Walnut kernels are rich in nutrients, containing 15 - 20 grams of protein per 100 grams, relatively more fat, 10 grams of carbohydrates, and various trace elements and minerals such as calcium, phosphorus, and iron essential for the human body, as well as various vitamins such as carotene and riboflavin, which are beneficial to the human body.
[0003] When picking walnuts, since some fruits are at higher positions, people often use tools such as bamboo poles to knock the fruits at higher positions, usually knocking them down in this way. However, this picking method is quite labor - intensive, and excessive force can also damage the walnuts, resulting in damaged walnuts. In view of this, the present utility model specifically provides a walnut picking rack to solve the above problems. Content of the Utility Model

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.
[0024] As Figures 1 to 6 shown
[0025] A walnut picking rack, comprising a picking head 1. The picking head 1 is of a portal frame structure. Symmetrically arranged movable plates 5 are slidably installed on the inner wall of the picking head 1. Fixed rods 6 are fixedly connected to one side of each of the two movable plates 5. Symmetrically arranged cutting knives 7 are fixedly connected to the outer walls of the opposite sides of the two fixed rods 6. Arm rods 2 are fixedly connected to the outer wall of one side of the picking head 1. Movable grooves 8 are formed in the outer walls of the opposite sides of the two arm rods 2. Guide blocks 9 are slidably connected to the inner walls of the two movable grooves 8. A connecting seat 10 is fixedly connected to the outer walls of the opposite sides of the two guide blocks 9. An installation groove is formed in one side of the connecting seat 10, and symmetrically arranged movable rods 3 are hingedly installed in the installation groove. Connecting rods 15 are fixedly connected to the outer walls of one side of each of the two movable plates 5. Connecting grooves are formed at one end of each of the two connecting rods 15. One end of each of the two movable rods 3 is respectively hingedly installed in the two connecting grooves. A rectangular movable opening 14 is formed in the middle of one side of the picking head 1. The two connecting rods 15 are slidably connected to the inner wall of the rectangular movable opening 14. When carrying out the picking work, the picking personnel hold the hand-held plate 4 tightly, lift the picking head 1 to the position for walnut picking in cooperation with the two arm rods 2 provided, and then pull the sliding rod 11 to move by means of the hand-held rod 12 provided. The sliding rod 11 drives the connecting seat 10 to move in cooperation with the two movable grooves 8 and the two guide blocks 9 provided. The connecting seat 10 makes the inclination angles of the two movable rods 3 change in cooperation with the two connecting rods 15 provided. When the inclination angles of the two movable rods 3 change, the rectangular movable opening 14 provided can drive the two connecting rods 15 to move relatively in cooperation, so that the two connecting rods 15 drive the two movable plates 5 to move relatively. The two movable plates 5 can move relative to the two fixed rods 6. The two fixed rods 6 drive the two cutting knives 7 to move relatively, so that the relative movement of the two cutting knives 7 can cut off the walnut branches, thereby realizing the picking of walnuts.
[0026] In the specific implementation manner, the same hand-held plate 4 is fixedly connected to the end positions of the two arm rods 2. An activity hole is formed in the middle of the hand-held plate 4, and a sliding rod 11 is slidably connected to the inner wall of the activity hole. The right end of the sliding rod 11 is fixedly connected to the outer wall of one side of the connecting seat 10. A hand-held rod 12 is fixedly arranged at the left end of the sliding rod 11. A first spring 13 is fixedly connected to the outer wall of one side of the connecting seat 10. One end of the first spring 13 is fixedly connected to the outer wall of one side of the hand-held plate 4. The first spring 13 is sleeved on the sliding rod 11. After the picking is completed, the hand-held rod 12 is released. Under the action of the first spring 13, the connecting seat 10 is reset to the initial state. When the connecting seat 10 performs the reset movement, the two movable rods 3 and the two connecting rods 15 can be reset to the initial state.
[0027] Furthermore, symmetrically arranged fixing plates 16 are fixedly connected to both sides of the picking head 1. The same guiding rod 17 is fixedly connected to the outer walls of the opposite sides of the two fixing plates 16. Through holes are formed in both of the two movable plates 5, and the guiding rod 17 is slidably connected to the inner walls of the through holes. The same second spring 18 is fixedly connected to the outer walls of the opposite sides of the two movable plates 5. The second spring 18 is sleeved on the guiding rod 17. When the connecting seat 10 is reset to the initial state, the cooperating guiding rod 17 and the second spring 18 enable the two movable plates 5 and the two fixing rods 6 to be reset to the initial state, thereby realizing the reset function of the two cutting knives 7.
[0028] The implementation principle of a walnut picking rack in this embodiment is as follows:
[0029] During specific use, the picking personnel hold the handheld plate 4 tightly. The two arm rods 2 cooperate to lift the picking head 1 to the position for walnut picking. Then, the handheld rod 12 is used to pull the sliding rod 11 to move. The sliding rod 11 drives the connecting seat 10 to move in cooperation with the two movable grooves 8 and the two guiding blocks 9. The connecting seat 10 changes the inclination angles of the two movable rods 3 in cooperation with the two connecting rods 15. When the inclination angles of the two movable rods 3 change, the cooperating rectangular movable opening 14 can drive the two connecting rods 15 to move relatively, so that the two connecting rods 15 drive the two movable plates 5 to move relatively. The two movable plates 5 can move relatively to the two fixing rods 6. The two fixing rods 6 drive the two cutting knives 7 to move relatively, so that the relative movement of the two cutting knives 7 can cut off the walnut branches, thereby realizing the picking of walnuts. Then, the handheld rod 12 is released. Under the action of the first spring 13, the connecting seat 10 is reset to the initial state. When the connecting seat 10 performs the reset movement, the two movable rods 3 and the two connecting rods 15 can be reset to the initial state. The cooperating guiding rod 17 and the second spring 18 enable the two movable plates 5 and the two fixing rods 6 to be reset to the initial state, thereby realizing the reset function of the two cutting knives 7.
