotating member 122 is provided with an inclined rail 11212 for sliding the slider 1133. Specifically, the function of the inclined rail is to convert the rotational motion of the propulsion unit 1121 into motion in the linear direction of the inclined rail. One end of the slider 1133 is clamped and slidably connected to the inclined rail. As the inclined rail moves in the linear direction, the other end of the slider 1133 is rotatably connected to the rod body 1132. The rod body 1132 is deflected by the force of the slider 1133, but due to the existence of the groove rail 1111, the deflection of the rod body 1132 is blocked, thereby converting the deflection angle into an impact in the linear direction of the groove rail 1111.

[0052] In this embodiment, further, please refer to Figure 3 , and also includes a support mechanism 3, which includes a locking plate 31, a locking rope 32 and a support frame 33. The locking plate 31 is fixedly connected to the bottom of the main fan shell 111 and the secondary fan shell 121, and the support frame 33 is hinged to the bottom of the locking plate 31. Specifically, in order to facilitate the staff to carry it and to facilitate the staff to quickly change the jujube tree to pick jujubes, a simple field interlaced fixing method is selected for the fixing method of the device. The support frame 33 is hinged with the device to facilitate adapting to different soil scenes.

[0053] It should be noted that an annular groove 312 is provided on the upper surface of the restraining disk 31, and an annular protrusion 11211 provided on the lower surface of the main rotating member 112 and the secondary rotating member 122 is slidably connected to the annular groove 312, so that the propulsion unit 1121 can rotate in the annular groove 312 through the annular protrusion 11211 after abutting against each other.

[0054] In this embodiment, further, please refer to Figure 3 The restraining disk 31 is provided with a concave ring 311 for the restraining rope 32 to engage. Specifically, one main fan 11 and two secondary fan 12 are easy to disperse and fall off during the process of abutting each other, especially when the device hits the tree trunk, the main fan 11 and the secondary fan 12 are more likely to be misaligned due to vibration. Therefore, the restraining rope 32 is added to be tightly wound around the concave ring 311, so as to ensure that the main fan 11 and the secondary fan 12 fixedly connected to the restraining disk 31 always maintain a working state of abutting each other.

[0055] Preferably, there are two concave circles 311. After the device is assembled, two restraining ropes 32 are respectively wrapped around the two concave circles 311 to prevent one of the restraining ropes 32 from being damaged due to long-term operation of the device, and the other restraining rope 32 can be used as a guarantee.

[0056] In this embodiment, further, please refer to Figure 1A force-bearing protrusion 331 is provided below the support frame 33. Specifically, it is convenient to assist the support frame 33 to enter the soil. As the support frame 33 is inserted deeper into the soil, the force required for downward insertion is greater. The staff can strike the force-bearing protrusion 331 to make the support frame 33 more stably fixed.

[0057] In this embodiment, further, please refer to Figure 3 The bottom end of the support frame 33 is a pointed cone. Specifically, it is convenient for the support frame 33 to be quickly inserted into the soil and play a role in stabilizing the main push rod 113 and the secondary push rod 123 to hit the tree trunk without falling off.

[0058] In this embodiment, further, please refer to Figure 2 The driving mechanism 2 includes a worm 21 and a motor 22, and the output shaft of the motor 22 is fixedly connected to the end of the worm 21. Specifically, the combination of the motor 22 and the worm 21 can convert the impact in the linear direction into the operation in the circumference. With the improvement, the force storage range required for the impact can be reduced, the working space can be relieved, and it is more convenient for the staff to operate.

[0059] Preferably, the worm 21 is used in combination with the motor 22, so as to reduce the cost of the driving mechanism 2 and achieve the effect of hitting the tree trunk at three directions at the same time, thereby avoiding the tree trunk from tilting or even falling due to a late hit on the tree trunk from one direction.

[0060] Furthermore, the worm 21 can be converted into a rack, and the motor 22 can be converted into a cylinder. The output shaft of the cylinder is driven to extend and retract, driving the rack to operate back and forth, thereby driving the main rotating member 112 to rotate.

[0061] In this embodiment, further, please refer to Figure 5 The lower part of the main rotating member 112 is provided with gear teeth 1122 meshing with the worm 21. Specifically, when the worm 21 rotates, the threaded portion of the worm 21 drives the gear teeth 1122 to operate, and the gear teeth 1122 drive the main rotating member 112 to rotate. Under the drive of the main rotating member 112, the secondary rotating members 122 abutting against each other are driven to rotate in turn, and the propulsion unit 1121 completes the rotation action.

[0062] The specific working process of the present invention is as follows: first, the collision mechanism 1 is spliced, the annular protrusions 11211 below the main rotating member 112 and the secondary rotating member 122 are clamped in the annular groove 312, the upper inclined track is slidably clamped in the slider 1133, the cylindrical bar 11331 on the slider 1133 is inserted into the circular hole in an abutting manner, the rod body 1132 is slidably clamped in the groove slide rail 1111, and the rod head 1131 faces the tree trunk. After confirming that the interior of the main fan shell 111 and the secondary fan shell 121 are correct, the main fan member 11 and the secondary fan member 12 are clamped with each other through the concave buckle 1211 and the convex buckle 1112 with the tree trunk as the center, and then the two locking rods are locked. The rope 32 is wound around the concave circle 311 to complete the installation of the collision mechanism 1; then the support bracket 33 is adjusted to determine the height of the collision mechanism 1, and the staff uses the force-bearing convex column 331 to insert the soil under the action of the pointed cone-shaped support bracket 33, and firmly fixes the three support brackets 33, and supports the collision mechanism 1 and the driving mechanism 2 under the support of the restraining plate 31; finally, the motor 22 is started, and the gear 1122 is driven to drive the propulsion unit 1121 to rotate forward and backward under the alternating forward and reverse rotation of the worm 21, thereby achieving the effect of driving the main push rod 113 and the secondary push rod 123 to continuously hit the tree trunk, and the vibration of the tree trunk is transmitted to the branches, and the ripe dates fall.

[0063] The above are only preferred specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
